respondToSwipeGesture在很多場景

我想輕掃手勢添加到從主場景繼承場景（GameScene）respondToSwipeGesture在很多場景

extension GameScene { 

    class Scene1: GameScene { 

     override func didMove(to view: SKView) { 

      let swipeRight = UISwipeGestureRecognizer(target: self, action: #selector(self.respondToSwipeGesture)) 
      swipeRight.direction = .right 
      view.addGestureRecognizer(swipeRight) 

      let swipeDown = UISwipeGestureRecognizer(target: self, action: #selector(self.respondToSwipeGesture)) 
      swipeDown.direction = UISwipeGestureRecognizerDirection.down 
      view.addGestureRecognizer(swipeDown) 

      let swipeUp = UISwipeGestureRecognizer(target: self, action: #selector(self.respondToSwipeGesture)) 
      swipeUp.direction = UISwipeGestureRecognizerDirection.up 
      view.addGestureRecognizer(swipeUp) 

      let swipeLeft = UISwipeGestureRecognizer(target: self, action: #selector(self.respondToSwipeGesture)) 
      swipeLeft.direction = UISwipeGestureRecognizerDirection.left 
      view.addGestureRecognizer(swipeLeft) 
     } 
    } 
    class Scene2: GameScene { 

     override func didMove(to view: SKView) { 

      let swipeRight = UISwipeGestureRecognizer(target: self, action: #selector(self.respondToSwipeGesture)) 
      swipeRight.direction = .right 
      view.addGestureRecognizer(swipeRight) 

      let swipeDown = UISwipeGestureRecognizer(target: self, action: #selector(self.respondToSwipeGesture)) 
      swipeDown.direction = UISwipeGestureRecognizerDirection.down 
      view.addGestureRecognizer(swipeDown) 

      let swipeUp = UISwipeGestureRecognizer(target: self, action: #selector(self.respondToSwipeGesture)) 
      swipeUp.direction = UISwipeGestureRecognizerDirection.up 
      view.addGestureRecognizer(swipeUp) 

      let swipeLeft = UISwipeGestureRecognizer(target: self, action: #selector(self.respondToSwipeGesture)) 
      swipeLeft.direction = UISwipeGestureRecognizerDirection.left 
      view.addGestureRecognizer(swipeLeft) 
     } 
    } 
}

而且每次我必須不時在所有重新編寫代碼等及其他場景。也許，還有另一種出路。

是的，如果你看了你的代碼，你會發現你永遠不會爲場景添加一個手勢，而是將它添加到視圖中。現在問自己，你還有什麼其他物體可以訪問視圖？答案是視圖控制器。這是你想要放置你的手勢代碼的地方。

我試過但我做不到。 – Proffan

是什麼？這是沒有意義的 – Knight0fDragon

var scene = GameScene（size：CGSize（width：1024，height：768）） func viewDidLoad（）{ super.viewDidLoad（） let view = self.view as！ SKView let swipeDown = UISwipeGestureRecognizer（target：scene，action：#selector（scene.respondToSwipeGesture（gesture :) :)） swipeDown.direction = .down view.addGestureRecognizer（swipeRight） – Proffan
