Lua Find item with action id on map

[andu]

Somewhere, randomly on a map my script spawned an item with random actionid between 1000 and 2000
Do we have in TFS 1.2 function what will let me find that item's coordinates with lua script?

Example, player click on Treasure Map and description appears: "Treasure coordinates are: x, y, z"

example logic:

function onUse...
local item = searchMapForItemWithActionId(1000)
local itemPos = item:getPosition()
...

I don't think so.
You can look full map but it will not be a nice way.
If i have to do something like that, when i spawn the item, i store the item userData in a global table with the Position(x,y,z) as index, then if i need to find the item, just look if the index exist...

function spawnMyItem(item, position)
    Game.createItem(item, 1, position)
    myGlobalTable[position] = {itemData = item, randomVariable = "blablabla"}
end

function findMyItem(position)
    if myGlobalTable[position] then
        return myGlobalTable[position].itemData
    end
end

Something like that... If you move, remove, alter the item, just alter the table too.

controlling the item before creation (until closing server):

if not specialItems then -- prevent wiping after reload
specialItems = {}
end

theItem = game.createItem(id, count, pos)
table.insert(specialItems, theItem:getUniqueId())

function something(searched)
    for i = 1, #specialItems do
       local item = Item(specialItems[i])
        if item then
            if item:getActionId() == searched then
                return item
            end
        end
    end
end

or search database attributes somehow

You could do it with unique ID just by doing
item = Item(2000) if item then pos =item:getPosition() end
