# Flocking

Apply flocking rules to program a school of fish, confine them to a tank, and add obstacles to the simulation.

In this tutorial students will learn the about the three rules used for simulating flocking and begin setting up a project to create a flocking fish scene.  Next, students will program their fish with more flocking mechanisms to get them to follow the simulated rules and keep them confined in a boundary.  Finally, students will complete the flocking simulation and add obstacles to the fish tank.

## Flocking Part 1: Setting up Fish Agents

In this tutorial, students will setup a scene with animated fish and spawning functionality before moving onto the next tutorial which will implement flocking.

## Flocking Part 3: Adding goal locations and speed variety

In this tutorial, students will learn how to add variety to the fish schooling by adding moving goal locations and variable speeds.

## Flocking Part 4: Containing Fish in a Tank

In this tutorial, students will learn how to add a bounds to the flocking simulation to keep fish contained in an area.
