Lua TSF 1.3 How to: Spell only cast if player is using item x

[Icaraii]

Hello guys,

I would like to edit some spells in my server so it only be casted if player is using some specific item, for example:

Player can only cast exori if player is using sword id 1111, sword id 2222, axe 1111 or axe id 2222. If player ain't using one of these itens appear message "you can't use this spell"

And, what if I would like for the player to be using 2 itens at the same time? For example:

Sword 1111, sword id 2222, axe 1111 or axe id 2222 in weapon hand and shield 1111, shield 2222 or shield 3333 in shield hand?

I will be glad if someone can help me

I think you are looking for this one

TFS 1.X+ - Check if item is equiped on player to cast spells

Hi I'm trying to put a function to check if the player is using an item, if it is positive, the player can use the ability, otherwise the player can't use the spell, since only players with the equipped item can release the spell. local weapons = { {itemId = 2321}, -- giant smithhammer...

It kinda is. I tested and it's part of what I need, and works perfectly. But I would also like to know how to check 2 itens, for example:

Sword 1111, sword id 2222, axe 1111 or axe id 2222 in weapon hand and shield 1111, shield 2222 or shield 3333 in shield hand, if player has one of those sword and also one of those shield equiped, he can use the spell. If has only one of them, he can't use the spell.

would it be something like this?

function onCastSpell(creature, var)
    local weapons = {
        1111,
    }

    for slot = CONST_SLOT_LEFT do
        local playerWeapon = creature:getSlotItem(slot)
        if playerWeapon and table.contains(weapons, playerWeapon:getId()) then
            return combat:execute(creature, var)
        end
    local shields = {
        1111,
    }

    for slot = CONST_SLOT_RIGHT do
        local playerShield = creature:getSlotItem(slot)
        if playerShield and table.contains(shields, playerShield:getId()) then
            return combat:execute(creature, var)
        end
    end

    creature:sendTextMessage(MESSAGE_STATUS_SMALL, "You need a special weapon to cast this spell.")
    return false
end

Might not be the best way and requiers weapon to be in left hand and shield in right hand but works okay xD

local combat = Combat()
combat:setParameter(COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)
combat:setParameter(COMBAT_PARAM_EFFECT, CONST_ME_HITAREA)
combat:setParameter(COMBAT_PARAM_BLOCKARMOR, 1)
combat:setParameter(COMBAT_PARAM_USECHARGES, 1)
combat:setArea(createCombatArea(AREA_SQUARE1X1))

function onGetFormulaValues(player, skill, attack, factor)
    local level = player:getLevel()
    local min = (level / 5) + (skill + attack) * 0.5
    local max = (level / 5) + (skill + attack) * 1.5
    return -min * 1.1, -max * 1.1 -- TODO : Use New Real Formula instead of an %
end

combat:setCallback(CALLBACK_PARAM_SKILLVALUE, "onGetFormulaValues")
function onCastSpell(creature, var)
    local weapons = {2321, 5342}
    local shields = {6391, 2523}

        local slotWeapon = CONST_SLOT_LEFT
        local slotShield = CONST_SLOT_RIGHT
        
        local playerWeapon = creature:getSlotItem(slotWeapon)
        local playerShield = creature:getSlotItem(slotShield)
        if playerWeapon and table.contains(weapons, playerWeapon:getId()) then
        if playerShield and table.contains(shields, playerShield:getId()) then
            return combat:execute(creature, var)
        end
    end

    creature:sendTextMessage(MESSAGE_STATUS_SMALL, "You need a special weapon to cast this spell.")
    return false
