attackType = ATTACK_PHYSICAL
needDirection = false
areaEffect = NM_ME_HIT_AREA
animationEffect = NM_ANI_NONE

hitEffect = NM_ME_HIT_AREA
damageEffect = NM_ME_HIT_AREA
animationColor = 86
offensive = true
drawblood = true

UltimateExplosionObject = MagicDamageObject(attackType, animationEffect, hitEffect, damageEffect, animationColor, offensive, drawblood, 0, 0)

function onCast(cid, creaturePos, level, maglv, var)
centerpos = {x=creaturePos.x, y=creaturePos.y, z=creaturePos.z}
n = tonumber(var)   -- try to convert it to a number
if n ~= nil then
    -- bugged
    -- ultimateExplosionObject.minDmg = var+0
    -- UltimateExplosionObject.maxDmg = var+0

    UltimateExplosionObject.minDmg = 0
    UltimateExplosionObject.maxDmg = 0
else
        -- UltimateExplosionObject.minDmg = (level * 2 + maglv * 3) * 5.3 - 30
        -- UltimateExplosionObject.maxDmg = (level * 2 + maglv * 3) * 7.0
    UltimateExplosionObject.minDmg = (level * 1.5 + maglv * 1.5) * 4.0
    UltimateExplosionObject.maxDmg = (level * 1.5 + maglv * 1.5) * 5.6
end

return doAreaMagic(cid, centerpos, needDirection, areaEffect, area, UltimateExplosionObject:ordered())
end

i want create the same on tfs 1.0 but when i create i have problems on more damage for magic level and level


here my spell:

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)
setCombatParam(combat, COMBAT_PARAM_BLOCKARMOR, 1)
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_HITAREA)
setCombatParam(combat, COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_WEAPONTYPE)
setCombatParam(combat, COMBAT_PARAM_USECHARGES, 1)

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

function onGetFormulaValues(cid, skill, maglv, factor)
    local skillTotal, levelTotal = skill * maglv, getPlayerLevel(cid) / 5
    return -(((skillTotal * 0.02) + 4) + (levelTotal)), -(((skillTotal * 0.04) + 9) + (levelTotal))
end

setCombatCallback(combat, CALLBACK_PARAM_SKILLVALUE, "onGetFormulaValues")

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