AudioListener class Audio

Places the ears of the nearest ancestor AudioEngine on a node.

The listener pose follows the owning node's world transform, with the node's local +Z as the facing direction and +Y as up (the camera convention, so a listener on the camera node hears what the camera sees). Velocity for doppler is derived automatically.

Optional. With no listener mounted the engine follows the scene's primary camera. When several are mounted, the first mounted wins.

engine → AudioEngine?
The engine this listener registered with, while mounted.

hashCode → int
The hash code for this object.

isAttached → bool
Whether this component is currently attached to a node.

isLoaded → bool
Whether onLoad has completed.

Methods

cloneFor(Node cloneOwner) → Component?
Returns a copy of this component for cloneOwner, the Node.clone counterpart of the owning node, or null to not carry the component to clones (the default).
inherited
fixedUpdate(double fixedDt) → void
Called once per fixed physics step while the component is mounted, enabled, and loaded. fixedDt is the fixed timestep of the surrounding PhysicsWorld, not the frame interval.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
onAttach() → void
Called when this component is added to a node.
inherited
onDetach() → void
Called when this component is removed from a node.
inherited
onLoad() → Future<void>
Optional asynchronous setup, such as loading an asset.
inherited
onMount() → void
Called when the owning node enters a live scene graph.
override
onUnmount() → void
Called when the owning node leaves a live scene graph.
override
toString() → String
A string representation of this object.
inherited
update(double deltaSeconds) → void
Called once per frame while the component is mounted, enabled, and loaded. deltaSeconds is the elapsed time since the previous tick.

Operators

operator ==(Object other) → bool
The equality operator.
