   Hi,
   I would like to know if my NavAgent is going on a not accessible NavMesh area (because there is no continuity of NavMesh) but it is walkable.
   
   
   
   

   Code (csharp):

   1.  
   2.     if(MouseClickOnWalkable && AreaIsAccessible){
   3.  
   4.     MyNavAgent.SetDestination(ThisTargetPosition);
   5.     ......
   6.  

   No problem for "MouseClickOnWalkable" bool but I need to know also "AreaIsAccessible" bool.
   
   
   Otherwise the character moves up to approach the target point. I wish that when I click on a not accessible area, it does not move.
   How you do?

   NavMesh.CalculatePath does not work.
   Even if the target point is located in a "detached area" of NavMesh, the result of CalculatePath is true!
   Why??

   Maybe you should also check if the path is complete or not, since CalculatePath still return true for partial path

   //Check if path is continuous to destination
   if (agentNav.pathStatus == NavMeshPathStatus.PathPartial)
   {
   //etc...
   }
