Wherein the processor 120 may perform the steps of the method shown in fig. 2.
As shown in fig. 2, fig. 2 shows a flowchart of a method for setting a sound source in a virtual environment according to an embodiment of the present application, including steps S210 to S230.
Step S210: and acquiring the boundary of the target environment and the position of the role.
In an embodiment of the present application, the target environment may be various environments in the virtual scene of interest, such as a snow mountain, a lake, an ocean, a street, a recreation ground, and the like, which is not limited in the present application. The method for determining the target environment can be various, and can be judged according to whether the distance between the character and the center of the environment area is larger than a preset threshold value, wherein the environment area does not belong to the target environment under the condition that the distance between the character and the center of the environment area is larger than the preset threshold value, and the environment area belongs to the target environment under the condition that the distance between the character and the center of the environment area is smaller than or equal to the preset threshold value; as the scene in the game interface is continuously changed along with the movement of the character when the character moves, the environment area displayed in the game interface can be used as the target environment at the same moment or in the same frame of picture when the character position is acquired, or the target environment can be determined by other methods, and the application is not limited in this way.
The boundary is a kind of marking boundary for dividing the environment area, and may be an outer contour line of the environment area of various shapes. The target environment boundary may be an outer boundary of the virtual environment model of interest in connection with the character position. The character position may be where, and the azimuth the character is located.
For example, assuming that three environmental areas of a forest, a waterfall and a street are set in the game, and the distances between the characters and the three environmental areas are equal to and smaller than a preset threshold value, the forest, waterfall and street all belong to target environments, and the boundaries of the forest, waterfall and street all belong to target environment boundaries; under the condition that the role is located between the forest environment area and the waterfall environment area and the distance between the role and the street environment area is larger than the set threshold value, the street environment does not belong to the target environment, the boundary of the street environment area does not belong to the target environment boundary, under the condition that the role is located at the middle point between the forest environment area and the waterfall environment area, the forest environment and the waterfall environment both belong to the target environment, and the boundary of the forest environment area and the boundary of the waterfall environment area are both the target environment boundary.
In practical application, the target environment boundary and the role position can be acquired regularly according to a preset time interval.
The preset time interval may be determined according to actual requirements, for example, n times of acquisition of the target environment boundary and the role position (n is an integer greater than or equal to 1) per second may be set, or one time of acquisition of the target environment boundary and the role position (x is an integer greater than or equal to 1) per x frames, which is not limited in this application.
Step S220: based on the target environment boundary and the character position, it is determined whether the character is in the target environment, if so, step S221 is executed, and if not, step S222 is executed.
Step S221: and setting the same position data as the roles for the virtual sound source. After setting the same position data as the character for the virtual sound source, step S230 is continued to be performed.
Step S222: and calculating the distance between the character and the boundary of the target environment, and setting position data for the virtual sound source based on the calculated distance. After setting the position data for the virtual sound source, step S230 is continued.
The method for judging whether the character is in the target environment may be various, for example, a coordinate system may be established based on the target environment, a center point in the target environment is used as a coordinate origin, a target environment boundary and a character position are represented in a coordinate form, a distance between the target environment boundary and the character position is calculated, if the distance between the target environment boundary and the character position is greater than a preset value, the character is judged to be located outside the target environment, if the distance between the target environment boundary and the character position is less than the preset value, the character is judged to be located in the target environment, and if the distance between the target environment boundary and the character position is equal to the preset value, the character is judged to be located on the target environment boundary. In addition, whether the role is in the target environment can be judged by other methods, and the application is not limited to the method.
Setting position data identical to the position data of the character for the virtual sound source if the character is in the target environment, and moving the virtual sound source along with the movement of the character if the character is moved in the target environment; if the character moves from the target environment to the outside of the target environment, the virtual sound source still moves along with the movement of the character when the character is still in the target environment, the distance between the character and the target environment is calculated after the character moves to the outside of the target environment, and position data is set for the virtual sound source based on the distance between the character and the target environment.
There are various methods for calculating the distance between the character and the boundary of the target environment, for example, any one ray intersecting the boundary of the target environment may be taken from the position of the character to obtain an intersection point of the position of the character and the boundary of the target environment, a linear distance between the position of the character and the intersection point is calculated, and the calculated linear distance is used as the distance between the character and the target environment. In addition, the distance between the character and the target environment can be calculated by other methods, which is not limited in the application.
Further, a shortest distance between the character and the target environment boundary is calculated.
And obtaining the target position closest to the role on the boundary of the target environment based on the calculated shortest distance.
And setting the target position as position data of the analog sound source.
There are various methods for calculating the shortest distance between the character and the target environment boundary, for example, a plurality of rays intersecting the target environment boundary may be generated by taking the position of the character as a starting point, intersections of the plurality of rays of the position of the character and the target environment boundary are generated, the straight line distance between the position of the character and each intersection is calculated, the calculated shortest distance is taken as the shortest distance between the character and the target environment, and the position of the point with the shortest distance between the character and the target environment boundary is taken as the target position. In addition, the distance between the character and the target environment can be calculated by other methods, which is not limited in the application.
The target position is the position of the nearest point to the character on the boundary of the target environment, and the target position moves along with the movement of the character and changes along with the change of the position of the character.
In practical applications, in the case where the target position includes two or more positions, the virtual sound source may be set with the same position data as any one of the target positions.
Specifically, if two or more points closest to the character exist on the boundary of the target environment, and the distances between the two or more points and the character are equal, the positions of the two or more points closest to the character are all target positions, and since the distances between the character and the two or more target positions are equal, it is possible to set position data identical to the position of any one of the target positions for the virtual sound source, in which case the difference in target position selection does not affect the sound effect finally exhibited.
For example, assuming that the target environment boundary is a "concave" boundary, and there is a hidden centerline that can equally divide the "concave" boundary into two parts, when a character moves onto the hidden centerline in the concave area of the "concave" boundary, there are two or more points closest to the character on the target environment boundary, the positions of the two or more points closest to the character on the target environment are all target positions, one of the target positions is arbitrarily selected, and the virtual sound source is set with the same position data as the position of the target position.
Step S230: and setting the virtual sound source according to the position data of the virtual sound source.
Specifically, the virtual sound source may be a tone resource in the virtual game scene, and the types of the sound of the virtual sound source include multiple types, such as wind sound, rain sound, thunder sound, and the like, or may be a mixed sound of wind sound, rain sound, thunder sound, and the like, which may be determined according to the target environment and the game scene.
For example, if the target environment is a lawn, the sound of the virtual sound source may include a worm sound, a playing sound, and the like, and if the specific game scene is a barren lawn, the sound of the virtual sound source may be a worm sound, and if the specific game scene is a lawn suitable for step-down and picnic, the sound of the virtual sound source may be a mixed sound of a worm sound, a smiling sound, a playing sound, and a speaking sound; if the target environment is ocean, the virtual sound source may include wind sound, wave sound, and the like, and in the case that the specific game scene is ocean in sunny and clear, the sound of the virtual sound source may be wave sound, ship flute, and the like, or may be mixed sound including wave sound and ship flute, and in the case that the specific game scene is ocean with electric lightning, the sound of the virtual sound source may include mixed sound including lightning, wind sound, wave sound, and the like.
If the target environment is a train station, the sound of the virtual sound source may be speaking sound, whistling sound, broadcasting sound, etc., and when the specific game scene is a train station where a train arrives temporarily, the sound of the virtual sound source may include vendor speaking sound, crowd speaking sound and station broadcasting sound, and the volume ratio of the vendor speaking sound, crowd speaking sound and station broadcasting sound in the sound of the virtual sound source may be determined according to actual requirements, for example, the volume ratio of the station broadcasting sound in the sound of the virtual sound source is 40%, and the volume ratio of the vendor speaking sound and crowd speaking sound in the virtual sound source is 30%, which is not limited in the application.
The location data of the virtual sound source may include one or more, and the virtual sound source may likewise include one or more, which may be determined as the case may be, and the present application is not limited thereto.
The above embodiments are further described below with reference to specific examples.
For example, assuming that when a character enters a game scene, an initial character position is obtained, and four environment areas including a brook, a pasture, a bamboo forest and a flower field are further included on the game interface in the case that the initial character position is the center of the game interface, the brook environment area, the pasture environment area, the bamboo forest environment area and the flower field environment area are all target environment areas, and the boundaries of the brook environment area, the pasture environment area, the bamboo forest environment area and the flower field environment area are all target environment boundaries.

And setting the target position as position data of the analog sound source.
If the target position includes two or more positions, the target environment boundary may be converted to obtain a converted environment boundary; and calculating the distance between the character and the boundary of the conversion environment, and setting position data for the virtual sound source based on the calculated distance.
Specifically, if a ray passes through the target environment model and the target environment boundary of the target environment model to generate more than two intersection points, the target environment model is a female die type; if any ray passes through the target environment model and only generates two intersection points with the target environment boundary of the target environment model, the target environment model is a male model.
In the case where the target position includes two or more positions, the target environment model is a female model, and when determining the position data of the virtual sound source, the unique target position can be obtained by conversion between the female model and the male model. The method comprises the steps of converting a target environment model into a male model, extracting the boundary of the target environment model converted into the male model through edge extraction and other methods, obtaining a conversion environment boundary, calculating the distance between a character and the conversion environment boundary, and setting position data for a virtual sound source.

Various methods for calculating the shortest distance between the character and the boundary of the transformation environment may be referred to the above step S220, and will not be described herein.
For example, assuming that after edge extraction is performed on a target environment model, an M-type target environment boundary with a closed bottom is obtained, under the condition that a character is located in the target environment boundary, position data identical to the position of the character is configured for a virtual sound source, under the condition that the character is located outside the target environment boundary, the shortest distance between the character and the target environment boundary is calculated, and under the condition that a transverse ray passes through the target environment boundary, since more than two intersection points exist between the transverse ray and the target environment boundary, the target environment model is a female model, the target environment model is converted to obtain a convex model, and assuming that edge extraction is performed on the converted target environment model to obtain a rectangular shape of the converted environment boundary, the shortest distance between the character and the rectangular converted environment boundary is calculated, and position data of the closest position on the converted boundary is not configured for the virtual sound source.
