Lua Check if target.x offset == an item

[MrVilhelm]

Hi! Me again !

So Im trying Lua again and Im trying to search for a target.x offset. basically what I want is that when you use an item anywhere the script checks if that position you used the item on - 9 x has an object on it.

I tried this but got an error

elseif (target.x - 9):getId() == 2113 then

//I also tried


    local activeTile = {
        x = toPosition.x,
        y = toPosition.y + 10,
        z = toPosition.z
    }

elseif activeTile:getId() == 2113 then

Sadly I failed in both occasions

Error output for the first one : attempt to perform arithmetic on field 'x' (a nil value)
Error output for the second one : attempt to call method 'getId' (a nil value)

EDIT ( Realised I was searching for a x in the first one instead of the Y, but I was searching for the Y, anywho, same error but just wanted to let you know, YES I saw I wrote it wrong XD )

(Assuming you are using TFS 1.3):

local useItem = Action()

function useItem.onUse(player, item, fromPosition, itemEx, toPosition)
    local destinationTile = Tile(toPosition.x - 9, toPosition.y, toPosition.z)
    if destinationTile then
        local itemAtDestination = destinationTile:getItemById(2113)
        if itemAtDestination then
            -- item found at "target.x - 9"
        end
    end
    return true
end

useItem:id(2159) -- item to use
useItem:register()

local useItem = Action()

function leuseItem.onUse(player, item, fromPosition, itemEx, toPosition)
    local destinationTile = Tile(toPosition.x - 9, toPosition.y, toPosition.z)
    if destinationTile then

        end
    end
    return true
end

useItem:id(2159) -- item to use
useItem:register()

Yes TFS 1.3, sorry for that. Forgot that!

Thanks a lot for the answer!

Output I got while trying this :

attempt to index global 'leuseItem' (a nil value)
3: 'end' expected (to close 'function' at line 1) near '<eof>'

But anyways, I read what you did and I got out a working thing atleast ^^ SO thanks a lot

local activeTile = Tile(toPosition.x, toPosition.y + 10, toPosition.z)

elseif activeTile:getItemById(2113) then

final solution ^^

attempt to index global 'leuseItem' (a nil value)

made a typo on line 3

function leuseItem.onUse(...

should've been

function useItem.onUse(...
