求生之路自动随机切换喷漆

其实也是伪随机，大概思路就是自动执行一个脚本，然后每隔一段时间就切换一个喷漆，因为求生在加载下一关之前，无论你切换多少次喷漆，永远还是之前的喷漆。而你过一关的时间，我们可以当作是随机的，所以就可以实现，

首先你肯定得有自己的喷漆的目录，里面放着很多喷漆文件。
比如我的是~:\steam\steamapps\common\Left 4 Dead 2\left4dead2\st

喷漆可以通过这个网站在线制作，我只是搬运汉化了一下：
https://www.fxxkcar.com/sprays/

然后你需要在这个目录，写一个脚本进去：
~:\steam\steamapps\common\Left 4 Dead 2\left4dead2\cfg

我把我脚本的内容贴出来

allspraycmd

大概的意思就是，自己定义一堆脚本的变量，然后写个命令执行切换，每切换一次就wait 1秒钟。这里的100是1秒（居然不是毫秒单位）

但是一个命令的长度有限制，所以我在后面又进行了拆分，每20个图一组。所以每一组命令就是2000，也就是20秒

这个脚本的命名叫做start_spray.cfg，所以在脚本的最后，有自己执行自己，形成递归循环。这个时候，我们只需要有个方案去启动它就行。

我们只需要在该cfg目录下，再放一个自动执行的脚本autoexec.cfg就可以了，这个脚本求生在启动时，会自动执行的。所以我们只需要在这个脚本里面，加一句执行我们上面新建的切换喷漆的脚本即可。exec start_spray.cfg

然后打开游戏，大功告成！！！
