How spell know where to deal damage ?

[BulawOw]

local combat = Combat()
combat:setParameter(COMBAT_PARAM_TYPE, COMBAT_ENERGYDAMAGE)
combat:setParameter(COMBAT_PARAM_EFFECT, CONST_ME_ENERGYAREA)
combat:setArea(createCombatArea(AREA_BEAM8))

function onGetFormulaValues(player, level, magicLevel)
    local min = (level / 5) + (magicLevel * 3.6) + 22
    local max = (level / 5) + (magicLevel * 6) + 37
    return -min, -max
end

combat:setCallback(CALLBACK_PARAM_LEVELMAGICVALUE, "onGetFormulaValues")

function onCastSpell(creature, variant)
    return combat:execute(creature, variant)
end

I believe it's in spells.xml, I think it's direction="1" or something

<instant group="attack" spellid="23" name="Great Energy Beam" words="exevo gran vis lux" level="29" mana="110" direction="1" cooldown="6000" groupcooldown="2000" needlearn="0" script="attack/great_energy_beam.lua">
        <vocation name="Sorcerer" />
        <vocation name="Master Sorcerer" />
    </instant>

Ok got it so if its 1 then its gonna return the dmg the way player is looking but if its 0 its just gonna cast it like it is set up in script right ?

I think you can just remove it
