    Hi,

    I have an agent and I move it manually while reading the .desiredVelocity to figure out the movement.

    But before setting .destination, I have to hide my navmesh link if I don't want a particular character to use that link. Is this the right way since Auto Traverse Off Mesh Link being unchecked does absolutely NOTHING for manual agent even though I am reading .desiredVelocity - the agent clearly ignores this checkbox in this circumstance.

    All I can do is hide the link before I set the destination - a huge hack?

    Yes the 'autoTraverseOffMeshLink' controls the movement behaviour over the link (automatic or not) - it does not decide whether the link is accessible to pathfinding.

    • One way is to disable the link before setting the destination, then enabling it - when the path is found.
    • Another way is to use a specific area-type for the link - then set the agents area mask to exclude that of the link.

    Maybe it's kind of the same issue/solution, but here is my case:
    - Many closed doors (NavMeshLink) - More than 29...
    - Many agents with different door keys
    - Many agents without any key

    What would be the best solution to achieve that?

    It seems to be a bad idea to enable/disable every NavMeshLink before setting each destination of each agent, isn't it?
