Struct SpatialAudioSystem 

pub struct SpatialAudioSystem {
    pub listener_pos: Vec2,
    pub arena_half_width: f32,
    pub distance_model: DistanceModel,
    pub reverb: SpatialReverb,
    pub room_type: RoomType,
    /* private fields */
}

Manages spatial audio: positioned sounds, distance attenuation, and reverb.

Fields

listener_pos: Vec2

Listener position (usually camera/player center).

arena_half_width: f32

Arena half-width for pan calculation.

distance_model: DistanceModel

Distance model.

reverb: SpatialReverb

Room reverb.

room_type: RoomType

Current room type.

Implementations

impl SpatialAudioSystem

pub fn new() -> Self

pub fn set_listener(&mut self, pos: Vec2)

Set the listener position (usually the camera center or player position).

pub fn set_room(&mut self, room: RoomType)

Change the room reverb preset.

pub fn play( &mut self, name: &str, origin: SoundOrigin, volume: f32, lifetime: f32, ) -> u32

Spawn a positioned sound and return its ID.

pub fn update_travel(&mut self, id: u32, from: Vec2, to: Vec2, progress: f32)

Update a traveling sound’s progress.

pub fn stop(&mut self, id: u32)

Stop a sound by ID.

pub fn tick(&mut self, dt: f32)

Tick: update lifetimes, remove expired sounds.

pub fn spatialize( &mut self, sample: f32, origin: SoundOrigin, volume: f32, ) -> (f32, f32)

Compute the spatial mix for a mono sample at a given origin. Returns (left_sample, right_sample) with pan, attenuation, and reverb.

pub fn compute_pan_gain(&self, source_pos: Vec2) -> (StereoPan, f32)

Compute pan and gain for a world position (for external use).

pub fn active_count(&self) -> usize

Number of active sounds.

pub fn clear(&mut self)

Clear all sounds (room transition).
