iOS点击标签后是否可以切换场景？

Question

我有一个学校项目要制作一款运行良好的游戏，但我很难添加后退按钮。我想点击“返回”一词将您带到菜单，但我不知道该怎么做。正常的 "button" 不可用，因为它正在从 sprite 套件场景返回。任何建议或帮助表示赞赏。

Answer 1

您可以将普通 UIButton 添加到 SKView，但这可能不是最干净的解决方案。您可以改为使用 SKLabelNode 上的触摸功能，例如 touchesBegan 和 touchesEnded。我用这种方式为 SpriteKit 做了一个简单的按钮实现。您可以在 GitHub here.

给你：

MenuVC.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)

    }
}

NewFile.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 函数）：

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