缓慢Skscene转换

Question

我有两个场景：家庭和游戏。与过渡到主场景相比，过渡到场景真的很慢。我认为这是因为我的比赛场面更多。有什么方法可以预先加载场景吗？或者让过渡更加无缝？

我对这个论坛的答案感兴趣Preload a Scene to prevent lag? 但我不知道从哪里开始。我在哪里放置部分和B部分的答案

这里是我使用

override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) { 
    let touch = touches 
    let location = touch.first!.locationInNode(self) 
    let node = self.nodeAtPoint(location) 

    if (node.name == "Balloon") { 

     let sceneAction = SKAction.runBlock({ 
      let secondScene = Scene2(size: self.size) 
      let transition = SKTransition.fadeWithDuration(1) 
      secondScene.scaleMode = SKSceneScaleMode.AspectFill 
      self.scene!.view?.presentScene(secondScene, transition: transition) 
     }) 
      PlayButton.runAction(SKAction.sequence([sound,SKAction.animateWithTextures(array, timePerFrame: 0.1),sceneAction,SKAction.waitForDuration(1)])) 


    }  

什么任何其他解决办法是罚款。

感谢

我做这做工作： 在didView HomeScene放preloadGameScene() 而且总是在家里的一幕：

fileprivate var nextScene: SKScene? 

func preloadGameScene() { 
    let qualityOfServiceClass = QOS_CLASS_BACKGROUND 
    let backgroundQueue = dispatch_get_global_queue(qualityOfServiceClass, 0) 
    dispatch_async(backgroundQueue, { 
     self.nextScene = GameScene(fileNamed:"yoursksfilename") 
     dispatch_async(dispatch_get_main_queue(), {() -> Void in 
      print("SCENE LOADED") 
      let loading = self.childNodeWithName("Loading") as? SKLabelNode 
      self.playButton?.hidden = false 
      self.playButton?.alpha = 0 
      //loading?.hidden = true 
      self.playButton?.runAction(SKAction.fadeAlphaTo(1.0, duration: 0.4)) 
      loading!.runAction(SKAction.fadeAlphaTo(0.0, duration: 0.4)) 
     }) 

    }) 
} 

goToGameScene()通过按钮个人SKButton类叫做：

func goToGameScene() { 
     guard let nextScene = nextScene else {return} 
     let transition = SKTransition.crossFadeWithDuration(0.5) 
     nextScene.scaleMode = .AspectFill 
     scene!.view?.presentScene(nextScene, transition: transition) 
    }

UPDATE SWIFT 3

fileprivate var nextScene: SKScene? 

func preloadGameScene() { 
     let qualityOfServiceClass = DispatchQoS.QoSClass.background 
     let backgroundQueue = DispatchQueue.global(qos: qualityOfServiceClass) 
     backgroundQueue.async(execute: { 
      self.nextScene = GameScene(fileNamed:"yoursksfilename") 
      DispatchQueue.main.async(execute: {() -> Void in 
       print("SCENE LOADED") 
       let loading = self.childNode(withName: "Loading") as? SKLabelNode 
       self.playButton?.isHidden = false 
       self.playButton?.alpha = 0 
       //loading?.hidden = true 
       self.playButton?.run(SKAction.fadeAlpha(to: 1.0, duration: 0.4)) 
       loading?.run(SKAction.fadeAlpha(to: 0.0, duration: 0.4)) 
      }) 

     }) 
    }
