ios - 如何使用滑动手势移动 Sprite ？

                                            <p><p>如何通过向左滑动将 Sprite 移动到左侧，通过向右滑动将 Sprite 向右移动等等？ </p>

<p>如果我向左滑动，我的 Sprite 会向左移动 20 点。我正在使用 SpriteKit 和 Swift。</p></p>

                                            <p><p>谢谢! @jonogilmour</p>

<p>我是这样解决的:</p>

<pre><code>let right = SKAction.moveByX(64, y: 0, duration: 0.6)
    let left = SKAction.moveByX(-64, y: 0, duration: 0.6)
    let up = SKAction.moveByX(0, y: 64, duration: 0.6)
    let down = SKAction.moveByX(0, y: -64, duration: 0.6)



    func swipedRight(sender:UISwipeGestureRecognizer){
      player.runAction(right)
    }
    func swipedLeft(sender:UISwipeGestureRecognizer){
      player.runAction(left)
    }
    func swipedUp(sender:UISwipeGestureRecognizer){
      player.runAction(up)
    }
    func swipedDown(sender:UISwipeGestureRecognizer){
      player.runAction(down)
    }


override func didMoveToView(view: SKView) {


      let swipeRight:UISwipeGestureRecognizer = UISwipeGestureRecognizer(target: self, action: Selector(&#34;swipedRight:&#34;))
    swipeRight.direction = .Right
    view.addGestureRecognizer(swipeRight)

    let swipeLeft:UISwipeGestureRecognizer = UISwipeGestureRecognizer(target: self, action: Selector(&#34;swipedLeft:&#34;))
    swipeLeft.direction = .Left
    view.addGestureRecognizer(swipeLeft)

    let swipeUp:UISwipeGestureRecognizer = UISwipeGestureRecognizer(target: self, action: Selector(&#34;swipedUp:&#34;))
    swipeUp.direction = .Up
    view.addGestureRecognizer(swipeUp)

    let swipeDown:UISwipeGestureRecognizer = UISwipeGestureRecognizer(target: self, action: Selector(&#34;swipedDown:&#34;))
    swipeDown.direction = .Down
    view.addGestureRecognizer(swipeDown)
............
