Haven't posted in a while, recently I wanted to learn how to animate a group/flock of fish in Unity.

I ended up using shadergraph to animate the individual fish and created a script to control the group motion at run-time.

The flock simulation is called Boids, and it was originally developed by Craig Reynolds. The code I wrote is relatively simple (has 3 main steps).

1) Avoid colliding with other fish

2) keep average alignment of nearby fish

3) move to the average position of nearby fish
