The pursuer and evader are initialized with identical random position and velocities. The green pursuing vehicle uses seek to approach this estimated target position, while the red evading vehicle uses flee to escape from it.
Effective prediction is indicated when the target symbol slows to a stop.
When the green pursuer reaches the gray quarry, the target symbol will disappear, and the demonstration is restarted. Each vehicle's velocity is indicated by a magenta vector, its steering force is indicated by a blue vector.
