Java 鼠标运动监听器

我是Java编程的初学者。我正在尝试创建一个棋子游戏，玩家可以移动自己的棋子。问题是，当一件物品被移动时，所有人都会移动它。我真的很感谢你的帮助。谢谢

您有一个复制粘贴错误。您的PieceManager类与game类相同，因此抱歉将修复

while（true）

循环在此事件驱动GUI中没有位置。看起来您正试图将horn线性控制台代码嵌入到事件驱动GUI中，而这绝对是您不想做的事情。我不知道您的意思，我首先要看一下和。Swing使用一种被动渲染算法，对于您正在做的事情来说，这已经足够了。不要使用

getGraphics

，在这种情况下，这确实不是应该做的事情
