Python3.7版---双人联机雷霆战机(2D特效+音效+道具+Linux系统)_雷霆战机联机版

作品原名称:MultiplayerGameEngine-master

作者:Tomcat(好像是这个名字没注意…)

改良者:CSDN阿坤

Hello everyone!
Today ,I will to be give everyone show a game!(英语-2级水平)
今天为大家带来的是一款双人游戏并且是2D哟,并且还附带音效道具等等,游戏环境只需要Python3以及pygame&&numpy即可完美运行，是小编从pygame上挑的一款比较不错的游戏,初始解包后直接运行虽然各种报错但是经过小编不辞辛苦的努力终于将其在Linux系统下完美运行！
因为是一款双人游戏,所以游戏的主文件分为两个　分别是Player1、Player2

由于两者内容差不多所以呢在这里只展示Player1完整代码:
