Lua Area of Spell does not follow player

[.Smile]

I tried in several ways to make the area follow the player but it stays in the same place where the player used.

local combat = Combat()
combat:setParameter(COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)
combat:setParameter(COMBAT_PARAM_EFFECT, 5)
combat:setArea(createCombatArea(AREA_CIRCLE2X2))

function onGetFormulaValues(player, level, magicLevel)
    local min = (level / 5) + (magicLevel * 0.8) + 5
    local max = (level / 5) + (magicLevel * 2) + 12
    return -min, -max
end

combat:setCallback(CALLBACK_PARAM_LEVELMAGICVALUE, "onGetFormulaValues")

function onCastSpell(creature, variant)
    local position = creature:getPosition()
        Position({x = position.x + 3, y = position.y + 3, z = position.z}):sendMagicEffect(110)
        combat:execute(creature, variant)
    addEvent(function() 
        Position({x = position.x + 3, y = position.y + 3, z = position.z}):sendMagicEffect(110)
        combat:execute(creature, variant)
    end, 500)
    addEvent(function() 
        Position({x = position.x + 3, y = position.y + 3, z = position.z}):sendMagicEffect(110)
        combat:execute(creature, variant)
    end, 1000)
    addEvent(function() 
        Position({x = position.x + 3, y = position.y + 3, z = position.z}):sendMagicEffect(110)
        combat:execute(creature, variant)
    end, 1500)
    addEvent(function() 
        Position({x = position.x + 3, y = position.y + 3, z = position.z}):sendMagicEffect(110)
        combat:execute(creature, variant)
    end, 2000)
    return true
end
