Python实现人机中国象棋游戏

导语

哈喽！哈喽！我是木木子！今日游戏更新——中国象棋上线啦！

中国象棋是一种古老的棋类游戏，大约有两千年的历史。

是中华文明非物质文化经典产物，艺术价值泛属于整个人类文明进化史的一个分枝。

在中国，可以随处在大街上、小公园儿里等地方经常看到一堆人围在一起下棋，这就足以说明中国象棋的流行性以及普遍性有多高！

早前曾有统计，14、15个中国人当中，就有1个会下中国象棋。中国象棋的受众，可能数以亿计！

今天教大家制作一款中国象棋and想学象棋的话也可以来看看当作新手村吧~

1.游戏规则&基本玩法

1.1 基本玩法

中国象棋的游戏用具由棋盘和棋子组成，对局时，由执红棋的一方先走，双方轮流各走一招，直至分出胜、负、和，对局即终了。轮到走棋的一方，将某个棋子从一个交叉点走到另一个交叉点，或者吃掉对方的棋子而占领其交叉点，都算走了一着。双方各走一着，称为一个回合。

1.2 行棋规则

2.素材文件

3.主要代码

chinachess.py 为主文件；constants.py 数据常量；pieces.py 棋子类，走法；computer.py 电脑走法计算；button.py按钮定义。

目前电脑走法比较傻，有兴趣的朋友可以对computer.py 进行升级！不过这针对大部分的新手刚开始学象棋的话完全够用了哈~哈哈哈 如果你新手入门玩儿的过电脑就说明你入门了！

总结

好啦！文章就写到这里了哈，想入门象棋的可以先试着自己研究下，上面的教程也有说走法、行棋的规则，然后后面就是实战，自己动手跟电脑来一场对决吧~

以上就是python实现人机中国象棋游戏的详细内容，更多关于python中国象棋的资料请关注其它相关文章！
