前言

今年，已经是我们和新冠疫情共处的第三年。不聚集，不远行，成了疫情之下的生活常态。

但意外和明天，你永远不知道哪个先来。

就在我们以为寒冬将尽，盛春即归时，各地的新冠病毒跟商量好了似的集体冒出来，搅乱了原

本相对平静的生活，也剥夺了本就在重复着“两点一线”的单调生活里所剩不多的那点自由。

今天小编给大家用代码带来一个抗击疫情的小游戏，愿疫情早日结束，回归平静的生活！

正文

一、环境准备

1）图片素材

2）环境安装

本文用到的环境：Python3、Pycharm2020、Pygame模块以及部分自带的模块。

（环境安装包如果需要的话可以滴滴小编的啦，有问题也可以私信我啦，有时间的话都会给大

家解答的哦~）

模块安装：pip install +模块名

二、效果展示

1）游戏界面

2）运行游戏

《抗击疫情》这款小游戏是分为三个关卡的，分为简单L、中等难度为M、最难的为H。这下

面的截图为最简单的啦~大家可以自己拿代码试试的哈

三、代码展示

1）配置文件

配置文件 import os 屏幕大小 SCREENSIZE = (640, 640) 图片素材根目录 PICTURE_ROOT_DIR = os.path.join(os.getcwd(), resources/pictures) 字体路径 FONTPATH = os.path.join(os.getcwd(), resources/font/FZSTK.TTF) 定义一些颜色 BACKGROUNDCOLOR = (255, 255, 255) RED = (255, 0, 0) BLUE = (0, 0, 255) BLACK = (0, 0, 0) FPS FPS = 40 随机打乱图次数 NUMRANDOM = 100

2）主程序
