Antfarm class today again; I introduced walls — red pixels can’t be crossed. But the ants struggled to navigate around walls. We used a basic bump-along-the-wall strategy but some of them get stuck. Still, a great class — lots of complex behaviors and ideas, and some successful prototypes. See below. (code here posted on the wiki)
In other news, I left the colony foraging antfarm code running for a week, and it was still running when we started class today. There’s a population limit of 100, though, so this wasn’t “ecological balance” but it’s still interesting to see.
