GetPlacedFurnitureChildren return type

Hi and sorry to bother you guys, but [and please tell me if I am crazy] the return type for the function...

GetPlacedFurnitureChildren( id )

...may be a data type that isn't native to LUA (perhaps a C array that isn't cast for LUA? I am not sure how the game's host C++ executable passes data to/from the LUA interpreter)

The steps to reproduce this issue are:

1. Link multiple children to a parent item.
2. Use a statement similar to the following:

/script d( type( GetPlacedFurnitureChildren( parentItemId ) ) )

What I am seeing is "number", even though a statement such as...

/script d( GetPlacedFurnitureChildren( parentItemId ) )

...will output a 'list' of furniture Ids (the children). Interacting with this return value as if it were a table produces the standard "Operator # (or whatever) is not support for # number" error.

The strange part - and the reason why I think the return value may be cast incorrectly for LUA - is that the output is clearly a table, or at least an array-like structure.

The end result though is that I cannot index any id in the list beyond the first one as LUA refuses to allow it to be referenced as a table. I hope this information helps!

Thank you so much!

I just tried it myself and from what I see, the function returns a variable number of id64 values.
The missing entry for ESOUIDocumentation would probably look like this:

* GetPlacedFurnitureChildren(*id64* _furnitureId_)
** _Uses variable returns..._
** _Returns:_ *id64:nilable* _childFurnitureId_

In order to iterate over them you could use one of the following approaches:

Lua Code:

function test(...)
    for i = 1, select("#", ...) do
        local childId = select(i, ...)
        d(Id64ToString(childId))
    end
end
test(GetPlacedFurnitureChildren(HousingEditorGetSelectedFurnitureId()))
 
function test2()
    local childIds = {GetPlacedFurnitureChildren(HousingEditorGetSelectedFurnitureId())}
    for i = 1, #childIds do
        local childId = childIds[i]
        d(Id64ToString(childId))
    end
end
test2()

P.s. Moved the thread since it doesn't belong in the wishlist.
