Instance Property


The AVFoundation audio engine used to play audio from audio nodes contained in the scene.


@property(nonatomic, retain, readonly) AVAudioEngine *audioEngine;


An audio engine instance is automatically created for you when the scene is created. You can use methods and properties on a scene’s audio engine for overall control of all of its child audio nodes. The following code shows how a scene’s overall volume can be reduced from its default of 1.0 down to 0.2 and then paused:

let scene = SKScene()
scene.audioEngine.mainMixerNode.outputVolume = 0.2
