Overrides the location sounds are heard from. Once added to the scene tree and enabled using [method make_current], this node will override the location sounds are heard from. This can be used to listen from a location different from the [Camera3D]. [b]Note:[/b] There is no 2D equivalent for this node yet. Disables the listener to use the current camera's listener instead. Returns the listener's global orthonormalized [Transform3D]. Returns [code]true[/code] if the listener was made current using [method make_current], [code]false[/code] otherwise. [b]Note:[/b] There may be more than one Listener3D marked as "current" in the scene tree, but only the one that was made current last will be used. Enables the listener. This will override the current camera's listener.
