Question

嘿伙计们我正在iphone上测试我的游戏，我意识到我的暂停按钮有问题。为什么？因为当我回到游戏时暂停游戏并寻找另一个应用程序时，它不会触摸恢复按钮。这是代码：

 class GameScene: SKScene, SKPhysicsContactDelegate{

 var PauseButton = SKSpriteNode(imageNamed: "pause")

 var Resume = SKSpriteNode(imageNamed: "resume1")
}


 init(size: CGSize, won: Bool) {
    super.init(size: size)      
  //pause

    PauseButton.position = CGPointMake(330, 700)
    PauseButton.zPosition = 3;
    PauseButton.size = CGSizeMake(40, 40);
    PauseButton.name = "PauseButton"

    self.addChild(PauseButton)

   //resume 
    Resume = SKSpriteNode(imageNamed: "resume1")
    Resume.position = CGPointMake(520, 450)
    Resume.zPosition = 100
    Resume.setScale(1.3)   

    }

 override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
    /* Called when a touch begins */

    show = self.scene as SKScene!


    for touch in touches  {


        let Location:CGPoint = touch.locationInNode(self)
        let Node:SKNode = self.nodeAtPoint(Location)



        if(Node == PauseButton){


            self.show.paused = true

            PauseButton.removeFromParent()

            self.addChild(Resume)

        }

        if(Node == Resume){


            Resume.removeFromParent()
            self.show.paused = false

            self.addChild(PauseButton)
        }

有任何帮助吗？感谢

当你回到你的应用程序时，SpriteKit会自动恢复。所以你需要：

第1步：创建一个变量：

var wasPaused : Bool = false

第2步：在暂停/恢复功能中更改它：

wasPaused = true // pause func
wasPaused = false // resume fun

第3步：更新你的场景：

override func update(currentTime: CFTimeInterval) {
    if isPausing{
        self.paused = true
        return
    }
}

暂停视图而不是场景。

override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
    guard let view = view else {
        return
    }

    view.paused = !view.paused
}

暂停和恢复SKScene
