[0052] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to user game data, user-uploaded stickers, etc.) involved in the present application are all information and data authorized by the user or fully authorized by all parties, and the collection, use, and processing of the relevant data need to comply with the relevant laws, regulations, and standards of the relevant countries and regions. For example, the information such as the setting operations involved in the present application are obtained under full authorization.

[0053] It should be understood that although the terms first, second, etc. may be used in the present disclosure to describe various information, these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present disclosure, the first parameter may also be referred to as the second parameter, and similarly, the second parameter may also be referred to as the first parameter. Depending on the context, the word "if" as used herein may be interpreted as "when" or "while" or "in response to determining".

[0054] First, the relevant terms involved in the present application are introduced:

[0055] UCG (User Generated Content): Refers to the original content created and shared by users on the Internet. In the game field, developers encourage users to participate in the design of game content such as level maps, gameplay, and ecosystems by providing corresponding UCG editing capabilities within the game. By allowing users to design game content, it enhances users' sense of belonging and enriches the game content, better meeting personalized needs.

[0056] Virtual environment: The virtual environment displayed (or provided) when the client runs on the terminal. This virtual environment can be a simulation of the real world, a semi-simulated and semi-fictional environment, or a purely fictional environment. The virtual environment can be any one of a two-dimensional virtual environment, a 2.5D virtual environment, and a three-dimensional virtual environment. This application does not limit this. The following embodiments take the virtual environment as a three-dimensional virtual environment as an example for illustration.

[0057] Particle generator: An editor used to generate particle effects. The particle generator can generate particles to form particle effects. The particle generator is usually added to application programs that require special effects production, such as post-processing software and game engines. Users can edit the particle effects finally generated by the particle generator by modifying the code of the particle generator or using the graphical interface opened by the particle generator, thus obtaining various particle effects.

[0058] Figure 1 and Figure 2 FIG. shows a schematic diagram of a computer system provided by an exemplary embodiment of the present application. The computer system may include: a terminal device 110, a server 120.

[0059] The terminal device 110 can be a laptop computer, a desktop computer, a mobile phone, a tablet computer, an e-book reader, an electronic game console, and so on.

[0060] The terminal device 110 includes a memory and a processor; the memory may include one or more computer-readable storage media. The above-mentioned computer-readable storage media include at least one of random access memory (RAM), read-only memory (ROM), and flash memory. An operating system and a game program are installed in the memory.

[0061] The game program can be any one of a level-clearing game, a casual competitive game, an MMOG (Massive Multiplayer Online Game), a board game, an MOBA (Multiplayer Online Battle Arena) game, an SLG (Simulation Game), a virtual reality application program, a 3D map program, an FPS (First-Person Shooting Game), a multiplayer gunfight survival game, a casual game, a party game, or a sandbox game.

[0062] Adding a UGC editor to the game program enables user 130 to participate in the design of the game program. The developer of the game program will provide user 130 with maps or levels designed by the developer, and user 130 can play these maps or levels. After adding a UGC editor to the game program, user 130 can design maps or levels by themselves through the UGC editor, and user 130 can also play these maps or levels, which can improve user 130's sense of participation and belonging to the game program. The UGC editor is a tool provided by the developer for user 130 to design maps or levels. The UGC editor includes interfaces opened by the developer to user 130. In order to simplify the production of maps or levels, these interfaces often exist in the form of a graphical interface, that is, user 130 can obtain a delicate and perfect map or level by simply clicking, swiping and other operations using the UGC editor.

[0063] The UGC editors added to different types of game programs have different focuses. For example, the UGC editors added to MMOG games and SLG games mainly play an auxiliary role. For example, it enables user 130 to edit the scenes in the home through the UGC editor, and the home is a virtual environment of a certain area belonging to user 130. Level-clearing games, casual competitive games, party games, and sandbox games often take the UGC editor as the main body, enabling user 130 to freely create maps or levels and share them with other users. In this type of game, the richness of the production functions provided by the UGC editor will largely affect the gaming experience of user 130.

[0064] The operating system is basic software that provides secure access to computer hardware for the game program. The operating system can be the Android system or the iOS system. The operating system supports the download, installation, and running of the game program.

[0065] Optionally, the terminal device 110 further includes a touch screen; the touch screen may be a capacitive screen or a resistive screen. The touch screen is used to implement interaction between the terminal device and the user 130. In an embodiment of the present application, the terminal device obtains the interactive operation of the editor interface 140 of the UGC editor in the game program triggered by the user 130 through the touch screen.

[0066] The terminal device 110 has a game program installed and running, and the game program is designed with an editor interface 140.

[0067] Editor interface 140 supports user 130 to edit, save, publish and other operations on the virtual environment. When editing the virtual environment, user 130 can use virtual objects to build different virtual environments. UGC editor supports user 130 to set particle effects for the virtual environment to enrich the virtual environment. The particle effects are generated by a particle generator to improve the operability and fun of the user.

[0068] Terminal device 110 is a terminal device used by a user. User 130 uses terminal device 110 to operate editor interface 140, and user 130 can save the virtual environment being edited or edited to terminal device 110. Optionally, terminal device 110 is used to upload the virtual environment information saved by user 130 to server 120; or, terminal device 110 is used to provide data information of the virtual environment and particle generator to the game program; or, terminal device 110 is used to save the attribute parameters of the particle generator.

[0069] In some embodiments, the computer system further includes a server 120, such as Figure 2 As shown. The server 120 can be any one of a plurality of servers, a virtual cloud storage or a cloud computing center. Optionally, the server 120 is used to store the virtual environment information uploaded by the terminal device 110; or, the server 120 is used to store the attribute parameters of the particle generator uploaded by the terminal device 110; or, the server 120 is used to provide the game program with data information of the virtual environment and the particle generator.

[0070] In some embodiments, the terminal device 110 and the server 120 are connected via a wired or wireless network.

[0071] Figure 3 A schematic diagram of a method for generating UGC special effects in a game program provided by an exemplary embodiment of the present application is shown. The method is executed by a terminal device, which may be as follows Figure 1 and Figure 2 The terminal device shown in . The method includes:

[0072] Step 210: Display the particle generator in the editor interface of the UGC editor;

[0073] In some embodiments, a virtual environment screen is displayed on the editor interface of the UGC editor. The virtual environment screen is obtained by a camera model capturing a three-dimensional virtual environment. A user can control the camera model through interactive operations on the touch screen to change the display effect of the virtual environment screen.

[0074] In some embodiments, a particle generator is an element for generating particles. The element can be added to the virtual environment. In some embodiments, the element can be used to decorate the virtual environment; or, the element can provide interaction for the user. The element can also be referred to as a component. A user can trigger at least one of an addition operation, a movement operation, a rotation operation, a scaling operation, a deletion operation, and an editing operation on the particle generator. The addition operation is used to add a new particle generator to the virtual environment; the movement operation is used to change the position of the particle generator in the virtual environment; the rotation operation is used to change the angle of the particle generator in the virtual environment; the scaling operation is used to change the size of the particle generator in the virtual environment; the deletion operation is used to delete the selected particle generator in the virtual environment; and the editing operation is used to change the attribute parameters of the particle generator.

[0075] In some embodiments, at least one particle generator is displayed on the editor interface of the UGC editor, and the at least one particle generators have the same or different attributes.

[0076] Step 220: In response to an attribute setting operation on the particle generator, set the attribute parameters of the particles generated by the particle generator;

[0077] In some embodiments, in response to an attribute setting operation on the particle generator, set the attribute parameters of the particles generated by the particle generator; or, in response to an editing operation on the particle generator, set the attribute parameters of the particles generated by the particle generator.

[0078] In some embodiments, the particles generated by the particle generator include at least one attribute parameter, which includes at least one of a color parameter, a scaling parameter, a transparency parameter, a brightness parameter, an emission speed, an emission position, a rotation angle, a rotation speed, a cycle period, a particle texture, a generation rate, and an acceleration. The color parameter is used to indicate the color of the particles generated by the particle generator during the cycle period; the scaling parameter is used to indicate the scaling degree of the particles generated by the particle generator during the cycle period, and this scaling degree is used to indicate the scaling ratio relative to the default particle size; the transparency parameter is used to indicate the transparency degree of the particles generated by the particle generator during the cycle period; the brightness parameter is used to indicate the brightness degree of the particles generated by the particle generator during the cycle period; the emission speed is used to indicate the initial movement speed of the particles generated by the particle generator, and the emission speed includes at least one of an x-axis emission speed, a y-axis emission speed, and a z-axis emission speed; the emission position is used to indicate the initial position of the particles generated by the particle generator; the rotation angle is used to indicate the initial rotation angle of the particles generated by the particle generator; the rotation speed is used to indicate the rotation speed of the particles generated by the particle generator; the cycle period is used to indicate the existence time of the particles generated by the particle generator; the particle texture is used to indicate the texture of the particles generated by the particle generator; the generation rate is used to indicate the number of particles generated by the particle generator in the first unit time; the acceleration is used to indicate the acceleration of the particles of the particle generator, and the acceleration includes at least one of an x-axis acceleration, a y-axis acceleration, and a z-axis acceleration.

[0079] Step 230: In response to a trigger operation for the particle generator, generate a particle special effect based on the attribute parameters, where the particle special effect includes at least one particle generated by the particle generator.

[0080] In some embodiments, in response to a trigger operation for the particle generator, the particle generator starts to generate particles based on the attribute parameters. At least one particle generated by the particle generator forms a particle special effect.

[0081] In summary, the method provided by the embodiments of the present application adds a user-customizable particle generator to the UGC editor. By adjusting the attribute parameters of the particle generator, the user can customize various particle special effects, enrich the special effects in the UGC editor, and meet the user's customization requirements.

[0082] In response to a user's attribute setting operation for the particle generator, the terminal device sets the attribute parameters of the particles generated by the particle generator. The present application shows three different attribute setting operations, and the attribute setting methods for the attribute parameters include but are not limited to at least one of the following three setting methods (the order does not represent the superiority or inferiority of the implementation methods):

[0083] Setting method one: Set the attribute parameters based on keyframe controls.

[0084] Setting method 2: Set the control based on the property parameter range to set the property parameter range.

[0085] Setting method 3: Directly set the property parameters.

[0086] It should be noted that for different property parameters, any one of the above three setting methods can be adopted, and the present application does not limit this.

[0087] The following will introduce the above three setting methods respectively.

[0088] Setting method 1 (Key frame control)

[0089] In an alternative embodiment based on Figure 3 Step 220 can be alternatively implemented as step 221 and step 222.

[0090] Step 221: In response to an attribute setting operation for the particle generator, display at least two key frame controls on the editor interface;

[0091] Among them, at least two key frame controls are used to edit the property parameter values of the particle at at least two key frame moments in the cycle period; the cycle period is used to indicate the time from the generation to the disappearance of the particle; each key frame control corresponds one-to-one with the key frame moment, and the key frame moment is the moment corresponding to the key frame control in the cycle period.

[0092] In some embodiments, the key frame control includes at least one of a button control (Button), an image button control (ImageButton), and a user-created control (User Created).

[0093] In some embodiments, in response to an attribute setting operation for the particle generator, at least two key frame controls are displayed on the editor interface. In some embodiments, the first key frame control is also referred to as the start frame control, and the last key frame control is also referred to as the end frame control.

[0094] In some embodiments, the key frame control is displayed as a simple graphic, such as a circle, a square, a triangle; or, the key frame control is displayed as an icon.

[0095] In some embodiments, when the key frame control is in the selected state, the key frame control is highlighted. Exemplarily, the key frame control is displayed as a circle, and the key frame control in the selected state is displayed as a ring, and the ring is highlighted.

[0096] In some embodiments, the property parameter of the particle includes a cycle period, and the cycle period is used to indicate the time from the generation to the disappearance of the particle.

[0097] In some embodiments, the attribute parameters of the particles are related to the cycle period. When setting the attribute parameters using the keyframe controls, each keyframe control corresponds to a moment in the cycle period, and this moment is the keyframe moment corresponding to the keyframe control.

[0098] In some embodiments, the start frame control corresponds to the start of a cycle period, that is, the keyframe moment corresponding to the start frame control is the 0th second when the particle is generated; the end frame control corresponds to the end of a cycle period, that is, the keyframe moment corresponding to the end frame control is the current moment when the particle disappears, that is, the moment corresponding to the upper limit of the cycle period.

[0099] Step 222: In response to a trigger operation on the i-th keyframe control among at least two keyframe controls, determine that the value of the attribute parameter of the particle at the i-th keyframe moment is the value of the attribute parameter corresponding to the i-th keyframe control.

[0100] Wherein, i is a positive integer.

[0101] In some embodiments, in response to a trigger operation on the i-th keyframe control among at least two keyframe controls, determine that the value of the attribute parameter of the particle at the i-th keyframe moment is the value of the attribute parameter corresponding to the i-th keyframe control. Exemplarily, if the user sets the attribute parameter value to 1 through the i-th keyframe control, then the value of the attribute parameter of the particle at the i-th keyframe moment is the attribute parameter value 1 set by the user through the i-th keyframe control.

[0102] In some embodiments, the values of the property parameters of the particles in the cycle period change one by one according to the property parameter values respectively corresponding to the first keyframe control to the last keyframe control, that is, mutation. For example, there are 4 keyframe controls, and the corresponding property parameter values are 0, 3, 2, and 4 respectively. The cycle period of the particles is 3 seconds, and the keyframe times corresponding to the 4 keyframe controls are the 0th second, the 1st second, the 2nd second, and the 3rd second respectively. Then the property parameter value of the particle is 0 from the 0th to the 1st second, mutates to 3 at the 1st second, is 3 from the 1st to the 2nd second, mutates to 2 at the 2nd second, is 2 from the 2nd to the 3rd second, mutates to 4 at the 3rd second, and then the particle disappears; or, the values of the property parameters of the particles in the cycle period change gradually according to the property parameter values respectively corresponding to the first keyframe control to the last keyframe control, that is, gradual change. The gradual change process of the property parameter values satisfies a straight line with adjacent two keyframe controls as endpoints, or the gradual change process of the property parameter values satisfies a curve passing through adjacent two keyframe controls. For example, there are 3 keyframe controls, and the corresponding property parameter values are 0, 1, and 0 respectively. The cycle period of the particles is 3 seconds, and the keyframe times corresponding to the 3 keyframe controls are the 0th second, the 1st second, and the 3rd second respectively. Then it can be obtained that the straight line between the 1st keyframe control and the 2nd keyframe control is y = x, and the straight line between the 2nd keyframe control and the 3rd keyframe control is y = -0.5x + 1.5, where x is the time corresponding to the cycle period, and y is the property parameter value of the particle. That is, the relationship between the property parameter value of the particle from the 0th to the 1st second and the time corresponding to the cycle period satisfies the straight line y = x. For example, the property parameter value at the 0.5th second is 0.5; the relationship between the property parameter value from the 1st to the 3rd second and the time corresponding to the cycle period satisfies y = -0.5x + 1.5. For example, the property parameter value at the 2nd second is 0.5.

[0103] In summary, the method provided by the embodiments of the present application provides a way for users to set property parameters using keyframe controls. Since each keyframe control corresponds to a keyframe time in the cycle period, that is, users can set the property parameter values of the particles at a certain keyframe time in the cycle period through the keyframe controls. Through this method, the changes of the property parameters of the particles generated by the particle generator in the cycle period can be set flexibly.

[0104] In some embodiments, the particles generated by the particle generator include at least one property parameter, and the property parameter includes at least one of a color parameter, a scaling parameter, a transparency parameter, a brightness parameter, an emission speed, an emission position, a rotation angle, a rotation speed, a cycle period, a particle texture map, a generation rate, and an acceleration.

[0105] The user can use setting method 1 to set one or more of the above several property parameters. Optionally, the property parameters set using setting method 1 include at least one of a color parameter, a scaling parameter, a transparency parameter, and a brightness parameter.

[0106] The following will separately introduce the setting methods for setting property parameters using keyframe controls.

[0107] 1.1 Setting the color parameter using keyframe controls

[0108] In some embodiments, the color parameter is used to indicate the color of the particles generated by the particle generator during the cycle period.

[0109] In some embodiments, step 221 can be implemented as step 2211, and step 222 can be implemented as step 2221.

[0110] Step 2211: In response to a trigger operation on the color setting entry of the particle generator, at least one of at least two color keyframe controls, a color coordinate axis, a particle color selection tab page, and a particle color selection operation control is displayed on the editor interface;

[0111] Among them, at least two color keyframe controls are located in the color coordinate axis; the color coordinate axis is used to indicate the color change of the particles during the cycle period; the particle color selection tab page is used to indicate the color selection method; the particle color selection tab page includes at least one of a color palette tab page, a color palette tab page, and a history tab page; different particle color selection tab pages correspond to different particle color selection operation controls; the color palette tab page corresponds to a color palette color selection control; the color palette tab page corresponds to a color palette color selection control; the history tab page corresponds to a history color selection control; the particle color selection operation control is used to select a color from at least one candidate color.

[0112] In some embodiments, the color keyframe control includes at least one of a button control, an image button control, and a user-created control; the color coordinate axis includes at least one of an image control (Image), an image view (ImageView), and a user-created control; the particle color selection tab page includes at least one of a tab layout control (TabLayout) and a user-created control; the particle color selection operation control includes at least one of a button control, an image button control, an image control, and an image view.

[0113] In some embodiments, the color coordinate axis is used to indicate the color change of the particles during the cycle period, and the two ends of the color coordinate axis respectively correspond to the first color keyframe control and the last color keyframe control, that is, the start frame control and the end frame control.

[0114] In some embodiments, such as Figure 4As shown, the particle color selection tab page includes at least one of a color palette tab page 87, a color mixing palette tab page 88, and a history tab page 89. As Figure 4 shown in the schematic diagram (1) in Figure 4 , the color palette tab page 87 corresponds to a color palette color selection control 90, and the color palette color selection control 90 is used to select a color from at least one candidate color. The color palette tab page 87 further includes a color palette switching control 91, and the color palette switching control 91 is used to switch the candidate colors of different color combinations. As Figure 4 shown in the schematic diagram (2) in Figure 4 , the color mixing palette tab page 88 corresponds to a color mixing palette color selection control 92, and the color mixing palette color selection control includes a color wheel control 93 and a brightness control 94. The color wheel control 93 is an RGB (Red Green Blue) color wheel or an RYB (Red Yellow Blue) color wheel, that is, a color selection range obtained by mixing primary colors of red, green, and blue or red, yellow, and blue respectively. The brightness control 94 is used to indicate the intensity of the color brightness. The brightness change displayed by the brightness control 94 is that the brightness increases from bottom to top, that is, gradually transitions from black to white, and the brightness decreases from left to right, that is, gradually changes from white to black. When the user performs a color selection operation on the color wheel control, the brightness control displays the brightness transformation information corresponding to the color selected in the color wheel control. As Figure 4 shown in the schematic diagram (3) in Figure 4 , the history tab page 89 corresponds to a history color selection control 95, and the colors in the history tab page 89 are the colors that the user has selected or used.

[0115] Step 2221: When the i-th color key frame control among at least two color key frame controls is in a selected state, in response to a trigger operation on the particle color selection operation control, determine that the attribute parameter value of the particle at the i-th key frame moment is the color value selected by the particle color selection operation control.

[0116] Wherein, i is a positive integer.

[0117] Exemplarily, there are 3 color key frame controls, the user selects the 2nd color key frame control, the color selection tab page includes a color palette tab page, a color mixing palette tab page, and a history tab page. The user selects a color through the color palette color selection control on the color palette tab page, and the color value selected by the user through the color palette color selection control is set as the color value of the particle at the 2nd key moment; or, the user selects a color through the color mixing palette color selection control on the color mixing palette tab page, and the color value selected by the user through the color mixing palette color selection control is set as the color value of the particle at the 2nd key moment.

[0118] In summary, the method provided by the embodiments of the present application provides a user with an operation method for setting color parameters using a color keyframe control. When the user selects a color, the user can select a color through any one of three different color selection methods and set the selected color value as the color value of the corresponding particle at the keyframe moment. Among the three color selection methods provided, the color palette color selection is convenient and fast, and the color palette can be set to different styles to facilitate the user to select colors of the corresponding styles; the color palette color selection supports a richer range of colors and can provide a larger color selection range for the user; the historical color selection can save the colors that the user has used or selected, enabling the user to obtain special colors obtained by previous color adjustment without re-coloring, and the historical color selection is convenient for the user to unify the color tone when designing a virtual environment. On the one hand, it enables the user to have a larger operation control and selection range when selecting a color, and on the other hand, the user can change the color of the particle through this operation, making the color effect of the customized special effect richer.

[0119] When setting attributes using the keyframe control, in addition to the method of setting color parameters described above, the following methods are also included.

[0123] In some embodiments, the first coordinate axis is the horizontal axis and the second coordinate axis is the vertical axis; or, the first coordinate axis is the vertical axis and the second coordinate axis is the horizontal axis. It should be noted that the embodiments of the present application take the first coordinate axis as the horizontal axis and the second coordinate axis as the vertical axis as an example for illustration, but the specific directions of the first coordinate axis and the second coordinate axis are not limited.

[0125] Step 2222: When the i-th keyframe control among at least two keyframe controls is in a selected state, in response to a dragging operation on the i-th keyframe control, determine that the attribute parameter value of the particle at the i-th keyframe moment is the attribute parameter value corresponding to the i-th keyframe control in the attribute coordinate system.

[0126] Wherein, i is a positive integer.

[0127] In some embodiments, the corresponding attribute parameter value is displayed on the keyframe control.

[0128] In some embodiments, the 1st keyframe control and the last keyframe control, namely the start frame control and the end frame control, can only be dragged up and down, but cannot be dragged left and right. It can be understood that the abscissa corresponding to the start frame control and the end frame control cannot be changed, and only the ordinate corresponding to them can be changed.

[0129] In summary, the method provided by the embodiments of the present application shows a way to set attribute parameters based on keyframe controls. At least two keyframe controls of this way are located in the attribute coordinate system, and the user can change the attribute parameter value corresponding to the keyframe control and the specific time corresponding to the keyframe moment by dragging.

[0134] In some embodiments, the scaling parameter is used to indicate the scaling degree of the particles generated by the particle generator during the cycle period, and this scaling degree is relative to the default particle size. The minimum value of the particle scaling parameter is 0. When the particle scaling parameter is 0, the particle size is 0 times the default particle size; when the particle scaling parameter is 1, the particle size is 1 times the default particle size; when the particle scaling parameter is 2.5, the particle size is 2.5 times the default particle size.

[0135] In some embodiments, the upper limit of the scaling parameter is a preset value. Exemplarily, the upper limit of the scaling parameter is 10.

[0136] Exemplarily, as Figure 5 shown in the schematic diagram (1), the scaling coordinate system 96 is a rectangular coordinate system with the cycle period as the horizontal axis and the scaling parameter as the vertical axis, and the scaling coordinate system 96 includes the first quadrant of the rectangular coordinate system.

The value range of the transparency parameter is from 0 to 1. When the transparency is 0, the particles are displayed as completely opaque, and when the transparency is 1, the particles are displayed as completely transparent.

The value of the brightness parameter can be negative. When the absolute value of the brightness parameter value is a larger negative value, the particles appear darker, that is, closer to black; when the brightness parameter value is 0, no additional brightness is added to the particles, and the particle color is directly displayed; when the brightness parameter is a larger positive value, the particles appear brighter.

[0163] In some embodiments, the lower limit of the brightness parameter is a preset value. Exemplarily, the upper limit of the brightness parameter is -10.

[0164] Exemplarily, as Figure 5 shown in the schematic diagram (3) of, the brightness coordinate system 98 is a rectangular coordinate system in a plane with the cycle period as the horizontal axis and the brightness parameter as the vertical axis. The brightness coordinate system 98 includes the first quadrant and the fourth quadrant of the rectangular coordinate system.

[0165] In some embodiments, the upper limit of the abscissa value of the brightness coordinate system is the upper limit of the cycle period; or, the upper limit of the abscissa value of the brightness coordinate system is the cycle period.

[0166] Step 360: When the i-th brightness keyframe control among at least two brightness keyframe controls is in the selected state, in response to the drag operation on the i-th brightness keyframe control, determine that the attribute parameter value of the particle at the i-th keyframe moment is the brightness parameter value corresponding to the i-th brightness keyframe control in the brightness coordinate system.

[0167] Wherein, i is a positive integer.

[0168] In some embodiments, the corresponding brightness parameter value is displayed on the brightness keyframe control.

[0169] In some embodiments, the at least two brightness keyframe controls include two initial brightness keyframe controls, that is, the 1st and the last brightness keyframe controls, which can also be referred to as the brightness start frame control and the brightness end frame control.

At least two brightness keyframe controls of this method are located in the brightness coordinate system. Users can change the brightness parameter value corresponding to the brightness keyframe control and the specific time corresponding to the keyframe moment by dragging. This method facilitates users to adjust the change trend of the brightness parameter value, enabling users to more conveniently customize the brightness or darkness of the particles changing based on the cycle period.

[0172] In some embodiments, the attribute parameter corresponds to at least two keyframe controls, and among the at least two keyframe controls, there are two initial keyframe controls, namely the first keyframe control and the last keyframe control, which can also be referred to as the start frame control and the end frame control. In addition to the two initial keyframe controls, the user can also add or delete keyframe controls. Next, the methods of adding keyframe controls and deleting keyframe controls are shown.

[0173] · Adding keyframe controls

[0174] Step 410: When the i-th keyframe control is in the selected state, in response to the add keyframe operation, when the attribute parameter corresponds to n keyframe controls, insert a new keyframe control between the i-th keyframe control and the (i + 1)-th keyframe control to obtain n + 1 keyframe controls corresponding to the attribute parameter.

[0175] Wherein, i is a positive integer and n is a positive integer.

[0176] In some embodiments, the keyframe control includes at least one of a button control, an image button control, and a user-created control.

[0177] In some embodiments, n is a positive integer not less than 2.

[0178] In some embodiments, when the i-th keyframe control is in the selected state, in response to the add keyframe operation, when the attribute parameter corresponds to n keyframe controls, insert a new keyframe control between the (i - 1)-th keyframe and the i-th keyframe control to obtain n + 1 keyframe controls corresponding to the attribute parameter, and the i-th keyframe control among the n keyframe controls is postponed to be the (i + 1)-th keyframe control among the n + 1 keyframe controls. Or, when the i-th keyframe control is in the selected state, in response to the add keyframe operation, when the attribute parameter corresponds to n keyframe controls, insert a new keyframe control between the i-th keyframe control and the (i + 1)-th keyframe control to obtain n + 1 keyframe controls corresponding to the attribute parameter, and the (i + 1)-th keyframe control among the n keyframe controls is postponed to be the (i + 2)-th keyframe control among the n + 1 keyframe controls.

[0179] In some embodiments, the attribute parameter value corresponding to the new keyframe control is the average of the attribute parameter values of the i-th and (i + 1)-th keyframe controls among the n keyframe controls; or, the attribute parameter value corresponding to the new keyframe control is the average of the attribute parameter values of the (i - 1)-th and i-th keyframe controls among the n keyframe controls; or, the attribute parameter value corresponding to the new keyframe control is a preset value.

The (i + 1)-th keyframe control among the n keyframe controls becomes the i-th keyframe control among the n - 1 keyframe controls, where n is a positive integer.

[0186] In some embodiments, the i-th keyframe control is not the first keyframe control; the i-th keyframe control is not the last keyframe control.

[0187] In some embodiments, when the i-th keyframe control is the first keyframe control, the second keyframe control among the n keyframe controls becomes the first keyframe control among the n - 1 keyframe controls, and the keyframe time corresponding to the second keyframe control among the n keyframe controls becomes the keyframe time of the deleted first keyframe control; when the i-th keyframe control is the n-th keyframe control, the (n - 1)-th keyframe control among the n keyframe controls remains the (n - 1)-th keyframe control among the n - 1 keyframe controls, and the keyframe time corresponding to the (n - 1)-th keyframe control among the n keyframe controls becomes the keyframe time of the deleted n-th keyframe control, where n is a positive integer.

[0328] Step 920: In response to an attribute setting operation for the minimum rotation speed setting control, determine the minimum value of the rotation speed range of the particle.

[0329] In some embodiments, the maximum value of the rotation speed range is set by the user through the maximum rotation speed setting control; or, the maximum value of the rotation speed range is a preset value. Exemplarily, the maximum value of the rotation speed range is the preset value 0.

[0330] In some embodiments, the maximum value of the rotation speed range is greater than or equal to the minimum value of the rotation speed range.

[0331] In some embodiments, when the maximum value of the rotation speed range is equal to the minimum value of the rotation speed range, the randomly generated rotation angle value of the particle is constantly the maximum value or the minimum value of the rotation speed range.

[0332] In summary, the method provided by the embodiments of the present application determines the value range of the randomly generated rotation speed value of the particle by setting at least one of the maximum value and the minimum value of the rotation speed range. After using the above method, the user can make the particles generated by the particle generator have a random rotation speed, so that the particle special effects include particles that do rotational motion, making the user-defined particle special effects more diverse.

[0333] Setting method three (directly setting attribute parameter values)

[0334] Based on Figure 3In an alternative embodiment, step 220 may be implemented as step 224.

[0335] Step 224: Determine the value of the particle's attribute parameter in response to an attribute setting operation for the particle generator.

[0336] In some embodiments, the user directly determines the value of the particle's attribute parameter through an attribute setting operation. The attribute parameter corresponding to all the particles generated by the particle generator is this value of the attribute parameter.

[0337] In summary, the method provided by the embodiments of the present application shows a method for setting an attribute parameter. It is set by simply setting a numerical value, which is simple and easy to operate, enabling the user to quickly customize the particle special effects based on the attribute setting operation interface provided by the developer.

[0338] In some embodiments, the particles generated by the particle generator include at least one attribute parameter, and the attribute parameter includes at least one of a color parameter, a scaling parameter, a transparency parameter, a brightness parameter, an emission speed, an emission position, a rotation angle, a rotation speed, a cycle period, a particle texture, a generation rate, and an acceleration.

[0339] The user can use setting method three to set one or more of the above several attribute parameters. Optionally, the attribute parameters set using setting method two include at least one of a cycle period, an emission position, a particle texture, a generation rate, and an acceleration.

[0340] The following will separately introduce the setting methods for setting attribute parameters using an attribute parameter range.

[0341] 3.1 Directly setting the cycle period

[0342] In some embodiments, the cycle period is used to indicate the existence time of the particles generated by the particle generator, that is, the time from the generation to the disappearance of the particles.

[0343] In some embodiments, a cycle period setting control is displayed on the editor interface.

[0344] In some embodiments, the cycle period setting control includes at least one of a button control, an image button control, a drag bar control, a progress bar control, a slider control, a text box control, a digital display box control, and a user-created control.

[0345] In some embodiments, step 224 may be implemented as step 2241.

[0346] Step 2241: Determine the cycle period value of the particle in response to an attribute setting operation for the cycle period setting control.

[0347] In some embodiments, the cycle period value of the particles is the cycle period value of all the particles generated by the particle generator. For example, if the cycle period value of particle generator a is 5 and the cycle period value of particle generator b is 2, then the cycle period value of all the particles generated by particle generator a is 5, and the cycle period value of all the particles generated by particle generator b is 2; or, the cycle period value of the particles is the maximum cycle period value of the particles.

[0455] In some embodiments, when the x-axis acceleration of a particle is positive, the acceleration direction is the positive half-axis direction of the x-axis; when the x-axis acceleration of the particle is negative, the acceleration direction is the negative half-axis direction of the x-axis; when the y-axis acceleration of the particle is positive, the acceleration direction is the positive half-axis direction of the y-axis; when the y-axis acceleration of the particle is negative, the acceleration direction is the negative half-axis direction of the y-axis; when the z-axis acceleration of the particle is positive, the acceleration direction is the positive half-axis direction of the z-axis; when the z-axis acceleration of the particle is negative, the acceleration direction is the negative half-axis direction of the z-axis.

[0456] In some embodiments, in response to an operation of setting the x-axis acceleration of a particle generator in an editing area, a particle special effect generated by the particle generator based on the x-axis acceleration is displayed in a preview area.

[0457] In some embodiments, in response to an operation of setting the y-axis acceleration of a particle generator in an editing area, a particle special effect generated by the particle generator based on the y-axis acceleration is displayed in a preview area.

[0458] In some embodiments, in response to an operation of setting the z-axis acceleration of a particle generator in an editing area, a particle special effect generated by the particle generator based on the z-axis acceleration is displayed in a preview area.

[0459] Exemplarily, when the particle's emission velocity along the x-axis is positive and the acceleration along the x-axis is positive, the particle moves with acceleration along the positive half-axis of the x-axis; when the particle's emission velocity along the x-axis is positive and the acceleration along the x-axis is negative, the particle moves with deceleration along the positive half-axis of the x-axis. When the velocity reduces to 0, the particle stops moving, or, the particle velocity is continuously calculated to obtain a negative particle velocity, and the particle moves with acceleration along the negative half-axis of the x-axis; when the particle's emission velocity along the x-axis is negative and the acceleration along the x-axis is negative, the particle moves with acceleration along the negative half-axis of the x-axis; when the particle's emission velocity along the x-axis is negative and the acceleration along the x-axis is positive, the particle moves with deceleration along the negative half-axis of the x-axis. When the velocity reduces to 0, the particle stops moving, or, the particle velocity is continuously calculated to obtain a positive particle velocity, and the particle moves with acceleration along the positive half-axis of the x-axis.

[0460] Exemplarily, when the particle's emission velocity along the x-axis is positive, the emission velocities along the y-axis and z-axis are both 0, the acceleration along the y-axis is positive, and the accelerations along the x-axis and z-axis are 0, the final motion trajectory of the particle is a curvilinear motion in the direction of the positive half-axis of the x-axis, and the curvature of this curve is positively correlated with the magnitude of the acceleration.

[0461] In some embodiments, the particle generator includes a base, and the base is used to identify the particle generator. As Figure 10 shown in the schematic diagram (3), the base 85 of the particle generator will be hidden in the playing interface of the UGC editor. As Figure 10 shown in the schematic diagrams (1) and (2), it will be displayed in the editor interface of the UGC editor.

[0462] Since in the UGC editor, users usually add at least one particle generator. In order to identify different particle generators, different particle generators can be distinguished by setting the base color.

[0463] In some alternative embodiments, the method further includes step 240.

[0464] Step 240: In response to an operation of setting the base color of the particle generator, set the base color of the particle generator. The base of the particle generator is used to indicate at least one of the position and angle of the particle generator in the virtual environment in the editor interface.

[0465] In some embodiments, the base of the particle generator is a simple graphic; or, the base is a graphic set by the user. Exemplarily, the base is a cuboid.

[0466] In some embodiments, the center of the base coincides with the center of the particle generator. The base will change its position as the particle generator moves, change its angle as the particle generator rotates, and change its size as the particle generator scales.

[0467] In some embodiments, the base color includes a base background color and a base top color, and step 240 can be implemented as step 241 or step 242.

[0468] In some embodiments, in response to a trigger operation on the base color setting entry for the particle generator, at least one of a base background color control, a base top color control, a base color selection tab page, and a base color selection operation control is displayed on the editor interface.

[0469] In some embodiments, the base color setting entry includes at least one of a button control, an image button control, a combo box control, and a user-created control; the base background color control includes at least one of a button control, an image button control, and a user-created control; the base top color control includes at least one of a button control, an image button control, and a user-created control; the base color selection tab page includes at least one of a tab layout control and a user-created control; the base color selection operation control includes at least one of a button control, an image button control, an image control, and an image view.

[0470] Step 241: When the base background color control is in a selected state, in response to a trigger operation on the base color selection operation control, determine that the base background color of the particle generator is the color value selected in the base color selection operation control.

[0471] Wherein, the base color selection tab page is used to indicate the color selection method; the base color selection tab page includes at least one of a color palette tab page, a color mixer tab page, and a history tab page; different base color selection tab pages correspond to different base color selection operation controls; the color palette tab page corresponds to a color palette color selection control; the color mixer tab page corresponds to a color mixer color selection control; the history tab page corresponds to a history color selection control; the base color selection operation control is used to select a color from at least one candidate color.

[0472] Step 242: When the base top color control is in a selected state, in response to a trigger operation on the second color selection operation control, determine that the base top color of the particle generator is the color value selected in the base color selection operation control.

[0473] In some embodiments, the method of setting the base background color and the base top color is similar to that of setting the particle color using the keyframe control in 1.1 above, and will not be elaborated here.

[0474] In some embodiments, the editor interface includes a preview area and an editing area. The preview area is used to preview the particles generated by the particle generator, and the editing area is used to set the attribute parameters of the particle generator.

[0475] In some embodiments, in response to an operation for setting the base color of the particle editor in the editing area, the set base color of the particle generator is displayed in the preview area. The base color includes a gradient color that gradually changes from the base bottom color to the base top color from bottom to top, or a gradient color that gradually changes from the base top color to the base bottom color from top to bottom.

[0476] In summary, the method provided by the embodiments of the present application sets the color for the base of the particle generator, so as to be able to identify multiple particle generators in the virtual environment on the editor interface, which is more convenient for the user to select different particle generators.

[0477] In some embodiments, the method further includes step 250 or step 260.

[0478] Step 250: In response to a selection operation on the particle generator, set the particle generator to the selected state, and add an indication box to the particle generator. The indication box is used to indicate the selected state.

[0479] In some embodiments, as Figure 10 shown in the schematic diagram (1), in response to a selection operation on the particle generator, set the particle generator to the selected state, and add an indication box 86 to the particle generator. The indication box 86 is used to indicate that the particle generator is in the selected state.

[0480] Step 260: In response to an editing operation on the particle generator, keep the particle generator in the selected state, and hide the indication box.

[0481] In some embodiments, as Figure 10 shown in the schematic diagram (2), in response to an editing operation on the particle generator, keep the particle generator in the selected state, and hide the indication box 86.

[0482] In summary, the method provided by the embodiments of the present application can display an indication box when the user selects a particle generator, indicating that the user has selected the particle generator; when the user edits the particle generator, the indication box is hidden, enabling the user to more conveniently observe the impact of the editing operation on the particles generated by the particle generator, and making it more convenient for the user to perform fine editing on the particles.

[0483] In some embodiments, the method further includes step 270.

[0484] Step 270: In response to an operation for setting the trigger signal of the particle generator, set the trigger signal of the particle generator.

[0485] Among them, the trigger signal includes at least one of an automatically generated signal, an open signal, and a close signal; the automatically generated signal is used to instruct the particle generator to automatically generate particles; the open signal is used to instruct the particle generator to start generating particles based on the open signal; the close signal is used to instruct the particle generator to stop generating particles based on the close signal.

[0486] In some embodiments, the particle generator is set not to play automatically, that is, the automatically generated signal is not set, and an open signal is set for the particle generator, so that the particle generator can generate particles only when the open signal is triggered; or, the particle generator is set not to play automatically, that is, the automatically generated signal is not set, and an open signal and a close signal are set for the particle generator, so that whether particles are generated can be freely controlled by triggering the open signal and the close signal of the particle generator; or, the particle generator is set to play automatically, that is, an automatically generated signal is set for the particle generator, and a close signal is set for the particle generator, so that when the close signal is triggered, the generation of particles stops.

[0487] In some embodiments, the trigger signal of the particle generator is bound to a signal trigger or a signal trigger control.

[0488] In some embodiments, the signal trigger is displayed in the virtual environment, or the signal trigger control is displayed in the editor interface.

[0489] In some embodiments, the signal trigger control includes at least one of a button control, an image button control, and a user-created control.

[0490] In some embodiments, a signal trigger is set for the particle generator in the virtual environment. In response to the signal trigger receiving a first trigger signal, the particle generator is controlled to generate particles. Exemplarily, the first trigger signal corresponds to the open signal of the particle generator, and the particle generator is controlled to start generating particles; or, the first trigger signal corresponds to the close signal of the particle generator, and the particle generator is controlled to stop generating particles.

[0491] In some embodiments, a signal trigger control is displayed in the editor interface. In response to the signal trigger control receiving a second trigger signal, the particle generator is controlled to generate particles. Exemplarily, the second trigger signal corresponds to the open signal of the particle generator, and the particle generator is controlled to start generating particles; or, the second trigger signal corresponds to the close signal of the particle generator, and the particle generator is controlled to stop generating particles.

[0492] In some embodiments, the signal trigger and the signal trigger control can be used simultaneously. Exemplarily, the first trigger signal corresponds to the open signal of the particle generator, and the particle generator is controlled to start generating particles; the second trigger signal corresponds to the close signal of the particle generator, and the particle generator is controlled to stop generating particles.

[0493] In summary, the method provided by the embodiments of the present application can set a trigger signal for the particle generator to control whether the particle generator generates particles. Only when the trigger signal is satisfied, the generation or stop of particles is performed, enabling the user to independently control whether the particle special effect is generated and increasing the freedom of generating the particle special effect.

[0494] In some embodiments, the method further includes step 280.

[0495] Step 280: Set the motion mode of the particle generator in response to a motion control operation for the particle generator;

[0496] Among them, the motion mode of the particle generator includes one of a full - scale motion mode, a one - way displacement mode, a reciprocating displacement, a one - way rotation mode, a swinging motion mode, and a waypoint motion mode.

[0497] Different motion modes correspond to different motion attributes. Optionally, the motion attributes include at least one of a motion start signal, a motion stop signal, a motion return signal, and a motion cycle form. After receiving the motion start signal, the motion unit switches to the active state. If the activation signal is empty, the motion unit is default in the active state after the game starts, otherwise it is in the paused state; after receiving the motion stop signal, the motion unit switches to the paused state, and the time calculation of the life cycle is not included in the paused state; the motion return signal is only allowed to be configured in the one - way motion mode, and reverse motion is activated after receiving the signal.

[0498] Among them, the waypoint motion mode is used to indicate that the virtual object moves along a motion path formed by at least two waypoints. The positions, rotations, and scalings of at least two waypoints are the same or different. The waypoint is used to indicate at least one of the position, rotation, and scaling of the virtual object when the virtual object moves to this waypoint; the one - way displacement mode is used to indicate a single - time uniform motion on a straight line and stops after the motion ends. The user can set the motion duration of the single - time motion, etc., to control the single - time motion; the reciprocating displacement is used to indicate a uniform round - trip motion on the same straight line; the one - way rotation mode is used to indicate that the virtual object performs a uniform rotation motion with an unchanged axis, and the axis is the center of the virtual object; the swinging motion mode is used to indicate a rotational swing with an unchanged axis, such as a pendulum, etc.; the full - scale motion mode is used to indicate motion according to the motion logic. In the full - scale motion mode, all motion performances can be achieved through settings, such as at least one of the above - mentioned one - way displacement mode, reciprocating displacement, one - way rotation mode, and swinging motion mode. The full - scale motion mode can also set variable - speed motion, etc.

[0499] In summary, the method provided by the embodiments of the present application can add motion control to the particle generator, and only simple graphical operations are required when adding motion control, enabling the particle generator to move in the virtual environment, thereby making the final particle special effects richer.

[0500] In order to more clearly understand the various display modes and operation modes of the embodiments of the present application, the following will be described in detail with reference to the schematic diagrams.

[0501] · The particle generator in the virtual environment displayed on the editor interface of the UGC editor

[0502] The particle generator is a component in the UGC editor. The particle generator can generate particles in the virtual environment, and through the particles, effects such as dust, sparks, smoke, raindrops, etc. can be simulated. Using the particle generator can add special effects to the virtual environment.

[0503] Figure 11 The figure shows a schematic diagram of the UGC special effect generation method in the game program provided by an exemplary embodiment of the present application.

[0504] The UGC editor includes an editor interface 10 and a gameplay interface. The editor interface 10 includes at least one of a virtual environment screen 11 and a control display area 12. The virtual environment screen 11 displays a particle generator 13 located in the virtual environment.

[0505] Among them, the virtual environment screen 11 is a screen obtained by collecting the three-dimensional virtual environment through a camera model. The user can control the camera model through interactive operations on the touch screen to change the display effect of the virtual environment screen 10; the control display area 12 is used to display the controls for editing the particle generator, including at least one of a movement control, a rotation control, a scaling control, a mirror control, a deletion control, and an editing control.

[0506] When the user selects the particle generator 13 through the editor interface 10, a details area 14 will be displayed in the right area of the editor interface 10; or, when the user selects the particle generator 13 and clicks on the editing control in the control display area 12, a details area 14 will be displayed in the right area of the editor interface 10. The user makes the details area 14 display an appearance area 16 through a click operation on the appearance editing control 15 in the details area 14.

[0507] The editor interface 10 also includes a details collapse control. Based on the user's click operation on the details collapse control, the details area 14 can be hidden from the editor interface 10.

[0508] When the particle generator 13 is selected, such as Figure 10As shown in the schematic diagram (1), the particle generator 13 is in the selected state, and the particle generator 13 has an indication box 17; when the user performs an editing operation on the particle generator 13, the particle generator 13 is in the selected state, but the indication box 17 is hidden, as Figure 10 shown in the schematic diagram (2).

[0509] · Edit the particle generator

[0510] 1. Set the base color

[0511] The base 18 of the particle generator is used to identify the particle generator. As Figure 10 shown in the schematic diagram (3), the base 18 of the particle generator will be hidden in the playing interface of the UGC editor and will be displayed in the editor interface 10 of the UGC editor.

[0512] The user can change the display form of the base of the particle generator in the skin setting area 19 of the appearance area 16. For example, change the color of the base 18. After the user clicks on the base color setting entry 20, the base color setting area 21 will be entered. The user can set different base colors for different particle generators through the base color setting area 21, so as to more conveniently and quickly distinguish different particle generators.

[0513] Among them, the user can set two colors for the particle generator, namely the base bottom color and the base top color. The base color shown in the editor interface 10 gradually transitions from the base bottom color to the base top color from bottom to top. In the base color setting entry 20, there are respectively displayed a base bottom color display control and a base top color display control.

[0514] As Figure 12As shown in the figure, the base color setting area 21 includes at least one of a base background color control 22, a base top color control 23, a color palette tab page 24, a color mixing palette tab page 25, a history tab page 26, a color selection operation control 27, a color storage area 28, and a color confirmation area 29. When the user triggers the base background color display control to enter the base color setting area 21, the base background color control 22 is in a selected state, that is, the color selection operation is performed on the base background color; when the user triggers the base top color display control to enter the base color setting area 21, the base top color control 23 is in a selected state, that is, the color selection operation is performed on the base top color. There are three color selection methods, each corresponding to a different tab page. The color storage area 28 includes a color storage control. When the color selection operation control is in a selected state, triggering the color storage control can store the color corresponding to the selected color selection operation control in the color storage area 28. The user can also determine whether to use the candidate color in the color confirmation area 29. After clicking the color confirmation control in the color confirmation area 29, the corresponding background color or top color of the base is modified to the currently selected color, and the base color setting area 21 is exited or the user still stays in the base color setting area 21.

[0515] As Figure 12 shown, the color palette tab page 24 includes 12 candidate colors, each candidate color corresponding to a color selection operation control. When the user selects a color selection operation control, the color selection operation control is in a selected state, and the color display control in the color confirmation area 29 also changes to the color consistent with the color corresponding to the color selection operation control and the color value corresponding to the color. The user can also select a color by entering a color value in the color display control. The color palette tab page 24 also includes a color palette selection control. The user can switch the color combination of the color selection controls displayed on the color palette tab page 24 by clicking the color palette selection control. The candidate palette colors in the color palette selection control are preset color combinations or user-defined color combinations.

[0516] As Figure 13As shown, when the user chooses to enter the color palette tab 25, the color wheel control 30, the brightness control 31, and the color selection operation control corresponding to the color wheel control 30 and the color selection operation control corresponding to the brightness control 31 are displayed. The color wheel control 30 is an RGB color wheel or an RYB color wheel, that is, a color selection interval obtained by mixing red, green, and blue or red, yellow, and blue as primary colors. The brightness control 31 is used to indicate the intensity of the color brightness. The brightness change displayed by the brightness control 31 is that the brightness increases from bottom to top, that is, gradually transitions from black to white, and the brightness decreases from left to right, that is, gradually changes from white to black. When the user performs a color selection operation on the color wheel control 30, the brightness control 31 displays the brightness change information corresponding to the color selected in the color wheel control. The color display control in the color determination area 29 will also change to a color consistent with the color corresponding to the color selection operation control and the color value corresponding to the color. The user can also select a color by entering a color value in the color display control.

[0517] If Figure 14 As shown in FIG. 2 , when the user chooses to enter the history tab page 26, a color selection operation control corresponding to at least one candidate color is displayed. Whenever the user triggers the color determination control in the color determination area 29, the color will be stored in the history tab page, and the earlier the color is selected, the lower the ranking. The user can also switch the displayed candidate colors by sliding.

[0518] 2. Set up particle map

[0519] If Figure 15 As shown in FIG. 1 , the appearance area 16 further includes a particle map selection area 32, which includes at least one candidate particle map control, and different particle map controls correspond to different particle maps. The particle map selection area 32 also includes a currently selected particle map display icon, which is used to indicate the particle map corresponding to the particle generated by the current particle generator. The particle map selection area 32 can collapse at least one candidate particle map control in the particle map selection area 32 by triggering a particle map collapse control.

[0520] In some embodiments, the user can add a custom particle texture component to the texture selection area by importing a texture.

[0521] If Figure 16 As shown in FIG. 1 , the detail area 14 further includes a special effect parameter area 33, which is used to set the property parameters of the particles generated by the particle generator. The special effect parameter area 33 can collapse at least one property setting control in the special effect parameter area 33 by triggering the special effect parameter collapse control.

[0522] Different property parameters correspond to different property setting controls. Different property parameters have different setting methods, which include the following three methods: ​​​​​​

[0523] Setting method 1: Set property parameters based on keyframe controls;

[0524] Setting method 2: Set the property parameter range based on the maximum value control and / or minimum value control;

[0525] Setting method 3: Directly set property parameters.

[0526] The above particle texture map also belongs to a type of property parameter, and the setting method adopted is setting method 3. The property parameters of the particles and their corresponding setting methods will be introduced one by one below.

[0527] 3. Set the loop period of the particles (loop period) (setting method 3)

[0528] The loop period is the lifespan of the particles, which is used to indicate the existence time of the particles generated by the particle generator, that is, the time from the generation to the disappearance of the particles generated by the particle generator.

[0529] As Figure 16 shown, the special effect parameter area 33 includes a loop period setting control 34. The user can manually enter a number by clicking on the loop period input box to set the loop period of the particles; the user can also set the loop period of the particles by dragging the loop period property bar. After clicking on the loop period input box, the input method application program will be called to input the loop period; or, as Figure 17 shown, an input control 35 is displayed on the editor interface 10 to input the loop period. The loop period corresponding to the loop period input box and the loop period property bar is the same. When the loop period of the particle generator is changed through the loop period input box, the length displayed by the loop period property bar will also change correspondingly; similarly, when the loop period of the particle generator is changed through the loop period property bar, the value displayed by the loop period input box will also change correspondingly.

[0530] In some embodiments, the loop period set through the loop period setting control 34 is the maximum loop period of the particles generated by the particle generator. For example, if the loop period set by the loop period setting control 34 is 5, then the loop period of the particles generated by this particle generator is a random value in (0, 5], for example, the particle generator generates particles a1 to a5, and the corresponding loop periods of particles a1 to a5 are 2, 4, 3, 2, 5 respectively.

[0531] 4. Set the particle color (setting method 1)

[0532] The user can control the color change of the particles generated by the particle generator during its loop period by setting the particle color.

[0533] As Figure 16As shown, the special effect parameter area 33 further includes a particle color setting entry 36. The particle color setting entry 36 displays a particle color preview control, which is used to indicate the color change of the particles generated by the particle generator during the cycle.

[0534] As Figure 18 shown, after the user clicks on the particle color setting entry 36, a particle color setting area 37 is displayed. The user can set the color change of the particles generated by the particle generator during the cycle through the particle color setting area 37. The particle color setting area 37 includes at least two color keyframe controls, a color coordinate axis 38, at least one of a keyframe addition control 39, a keyframe deletion control 40, a color wheel control 41, and a brightness control 42. The particle color initially includes two keyframe controls, namely a start frame control 43 and an end frame control 44. At least two keyframe controls included in the particle color are located in the color coordinate axis. The start frame control 43 is located at the leftmost side of the color coordinate axis, and the end frame control 44 is located at the rightmost side of the color coordinate axis.

[0535] The user can add a keyframe control in the color coordinate axis 38 by clicking on the keyframe addition control 39. The newly added keyframe control is located between the selected keyframe control and the first keyframe control on the right side of the keyframe control. As Figure 19 shown, in schematic diagram (1), the color coordinate axis includes a start frame control 43 and an end frame control 44. As Figure 19 shown in schematic diagram (2), the selected keyframe control is the start frame control 43. After the user clicks on the keyframe addition control, a new keyframe control 45 is added between the start frame control 43 and the end frame control 44. As Figure 19 shown in schematic diagram (3), the selected keyframe control is still the start frame control 43. After the user clicks on the keyframe addition control, a new keyframe control 46 is added between the start frame control 43 and the keyframe control 45. As Figure 19 shown in schematic diagram (4), the keyframe control 45 is selected. After the user clicks on the keyframe addition control, a new keyframe control 47 is added between the keyframe control 45 and the end frame control 44. When adding a new keyframe control between two keyframe controls, the new keyframe control is located at the midpoint of the two keyframe controls. The color coordinate axis 38 can include at most 5 keyframe controls. When the number of keyframe controls in the color coordinate axis 38 reaches 5, continuing to click on the keyframe addition control 39 will display a prompt message "The current number of keyframes has reached the maximum, and further addition is prohibited" in the editor interface.

[0536] As Figure 18As shown, the user can delete the selected keyframe control in the color coordinate axis 38 by clicking the keyframe deletion control 40. Among them, the start frame control 43 and the end frame control 44 cannot be deleted. When the user operates to delete the start frame control 43 or the end frame control 44, a prompt message "Deletion of the start frame is prohibited" or "Deletion of the end frame is prohibited" will be displayed on the editor interface.

[0537] It should be noted that the keyframe controls other than the start frame control 43 and the end frame control 44 can be moved on the color keyframe 38 to change their positions. As Figure 19 shown in the schematic diagram (5), after the keyframe control 45 is selected, it is moved to the left.

[0538] As Figure 18 shown, the particle color setting area 37 includes a color wheel control 41, a brightness control 42, and a color selection operation control corresponding to the color wheel control 41 and a color selection operation control corresponding to the brightness control 42. The color wheel control 41 is an RGB color wheel or an RYB color wheel, that is, a color selection range obtained by mixing red, green, and blue or red, yellow, and blue as primary colors respectively. The brightness control 42 is used to indicate the intensity of the color brightness. The brightness change shown by the brightness control 42 is that the brightness increases from bottom to top, that is, gradually transitions from black to white, and the brightness decreases from left to right, that is, gradually changes from white to black. When the user performs a color selection operation on the color wheel control 41, the brightness control 42 displays the brightness change information corresponding to the color selected in the color wheel control. The user selects the keyframe control 43 on the color coordinate axis 38, and selects the desired color by adjusting the color wheel control 41 and the brightness control 42, and adds this color to the selected keyframe control 43. The color coordinate axis 38 will display a gradient color that gradually changes from the color corresponding to the keyframe control 43 to the color corresponding to the keyframe control 44. In the case where the color coordinate axis includes more than two keyframe controls, as Figure 9 shown in the schematic Figure 3 diagram, the color coordinate axis 38 will display a gradient color that gradually changes one by one from the color corresponding to the keyframe control 43, the color corresponding to the keyframe control 46, the color corresponding to the keyframe control 45 to the color corresponding to the keyframe control 44.

[0539] As Figure 18 shown, the particle color setting area 37 also includes a color reset control 48. After the user clicks the color reset control 48, the color displayed in the color coordinate axis 38 returns to the state when first entering the particle color setting area 37; or, after the user clicks the color reset control 48, the color displayed in the color coordinate axis 38 changes to the color corresponding to the selected keyframe control.

[0540] As Figure 18As shown, the particle color setting area 37 further includes a color display control, which is used to display the currently selected color and its corresponding color value. The user can also select a color by entering a color value in the color display control.

[0541] It should be noted that the color selection operation for the particle color can also adopt any one of the color selection operations for the base as described in Figures 12 to 14 , that is, the particle color setting area 37 includes a color selection tab page, and the color selection tab page includes at least one of a color palette tab page, a color palette tab page, and a history tab page.

[0542] 5. Set the emission shape (emission position) (setting method 2)

[0543] Figure 20 The figure shows a schematic diagram of the UGC special effect generation method in the game program provided by an exemplary embodiment of the present application.

[0544] The emission position is used to indicate the initial position of the particles generated by the particle generator, and the emission position can also be called the emission shape. After the user clicks on the emission position entry 49, at least one emission position control is displayed. The emission position control includes a cylinder parameter control 50, a triangle parameter control 51, a sphere parameter control 52, and a custom parameter control 53.

[0545] As Figure 21 shown in the schematic diagram (1), when the user selects the cylinder parameter control 50, the particles generated by the particle generator are on the surface and inside the cylinder; as Figure 21 shown in the schematic diagram (2), when the user selects the triangle parameter control 51, the particles are on the surface and inside the triangular prism; as Figure 21 shown in the schematic diagram (3), when the user selects the sphere parameter control 51, the particles are on the surface and inside the sphere.

[0546] When the user selects the custom parameter control 53, the editor interface displays the custom parameter control, which includes at least one of an x-axis maximum value setting control 54, an x-axis minimum value setting control 55, a y-axis maximum value setting control 56, a y-axis minimum value setting control 57, a z-axis maximum value setting control, and a z-axis minimum value setting control.

[0547] The manifestation form of the emission position of the particles is (x, y, z), and the user can respectively set the maximum and minimum values of x, y, and z. The generation position of the particles will be randomly generated within the area set by the user.

[0548] 6. Set the particle transparency (setting method 1)

[0549] The transparency parameter is used to indicate the transparency of the particles generated by the particle generator during the cycle. The value range of the transparency parameter is from 0 to 1. When the transparency is 0, the particles are displayed as completely opaque; when the transparency is 1, the particles are displayed as completely transparent.

[0550] As Figure 22 shown, the special effect parameter area 33 further includes a transparency setting entry 59. The transparency setting entry 59 also displays the current set transparency trend. After clicking on the transparency setting entry 59, the transparency setting area 60 is entered. As Figure 23 shown, the transparency setting area 60 includes a transparency coordinate system 61 and at least two transparency key frame controls 62 located in the transparency coordinate system 61. The user can set the transparency change trend by dragging the transparency key frame controls.

[0551] The way for the user to operate the transparency key frames and adjust the transparency parameter is similar to that of adjusting the particle color described above, and will not be elaborated here.

[0552] 7. Set the particle brightness (Setting method 1)

[0553] The brightness parameter is used to indicate the brightness of the particles generated by the particle generator during the cycle. The value of the brightness parameter can be negative. When the absolute value of the brightness parameter value is larger and negative, the particles are displayed darker, that is, closer to black; when the brightness parameter value is 0, no brightness is added to the particles, and the particle color is directly displayed; when the brightness parameter is a larger positive value, the particles are displayed brighter.

[0554] In some embodiments, the upper limit of the brightness parameter is a preset value. Exemplarily, the upper limit of the brightness parameter is 10.

[0555] In some embodiments, the lower limit of the brightness parameter is a preset value. Exemplarily, the upper limit of the brightness parameter is -10.

[0556] The special effect parameter area 33 further includes a brightness setting entry 58. The brightness setting entry 58 also displays the current set brightness trend. After clicking on the brightness setting entry 58, the brightness setting area is entered. The brightness setting area is as Figure 5 shown in the schematic diagram (3), which will not be elaborated here.

[0557] 8. Set the particle scaling parameter (Setting method 1)

[0558] The scaling parameter of the particles is similar to the transparency and brightness. The scaling parameter is used to indicate the degree of scaling of the particles generated by the particle generator during the cycle period, and this degree of scaling is used to indicate the scaling ratio relative to the default particle size. The minimum value of the particle scaling parameter is 0. When the particle scaling parameter is 0, the particle size is 0 times the default particle size; when the particle scaling parameter is 1, the particle size is 1 times the default particle size; when the particle scaling parameter is 2.5, the particle size is 2.5 times the default particle size.

[0559] As Figure 22 shown, the special effect parameter area 33 further includes a scaling setting entry 60. After clicking on the scaling setting entry, the scaling setting area is entered. The scaling setting area is as shown in the schematic diagram (1) of Figure 5 and will not be elaborated here.

[0560] 9. Set the particle generation speed (Setting method three)

[0561] The particle generation speed is used to indicate the number of particles generated by the particle generator per unit time. The unit time is a preset value; or, the unit time is a value set by the user.

[0562] Exemplarily, the unit time is 1 second, and the generation rate is used to indicate the number of particles generated by the particle generator within 1 second; or, the unit time is a value of 20 seconds set by the user, and the generation rate is used to indicate the number of particles generated by the particle generator within 20 seconds.

[0563] 10. Set the particle emission speed (Setting method two)

[0564] The manifestation form of the particle emission speed is (x, y, z), which is used to indicate the initial speed of the particles in different directions. The emission speed includes at least one of the x-axis emission speed, the y-axis emission speed, and the z-axis emission speed. When setting the particle emission speed, the speed range in different directions can be set. For example, the speed range in the x-axis direction is set to [-10, 20], that is, the generated particles will randomly have a speed with a maximum value of 10 in the negative half-axis direction of the x-axis and a minimum value of 0, and a speed with a maximum value of 20 and a minimum value of 0 in the positive half-axis direction of the x-axis.

[0565] 11. Set the particle acceleration (Setting method two)

[0566] The manifestation form of the particle acceleration is (x, y, z), which is used to indicate the acceleration of the particles of the particle generator. The acceleration includes at least one of the x-axis acceleration, the y-axis acceleration, and the z-axis acceleration. The user can set the acceleration in different directions.

[0567] When the x-axis acceleration of the particle is positive, the acceleration direction is the positive half-axis direction of the x-axis; when the x-axis acceleration of the particle is negative, the acceleration direction is the negative half-axis direction of the x-axis; when the y-axis acceleration of the particle is positive, the acceleration direction is the positive half-axis direction of the y-axis; when the y-axis acceleration of the particle is negative, the acceleration direction is the negative half-axis direction of the y-axis; when the z-axis acceleration of the particle is positive, the acceleration direction is the positive half-axis direction of the z-axis; when the z-axis acceleration of the particle is negative, the acceleration direction is the negative half-axis direction of the z-axis.

[0568] 12. Set particle rotation parameters (Setting method 2)

[0569] The rotation parameter can also be called the rotation angle. The particle rotation parameter is used to indicate the initial rotation angle of the particle. The user can set the random value of the initial rotation angle of the particle by specifying the maximum and minimum values of the rotation parameter.

[0570] The rotation angle is the rotation angle relative to the preset posture of the particle. The value range of the rotation angle is [0, 360]; or, the value range of the rotation angle is [-180, 180]. Exemplarily, when the value range of the rotation angle is [0, 360] and the rotation angle of the particle is 120 degrees, the particle rotates 120 degrees clockwise or counterclockwise relative to the preset posture of the particle; or, when the value range of the rotation angle is [-180, 180] and the rotation angle of the particle is 120 degrees, the particle rotates 120 degrees clockwise or counterclockwise relative to the preset posture of the particle; when the rotation angle of the particle is -60 degrees, the particle rotates 60 degrees counterclockwise or clockwise relative to the preset posture of the particle.

[0571] 13. Set particle rotation rate (Setting method 2)

[0572] The rotation rate can also be called the rotation speed. The particle rotation rate is used to indicate the angular velocity of the particle. The user can set the random value of the angular velocity of the particle by specifying the maximum and minimum values of the rotation rate.

[0573] · Add signal control to the particle generator

[0574] The user can add a control signal to the particle generator to control the particle emission of the particle generator. Such as Figure 24As shown, the user can set control signals in the special effect preset area 64 of the basic area 63. The control signals include an automatically generated signal, an open signal, and a close signal, and different signals correspond to different controls respectively. The automatic play control 65 corresponds to the automatically generated signal and can only set to turn on or turn off the automatic generation. The open signal control 66 corresponds to the open signal, and the close signal control 67 corresponds to the close signal. The open signal is used to instruct the particle generator to start generating particles; the close signal is used to instruct the particle generator to stop generating particles. For example, set the particle generator not to play automatically, and then set an open signal for the particle generator, and the particle generator can generate particles only when the open signal is triggered; or, set the particle generator not to play automatically, set an open signal and a close signal for the particle generator, and the generation of particles can be freely controlled by triggering the open signal and the close signal of the particle generator; or, set the particle generator to play automatically, and set a close signal for the particle generator, and the generation of particles can be stopped when the close signal is triggered.

[0575] After setting the control signal, a corresponding signal trigger or signal trigger control needs to be set to trigger the control signal. For example, the signal trigger includes an induction switch. The signal control area of the induction switch is as Figure 25As shown, in the switch base area 68 of the induction switch, a component selection control 69, a switch-on trigger signal 70, and a switch-off trigger signal 71 are displayed. For example, when both the turn-on signal control 66 and the switch-on trigger signal 70 are set to "special effect start", and both the turn-off signal control 67 and the switch-off trigger signal 71 are set to "special effect off", by selecting a character class and a motion component class through the component selection control 69, when a component of the character class or the motion component class triggers the induction signal, the induction switch switches to the "on" state, and the corresponding particle generator starts generating particles. When a user designs a virtual environment using the UGC editor, the components provided by the UGC editor can be adopted. The components include at least one of various virtual objects pre-designed by developers, virtual objects designed and saved by users, basic components for designing virtual objects, and virtual characters for interaction. The components can also be referred to as components. The virtual object is, for example, a virtual tree or a virtual rock. The basic components are, for example, a cuboid, a cube, a sphere, a cylinder, etc. The virtual character can be a virtual character controlled by a player, a virtual character generated by a game program with interaction logic, or a virtual character without interaction logic. When the virtual character has no interaction logic, it can be regarded as a virtual object. The components that can trigger the induction switch include a character class, a motion component class, a physical component class, and a specified component. Among them, the character class is a virtual character controlled by a player or a virtual character existing in the virtual environment; the motion component class is a component with a motion mode set. After the component has a motion mode set, it will move in the virtual environment based on the motion logic corresponding to the motion mode; the physical component class is a component with physical properties added, for example, physical properties such as gravity and flammability are added to the component. Using this type of component can simulate the effects in the real environment in the virtual environment. For example, two sphere components are placed at a high place in the virtual environment at the same time. One sphere has gravity added, and the other sphere has no gravity added. When starting to play, the object with gravity added will fall freely, while the object without gravity added will still float in place; the specified component is a component or component type set by the user that can trigger the induction switch, for example, adding a component number that can trigger the induction switch to the induction switch.

[0576] · Add motion control to the particle generator

[0577] The user can set a motion unit mode for the particle generator to control the motion mode of the particle generator.

[0578] The motion unit mode includes at least one of a full-scale motion mode, a one-way displacement mode, a cyclic displacement, a one-way rotation mode, a swinging motion mode, and a waypoint motion mode.

[0579] For different motion unit modes, different motion attributes can be set.

[0580] Among them, the waypoint motion mode is used to indicate that a virtual object moves along a motion path formed by at least two waypoints. The positions, rotations, and scales of the at least two waypoints are the same or different. A waypoint is used to indicate at least one of the position, rotation, and scale of the virtual object when the virtual object moves to that waypoint; the one-way displacement mode is used to indicate a single uniform motion in a straight line, and it will stop after the motion ends. The user can set the motion duration of the single motion, etc. to control the single motion; the cyclic displacement is used to indicate a uniform reciprocating motion on the same straight line; the one-way rotation mode is used to indicate that the virtual object performs a uniform rotation motion with an unchanged axis, and the axis is the center of the virtual object; the swinging motion mode is used to indicate a rotational swing with an unchanged axis, such as a pendulum, etc.; the full motion mode is used to indicate motion according to the motion logic. In the full motion mode, all motion performances can be achieved through settings, such as at least one of the above one-way displacement mode, cyclic displacement, one-way rotation mode, and swinging motion mode. The full motion mode can also set variable-speed motion, etc.

[0581] In some embodiments, the particle generator includes at least one of a particle parameter editor, a particle signal manager, a particle parameter random manager, and a particle parameter keyframe manager.

[0582] The particle parameter editor is used to implement graphical editing of the attribute parameters of particles; the particle signal manager is used to add control signals to the particle generator; the particle parameter random manager is used to make the attribute parameter values of particles conform to the attribute parameter intervals set by the user; the particle parameter keyframe manager is used to support setting particle attribute parameters using keyframes, and when particles are generated, make the particle attributes conform to the attribute parameter requirements set by the keyframes.

[0583] In some embodiments, when the user sets a control signal for the particle generator, a particle signal manager is attached to the particle generator, enabling the particle generator to receive the corresponding control signal and realizing the opening or closing of the particle generator controlled by the control signal.

[0584] In some embodiments, when the particle generator does not have a particle parameter random manager, a particle parameter random manager is added to the particle generator. When the attribute parameter interval corresponding to the attribute parameter T is modified, the corresponding maximum value Max is uploaded. <t>and the minimum value Min <t>To the particle parameter random manager, the particle parameter random manager sets the maximum value Max according to the type of the attribute parameter T and the attribute parameter variable corresponding to the attribute parameter T <t>and minimum value Min <t>。

[0585] In some embodiments, when the particle generator does not have a particle parameter random manager, a particle parameter keyframe manager is added to the particle generator. The keyframe K includes a keyframe time T and an attribute parameter value V. All keyframes of each attribute parameter are saved in the keyframe array Array <k>Among them, the array is arranged in ascending order of time. When obtaining the attribute parameters corresponding to RT at a certain moment, the RT at this moment is used in the key frame array Array <k>Find the previous key frame K0 and the next key frame K1 corresponding to RT at that moment. Binary search, interpolation search and other search methods can be used to optimize the search efficiency during the search. After finding the previous key frame K0 and the next key frame K1, calculate the attribute parameter value corresponding to RT through interpolation. The interpolation formula is as follows.

[0586] RV = K0.V + (K1.V - K0.V) * ((RT - K0.T) / (K1.T - K0.T))

[0587] Among them, RV represents the attribute parameter value corresponding to the RT moment; K0.V represents the attribute parameter value corresponding to the previous key frame K0; K1.V represents the attribute parameter value corresponding to the next key frame K1; RT represents a known moment; K0.T represents the key frame moment corresponding to the previous key frame K0; K1.T represents the key frame moment corresponding to the next key frame K1.

[0588] Figure 26 The flowchart of the UGC special effect generation method in the game program provided by an exemplary embodiment of the present application is shown. This method is executed by a computer device, and the computer device can be a terminal device or a server such as Figure 1 or Figure 2 The method includes:

[0589] Step 1001: Parameter editing.

[0590] In some embodiments, the user edits the attribute parameters of the particle generator using the above method. According to different editing methods, parameter editing includes basic editing, range editing and key frame editing. Basic editing corresponds to the above setting method 1, directly setting the attribute parameters; range editing corresponds to the above setting method 2, setting the attribute parameters based on the attribute parameter interval; key frame editing corresponds to the above setting method 1, setting the attribute parameters based on the key frame.

[0591] Step 1002: Data saving.

[0592] In some embodiments, in response to the user's save operation on the attribute parameters, save the attribute parameters; or, in response to the user's save operation on the map data, save the map data and the attribute parameters of the particle generators existing in the map.

[0593] Step 1003: Parameter serialization.

[0594] In some embodiments, the computer device serializes the saved parameters. Exemplarily, the terminal device serializes the saved attribute parameters; or, the terminal device extracts the attribute parameters of the particle generators protected in the map data and serializes the attribute parameters.

[0595] Step 1004: Save the parameters of a single particle generator to the corresponding Actor.

[0596] In some embodiments, the attribute parameters of each particle generator are saved to the corresponding Actor. An Actor is a basic type of game object in a game engine, and any virtual object that can be added to a virtual environment needs to inherit from the Actor class. It can be understood that the Actor class is the base class for all virtual objects that can be added to a virtual environment.

[0597] Step 1005: Save all particle actor data to the corresponding map.

[0598] In some embodiments, all particle Actor data is saved to the map corresponding to the particle generator. A particle Actor is used to indicate the Actor corresponding to each particle generator, and the attribute parameters of the particle generator are saved in this Actor.

[0599] Step 1006: Write the map data to the database.

[0600] In some embodiments, the server writes the map data to the database, and the map data is uploaded by the terminal device. Optionally, the map data includes the map corresponding to the particle generator, and each particle generator added to the map and its attribute parameters are saved in this map.

[0601] In summary, the method provided by the embodiments of the present application shows that when saving map data, the particle generator and its corresponding attribute parameters are also saved together with the map data, so that the saved effect can also be achieved during subsequent editing or playing.

[0602] Figure 27 Shows a flowchart of a UGC special effect generation method in a game program provided by an exemplary embodiment of the present application. This method is executed by a terminal device, and the terminal device can be a terminal device such as Figure 1 or Figure 2 The terminal device in, and the method includes:

[0603] Step 1010: Parameter deserialization.

[0604] In some embodiments, the terminal device receives the map data transmitted by the server, extracts the map corresponding to the particle generator from the map data, extracts each particle generator and its corresponding attribute parameters in the map one by one, and deserializes the attribute parameters to obtain the deserialized attribute parameters.

[0605] Step 1011: Dynamically create attributes according to the deserialized parameters.

[0606] In some embodiments, the terminal device dynamically creates a particle generator instance according to the deserialized parameters, that is, instantiates the particle generator.

[0607] Step 1012: Initialize the particle component data.

[0608] In some embodiments, the particle generator is initialized based on the attribute parameters, and the attribute parameter values or attribute parameter ranges of the respective attribute parameters are obtained.

[0609] Step 1013: Determine whether to play automatically.

[0610] In some embodiments, it is determined whether the particle generator is set with an automatic generation signal. If so, step 1021 is executed; if not, step 1014 is executed.

[0611] Step 1014: Set the particle to the inactive state.

[0612] In some embodiments, the particle generator is not set with an automatic generation signal, that is, it does not play automatically, and the particle generator is set to the inactive state.

[0613] Step 1015: Determine whether there is a control signal.

[0614] In some embodiments, it is determined whether there is a control signal. If a control signal exists, step 1016 is executed; if no control signal exists, it is proved that the particle generator can neither play automatically nor generate particles according to the control signal, and the particle generator is invalid, and the calculation of the particle generator is ended.

[0615] Step 1016: Create a signal receiving component.

[0616] In some embodiments, in the presence of a control signal, a signal receiving component is created, and the signal receiving component is used to receive signal input.

[0617] Step 1017: Wait for signal input.

[0618] In some embodiments, wait for signal input. When a signal input is received, step 1018 is executed; otherwise, wait for signal input until the particle generator is deleted.

[0619] Step 1018: Signal input.

[0620] Step 1019: Determine whether it is an open signal.

[0621] In some embodiments, it is determined whether the input signal is an open signal. If so, step 1021 is executed; if not, step 1020 is executed.

[0622] Step 1020: Set the particle to the inactive state.

[0623] In some embodiments, the particle generator is kept in an inactive state.

[0624] Step 1021: Set the particle to an active state.

[0625] In some embodiments, setting the particle generator to an active state means starting to generate particles.

[0626] Step 1022: Create a corresponding manager for the parameter.

[0627] In some embodiments, corresponding managers are created according to different attribute parameters.

[0628] Step 1023: The manager updates the parameter.

[0629] In some embodiments, the attribute parameter values of the particles generated by the particle generator are updated based on the manager Tick.

[0630] In summary, the method provided by the embodiments of the present application shows a method for a terminal device to obtain a particle generator according to previously saved data and manage the particle generator during the running of a game program when performing virtual environment editing or playing in a virtual environment. This method ensures the implementation of the particle generator and the signal control function.
