2、编译
1）新建一个虚拟环境安装pygame，pyinstaller两个库
2）使用pyinstaller打包
说明一下，pyinstaller打包，会加载环境里的全部内容，所以需要单独新建环境，这样在dist生成的exe文件会比较小。
pyinstaller 参数和使用说明可以参考：使用Pyinstaller打包exe文件详细图文教程
不用看.spec文件格式，用不到。
3）生成结果
说明：运行程序是没有窗口图标和声音的，需要dist中放一个bfa.mp3.这个是在465行。可以修改成自己的内容。
2.有了可运行程序，使用RAR压缩工具将资源和程序打包成独立可执行exe
1）将声音，图标，python打包生成的exe 打成一个rar
2）打开 dist.rar ，工具拦选择“自解压格式”
完成以上配置后选确定，两次。这时在目录下会生成 dist.exe。这时可以运行查下一下效果。
3.将dist.exe配置成系统屏幕保护
1）将dist.exe 修改成 dist.scr 复制到 C:\Windows目录下双击运行
2）回到电脑桌面，鼠标右击，选择个性化打开如下图：
加载全部内容
