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.我已经完成了对实际游戏本身的编码.现在我想创建一个主菜单,这样当游戏打开时,会有一个带按钮的菜单进入设置或开始游戏.我不知道怎么做到这一点.我应该使用故事板吗？如果是这样,我如何在xcode中实现它.感谢大家 :)

Answer 1

Swift 3.0

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)
                }
            }
        }
    }
}

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项目侧栏中的文件夹.然后在运行应用程序时让MenuScene显示进入GameViewController文件.下面有一条线viewDidLoad.if let scene = GameScene.unarchiveFromFile("GameScene") as? GameScene {将此更改为if let scene = MenuScene.unarchiveFromFile("MenuScene") as? Menu Scene {然后在您的MenuScene中,您必须有一个按钮,可以引导您进入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解释.
