These points are not set directly from user scripts but a NavMeshPath with points correctly assigned is returned by the NavMesh.CalculatePath function and the NavMeshAgent.path property. Lessons learned from the Paradox podcast - Season 4, How to find the shortest path on a navmesh, How to make characters follow the shortest path, "Simplified 3D Movement and Pathfinding Using Navigation Meshes" - which is a very good article found in the book "Game Programming Gems". 0. When baking is complete, you will find a NavMesh asset file inside a folder with the same name as the scene the NavMesh belongs to. Once your level or terrain is setup with a NavMesh you can easily add a NavMeshAgent component to your non-player character(s) and have them move around intelligently throughout your game..
