[0023] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the present application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative effort fall within the protection scope of the present application.
[0024] At present, special effects in game characters are usually hung on the characters by art workers, and the special effects are oriented in advance, usually in a certain direction, and the special effect orientation cannot be changed with the character orientation. On the other hand, the special effects can also be hung by program workers, but the hung special effects are not convenient to modify and debug, and need repeated communication and modification between art workers and program workers, which increases the communication and time cost.
[0025] Based on the above, the embodiments of the present application provide a particle animation effect control method, device and electronic device, which can be applied to game engines and animation film and television engines, and used in games or other three-dimensional scenes for particle animation effect control and display.
[0026] In order to facilitate the understanding of the present embodiment, first, a particle animation effect control method disclosed by the present embodiment will be introduced in detail, as shown in the figure, the method comprises: Figure 1
[0027] Step S102, receiving a release instruction of a virtual character releasing a target particle animation effect;
[0028] In games and other virtual scenes, virtual characters are created by constructing three-dimensional models. The game world includes various elements such as environment, virtual characters, NPC (Non-Player Character), etc., and each virtual character has its specific identity and unique skills. When using skills, it will be accompanied by the release of animation effects. Animation effects include: sequence frame animation effects, skeletal animation effects, and particle animation effects, etc. Among them, the effects realized by sequence frame animation and skeletal animation are similar, while particle animation effects are generally used for special effects, such as fire, flash, etc. Particle animation effects can be specific light effects in a virtual world, which consist of an emitter, an effector, and a destroyer. The emitter can be bound to a virtual object and move with the virtual object while emitting particles; the effector acts on the emitted particles and can affect the color, brightness, position, and other attributes of the particles; the destroyer is responsible for destroying the particles.
[0029] In an implementation manner, when a user clicks on a specified operation position corresponding to a skill, the system receives a release instruction of a virtual character releasing a target particle animation effect, and after receiving the release instruction, the system releases the animation effect of the target particle based on a preset particle animation effect. In the game world, the user controls the virtual character to participate in the plot task and interact with the NPC. Since each virtual character has a different identity or character, the skills they have are also different. Usually, each skill corresponds to at least one animation effect, and when the user uses a certain skill, the virtual character will release the animation effect of the skill, providing the user with a better visual experience.
[0030] Step S104, determining particle orientation information of the target particle animation effect based on the first position information of the virtual character and specified position information of a virtual camera corresponding to the virtual character; wherein the specified position information includes specified position information of a position having a specified distance from the virtual camera in a specified direction;
[0031] In all scenes, each object carries a transformation matrix to record its position and orientation information. When a point is first defined in a scene, its coordinates are defined in the world space, and the coordinates of the point are defined relative to the global or world Cartesian coordinate system. The coordinate system has an origin with coordinates [0, 0, 0], and the coordinates of any point defined in the space are defined relative to the origin. The world coordinate system is a convention for defining the coordinates [0, 0, 0] and three unit axes orthogonal to each other in a 3D virtual space, which is a reference for measuring any other point or any other arbitrary coordinate system.
[0032] The virtual camera shoots in the world space, and the obtained scene picture is displayed on the terminal device. The user observes the scene in the world space through the virtual camera. The virtual camera is equivalent to the eyes of the user, and controls the position of the view point of the user and the size of the view of the user. In the third-person game, the virtual camera is located at a certain position behind the virtual character. In the scene picture, the shadow of the virtual character is displayed, that is, the position of the view point of the user is placed at a certain distance behind the virtual character. The game that needs to be observed globally places the position of the view point of the user at a very high position from the ground.
[0033] In a specific implementation manner, when the virtual character issues the release instruction, the position information of the virtual character in the game world space, that is, the first position information, can be obtained from the change matrix of the virtual character.
[0034] In the general third-person game, the virtual camera keeps a certain distance from the virtual character, and the virtual camera is always aimed at the virtual character played by the user. Therefore, the orientation of the virtual camera is associated with the orientation of the virtual character. The specified position information of the virtual camera corresponding to the virtual character can be determined based on the position and the orientation of the virtual camera. It should be noted that if the position information of the virtual camera is referred to when the particle orientation information is determined, because the virtual camera has multiple orientations at the same position, the single position information of the virtual camera cannot indicate the orientation of the virtual character, which may cause the obtained particle orientation information to be inconsistent with the orientation of the virtual character. The specified position information includes a position having a specified distance from the virtual camera in a specified direction. The specified direction can be related to the orientation of the virtual camera, for example, the specified direction has a certain angle with the orientation direction of the virtual camera, or the specified direction is the orientation of the virtual camera. In this way, the obtained particle orientation can be matched with the orientation of the virtual character.
[0035] After the first position information of the virtual character and the specified position information of the virtual character and the corresponding virtual camera are determined, the first position information and the specified position information are subjected to matrix operation or vector operation to obtain the particle orientation information.
[0036] In step S106, the target particle animation effect is controlled based on the particle orientation information.
[0037] When the target particle animation effect is released, the particle orientation information can control the release direction of the target particle, so that the release direction of the target particle is matched with the particle orientation information. In addition, other control parameters can be set, for example, the color, distance, display duration, etc. of the particle release, so as to accurately control the display effect of the target particle animation.
[0038] The control method of the particle animation effect receives a release instruction of a virtual character releasing a target particle animation effect; determines particle orientation information of the target particle animation effect based on first position information of the virtual character and specified position information of a virtual camera corresponding to the virtual character; wherein the specified position information includes specified position information of a position having a specified distance from the virtual camera in a specified direction; and controls the release of the target particle animation effect based on the particle orientation information. In this way, the particle orientation is determined based on relevant parameters of the virtual character and the virtual camera, and the particle animation is released based on the particle orientation; the direction of the release of the particle animation can be controlled to match the orientation of the virtual character and to change with the orientation of the virtual character, thereby improving the realism of the particle animation effect and improving the visual experience of the user.
[0039] The following embodiments provide a specific implementation of determining particle orientation information.
[0040] Specifically, the front direction information of the target particle animation effect is determined based on the first position information of the virtual character and the specified position information of the virtual camera corresponding to the virtual character; wherein the front direction information includes direction information of a front direction based on the orientation of the target particle animation effect; and the particle orientation information of the target particle animation effect is determined based on the front direction information.
[0041] The first position information of the virtual character and the specified position information of the virtual camera corresponding to the virtual character can be obtained through a transformation matrix carried by the virtual character and the virtual camera in a game world space; each object carries a transformation matrix in all scenes in the game world space, and the position vector and the orientation information of the object in the world space can be obtained through the transformation matrix. In actual implementation, the front direction information of the target particle animation effect can be obtained by subtracting the vector corresponding to the first position information of the virtual character from the specified position information of the virtual camera. The front direction information includes direction information of a front direction based on the orientation of the target particle animation effect.
[0042] Based on the above-obtained front direction information, the right direction vector and the upper direction vector of the target particle orientation can be obtained through cross product operation in sequence, and finally the three direction vectors are normalized and combined to determine the particle orientation information of the target particle animation effect.
[0043] The following embodiments provide a specific implementation of determining the front direction of the target particle animation effect.
[0044] Specifically, the specified position information of a position having a specified distance from the virtual camera in the orientation direction of the virtual camera is determined; and the front direction information of the target particle animation effect is determined based on the specified position information and the first position information of the virtual character.
[0045] In the manner, the specified direction in the specified position information of the virtual camera is specifically a direction of the virtual camera, and a position is obtained along the direction, the position has the specified distance from the virtual setting, and the position is the specified position; the specified position information is position information of the specified position in the world space.
[0046] Generally, the virtual camera can have multiple directions, for example, in a situation, the virtual character stands in the front direction, when the virtual camera is in the front direction, the user can see the back of the virtual character and information in front of the virtual character, when the virtual camera is in the downward direction, the user can observe the virtual character from above, and when the virtual camera is in the left direction, the user can observe the information on the right side of the virtual character.
[0047] The above embodiment provides a front direction information of a target particle animation effect, and the following embodiment will provide a particle direction information of the target particle animation effect based on the front direction information.
[0048] Specifically, the front direction information and the preset upward direction information are cross product operated to obtain right direction information of the target particle animation effect; the right direction information includes direction information of the right side direction based on the direction of the target particle animation effect; the front direction information, the right direction information and the preset upward direction information are determined as the particle direction information of the target particle animation effect.
[0049] Based on the obtained front direction information of the target particle animation effect, the right direction information of the target particle animation effect can be obtained through cross product operation. Specifically, when performing vector operation, the front direction information can be expressed in the form of a front direction vector, and the upward direction information can be expressed in the form of a vertical direction vector. The front direction vector and the vertical direction vector are cross product operated to obtain a right direction vector of the target particle animation effect; the right direction vector is the right direction information.
[0050] The preset upward direction information can be specifically (0, 0, 1). Then, the front direction information, the right direction information and the upward direction information are normalized to obtain the particle direction of the target particle animation effect, which is expressed by a world space matrix of the target particle as follows:
[0051]
[0052] In the above matrix, R worldis the particle orientation matrix in the world coordinate system, that is, the particle orientation information described above, wherein, in the three-dimensional vector, x represents the front direction of the particle, y represents the right direction of the particle, and z represents the up direction of the particle. Wherein, (x1, x2, x3) is the particle front direction vector, that is, the aforementioned front direction information, (y1, y2, y3) is the particle right direction vector, that is, the aforementioned right direction information, and (z1, z2, z3) is the particle up direction vector, that is, the aforementioned up direction information. Based on this, the particle orientation information of the target particle animation effect can be determined.
[0053] The following embodiments provide an implementation for controlling the release of the target particle animation effect.
[0054] The particle orientation information includes: particle orientation information in a world space coordinate system in which the virtual character is located; obtaining orientation offset information of the virtual character; wherein the orientation offset information includes: orientation offset information of a first orientation of the virtual character in the world space coordinate system and a second orientation of the virtual character in a character model space coordinate system; converting the particle orientation information in the world space coordinate system to particle orientation information in the character model space coordinate system based on the orientation offset information; and controlling the release of the target particle animation effect based on the particle orientation information in the character model space coordinate system.
[0055] Specifically, relative to the character model space, the world space is the outermost parent space in which the character model space is located, and in the world space, the origin is the center of the game space, and the X, Y and Z axes are fixed. Each character model has its own independent coordinate space, and when the character model moves and rotates, the character model space also moves and rotates.
[0056] The particle orientation information is determined based on the position of the virtual character in the world space and the position and orientation of the virtual camera and other factors, so the particle orientation information is information in the world space coordinate system. Since the particle animation effect needs to be attached to the virtual character, in order to facilitate control, the particle orientation information needs to be converted to the character model space. Based on this, the orientation offset information of the virtual character needs to be obtained first, which can be understood as the difference between the orientation of the virtual character in the actual space coordinate system and the orientation of the virtual character in the character module control coordinate system. Specifically, the first orientation of the virtual character in the world space coordinate system is obtained first, which can be obtained from the transformation matrix of the virtual character in the world space, and the second orientation of the virtual character in the character model space coordinate system is obtained, which can be obtained from the transformation matrix of the virtual character in the character model space. As described above, each virtual character carries a transformation matrix to represent the position, orientation and other information of the virtual character in the world space and the character module space.
[0057] Based on the above orientation offset information, the particle orientation information in the world space coordinate system can be converted to the particle orientation information in the character model space, and then the particle orientation information in the character model space coordinate system is obtained. After obtaining the particle orientation information in the character model space coordinate system, the target particle is controlled to release the animation effect. Based on this, the orientation of the target particle can be kept consistent with the orientation of the virtual character, and when the orientation of the virtual character changes, the orientation of the animation effect released by the target particle will also change.
[0058] The following embodiments provide a specific implementation of converting the particle orientation information in the world space coordinate system to the particle orientation information in the character model space coordinate system.
[0059] The particle orientation information in the world space coordinate system, the first orientation of the virtual character in the world space coordinate system, and the orientation offset information are subjected to matrix calculation to obtain the particle orientation information in the character model space coordinate system.
[0060] Specifically, the transformation method of transforming the orientation information in the world space coordinate system to the particle orientation information in the character model space coordinate system is as follows:
[0061] R particle = R offset × R -1 character × R world
[0062] Wherein, R particle is the orientation matrix of the target particle, that is, the above particle orientation information in the character model space coordinate system; R offset is the offset matrix of the orientation in the character model space coordinate system relative to the orientation in the world space coordinate system, that is, the above orientation offset information; R -1 character is the inverse matrix of the first orientation of the virtual character in the world space coordinate system, R world is the particle orientation matrix in the world space coordinate system, that is, the particle orientation information in the world space coordinate system.
[0063] Since a column matrix is used, it is necessary to perform right multiplication operation, that is, R world right multiplies R -1 character An intermediate result is obtained, and the intermediate result is right multiplied by R offset , that is, the orientation matrix of the target particle is obtained.
[0064] The following provides a specific implementation method of controlling the release of the target particle animation effect.
[0065] Specifically, the particle is controlled to release along the direction indicated by the particle orientation information, and the target particle animation effect generated by the particle in the release process is displayed.
[0066] The target particle orientation matrix calculated above determines the attribute of the target particle, and a target particle special effect with the attribute is attached to the virtual character. When the virtual character releases the particle special effect, the orientation of the particle special effect is controlled by the target particle orientation matrix.
[0067] Based on the above, the embodiment provides another specific method for controlling a particle animation effect, as shown in Figure 2 The method includes the following steps:
[0068] In step S202, a release instruction for releasing a target particle animation effect is received.
[0069] In step S204, front direction information of the target particle animation effect is determined according to first position information of the virtual character and specified position information of a virtual camera corresponding to the virtual character. The front direction information includes direction information of a front direction based on an orientation of the target particle animation effect.
[0070] In step S206, particle orientation information of the target particle animation effect is determined based on the front direction information.
[0071] In step S208, orientation offset information of the virtual character is obtained. The orientation offset information includes orientation offset information between a first orientation of the virtual character in a world space coordinate system and a second orientation of the virtual character in a character model space coordinate system.
[0072] In step S210, the particle orientation information in the world space coordinate system is converted to particle orientation information in the character model space coordinate system based on the orientation offset information.
[0073] In step S212, the target particle animation effect is controlled based on the particle orientation information in the character model space coordinate system.
[0074] When the particle special effect is attached to the virtual character, the special effect can be attached using a montage, which is a multifunctional tool that can realize various animation effects, mainly related to animation controls in the public code or blueprint visual script. In the montage notification menu interface, a new AO attachment can be created by right-clicking the notification. After creation, clicking this AO can open detailed parameters. Before opening the detailed parameters, the particle special effect needs to be attached to the interface of the particle special effect. In one way, the particle special effect is attached to the interface of Niagara. In the animation notification panel interface, the particle special effect is added in NiagaraParticle, and then the values of MaxPitch and MinPitch are set to limit the up-down rotation angle, so that it can match the action of the virtual character, so as to achieve the target effect. If the target effect cannot be achieved by setting the value of Pitch, the mixed AO can also be opened, UseLerpwithAO is clicked, and the values of LerpStart and LerpEnd are set to achieve the target effect.
[0075] In the above-mentioned particle animation effect control method, the special effect orientation changes with the character orientation. This method can be applied to the attachment of cascade and niagara particle effects. In the above-mentioned method, the function of changing the particle orientation with the character orientation is added. Specifically, when the particle is played, the position, direction and other parameters of the virtual character and the virtual camera in the world space coordinate system are obtained. Based on these parameters, the particle orientation information in the world space coordinate system is determined, and then the particle orientation information is converted to the character model space coordinate system, so as to attach the particle special effect to the virtual character. Through the above-mentioned way, the virtual object can realize the attachment of the particle special effect with orientation offset without adjusting the particle special effect through the program. At the same time, the staff can also preview and adjust the particle special effect effect in the editor.
