isWalkable(cid, pos) error while no tile

[WarOfTheTitans]

My script is checking a position on the map if it is walkable. Sometimes it I remove the tile (there is no tile, a entire black tile) and then I get this error when the script checks the position again:

[26/05/2012 22:40:16] [Error - TalkAction Interface] 
[26/05/2012 22:40:16] data/talkactions/scripts/Dada.lua:onSay
[26/05/2012 22:40:16] Description: 
[26/05/2012 22:40:16] (luaDoTileQueryAdd) Tile not found

Here is the function (from scarlet(omnislash))

function isWalkable(cid,pos)
    local aux = pos
    aux.stackpos = 253
    if doTileQueryAdd(cid, pos) == 1 and getTilePzInfo(pos) == FALSE and getTileHouseInfo(pos) == FALSE and isCreature(getThingFromPos(aux).uid) == FALSE then
        return TRUE
    end
    return FALSE
end

Try this one:

function isWalkable(pos, creature, proj, pz)-- by Nord
        if getTileThingByPos({x = pos.x, y = pos.y, z = pos.z, stackpos = 0}).itemid == 0 then return false end
        if getTopCreature(pos).uid > 0 and creature then return false end
        if getTileInfo(pos).protection and pz then return false, true end
        local n = not proj and 3 or 2
        for i = 0, 255 do
                pos.stackpos = i
                local tile = getTileThingByPos(pos)
                if tile.itemid ~= 0 and not isCreature(tile.uid) then
                        if hasProperty(tile.uid, n) or hasProperty(tile.uid, 7) then
                                return false
                        end
                end
        end
        return true
end

Now it does'nt work anymore:

Post the script maybe?

 

[WarOfTheTitans]

There is nothing wrong in the script. I've seen this error on other scripts like "Bomberman" because they have chosen a wrong directory to the bomberman arena and I get this error because there is nothing on the tile. It's totally black.

[Cykotitan]

function isWalkable(cid, pos)
	pos.stackpos = 0
	if getTileThingByPos(pos).uid ~= 0 then
		local n = getTileInfo(pos)
		if n.protection == false and n.house == false and getTopCreature(pos).uid == 0 and doTileQueryAdd(cid, pos) == RETURNVALUE_NOERROR then
			return true
		end
	end
end
