We need to return the new structure from the meta table

Hi all.
I created a class. It has a class structure. For example inventory, weapons, car, whatever. I need to return the structure from the class.
The autocomplete should work.
No matter what I do, I get the same array back. I need different ones.

Class

local Class = {}
 

local Struct = {
	name = "Def name",
	descr = "Text",			
	max = 110,
	def = 1,
	val= 0,
};
 

function TCopy(t)
	local r = {}
	for k, v in pairs(t) do
		r[k] = v
	end
	return r
end


function Class.new() 
	local ReturnStruct =  Struct;

     --If you copy the original table, everything works correctly. But it's not a pretty solution.
	--Struct=TCopy(Struct);  

	return ReturnStruct;
end

function Class.GetState() 
	
	return 1;
end


return Class;

Include

local  CLASS_Test = require(script.Parent.CLASS_Test);


local Obj1 = CLASS_Test.new();

 

local Obj2 = CLASS_Test:new();
Obj2.name ="BB2";


print(Obj1.name, Obj2.name)


if(Obj1.name ~= Obj2.name)then
	warn("This work");
else
	warn("It is the same object.");
end

Autocomlete. That’s what I mean.

Tables are passed by reference, so no two tables are the same. Try ={ } ~= { } in the console and see the output, you should see false since it’s 2 constructed tables. You’ll have to go with copying the table sadly.

Isn’t there any other way? There are many frameworks, do they copy tables too?

Yes, they also copy tables. It’s really not that big of a deal to copy a table, or I don’t know why you don’t want to do it.

Struct = TCopy(Struct)
I don’t like it because of the extra function you have to keep inside. And in itself looks like a crutch.
I found a built-in (low level) function. It looks more correct.

Struct = {table.unpack(Struct)}
