[Piltrafa]

Hello, I want to change this Scripts to vips get 50% extra rate.

local config = {
rate = 1.5, -- 4x More Experience
storage = 20012
}
local function endExpRate(cid)
if isPlayer(cid) == TRUE then
doPlayerSetRate(cid, SKILL__LEVEL, 1) -- config.lua rate
setPlayerStorageValue(cid, config.storage, -1)
doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_RED, "Your extra experience time has ended.")
end
end
function onLogin(cid)
local str = getPlayerStorageValue(cid, config.storage)
if(str >= 0 and (str - os.time()) > 0) then
doPlayerSetRate(cid, SKILL__LEVEL, config.rate)
doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE, "Your extra exp rate will expire at: " .. os.date("%X", str))
addEvent(endExpRate, (str - os.time()) * 1000, cid)
else
doPlayerSetRate(cid, SKILL__LEVEL, 1) -- config.lua rate
doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_RED, "You do not have any extra experience time.")
setPlayerStorageValue(cid, config.storage, -1)
end
return TRUE
end

It use base on storage value, but I want to chage if getPlayerVipDays(cid) >= 1 then and end when Vipdays its 0

Anyone knows?
