【Python游戏】Python基于第三方库pygame实现一个魂斗罗小游戏，毕业设计必备 | 附源码
前言
halo，包子们下午好
今天给打击整一个魂斗罗小游戏
很多小伙伴接触魂斗罗应该是在小时候的一个手柄游戏上面吧
我记得作为90后的我，玩这一款游戏是在小学的时候
废话不多说，直接上才艺
今天给大家直接安排
相关文件
关注小编，私信小编领取哟！
当然别忘了一件三连哟~~
开发工具
Python版本：3.7.8
相关模块：
pygame模块；
random模块；
以及一些python自带的模块。
环境搭建
安装Python并添加到环境变量，pip安装需要的相关模块即可。
效果展示
游戏玩法
玩法
WASD 是控制人物的移动，J是发射子弹 boss 是不知火舞 ，哈哈
做了一点小改变，不过问题不大很大
