Surround AI - Circle a Target | AI Series Part 27

Learn how to make your NavMeshAgents SURROUND their target, instead of just running to the center point of their target. In this tutorial we'll be implementing a simple solution to the "dumb AI" problem where your NavMeshAgents get bunched up and create a funnel or wedge when trying to follow a target.

We'll implement a simple AI Manager singleton that will set the destination of NavMeshAgents to specific points around the player at a defined radius. We'll learn a little bit of math about how the Unit Circle and Mathf.Sin (Sine) and Mathf.Cos (Cosine) trigonometric functions can help us solve this problem without a bunch of raycasting or list manipulation.

As usual with the AI Series, we're using the NavMesh Components: https://docs.unity3d.com/Manual/NavMesh-BuildingComponents.html not the built-in navigation system.
