Module audio 

Sound: the AudioSource component and the AudioBus that scripts talk to.

The engine itself plays nothing. Scripts and components only queue requests on the scene’s bus; a shell (the editor or the player) hands them to the kvas_audio backend once per frame. That keeps the simulation deterministic and testable without a sound card.

use kvas_engine::audio::AudioBus;
let mut bus = AudioBus::default();
let id = bus.play("sounds/click.wav", 0.8);
bus.stop(id);
assert_eq!(bus.drain().len(), 2);

Structs

AudioBus

Pending audio requests and the master volume. Lives in the scene, is never saved.

AudioSource

SoundId

Handle of a sound started through the bus; use it to stop or adjust that sound later.

Enums

AudioCmd

One queued request for the audio backend.

Functions

cone_gain

Gain of a directional source: full inside the inner 60 % of the cone, fading to 10 % at its edge and beyond. forward is where the source points, to_listener the direction from the source to the listener.

distance_gain

Gain for a 3D sound: 1 inside min, falling linearly to 0 at max.

stereo_pan

Stereo position (-1 left .. 1 right) of a source seen from a listener.
