如何在整个程序中调用我的游戏循环以及在tick（）中放入什么

Question

好的，很抱歉，如果这是一个菜鸟问题，但这是第一次制作游戏，我只想知道如何在gameloop中调用，我已经在Keylistener类中创建了它，但是每当我运行它时，它都将冻结到run（）方法中的无限while循环，但是我也想在游戏开始时调用它，这样我就可以看到整个游戏的滴答/ fps，这是我的代码，如果你们需要其他任何类，请这么说，谢谢:)为了更容易，我将显示keylistener类，因此不需要太多代码来进行排序，因此，您知道我制作网格的方式是使用名为WizardCells的JLabel数组就是这样，这样您就知道了，我为不使用BufferedImage的图标使用了imageicons图标，无论如何，我想这就是您需要知道的全部了：) btw timePassed是Delta我只是不喜欢这个名字delta haha

您应该使用模型视图控制器方法。 让您的按键动作导致模型更新，并且与此无关，具有计时器循环，可以根据模型所处的状态来更新显示。该更新通常采用在UI中处理的重画请求的形式线。 repaint方法（在UI包中有所不同）将调用其他方法来调整UI中的对象和/或在画布上绘制以获得更细粒度的UI。
