swift - 通过触摸按钮移动 SKSpriteNode

Question

我的 GameScene 中有 hero 的 SKSpriteNode。我实现了两个按钮(向上和向下)。我需要我的英雄的 SKSpriteNode 通过触摸按钮上下移动。但我只看到 touchesMoved 和 touchesEnded 方法。我需要一些关于 touchesBegan 的东西(当我点击它时感觉按钮被点击)。

Answer 1

您创建某种重复步骤，从 touchesBegan 开始到 touchesEnded、touchesCancelled 或当触摸离开节点通过检查 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")
   ...
}
