This is my very first project with Greenfoot. The ants come in at random times, at an equal random rate from two nests. Black and red ants behave exactly in the same way - they walk around randomly and when they meet a specimen from the other population there is a short fight, with exactly 50% chance of survival. The simulation ends when one ant population is wiped out.
