Lua Fire Damage Condition

[zetto]

Hello, I'm trying to do a fire damage that decreases with time, for example the firsts 10hits will be lost 10hp, in the next 10hits will be lost 5hp...
But I'm don't know how do it, someone can help me?
Thanks!

I'm using it:

local condition = createConditionObject(CONDITION_FIRE)
setConditionParam(condition, CONDITION_PARAM_DELAYED, 1)
addDamageCondition(condition, 10, 4000, -5)

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TARGETCASTERORTOPMOST, true)
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_FIREDAMAGE)
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_HITBYFIRE)
setCombatParam(combat, COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_FIRE)

local condition = createConditionObject(CONDITION_FIRE)
setConditionParam(condition, CONDITION_PARAM_DELAYED, 1)
addDamageCondition(condition, 10, 2000, -10)
setCombatCondition(combat, condition)

function onCastSpell(cid, var)
return doCombat(cid, combat, var)
end
