导语

哈喽哈喽！每天都要开心吖😋我是木木子。

今天是给大家延续上一期的内容,功能是《AI版本的贪吃蛇大作战》。

经典游戏贪吃蛇想必大家都玩过，你能想出这么经典的游戏要怎么创新才能比原作更好玩吗？

贪吃蛇大作战就做到了，而且表现异常亮眼，一时间涌现出虫虫大作战、蛇蛇大作战、贪吃蛇

等等产品，但《贪吃蛇大作战》却突围而出。

很多小伙伴儿一不小心就撞墙或者碰到边界了,直接OVER,气炸裂~

今天的话小编带大家做一款AI版本的,秀一波骚操作,想怎么玩儿怎么玩儿!游戏通关妥妥的!

一、简简单单游戏规则

贪吃蛇的规则主要有一下几条👇

小蛇通过吃食物不断增加自己的长度

小蛇的头部不能碰到自己的身体，也不能碰到边界

小蛇移动的方向只有上下左右四个方向

最核心的规则就这三条了，玩家的目标就是：尽可能的增加小蛇的长度。

二、运行环境

本次源码运行的环境:Python3.6、Pycharm社区版、Pygame游戏模块。

环境安装：pip install -i /simple/ +模块名

三、代码演示
