Playback instance for [AudioStreamPolyphonic]. After setting the [code]stream[/code] property of [AudioStreamPlayer], [AudioStreamPlayer2D], or [AudioStreamPlayer3D], the playback instance can be obtained by calling [method AudioStreamPlayer.get_stream_playback], [method AudioStreamPlayer2D.get_stream_playback] or [method AudioStreamPlayer3D.get_stream_playback] methods.

|
Play an [AudioStream] at a given offset, volume and pitch scale. Playback starts immediately.
|
|
The return value is a unique integer ID that is associated to this playback stream and which can be used to control it.
|
|
This ID becomes invalid when the stream ends (if it does not loop), when the [AudioStreamPlaybackPolyphonic] is stopped, or when [method stop_stream] is called.
|
|
This function returns [constant INVALID_ID] if the amount of streams currently playing equals [member AudioStreamPolyphonic.polyphony]. If you need a higher amount of maximum polyphony, raise this value.
