Lua Get players in area and compare (operating cost) HELP

[LucasFerraz]

Hi, im doing a Capture the Flag Event and I just have to finish the last function (Getwinners).
Can someone tell me the best way to check it? I'm thinking about operating cost.

function ctfcheckwinnerteam(cid)

	for _, pid in ipairs(getPlayersOnline()) do 
			if pid ~= cid and isInRange(getCreaturePosition(pid), ctfconfig.frompos, ctfconfig.topos) then
				if getGlobalStorageValue(ctfredGoal) < getGlobalStorageValue(ctfblueGoal) then
					doTeleportThing(cid, getTownTemplePosition(getPlayerTown(cid)))
					doRemoveCondition(cid, CONDITION_INFIGHT)
					if getPlayerStorageValue(cid, ctfplayerblueteam) == 1 then
						doPlayerAddItem(cid, ctfmedal, 1)
						doPlayerAddItem(cid, ctfreward, ctfrewardcount)
						doAddEventPoints(cid, 1)
					end
					doSavePlayerAndHouse(cid)
				elseif getGlobalStorageValue(ctfredGoal) > getGlobalStorageValue(ctfblueGoal) then
					doTeleportThing(cid, getTownTemplePosition(getPlayerTown(cid)))
					doRemoveCondition(cid, CONDITION_INFIGHT)
					if getPlayerStorageValue(cid, ctfplayerredteam) == 1 then
						doPlayerAddItem(cid, ctfmedal, 1)
						doPlayerAddItem(cid, ctfreward, ctfrewardcount)
						doAddEventPoints(cid, 1)
					end
					doSavePlayerAndHouse(cid)
				elseif getGlobalStorageValue(ctfredGoal) == getGlobalStorageValue(ctfblueGoal) then
					doTeleportThing(cid, getTownTemplePosition(getPlayerTown(cid)))
					doRemoveCondition(cid, CONDITION_INFIGHT)
					doSavePlayerAndHouse(cid)
				end
			end
	end

	if getGlobalStorageValue(ctfredGoal) < getGlobalStorageValue(ctfblueGoal) then
		broadcastMessage("The Blue Team won in Capture the Flag\'s Camp today!", MESSAGE_EVENT_ADVANCE)
	elseif getGlobalStorageValue(ctfredGoal) > getGlobalStorageValue(ctfblueGoal) then
		broadcastMessage("The Red Team won in Capture the Flag\'s Camp today!", MESSAGE_EVENT_ADVANCE)
	elseif getGlobalStorageValue(ctfredGoal) == getGlobalStorageValue(ctfblueGoal) then
		broadcastMessage("No winners in Capture the Flag\'s Camp today!", MESSAGE_EVENT_ADVANCE)
	end

	addEvent(ctfremovetp(cid), 1 * 1000, cid)
	addEvent(ctfremovestorages(cid), 2 * 1000, cid)
end
