我正在制作一个pacman游戏，我在一个数组中有一个MAP，我在地图中指定不同的值来绘制不同的图像，以便创建一个pacman地图......但它会在整个地方闪烁< / p>
任何帮助识别问题都会很精彩
我意识到这是很多阅读，但我已经看了好几个小时而没想出来......我是编程的新手，所以我认为更有经验的眼睛真的可以让我受益

答案 0 :(得分：2)
你需要双缓冲，问题是java用背景颜色绘制画布，然后放上grahpics指令，所以，如果你需要更改图像，你可以在“隐藏的图像”中做到这一点，当它准备就绪时将其打印在画布区域中，用新渲染的图像替换图像。 更多信息Double Buffer in java。 编辑： 几乎忘了，真的很容易做到，这里有一个例子double buffer example
