Basic team forcing all controlled with a single file. Hopefully there are no bugs, this hasn't been tested a lot, or at all.
A compiled version can be found here.
To run the backend server you need to install NodeJS and run it via node server.js, which can be found inside the server folder.
The team_setup.txt file needs to be located in this folder: <csgo_ds>/csgo/addons/sourcemod/team_setup.txt. Its setup is very specific but following the example team_setup.txt should be easy.
If you want to use avatars the backend server is required. The backend server requires ImageMagick to turn PNG's into RGB files.
Simply put a file with the SteamID64 as name into the avatars folder. From there the server will automatically convert them into RGB files upon request and send them to your gameserver.
