Your gamemode must be sandbox derived.

[Parilar]

Oh okay and is there any way to use it with other gamemodes ?

[Kefta]

You can define base_gmodentity in your gamemode: https://github.com/Facepunch/garrysmod/blob/master/garrysmod/gamemodes/sandbox/entities/entities/base_gmodentity.lua

Sounds good, i want to use this mod with TTT. I just have to add base_gmodentity.lua or do i have to edit a file to load the lua file ?

[Kefta]

Just add the file to the ~/terrortown/entities/entities/ folder.

New update removed the base_gmodentity requirement. (Github only atm)
Thanks for pointing it out.
