在Xcode SpriteKit中创建暂停菜单

private var pauseMenu: SKNode?

override func didMove(to view: SKView) {
    // 初始化暂停菜单节点
    pauseMenu = SKNode()
    
    // 添加暂停菜单节点到场景中
    addChild(pauseMenu!)
}

func showPauseMenu() {
    // 创建菜单背景
    let menuBackground = SKSpriteNode(color: .gray, size: CGSize(width: 200, height: 300))
    menuBackground.position = CGPoint(x: size.width/2, y: size.height/2)
    pauseMenu?.addChild(menuBackground)
    
    // 创建继续游戏按钮
    let resumeButton = SKLabelNode(text: "Resume")
    resumeButton.position = CGPoint(x: size.width/2, y: size.height/2 + 50)
    pauseMenu?.addChild(resumeButton)
    
    // 创建重新开始按钮
    let restartButton = SKLabelNode(text: "Restart")
    restartButton.position = CGPoint(x: size.width/2, y: size.height/2)
    pauseMenu?.addChild(restartButton)
    
    // 创建返回主菜单按钮
    let mainMenuButton = SKLabelNode(text: "Main Menu")
    mainMenuButton.position = CGPoint(x: size.width/2, y: size.height/2 - 50)
    pauseMenu?.addChild(mainMenuButton)
}

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    for touch in touches {
        let location = touch.location(in: self)
        
        if pauseButton.contains(location) {
            showPauseMenu()
        }
    }
}
