this function decodes a table and turns it into a part, although it tried to return nil (i added a back, that is the “What?”)

This is what an input table looks like for it:

But it cant recognize the type?

#2

Is the table output screenshot the table you use for PartTable, or something else? If it’s the same, you’re trying to get the length of a dictionary with PartTable[#PartTable] instead of PartTable.Type.

#3

im getting the lencgth because type is always the last index, and that table output is the one going into the func

#4

This is not how dictionary keys work in Luau. Getting the length of a dictionary via the # is not possible, only via proper arrays.

#5

Why not just pass the type to the function along with the table?

#6

because i have to have all the data to recreate the part

#7

oh wait nvm i see what ur saying lemme try that

#8

just tried it, its still not working

#9

You’re hardcoding this a LOT. Honestly, I recommend rewriting it entirely more optimized and cleaned up. But the main issue is you’re using #'s for tables and you can’t.

#10

And all of that information would still exist within the function, all you need do is pass the type as a second input to the function:

local function DecodePart(PartTable,PartType)

	if PartType == "BasePart" then
	...
end
#11

yeah i just did that, its printing out as nil?

#12

oh my god i was passing the wrong table…
i was printing the right table but sending the wrong one, ill respond it it works now

#13

yes but im having issues with meshes, mesh id and the double sided property:

(Not material thats fine)
it says i need a plugin to do it?

#14

Not sure, are you sure that DoubleSided and MeshId are being assigned from a correct storage container?

#15

MeshIds and not directly changeable. You’ll have to insert a copy of the mesh via InsertService:CreateMeshPartAsync() instead. The property DoubleSided is still unchangeable with this, however.
