小伙伴们大家好~

如今的游戏可谓是层出不穷，NBA 2K系列啊，FIFA系列啊更是经典中的经典，不过小编发现，赛车游戏也是深受大家欢迎啊，像跑跑卡丁车、QQ飞车，还有主机游戏极品飞车系列。

咳咳咳......小编那时候主要是最喜欢里面的人物颜值来的！

赛车游戏，通常以款式多样的车型、各式各样的赛道、身临其境的拟真度吸引了众多玩家，而玩家在游戏中需要驾驶各类赛车驰骋在世界各地的赛道上，享受肾上腺素飙升的快感。

那么接下来就给小编大家用代码编写一款《赛车CAR》小游戏吧，让我们一起来看看

一、环境安装

1）运行环境

文用到的运行环境：Python3.7、Pycharm社区版2021、Pygame游戏模块部分自带模块直 接导入不需要安装。

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

2）素材环境

音乐背景图片等：

三、效果展示

每个赛车游戏生命值三条消耗完即游戏结束。躲避相应的车子会加分。方向键左右即是移动键。
