如何修復動畫（Java）需要幫助=]

程序檢測到左右箭頭鍵。如果按下這些鍵中的任何一個，那麼作爲GImage類實例的我的Knight對象會穿過一組字符串（這些字符串是我的Knight對象動畫的目錄路徑。）如何修復動畫（Java）需要幫助=]

我的代碼的問題是，我似乎無法用我想出的java代碼找到適當的流體動畫，當我按下箭頭鍵時，動畫循環快，然後慢下來，但當我擡起箭頭鍵並再次按下時，動畫仍然快速循環然後它會減慢。

每個運動動畫製作具有動畫的4幀。

任何提示表示讚賞。

我不知道爲什麼這是倒票;引用使用的API的+1;考慮改進可讀性的格式。 – trashgod 2012-08-17 05:06:52

您致電pause()阻止event dispatch thread。在此情況下，請使用acm.util.SwingTimer在計時器的ActionListener中調整動畫。

謝謝我會測試一下。謝謝你的提示！ – Nicholas 2012-08-17 05:01:49
