Heya.

I've bee toying, for more or less one year, with a small idea for a weapon mod for Doom/Doom 2. I've been done a little(ish) research, and most stuff done seems to come either from map editors or a unknown source of knowledge somewhere in the internet which I assume is people messing around with Doom source code for several years.

So, what I'm trying to find is some kind of source, wiki, tutorial, whatever, to add new, non graphic, stuff to doom. For instance, each time I kill a zombie, I would like a message to pop in screen. Or add clip/reload functionality like in Brutal Doom.

I'm used to code (hell, that's supossed to be my job!), so I'm not afraid of some C/C /Whatever script or programming language uses the modern source ports, if any. But as I said, the knowledge to "get into the guts" of Doom seems to be hidden somewhere I can't find.
