How to understand that a point belongs to NavMesh?

Question

Unity

Hello. Question about NavMesh. I want to randomly create objects on the map, but in such a way that they appear where the player can pass. Is it possible to get a random point on the NavMesh, or to understand if the NavMesh point belongs or not.

Answer 1

Either you need to ask the agent on the mesh if it is
NavMeshAgent.isOnNavMesh

Or immediately ask the mesh for the nearest valid point to your random
NavMesh.SamplePosition(...)

And of course try to build a route to critical points on the level. So that no one gets stuck.

Answer 2

Yes, you build a route to a point, it is either built or not.
