Question

我有两个场景：家庭和游戏。与过渡到家庭场景相比，过渡到场景的速度非常慢。我想这是因为在我的比赛场景中有更多的讨价还价。有什么方法可以预先加载游戏场景吗？或者让过渡更加无缝？

我对此论坛中的答案感兴趣Preload a Scene to prevent lag? 但我不知道从哪里开始。我在哪里放置答案的A部分和B部分

这是我正在使用的

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)]))


    }

任何其他解决方案都可以。

我这样做并且有效：在 HomeScene 的 didView 中放置preloadGameScene() 并且总是在家庭场景中：

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()由按钮个人SKButton类调用：

    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))
            })

        })
    }
