更改默认 SKScene

Changing default SKScene

我有一个名为 IntroLayer 的 class 我正在尝试在启动游戏时加载为初始场景。但是,按照这些简单步骤中的描述,简单地将 GameScene 更改为 IntroScene 后,我的 IntroScene 没有被加载。我在 if let 场景上设置断点以查看它是否跳过它,甚至在实际的 IntroScene 中设置断点以验证未调用 didMoveToView。有什么想法吗?

我在 GameViewController 中将 let 场景从 GameScene 更改为 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 class 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,当我启动该应用程序时,似乎在我设置断点时甚至没有调用 IntroScene,而且我的屏幕背景为灰色。

您需要将 GameScene.sks 重命名为 IntroScene.sks

sks文件是场景数据的存档文件,如果你打开它,你会发现你可以改变场景的很多东西,甚至可以直接添加节点和精灵。当您调用 if let scene = IntroScene(fileNamed:"IntroScene") { 时,您正在解压缩 sks 文件以作为场景加载,因此无论何时您想要创建新场景,请记住您将需要此文件。
