Solved TFS 1.2 itemEx bug on certain items.

[whitevo]

I'm doing house building feature for my game and was just testing if all works fine.
Doing that found a TFS bug instead.
when I try to get itemEx, I get a table with 0 values..

Its not really big thing as I can use toPos to create the userdata with top visible thing, But sill. a bug in my book.
wallID 1025

EDIT: how did I fix it in Lua

if not itemEx or type(itemEx) ~= "userdata" then
        local tile = Tile(topos)
        if not tile then return end
        itemEx = tile:getTopVisibleThing()
        if not itemEx then return end
    end

but if you use the wall
item is the item you're using
itemEx is the item you are targeting with if (aka crosshair)
no?

Yes. "itemEx", now renamed "target" in sources is the target item or creature.

pretty sure you can rename any function arguments and they'll still work, as long as they are in the same order
i tried it earlier how he did it and it printed all args for me, dunno why his itemEx wont work

Sure it does, I just emphasize that itemEx is not just item, but can also be a creature. Seems he solved it by himself.
