Just collecting info here. Has anyone ever been able to get NPCs to move in formation? Say two abreast and five deep, for example. If so, how?
Not as far as I know. Using hearbeat scripts it might be possible. It would involve some pretty complicated scripts which store the PC coordinates and then compare that to the previous PC coordinates and also the NPC coordinates. Then it instructs the NPC to walk to the coordinates which have been extrapolated. During combat they would have to abandon formation unless they have ranged weapons only. If they had melee weapons they would probably just jitter on the spot. Most follower NPCs already have heartbeat scripts so it would interfere with the main game. I don't think it's worth the bother and believe me it would be a lot of bother.
