swift - tvOS pressesBegan() 未在 GameScene 中更新

Question

在我的 GameScene 中，当我使用“touchesBegan()”更新变量时，它工作正常，但是当我将“pressesBegan()”从 GameViewController 传递到 GameScene 时，代码会变得很兴奋，但更改会被忽略。

游戏 View Controller :

class GameViewController: UIViewController {
    ...
    override func pressesBegan(presses: Set<UIPress>, withEvent event: UIPressesEvent?) {
        let scene = GameScene(fileNamed: "GameScene")
        scene?.pressesBegan(presses, withEvent: event)
    }

游戏场景:

class GameScene: SKScene {
    var test = true
    ...
    override func pressesBegan(presses: Set<UIPress>, withEvent event: UIPressesEvent?) {
        test = false
        print(test)
    }
    override func update(currentTime: CFTimeInterval) {
        print(test)
    }
}

此代码将在控制台中导致“false”然后“true”。

每次调用 pressesBegan 时，您都在创建一个新的游戏场景，您需要执行以下操作

override func pressesBegan(presses: Set<UIPress>, withEvent event: UIPressesEvent?) {
    if let skView = self.view as? SKView
    {
        skView.scene?.pressesBegan(presses, withEvent: event)
    }
}
