Lua Help with Script Please -.-"

[KylerXX]

Im trying to do a script that if you cast, creates on target if lookdir is north then this create an item in north, but doesn't work and I dont know why... here is the code:`

function onCastSpell(cid, var)

local directions = {
[0] = {getCreaturePosition(getCreatureTarget(cid)).y - 1, 1987},
[1] = {getCreaturePosition(getCreatureTarget(cid)).x + 1, 1987},
[2] = {getCreaturePosition(getCreatureTarget(cid)).y + 1, 1987},
[3] = {getCreaturePosition(getCreatureTarget(cid)).x - 1, 1987}
}


local dir = getPlayerLookDir(cid)
if directions[dir] == getPlayerLookDir(cid) then
doCreateItem(directions[dir][2], 1, directions[dir][1])
return true
end



end

Here is the error:

[19/07/2010 21:08:59] Lua Script Error: [Spell Interface]

ftw i posted the solution in the other forum you requested it ;/ and it worked for me

function onCastSpell(cid, var)
    local target = getCreatureTarget(cid)
 
    if not isCreature(target) then
        doPlayerSendDefaultCancel(cid, 46)    
        doSendMagicEffect(getThingPos(cid), CONST_ME_POFF)
        return false
    end
 
    local pos, thing = getPosByDir(getThingPos(target), getCreatureLookDirection(target), 1), 2268
 
    if doTileQueryAdd(target, pos) ~= RETURNVALUE_NOERROR then
        doPlayerSendDefaultCancel(cid, 7)    
        doSendMagicEffect(getThingPos(cid), CONST_ME_POFF)
        return false
    end
 
    doCreateItem(2268, 1, pos)        
    return true
end
