Struct AudioSource 

pub struct AudioSource {
    pub audio: AssetHandle<AudioAsset>,
    pub playing: bool,
    pub looping: bool,
    pub volume: f32,
    pub pitch: f32,
    pub channel: AudioChannel,
    pub auto_play: bool,
    pub spatial: bool,
    pub max_distance: f32,
    pub attenuation: AttenuationModel,
    /* private fields */
}

AudioSource component for spatial audio playback.

Attach this component to an entity to enable audio playback. The audio system will automatically handle playback, looping, volume, pitch, and spatial audio based on the component’s configuration.

Fields

• audio: Reference to the audio asset to play
• playing: Whether the audio is currently playing
• looping: Whether the audio should loop when it finishes
• volume: Volume multiplier (0.0 = silent, 1.0 = full volume)
• pitch: Pitch multiplier (0.5 = half speed, 2.0 = double speed)
• channel: Audio channel for grouping and mixing
• auto_play: Whether to start playing automatically when spawned
• spatial: Whether to apply spatial audio (requires Transform)
• max_distance: Maximum distance for spatial audio attenuation
• attenuation: Distance-based volume falloff model
• sink_id: Internal audio sink ID (managed by audio system)

Examples

See module-level documentation for usage examples.

• volume: 1.0 (full volume)
• pitch: 1.0 (normal speed)
• channel: SFX
• auto_play: false
• spatial: false (non-spatial)
• max_distance: 100.0
• attenuation: InverseDistance
• sink_id: None

Examples

use goud_engine::ecs::components::AudioSource;
use goud_engine::assets::AssetHandle;
use goud_engine::assets::loaders::audio::AudioAsset;

let audio_handle: AssetHandle<AudioAsset> = AssetHandle::default();
let source = AudioSource::new(audio_handle);

assert_eq!(source.playing, false);
assert_eq!(source.volume, 1.0);
assert_eq!(source.pitch, 1.0);

pub fn with_volume(self, volume: f32) -> AudioSource

Sets the volume (0.0-1.0, clamped).

Examples

use goud_engine::ecs::components::AudioSource;
use goud_engine::assets::AssetHandle;
use goud_engine::assets::loaders::audio::AudioAsset;

let audio_handle: AssetHandle<AudioAsset> = AssetHandle::default();
let source = AudioSource::new(audio_handle).with_volume(0.5);
assert_eq!(source.volume, 0.5);

pub fn with_pitch(self, pitch: f32) -> AudioSource

Sets the pitch (0.5-2.0, clamped).

Examples

use goud_engine::ecs::components::AudioSource;
use goud_engine::assets::AssetHandle;
use goud_engine::assets::loaders::audio::AudioAsset;

let audio_handle: AssetHandle<AudioAsset> = AssetHandle::default();
let source = AudioSource::new(audio_handle).with_pitch(1.5);
assert_eq!(source.pitch, 1.5);

pub fn with_looping(self, looping: bool) -> AudioSource

Sets whether the audio should loop.

pub fn with_channel(self, channel: AudioChannel) -> AudioSource

pub fn stop(&mut self)

Stops the audio (resets playback position).

pub fn is_playing(&self) -> bool

Returns whether the audio is currently playing.

pub fn is_spatial(&self) -> bool

Returns whether the audio is spatial.

pub fn has_sink(&self) -> bool
