井字游戏(shell高级版)

 

    大家小时候大概都玩过井字游戏，就是双方在九宫格里面轮流下棋 ，先构成三点一线（横线、竖线或者斜线）的一方取胜。有点经验的人都知道，这样简单的游戏根本是不分胜负的，除非就是某一方特别粗心，才会让你有获胜的机会。

 

 

    于是，我们研究了一种新的井字游戏，即所谓的高级版。棋盘为 9×9 的 81宫格，分为9个九宫格。

 

    取胜规则：

        1、在任意一个九宫格中先构成三点一线（横线、竖线或者斜线）的一方取胜。

        2、轮到对方下棋且对方无子可下，则本方获胜。

 

    下子规则：

        1、从左到右、从上到下分别编号9个九宫格为1—9，则先下棋者只能在第5九宫格范围内下子。

        2、若对手在第 i 九宫格的第 j 位置处下棋，则紧接着本方必须在第 j 九宫格范围内下棋。

 

 

    游戏是shell脚本写成的，测试环境为bash，wsad控制方向键移动，f、空格、回车、Tab为下棋动作，x退出游戏，n开始新的游戏。详细可以研究一下代码，十分简单的。
