怎么使用Python+Pygame实现走四棋儿游戏(pygame,python,开发技术)

一、游戏解说

“走四儿”大部分活跃在山东济南、聊城、菏泽等地，是一种棋类游戏，特别适合儿童试玩。

在一个4×4的棋盘上，双方各有4子，分别摆放在棋盘两个最上面的两端线的四个位置上。下图

就是“走四儿”开局的样子。

二、游戏规则

“走四儿”的游戏规则是：

1．双方轮流走，每一步只能在上下左右中的一个无子的方向上走一个格，不能斜走。如果一方无法移动，则由另一方走。

2．当甲方的一个子移动到一条线上之后，这条线上只有甲方的两个子和乙方的一个子，且甲方的这两子相连，乙方的子与甲方那两子中的一个子相连，那么乙方的这个子就被吃掉。

下图是可以吃子的样式例举：

3．少于2个子的一方为输者。双方都无法胜对方就可以认为是和棋。

三、环境安装

1）素材（图片）

2）运行环境 小编使用的环境：Python3、Pycharm社区版、Pygame、 numpy模块部分自带就不一一 展示啦。

模块安装：pip install -i https://pypi.douban.com/simple/+模块名
