As the error describes, the GKState class doesn't have any member functions called childNodeWithName.

You forget to reference GameScene file

Replace:

Ninja_Run = self.childNodeWithName("Ninja_Run") as! SKSpriteNode

With:

let scene = GameScene(fileNamed:"GameScene") //Or everywhere is your sprite
Ninja_Run = scene.childNodeWithName("Ninja_Run") as! SKSpriteNode
