# GKSceneRootNodeType

Identifies scene classes from other frameworks that support embedded GameplayKit information.

```
protocol GKSceneRootNodeType : NSObjectProtocol
```

## Overview

You do not define classes that adopt this protocol. GameplayKit adds this protocol declaration to classes (such as <doc://com.apple.documentation/documentation/SpriteKit/SKScene>) for which the [`GKScene`](/documentation/GameplayKit/GKScene) class supports archiving and loading embedded GameplayKit information.

For more information, see [GameplayKit Programming Guide](https://developer.apple.com/library/archive/documentation/General/Conceptual/GameplayKit_Guide/index.html#//apple_ref/doc/uid/TP40015172).
