Hiding AI - Take Cover Behind World Geometry | AI Series Part 29

Learn how to make NavMeshAgents find valid cover spots from another target object. In this video we'll specifically use a Player, but this can be applied to hide from any object - a grenade for example. Together we'll create a configurable script that allows us to refine which objects are valid to hide behind and exclude those that are not.

We'll add the following possible configurations:

⚫ Layers of objects to consider for cover, and to hide FROM

⚫ Radius to check for objects to hide behind, and FROM

⚫ Size of objects to hide behind

⚫ Distance from object cover must be

⚫ How good of a hiding spot it must be to take cover

⚫ How frequently to check for new hiding/cover spots
