Ginger Booth had a model with continuous space, and we were talking a
couple of years ago whether it would be possible to make a general
purpose swarm library. Maybe we should talk about it again.
I deal with it by having the agents locate themselves in real-valued
spaces, but when I draw on the grid, they get placed at approximate
integer-valued positions. I don't have any algorithms for "find agents
within X units" that are any good, I just search on the discretized
grid.
