I'm currently developing an engine similar to that used in the Sierra
games under DJGPP. Part of this engine is some pathfinding code which
lets a character find a way around the objects in a room. A room is
just defined as a bunch of objects with boundary polygons and an x,y,z
position. The code will be available from my website within the next
couple of days (actually its there, there is just no link: try
http://members.xoom.com/brett_porter/pathfind.zip). This might help
you out. If you are developing a game in the same sort of style I'd
like to hear about your experiences, and I'd love to help out (and ask
for help) wherever possible.

A final note is that this should not really be posted to the DJGPP
group. I'm just as bad, following it up, I suppose... and I realise
you tried rec.games.programmer first. Ive given up trying anything
there because 90% of the threads are arguing about something started
by a blatant troll and usually resort to swearing, childish name
calling and racial abuse from what I've seen. There are a couple of
particularly bad offenders and I believe a few people (not myself)
have attempted to get in contact with their ISPs about cancelling
accounts.

That's why I like c.o.m.djgpp, everyone here is so nice :) We've only
had one use of profanity this year as far as I remember and he got
shot down in flames by two or three of the most respected members of
the group.

Anyway, back to the point. My page will be totally up and running in a
day or two (I hope!), but you can grab that source now. Please let me
know about your experiences with it.

Cheers,
Brett
