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

• Multi-agent activity
• Emergent group behaviors - emanating from individual agent behavior
• Implementation of animation with BPJ - and handling of associated design issues.
• http://www.wisdom.weizmann.ac.il/~bprogram/videos/flock25Gather.avi | Movie: 25 birds gathering and flying
• Movie: Birds disperse in reaction to a "scare" action

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.

A video example of the result can be seen here ** add link **
