If I may, I too have a question regarding Henchmen. If I wanted an NPC to follow the PC after a conversation, how do I do that?
The script SithRevan posted doesn't specify an NPC, because it has to be linked to the On_Heartbeat of the NPC. But this will make him follow as soon as the PC enters the module.
Also, with that script, the NPC doesn't attack. How do I make him attack whenever the PC attacks?
