TFS 0.X varied damage depending on the direction the target is facing the attacker

[sabodden]

Would be possible in lua, maybe by using getCreatureLookDirection(target) to make the 'exori hur' more dynamic and skillable?
I would like to if target is backwards to the attacker: damage = damage * 2
And if target is beside to the attacker: damage = damage * 1.5
And one last if player is looking to the target direction damage = damage * 1

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)
setCombatParam(combat, COMBAT_PARAM_BLOCKARMOR, true)
setCombatParam(combat, COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_WEAPONTYPE)
setCombatParam(combat, COMBAT_PARAM_USECHARGES, true)

function onGetFormulaValues(cid, level, maglevel)
    min = ( (maglevel * 15) * 0.5 ) * -1
    max = ( (maglevel * 15) * 1.0 ) * -1
    return min, max
end
setCombatCallback(combat, CALLBACK_PARAM_LEVELMAGICVALUE, "onGetFormulaValues")

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

local targetDir = getCreatureLookDirection(getCreatureTarget(cid)) 
local cidDir = getCreatureLookDirection(cid)

if targetDir == cidDir then
damage = damage * 2
elseif (targetDir =~ cidDir) and not(lookFaceToFace) then
damage = damage * 1.5 
end

I am already little bussy, so i can't check when target and cid is face to face...
It is probalby 1 and 3 or 2 and 4, but i am nit sure.
