    Hi i’m trying to figure out, with no luck, how to set a group of 4 AI Units to follow the player as a group, there is some tutorials on youtube, but my problem is that my player is 3rd person character controlled by the user. How do i set the units as a group whitout selecting them ? And how do i make them as group follow the Player character?

    Also at first they will follow him as a disorganized group but in the future i intend to have them following the player in a formation, like shield wall or a triangle.

    Ok, the grouping and formation part is ok, now only the follow left, i’ve tried to put the MoveTo(Player) on the Update Method but the Units stand still recalculating the path every frame i guess.

    Thought it was ok, out of nowhere i started to receive the following message:

    NullReferenceException: Object reference not set to an instance of an object
    Apex.Units.TransientGroup`1[T].PrepareForAction () (at Assets/Apex/Apex Path/Scripts/Units/TransientGroup.cs:399)

    Current code:

    Ok, back again on track, it seems that Unity decided to call the Initialize of the script above before the Start of the PlayerUnit wich assing the unitFacade with GetUnitFacade();

    Now, only missing a way to follow the player.

    You are right calling MoveTo each frame will not work as the path finder is async and decoupled from steering and hence it is very likely that a path will never be returned in time to be used that frame.

    Please have a look at this post.
