From what I've been able to learn by exploring the gmod9 directory, GMod uses .res files to execute scripts that use the other games' directories to load their maps. That's how the HL2 and CS:S maps are avalible, and now that I have my hot little hands on EP1, I want to load 'em up too.
So, I tried making one of these files (each file is identical save for the name) using an EP1 map name (ep1_citadel_00), but it wasn't avalible in the map list nor via the console.
My question? Is there a way to let GMod know that I have EP1, or is there some code someone knows of that I can insert into my scripts that will allow me to do this?
Thanks
