问题描述

我有一个可以在墙上移动和反弹的 Color Sprite 对象.当我抓住它并在屏幕上触摸它时，如何使它消失?

I have a Color Sprite object which can move and bounce at the wall. How can I make it disappear when I catch it and touch it on the screen?

推荐答案

你必须为你的精灵设置一个名字，比如ballNode"，然后在touchesBegan"函数中处理它.

you have to set a name for your sprite like "ballNode", then in "touchesBegan" function you can handle it.

 override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    for touch in (touches) {
        let positionInScene = touch.location(in: self)
        let touchedNode = self.atPoint(positionInScene)
        if let name = touchedNode.name {
            if name == "ballNode" {
                //make it hidden by touchedNode.isHidden = true
                //or remove it from parent by touchedNode.removeFromParent()
            }
        }
    }
}
