Well I've been redoing a lot of my spells this way, honestly idk why, easier to use i suppose. WARNING: if you plan to use this spell file format, it does not work with bonuses such as utito tempo, or equipment bonuses, there's ways around the equipment bonuses. ( check slot item ) But I'm not 100% sure how to use this function, let me know where it's wrong.
PHP: 
function onCastSpell(cid, var) 
local lvl = getPlayerLevel(cid) 
local dmgMax = ((lvl * 5))
local dmgMin = ((dmgMax*0.90))
ret = doAreaCombatHealth(cid, COMBAT_PHYSICALDAMAGE, getCreaturePosition(cid), AREA_SMALLSHIELD, -dmgMin, -dmgMax, CONST_ME_GROUNDSHAKER)
return ret
end

The spell doesn't work. I'm trying to achieve a working area spell. I have changed it up to this now:
PHP: 
function onCastSpell(cid, var) 
local lvl = getPlayerLevel(cid) 
local dmgMax = ((lvl * 5))
local dmgMin = ((dmgMax*0.90))
local areaa = createCombatArea{
	{1, 1, 1},
	{1, 3, 1}
}
ret = doAreaCombatHealth(cid, COMBAT_PHYSICALDAMAGE, pos, areaa, -dmgMin, -dmgMax, CONST_ME_GROUNDSHAKER)
return ret
end

Edit; I get no errors on startup.
Here is the function itself that I don't understand parts of: doAreaCombatHealth(cid, type, pos, area, min, max, effect)
I don't understand how to use the pos and area.
Here is the error I get upon using the spell:
Code: 
[20/07/2012 09:31:43] Lua Script Error: [Spell Interface] 
[20/07/2012 09:31:43] data/spells/scripts/attack/enchanted riot shield.lua:onCastSpell

[20/07/2012 09:31:43] luaCreateCombatArea(). This function can only be used while loading the script.

Here is an example of a working spell with this type of format, but it is not an area spell which is where I go wrong.
PHP: 
function onCastSpell(cid, var) 
local target = variantToNumber(var)  
local lvl = getPlayerLevel(cid) 
local dmgMax = ((lvl * 1))
local dmgMin = ((dmgMax*0.50))
local playerTarget = getCreatureTarget(cid)
if(target ~= 0) then 
ret = doTargetCombatHealth(cid, playerTarget, COMBAT_PHYSICALDAMAGE, -dmgMin, -dmgMax, 0)
end 
return ret 
end
Any further questions, please ask.

Well I somewhat got it working, it works for like an area spell which is a decent achievement, but it does not work with wave spells. I had it all set up in spells.xml, I know it wasn't wrong there. But any direction you turn, it casts in the same place. I'm thinking it has something to do with setCombatArea, but I don't know what to connect it to in place of the combat, I tried ret but idk. Here is what I came up with.
LUA: 
local area = createCombatArea(AREA_SQUARE1X1)
function onCastSpell(cid, var) 
local lvl = getPlayerLevel(cid) 
local dmgMax = ((lvl * 3))
local dmgMin = ((dmgMax*0.90))
ret = doAreaCombatHealth(cid, COMBAT_PHYSICALDAMAGE, getCreaturePosition(cid), area, -dmgMin, -dmgMax, CONST_ME_GROUNDSHAKER)
return ret
end

Did you try direction ="1" in spells.xml? also why are you using return ret? just do this
LUA: 
local area = createCombatArea(AREA_SQUARE1X1)

function onCastSpell(cid, var) 
	local lvl = getPlayerLevel(cid) 
	local dmgMax = ((lvl * 3))
	local dmgMin = ((dmgMax*0.90))
	return doAreaCombatHealth(cid, COMBAT_PHYSICALDAMAGE, getCreaturePosition(cid), area, -dmgMin, -dmgMax, CONST_ME_GROUNDSHAKER)
end

yes, i did try direction="1", wouldn't work. and it's because my first spell i made like that had like 4 functions in the ret, and it looked better, then i just started copying and pasting that spell haha, hopefully you can help, thanks in advance.

I don't think it will because I think directions are hardcoded? I could be wrong, but I'm not sure how else you'd do it unless you make the script check the player look direction

I was thinking about that too, but I also strongly believe that it's just a simple line like this: setCombatArea(combat, area). But I'm not sure how to use it without combat, I tried putting ret for combat in the (), but that's a no go, but then again the setCombatArea was set before the ret, but I can't make it local ret =, I'm stumped.

Code: 
function onCastSpell(cid, var) 
local lvl = getPlayerLevel(cid) 
local dmgMax = ((lvl * 5))
local dmgMin = ((dmgMax*0.90))
local areaa = createCombatArea{
    {1, 1, 1},
    {1, 3, 1}
}
ret = doAreaCombatHealth(cid, COMBAT_PHYSICALDAMAGE, pos, areaa, -dmgMin, -dmgMax, CONST_ME_GROUNDSHAKER)
return ret
end

The reason you get an error is because you have local areaa inside your function. Move it outside and try that again.

so..

local area = createCombatArea{}

function onCastSpell()
{
}

I wish that were true. It's not that it's giving me an error anymore, it doesn't work in wave format. I look south, it casts south. I look north, it casts south. i have direction="1" in spells.xml
