前言?

嗨！我是栗子同学。很久不见甚是思念！我回来啦~

今天给大家写点儿什么呢？！嘿嘿，其实这么久没写代码啦，手都不会打字了，代码都不会敲

了，容我慢慢道来！先来点儿简单的吧（其实是没思路，上次写剩下的一个无敌狙击手的游戏

代码小小的改编了一下下，偷懒了哈，因为不知道写啥了，不要打我.jpg）

等我灵感了就好好给大家写，先练练手哈!有爱的源码，可以评论下下次说不定就写了撒!

今天教大家写一款简单的小游戏：《吃掉一切》让我们马上开始叭👇

所有文章完整的素材+源码都在👇👇文末公众hao自取哦!

正文

本文是基于pygame写的一款界面简单的小游戏哈！

一、运行环境

?1）环境安装👇 Python3、 Pycharm 、tkinter、Pygame模块部分自带模块就不展示啦。

（如需安装包、激活码等直接私信我即可安装问题解答都可以的哈~）

第三方库的安装：pip install pygame 或者 带镜像源 pip install -i

https://pypi.douban.com/simple/ +模块名

2）素材（图片：食物跟吃东西的人）

感觉食物跟人美少女不是很配来着，哈哈哈，将就一下叭，大家可以更换图片的啦！

二、主程序
