Description

Technical Field

[0001] The present invention relates to the field of game technology, and in particular to a method, device, equipment, medium and program for processing rain special effects in a virtual scene. Background Art

[0002] In order to achieve the effect of an open world in the game, a weather system is essential. However, due to the limitations of machine performance, mobile phones usually use some simpler implementation methods, such as a sequence of frame screen effects of rain, or setting a rain map in a cone that surrounds the rotation of the camera. There are also scripts to control rain particles. Each implementation method has different effects and performance consumption.

[0003] In the existing methods, the screen effects of the rain sequence frames, or the rain map set in a cone that surrounds the lens rotation, these two methods have low performance consumption. However, the effect is average. When the camera rotates, the direction of the rain will not change. For example, the rain is leaning to the right, but after the camera rotates 180 degrees, the rain is still leaning to the right. The visual effect is inconsistent with life experience. The script control is used to form a large number of regional rain particles. This method requires a large number of rain particles to ensure that when the camera position changes, the camera is also under the entire regional rain effect. This rain area needs to include the camera. Because there are many rain particles, they need to be controlled one by one through the script program on the CPU side, which consumes a lot of CPU. Summary of the invention

[0023] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0024] In one embodiment of the present application, a method for processing rain effects in a virtual scene can be run on a local terminal device or a server. When a method for processing rain effects in a virtual scene is run on a server, the method can be implemented and executed based on a cloud interaction system, wherein the cloud interaction system includes a server and a client device.

[0025] In a possible implementation, an embodiment of the present invention provides a method for processing rain special effects in a virtual scene, providing a graphical user interface through a terminal device, the graphical user interface including: a virtual scene, and the virtual scene can be set with rain special effects; wherein the terminal device can be the local terminal device mentioned above, or it can be a client device in the cloud interactive system mentioned above.

[0026] Figure 1 This is a flow chart of a method for processing rain special effects in a virtual scene provided by an embodiment of the present application. Figure 1 As shown, the method includes:

[0027] S101. Determine a target position of a preset rain effect in a virtual scene according to a current position of a virtual camera in a virtual scene and a preset operation mode of the virtual camera.

[0028] Among them, the preset rain special effect is a regional special effect formed by rain particles in a preset area.

[0029] For example, a regional rain particle special effect is freely made using the game engine function to obtain a regional special effect formed by rain particles in a preset area. The shape of the area can be cylindrical or rectangular, that is, the top of the area is a circular or square rain particle emission area, in which the rain particles move down one by one to form a rain effect. The special effect can be a CPU particle special effect or a GPU particle special effect. The size of the special effect area is related to the distance between the special effect and the virtual camera in the virtual scene, and can be adjusted by itself, but it is necessary to ensure that all the pictures in the virtual camera lens are covered by the rain range, and the particle size is adapted to the performance effect of the virtual camera at a distance, so that the user can always see a realistic rain effect. And using the game engine to make rain special effects (for example, game editors such as Unreal Engine and Unity support the production of special effects), supports art engineers to use the game engine function to make freely, does not require program developers to control rain particles one by one, is conducive to development division of labor, and improves development efficiency.

[0030] According to the current position of the virtual camera in the virtual scene and the preset operation mode of the virtual camera, the target position of the virtual camera can be determined. According to the target position of the virtual camera, the target position of the preset rain effect in the virtual scene can be determined so that the preset rain effect always follows the virtual camera.

[0031] S102: Move the preset rain special effect to a target position in the virtual scene.

[0032] Since the target position of the preset rain effect is determined according to the virtual camera, the preset rain effect always moves with the virtual camera and moves to the target position in the virtual scene. During the movement of the virtual camera and the preset rain effect, the virtual camera is close to the preset rain effect, and visually, all the images in the lens of the virtual camera can be covered by the preset rain effect.

[0033] Therefore, it is only necessary to design a small-scale preset rain special effect to achieve the effect of rain in the images captured by the virtual camera, which reduces the number of rain particles, reduces machine performance consumption, and reduces special effects costs.

[0034] In summary, in this embodiment, according to the current position of the virtual camera in the virtual scene and the preset operation mode of the virtual camera, the target position of the preset rain effect in the virtual scene is determined, wherein the preset rain effect is a regional effect formed by rain particles in a preset area; the preset rain effect is moved to the target position in the virtual scene. Therefore, only a small range of preset rain effects need to be designed to achieve the effect of rain in all the images captured by the virtual camera, which reduces the number of rain particles, reduces the machine performance consumption, and reduces the cost of special effects.

[0035] In the above Figure 1 On the basis of the corresponding embodiment, in another embodiment of the present application, determining the target position of the preset rain effect in the virtual scene according to the current position of the virtual camera in the virtual scene and the preset operation mode of the virtual camera in S101 includes:

[0036] If the preset operation mode is the preset trajectory operation mode, the target position is determined from the preset trajectory of the virtual camera according to the current position of the virtual camera.

[0037] The preset track operation mode is a known and determined operation track. When the virtual camera moves on the preset track, the next moving position of the virtual camera is determined as the target position. Thus, the preset rain special effect follows the movement of the virtual camera.

[0038] In summary, in this embodiment, if the preset operation mode is the preset track operation mode, the target position is determined from the preset track of the virtual camera according to the current position of the virtual camera, so that the preset rain effect moves with the virtual camera.

[0039] On the basis of the above embodiment, in another embodiment of the present application, according to the current position of the virtual camera, determining the target position from the preset trajectory of the virtual camera includes:

[0040] According to the current position of the virtual camera and the first preset distance, the target position is determined along the forward direction of the virtual camera and from the preset track of the virtual camera.

[0041] In order to make the rain effect more realistic, a first preset distance is set. When the preset rain effect moves with the virtual camera, the position at the first preset distance from the lens of the virtual camera is determined as the target position. The preset rain effect always maintains the first preset distance from the lens of the virtual camera to prevent the rain effect from sticking to the lens of the virtual camera.

[0042] For example, the first preset distance is preset by a user.

[0043] In summary, in this embodiment, according to the current position of the virtual camera and the first preset distance, the target position is determined from the preset track of the virtual camera along the forward direction of the virtual camera. Thus, by setting the first preset distance, the rain effect is made more realistic.

[0044] Based on the above embodiment, in another embodiment of the present application, according to the current position of the virtual camera and the first preset distance, along the forward direction of the virtual camera, the target position is determined from the preset trajectory of the virtual camera, including:

[0045] At every preset time interval, according to the current position of the virtual camera and the first preset distance, the target position is determined along the forward direction of the virtual camera from the preset track of the virtual camera.

[0046] When the preset rain effect moves with the virtual camera, a position that is a first preset distance away from the lens of the virtual camera is determined as a target position at every preset time interval.

[0047] For example, the preset time interval may be one frame or one second. Determining the target position once at each preset time interval may improve the movement accuracy of the preset rain special effect, thereby making the preset rain special effect more realistic.

[0048] In summary, in this embodiment, at every preset time interval, according to the current position of the virtual camera and the first preset distance, along the forward direction of the virtual camera, the target position is determined from the preset trajectory of the virtual camera. Thus, the movement accuracy of the preset rain special effect is improved, and the preset rain special effect is made more realistic.

[0049] In the above Figure 1 On the basis of the corresponding embodiment, in another embodiment of the present application, determining the target position of the preset rain effect in the virtual scene according to the current position of the virtual camera in the virtual scene and the preset operation mode of the virtual camera in S101 also includes:

[0050] If the preset operation mode is the follow operation mode, the target position is determined according to the current position of the virtual camera and the position of the controlled virtual object in the virtual scene.

[0051] The following operation mode is: the virtual camera always follows the movement of the controlled virtual object. For example, the controlled virtual object is a virtual person, and the virtual camera always follows the movement of the virtual person, so that the virtual person always appears in the lens of the virtual camera.

[0052] In the follow-up operation mode, the target position of the preset rain effect is determined according to the current position of the virtual camera and the position of the controlled virtual object. Thus, the virtual camera lens is always filled with rain effects, and the controlled virtual object is always in the rain effect in terms of visual effect, ensuring that the rain effect is presented more realistically in the virtual scene.

[0053] In summary, in this embodiment, if the preset operation mode is the follow operation mode, the target position is determined according to the current position of the virtual camera and the position of the controlled virtual object in the virtual scene, thereby ensuring that the rain effect is presented more realistically in the virtual scene.

[0054] On the basis of the above-mentioned embodiments, the embodiments of the present application further provide a method for determining a target position according to a current position of a virtual camera and a position of a controlled virtual object. Figure 2 A flowchart of a method for determining a target position according to the current position of a virtual camera and the position of a controlled virtual object provided by an embodiment of the present application. Figure 2 As shown, according to the current position of the virtual camera and the position of the controlled virtual object in the virtual scene, the target position is determined, including:

[0055] S201. Obtain the current positions of the virtual camera and the controlled virtual object.

[0056] S202: Calculate the current distance between the virtual camera and the controlled virtual object according to the current position of the virtual camera and the current position of the controlled virtual object.

[0057] S203: If the current distance is less than the second preset distance, determine the current position of the controlled virtual object as the target position.

[0058] If the current distance is less than the second preset distance, it means that the controlled virtual object is very close to the virtual camera. The current position of the controlled virtual object can be directly used as the target position, and the preset rain effect is centered on the controlled virtual object so that the preset rain effect moves with the controlled virtual object.

[0059] Therefore, in terms of visual effects, the lens of the virtual camera is always full of rain effects, and it is also ensured that the controlled virtual object is always in the rain effects, ensuring that the rain effects are presented more realistically in the virtual scene.

[0060] In summary, in this embodiment, the current positions of the virtual camera and the controlled virtual object are obtained; the current distance between the virtual camera and the controlled virtual object is calculated according to the current position of the virtual camera and the current position of the controlled virtual object; if the current distance is less than the second preset distance, the current position of the controlled virtual object is determined to be the target position. Thus, in terms of visual effects, the lens of the virtual camera is always full of rain effects, and the controlled virtual object is always in the rain effects, ensuring that the rain effects are more realistically presented in the virtual scene.

[0061] On the basis of the above embodiment, in another embodiment of the present application, the target position is determined according to the current position of the virtual camera and the position of the controlled virtual object in the virtual scene, further comprising:

[0062] If the current distance is greater than or equal to the second preset distance, the target position is determined according to the current position of the virtual camera and the third preset distance along the forward direction of the virtual camera.

[0063] If the current distance is greater than or equal to the second preset distance, it indicates that the controlled virtual object is far away from the virtual camera. If the current position of the controlled virtual object is used as the target position, it may not be possible to ensure that the lens of the virtual camera is always full of rain effects. Therefore, in this case, when the preset rain effect moves with the virtual camera, the position at the third preset distance from the lens of the virtual camera along the forward direction of the virtual camera is determined as the target position.

[0064] Therefore, in terms of visual effects, the lens of the virtual camera is always full of rain effects, and it is also ensured that the controlled virtual objects are also in the rain effects, ensuring that the rain effects are presented more realistically in the virtual scene.

[0065] In summary, in this embodiment, if the current distance is greater than or equal to the second preset distance, the target position is determined according to the current position of the virtual camera and the third preset distance along the forward direction of the virtual camera. Thus, in terms of visual effects, the lens of the virtual camera is always full of rain effects, and the controlled virtual object is also ensured to be in the rain effects, ensuring that the rain effects are presented more realistically in the virtual scene.

[0066] Based on the above embodiment, in another embodiment of the present application, if the current distance is less than the second preset distance, before determining that the current position of the controlled virtual object is the target position, the method further includes:

[0067] The second preset distance is determined according to the size of the area corresponding to the preset rain special effect and the size of rain particles in the preset rain special effect.

[0068] For example, the larger the area corresponding to the preset rain effect is, the larger the second preset distance is; otherwise, the smaller the second preset distance is. The larger the rain particles in the preset rain effect are, the larger the second preset distance is; otherwise, the smaller the second preset distance is. It should be noted that in actual determination of the second preset distance, it is necessary to comprehensively consider the size of the area corresponding to the preset rain effect and the size of the rain particles in the preset rain effect. Thus, it is ensured that all images in the lens of the virtual camera are covered by the rain effect.

[0069] In summary, in this embodiment, the second preset distance is determined according to the size of the area corresponding to the preset rain effect and the size of the rain particles in the preset rain effect, thereby ensuring that all images in the lens of the virtual camera are covered by the rain effect.

[0070] In the above Figure 1 On the basis of the corresponding embodiments, the embodiments of the present application also provide another method for processing rain special effects in a virtual scene. Figure 3 A flowchart of another method for processing rain special effects in a virtual scene provided by an embodiment of the present application. Figure 3 As shown, the method also includes:

[0071] S301: If there is a preset wind special effect in the virtual scene, determine the motion control parameters of rain particles in the preset rain special effect according to the current wind force information of the preset wind special effect.

[0072] In order to make the rain special effect more realistic, the motion control parameters of the rain particles in the preset rain special effect are determined according to the current wind force information of the preset wind special effect, so that the motion direction of the rain special effect is consistent with that of the wind special effect.

[0073] S302: Control the movement of rain particles in a preset rain special effect according to the motion control parameters.

[0074] In the existing rain special effects, if the lens of the virtual camera rotates, since the movement direction of the rain does not change, different movement directions of the rain particles will be seen from different angles.

[0075] By controlling the rain particles according to the motion control parameters, even when the lens of the virtual camera rotates, the movement direction of the rain special effect is consistent with the wind special effect, and the target position is consistent with the position of the virtual camera. Therefore, the rain particles combined with the wind special effect can always be seen, making the rain special effect more realistically presented in the virtual scene.

[0076] In summary, in this embodiment, if there is a preset wind special effect in the virtual scene, the motion control parameters of the rain particles in the preset rain special effect are determined according to the current wind force information of the preset wind special effect; and the rain particles in the preset rain special effect are controlled to move according to the motion control parameters. Thus, the rain special effect is presented more realistically in the virtual scene.

[0077] In the above Figure 3 On the basis of the corresponding embodiment, in another embodiment of the present application, the wind force information includes: wind direction information, and / or wind force magnitude.

[0078] In S301, according to the current wind force information of the preset wind special effect, the motion control parameters of the rain particles in the preset rain special effect are determined, including:

[0079] According to the wind direction information and / or the wind force, the motion control parameters of the rain particles are determined, and the motion control parameters include: rotation parameters and / or tilt parameters.

[0080] The information of wind effects is represented by wind direction information and / or wind force, and both wind direction information and wind force will affect rain particles.

[0081] For example, according to the influence relationship between the preset wind special effect and the preset rain special effect, the mapping relationship between "wind direction information and / or wind force" and "rotation parameter and / or tilt parameter" can be predetermined. During motion control, the rotation parameter and / or tilt parameter can be directly determined according to the above mapping relationship.

[0082] In summary, in this embodiment, the wind force information includes: wind direction information and / or wind force size; according to the wind direction information and / or wind force size, the motion control parameters of the rainwater particles are determined, and the motion control parameters include: rotation parameters and / or tilt parameters. Thus, the motion control parameters are accurately determined.

[0092] Furthermore, the determination module 401 is specifically configured to determine the target position along the forward direction of the virtual camera according to the current position of the virtual camera and the third preset distance if the current distance is greater than or equal to the second preset distance.

[0093] Furthermore, the determination module 401 is specifically configured to determine the second preset distance according to the size of the area corresponding to the preset rain special effect and the size of rain particles in the preset rain special effect.

Therefore, only a small range of preset rain effects need to be designed to achieve the effect of rain in all the images captured by the virtual camera, which reduces the number of rain particles, reduces the machine performance consumption, and reduces the cost of special effects.
