Detecting if a target is off the navmesh?

Hello,
How can I detect if a target is off the Navmesh using an if statement? Thank you.

 

You could try something along those lines...

Code (CSharp):

1. NavMeshPath navpath = new NavMeshPath();
2.  
3. NavMesh.CalculatePath (somePosition, someOtherPosition, -1, navpath);
4.  
5. if (navpath.status == NavMeshPathStatus.PathPartial || navpath.status == NavMeshPathStatus.PathInvalid) {
6.     // Not reachable
7. }

 

You could use NavMesh.SamplePosition which returns false if point not on navmesh.
