stealthing npcs

[Jackhamme]

hey guys, I have been wounding how do you make a custom npc to stay in a stealth state and only leave it once the npc attacks the player. I have been into the AI agent secontion on my heidiSQL and gave that npc stealth, but he doesn't use it untill his next melee swing, its useless if he is in combat.

Any help?

Hey! It toke me some time to figure it out, but I made it :P. I wrote a little lua script for you (as I see you are using ArcEmu).
I tryed to use many spells that SHOULD make the npc go stealth but they didn't. So I solved the problem by morphing the npc into an invisible guy

local stealthguy =  npcId

function ourguy_OnSpawn(pUnit, event)
pUnit:SetModel(15435) -- Invisible guy DisplayId
end
function ourguy_OnCombat(pUnit, event)
pUnit:DeMorph() -- When someone comes throught combat range it'll morph back to the real DisplayId and attack.
end
function ourguy_OnLeaveCombat(pUnit, event)
if pUnit:IsAlive() == true then -- just to make sure it won't disappear after dying...
pUnit:SetModel(15435)
end
end
RegisterUnitEvent(stealthguy, 18, "ourguy_OnSpawn")
RegisterUnitEvent(stealthguy, 1, "ourguy_OnCombat")
RegisterUnitEvent(stealthguy, 2, "ourguy_OnLeaveCombat")

All you need to do is:

- Save this text into a .lua file (just name it to whatever you want)
- Place the .lua file into your scripts folder
- Change the RED part to the ID of your npc

If you've already given weapons for your NPC then tell me and I'll add a bonus line into the script (that's important because the NPC will be invisible but if it has weapon equipped that will be visible.
