Question

我在按下按钮时尝试切换场景，但是，当我点击它时，没有任何反应，也没有任何内容被打印出来。没有错误，我只是想知道它为什么不起作用。我编程的节点显示在正确的大小和位置，但当你点击它时，没有任何东西通过。谢谢你的帮助。

代码：

class LevelScene: SKScene, SKPhysicsContactDelegate {

    var isFingerOnBlock = false
 let LevelOneName = "levelOne"

    override func didMove(to view: SKView) {
        super.didMove(to: view)
        let Pineapple = SKSpriteNode(imageNamed: "ball")
        Pineapple.isUserInteractionEnabled = true
        Pineapple.position = CGPoint(x: self.frame.midX - 200, y: self.frame.midY);
        Pineapple.name = "pineapple"
        addChild(Pineapple)

    }





   func touchesBegan(touches: NSSet, withEvent event: UIEvent)
    {
               let touch = touches.anyObject() as! UITouch
        let location = touch.location(in: self)
        let nodes = self.nodes(at: location)

        for node in nodes
        {
            if node.name == "pineapple"
            {
           print("ceeds")

                if let scene = GameScene(fileNamed:"GameScene") {
                    // Configure the view.
                    let skView = self.view!
                    skView.showsFPS = true
                    skView.showsNodeCount = true

                    /* Sprite Kit applies additional optimizations to improve rendering performance */
                    skView.ignoresSiblingOrder = true

                    /* Set the scale mode to scale to fit the window */
                    scene.scaleMode = .aspectFit

                    skView.presentScene(scene)


                }
                break
            }
        }
}

}

您已宣布

func touchesBegan(touches: NSSet, withEvent event: UIEvent)

该签名没有内置功能，你从不调用该功能;因此你的函数从不调用。

谢谢马特！我修复了我的代码：它现在有效..

 override func touchesBegan(_ touches: Set<UITouch>,
                      with event: UIEvent?)    {
         let touch = touches.first!
        let location = touch.location(in: self)
        let node : SKNode = self.atPoint(location)
        if(atPoint(location) == node){
            if node.name == "levelOne" {
                if let scene = GameScene(fileNamed:"GameScene") {
                    // Configure the view.
                    let skView = self.view as! SKView
                    skView.showsFPS = true
                    skView.showsNodeCount = true

                    /* Sprite Kit applies additional optimizations to improve rendering performance */
                    skView.ignoresSiblingOrder = true

                    /* Set the scale mode to scale to fit the window */
                    scene.scaleMode = .aspectFit

                    skView.presentScene(scene)


                }
            }

        }

}
