hey folks here is a nice little simulation of Boid behavior that only uses Bullet and Sine wave behaviours...
its not perfect but its very simple method of getting Flocking and boid behaviour without too much effort
free to use and alter in any project..
no credit necessary unless you feel like it
best wishes and hope you like it
