更改默认SKScene

Question

我有一个名为IntroLayer的类，当我的游戏启动时，我正尝试将其作为初始场景加载。但是，按照这些简单步骤中的描述，简单地将GameScene更改为IntroScene之后，不会加载我的IntroScene。我在if场景上设置了断点，以确保它跳过它，甚至在实际的IntroScene中设置断点来验证didMoveToView没有被调用。有什么想法吗？

I将GameViewController中的let场景从GameScene改为IntroScene，如下所示：

import UIKit
import SpriteKit

class GameViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        if let scene = IntroScene(fileNamed:"IntroScene") {
            // 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 = .AspectFill

            skView.presentScene(scene)
        }
    }

    override func shouldAutorotate() -> Bool {
        return true
    }

    override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {
        if UIDevice.currentDevice().userInterfaceIdiom == .Phone {
            return .AllButUpsideDown
        } else {
            return .All
        }
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Release any cached data, images, etc that aren't in use.
    }

    override func prefersStatusBarHidden() -> Bool {
        return true
    }
}

然后将GameScene.swift重命名为IntroScene.swift，并将类更改为：

import SpriteKit

class IntroScene: SKScene {
    override func didMoveToView(view: SKView) {

        backgroundColor = UIColor.blackColor()


        let fadeIn:SKAction = SKAction.fadeInWithDuration(1.0)
        let fadeOut:SKAction = SKAction.fadeOutWithDuration(1.0)




        let inspiredText = SKLabelNode(fontNamed: "Dead Kansas")
        inspiredText.alpha = 0.0
        inspiredText.text = "Inspired By"
        inspiredText.position = CGPoint(x:CGRectGetMidX(self.frame), y:CGRectGetMidY(self.frame))
        addChild(inspiredText)



        inspiredText.runAction(fadeIn)

    }

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

        for touch in touches {
//            let location = touch.locationInNode(self)


        }
    }

}

然而，当我启动应用程序时，在设置断点时甚至没有调用IntroScene，而且我得到的屏幕有灰色背景。

您需要将您的GameScene.sks重命名为IntroScene.sks

sks文件是您的场景数据的存档文件，如果您打开它，您会注意到您可以更改有关场景的许多内容，甚至可以直接向其添加节点和精灵。当您调用if let scene = IntroScene(fileNamed:"IntroScene") {时，您要将sks文件解压缩为一个场景，因此，每当您想要创建一个新场景时，请记住您将需要这个文件。
