我需要的一切都在下面评论，我有一个功能，当我点击它时，游戏应该重新启动。重启功能可以自行运行，但我只希望它在用户点击屏幕后重启。如果您需要澄清代码的某些部分的作用，请在下面发表评论，请告诉我我做错了什么，谢谢!

最佳答案

据我了解，SKScene符合 UIResponder协议(protocol)，因为你正在使用 touchesBegan和 touchesMoved方法。该协议(protocol)还具有 touchesEnded(Set<UITouch>, with: UIEvent?)方法。 基本上你需要添加如下内容:

override func touchesEnded(Set<UITouch>, with: UIEvent?)
{
    let skView = self.view!
    skView.presentScene(scene)
}

当用户在点击 GameScene 后将手指从屏幕上移开时，将调用此方法目的。

您可以使用 UITapGestureRecognizer以及。然而，要这样做，您需要创建它的一个实例，将您的类声明为它的委托(delegate)，将您想要利用的 View 添加到它的集合中并为其附加一个方法。我从未以编程方式完成此操作，仅在 IB 中进行过。设置如下所示:

通过代码添加点击手势:

在你的 GameScene 类中:

weak var tapGesture : UITapGestureRecognizer!
override func didMoveToView(view: SKView) {
    tapGesture  = UITapGestureRecognizer(target:self,action:#selector(self.handleTap:)
    view.addGestureRecognizer(tapGesture )
}
func handleTap(sender:UITapGestureRecognizer){
    //restartLogic here
}
deinit{
    view.removeGestureRecognizer(tapGesture)
}
