Lua NPC that attack skulleds

[brunolopes]

Hello,

I am having problem with a script I made.

local config = {
	maxDistance = 20,
	followTimeout = 10,
	range = 5,
	damage = {min = 500, max = 1000},
	messages = {
		onSpot = "We do not tolerate people like you, %s",
		onFlee = "I will catch you next time!",
		onTimeout = "You got me this time, but just wait, %s!",
		onClean = "Now behave in the future"
	}
}

local behavior = {target = {now = 0, last = 0}, position = 0, attack = 0}

function resetNpcBehavior()
	behavior.target.now = 0
	behavior.attack = 0
	selfFollow(0)
	doTeleportThing(getNpcId(), behavior.position)
end

function updateNpcBehavior()
	if not isCreature(behavior.target.now) then
		resetNpcBehavior()
	elseif getCreatureSkull(behavior.target.now) < 3 then
		selfSay(config.messages.onClean)
		resetNpcBehavior()
	end
	
	if behavior.target.now == 0 then
		local creatures = getSpectators(getNpcPos(), config.range, config.range, false)
		for i = 1, #creatures do
			local target = creatures[i]
			if target ~= 0 then
				if isCreature(target) and getCreatureSkull(target) >= 3 then
					if not getTilePzInfo(getCreaturePosition(target)) then
						if selfFollow(target) then
							behavior.target.now = target
							if target ~= behavior.target.last then
								selfSay(config.messages.onSpot:format(getCreatureName(target)))
							end
							behavior.target.last = target
						end
					end
				end
			end
		end
	end
end

function onCreatureAppear(cid)
	if cid == getNpcId() then
		behavior[getNpcId()] = {target = {now = 0, last = 0}, attack = 0, position = 0}
		behavior.position = getNpcPos()
	end
end

function onCreatureDisappear(cid)
	if(cid == target) then
		resetNpcBehavior()
	end
end

function onThink()
	updateNpcBehavior()

	local target = behavior.target.now
	
	if target == 0 then
		return true
	end

	if getCreaturePosition(target).z ~= getNpcPos().z then
		resetNpcBehavior()
		return true
	end

	if getNpcDistanceTo(target) > config.maxDistance then
		selfSay(config.messages.onFlee)
		resetNpcBehavior()
		return true
	end

	if behavior.attack == 0 then
		behavior.attack = os.clock()
	end

	if os.clock() - behavior.attack > config.followTimeout then
		selfSay(config.messages.onTimeout:format(getCreatureName(target)))
		resetNpcBehavior()
		return true
	end

	if getNpcDistanceTo(target) <= 1 then
		doTargetCombatHealth(getNpcCid(), target, COMBAT_LIFEDRAIN, -config.damage.min, -config.damage.max, CONST_ME_BLOCKHIT)
		behavior.attack = os.clock()
	end
end

The problem is simple: I summon two or more NPCs, if one spots a skulled creature the other two teleports to the one that spotted the creature.
