Additional spell exhaust

[Erexo]

Hello,
Im looking for additional exhaust for every spell (for combo system).
ex; Spell have exhaust=2000, and exhaust2=5000, that means if you use that spell, you can use it again after 5 seconds, but you can use any other offensive spell after 2 seconds.
I was thinking how, but I dont know. Someone could help ?
Greetings. TFS 0.4

It's very simple, example code for berserk.lua spell.
Normal spell:

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_HITAREA)
setCombatParam(combat, COMBAT_PARAM_USECHARGES, true)

local area = createCombatArea(AREA_SQUARE1X1)
setCombatArea(combat, area)

function onGetFormulaValues(cid, level, skill, attack, factor)
    local skillTotal, levelTotal = skill + attack, level / 5
    return -(skillTotal * 0.5 + levelTotal), -(skillTotal * 1.5 + levelTotal)
end

setCombatCallback(combat, CALLBACK_PARAM_SKILLVALUE, "onGetFormulaValues")
function onCastSpell(cid, var)
    return doCombat(cid, combat, var)
end

Spell with 5 seconds exhaust for that spell, but just 2 seconds for other spells:

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_HITAREA)
setCombatParam(combat, COMBAT_PARAM_USECHARGES, true)

local area = createCombatArea(AREA_SQUARE1X1)
setCombatArea(combat, area)

function onGetFormulaValues(cid, level, skill, attack, factor)
    local skillTotal, levelTotal = skill + attack, level / 5
    return -(skillTotal * 0.5 + levelTotal), -(skillTotal * 1.5 + levelTotal)
end

setCombatCallback(combat, CALLBACK_PARAM_SKILLVALUE, "onGetFormulaValues")

local spellStorageID = 65300
function onCastSpell(cid, var)
    if(exhaustion.check(cid, spellStorageID)) then
        doPlayerSendCancel(cid, "You can use one spell only once per 5 seconds.")
        return false
    end
    return doCombat(cid, combat, var) and (exhaustion.set(cid, spellStorageID, 5) or true)
end

With description what and why is changed:

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_HITAREA)
setCombatParam(combat, COMBAT_PARAM_USECHARGES, true)

local area = createCombatArea(AREA_SQUARE1X1)
setCombatArea(combat, area)

function onGetFormulaValues(cid, level, skill, attack, factor)
    local skillTotal, levelTotal = skill + attack, level / 5
    return -(skillTotal * 0.5 + levelTotal), -(skillTotal * 1.5 + levelTotal)
end

setCombatCallback(combat, CALLBACK_PARAM_SKILLVALUE, "onGetFormulaValues")

-- add line with definition of storageID to keep exhaust, OTHER for every spell
-- if you add same ID in 2 spells that will block each other
-- (can be useful to block some spell combinations!)
local spellStorageID = 65300
-- maximum value was [in 0.3.6] '65515',
-- so you can use 65300 - 65515 [lower values can be used by other scripts/quests]

function onCastSpell(cid, var)
    -- under 'onCastSpell(cid, var)' add these 4 lines --
    if(exhaustion.check(cid, spellStorageID)) then -- is exhausted
        doPlayerSendCancel(cid, "You can use one spell only once per 5 seconds.")
        return false -- return false makes it does not remove player mana/rune
    end
    -- end --
   
    -- replace 'return doCombat(cid, combat, var)' with:
    return doCombat(cid, combat, var) and (exhaustion.set(cid, spellStorageID, 5) or true)
    -- we add here ' and (exhaustion.set(cid, spellStorageID, 5) or true)',
    -- because we want it add 5 seconds exhaust ONLY if player can execute spell
    -- ex. if target is behind wall 'doCombat' will 'return false'
    -- and at end is 'or true' because we must make it return 'true' to make spell remove mana/rune
end

Thank you for your respond.
I was thinking of that, but I didnt know that return false also cancel cooldowns.
