TFS 1.X+ Problem with getItemById

[Roni123]

Good Morning,

Dears,

I have trouble with getItemById problem, when I use lever on Demon Helmet Quest then i got this message in console:

Lua Script Error: [Action Interface]
data/actions/scripts/demonHelmetQuest/demonHelmetQuestLever.lua:onUse
...tions/scripts/demonHelmetQuest/demonHelmetQuestLever.lua:9: attempt to call method 'getItemById' (a nil value)
stack traceback:
        [C]: in function 'getItemById'
        ...tions/scripts/demonHelmetQuest/demonHelmetQuestLever.lua:9: in function <...tions/scripts/demonHelmetQuest/demonHelmetQuestLever.lua:7>

My DHQ action:

local positions = {
    Position(33314, 31592, 15), -- stone position
    Position(33316, 31591, 15), -- teleport creation position
    Position(33322, 31592, 14) -- where the teleport takes you
}
 
function onUse(player, item, fromPosition, target, toPosition, isHotkey)
    if item.itemid == 1945 then
        local item = positions[1]:getItemById(1355)
        if item then
            item:remove()
        end

        local teleport = Game.createItem(1387, 1, positions[2])
        if teleport then
            teleport:setDestination(t[3])
            positions[2]:sendMagicEffect(CONST_ME_TELEPORT)
        end
    elseif item.itemid == 1946 then
        local item = positions[2]:getItemById(1387)
        if item then
            item:remove()
        end

        positions[2]:sendMagicEffect(CONST_ME_POFF)
        Game.createItem(1355, 1, positions[1])
    end

    item:transform(item.itemid == 1945 and 1946 or 1945)
    return true
end

I have trying to find something on otland but without effect :/

Except:
getItemById
Try:
getUniqueId

 

[Infernum]

no, it's a tile method but you're using it on position
create tile by using Tile(pos)

Problem has been solved by using this script,

local pinkstonepos1 = {x=634, y=664, z=13}        -- Remember to
local TeleportToPos = { x = 645, y = 660, z = 12} -- adjust the
local TeleportInPos = { x = 636, y = 662, z = 13} -- coordinates here
local LeverPos      = { x = 647, y = 663, z = 13} -- to your map :)
local timeToRemove  = 20 -- in seconds

function onUse(cid, item, frompos, item2, topos)

local pinkstone1 = getTileItemById(pinkstonepos1, 1355) -- If you do not want a pink stone, change this itemID to whatever itemID you want to use
local teleport = getTileItemById(TeleportInPos, 1387)

        if item.itemid == 1945 then

            doRemoveItem(pinkstone1.uid, 1)
            doCreateTeleport(1387, TeleportToPos, TeleportInPos)
            doSendMagicEffect(TeleportInPos, CONST_ME_TELEPORT)
            doPlayerSendTextMessage(cid,22,"Click!")
            addEvent(doRemoveTeleport, timeToRemove * 1000)

    else if item.itemid == 1946 then

        doPlayerSendCancel(cid,"Sorry, not possible.")

    return 1

    end
end 

end

function doRemoveTeleport()

local teleport = getTileItemById(TeleportInPos, 1387)
local Lever = getTileItemById(LeverPos, 1946)

    if teleport.uid > 0 then

        doCreateItem(1355, 1, pinkstonepos1)
        doRemoveItem(teleport.uid)
        doSendMagicEffect(TeleportInPos, CONST_ME_POFF)
        doTransformItem(Lever.uid, 1945)

    end

end

What @Infernum says is that you should use the method like this:

local item = Tile(positions[1]):getItemById(1355)
