Swift 通过按钮触摸移动SKSpriteNode

在我的游戏场景中我得到了英雄的斯普林泰诺德。我实现了两个按钮（向上和向下）。我需要我的英雄的斯普林泰诺德通过按键上下移动。但我只看到触控移动和触控移动的方法。我需要一些关于touchsbegind（在我点击按钮时感觉到按钮在点击）的信息。

您创建某种重复步骤，从

touchsbegind

开始，到

touchseded

结束，或者当触摸移出节点时 通过检查

touchesMoved

override func touchesBegan(...)
{
   ...
   let moveAction = SKAction.repeatForever(SKAction.move(by:CGPoint(x:x,y:y)))
   node.run(moveAction,forKey:"moving")
   ...
}
override func touchesMoved(...)
{
   ...
   //add a check to see if if touch.position is not inside the button
   if (...)
   {
       node.removeAction(withKey:"moving")
   } 
   ...
}
override func touchesEnded(...)
{
   ...
   node.removeAction(withKey:"moving")
   ...
}
override func touchesCancelled(...)
{
   ...
   node.removeAction(withKey:"moving")
   ...
}

、在

触摸取消

或将触摸移出节点时结束 通过检查

touchesMoved

override func touchesBegan(...)

   let moveAction = SKAction.repeatForever(SKAction.move(by:CGPoint(x:x,y:y)))
