Description

Technical Field

[0001] This application relates to the field of game development technology, and in particular to a method, apparatus, storage medium, and computer device for generating game ambient sound. Background Technology

[0002] In game development, players in virtual game scenes acquire ambient sound through surrounding acoustic recognition. Currently, methods for acquiring game ambient sound typically involve dynamically adjusting environmental sound absorption parameters based on the degree of enclosure and boundary materials of the space where the character is located to generate ambient sounds with different effects. However, relying solely on enclosure and dynamic boundary material adjustments cannot meet the need for real-time assessment of the surrounding environment's sound absorption when players move, turn, or enter caves, indoor spaces, or semi-open spaces. Furthermore, it cannot avoid the situation where environmental judgment is one-sided due to using only unidirectional detection, resulting in inconsistent sound parameters and affecting the realism of the sound, thus significantly reducing the accuracy and effectiveness of game ambient sound generation.

It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0025] This application provides a method for generating game ambient sound, such as... Figure 1 As shown, the method includes: 101. Construct the sound cage of game characters in the game environment.

[0026] In this embodiment, the current execution terminal, as the entity responsible for generating game environment sound, can be a game operating terminal, such as a mobile phone or handheld game console, or a game server, such as a cloud server; this embodiment does not impose specific limitations. Furthermore, the game in this embodiment is applicable to massively multiplayer online games, offline single-player games, etc. Game characters refer to virtual objects that can be manipulated by game players in the game, including but not limited to human-shaped characters, animal-shaped characters, and various scene object-shaped characters; this embodiment does not impose specific limitations. The game environment can be an environment created from various spaces or scenes, including but not limited to indoor spaces, semi-open spaces, caves, towns, forests, etc.; this embodiment does not impose specific limitations.

[0027] It should be noted that a sound cage is used to characterize the effective propagation range of sound in the game environment. It can be constructed based on the position of the game character in the scene. Different game characters can each construct a corresponding sound cage, which is updated as the game character moves, so as to constrain the propagation of sound within an effective sound absorption range.

[0028] In another embodiment of this application, for further definition and explanation, the step of constructing the sound cage of the game character in the game environment includes: The head-related position point of the game character is determined based on a preset distance range; Using the camera's horizontal direction as a reference, the local orientation is converted to the world orientation of the game environment; The acoustic cage is constructed based on the head-associated location point and the world direction.

[0029] To ensure effective sound absorption within a specific range and to allow the sound to change with the movement of the game character, thereby enhancing sound realism, the sound cage is constructed by first determining the head-related position point of the game character. Specifically, the center of the sound cage is created using the vicinity of the game character's head. The preset distance range can be set based on the size of the game character's model, such as any distance between 0 cm and 50 cm. Correspondingly, starting from the head, the determined head-related position point can be any position point extending outwards from the head, ears, visual camera, or listening point within the preset distance range; this is not specifically limited in this embodiment. In a specific example, when determining the head-related position point, a position point on the top of the head can be determined by offsetting the capsule's half-height vertically upwards from the world position of the controlled character's capsule component; this is not specifically limited in this embodiment either.

[0030] Furthermore, when constructing the sound cage, the game character's horizontal perspective is converted. That is, using the camera's horizontal direction as a reference, the local orientation is converted to the world orientation of the game environment. This results in a sound cage centered on the character's listening position, encompassing a 24-directional detection range that rotates with the character's horizontal perspective. This includes horizontal, upward, high-angle, and downward directions. The horizontal direction comprises eight directions, covering approximately 29 degrees left and right in front, 61 degrees left and right in front, 119 degrees left and right behind, and 151 degrees left and right behind relative to the viewing angle. The upward direction comprises eight directions, adding approximately 26 degrees of elevation to the above horizontal directions. The high-angle direction comprises four directions, covering four oblique directions with an elevation angle of approximately 42 degrees: left front, right front, left rear, and right rear. The downward direction comprises four directions, covering four oblique directions with a depression angle of approximately 42 degrees: left front, right front, left rear, and right rear. This covers the character's front, back, left, right, side rear, upward, and downward directions. Furthermore, the world orientation of the game environment refers to the globally fixed coordinate axis reference during game time, with the scene mesh center at the origin (0,0,0). It is unaffected by character or model rotation, and the world position and orientation of all objects are referenced to the fixed axis of the world orientation. Therefore, converting the local orientation to the world orientation ensures that the constructed sound cage does not follow camera pitch or roll changes. Finally, the sound cage is constructed based on the head-related position point and the world orientation. That is, starting from the head-related position point, it can be extended in the world orientation to obtain an enclosure used for sound absorption judgment.

[0031] 102. Determine the boundary endpoints in multiple directions based on the center point of the acoustic cage, and perform audio collision detection based on the boundary endpoints to determine the physical material of the collision.

[0032] In this embodiment, after constructing the sound cage corresponding to the game character, the boundary endpoints in multiple directions are determined using the center point of the sound cage. The center point of the sound cage can be the center position calculated in three-dimensional space with the sound cage as the reference point. These multiple directions can represent all world directions within the game environment. Then, the boundary endpoints at a preset propagation distance are detected using ray detection. Preferably, the preset propagation distance is 2000 cm, but this embodiment does not impose a specific limitation. Furthermore, spectral collision detection is performed according to the determined boundary endpoints. This can be done using an audio environment collision detection component. When an audio collision is detected, it indicates the presence of a collider affecting sound propagation. Therefore, the collision physical material of the collider is obtained through a query method.

[0033] In another embodiment of this application, for further definition and explanation, the step of determining the boundary endpoints in multiple directions using the center point of the acoustic cage includes: Starting from the center point, voxel and / or scene boundary detection is performed along the world direction; If the voxel and / or the scene boundary are detected, the boundary endpoint is determined based on the hit voxel and / or the hit scene boundary. If the voxel and / or the scene boundary are not detected, the maximum detection distance is determined as the boundary endpoint.

[0034] To assess the sound propagation effect from multiple directions and avoid the biased nature of sound propagation in the environment, when determining the boundary endpoints in multiple directions, the center point of the sound cage is first used as the starting point, and voxel and / or scene boundary detection is performed along the world direction. This detection can be performed using the ray detection component of the world query subsystem, while simultaneously setting the detection range, such as within 2000 cm.

[0035] In one specific embodiment, if the voxel and / or the scene boundary are detected, it indicates that sound propagation within the detection range is affected by the voxel or scene boundary. Therefore, the boundary endpoint is determined based on the detected voxel and / or the detected scene boundary. Conversely, if the voxel and / or the scene boundary are not detected, it indicates that sound propagation within the detection range is not affected by the voxel or scene boundary. Therefore, the maximum detection distance is determined as the boundary endpoint. In this case, the maximum detection distance can be set based on different game scenarios, and this application embodiment does not impose specific limitations.

[0036] It should be noted that after determining the boundary endpoint, information such as direction, endpoint, distance from center to endpoint, and whether it is blocked by the boundary is recorded according to the direction number. For the direction of the boundary endpoint that has been detected, the straight-line connectivity judgment of the world query subsystem can also be used to check whether there is a straight-line connection between the hit boundary point and the player character position in the voxel space, and the judgment result is recorded as the boundary connectivity.

[0037] In another embodiment of this application, for further definition and explanation, the step of performing audio collision detection based on the boundary endpoint to determine the collision physical material includes: When the center point is valid, collision detection is performed starting from the boundary endpoint and according to the target direction and the first distance. When a collider is detected, the collision physical material of the collider is queried.

[0038] To achieve sound absorption detection and improve the realism of sound propagation, the audio collision detection process first determines whether the center point of the sound cage is valid. This can be determined by checking the existence of the center point or whether it enters other scene object models; this embodiment does not specify a particular method. Furthermore, when the center point is valid, a short-range extended detection is performed starting from the boundary endpoint. This involves collision detection based on the target direction and a first distance. The target direction can be the same as the direction of the detection boundary endpoint, and the first distance, as a short-range detection requirement, can be set to 100 centimeters to initiate an asynchronous linear detection.

[0039] In one specific embodiment, when a collider is detected, it indicates the presence of an object that can absorb sound; therefore, the physical material of the collider can be queried.

[0040] In another embodiment of this application, for further definition and explanation, the steps also include: If the distance between the colliding object and the center point is less than a preset distance threshold, then collision detection is performed according to the target direction and the second distance to re-detect the colliding object.

[0041] To improve the stability of material sampling when players are close to walls, caves, or narrow spaces, thereby enhancing the realism of sound propagation, a distance threshold is preset as the basis for extending the distance. That is, when the distance between the colliding object and the center point is less than this preset distance threshold, it indicates that the distance is too close, and collision detection is performed according to the extended second distance. At this time, the second distance can be set to 500 cm or 1000 cm, which is greater than the first distance. This application embodiment does not make specific limitations.

[0042] In another embodiment of this application, if no collider is detected, it indicates that there is no material that effectively absorbs sound in this target direction. Therefore, collision detection can be performed in the next direction further away or the detection can be terminated. This embodiment of the application does not make specific limitations.

[0043] 103. Based on the sound absorption coefficient extracted from the collision physical material and the detection direction, perform material sound absorption aggregation to obtain sound rendering parameters, and generate game ambient sound based on the sound rendering parameters.

[0044] In this embodiment, since materials in the physical world can characterize the properties of objects, such as hardness and brightness, different materials have different effects on sound propagation and absorption. Therefore, to make the sound effects in the game environment more realistic, the sound absorption coefficient is extracted according to the physical materials of the collision, as the sound absorption contribution of sound propagation in this direction. Furthermore, material sound absorption aggregation is performed based on the sound absorption coefficient and the detection direction. Here, the detection direction can be the effective direction of the detected colliding object, and can be multiple or just one; this embodiment does not specifically limit this. The sound rendering parameters obtained after material sound absorption aggregation are used to characterize the relevant parameters for rendering sound in different directions, including but not limited to volume gain, stereo spread, distance attenuation, and sound source orientation, to generate the final game environment sound based on the sound rendering parameters.

[0045] In another embodiment of this application, for further definition and explanation, the step of performing material sound absorption aggregation based on the sound absorption coefficient extracted from the collision physical material and the detection direction to obtain sound rendering parameters includes: Read the sound absorption coefficient of the physical material involved in the collision; Based on the world direction, multiple detection directions are determined, and the spatial openness is converted for the collision distances corresponding to the multiple detection directions to obtain the spatial openness percentage. Sound rendering parameters are generated based on the percentage of spatial openness and the detection direction.

[0046] To meet the sound absorption requirements of different materials and ensure realistic sound propagation, the sound absorption coefficient of the colliding physical materials is read. This sound absorption coefficient characterizes the sound absorption capacity of different colliding materials. The sound absorption coefficient is derived from the sound absorption coefficient field corresponding to the colliding physical material in the audio material configuration table and can be written during physical material generation or initialization. Therefore, different walls, stone walls, wood, fabric, and other boundaries can be configured with different sound absorption capacities. Furthermore, the detection direction can be determined based on the world direction. This can be done by determining the direction of the detected colliding object within the world direction; this embodiment does not impose specific limitations. Next, the spatial openness is converted from the collision distances corresponding to multiple detection directions to obtain a spatial openness percentage. This can be done based on the Sabine reverberation formula, the conversion of distances in real-world environments such as rooms, or by calling conversion components in game engines, such as the UE series game engine, to perform parameter conversion and obtain a spatial openness percentage; this embodiment does not impose specific limitations.

[0047] In one specific embodiment, the environment component can periodically update spatial audio information, such as triggering an update every 0.2 seconds. After calling the sound cage through the game blueprint and performing the corresponding collision detection, it is grouped according to the left, right, front, back, up, down and other directions to determine the detection direction. The distance of each direction is converted into a percentage of spatial openness, and the corresponding physical material is retained.

[0048] It should be noted that after obtaining the percentage of spatial openness, sound rendering parameters are generated by combining the detection direction. That is, the sound absorption coefficients of the physical materials extracted after effective extended collision detection are averaged to generate sound rendering parameters.

[0049] In a specific example, when generating sound rendering parameters based on the detection directions, specifically for the six detection directions (left, right, front, back, up, and down), the spatial openness of these six directions can be averaged and multiplied by a distance weight to obtain the overall spatial size parameter. The smaller openness among the left, right, front, back, and up directions is selected, and the range of 15 to 100 is mapped to 0 to 100 to obtain the front reflection delay parameter. This ensures that the earlier the reflection is, the more pronounced the muffled sound is, especially in narrower spaces. Based on the openness of the left and right sides and the front and back directions, reflected sound images and ambient sound images are calculated separately. The more enclosed the lateral areas, the more concentrated the reflections and ambient sound distribution in the corresponding directions. The base width is calculated based on the larger value of the left and right openness, and the reflection width is calculated by combining the openness of the left and right, front and back directions and the type of obstruction, making reflections wider in open spaces and narrower in enclosed spaces. Calculate the absolute values ​​of the differences in left-right, front-back, and vertical openness, and take the smaller value as the spatial orientation difference parameter to suppress abrupt sound image jumps caused by spatial imbalances. Finally, read the physical material type for each hit direction, assign weights to different materials, and calculate the average to obtain the material absorption parameter. Combine the above parameters into the sound rendering parameters.

[0050] In another embodiment of this application, for further definition and explanation, the step of generating game ambient sound based on the sound rendering parameters includes: The sound rendering component is invoked, and game ambient sounds corresponding to the sound rendering parameters in different directions are generated based on the sound rendering component.

[0051] To ensure realistic sound generation, the sound rendering component is first invoked during rendering to control the generation of game ambient sounds in conjunction with sound rendering parameters. At this stage, the rendering of game ambient sounds is only written to the sound rendering parameters when the values ​​relative to the last saved sound rendering parameters change. Furthermore, reflection effect resources on the spatial reflection bus are set through an audio intermediate component to produce realistic sound effects such as reverberation during rendering. Additionally, during sound rendering, for different materials, higher sound absorption coefficients result in stronger high-frequency attenuation and ambient muffled sound; smaller overall space dimensions result in shorter early reflection delays, narrower reflection widths, and a stronger sense of spatial immersion. When the space is relatively open or has minimal directional differences, a wider reflection distribution and weaker muffled sound processing can be used to create a continuous transition between outdoor, semi-open spaces, and cave interiors.

[0052] In a specific example, when a player controls their character to enter a cave from an open outdoor space, there are no collisions within 2000 cm in most directions outdoors, so the corresponding sound rendering parameters are 0. After entering the cave, collisions gradually occur from the sides, above, and diagonally behind the cave walls or ceiling. The sound absorption coefficients of materials such as stone are read, and the average sound rendering parameters are calculated. As the number of effective collision directions increases, the rendered audio is enhanced with high-frequency attenuation and environmental muffled sound, thus creating a continuous sound transition from open to enclosed space.

[0053] This application provides a method for generating game environment sound. Compared with the prior art, this application constructs a sound cage for the game character in the game environment, the sound cage being used to characterize the effective propagation range of sound in the game environment; determines boundary endpoints in multiple directions based on the center point of the sound cage, and performs audio collision detection based on the boundary endpoints to determine the collision physical material; performs material sound absorption aggregation based on the sound absorption coefficient extracted from the collision physical material and the detection direction to obtain sound rendering parameters, and generates game environment sound based on the sound rendering parameters, realizing that the sound is rendered along with the player character's movement, meeting the needs of sound absorption in different directions of the environment, improving the overall propagation effect of sound in the environment, thereby improving the realism of the game environment sound.

[0054] Furthermore, as a response to the above Figure 1 The implementation of the method shown in this application provides a device for generating game ambient sound, such as... Figure 2 As shown, the device includes: Component 21 is used to construct the sound cage of a game character in the game environment, wherein the sound cage is used to characterize the effective propagation range of sound in the game environment; The determination module 22 is used to determine the boundary endpoints in multiple directions based on the center point of the acoustic cage, and to perform audio collision detection based on the boundary endpoints to determine the collision physical material. The generation module 23 is used to aggregate the sound absorption coefficient extracted from the collision physical material and the detection direction to obtain sound rendering parameters, and generate game ambient sound based on the sound rendering parameters.

[0055] Furthermore, the construction module is specifically used to determine the head-related position point of the game character based on a preset distance range; using the horizontal direction of the camera as a reference, converting the local direction into the world direction of the game environment, the local direction including the horizontal layer direction, the diagonal upper layer direction, the high elevation angle layer direction, and the diagonal lower layer direction; and constructing the sound cage based on the head-related position point and the world direction.

[0056] Furthermore, the determining module is specifically used to perform voxel and / or scene boundary detection along the world direction starting from the center point; if the voxel and / or the scene boundary is detected, the boundary endpoint is determined based on the hit voxel and / or the hit scene boundary; if the voxel and / or the scene boundary is not detected, the maximum detection distance is determined as the boundary endpoint.

[0057] Furthermore, the determining module is specifically used to perform collision detection starting from the boundary endpoint and according to the target direction and the first distance when the center point is valid; when a collider is detected, the collision physical material of the collider is queried.

[0058] Furthermore, the determining module is also used to perform collision detection according to the target direction and the second distance if the distance between the colliding object and the center point is less than a preset distance threshold, so as to re-detect the colliding object.

[0059] Furthermore, the generation module is specifically used to read the sound absorption coefficient in the collision physical material, the sound absorption coefficient being used to characterize the sound absorption capability of different material collision bodies; determine multiple detection directions based on the world direction, and perform spatial openness conversion on the collision distances corresponding to the multiple detection directions to obtain a spatial openness percentage; and generate sound rendering parameters based on the spatial openness percentage and the detection directions.

[0060] Furthermore, the generation module is specifically used to invoke the sound rendering component and generate game ambient sounds corresponding to the sound rendering parameters in different directions based on the sound rendering component.
