我正在做一个类似游戏Unblockme的程序，你必须移动块并将红色块移到另一侧以移动到下一个级别。现在我加载程序，单击第一级然后我可以为Redblock选择radiobutton，当我尝试然后单击右移Jbutton，它在动作监听器中我编程它移动，并且它没有尝试过喜欢3天，我仍然卡住了。谢谢我将包括我加载和绘制图像的加载图片类，我的labelframe与actionlisteners和其他一切。我发布的第一堂课是labelframe，然后是装载图片课。

这个example使用按钮或键盘移动一条线。您可以在drawImage()而不是paintComponent()中致电drawLine()。必要的步骤是在每次更改位置后调用repaint()。
