目录

首先,在python上 安装pygame

然后,创建文件夹 要注意分级别​

 插入的图片

主函数 Aileen_invasion的文件

创建外星人aileen的文件

子弹bullet的文件

按钮button的文件

 游戏数据game_stats的文件

游戏分数scoreboard的文件

游戏设置settings的文件 

游戏飞船ship的文件

​编辑 全屏模式下的游戏

​编辑

小窗口下的游戏

首先,在python上 安装pygame

资源--->https://download.csdn.net/download/Aileenvov/88301424?spm=1001.2014.3001.5503

然后转到228页,根据步骤进行安装

然后,创建文件夹 要注意分级别

 插入的图片

插入图片:需要注意图片的大小比例,否则可能显示不出来,这需要根据系统屏幕大小进行设置,

将所需要的图片和音乐拖到对应的文件夹,这是我的图片
