如何檢測，如果我拍了拍一個SKShapeNode

Question

覆蓋FUNC didMove（查看：SKView）{

view.scene?.anchorPoint = CGPoint(x: 0,y : 0) 

    castle = SKShapeNode(circleOfRadius: ballRadius1) 
    castle.physicsBody = SKPhysicsBody(circleOfRadius:ballRadius1) 
    castle.fillColor = .white 
    castle.name = "castle" 
    castle.position = CGPoint(x: 0, y: 0) 
    castle.physicsBody?.isDynamic = false 
    castle.physicsBody?.affectedByGravity = false; 
    castle.isUserInteractionEnabled = true 
    self.addChild(castle) 

我在屏幕中間的圓圈，我想讓我輕敲時它消失。你能幫我麼？這是一個SKShapeNode並具有相同的半徑PhysicsBody

你可以使用的touchesBegan，使它看起來像這樣

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


    for touch: AnyObject in touches{ 

     let pointOfTouch = touch.location(in: self) 
     let nodeITapped = atPoint(pointOfTouch) 
     let nameOfTappedNode = nodeITapped.name 

     if nameOfTappedNode == "castle"{ 
      //make it do whatever you want 
      castle.removeFromParent() 

     } 

    } 


} 

，你也可以實現它在touchesEnded，而是如果你希望節點立即消失隨着用戶釋放觸摸。
