So, I figured I'd show you guys what I've been working on lately: http://www.youtube.com/watch?v=wuUB_EZpljM
This is a screen-capture of my latest project running on the iPad simulator.
To basic idea is that ants can only see in their FOV (which I show in the video) and they follow pheromone trails but also drop pheromone themselves. Feel free to look into the Ant-Routing algorithm, there should be plenty of information on it.
I've been working on it for about 2 months or so now and it is far from complete. It's mainly just the bare-bones basics right now. I've also got impassable terrain working (although it's a bit buggy).
Also, Objective-C takes a bit to get use to. Also programming on Macs are weird (why would Apple make the # key Alt+3 and not show it on the keyboard when you need it to program in Objective-C?!).
So... any questions?
