Having programmed the Flipping Blocks game and scratched the surface of Unity3d’s capabilities I started experimenting with Unity’s physics functionality. Unity does so much of the heavy lifting that I was able using about 150 lines of C# code to program a nice 3d swarming simulation based on a few simple rules:
- try to follow the leader
- don’t get too close to your neighbours
- slow down if you go too fast
- don’t get too far from the camera (leader only)
It makes your hardware work quite hard. I can watch it for ages, it’s quite fascinating.
