Companion AI | AI Series Part 38

Learn how to create your very own Companion AI! In this tutorial video you will learn how to create a companion that follows the player when the player moves, rotates around the player when idle, and attacks nearby Attackable GameObjects when they come within range!

A very common mechanic in video games is to have AI that follows around the player. Some, like we're implementing today, are relatively simplistic and simply follow the player, maybe attack things, and provide guidance and a sounding board for the player throughout the game. Some are more complex with their own complex behavior trees to manage commands issued to them and responding to complex scenarios.

Today you will learn the fundamentals of creating a companion AI that can be extended to more complex use cases, or used "as is" if this is your use case!

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.
