Lua is there a way to stop a loop if the player is no longer online?

[Lurk]

I have this script that works in a loop, but if the player is kiked at the 7th loop for example, I'll still receive like 13 errors in the console telling me that the player couldn't be found. Is there a if getPlayer == false then break ?

script:

local config = {
toKnow = 123456,
storage = 789456,
pos = {x = 160, y = 54, z = 7}, -- para onde o jogador será teleportado caso o tempo tenha acabado.
}

local count = 21

function onKill(cid, target, lastHit)
for i= 0, count-1 do
    if getPlayerStorageValue(cid, config.toKnow+i) == 1 then
        if getPlayerStorageValue(cid, config.storage+i) < os.time () then
            doSendMagicEffect(getThingPos(cid), CONST_ME_TELEPORT)
            doRemoveCreature(cid)
        end
    end
end
return true
end


local count2 = 21

function onLogin(cid)
for i= 0, count2-1 do
    if getPlayerStorageValue(cid, config.toKnow+i) == 1 then
        if getPlayerStorageValue(cid, config.storage+i)  < os.time () then
            doTeleportThing(cid, config.pos)
            setPlayerStorageValue(cid, config.toKnow+i, 0)
        end
    end
end
return true
end

console error
