将MouseEvents从一个Java文件链接到另一个Java文件
一些背景我正在用java开发一个游戏，我正在使用Netbeans来构建它。我目前有3个java文件将MouseEvents从一个Java文件链接到另一个Java文件,java,swing,mouseevent,chess,Java,Swing,Mouseevent,Chess,一些背景我正在用java开发一个游戏，我正在使用Netbeans来构建它。我目前有3个java文件 App.java Board.java Piece.java 目前，当它运行时，它向用户显示一个简单的棋盘，所有棋子都在正确的位置等 这些都是在Board.java中完成的 我的问题是棋子的移动是在棋子中完成的。java目前我有白色棋子的编码和控制它的鼠标事件，但当我运行程序时，棋盘会与棋子一起出现，但没有一个棋子移动，甚至白色棋子也没有移动 我很难理解为什么，我想也许我没有把它们和黑板或者其

The Pawn is the only piece that cannot move backwards in chess...so be careful when committing
a pawn forward. A Pawn is able to take any of the opponent’s pieces but they have to be one
square forward and one square over, i.e. in a diagonal direction from the Pawns original position.
If a Pawn makes it to the top of the other side, the Pawn can turn into any other piece, for
demonstration purposes the Pawn here turns into a Queen.
