Lua TFS 1.3 Spell with direction condition and position effect

[Icaraii]

Hello guys, I'm doing some custom spells with sprites 96x64 and I would like a little hlep with two things.

1: How do I make the spell show effects with those variations: if player facing north or south effect x, if player facing left or right effect y.

2: As my sprites are bigger than 32x32, I need to set them in place by x,y,z, however I don't know how to set that up. I would like for when player is facing north, effect will be set a specific x,y,z. If player is facing south, effect will be set to another specific x,y,z. If player is facing left, effect will be set to another specific x,y,z. If player is facing right, effect will be set to another specific x,y,z.

Now I will put all the ways I tried to do this script and I will be glad if anyone can help me with it.

Try one:

local combat = Combat()
combat:setParameter(COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)
combat:setParameter(COMBAT_PARAM_BLOCKARMOR, false)
combat:setParameter(COMBAT_PARAM_USECHARGES, true)

local area = createCombatArea( {
{1, 1, 1},
{0, 3, 0},
{0, 0, 0} } )
setCombatArea(combat, area)

function onGetFormulaValues(player, skill, attack, skill, factor)

    local maxHealth = player:getMaxHealth()
    local maxMana = player:getMaxMana()
    local playlvl = player:getLevel()

    if (playlvl<300) then
    local min = ((player:getLevel()) + ((maxHealth + maxMana) / 16) + (attack * 4) + (skill * 2)) * 0,5
    local max = ((player:getLevel()) + ((maxHealth + maxMana) / 16) + (attack * 4) + (skill * 2)) * 1,0
    return -min, -max
    
    else
    local min = ((300) + ((maxHealth + maxMana) / 16) + (attack * 4) + (skill * 2)) * 0,5
    local max = ((300) + ((maxHealth + maxMana) / 16) + (attack * 4) + (skill * 2)) * 1,0
    return -min, -max
    end   
end
combat:setCallback(CALLBACK_PARAM_SKILLVALUE, "onGetFormulaValues")

function onCastSpell(creature, variant, cid)
local parameters = { cid = cid, var = var}
local position = {x=getThingPos(getCreatureTarget(cid)).x+1, y=getThingPos(getCreatureTarget(cid)).y+1, z=getThingPos(getCreatureTarget(cid)).z}
doSendMagicEffect(position, 99)

local position = {x=getPlayerPosition(cid).x+1, y=getPlayerPosition(cid).y+1, z=getPlayerPosition(cid).z}
    return combat:execute(creature, variant, cid)
end
