I mean FOW like in the strategies. For ex. - i saw enemy's building, but when i don't see this place, i still can see the building, even if it already destructed. And when i see this place again i see that there's nothing left.
I'm working on this model of fov right now combining LOS and Canvas, still some problems. Maybe anyone already implemented this, and can donate a prototype?
Here's my FOW implementation prototype http://www.box.net/shared/9tzdjybr3c
