Solved Attempt to index itemType on NPC

[ralke]

Hi! I don't know what i'm doing wrong here. I already managed to add atributes to items from chests (onUse), and other NPCs too, but in this case, it doesn't let me add the roll atribute that comes from other system (oen's upgrade system). For this I tried:

local function addFocus(cid)
    choice[cid] = nil
    return true
end

local function releaseFocus(cid)
    choice[cid] = nil
    return true
end

local function creatureSayCallback(cid, type, msg)
    if not npcHandler:isFocused(cid) then
        return false
    end

    local player = Player(cid)
    local price_vortex = 500
    if msgcontains(msg, "vortice") or msgcontains(msg, "vortex") then
        npcHandler:say("Puedo hacer una varita de vortice. ¿Quieres comerciar?", cid)
        npcHandler.topic[cid] = 1
    elseif msgcontains(msg, "yes") or msgcontains(msg, "si") and npcHandler.topic[cid] == 1 then
        if player:removeMoney(price_vortex) then
            npcHandler:say("Aquí tienes.", cid)
            --player:addItem(6529, 6)
            local vortexItem = player:addItem(2190,1)
            vortexItem:setItemLevel(8, false)
            vortexItem:setRarity(COMMON)
            vortexItem:rollAttribute(player, itemType, weaponType, true)
        else
            npcHandler:say("No tienes suficiente dinero contigo.", cid)
        end
        npcHandler.topic[cid] = 0
    end
    return true
end

And for some reason, this line

vortexItem:rollAttribute(player, itemType, weaponType, true)

is returning me a nil value on itemType. Why is that happening? Tried to define itemType as local variable but couldn't make it work.



Thanks in advance!

Solved with

vortexItem:rollAttribute(player, vortexItem:getType(), vortexItem:getType():getWeaponType(), true)

Or commenting this from oen's system (I don't use upgradable or unique items, so, I think this line can be gone)

  if not itemType:isUpgradable() or self:isUnique() then
        return false
    end
