As shown in fig. 2, fig. 2 is a schematic flowchart illustrating a sound source setting method 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 a virtual scene of interest, such as a snow mountain, a lake, a sea, a street, an amusement park, and the like, which is not limited in this application. The method for determining the target environment may be various, and the method may be determined according to whether the distance between the role and the center of the environment area is greater than a preset threshold, where the environment area does not belong to the target environment when the distance between the role and the center of the environment area is greater than the preset threshold, and the environment area belongs to the target environment when the distance between the role and the center of the environment area is less than or equal to the preset threshold; when the character moves, the scene in the game interface is continuously changed along with the movement of the character, and the environment area presented in the game interface at the same time when the position of the character is obtained or in the same frame of picture can be used as the target environment, or the target environment can be determined by other methods.
The boundary is a landmark boundary for dividing the environment region, and may be an outer contour line of the environment region 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 position of the character can be the place and the direction of the character.
For example, suppose that three environment areas, namely a forest, a waterfall and a street, are set in a game, a character is located among the forest environment area, the waterfall environment area and the street environment area, and the distances between the character and the forest environment area, the waterfall environment area and the street environment area are equal to each other and are smaller than a preset threshold value, the forest environment, the waterfall environment and the street environment all belong to target environments, and the boundary of the forest environment area, the boundary of the waterfall environment area and the boundary of the street environment area 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 a set threshold value, the street environment does not belong to a target environment, the boundary of the street environment area does not belong to the boundary of the target environment, under the condition that the role is located at an intermediate 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 boundaries of the target environment.
in practical application, the target environment boundary and the role position can be obtained at regular time according to a preset time interval.
The preset time interval may be determined according to actual requirements, for example, the target environment boundary and the role position (n is an integer greater than or equal to 1) may be obtained n times per second, or the target environment boundary and the role position (x is an integer greater than or equal to 1) may be obtained once per x frames.
Step S220: and judging whether the role is in the target environment or not based on the target environment boundary and the role position, if so, executing step S221, and if not, executing step S222.
step S221: and setting the same position data as the character for the virtual sound source. After the position data identical to the character is set for the virtual sound source, the process proceeds to step S230.
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 the position data is set for the virtual sound source, the process proceeds to step S230.
For example, a coordinate system may be established based on the target environment, a central point in the target environment is used as a coordinate origin, a target environment boundary and a role position are represented in a coordinate form, a distance between the target environment boundary and the role position is calculated, if the distance between the target environment boundary and the role position is greater than a preset value, it is determined that the role is located outside the target environment, if the distance between the target environment boundary and the role position is less than the preset value, it is determined that the role is located in the target environment, and if the distance between the target environment boundary and the role position is equal to the preset value, it is determined that the role is 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 does not limit the method.
if the character is in the target environment, setting position data which is the same as the position data of the character for the virtual sound source, and if the character moves in the target environment, moving the virtual sound source along with the movement of the character; 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.
For example, the intersection point of the character position and the target environment boundary may be obtained by taking the character position as a starting point and making any ray intersecting the target environment boundary, the linear distance between the character position and the intersection point may be calculated, and the calculated linear distance may be used as the distance between the character and the target environment. In addition, the distance between the role and the target environment can be calculated by other methods, which is not limited in the present application.
Further, a shortest distance between the character and the target environment boundary is calculated.
and obtaining the target position which is closest to the role on the boundary of the target environment based on the calculated shortest distance.
Setting the target position as position data of the analog sound source.
The method for calculating the shortest distance between the character and the boundary of the target environment may be various, for example, several rays intersecting the boundary of the target environment may be made using the position of the character as a starting point, intersection points of several rays at the position of the character and the boundary of the target environment are generated, the linear distance between the position of the character and each intersection point 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 on the boundary of the target environment, which is the shortest distance from the character, is taken as the target position. In addition, the distance between the role and the target environment can be calculated by other methods, which is not limited in the present application.
The target position is a position of a point closest to the character on the boundary of the target environment, and the target position moves with the movement of the character and changes with the change of the position of the character.
in practical applications, in a case where the target position includes two or more positions, the same position data as any one of the target positions may be set for the virtual sound source.
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, the same position data as the position of any one of the target positions can be set for the virtual sound source, in which case, the difference in the selection of the target positions does not affect the finally presented sound effect.
for example, assuming that the target environment boundary is a concave-shaped boundary, and the concave-shaped boundary has a hidden central line which can equally divide the concave-shaped boundary into two parts, when the character moves to the hidden central line in the concave region of the concave-shaped boundary, two or more points closest to the character exist on the target environment boundary, the positions of the two or more points closest to the character on the target environment are target positions, one of the target positions is arbitrarily selected, and position data which is the same as the position of the target position is set for the virtual sound source.
Step S230: and setting a virtual sound source according to the position data of the virtual sound source.
Specifically, the virtual sound source may be a timbre resource in a virtual game scene, and the type of the sound of the virtual sound source includes multiple types, such as wind sound, rain sound, thunder sound, and the like, or a mixed sound of wind sound, rain sound, and thunder sound, which may be determined according to the target environment and the game scene, which is not limited in this application.
for example, if the target environment is a lawn, the sound of the virtual sound source may include a worm sound, a joy sound, and the like, in the case where the specific game scene is a cool lawn, the sound of the virtual sound source may be a worm sound, and in the case where the specific game scene is a lawn suitable for stepping on green and picnics, the sound of the virtual sound source may be a mixed sound of the worm sound, the laughing sound, the joy sound, and the speech sound; if the target environment is an ocean, the virtual sound source may include wind sound, sea sound, and the like, and in the case that the specific game scene is an ocean in the world of clear sky, the sound of the virtual sound source may be the sea sound, ship whistle sound, and the like, or may be a mixed sound including the sea sound and the ship whistle sound, and in the case that the specific game scene is an ocean with lightning, the sound of the virtual sound source may include a mixed sound of thunder sound, wind sound, sea sound, and the like.
If the target environment is a train station, the sound of the virtual sound source may be speech sound, whistling sound, broadcast sound, and the like, and when the specific game scene is the train station where no train arrives, the sound of the virtual sound source may include vendor sound, crowd speech sound, and station broadcast sound, and the volume ratios of the vendor sound, the crowd speech sound, and the station broadcast sound in the sound of the virtual sound source may be determined according to actual requirements, if the volume ratio of the station broadcast sound in the sound of the virtual sound source is 40%, the volume ratios of the vendor sound and the crowd speech sound in the virtual sound source are both 30%, and the present application does not limit this.
The position data of the virtual sound source may include one or more, and the virtual sound source may also include one or more, which may be determined according to the specific situation, and the present application does not limit this.
The above embodiments will be further described with reference to specific examples.

Specifically, if a ray passes through the target environment boundary of the target environment model and the target environment model to generate more than two intersection points, the target environment model is a concave model; if any ray passes through the target environment boundary of the target environment model and the target environment model to generate only two intersection points, the target environment model is a convex model.
In the case where the target position includes two or more positions, the target environment model is a concave model, and when the position data of the virtual sound source is determined, the uniquely obtained target position can be obtained by conversion between the concave model and the convex model.
