Well, after five years with copies of Doom and Doom II, I finally got the first version of Doom Builder. And it is a confusing train wreck to me.
First off, every single time I try and make stairs, it magically thinks there should be an area without textures, and then try to hook a nearby room on ANOTHER sector, making it near-damn impossible to do multi-flooring!
I'm seriously confused right now, because trying to open a door in a map I made once made the thing crash, which makes it near-impossible to close without shutting the laptop off. Anyhow, ever done map editing like this for Doom?
EDIT: Finally! Got a new map running!
Warfair, a map set in progress - Map 01 done.
If you like being stuck in a place where the only thing that really works is a rocket launcher, welcome to my map world.
