# isPlaying

A Boolean value that determines whether the scene is playing.

## Declaration

```swift
var isPlaying: Bool { get set }
```

## Discussion

Discussion If the value of this property is false (the default), SceneKit does not increment the scene time, so animations associated with the scene do not play. Change this property’s value to true to start animating the scene.
