如何在xcode中使用swift创建spritekit游戏的主菜单？

Question

我使用spritekit和swift在xcode中创建了一个非常简单的游戏。我已经完成了实际游戏本身的编码。现在我想创建一个主菜单，当游戏打开时，会出现一个带按钮的菜单，可以进入设置或启动游戏。我不知道我该如何做到这一点。我应该使用故事板吗？如果是这样，我怎么能在xcode中实现它。谢谢大家:)

创建两个新文件。一个精灵套件场景和一个可可触摸文件。将它们命名为相同，例如MenuScene。要创建文件，请单击xcode项目边栏中的文件夹。然后在运行应用程序时使MenuScene显示进GameViewController文件。在viewDidLoad下有一行。 if let scene = GameScene.unarchiveFromFile("GameScene") as? GameScene {在MenuScene变成if let scene = MenuScene.unarchiveFromFile("MenuScene") as? Menu Scene {这点，你必须有一个按钮，引导你到你的GameScene

import SpriteKit 

class MenuScene: SKScene { 

var playButton = SKSpriteNode() 
let playButtonTex = SKTexture(imageNamed: "play") 

override func didMoveToView(view: SKView) { 

    playButton = SKSpriteNode(texture: playButtonTex) 
    playButton.position = CGPointMake(frame.MidX, frame.midY) 
    self.addChild(playButton) 


override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) { 


    if let touch = touches.first as? UITouch { 
     let pos = touch.locationInNode(self) 
     let node = self.nodeAtPoint(pos) 

     if node == playButton { 
      if let view = view { 
       let scene = GameScene.unarchiveFromFile("GameScene") as! GameScene 
       scene.scaleMode = SKSceneScaleMode.AspectFill 
       view.presentScene(scene) 
      } 
     } 
    }  
} 

询问您是否需要进一步的解释。

import SpriteKit 

class MenuScene: SKScene { 

    var playButton = SKSpriteNode() 
    let playButtonTex = SKTexture(imageNamed: "play") 

    override func didMove(to view: SKView) { 

     playButton = SKSpriteNode(texture: playButtonTex) 
     playButton.position = CGPoint(x: frame.midX, y: frame.midY) 
     self.addChild(playButton) 
    } 

    override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) { 
     if let touch = touches.first { 
      let pos = touch.location(in: self) 
      let node = self.atPoint(pos) 

      if node == playButton { 
       if let view = view { 
        let transition:SKTransition = SKTransition.fade(withDuration: 1) 
        let scene:SKScene = GameScene(size: self.size) 
        self.view?.presentScene(scene, transition: transition) 
       } 
      } 
     } 
    } 
}
