Lua Soul spend on cast rune if player have storage

[LeOnArd0]

Sup guys.

I have a question (TFS 1.5)

My idea is that the player who had a storage 15550, 1, spend 1 soul to cast any rune. If he has 15500, 0, he will not spend soul when casting the rune. I thought it better to add it directly to the function, right?

I'm having trouble fitting the rule and ensuring that if the player with storage 15550, 1 doesn't have > 1 soul, the rune is not conjured.

I tried some methods but it didn't work.

Original code:

function Player:conjureItem(reagentId, conjureId, conjureCount, effect)
    if not conjureCount and conjureId ~= 0 then
        local itemType = ItemType(conjureId)
        if itemType:getId() == 0 then
            return false
        end

        local charges = itemType:getCharges()
        if charges ~= 0 then
            conjureCount = charges
        end
    end

    if reagentId ~= 0 then
        local left = self:getSlotItem(CONST_SLOT_LEFT)
        local right = self:getSlotItem(CONST_SLOT_RIGHT)

        local canConjure = false

        if left and left:getId() == reagentId then
            left:transform(conjureId, conjureCount)
            canConjure = true
        end

        if right and right:getId() == reagentId then
            right:transform(conjureId, conjureCount)
            canConjure = true
        end

        if not canConjure then
            self:sendCancelMessage(RETURNVALUE_YOUNEEDAMAGICITEMTOCASTSPELL)
            self:getPosition():sendMagicEffect(CONST_ME_POFF)
            return false
        end
       
    else
        local item = self:addItem(conjureId, conjureCount)
        if not item then
            self:sendCancelMessage(RETURNVALUE_NOTPOSSIBLE)
            self:getPosition():sendMagicEffect(CONST_ME_POFF)
            return false
        end
    end
   
    self:getPosition():sendMagicEffect(effect and effect or CONST_ME_MAGIC_RED)
    return true
end

Hi,

if you are using Player object in the context of itself, like inside of the Player:here_function_name, then you need to use the keyword: self.

like this:

self:getStorageValue(15550)

etc.
