Our own collection of tools and background material can be found here:
ftp://12.39.48.62/UScript/
at least until our generous friend decides to take down the public FTP, but I'm sure Carnage could find a mirror...? Warning though, it's quite a large archive! And I'm sorry for NOT sorting it, it's kinda just what I collected myself over the years.
Hmm how to get started? The best is, read exisiting codes! UScript is an object oriented language, so any knowledge about C++ or JAVA will help indefinitely. That's kinda how I got into that... along with the docs on that FTP
Other areas such as modelling, mapping or texturing are totally out of my horizon so go ask someone else
My namesake "Wolf" has some mapping tutoraials which are widely used though.
