What's wrong here?

[choweyiii]

I wanted to make a mob that shoots, but if something comes into melee range of the archer it runs back a fews steps to prepare to shoot, so I came up with this idea to fix it, but my syntax is wrong. The error I get is: "attempt to compare number with nil". I will give rep where rep is deserved.

function OrgrimmarGuard_Shoot(Unit, Event)
   Unit:GetMainTank() Unit:GetDistanceYards() if distance >=5 then
   Unit:FullCastSpellOnTarget(69710) --150% Shoot 5-30 yard range
   end
end

Your code appears to be cunfuzzled.

function OrgrimmarGuard_Shoot(Unit, Event)
local plr = Unit:GetMainTank()
if Unit:GetDistanceYards(plr) >= 5 then
Unit:FullCastSpellOnTarget(69710, plr)
end
end

And you do realise ArcEmu already supports ranged attacks? Go into creature_proto table, change can_ranged column to 1 and change min_rangedamage and max_rangedamage values. Give him a bow (.npc equip3 itemid) and there you have it, your personal shooting npc (the shooting animation doesn't have projectiles for some reason).

That didn't work for me the npc still runs off to recast shoot; projectiles are shown with Shoot spell 69710

[stoneharry]

function OrgrimmarGuard_Shoot(Unit, Event)
	if Unit:GetDistanceYards(Unit:GetMainTank()) >4 then
		Unit:FullCastSpellOnTarget(69710, Unit:GetMainTank())
		end
end

GetDistanceYards does have parameters, you get the distance in yards between two objects. Player and creature in your case.

You're probably just getting warnings of unhandled spell effects or w/e.
