🌳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~

👸PS 小编有话说

小编小时候也是下过各种棋的，比如 五子棋、泡泡棋、然后就是象棋吧~尤其是下课期间作为娱乐

活动，经常跟小伙伴儿凑一起下着玩儿。今天的话估计说起“下棋“——我居然想起了”云顶之奕”哈

哈哈！估计也有人爱玩儿。小声bb.jpg

之前疯狂沉迷——咋感觉我是个“汉子“呢！233333~不要质疑我，我真的是个女孩子女孩纸~

🌳正文

🍚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）这款中国象棋主要分为五大部分：

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！
