本文实例讲述了java实现的中国象棋游戏代码,分享给大家供大家参考,具体代码如下
一、实践目的:
1.鼠标点击、拖动等事件的应用与区别
2.棋谱文件的保存与读取
3.完善象棋的规则。
二、实践内容:
中国象棋历史悠久,吸引了无数的人研究,现对中国象棋的对战和实现棋谱的制作做如下的设计和说明,供大家参考学习。
1、机机对弈,红方先手。在符合规则的情况下拖动棋子到目的地,松鼠标落子。
人人对弈图
2、制作棋谱,选择制作棋谱菜单后,对弈开始,并记录了下棋过程。
选择“制作棋谱”菜单
棋谱制作完毕红方胜出
一方胜出后弹出胜利消息对话框。点击确定后,选择“保存棋谱”菜单,弹出保存文件对话框。
保存棋谱对话框
3.演示棋谱,选择演示棋谱菜单后,弹出打开对话框,选择保存好的棋谱,开始演示。
演示棋谱对话框
演示棋谱过程(自动和手动两种)

四、总结与要求
1.理解8个文件,没有太复杂的代码。
2.理解鼠标的MouseListener,MouseMotionListener两个接口的区别,五子棋的实现不需要MouseMotionListener。
3.使用LinkedList记录棋谱的方法。
