是否可以在iOS中点击标签后更改场景

Question

我有一个学校项目来制作一款进展良好的游戏，但我正在努力添加一个后退按钮。我有一个想法，点击单词返回带你进入菜单，但我不知道该怎么做。正常的"按钮"不可用，因为它是从精灵套件场景中返回的。任何建议或帮助将不胜感激。

你来了：

菜单VC.swift：

enum gameType {
  case easy
  case wobble
  case player2
}
var currentGameType: gameType = .easy
var navController = UINavigationController()
var storyBoard = UIStoryboard()
func presentMenuVC() {
  let menuVC = storyBoard.instantiateViewController(withIdentifier: "menuVC") as! MenuVC
  navController.pushViewController(menuVC, animated: true)
}
class MenuVC : UIViewController {
    @IBAction func Player2(_ sender: Any) {
        moveToGame(game: .player2)
    }
    @IBAction func Easy(_ sender: Any) {
        moveToGame(game: .easy)
    }
    @IBAction func Wobble(_ sender: Any) {
        moveToGame(game: .wobble)
    }
    func moveToGame(game: gameType) {
      navController = self.navigationController!
      storyBoard = self.storyboard!
      let gameVC = self.storyboard?.instantiateViewController(withIdentifier: "gameVC") as! GameViewController
        currentGameType = game
        self.navigationController?.pushViewController(gameVC, animated: true)
    }
}

新建文件.swift：

class MainMenuButton: SKSpriteNode {
  init(text: String, font: String) {
    let label = SKLabelNode(text: text)
    label.fontName = font
    let texture = SKView().texture(from: label)
    super.init(texture: texture!, color: .clear, size: texture!.size())
    isUserInteractionEnabled = true
  }
  override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    presentMenuVC()
  }
  required init?(coder aDecoder: NSCoder) { fatalError() }
}

GameScene.swift(添加到底部的didMoveToView功能(：

addChild(MainMenuButton(text: "go back", font: "Chalkduster"))

您可以向SKView添加普通UIButton，但这可能不是最干净的解决方案。您可以改为我们在SKLabelNode上使用触摸功能，例如 touchesBegan 和 touchesEnded .我以这种方式为SpriteKit做了一个简单的按钮实现。您可以在GitHub上查看 这里.
