TFS 1.X+ TFS 1.5 -- -Item count upgrade - as a charge on item

[tuduras]

Hello.
How to do item charge as upgrade like in photo:

I tried with AI to edit my upgrade system and otcv8/modules/game_interface/game_inferface.lua but with no results.
I need this. Has anyone ever done this?

PS: my upgrade system.lua

local config = {
    maxLevel = 12,
    upgradeItem = 2150,
    successChance = 100,    -- Szansa na sukces (%)
    dropLevelOnFail = true, -- Czy poziom ma spaść o 1 przy porażce? (true = tak, false = reset do 0)
    multiplierPerLevel = 1.05,
}

local action = Action()

function action.onUse(player, item, fromPosition, target, toPosition, isHotkey)
    if not target or not target:isItem() then
        return false
    end

    local it = target:getType()
    local name = it:getName()
    
    if it:getWeaponType() == WEAPON_NONE and it:getArmor() == 0 then
        player:sendTextMessage(MESSAGE_STATUS_SMALL, "Mozesz ulepszac tylko bron lub pancerze.")
        return true
    end

    local currentLevel = target:getCustomAttribute("upgradeLevel") or 0

    if currentLevel >= config.maxLevel then
        player:sendTextMessage(MESSAGE_STATUS_SMALL, "Ten przedmiot osiagnal juz maksymalny poziom.")
        return true
    end

    -- Usunięcie kryształu
    item:remove(1)

    if math.random(100) <= config.successChance then
        -- SUKCES: Poziom w górę
        local nextLevel = currentLevel + 1
        target:setCustomAttribute("upgradeLevel", nextLevel)
        
        local totalMultiplier = math.pow(config.multiplierPerLevel, nextLevel)
        
        -- Aktualizacja statystyk (w górę)
        if it:getAttack() > 0 then target:setAttribute(ITEM_ATTRIBUTE_ATTACK, math.floor(it:getAttack() * totalMultiplier)) end
        if it:getArmor() > 0 then target:setAttribute(ITEM_ATTRIBUTE_ARMOR, math.floor(it:getArmor() * totalMultiplier)) end
        if it:getDefense() > 0 then target:setAttribute(ITEM_ATTRIBUTE_DEFENSE, math.floor(it:getDefense() * totalMultiplier)) end

        target:setAttribute(ITEM_ATTRIBUTE_NAME, name .. " +" .. nextLevel)
        
        -- KLUCZOWA ZMIANA: Ustawiamy ładunki (charges) na poziom ulepszenia
        target:setAttribute(ITEM_ATTRIBUTE_CHARGES, nextLevel)

        player:sendTextMessage(MESSAGE_INFO_DESCR, "Sukces! Twoje " .. name .. " jest teraz na poziomie +" .. nextLevel .. ".")
        target:getPosition():sendMagicEffect(CONST_ME_MAGIC_GREEN)
    
    else
        -- PORAŻKA: "Spalenie" bonusu (cofnięcie poziomu)
        local penaltyLevel = 0
        if config.dropLevelOnFail then
            penaltyLevel = math.max(0, currentLevel - 1)
        end
        
        target:setCustomAttribute("upgradeLevel", penaltyLevel)
        
        local failMultiplier = math.pow(config.multiplierPerLevel, penaltyLevel)
        
        if it:getAttack() > 0 then target:setAttribute(ITEM_ATTRIBUTE_ATTACK, math.floor(it:getAttack() * failMultiplier)) end
        if it:getArmor() > 0 then target:setAttribute(ITEM_ATTRIBUTE_ARMOR, math.floor(it:getArmor() * failMultiplier)) end
        if it:getDefense() > 0 then target:setAttribute(ITEM_ATTRIBUTE_DEFENSE, math.floor(it:getDefense() * failMultiplier)) end

        if penaltyLevel > 0 then
            target:setAttribute(ITEM_ATTRIBUTE_NAME, name .. " +" .. penaltyLevel)
            -- Ustawiamy niższy poziom w ładunkach
            target:setAttribute(ITEM_ATTRIBUTE_CHARGES, penaltyLevel)
        else
            -- Pełny reset przedmiotu
            target:removeAttribute(ITEM_ATTRIBUTE_ATTACK)
            target:removeAttribute(ITEM_ATTRIBUTE_ARMOR)
            target:removeAttribute(ITEM_ATTRIBUTE_DEFENSE)
            target:removeAttribute(ITEM_ATTRIBUTE_NAME)
            target:removeAttribute(ITEM_ATTRIBUTE_CHARGES)
        end
        
        player:sendTextMessage(MESSAGE_STATUS_WARNING, "Porażka! Bonus zostal spalony. Przedmiot ma teraz poziom +" .. penaltyLevel .. ".")
        target:getPosition():sendMagicEffect(CONST_ME_POFF)
    end

    return true
end

action:id(config.upgradeItem)
action:register()

Of course best regards..
