欢迎大家来到IT世界,在知识的湖畔探索吧!
导语
大家好，我是会敲代码且万能的木子酱!!
不知不觉，2022年已经过去了四分之一了，相较于去年，今年更新的新游戏貌似有点儿趋于平
淡了。这次虽然没有大型游戏，但是今天给大家制作一款玩法有趣的《星际大战》游戏给大
家。下面我就带领大家敲敲一下本月值得推荐的好玩的游戏啦~
木子有话说——
好多小伙伴总是遗憾错过宝贝资源，怎么办？！
请喜欢编程方面的小可爱关注下我啦★ ，下次出新的内容就可以优先学习拿源码哦~
感谢大家的支持。木子酱为大家准备的之前的文章源码都在私信小编06即可啦~

一、环境安装
1）各种素材（图片等仅部分）
资料挺多滴，等下就展示小部分素材哈……
2）运行环境
小编使用的环境：Python3、Pycharm社区版、Pygame模块部分自带就不
展示啦。
模块安装：pip install -i https://pypi.douban.com/simple/ +模块名欢迎大家来到IT世界,在知识的湖畔探索吧!
二、代码展示
1）配置文件
窗口大小、素材等资料导入：
