PvP Guard

[choweyiii]

I wanted to make a guard that would become aggressive towards a player attacking another player. So far, I have achieved this, however when going to attack a hostile creature the guards attack. I thought maybe I could do a race check, but that doesn't seem to be working. Here's what I've got so far:

local GUARD_FEATURE = "Enabled" 
local type, pairs = type, pairs;

function UberFireBall(pUnit, Player) 
    pUnit:FullCastSpellOnTarget(30971, Player)
end

function PvPGuard_OnSpawn(pUnit, Event)
	if (GUARD_FEATURE == "Enabled") then
        pUnit:RegisterEvent("Check_PvP", 1200, 0)
	end
	pUnit:EquipWeapons(1728, 1168, 11303)
	pUnit:SetFaction(1775)
end

function Check_PvP(pUnit, Event, Player)
    local Player_W = pUnit:GetInRangePlayers()
    
    if (Player_W ~= nil) and (type(Player_W) == "table") then
	
	for index, player in pairs(Player_W) do
	if (player:IsPlayerAttacking() == true) then
	pUnit:RegisterEvent("UberFireBall", 1500, 4)
	UberFireBall(pUnit, player)
	if  (player:GetPlayerRace() == 1 or --alliance
		player:GetPlayerRace() == 3 or
		player:GetPlayerRace() == 4 or
		player:GetPlayerRace() == 7 or
		player:GetPlayerRace() == 11) then
			pUnit:SetFaction(85) --Orgrimmar defender
			end
	if (player:GetPlayerRace() == 2 or --horde
		player:GetPlayerRace() == 5 or 
		player:GetPlayerRace() == 6 or
		player:GetPlayerRace() == 8 or
		player:GetPlayerRace() == 10) then
			if (player:IsPlayerAttacking(player:GetPlayerRace(1)) then --trying to do a race check here, because mobs don't have races(?) and would't attack you unless you are targeting a hostile race
			pUnit:SetFaction(12) --Orgrimmar defender
			pUnit:Despawn(10000, 200)
			
			end
		end
	end
	end 
	end
	end
	

function PvPGuard_OnCombat(pUnit, Event)
pUnit:SetAttackTimer(100, 100)
pUnit:CastSpell(43430)
end

function PvPGuard_OnLeaveCombat(pUnit, Event)
pUnit:Despawn(500, 1000)
pUnit:RemoveEvents()
end

RegisterUnitEvent(900056, 18, "PvPGuard_OnSpawn")
RegisterUnitEvent(900056, 2, "PvPGuard_OnLeaveCombat")
RegisterUnitEvent(900056, 1, "PvPGuard_OnCombat")

Table code taken from google. I just spiced it up a bit. (tinyurl.com/9xd27t9)


As always, I'll rep if you can help. Thanks!

"when going to attack a hostile creature the guards attack."

attack a creature (npc) - hostile or neutral ?
are the creatures of the same faction ?

No, they are hostile. I made the guard's faction the Shattrath City Guard's faction, they help you if a hostile enemy attacks you, such as hogger, but if you attack back they'll get you.
