Question

我试图用新闻开始定义TVOS中的触摸，但它不起作用。

我想连接3个功能

开始游戏
播放暂停音乐
重新开始游戏

游戏场景TVOS：

 func StartGameRecognizer(gesture: UITapGestureRecognizer) {

        if isGameOver {
        } else if !isStarted {
            start()
        } else {
            hero.flip()
        }

    }

 func playPauseMusicRecognizer(gesture: UITapGestureRecognizer) {

            let onoroff = UserDefaults.standard.bool(forKey: "onoroff")

            if !onoroff { //playing is false
                Singleton.sharedInstance().pauseBackgroundMusic()
                SoundOnOff.texture = SKTexture(imageNamed:"Sound-off.png")
                UserDefaults.standard.set(true, forKey: "onoroff")
            }
            else {
                Singleton.sharedInstance().resumeBackgroundMusic()
                SoundOnOff.texture = SKTexture(imageNamed:"Sound-on.png")
                UserDefaults.standard.set(false, forKey: "onoroff")
            }
        }

func RestartGameRecognizer(gesture: UISwipeGestureRecognizer){
    print("RestartGame")
    //Re-open GameScene

    GameViewController().TitleGameOver.isHidden = true
    GameViewController().RestartButton.isHidden = true
    GameViewController().scoreTextLabel.isHidden = true
    GameViewController().highscoreTextLabel.isHidden = true
    GameViewController().ScoreBoardTV.isHidden = true
    GameViewController().Score.isHidden = true
    GameViewController().HighScore.isHidden = true
    GameViewController().NewhighscoreTextLabel.isHidden = true
    GameViewController().HomeButton.isHidden = true
    // Singleton.sharedInstance().resumeSoundEffectClickedButton()
    GameViewController().gameDidStart()


}

GameViewControllerTVOS：

 override func pressesBegan(_ presses: Set<UIPress>, with event: UIPressesEvent?) {
    for press in presses {
        switch press.type {
        case .upArrow:
            print("Up Arrow")
        case .downArrow:
            print("Down arrow")
        case .leftArrow:
            print("Left arrow")
        case .rightArrow:
            print("Right arrow")
        case .select:
            print("Select")
        case .menu:
            print("Menu")
        case .playPause:
            print("Play/Pause")

        default:
        print("")
        }
    }
}

我如何使用它？
如何在场景之间传递功能到视图控制器？

我需要示例或提示来正确编写代码。

更新

GameSceneTvOS：

    override func didMove(to view: SKView) {

        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(GameSceneTVOS.StartGameRecognizer(gesture:)))
        tapGesture.allowedPressTypes = [NSNumber(value: UIPressType.Select.rawValue)]
        view.addGestureRecognizer(tapGesture)

        let tapGesture1 = UITapGestureRecognizer(target: self, action: #selector(GameSceneTVOS.PlaypauseMusicRecognizer(gesture:)))
        tapGesture1.allowedPressTypes = [NSNumber(value: UIPressType.PlayPause.rawValue)]
        view.addGestureRecognizer(tapGesture1)

        let swipeUp = UISwipeGestureRecognizer(target: self, action: #selector(GameSceneTVOS.RestartGameRecognizer(gesture:)))
        swipeUp.direction = UISwipeGestureRecognizerDirection.up
        self.view?.addGestureRecognizer(swipeUp)
}

**Functions :**

func StartGameRecognizer(gesture: UITapGestureRecognizer) {
        print("StartGame")

            if isGameOver {
                } else if !isStarted {
                    start()
                } else {
                    hero.flip()
                }

            }

    func PlaypauseMusicRecognizer(gesture: UITapGestureRecognizer) {
        print("PlaypauseMusic")


       let onoroff = UserDefaults.standard.bool(forKey: "onoroff")

        if !onoroff { //playing is false
            Singleton.sharedInstance().pauseBackgroundMusic()
            SoundOnOff.texture = SKTexture(imageNamed:"Sound-off.png")
            UserDefaults.standard.set(true, forKey: "onoroff")
        }
        else {
            Singleton.sharedInstance().resumeBackgroundMusic()
            SoundOnOff.texture = SKTexture(imageNamed:"Sound-on.png")
            UserDefaults.standard.set(false, forKey: "onoroff")
        }
    }


    func RestartGameRecognizer(gesture: UISwipeGestureRecognizer){
        print("RestartGame")
        //Re-open GameScene

        GameViewController().TitleGameOver.isHidden = true
        GameViewController().RestartButton.isHidden = true
        GameViewController().scoreTextLabel.isHidden = true
        GameViewController().highscoreTextLabel.isHidden = true
        GameViewController().ScoreBoardTV.isHidden = true
        GameViewController().Score.isHidden = true
        GameViewController().HighScore.isHidden = true
        GameViewController().NewhighscoreTextLabel.isHidden = true
        GameViewController().HomeButton.isHidden = true
        // Singleton.sharedInstance().resumeSoundEffectClickedButton()
        GameViewController().gameDidStart()


    }

Answer 1

您的代码存在一些问题。

1）这个代码在restartGame方法中是错误的。

  GameViewController().TitleGameOver.isHidden = true
  GameViewController().RestartButton.isHidden = true
  ...

您正在每一行创建一个新的GameViewController实例，您没有引用当前的游戏视图控制器。

2）您不应该使用GameViewController来创建UI，您应该只使用SpriteKit API（SKLabelNodes，SKSpriteNodes，SKNodes等）直接在相关的SKScenes中进行。在SpriteKit中使用UIKit，除了在某些情况下，是不好的做法。

3）你应该直接在SKScenes中使用TouchesBegan，TouchesMoved等获取触摸输入，不要使用GameViewController方法。当你在iOS上时，他们就像他们一样填补火力。

您还可以在SKScene中创建手势识别器，以便从SiriRemote获取按钮。

/// Pressed, not tapped, main touch pad
let pressedMain = UITapGestureRecognizer(target: self, action: #selector(SOMEMETHOD))
pressedMain.allowedPressTypes = [NSNumber(value: UIPressType.select.rawValue)]
view?.addGestureRecognizer(pressedMain)

/// Pressed play pause button
let pressedPlayPause = UITapGestureRecognizer(target: self, action: #selector(SOMEMETHOD))
pressedPlayPause.allowedPressTypes = [NSNumber(value: UIPressType.playPause.rawValue)]
view?.addGestureRecognizer(pressedPlayPause)

 /// Pressed menu button
let pressedMenu = UITapGestureRecognizer(target: self, action: #selector(SOMEMETHOD))
pressedMenu.allowedPressTypes = [NSNumber(value: UIPressType.menu.rawValue)]
view?.addGestureRecognizer(pressedMenu)

如果需要，您还可以使用滑动手势识别器

let rightSwipe = UISwipeGestureRecognizer(target: self, action: #selector(SOMEMETHOD))
rightSwipe.direction = .right
view?.addGestureRecognizer(rightSwipe)

let leftSwipe = UISwipeGestureRecognizer(target: self, action: #selector(SOMEMETHOD))
leftSwipe.direction = .left
view?.addGestureRecognizer(leftSwipe)

let upSwipe = UISwipeGestureRecognizer(target: self, action: #selector(SOMEMETHOD))
upSwipe.direction = .up
view?.addGestureRecognizer(upSwipe)

let downSwipe = UISwipeGestureRecognizer(target: self, action: #selector(SOMEMETHOD))
downSwipe.direction = .down
view?.addGestureRecognizer(downSwipe)

如果您正在使用手势识别器，请记住它们已添加到GameViewController（view？.addGesture ...）中，因此在添加新手势时，或者如果您更改为新的场景时，最好将其删除可能需要不同的。

退出场景或添加新的手势识别器时调用此代码。

 for gestureRecognizer in view?.gestureRecognizers ?? [] {
        view?.removeGestureRecognizer(gestureRecognizer)
    }

如果您正在寻找完全成熟的微型游戏手柄支持，那么您将需要观看有关gameController框架的一些教程。

4）尝试将类似于UserDefaults的字符串键放在某些属性中。

 enum Key: String {
     case onoroff
 }

而不是像这样使用

 UserDefaults.standard.set(true, forKey: Key.onoroff.rawValue)

避免拼写错误。

5）你应该始终遵循Swift惯例，你的一些方法和属性以大写字母开头，但它们不应该。

我建议您重新构建代码，而不是继续尝试使用GameViewController来实现这一切。应该直接在相关的SKScene中完成。

EDIT。我认为你正在调用选择器错误，试试这个。当你的函数有一个参数你会使用这个（_ :)，你试图使用（手势:)。试试这个。

 ... action: #selector(startGameRecognizer(_:))

希望这有帮助
