TouchesBeganが機能しない

Question

最後のラベルlblTryAgain GameSceneという名前の別のクラスに戻りたいが、タップアクションがtouchesBegan関数に入っていない。 私はちょうど誰かがチュートリアルに従うか、コード全体がhttps://www.raywenderlich.com/87231/make-game-like-mega-jump-sprite-kit-swift-part-1

import SpriteKit 

class EndGameScene: SKScene { 

    required init?(coder aDecoder: NSCoder) { 
     super.init(coder: aDecoder) 
    } 

    override init(size: CGSize) { 
     super.init(size: size) 

     // Stars 
     let star = SKSpriteNode(imageNamed: "Star") 
     star.position = CGPoint(x: 25, y: self.size.height-30) 
     addChild(star) 

     let lblStars = SKLabelNode(fontNamed: "ChalkboardSE-Bold") 
     lblStars.fontSize = 30 
     lblStars.fontColor = SKColor.white 
     lblStars.position = CGPoint(x: 50, y: self.size.height-40) 
     lblStars.horizontalAlignmentMode = SKLabelHorizontalAlignmentMode.left 
     lblStars.text = String(format: "X %d", GameState.sharedInstance.stars) 
     addChild(lblStars) 

     // Score 
     let lblScore = SKLabelNode(fontNamed: "ChalkboardSE-Bold") 
     lblScore.fontSize = 60 
     lblScore.fontColor = SKColor.white 
     lblScore.position = CGPoint(x: self.size.width/2, y: 300) 
     lblScore.horizontalAlignmentMode = SKLabelHorizontalAlignmentMode.center 
     lblScore.text = String(format: "%d", GameState.sharedInstance.score) 
     addChild(lblScore) 

     // High Score 
     let lblHighScore = SKLabelNode(fontNamed: "ChalkboardSE-Bold") 
     lblHighScore.fontSize = 30 
     lblHighScore.fontColor = SKColor.cyan 
     lblHighScore.position = CGPoint(x: self.size.width/2, y: 150) 
     lblHighScore.horizontalAlignmentMode = SKLabelHorizontalAlignmentMode.center 
     lblHighScore.text = String(format: "High Score: %d", GameState.sharedInstance.highScore) 
     addChild(lblHighScore) 


     // Try again 
     let lblTryAgain = SKLabelNode(fontNamed: "ChalkboardSE-Bold") 
     lblTryAgain.fontSize = 30 
     lblTryAgain.fontColor = SKColor.white 
     lblTryAgain.position = CGPoint(x: self.size.width/2, y: 50) 
     lblTryAgain.horizontalAlignmentMode = SKLabelHorizontalAlignmentMode.center 
     lblTryAgain.text = "Tap To Try Again" 
     lblTryAgain.isUserInteractionEnabled = true 
     addChild(lblTryAgain) 


    } 

    func touchesBegan(touches: NSSet, withEvent event: UIEvent) { 
     // Transition back to the Game 
     let reveal = SKTransition.fade(withDuration: 0.5) 
     let gameScene = GameScene(size: self.size) 
     self.view!.presentScene(gameScene, transition: reveal) 
    } 

} 

Answer 1

touchesBeganで利用可能で見たい場合はSpriteKitベースでゲームを作成する方法を学ぶためのチュートリアルを、以下の午前にのみself.viewで動作し、それオーバーライドfuncですisUserInteractionEnabledがチェックされ、print文が動作しない場合がありますことを確認してください。この

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) { 

    print("working") 
} 

Answer 2

を試みる他のUI では動作しません。 sceneDidLoadと印刷isUserInteractionEnabled
