OOP Formatting Help

Help and Feedback Code Review
#1

I recently started to learn OOP from this tutorial All about Object Oriented Programming. But, I saw that their is a lot of different ways to format your code. The way I’m currently formatting everything looks like this.

local Test = {}

Test.__index = Test

function Test.new()
	local newtest = {}
	setmetatable(newtest, Test)

	newtest.number = 5
	newtest.text = "Test"
	
	return newtest
end

function Test:DoSomething()
	print("Test")
end

return Test

I was wondering if their is a better/cleaner way to implement this.

It looks good to me. The only thing that you might change is the code style. There is an article about it for Lua/Luau in Roblox (from roblox.github.io): ‘Roblox Lua Style guide’.

Because Lua doesn’t have true OOP support there are different methods of doing it but this one works fine as is the most common method people use.

I would recommend when creating new Test objects, set the __index of that object to itself in case you were to add objects within objects.

I personally prefer doing it this way:

function Test.new()
        return setmetatable({
                  number = 5,
                  text = "Test"
         }, Test);
end
