    "SetDestination" can only be called on an active agent that has been placed on a NavMesh.

    If someone could help me...

    "gameC" object doesn't have an instance at the time when this error happens. Maybe you forgot to reference it in the inspector or you set it to null at some point?

    Either that or it doesn't have the "GameController" component on itself.

    It can be either one of these.
