Description

TECHNICAL FIELD

[0001] The present application relates to a game scene pathfinding mask editing and generating method, in particular to a scene pathfinding mask editing and generating method and system. BACKGROUND

[0002] In the development of a game, it is often necessary to pathfinding bake a scene to determine which parts can be walked. For a game scene, a mask is usually made as an unpathfinding part and then baked to determine the pathfinding part in the scene. However, making a mask as an obstacle requires a large amount of man-hours and a cumbersome production process.

[0003] In a two-dimensional game scene, the prior art pathfinding grid baking is performed by creating a large number of three-dimensional object obstacles in the scene to place in the unpathfinding place as a mask, or drawing a three-dimensional patch in a three-dimensional modeling software to cover the unpathfinding place, thereby baking the pathfinding grid as a mask. Such a mask generation method requires a large amount of man-hours for an artist to create a large number of three-dimensional objects, then place the three-dimensional objects in the scene and drag the obstacles to the appropriate position, or create a three-dimensional patch to draw a large number of vertices in the patch to determine that the patch covers the unpathfinding place in the scene.

[0004] In a three-dimensional game scene, the prior art mainly bakes the scene pathfinding grid according to editing baking parameters such as a slope greater than a certain value, a walking character radius, etc. The main problem of this method is that the details are uncontrollable, such as whether a certain part of the scene is pathfinding or not cannot be determined intuitively by setting the parameters, and some places are contradictory, such as a place with a larger slope is expected to be pathfinding, and another place with a smaller slope is not expected to be pathfinding. Such a method cannot cover all pathfinding grid requirements with uniform parameters. A three-dimensional game scene can also determine the pathfinding area by creating a three-dimensional object as an obstacle. The disadvantage of this method is the same as that in the two-dimensional game scene. SUMMARY

[0005] To overcome the above problems, the purpose of the present application is to provide a game scene pathfinding mask editing and generating method and system which is convenient to use and saves a large amount of man-hours, realizes fast editing, ensures controllable pathfinding of each area in the whole scene, and improves the scene pathfinding baking efficiency and baking accuracy.

[0006] The present application adopts the following scheme to realize the above purposes:

[0008] Step S1: according to the size of the game scene in the engine, according to the required accuracy requirements, generate a translucent texture map of the size of the scene multiplied by the accuracy multiple n;

[0009] Step S2: display the game scene using the top view angle in the preview box of the pathfinding mask editing tool, and cover the generated translucent texture map on the game scene with the same size;

[0010] Step S3: set the brush size according to the size of the translucent texture map, and draw the pathfinding mask on the translucent texture map;

[0012] Step S5: set all the pathfinding mask units as non-pathfinding obstacles, and bake the pathfinding grid of the game scene.

[0013] Further, in step S2, the method of displaying the game scene using the top view angle in the preview box of the pathfinding mask editing tool is: loading the game scene resource, and creating an orthogonal camera, the display area of the camera being the area of the game scene resource in the engine, and displaying the effect in the preview box of the tool.

[0014] Further, in step S2, the method of covering the generated translucent texture map on the game scene with the same size is: compressing the size of the translucent texture map to the size of the game scene, and displaying the generated translucent texture map on the top view camera effect of the scene, the size of the translucent texture map in the preview box of the tool being corresponding to the size of the game scene.

[0015] Further, step S3 is further specific: after selecting the brush type and size, drawing the mask on the translucent texture map, and the transparency of the pixels corresponding to the translucent texture map in the place brushed by the brush changes to 0 with the specified radius size.

[0016] Further, step S4 is further specific: generating the pathfinding mask unit of the game scene in the engine according to the pixels of the translucent texture map after drawing the pathfinding mask, according to the accuracy multiple n, the size of the translucent texture map of the pathfinding mask is n times the size of the game scene in the engine, the size of each pixel of the translucent texture map of the pathfinding mask in the engine is: (1 / n)*(1 / n); in the game scene, no pathfinding mask unit is generated in the place where the pixel of the translucent texture map is 0, and a pathfinding mask unit is generated in the corresponding position where the pixel of the translucent texture map is not 0.

[0018] The map generating module is used to generate a translucent texture map with a size of the scene size multiplied by the precision multiple n according to the size of the game scene in the engine and the required precision requirement.

[0019] The covering module is used to display the scene using a top view in the preview frame of the pathfinding mask editing tool, and cover the generated translucent texture map on the game scene with the same size.

[0020] The drawing code module is used to set the brush size according to the size of the translucent texture map, and draw the pathfinding mask on the translucent texture map.

[0021] The pathfinding mask generating module is used to generate the corresponding pathfinding mask unit in the game scene according to the translucent texture map after the pathfinding mask is drawn.

[0022] The baking module is used to set all pathfinding mask units as non-pathfinding obstacles, and bake the pathfinding grid of the game scene.

[0023] Further, in the covering module, the method for displaying the game scene using a top view in the preview frame of the pathfinding mask editing tool is: loading the game scene resource, and creating an orthogonal camera, the display area of the camera being the area of the game scene resource in the engine, and displaying the effect in the preview frame of the tool.

[0024] Further, in the covering module, the method for covering the generated translucent texture map on the game scene with the same size is: compressing the size of the translucent texture map to the size of the game scene, and displaying the generated translucent texture map on the top view camera effect of the scene, the size of the translucent texture map in the preview frame of the tool being corresponding to the size of the game scene.

[0025] Further, the drawing code module is further specifically: after selecting the brush type and size, drawing the pathfinding mask on the translucent texture map, and changing the transparency of the corresponding pixels of the translucent texture map to 0 within the specified radius size where the brush passes.

[0026] Furthermore, the pathfinding mask generation module is further specified as follows: Based on the pixels of the semi-transparent texture map after the pathfinding mask is drawn, a pathfinding mask unit for the game scene in the engine is generated. According to the precision multiple n, the size of the semi-transparent texture map for drawing the pathfinding mask is n times the size of the game scene in the engine. The size of each pixel of the semi-transparent texture map in the engine corresponding to the scene size is (1 / n)*(1 / n). In the game scene, no pathfinding mask unit is generated where the semi-transparent texture map pixel is 0, and a pathfinding mask unit is generated at the corresponding position where the semi-transparent texture map pixel is not 0.

[0027] The beneficial effects of this invention are as follows: This invention uses a brush to paint the pixels of a semi-transparent texture map and automatically generates obstacles, which simplifies the tedious operation of creating a large number of 3D objects and dragging a large number of face vertices; by matching the scene view with the semi-transparent texture map to be painted, it solves the problem of the large amount of work of dragging a large number of 3D objects and a large number of face vertices to a specified position, thus improving the efficiency of scene pathfinding baking.
