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. ## Materials - [S0906Starter.unitypackage](https://storage.googleapis.com/learn-platform-bucket-production/tutorial/b0532145-eb3e-5db8-b4c7-c85ac60b1b35/versions%5B_key==%22a75bff9d01a7d1fa30ad6016c5c6e395%22%5D.materials%5B_key==%22063a7be4c732%22%5D.file/S0906Starter.unitypackage_20260323_211116.gz) - [S0909SolutionU6.zip](https://storage.googleapis.com/learn-platform-bucket-production/tutorial/b0532145-eb3e-5db8-b4c7-c85ac60b1b35/versions%5B_key==%22a75bff9d01a7d1fa30ad6016c5c6e395%22%5D.materials%5B_key==%22d223cb420420%22%5D.file/S0909SolutionU6_20260323_211140.zip) ## 1.
