Is it even possible to do this thorugh metamethods? or would i have to try something else.

My original response

__index only triggers through metatables:

local t = {}

t.__index = function(self, index) --function that runs when a value is indexed
   print("Table indexed:", index) --prints the name of index
end

local metatable = setmetatable({}, t) --sets the metatable of a blank table
local indexTest = metatable.Index --test index

Re-reading your question, Iā€™m a bit puzzled. Are you asking how to get the script line that triggered the __index metamethod?

Yes that is what i am asking. :shallow_pan_of_food:

I think debug.info is what you are looking for.

This example code prints 9, which is the number of the line t[1] = t[1].

local mt = {}

function mt:__index(k, v)
    print(debug.info(2, "l"))
end

local t = {}
setmetatable(t, mt)
t[1] = t[1]
