Description

Technical Field

[0001] This application relates to the field of game design technology, and in particular to a method and apparatus for switching audio modes in a game scene. Background Technology

[0002] In game scenarios, sound effects are an essential component. To provide players with a better gaming experience, 3D audio modes are widely used in game scene sound effects, such as gunshots and footsteps, thereby achieving the most realistic simulation of sound.

[0003] In games, sound must respond to player actions. To ensure recorded audio clips function effectively in interactive environments, switching between 3D and 2D audio modes is necessary. For example, specific instruments might be played in certain situations. When a player enters a cave, the entrance uses 3D audio mode to play music, while 2D audio mode is used at other times. Typically, 3D audio mode adjusts the audio playback based on the player's distance from the sound source, while 2D audio mode plays the audio according to a pre-defined setting regardless of the player's position.

[0004] In related technologies, the function of enabling or disabling the relative path of the listener in the audio tool can be used to switch between 3D audio mode and 2D audio mode at will. However, this switching of audio mode can only be applied to a single type of music effect. For example, if you want to set the 3D audio mode, you need to disable the 2D audio mode in the audio tool. For the same sound source in a game scene, especially for music, it is not possible to switch between 2D audio mode and 3D audio mode at will, so the audio in the game scene does not achieve the expected effect, which affects the player's gaming experience. Summary of the Invention

[0005] In view of this, this application provides a method and apparatus for switching audio modes in a game scene. The main purpose is to solve the problem that the existing technology cannot achieve arbitrary switching between 2D audio mode and 3D audio mode for the same sound source, especially music, in a game scene, so that the audio in the game scene does not achieve the expected effect.

[0073] The invention will now be discussed with reference to several exemplary embodiments. It should be understood that these embodiments are described merely to enable those skilled in the art to better understand and thus implement the invention, and are not intended to imply any limitation on the scope of the invention.

The term "based on" is to be interpreted as "at least partially based on". The terms "one embodiment" and "an embodiment" are to be interpreted as "at least one embodiment".

[0075] In the process of switching audio modes in game scenes, the relevant technology allows for arbitrary switching between 3D and 2D audio modes by enabling or disabling the listener relative path function in the audio tool. However, this audio mode switching can only be applied to a single type of music effect. For example, if you want to set the 3D audio mode, you need to disable the 2D audio mode in the audio tool. For the same sound source in a game scene, especially for music, it is not possible to arbitrarily switch between 2D and 3D audio modes, which makes the audio in the game scene not achieve the expected effect and affects the player's gaming experience.

[0076] To address this issue, this embodiment provides a method for switching audio modes in a game scene, such as... Figure 1 As shown, the method includes the following steps:

[0077] 101. Create an audio switching container and import audio files representing different game scenes into the audio switching container.

[0078] The primary role of audio in video games is to create atmosphere and enhance the player's emotional experience. For example, dissonant long notes in string instruments are often used to foreshadow upcoming events, while the roar of an orchestra often abruptly overshadows the event when it suddenly occurs. Players are active participants in games, directly influencing the game's content and visuals, and even if a player plays the same game repeatedly, each playthrough will be different.

[0079] Typically, changes to object states in a game scene can be triggered using global events. For example, a character walking can be triggered by a walking event, and a character launching a skill can be triggered by a launching event. Considering the different parameters used for object states, changes to object states may involve audio switching. For instance, in a ground-walking scene, different ground types and materials result in different audio when the character walks. The audio for the corresponding walking event needs to be switched based on the ground type. For example, for a gravel ground type, the character's footsteps will produce corresponding gravel-like audio. Here, an audio switching container can be created to integrate the audio information needed in different game scenes. Specifically, depending on the game scene to which the object state is applied, the audio switching container can import audio files for different game scenes. For example, if the object state is applied to Preset1, Preset2, and Preset3 game scenes, the audio switching container can be used to set the associated audio files for each game scene: a Rock audio file can be played when Preset1 is selected, a Jazz audio file when Preset2 is selected, and a Classical audio file when Preset3 is selected.

[0080] Furthermore, to make it easier for the game engine to associate global events in the game scene with audio files, it can also set an identifier for the audio files in the audio switching container to associate with the scene change information based on the scene change information corresponding to the global event. Specifically, the identifier of the audio file can be set according to the type of ground material changed in the scene. For example, if the ground material is marble, a marble file identifier can be set, and if the ground material is gravel, a gravel file identifier can be set. It can also be set according to the type of skill changed in the scene. For example, if the skill type is a control skill, a control skill file identifier can be set, and if the skill type is a combo type, a combo type file identifier can be set.

[0081] The execution entity in this embodiment can be an audio mode switching device or equipment in the game scene, which can be configured on the server side of the audio engine. The planner can configure the corresponding audio information according to the global events in the game scene. By creating an audio switching container and importing audio files that express different game scenes into the audio switching container, the audio switching container can switch to play the audio of the corresponding game scene when a global event is triggered.

[0082] 102. Set two different sub-tracks for the audio switching container, put the same audio segments from the audio file into the two different sub-tracks respectively, and specify the state of the target object used in the game scene in the two different sub-tracks respectively.

[0083] Normally, an audio clip can be output and played as a single audio track. However, each audio clip may have different audio modes. In order for audio clips to play different audio modes, two different sub-tracks can be set for the audio switching container. When a sub-track of an audio clip is played, one audio mode will be output and played. The other audio modes will not be discarded, but will be switched according to the change of the object's state.

[0084] It should be noted that the two different sub-tracks here are mainly used for switching between different audio modes, including a sub-track for the first audio mode and a sub-track for the second audio mode. The first audio mode and the second audio mode can be 3D audio mode and 2D audio mode, respectively. Compared with 2D audio mode, 3D audio mode has the characteristics of a larger sound field, more accurate sound positioning, and more realistic sound, allowing players to clearly feel the extension in the audio clips and have a better music effect. Specifically, the two audio sub-tracks can be set in the audio track properties to specify the target object state used in the game scene and the audio clips associated with the target object state. The audio modes in the two audio sub-tracks can be switched using the toggle button / switch during the playback of the audio clips.

[0085] 103. In response to the audio mode switching caused by the change to the target object state, the target object state specified by the two different sub-tracks is called respectively to determine the target audio segment in the audio file associated with the target object state.

[0086] The audio mode switching can be automatically triggered by changes in the state of the target object. For example, the sound effect of the player character entering the secret room in the game scene will change when the sound of the ground being stepped on changes. Alternatively, it can be set to be triggered at a time based on changes in the state of the target object, such as triggering an explosion sound effect 10 seconds after the player enters the explosion scene.

[0087] Typically, the audio engine identifies changes in the state of objects in the game scene in real time based on global events. For example, it identifies whether the player is awake or whether the player is on or underwater. When the state of the target object changes, corresponding audio changes will occur. Since the two different audio subtracks specify the object state and the associated audio segments during the setup process, the target audio segment in the associated audio file of the target object state can be determined based on the association set on the audio subtrack, and the target audio segment can be assigned to the corresponding changed target object state.

[0088] 104. For the state of the target object, control the target audio segment to switch the sub-tracks of the first audio mode and / or the sub-tracks of the second audio mode according to the preset track switching rules.

[0089] In this embodiment, considering the transition between audio segments, the audio track switching rules can use default rules or custom rules. Specific rules can include at least one of audio switching time, audio switching method, and audio switching position. For example, for game scenarios with time requirements, an audio switching time rule can be used. The switching of audio tracks can be controlled by setting a time range for audio switching. Specifically, when the game running time reaches the audio switching time, the target audio segment is controlled to switch between sub-tracks of the first audio mode and / or the second audio mode according to the set time range. Here, the audio mode can be controlled to switch before, within, or after the set time range. This can be set according to the actual game scenario. For example, when the game runs for 30 minutes, coins are distributed to the player. The target audio segment can be the sound of coins falling, with a sound effect duration set to 10 seconds. At this time, the audio mode is controlled to switch from the 2D audio mode sound effect to the 3D audio mode coin falling sound, and the sound effect lasts for 10 seconds after the coin falling is triggered. For game scenarios with effect requirements, audio switching effects can be used. The rules for audio track switching are based on setting audio switching effects. Specifically, when the game runs for a certain period, the system determines whether the audio track should switch to a sub-track of the first audio mode or the second audio mode based on the set effects. Taking the coin-dropping sound as an example, the system can use immediate switching or gradual sound switching effects to control the audio mode to switch immediately from the 2D audio mode sound effect or gradually switch to the 3D audio mode coin-dropping sound. For game scenes with spatial requirements, the rules for audio switching position can be used. The system determines whether the game runs for a certain period, determines whether the audio track should switch to a certain position based on the set spatial position. Here, the spatial position can be the player's position in the game scene. For example, if the player is in water, the system can combine the water sound effects to control the audio mode to switch from the 2D audio mode sound effect to the 3D audio mode coin-dropping sound. The rules for audio track switching are not limited here.

[0090] In practical applications, game scenarios involve various environmental sound effects, including natural, cultural, and magical sound effects. Natural sound effects typically refer to various sounds of nature, including weather sounds such as wind, rain, thunder, and lightning, as well as sounds emanating from specific areas, such as the flow of lava in a volcano, the babbling of a stream, waves crashing on the shore, and the calls of various animals in nature. Cultural sound effects refer to environmental sounds produced by human civilization, such as the sound of reading in a school, the sound of keyboard typing in an office, and discussions. Magical environments refer to virtual world scenes that do not objectively exist but are composed of abstract human-shaped subjects and objects, such as the sky, the underworld, and an underwater palace. Specifically, during the switching of audio modes in a game scene, the system can also acquire environmental sound effects from the game scene, determine the target audio mode suitable for the current audio segment in the game scene based on the environmental sound effects, and control the current audio segment to play using the target audio mode. For example, when the player encounters a natural environment, a 3D audio mode is used to represent different seasons and regions; when the player encounters a human environment, a 2D audio module is used to represent the sounds made by the human activity; when the player encounters a magical environment, a combination of 2D and 3D audio modes is used to represent the characteristics of the scene. 3D audio mode can be used for scenes that create atmosphere, while 2D audio mode can be used for music scenes.

[0091] The audio mode switching method in the game scene provided in this application embodiment, compared with the existing method of arbitrarily switching between 3D and 2D audio modes by enabling or disabling the listener relative path function on the audio tool, creates an audio switching container, imports audio files representing different game scenes into the audio switching container, sets two different sub-tracks for the audio switching container, places the same audio segments from the audio files into the two different sub-tracks respectively, and specifies the target object state used in the game scene in the two different sub-tracks respectively. In response to the audio mode switching caused by changing to the target object state, the target object state specified by the two different sub-tracks is called respectively, the target audio segment in the audio file associated with the target object state is determined, and for the target object state, the target audio segment is controlled to switch the sub-track of the first audio mode and / or the sub-track of the second audio mode according to the preset audio switching rules. Thus, for the same sound source in the game scene, especially music, it is possible to achieve arbitrary switching between the first audio mode and the second audio mode, so that the audio in the game scene can better match the camera, bring an immersive music experience, and improve the audio playback effect in the game scene.

[0092] As a refinement and extension of the specific implementation of the above embodiments, and to fully illustrate the specific implementation process of this embodiment, this embodiment provides another method for switching audio modes in a game scene, such as... Figure 2 As shown, the method includes:

[0093] 201. Define a state interface for responding to global events in the game scene, and create an audio switching container based on the state interface.

[0094] Since game scenes do not have a fixed timeline and event sequence, it is impossible to know how long a player character stays in a certain game scene or when an event is triggered. Therefore, game audio also needs to be connected to the game scene and provide timely feedback.

[0095] Understandably, considering that the state of objects in the game scene will change with global events, for example, the player may step on different materials or trigger different types of skills, we define a state interface that responds to global events in the game scene, create an audio switcher based on the state interface, and then use the audio switcher to associate different object states with audio clips, so that each object state has a unique sound effect.

[0096] 202. Set audio segments associated with different object states in the game scene, summarize the audio segments into audio files that express different game scenes, and import the audio files that express different game scenes into the audio switching container.

[0097] In this embodiment, the audio segment associated with the object state can be determined based on the change information of the object state. If the change information of the object state involves the change of footsteps when the player enters the game scene, the audio segment associated with the object state is the sound effect of stepping on the corresponding ground material. If the change information of the object state involves the player's heart rate accelerating when entering the game scene, the audio segment associated with the object state is the sound effect of the character's heartbeat.

[0098] Specifically, we can obtain global events that trigger object state changes in the game scene, set audio clips associated with different object states in the game scene based on the global events, set the playback sequence of the audio clips according to the order of events that trigger object state changes in the game scene, summarize the audio clips into audio files representing different game scenes according to the playback sequence, and import the audio files representing different game scenes into the audio switching container. Here, object state changes can be from a static state to a walking state, from a walking state on material A to a walking state on material B, from a static state to a skill firing state, etc. Since changes in global events will cause object state changes, in the process of associating different object states with audio clips, considering that object states have matching sound effects in real life, we can extract the sound effects in real life as the audio clips associated with the object states. For example, the walking event of a game character will trigger the object state to change to a walking state, and the walking event needs to be associated with the audio clip of footsteps; the firing event of a game character will trigger the object state to change to a firing state, and the firing event needs to be associated with the audio clip of skills.

[0099] 203. Set two different sub-tracks for the audio switching container, put the same audio segments from the audio file into the two different sub-tracks respectively, and specify the state of the target object used in the game scene in the two different sub-tracks respectively.

[0100] In this embodiment, to better immerse players in the game world, the audio mode corresponding to the current audio segment is determined based on the environmental sound effects required to transition to the new object state in the game scene within two different sub-tracks. If the transition requires artificially created and enhanced sound effects, or sound effects for UI clicks or action feedback, a 3D audio mode can be used to play the audio segment. If the transition involves dialogue from a story animation or quick voice lines, a 2D audio mode can be used. If the transition involves music from a story scene, the choice between 3D and / or 2D audio modes can be determined based on the type of music. Here, while using 2D audio mode, the 3D audio mode can be randomly switched to play the audio segment along with the audio rhythm, thereby avoiding a monotonous audio mode in the game scene and improving the audio playback effect.

[0101] Furthermore, considering the diversity of audio segments, audio sub-tracks can be set for different audio dynamics switching. For example, if an audio segment contains three guitar parts with different dynamics and a blank part, four audio sub-tracks can be set for different audio dynamics switching.

[0102] 204. Receive calls from the game engine to initiate global events in the game scene, and monitor changes in the state of objects in the game scene based on the global events in the game scene.

[0103] During the game design process, the game engine and the audio engine transmit global events in the game scene through game calls. For each game call, the game engine generates a corresponding global event in the game scene and sends the global event to the audio engine so that the audio engine can output different audio effects adapted to the game scene, such as audio effects adapted to the environment in the game scene, or music effects adapted to magic in the game scene.

[0104] It is understandable that global events may occur as the state of objects in the game scene changes. Each global event has an object type and an event type when it is created. For example, when creating a global event to receive an item, the object type of this global event is the item type and the event type is the receiving type. Here, we can monitor changes in the state of objects in the game scene based on the object type and event type of the global event.

[0105] 205. In response to the audio mode switching caused by the change to the target object state, the target object states specified by the two different sub-tracks are invoked respectively.

[0106] 206. Utilize the mapping relationship between object states in the game scene and audio segments in the audio file to determine the target audio segment in the audio file associated with the target object state.

[0107] In this embodiment, the mapping relationship between object states and audio segments in audio files can be one-to-one or many-to-one. That is, each object state corresponds to at least one audio segment, and multiple object states may correspond to the same audio segment. Alternatively, object states can be set to have no sound effects. This mapping relationship can be configured customwise or generated automatically by an audio engine. The audio engine can identify uploaded audio files and, based on the identified audio type, rhythm, and other information, perform audio matching with the object states in the game scene. This establishes an association between audio files suitable for the object states in the game scene, resulting in a mapping relationship between objects in the game scene and audio segments in the audio files. Considering that audio segments in the audio files may have the same or similar musical styles, this mapping relationship can be adjusted later based on the actual adaptation effect.

[0108] 207. For the state of the target object, control the target audio segment to switch the sub-tracks of the first audio mode and / or the sub-tracks of the second audio mode according to the preset track switching rules.

[0109] Here, the target object state is used to determine the audio clip to be played and the audio mode selected for that audio clip. For example, when the current target object state is triggered in the game scene, music clip A is played using the sub-track of the first audio mode. When the next target object state is triggered in the game scene, music clip B is played using the sub-track of the second audio mode. This process can achieve synchronized playback of the object state and the audio clip. At the same time, as the object state changes, the audio clip may also switch playback synchronously, thereby ensuring that the sound effects created by the game scene can meet the player's expectations.

[0110] Furthermore, to improve the playback effect of the audio clip, before this step, the spatial position information of the target object's state in the game scene can be obtained. Based on this spatial position information, a three-dimensional spatial positioning effect is set for the target audio clip, and an audio attenuation curve is added for the target object's state. The attribute parameters of the audio attenuation curve are then adjusted using the three-dimensional spatial positioning effect. Here, the audio attenuation curve is typically used to simulate the natural attenuation of a signal as it moves away from the listener. A series of curves can be used to map attributes such as volume to specific distance values. Using these curves, more detailed distance-based attenuation behavior can be created for sounds and audio objects. Specifically, in the process of adjusting the attribute parameters of the audio attenuation curve using the three-dimensional spatial positioning effect, an audio attenuation curve can be added for the target object's state. The three-dimensional spatial positioning effect describes the distance and volume changes between the sound source and the listener in the target object's state, and the attribute parameters of the audio attenuation curve are adjusted according to these distance and volume changes. In a game scene, the distance between the game object emitting the sound and the listener will determine the volume. When a sound is emitted, the distance can be determined by comparing the three-dimensional coordinates of the sound source and the listener relative to each other. When the sound source moves away, the most obvious change in the sound is that the volume will decrease. The default audio attenuation curve will affect the volume.

[0111] It is understandable that the distance unit of the characters in the game scene, as an attribute parameter of the audio attenuation curve, will also affect the volume change information. For example, if the protagonist in the game scene is an ant, the distance unit may be millimeters, and the magnitude of the volume change information is also small. However, for a game about interstellar travel, the distance may be light-years, and the magnitude of the volume change information is correspondingly larger.

[0112] Furthermore, regarding the pre-setting process of audio switching rules, prior to this step, audio track switching rules applicable to the sub-tracks of the first audio mode and / or the second audio mode in the target audio segment can be generated based on the target object state. Specifically, the transition conditions corresponding to the target object state can be obtained, and the transition information for switching to the target audio segment can be determined based on the transition conditions. The audio track switching rules applicable to the sub-tracks of the first audio mode and / or the second audio mode in the target audio segment can be generated using the transition information for switching to the target audio segment. Here, the transition conditions mainly include transition time and transition volume. For the transition time, the audio segment can be set to switch suddenly or gradually. For the transition volume, the volume of the audio segment can be set to gradually increase to a set volume or directly reach a set volume.

[0113] Furthermore, as Figure 1 and Figure 2In a specific implementation of the method, this application provides a device for switching audio modes in a game scene, such as... Figure 3 As shown, the device includes: a creation unit 31, a setting unit 32, a determination unit 33, and a switching unit 34.

[0114] The creation unit 31 can be used to create an audio switching container and import audio files representing different game scenes into the audio switching container;

[0115] The setting unit 32 can be used to set two different sub-tracks for the audio switching container, put the same audio segments in the audio file into the two different sub-tracks respectively, and specify the target object state used in the game scene in the two different sub-tracks respectively. The two different sub-tracks include a sub-track of the first audio mode and a sub-track of the second audio mode.

[0116] The determining unit 33 can be used to respond to the audio mode switching caused by the change to the target object state, respectively call the target object state specified by the two different sub-tracks, and determine the target audio segment in the audio file associated with the target object state.

[0117] The switching unit 34 can be used to control the target audio segment to switch between the sub-tracks of the first audio mode and / or the sub-tracks of the second audio mode according to the preset track switching rules, based on the state of the target object.

[0118] The audio mode switching device for game scenes provided in this invention, compared with the existing method of achieving arbitrary switching between 3D and 2D audio modes by enabling or disabling the listener relative path function on the audio tool, creates an audio switching container, imports audio files representing different game scenes into the audio switching container, sets two different sub-tracks for the audio switching container, places the same audio segments from the audio files into the two different sub-tracks respectively, and specifies the target object state used in the game scene in the two different sub-tracks respectively. In response to the audio mode switching caused by changing to the target object state, the target object state specified by the two different sub-tracks is called respectively, the target audio segment in the audio file associated with the target object state is determined, and for the target object state, the target audio segment is controlled to switch the sub-track of the first audio mode and / or the sub-track of the second audio mode according to the preset audio switching rules. Thus, for the same sound source in the game scene, especially music, arbitrary switching between the first audio mode and the second audio mode can be achieved, so that the audio in the game scene can better match the camera, bring an immersive music experience, and improve the audio playback effect in the game scene.
