This demo is a Homing Missile example, as seen in countless shoot'em ups! The missile controller code is pretty simple, where the behavior is broken down into four states. Just Fired (missile was just launched), Homing (seeking for the target), Given up and Dead.
All the Missiles seek on the same target, the mouse pointer. Which sort of looks like a school of tadpoles Press the SpaceBar to fire more missiles and that's about it... have fun !
