TFS 1.X+ The use of the Spell consumes more mana according to the player's level.

[Piifafa]

I would like to know how I can increase the mana consumption of certain spells according to the player's level. I can't think of any easy alternative for this.

I would like it to be like the example, after level 200, the use of the magic increases its mana cost according to a rule or something similar, every 10 levels or a small percentage for each level gained.

    local base = 250
    local variation = 50
    
    local formula = 3.0 * maglevel + (2 * level)
    
    local min = (formula * (base - variation)) / 100
    local max = (formula * (base + variation)) / 100
    return -min, -max
end

function onCastSpell(creature, variant)
    return combat:execute(creature, variant)
end

local config = {
    manaLevel = 200, -- Additional mana will be consumed every 10 levels after this level
    manaIncrease = 100, -- How much more mana the spell requires for every 10 levels
    defaultMana = 800, -- How much mana the spell normally needs (in spells.xml)
}

local combat = Combat()
combat:setParameter(COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)

combat:setParameter(COMBAT_PARAM_BLOCKSHIELD, 1)

combat:setArea(createCombatArea(AREA_CIRCLE5X5))

function onGetFormulaValues(player, level, maglevel)
    local base = 250
    local variation = 50
  
    local formula = 3.0 * maglevel + (2 * level)
  
    local min = (formula * (base - variation)) / 100
    local max = (formula * (base + variation)) / 100

function onCastSpell(creature, variant)
    local playerLevel = creature:getLevel()
    if playerLevel >= config.manaLevel then
        local removeMana = math.floor((playerLevel - config.manaLevel) / 10) * config.manaIncrease
        if creature:getMana() < (removeMana + config.defaultMana) then
            creature:sendCancelMessage(RETURNVALUE_NOTENOUGHMANA)
            return false
        end
        creature:addMana(-removeMana)
    end
    return combat:execute(creature, variant)

I ended up doing it a different way but following your logic!

local combat = Combat()
combat:setParameter(COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)
combat:setParameter(COMBAT_PARAM_BLOCKARMOR, 1)
combat:setParameter(COMBAT_PARAM_BLOCKSHIELD, 1)
combat:setParameter(COMBAT_PARAM_EFFECT, CONST_ME_EXPLOSIONAREA)
combat:setArea(createCombatArea(AREA_CIRCLE5X5))

function onGetFormulaValues(player, level, maglevel)
    local base = 250
    local variation = 50
    
    local formula = 3.0 * maglevel + (2 * level)
    
    local min = (formula * (base - variation)) / 100
    local max = (formula * (base + variation)) / 100
    return -min, -max
end

combat:setCallback(CALLBACK_PARAM_LEVELMAGICVALUE, "onGetFormulaValues")

function onCastSpell(creature, variant)
    local player = Player(creature)
    if player then
        -- Se o jogador estiver acima do nível 200, aplica o custo de mana
        if player:getLevel() > 200 then
            local manaCost = 5 + (player:getLevel() - 200) * 5 -- 5 é o custo adicional de mana para cada 10 níveis após 200
            -- Verifica se o jogador tem mana suficiente para lançar a magia
            if player:getMana() >= manaCost then
                player:addMana(-manaCost) -- Reduz a mana do jogador pelo custo da magia
                return combat:execute(creature, variant) -- Executa a magia
            end
        else
            return combat:execute(creature, variant) -- Executa a magia sem custo de mana para jogadores até o nível 200
        end
    end
    
    return false
end

its funny because if you put it to spent some % of mana, it will increase by level too...
