I’ve used nav mesh agents without any problems before but it just keeps repeating this error now and I’ve already been checking the same things 10 times over.

  • The agent is on a nav mesh (above it)
  • I already baked the nav mesh, the plane is static and the blue indication is showing
  • agent is set to humanoid
  • Also tried putting the agent a little bit higher or a lot higher but with the same result.
"GetRemainingDistance" can only be called on an active agent that has been placed on a NavMesh.

What else is there left to check?

Do you know there’s a dedicated Navigation forum? I’ll move your post there for you.

Alright thanks

The most likely sources of this error are:

  • you are trying to tell the prefab where to go. You need to tell the Instantiate()-ed thing where to go. Instantiate() returns a reference to the thing you instantiated

  • you are telling a disable navmesh agent to go somewhere. This won’t work.

Mh I tested some values in the terminal and it prints

navMeshAgent.isOnNavMesh
false
navMeshAgent.isActiveAndEnabled
false
navMeshAgent.isPathStale
false
navMeshAgent.isStopped
false

navMeshAgent
{Nolan (UnityEngine.NavMeshAgent)}

navMeshAgent.gameObject.scene.name
gameObject.scene.name

Ah nevermind the nav mesh agent is being disabled by something on runtime, I bought some asset and followed along with the instructions but it seems like something went very wrong.
