如何使形状不去GameOver？ -SpriteKit

Question

我正在创建一个游戏，其中有一个正方形，每次玩家点击正方形时，它都会进入 GameOver 场景。我想要做的就是当点击正方形时，它将被分配到屏幕的不同位置以在正方形上点击。

这是我的代码：

    let touch:UITouch = touches.first!
    let positionInScene = touch.location(in: self)
    let touchedNode = self.atPoint(positionInScene)




   if let name = touchedNode.name
    {
        //The first ball that shows up
        if name == "startball"
        {
            print("Touched", terminator: "")
             addBall(ballSize)




            self.addChild(score)
        }
        else if name == "shape"{

            scoreCount += 1

           addBall(ballSize)




            audioPlayer.play()

        }  





    }



    else {

        let scene =  GameOver(size: self.size)
        scene.setMyScore(0)
        let skView = self.view! as SKView
        skView.ignoresSiblingOrder = true
        scene.scaleMode = .resizeFill
        scene.size = skView.bounds.size
        scene.setMessage("You Lost!")

        scene.setEndGameMode(va)
        gameTimer.invalidate()
        shownTimer.invalidate()
        print(" timers invalidated ", terminator: "")
        ran = true
        skView.presentScene(scene, transition: SKTransition.crossFade(withDuration: 0.25))
    }








    if firstTouch {
        shownTimer = Timer.scheduledTimer(timeInterval: 1, target: self, selector: #selector(GameScene.decTimer), userInfo: nil, repeats: true)
        gameTimer = Timer.scheduledTimer(timeInterval: TIME_INCREMENT, target:self, selector: Selector("endGame"), userInfo: nil, repeats: false)
        firstTouch = false



    }

    if touchCount > 5 {

        for touch: AnyObject in touches {
            let skView = self.view! as SKView
            skView.ignoresSiblingOrder = true
            var scene: Congratz!
            scene =  Congratz(size: skView.bounds.size)
            scene.scaleMode = .aspectFill
            skView.presentScene(scene, transition: SKTransition.doorsOpenHorizontal(withDuration: 1.0))



        }




    }
    touchCount += 1



}




    override func update(_ currentTime: TimeInterval) {
    super.update(currentTime)




}

func endGame(){
    shownTimer.invalidate()
    gameTimer.invalidate()
    let scene =  GameOver(size: self.size)
    scene.setMyScore(scoreCount)
    if let skView = self.view {
        skView.ignoresSiblingOrder = false
        scene.scaleMode = .resizeFill
        scene.size = skView.bounds.size
        scene.setMessage("Times up")

        skView.presentScene(scene, transition: SKTransition.crossFade(withDuration: 0.25))
    }

}







       override func addBall(_ size: Int) {
      // Add the ball
      let currentBall = SKShapeNode(circleOfRadius: CGFloat(size))

    let viewMidX = view!.bounds.midX
    let viewMidY = view!.bounds.midY

    currentBall.fillColor = pickColor()



    currentBall.position = randomBallPosition()




    if scoreCount != 0{
        if scoreCount == 1{
            self.addChild(score)
            self.addChild(timeLeftLabel)
            self.childNode(withName: "welcome")?.removeFromParent()
        }
        self.childNode(withName: "ball")?.run(getSmaller)
        self.childNode(withName: "ball")?.removeFromParent()

    }
     currentBall.name = "ball"


    self.addChild(currentBall)
}

     func addSquare(_ size: Int) {
    // Add the square
    let shape = SKShapeNode(rectOf: CGSize(width:CGFloat(size), height:CGFloat(size)))

    shape.path = UIBezierPath(roundedRect: CGRect(x: 64, y: 64, width: 160, height: 160), cornerRadius: 50).cgPath

    shape.fillColor = pickColor()

    shape.position = randomBallPosition()

    shape.name = "shape"

    self.addChild(shape)

} 


    func randomBallPosition() -> CGPoint {
    let xPosition = CGFloat(arc4random_uniform(UInt32((view?.bounds.maxX)! + 1)))
    let yPosition = CGFloat(arc4random_uniform(UInt32((view?.bounds.maxY)! + 1)))


    return CGPoint(x: xPosition, y: yPosition)

}

我的建议是为不同的形状制作类似enum 的东西，这样您就可以跟踪您正在使用的形状。

enum GameShape: Int {

    case circle = 0
    case square = 1

}

然后在GameScene 的顶部创建一个GameShape 属性：

var currentShape: GameShape = .circle

然后您可以创建某种updateShape 方法，您可以在您的touchesBegan 方法中调用它，而不仅仅是addBall

func updateShape(shapeSize: CGSize) {

    switch currentShape {
        case .circle:
            addCircle(shapeSize)
        case .square:
            addSquare(shapeSize)
        default:
            break
    }

    // However you want to setup the condition for changing shape
    if (condition) {
        currentShape = .square
    }

}

func addBall(_ size: CGSize) {
    // Add the ball
}

func addSquare(_ size: CGSize) {
   // Add the square
}

现在在您的touchesBegan 方法中，您可以调用updateShape，而不是调用addBall(size：

override func touchesBegan(_ touches: Set<UITouch>!, with event: UIEvent?) {

    // Setup your code for detecting position for shape origin
    updateShape(shapeSize)

}

EDIT - 你的代码一团糟。你真的应该花时间确保在提交时它的格式正确，否则真的很难帮助你。缩进有助于查看闭包的开始和结束位置。据我所知，您的 addBall 方法中似乎嵌套了两个或多个函数。不是很好。我已经尽力为你清理了。您仍然需要编写代码来使形状变成正方形，但我已经引导您朝着正确的方向开始实现这一目标：

func addBall(_ size: CGSize) {
    // Add the ball
    let currentBall = SKShapeNode(circleOfRadius: CGFloat(size))

    let viewMidX = view!.bounds.midX
    let viewMidY = view!.bounds.midY

    currentBall.fillColor = pickColor()

    shape.path = UIBezierPath(roundedRect: CGRect(x: 64, y: 64, width: 160, height: 160), cornerRadius: 50).cgPath

    shape.fillColor = pickColor()

    currentBall.position = randomBallPosition()
    shape.position = randomBallPosition()

    self.addChild(shape)

    if scoreCount != 0{
        if scoreCount == 1{
            self.addChild(score)
            self.addChild(timeLeftLabel)
            self.childNode(withName: "welcome")?.removeFromParent()
        }
        self.childNode(withName: "ball")?.run(getSmaller)
        self.childNode(withName: "ball")?.removeFromParent()

    }
    currentBall.name = "ball"
    shape.name = "ball"

    self.addChild(currentBall)
}

func addSquare(_ size: CGSize) {
    // Add the square
}

func randomBallPosition() -> CGPoint {
    let xPosition = CGFloat(arc4random_uniform(UInt32((view?.bounds.maxX)! + 1)))
    let yPosition = CGFloat(arc4random_uniform(UInt32((view?.bounds.maxY)! + 1)))


    return CGPoint(x: xPosition, y: yPosition)

}

现在上面的代码假设您有一些名为 shape 的属性，因为据我所知，您从未明确实例化过它，但您开始对其进行操作。
