Think World of Warcaft and Ragnarok: Healers get aggro (Threat) when they heal other players, and the tank (Warrioes usually) should have the largest threat built up so that bosses in raids stay focused on them and not the softer players like Warlocks, Mages, and most importantly the Priests.
change Stats-Priority on the units in the object editor, units with smaller numbers for priority will be attacked first and units with larger numbers for priority will be focused on last(if i'm understanding the question)
The "stats - Priority" field in the object editor is already a static threat system. But to create a dynamic system that increases or decreases like in WoW sounds like it would be pretty heavy on the processor.
I'm on a page about incorrect corrections, and spent the better part of like two hours trying to get someone to understand that -5^2 = -25, not 25, and then that post had comments get reposted because that group is self sustaining, and that person was in turn trying to explain what I just explained to them. And I'm taking that as a victory
I will be AFK for a couple of days you guys hold down the fort while I am gone. I will be checking in on my phone but that will severly limit me. Be back saturday!
