    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.

    Code (CSharp):
    1. "GetRemainingDistance" can only be called on an active agent that has been placed on a NavMesh.
    2. UnityEngine.StackTraceUtility:ExtractStackTrace ()
    3. BehaviorDesigner.Runtime.Tasks.Movement.NavMeshMovement:HasArrived () (at Assets/Behavior Designer Movement/Scripts/Tasks/NavMeshMovement.cs:104)
    4. Opsive.DeathmatchAIKit.AI.Actions.SearchForTarget:OnUpdate () (at Assets/Opsive/DeathmatchAIKit/Scripts/AI/Actions/Attack/SearchForTarget.cs:97)
    5. BehaviorDesigner.Runtime.BehaviorManager:RunTask (BehaviorDesigner.Runtime.BehaviorManager/BehaviorTree,int,int,BehaviorDesigner.Runtime.Tasks.TaskStatus)
    6. BehaviorDesigner.Runtime.BehaviorManager:Tick (BehaviorDesigner.Runtime.BehaviorManager/BehaviorTree)
    7. BehaviorDesigner.Runtime.BehaviorManager:Tick ()
    8. BehaviorDesigner.Runtime.BehaviorManager:Update ()
    What else is there left to check?

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

    The most likely sources of this error are:

    - you are trying to tell the prefab where to go. You need to tell the Instantiate<T>()-ed thing where to go. Instantiate<T>() 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

    Code (CSharp):
    1. navMeshAgent.isOnNavMesh
    2. false
    3. navMeshAgent.isActiveAndEnabled
    4. false
    5. navMeshAgent.isPathStale
    6. false
    7. navMeshAgent.isStopped
    8. false
    9.  
    10. navMeshAgent
    11. {Nolan (UnityEngine.NavMeshAgent)}
    12.  
    13. navMeshAgent.gameObject.scene.name
    14. 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.
