很抱歉，如果这是一个菜鸟问题，但这是第一次制作游戏而我只是想知道如何在游戏环中调用，我在Keylistener类中创建它，但每当我运行它时因为run（）方法中的infiniate while循环而冻结，但我也想在游戏开始时调用它，所以我可以在整个游戏中看到ticks / fps，如果你们需要任何代码，这里是我的代码其他类请说谢谢:)更容易我只是要显示keylistener类所以它不是很多代码供你排序，只是让你知道我的网格使用数组的方式JLabels打电话给WizardCells只是为了让你知道并且我使用了图像用于我没有使用BufferedImage的图标，无论如何我认为这就是你需要知道的全部感谢:) btw timePassed是Delta我只是不喜欢名字delta haha

您应该使用模型 - 视图 - 控制器方法。让您的击键导致模型的更新，并且独立于此，具有根据模型所处的状态更新显示的计时器循环。该更新通常采用在UI中处理的重绘请求的形式。线。重绘方法（因UI包而异）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。
