First Time Using Metatables | Global Use Metatable Module Test

Help and Feedback Code Review
#1

I’ve never used Metatables before, but I believe I should’ve learned them previously so, is what I’m doing here not the worst way you can do it? Is there anything to improve on, as the way I went about this was from methods presented years ago, so I was interested if it was any outdated.

This is a simple Module return, and print values that utilize a Metatable, or something.

RBXL

Metatables.rbxl (53.7 KB)

Scripts inside RBXL
Global_Script 
local Globals = {}

Globals.TestGlobal = {}

return Globals
Test_Module 
local TestModule = {}

function TestModule:PrintSomething()
	print("Something")
end

function TestModule.Init()
	local Metatable = {}
	setmetatable(Metatable, TestModule)

	Metatable.TestValue = "Test_1"
	Metatable.TestValue2 = "Test_2"
	Metatable.ModuleFunctions = TestModule

	return Metatable
end

return TestModule
Startup_Script 
local Globals = require(script.Parent.Globals)
local Test = Globals.TestGlobal

local TestModule = require(script.Parent.TestModule)

-------//

Test["NewThing"] = TestModule.Init()

-------\\ Can Call Across Multiple Scripts

print(Test["NewThing"].TestValue)

Test["NewThing"].ModuleFunctions:PrintSomething()

I’m not sure what you are trying to obtain with this.

It’s a simple test that allows certain data to circulate through scripts using the module, it was question if the method of doing so was not outdated and wouldn’t be un-optimized or a “bad way of doing it”.

#4 
--Test module script 
local TestModule = {}
TestModule.__index = TestModule --When we create a new 'object' we need to say which table it should create.

function TestModule:PrintSomething()
	print("Something")
--you could add this line
        print(self.TestValue)
end

function TestModule.Init()
	local Metatable = {}
	setmetatable(Metatable, TestModule)

	Metatable.TestValue = "Test_1"
	Metatable.TestValue2 = "Test_2"
	Metatable.ModuleFunctions = TestModule --This is not necessary, you can use 'Metatable:Print something()', the methods defined in TestModule are available to the newly created Metatable object.

	return Metatable
end

return TestModule

I use the same method of accessing metatable objects from different scripts, and I can’t think of another way which is simpler!
(Edit : to clarify language)

I forgot index, was meant to be there just thought I was wrong and made a workaround for function calling since I didn’t notice I didn’t add it. Was also looking to advance to self but I didn’t try to do it yet.
