Click the green flag. This implements the famous "Boids" model. Boids follow three rules: align, cohere, and separate. There is no leader yet flocking patterns emerge. To make bat boids go faster, Hold the shift key while clicking Flag (puts you in turbo mode), click Flag to see bats flock.
This implements the famous "Boids" model: Boids follow three rules: align, cohere, and separate. The main point of the model is that there is no leader, yet flocking emerges. Boids only see nearby neighbors, not the whole flock, but the group self-organizes. I added wing flapping only for effect. The original Boids model is by Craig Reynolds. One fun application was bat swarms in the move Batman Returns. Thanks to boltoncode for scratch coding ideas.
