I started writing a crossfire map-making tutorial, focusing on detailed description of all those freaky object-attributes. Take a look at < http://mids.student.utwente.nl/~avogl/map_guide/ >. It's not even half done though. Currently it covers 18 object-types, about 130 more to go... :P As you can imagine, I would greatly appreciate any support I can get. (I permanently need to look into the source, that is very time-consuming.) But I don't have problems doing it alone either. It's just likely to take me a few months then, since I don't feel like working on that page day and night :) Honestly, I don't even want to make any promise that I'm gonna finish it. But I think every single bit I write will help. Andreas V.
