setmetatable() not working

[overki11]

Hey, I'm at my wits end. setmetatable() is not working and I have no clue why.

I've added two debug messages in the code, and I'll show the output after. Here is a function I made to setmetatable and output a function

function inv:New()
	local r = setmetatable({}, inv)
	print(r.AddSlot)
	print(inv.AddSlot)
end

Output in console when function is called:

nil
function: 0x3bcc2be0

As you can see, for some reason r does not take the function AddSlot when metatable is set. I have done inv.__index = self

I have no clue what is going wrong.

Where have you done inv.__index = self? And what is self?

local inv = {}
inv.__index = inv

function inv:AddSlot() end
function inv:New()
  local r = setmetatable({}, inv)
  print(r.AddSlot)
  print(inv.AddSlot)
end

inv:New()

Prints out the same function twice for me.

That's it. I'm so stupid. I thought for some reason self applied when I assigned __index.
