Description

Background Art

[0002] In SLG large-scene games, players see more areas than in traditional games, including snow, desert, rivers, etc. The technical solution for wetting the ground when it rains needs to wet the ground according to the area where it rains.

[0003] In the related art, a smooth wet effect can be obtained by making a material specifically for wetness, setting the roughness of the material to 0, and changing the base color of the material to black. However, if the entire material is set, the entire material will be wet. In order to solve this problem, a mask can be made by vertex color drawing. After the mask is made, only the vertices that have been drawn will have a wet effect, and the vertices that have not been drawn will not have a wet effect.

[0059] In this example implementation, a special effect generation method is first provided. Figure 1 As shown, the special effect generation method may include the following steps:

[0060] Step S110. Obtain a game map, generate a target map according to the game map and the target rainfall area, and determine a target area for generating special effects in the game scene based on the target map;

[0061] Step S120: Acquire a target noise map, determine a first region in the target region based on the target noise map, adjust the roughness and normal of the first region, and generate a first special effect in the first region;

[0062] Step S130: superimpose a special effect map on the first area to obtain a target special effect.

[0063] The above-mentioned special effect generation method obtains a game map, generates a target map based on the game map and the target rainfall area, and determines the target area for generating special effects in the game scene based on the target map; obtains a target noise map, determines a first area in the target area based on the target noise map, adjusts the roughness and normal of the first area, and generates a first special effect in the first area; and superimposes a special effect map on the first area to obtain the target special effect. On the one hand, after obtaining the game map, a target map is generated based on the game map and the target rainfall area, and during the game operation, the target area for rain in the game scene is determined based on the target map, thereby realizing automatic identification of the area for realizing the target special effect and improving the efficiency of realizing the target special effect. On the other hand, after determining the target area, a target noise map is obtained, and the target noise map is used to determine the first area in the target area for generating the target special effect. After determining the first area, the roughness and normal of the first area are adjusted to generate the first special effect in the first area. After obtaining the first special effect, a special effect map is superimposed in the first area to generate the target special effect. This solves the problem in related technologies that art needs to be used to draw the roughness of the material to achieve the target special effect, realizes real-time calculation and realization of the target special effect, and improves the efficiency of artists in producing assets.

[0064] Hereinafter, each step involved in the special effect generation method according to the exemplary embodiment of the present disclosure is explained and illustrated in detail.

[0065] In step S110, a game map is obtained, a target map is generated according to the game map and the target rainfall area, and a target area for generating special effects in the game scene is determined based on the target map.

[0066] In this example embodiment, the game map obtained is a map in the big world game, which includes the planned districts, counties and other areas in the game, and may also include various terrains. In this example embodiment, the game map is not specifically limited. The target rainfall area can be determined according to the range of dark clouds in the game scene. After the game map is obtained, the target map can be generated according to the game map and the target rainfall area. Figure 2 As shown, a game map is obtained, a target map is generated according to the game map and the target rainfall area, and a target area for generating special effects in the game scene is determined based on the target map, including:

[0067] Step S210. Obtain the game map and generate a map texture corresponding to the game map;

[0068] Step S220. Setting the color of the target rainfall area in the map texture to a first color to obtain the target texture;

[0069] Step S230: Determine the area in the target map whose color is the first color as the target area.

[0070] Below, step S210-step S230 will be further explained and illustrated. Specifically, a map of the game world is obtained, and a corresponding map texture is generated according to the obtained game map, wherein the default color in the generated map texture is black. After the map texture is generated, the color of the target rainfall area in the map texture is set to the first color, wherein the first color can be white, and the first color is different from the default color of the map texture. In this example embodiment, the first color is not specifically limited. After the color of the target rainfall area is set to the first color, a target texture is generated. During the game operation, when the color of a certain area in the target texture is read as the first color, the area with the first color is determined as the target area. The target area is the area in the game where it is required to rain.

[0071] In this example embodiment, after obtaining the target map, the special effect generation method further includes:

[0072] The target map is interpolated based on the colors in the target map.

[0073] Specifically, the colors of each area in the target map can be obtained, and the target map can be interpolated using the colors of each area to achieve a fade-in and fade-out effect of the target map, so that when the surface in the game scene is wet, not all scenes are wet at the same time, thereby improving the authenticity of the surface wetting effect.

[0074] Furthermore, after determining the target area, a preset map may be superimposed in the target area to generate a special effect of water on the ground surface due to rainfall in the target area, wherein the preset map may be a water surface map, and the preset map is not specifically limited in this example embodiment.

[0075] In this example embodiment, the target map can be generated to control the raining area, which can include the wetted surface area and the shadow area of ​​dark clouds, which is not specifically limited in this example embodiment. The target map is generated to improve the efficiency of generating the wetted surface effect.

[0076] In step S120, a target noise map is acquired, a first region in the target region is determined based on the target noise map, roughness and normal of the first region are adjusted, and a first special effect is generated in the first region.

[0077] In this example embodiment, after the target area where the target special effect needs to be achieved is confirmed according to the target map during game operation, a preset target noise map can be obtained, wherein the noise map is randomly generated, and the target noise map is used to determine the first area where the first special effect needs to be generated in the target area. In addition, if the roughness is directly set for the entire surface, the entire surface will be wetted, and the difference between the wetted surface caused by rain in the real scene is large. Therefore, the range of the roughness in the target area can be further controlled by the range of the target noise map to achieve a more realistic wetted surface effect.

[0078] refer to Figure 3 As shown, the acquiring of the target noise map, determining a first region in the target region based on the target noise map, adjusting the roughness and the normal of the first region, and generating a first special effect in the first region include:

[0079] Step S310: randomly generate the target noise map, obtain a first part of the target noise map, and determine a first area corresponding to the first part in the target area;

[0080] Step S320. Set the roughness of the first area to a preset roughness, and set the normal of the first area to a target vector, and form a first special effect of surface water accumulation in the first area based on the target vector.

[0081] In the following, step S310 and step S320 will be further explained and illustrated. Specifically, a target noise map is generated, which is a randomly generated black and white image. The size of the target noise map matches the target area, and the target noise map can be tiled into the target area. In this example embodiment, the method for generating the noise map is not specifically limited. The generated noise map can refer to Figure 4 As shown. After the preset map is superimposed on the target area, in order to generate the special effect of water accumulation on the surface, it is necessary to adjust the roughness and normal of some areas in the target area. The first area in the target area can be determined by the first part of the target noise map, that is, the part of the target noise map with white color can be determined as the first part. After obtaining the first part of the target noise map, the first area corresponding to the first part of the target noise map is determined in the target area, and the roughness of the first area in the target area is set to the preset roughness. The preset roughness can be 0, and there is no specific limitation on this in the present example embodiment. After the roughness of the first area is set to the preset roughness, when there is water accumulation on the ground, there is no uneven change in the water accumulation area. Therefore, the vector of the first area can also be set to the target vector. After the vector of the first area is set to the first vector, the first special effect of surface water accumulation is formed in the first area.

[0082] For further reference, Figure 5 As shown, after the roughness of the first area is set to a preset roughness, the method further includes:

[0083] Step S510. Acquire a second area in the target area and the surface roughness of the second area; wherein the second area is an area in the target area excluding the first area;

[0084] Step S520: Perform interpolation processing on the roughness of the first area and the second area in the target area.

[0085] In the following, step S510 and step S520 are further explained and illustrated. Specifically, a second area in the target area is obtained, and the second area is an area in the target area other than the first area. After the second area is obtained, the surface roughness of the second area can also be obtained, and the roughness of the first area and the second area are interpolated to achieve the transition of the roughness between the first area and the second area, so as to ensure the smoothness of the roughness between different areas in the target area.

[0086] In this example embodiment, reference Figure 6 As shown, the step of setting the normal of the first area as a target vector and forming a first special effect of surface water accumulation in the first area based on the target vector includes:

[0087] Step S610. Obtain the surface normal vector of the first region, and update the surface normal vector of the first region to the target vector;

[0088] Step S620: Based on the target vector, a first special effect of surface water accumulation is formed in the first area.

[0089] Below, step S610 and step S620 will be further explained and illustrated. Specifically, after the roughness adjustment of the first area is completed, since there is no uneven change on the surface when there is water accumulation on the surface, the normal of the first area can be set to indicate that the first area is a water accumulation area. Get the surface normal vector of the first area, and update the surface normal vector to the target vector, where the target vector can be (0,0,1). After setting the surface normal of the first area of ​​the target area to the target vector, the first area will not show uneven changes, that is, a water accumulation special effect is generated in the first area.

[0090] In this example embodiment, the surface normal of the second area in the target area may be the normal of the terrain material, and the second area is the area other than the first area in the target area. After the surface normal of the first area in the target area is set as the target vector, the normals in the first area and the second area in the target area may be transitioned. Figure 7 As shown, the method also includes:

[0091] Step S710. Obtaining the surface normal of the second area in the target area;

[0092] Step S720: Perform transition processing on the surface normals of the first area and the second area by interpolation.

[0093] In the following, step S710 and step S720 are further explained and illustrated. Specifically, the surface normal of the second area in the target area is obtained, wherein the surface normal of the second area is the normal of the terrain material in the second area. After obtaining the surface normal of the second area, the surface normal vectors of the first area and the second area can be interpolated to achieve a smooth transition of the surface normal from the first area to the second area.

[0094] Furthermore, after the water accumulation special effect is realized in the first area of ​​the target area through the target vector, a special effect map can be superimposed in the first area to realize the target special effect. Figure 8 As shown, a special effect map is superimposed on the first area to obtain a target special effect, including:

[0095] Step S810. Obtain a water wave map and a current game time, input the water wave map and the current game time into an objective function, and obtain a water wave diffusion map corresponding to the water wave map;

[0096] Step S820: acquiring a normal line of the water wave diffusion map, and generating a three-dimensional normal line of the water wave diffusion map based on the normal line;

[0097] Step S830: superimposing the three-dimensional normal line on the water wave diffusion map to obtain a three-dimensional water wave diffusion map corresponding to the water wave map;

[0098] Step S840: superimpose the three-dimensional water wave diffusion image on the first area to obtain the target special effects of the target area.

[0099] Below, step S810-step S840 will be further explained and illustrated. Specifically, a preset water wave map is obtained, wherein the preset water wave map can be a circular map, and the circular map contains normals and diffusion transition information. During the game running process, it is also necessary to obtain the current game time in the game, and input the water wave map and the current game time into the objective function, wherein the objective function can be a trigonometric function, and the trigonometric function can be a sine function or a cosine function. In this example embodiment, the objective function is not specifically limited. The absolute value of the value obtained by the objective function is taken, and the water wave diffusion map corresponding to the water wave map is obtained through the objective function. After obtaining the water wave diffusion map, since the water wave map contains normal information, the normal information of the water wave diffusion map can be obtained. The normal information is two-dimensional normal information. After obtaining the normal information of the water wave diffusion map, a three-dimensional normal can be obtained according to the normal information of the water wave diffusion map. After obtaining the three-dimensional normal, the three-dimensional normal information is superimposed on the water wave diffusion map to obtain a three-dimensional water wave diffusion map corresponding to the water wave map. After obtaining the three-dimensional water wave diffusion map, the three-dimensional water wave diffusion map can be superimposed on the first special effect of surface water accumulation formed in the first area, so as to wet the surface of the target area, form surface water in the first area of ​​the target area, and have the effect of water ripple diffusion.

[0100] In an exemplary embodiment of the present disclosure, the wetted area can also be recorded by vertex color and the area can be wetted. When drawing the color of the vertex, the color of the vertex can be drawn directly in the UE engine. The brush and the color of the brush can be selected in the engine, and the color of the vertex can be interpolated. The color of the vertex obtained can be regarded as the noise map recorded in the above embodiment.

[0101] The special effects generation method provided by the example embodiment of the present disclosure has at least the following advantages: on the one hand, after obtaining the game map, a target map is generated according to the game map and the target rainfall area, and the target area for rain in the game scene is determined according to the target map during the game operation, thereby realizing automatic identification of the area for realizing the target special effects and improving the efficiency of realizing the target special effects. On the other hand, after determining the target area, a target noise map is obtained, and the first area for generating the target special effects in the target area is determined by using the target noise map. After determining the first area, the roughness and normal of the first area are adjusted, and the first special effect is generated in the first area. After obtaining the first special effect, the special effect map is superimposed in the first area to generate the target special effect, which solves the problem in the related art that the roughness of the material needs to be drawn by art to realize the target special effect, realizes real-time calculation and realization of the target special effect, and improves the efficiency of artists in producing assets.
