【Pygame小游戏】刷爆朋友圈的《贪吃蛇大作战》附上史上最强攻略，请查收~（附：源码合集）_游戏开发

“First Blood——Double Kill——Trible Kill”熟悉的音效！

很早之前的游戏黑马——贪吃蛇大作战，借着大家对诺基亚贪吃蛇的怀念对规则进行小改变后

一次又一次唤醒了大家对它的怀旧与热爱，不用猜就知道今天给大家介绍什么游戏了吧~

大家好，我是木木子吖，每天都给大家收集最好玩的游戏！

关注我，从此你再也不用去费力找游戏（白嫖项目源码哦）了，最好玩的游戏点击即玩！

今天推荐的游戏是贪吃蛇大作战小程序游戏哦????

写完这款《贪吃蛇》小游戏，下一个系列就是做一款AI版本的自动贪吃蛇啦！有时间给大家慢

慢升级，嘿嘿！

一、准备中

▲游戏玩法

1、控制方向键走位你的小蛇，吃掉地图上彩色的小点，就会变长哦。

2、小心!小蛇碰到界面壁的时候游戏立马结束了哦！

3、一局定胜负，和小伙伴们比谁更长吖！

▲环境安装

本文用到的运行环境：Python3.7、Pycharm社区版2020、Pygame游戏模块部分自带模块直

接导入不需要安装。（如果需要安装包软件、激活码或者遇到问题的话可以私信我哈！）

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