Technical Field

The invention relates to the field of games, in particular to a method and a device for calculating an occlusion rate, a storage medium and an electronic device.

Background

The 2.5D game uses a fixed lens view angle, and the model map uses a 3D rendering. In a game scene, a plurality of model maps, such as buildings, trees, stones and the like, can be placed. Therefore, in the scene of the 2.5D game, from the fixed view angle of the game, a part of the space is blocked by the scene model. When a player-controlled character walks to an area where the model obstructs the view, such as a game chief, the player is confused about the positioning of the position of the manipulated character, which can seriously affect the experience of the player.

In the scene test process, a game developer can check the model shielding problem of the scene. The positions of the model which are seriously shielded and can influence the position release of the combat replica, the position of a mission point, the position of npc and the like are recorded in various ways, and then the shielded model is subjected to position transfer or semi-transparent processing.

At present, test investigation is mainly realized by a human hand. And (3) manually operating the character running scene, recording the position coordinates and the screenshots of the scene model with serious shielding, sorting the position coordinates and the screenshots into a test feedback result, and then correspondingly modifying and adjusting by scene making personnel according to the feedback.

Fig. 2 is a schematic flowchart of a method for calculating an occlusion rate according to an embodiment of the present invention, and as shown in fig. 2, the method includes the following steps:

step S202, determining a current game interface where a first object is located, wherein the current game interface comprises a model chartlet;

step S204, determining the pixel value of a first pixel channel in the current game interface;

step S206, calculating the occlusion rate of the first object occluded by the model map in the current game interface based on the pixel value of the first pixel channel in the current game interface and the pixel values of the pixel channels of the first object.

Through the steps, the current game interface where the first object is located is determined, wherein the current game interface comprises the model chartlet; determining the pixel value of a first pixel channel in the current game interface; and then calculating the occlusion rate of the first object occluded by the model map in the current game interface based on the pixel value of the first pixel channel in the current game interface. The purpose of checking the shelters in the game scene is achieved, the technical effect of improving the checking efficiency of the shelters in the game scene is achieved, and the technical problems that in the related art, the speed control mode of equipment in the game is complex and the user experience is poor are solved.

It should be noted that the first object in this embodiment may be a character controlled in a game scene, such as the characters "mythology", "dragon 3", and the like shown in fig. 3. The current game interface may be a scene to which the first object moves.

It should be noted that the 3D coordinate system is a basic concept in 3D project development, and a cartesian coordinate system is adopted in general 3D games to describe coordinate information of an object. The Cartesian coordinate system is divided into a left-hand coordinate system and a right-hand coordinate system, wherein the left-hand coordinate system is that the Y axis points upwards, the X axis points rightwards, and the Z axis points forwards; the X, Y axes of the left and right hand coordinate systems are oriented in the same direction, while the Z axis is reversed, as shown in FIG. 4.

alpha channel: each pixel of an image has three channels of RGB, and later Alvy Ray Smith proposes that each pixel is added with an Alpha channel with a value of 0 to 1 for storing the transparency of the pixel in the picture, wherein 0 represents transparent and 1 represents opaque.

Remote Procedure Call Protocol (RPC): is a protocol that requests services from a remote computer program over a network without requiring knowledge of the underlying network technology. The RPC protocol assumes the existence of some transport protocol, such as TCP or UDP, for carrying information data between communication procedures.

Three-channel diagram: each pixel has 3 values to represent, so it is 3 channels. There is also a 4-channel diagram. For example, an RGB picture is a three-channel picture, an RGB color model is a color standard in the industry, and various colors are obtained by changing three color channels of red (R), green (G), and blue (B) and superimposing them, where RGB represents colors of three channels of red, green, and blue, and the standard includes almost all colors that can be perceived by human vision, and is one of the most widely used color systems at present. The digital image data may be represented by a matrix, each channel being a two-dimensional matrix.

The first pixel channel in this embodiment may be any one of three color channels of red (R), green (G), and blue (B).

In an optional embodiment, before determining the current game interface where the first object is located, a color replacement process needs to be performed on the model map, where the model map that needs to be replaced is all model maps in a scene that needs to be tested and a character model manipulated by a player in the game, specifically:

traversing model maps in a game scene where a current game interface is located, separating image channels of maps of scene models, and setting the pixel value of a first pixel channel of the model maps as a minimum value, wherein the pixel values of other pixel channels except the first pixel channel in the model maps are unchanged. If the first pixel channel is an R pixel channel, i.e. the value of all the R pixels in the game scene is set to 0, other properties of the model map, including transparency, are preserved.

Then, separating image channels of a character model chartlet (namely a first object) controlled in the game, and setting the pixel value of a first pixel channel in the first object as a maximum value; the pixel values of the other pixel channels in the first object except the first pixel channel are set to the minimum value. That is, all the pixels of the first object may be set to 255 for the R channel and 0 for the G and B channels. The picture processing only processes the R channel, and other attributes of the map, including transparency, are reserved. As shown in fig. 5, which is a game scene before no processing is performed, and fig. 6 is a game scene after image processing is performed, after all the pixel values of the G channel and the B channel of the first object manipulated in the game are set to 0, the first object becomes pure red. And after the value of the R channel pixel is set to 0 in the scene model map in the game scene, the color expression is more bluish-green.

In an alternative embodiment, the current game interface at which the first object is located is determined by: determining a coordinate point where a first object is located in a game scene; and intercepting the game interface within a preset range by taking the coordinate point as an origin to obtain the current game interface. In this embodiment, a method of traversing a scene by automatic way finding is required, a screenshot is performed on a game screen according to a coordinate point of a first object, and a relationship between a scene position of the first object and a corresponding screen display is established.

It should be noted that, in general, the game engine has a provision interface that can obtain the coordinate point where the first object is located, and also the current game screen capture. In the 3D coordinate system, the Y-axis coordinate represents the up-down position, so that only the X-axis and Z-axis coordinates need to be recorded regardless of the terrain height.

In order to avoid the problem that the position is too thin and the data amount is too large, the map coordinates in the game scene need to be compressed. It is assumed that the screenshot samples are taken every several units. The coordinate compression method is implemented by using a python script, wherein rate is a compression ratio, and if every five units are taken as a sampling point, the rate is equal to 5:

def compress_position(x,z,rate):

x＝round(x/rate)

z＝round(z/rate)

return x,z

then, screenshot needs to be carried out on the game picture of the coordinate point where the first object is located, and for convenience of management, the screenshot picture is named by ' scene name _ X axis data _ Z axis data ' png '. And if the screenshot picture naming file corresponding to the sampling point does not exist, screenshot, and if the screenshot picture naming file exists, screenshot does not need to be repeated.

In an optional embodiment, after the current game interface where the first object is located is obtained, a total pixel value of a first pixel channel included in the first object needs to be determined; calculating the ratio of the pixel value of a first pixel channel in the current game interface to the total pixel value; an occlusion rate is determined based on the ratio.

It should be noted that the occlusion rate is defined herein to express the degree of occlusion of the first object by the scene model map in the game scene. There are two extremes: in the first case, when the first object is completely occluded in the scene by the model map, i.e. the model map of the first object is not displayed at all, the occlusion rate is 100%, i.e. 1. In the second case, when the hero is completely unobstructed in the scene, the obstruction rate is 0%, i.e., 0%. The other is between the two.

Another concept is translucency. When the first object is shielded by the model of the scene, if the shielded model map is subjected to semi-transparent processing, the higher the transparency is, the more obvious the first object is displayed, and when the first object is completely transparent, the first object is not shielded at all; conversely, the lower the transparency, the less clear the chief angle display, and when completely opaque, the first object is completely obscured.

The above phenomenon can be resolved using the translucent blending algorithm AlphaBlend. Assuming that one image is A and the other semi-transparent image is B, looking through B to see A, the apparent image C is a mixture of B and A, and the transparency of B is alpha (values 0-1, 1 is completely transparent, 0 is completely opaque).

The Alpha mixing formula is as follows:

R(C)＝(1-alpha)*R(B)+alpha*R(A)；

G(C)＝(1-alpha)*G(B)+alpha*G(A)；

B(C)＝(1-alpha)*B(B)+alpha*B(A)；

wherein, R (x), G (x), B (x) respectively refer to RGB component primary color values of color x.

When the B image is completely transparent (alpha ═ 1), r (c) ═ r (a), g (c) ═ g (a), B (c) ═ B (a); the a picture is not occluded at all by the B picture. When B is completely opaque (alpha ═ 0), r (c) ═ r (B), g (c) ═ g (B), B (c) ═ B (B); the a picture is completely occluded by the B picture.

Based on the above algorithm, the calculation of the occlusion rate specifically includes:

since the R channel values of all the model maps in the game scene are set to 0, the R channel value of the principal angle model map of the first object is set to 255. Therefore, the more the first object is occluded, the less the sum of the values of the R channel matrix in the picture of the screenshot. When the first object is completely shielded, the R channel values of all the pixel points in the screenshot are all 0. When the first object is not occluded at all, the red part is the most, and the sum of the values of the R channel matrix of the screenshot is the largest.

Where R _ Sum represents the Sum of all elements in the matrix of the R channel in a certain screenshot (current game interface) (e.g., scene A _5_10. png). R _ Sum _ Max represents the Sum of all elements in the matrix of the R channel in the screenshot when the first object is not occluded at all.

In a certain screenshot, the calculation formula of the main corner shielding rate is as follows:

the shielding rate is 1-R _ Sum/R _ Sum _ Max

When the chief angle is not occluded at all, R _ Sum is equal to R _ Sum _ Max, so the occlusion rate is equal to 0. When the main corner is completely shielded and not displayed, the values of R channels of all pixels in the screenshot are 0, R _ Sum is equal to 0, and therefore the shielding rate is equal to 1.

In a certain screenshot, the calculation formula of the main corner shielding rate can be as follows:

the shielding rate is R _ Sum/R _ Sum _ Max

When the chief angle is not occluded at all, R _ Sum is equal to R _ Sum _ Max, so the occlusion rate is equal to 1. When the main corner is completely shielded and not displayed, the values of R channels of all pixels in the screenshot are 0, R _ Sum is equal to 0, and therefore the shielding rate is equal to 0.

In an alternative embodiment, after calculating the occlusion rate of the first object occluded by the model map in the current game interface based on the pixel value of the first pixel channel in the current game interface, the occlusion rate of the first object at each coordinate point in the game scene needs to be determined; setting different color marks at each coordinate point where the first object is located based on the shielding rate at each coordinate point; and drawing an occlusion rate thermodynamic diagram of the first object in the game scene by using different color identifiers.

It should be noted that a scene occlusion thermodynamic diagram needs to be drawn according to the occlusion rate corresponding to the coordinate point, and different colors need to be drawn at the corresponding coordinate according to the size of the occlusion rate. Fig. 7 is a game scene occlusion thermodynamic diagram in the present embodiment, and as shown in fig. 7, dark colors represent a higher occlusion ratio, and light colors represent a lower occlusion ratio. Fig. 8 is a schematic diagram of colors corresponding to the occlusion rate in this embodiment.

In an optional embodiment, after drawing the occlusion rate thermodynamic diagram of the first object in the game scene by using different color identifiers, respective anchor points of the first object may also be set at the different color identifiers, where the respective anchor points include: each occlusion rate corresponding to each color identifier, and a coordinate value of the first object at each color identifier; and displaying the occlusion condition of the first object in the game scene by using each positioning point.

It should be noted that each set anchor point is to add click listening to the thermodynamic diagram. For example, a left click thermodynamic diagram location may display an occlusion ratio value for that location (as shown in FIG. 9). The right click thermodynamic location selection transfers the first object to the coordinate point (as shown in FIG. 10). When a coordinate point on the user right-click thermodynamic diagram pops up a button for positioning to a client scene position, the user clicks the button, an rpc instruction is sent to the game, and a first object in the game is transmitted to a coordinate position corresponding to the thermodynamic diagram, so that a game developer can check the actual shielding condition.

In summary, all the way-finding points are automatically traversed by controlling the game role, the coordinate point of each way-finding position is recorded, and the shielding rate of the scene model on the coordinate point is calculated. Drawing a thermodynamic diagram for each coordinate point and the corresponding shielding rate; and distinguishing numerical intervals of the shielding rate by using different colors. And click monitoring is set for the thermodynamic diagrams, the click thermodynamic diagrams can display game screenshots of the click coordinates, and in addition, the position of the thermodynamic diagrams can be clicked right to select and transmit the principal angle to the coordinate point, so that game developers can check the actual shielding condition. An automatic means is created, and the shielding and checking efficiency of the scene model of the 2.5D game is improved. The following technical problems in the related art can be solved: a method for calculating the rate of the occlusion of a game character by a scene model (hereinafter, referred to as the occlusion rate) is designed. And calculating the shielding rate of the character in the game at all the road-searching coordinate points of the scene. And visually displaying the condition that the game role at each position of the scene is blocked. The method realizes efficient completion of the shielding test of the scene model of the game, and game developers can quickly know the shielding condition of the whole scene, thereby bringing great convenience to the scene test.

It should be noted that the main body for executing the above steps may be the terminal shown in fig. 1, but is not limited thereto.

An embodiment of the present invention further provides a device for calculating an occlusion rate, and fig. 11 is a schematic structural diagram of the device for calculating an occlusion rate according to the embodiment of the present invention, as shown in fig. 11, the device includes:

a first determining module 1102, configured to determine a current game interface where the first object is located, where the current game interface includes a model map;

a second determining module 1104, configured to determine a pixel value of the first pixel channel in the current game interface;

a calculating module 1106, configured to calculate an occlusion rate of the first object being occluded by the model map in the current game interface, based on the pixel value of the first pixel channel in the current game interface and the pixel values of the pixel channels of the first object.

It should be noted that the first object in the present embodiment may be a character controlled in a game scene, such as the characters "nvwa", "dragon 3", and the like shown in fig. 3. The current game interface may be a scene to which the first object moves.

It should be noted that the 3D coordinate system is a basic concept in 3D project development, and a cartesian coordinate system is adopted in general 3D games to describe coordinate information of an object. The Cartesian coordinate system is divided into a left-hand coordinate system and a right-hand coordinate system, wherein the left-hand coordinate system is that the Y axis points upwards, the X axis points rightwards, and the Z axis points forwards; the X, Y axes of the left and right hand coordinate systems are oriented in the same direction, while the Z axis is reversed.

Then, separating image channels of the character model chartlet (namely a first object) controlled in the game, and setting the pixel value of the first pixel channel in the first object as the maximum value; the pixel values of the other pixel channels in the first object except the first pixel channel are set to the minimum value. That is, all the pixels of the first object may be set to 255 for the R channel and 0 for the G and B channels. The picture processing only processes the R channel, and other attributes of the map, including transparency, are reserved. As shown in fig. 5, which is a game scene before no processing is performed, and fig. 6 is a game scene after image processing is performed, after all the pixel values of the G channel and the B channel of the first object manipulated in the game are set to 0, the first object becomes pure red. And after the value of the R channel pixel is set to 0 in the scene model map in the game scene, the color expression is more bluish-green.

In order to avoid the problem that the position is too fine and the data size is too large, the map coordinates in the game scene need to be compressed. It is assumed that the screenshot samples are taken every several units. The coordinate compression method is implemented by using a python script, wherein rate is a compression ratio, and if every five units are taken as a sampling point, the rate is equal to 5:

def compress_position(x,z,rate):

x＝round(x/rate)

z＝round(z/rate)

return x,z

It should be noted that the occlusion rate is defined herein to express the degree of occlusion of the first object by the scene model map in the game scene. There are two extremes: in the first case, when the first object is completely occluded by the model map in the scene, i.e. the model map of the first object is not displayed at all, the occlusion rate is

100%, i.e. 1. In the second case, when the hero is completely unobstructed in the scene, the obstruction rate is 0%, i.e., 0%. The other is between the two.

Another concept is translucency. When the first object is occluded by the model of the scene, the higher the transparency, the more apparent the first object will appear if the occluded model map is translucently processed, and when it is completely transparent,

the first object will be completely unobstructed; conversely, the lower the transparency, the less clear the chief angle display, and when completely opaque, the first object is completely obscured.

The Alpha mixing formula is as follows:

R(C)＝(1-alpha)*R(B)+alpha*R(A)；

G(C)＝(1-alpha)*G(B)+alpha*G(A)；

B(C)＝(1-alpha)*B(B)+alpha*B(A)；

since the R channel values of all the model maps in the game scene are set to 0, the R channel value of the principal angle model map of the first object is set to 255. Therefore, the more the first object is occluded, the less the sum of the values of the R channel matrix in the picture of the screenshot. When the first object is completely shielded, the R channel values of all the pixel points in the screenshot are all 0. When the first object is not occluded at all, the red portion is the most, and the sum of the values of the R channel matrix of the screenshot is the largest.

occlusion ratio 1-R _ Sum/R _ Sum _ Max

the shielding rate is R _ Sum/R _ Sum _ Max

When the chief angle is not occluded at all, R _ Sum is equal to R _ Sum _ Max, so the occlusion rate is equal to 1. When the main corner is completely shielded and not displayed, the values on the R channels of all pixels in the screenshot are 0, R _ Sum is equal to 0, and therefore the shielding rate is equal to 0.

In an alternative embodiment, after calculating the occlusion rate of the first object occluded by the model map in the current game interface based on the pixel value of the first pixel channel in the current game interface, the occlusion rate of the first object at each coordinate point in the game scene needs to be determined; setting different color marks at each coordinate point where the first object is located based on the shielding rate at each coordinate point; and drawing an occlusion rate thermodynamic diagram of the first object in the game scene by using different color identifications.

It should be noted that a scene occlusion thermodynamic diagram needs to be drawn according to the occlusion rate corresponding to the coordinate point, and different colors need to be drawn at the corresponding coordinate according to the size of the occlusion rate. Fig. 7 is a game scene occlusion thermodynamic diagram in the present embodiment, and as shown in fig. 7, dark colors represent a higher occlusion ratio, and light colors represent a lower occlusion ratio. Fig. 8 shows colors corresponding to the shading rate in this embodiment.

In an optional embodiment, after the occlusion rate thermodynamic diagram of the first object in the game scene is drawn by using different color identifiers, respective anchor points of the first object may be further set at the different color identifiers, where the respective anchor points include: each occlusion rate corresponding to each color identifier, and a coordinate value of the first object at each color identifier; and displaying the occlusion condition of the first object in the game scene by using each positioning point.

In summary, all the way-finding points are automatically traversed by controlling the game role, the coordinate point of each way-finding position is recorded, and the shielding rate of the scene model on the coordinate point is calculated. Drawing a thermodynamic diagram for each coordinate point and the corresponding shielding rate of the coordinate point; and distinguishing numerical intervals of the shielding rate by using different colors. And click monitoring is set for the thermodynamic diagram, the click thermodynamic diagram can display a game screenshot of the click coordinate, and in addition, the position of the thermodynamic diagram can be clicked right to select and transmit the principal angle to the coordinate point, so that game developers can check the actual shielding condition. An automatic means is created, and the shielding and checking efficiency of the scene model of the 2.5D game is improved. The following technical problems in the related art can be solved: a method for calculating the rate of the occlusion of a game character by a scene model (hereinafter, referred to as the occlusion rate) is designed. And calculating the shielding rate of the character in the game at all the road-searching coordinate points of the scene. And visually displaying the shielded condition of the game role at each position of the scene. The method realizes efficient completion of the shielding test of the scene model of the game, and game developers can quickly know the shielding condition of the whole scene, thereby bringing great convenience to the scene test.
