How to call method from ViewController in GameScene

Question

I have a method that has a custom segue in my viewController that looks like this:

func gameOver() {
    performSegueWithIdentifier(\"GameOver\", sender: nil         


        

Answer 1

I have done by create protocol, I have 3 game scene (GameScene, GamePlayScene, GameEndScene) and one game controller (GameViewController)

first create gameProtocol

protocol GameDelegate {
 func gameOver()
}

implement protocol in GameViewController

class GameViewController: UIViewController, GameDelegate {
override func viewDidLoad() {
 super.viewDidLoad()
 let scene = GameScene(size: skView.bounds.size)
        scene.scaleMode = .AspectFill
        scene.delegate = self
 }

 // MARK: Game Delegate
 func gameOver() {
    self.performSegueWithIdentifier("yoursegue", sender: self)
 }
}

put delegate property in GameScene class

class GameScene: SKScene {
 var delegate: GameDelegate?

 // call GamePlayScene and put delegate property
 func redirectToPlay() {
        let transition = SKTransition.pushWithDirection(SKTransitionDirection.Left, duration: 1.0)
        let menuScene = GamePlayScene(size: size)
         menuScene.delegate = self.delegate
        self.view?.presentScene(menuScene, transition: transition)
   }
}

and put protocol in GamePlayScene too

class GamePlayScene: SKScene {
     var delegate: GameDelegate?

     // call GameEndScene and put delegate property
     func gameScore() {
            let transition = SKTransition.pushWithDirection(SKTransitionDirection.Left, duration: 1.0)
            let menuScene = GameEndScene(size: size)
             menuScene.delegate = self.delegate
            self.view?.presentScene(menuScene, transition: transition)
       }
    }

and last, put delegate property and call gameOver function

class GameEndScene: SKScene {
     var delegate: GameDelegate?

     init(size: CGSize) {
      // call gameOver function
      self.delegate?.gameOver()
     }
   }

Hope that work and can help you
