Simulating Flight of a Flock of Birds

In this example we simulate the flight of a flock of birds, with each bird having a simple set of rules implemented as b-threads. The example highlights

Requirements - from each bird

  • Always try to move towards the center of the flock
  • Always avoid colliding with other birds
  • When getting close to a wall - change direction - in the same "reflection" angle
  • When the "Scare" button is hit - fly away from the center of the flock.
