Heya, I'm Daeval.
A long, long time ago in a galaxy far, far away, I was also Sir Jaster @Ni!.
I haven't messed with Hammer much since it was called Worldcraft, but I've been starting up again with the release of Team Fortress 2.
Not doing that so much anymore.
For the moment, I'm poking at the Source Engine.
I may update / create things here as I explore the code. There are a lot of really specific tutorials here, but there seems to be very little in the way of fundamentals.
Works in Progress..
Nothing to see here. Move along...
