A while back, I read an article on using weightmaps to control ai movement, particularly in an RTS environment. I can't find the article again, so perhaps someone here read it? I'm not asking for a list, there's a specific article I'm looking for, and so far I haven't found the magic query on google to find it.

I suspect you actually mean influence maps, which have some sort of 'weight' at each point on the grid. My mind-reading skills are not great so I can't tell exactly which article you read but maybe one of these will help: The Mechanics of Influence Mapping, Influence Maps, Influence Maps I, etc.

Pretty much Google is a mind reader. – Byte56 Jul 31 '12 at 2:04
Thank you so much, the third link is exactly what I was looking for! I'll make sure to bookmark and remember the term "influence map"... – Bloodyaugust Jul 31 '12 at 2:58
