如何在整個程序中調用我的gameloop以及在tick中放什麼（）

Question

好吧，非常抱歉，如果這是一個noob問題，但這是第一次製作遊戲，我只想知道如何在gameloop中調用，我已經在我的Keylistener類中創建了它，但是每當我運行它時，它都會因run（）方法中的infinate while循環而凍結，但我也想在遊戲啓動時調用它，以便可以看到整個遊戲中的蜱/ fps，這裏是我的代碼，如果你們需要任何其他類，請說謝謝:)更容易我只是要顯示keylistener類，因此它不是很多代碼來排序，只是爲了讓你知道我製作網格的方式是使用名爲WizardCells的JLabel數組，所以你知道，我使用了圖標我沒有使用BufferedImage的圖標，無論如何，我認爲這就是你需要知道的全部內容，謝謝： ） BTW timePassed是三角洲我只是不喜歡這個名字三角洲哈哈

你應該使用一個模型 - 視圖 - 控制器的方法。讓你的擊鍵導致模型的更新，並且獨立於此，有一個定時器循環，根據模型所處的狀態更新顯示。該更新通常採用在UI中處理的重繪請求的形式線。重繪方法（在UI包中變化）將調用其他方法來調整UI中的對象和/或在畫布上繪製細粒度的UI。
