基于Python+Pygame实现经典赛车游戏_Python

导语

哈喽！哈喽~我是木木子，很久没给大家更新游戏的类似啦——

有粉丝投稿，说最近由于受疫情影响封闭在家不能离开小区，前不久刚刚报名的驾照考试只能无线延期，在家里还是挺无聊的，“憋在家里没事干的时候去打打游戏写写代码还挺好的。

于是，小编灵机一动，就有了今天这款简易版本的《赛车计划》也就是咳咳咳.......

通俗点儿就是一款代码写的一款关于汽车的小游戏，由于小编的思路跟编程的学习跟不上！！

SO，我尽力了......只能展示出这样的一款赛车游戏~有大神的话可以优化啦~

一、环境安装

1.各种素材（图片）

基于Python+Pygame实现经典赛车游戏

2.运行环境

小编使用的环境：Python3、Pycharm社区版、Pygame模块部分自带。

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

二、代码展示

这款游戏代码特别多啦，小编这里就主要展示一下主程序运行的代码，全部的就找我文末拿哈~
