tvOS pressBegan（）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'pressBegan（）'从GameViewController传递给GameScene时，代码会兴奋，但更改会被忽略。

GameViewController：

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

GameScene：

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产生“false”然后“true”。

每次你打电话给pressBegan，你都要创建一个新的Gamescene，你需要做

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