Using Navmesh Building Components Errors

[redsam121]

I'm trying to integrate the navmesh components such as navmesh surface, to allow more dynamic movement for AI (e.g. walk onto platforms), but I've run into a number of problems.

1. There is a delay for when the AI recalculates paths.
   
2. The Navmeshagent ignores the navmesh surface boundaries and walks off the edge.

Can someone help me solve these problems, so I can create a new integration.

This is an example of what I'm trying to accomplish for the AI movement.

I have made a prototype for the jump mechanics so that the AI is compatible with NavmeshLink. Though still haven't solved the first two problems.

public virtual bool isOnJumpLink
       {
           get
           {
               if (!useNavMeshAgent) return false;
               if (navMeshAgent.isOnOffMeshLink && navMeshAgent.currentOffMeshLinkData.linkType == UnityEngine.AI.OffMeshLinkType.LinkTypeJumpAcross) return true;
               var linkData = navMeshAgent.currentOffMeshLinkData.offMeshLink;
               if (linkData != null)
               {
                   if (linkData.area == UnityEngine.AI.NavMesh.GetAreaFromName("Jump"))
                   {
                       return true;
                   }
               }
               if (navMeshAgent.navMeshOwner is NavMeshLink)
               {
                   var linkData2 = (NavMeshLink)navMeshAgent.navMeshOwner;
                   if (linkData2.area == UnityEngine.AI.NavMesh.GetAreaFromName("Jump"))
                   {
                       return true;
                   }
               }
               return false;
           }
       }

I solved the second problem by increasing the stopping distance, so now I only have the recalculate path problem left.

[redsam121]

I have create a prototype code for recalculating paths when current is only partial. When a new path is available it will update the current path.


           //If path is incomplete find a new path
           if (navMeshAgent.path.status == NavMeshPathStatus.PathPartial)
           {
               NavMeshPath newPath = new NavMeshPath();
               navMeshAgent.CalculatePath(_destination, newPath);
               Debug.Log(newPath.corners[newPath.corners.Length - 1] != navMeshAgent.destination);
               //Only update path when a new closest destination is available
               if (newPath.corners[newPath.corners.Length - 1] != navMeshAgent.destination)
               {
                   navMeshAgent.ResetPath();
               }
           }
