well i was working on footprint manipulation but it's a pain to edit and nobody else who is more expert in that sort of thing is really interested in it...i've had a lot of jass learning to do too, i still have a long way to go in that so i have considered that to be a minor thing. i was indeed trying eventually to do something like what you're trying to do. if i ever figure it out, i'll let you know. you can pm me or post here if you want me to try to get you some notes on some stuff i found out about it. you could also do search on the forum or google for "footprint manipulation" and look for my posts.
i might be wrong though, you might be talking about something else, but i think that's what you meant...
