Learn how to code Boids AI in Scratch (originally created by Craig Reynolds in 1986 to simulate the realistic flocking behaviour of birds). But this can be used for swarms of aliens, hordes of Zombies or waves of enemy NPCs, so you too can bring amazing artificial life simulations in to your games. Follow the basic 3 steps, Separation, Cohesion, & Alignment and get 50+ boid clones interacting with each other and with your mouse - Now Scratch on Guys!
