Lua OOP Design

[perbone]

The idea is to design how OOP will work in Lua and Godot. Classes will be implemented with tables and should be as close as possible to the Godot API used by other languages.

Following below is an excerpt for some of the the designs I have so far.

1. Explicitly imports the class Lua module and the node class to be extended and defines new classes through the class's 'extends' method

Although more verbose it gives a classic oop look and feel

local class = require 'lua.class' -- Import the system class library
local Sprite = require 'godot.Sprite' -- Make sure to import the base class

local Main = class.extends(Sprite) -- Creates the user subclass

function Main:ready()
end

function Main:process(delta)
end

return Main

2. Explicitly imports only the node class to be extended and defines new classes through the implicity available 'extends' method

This is more streamlined and concise and gives a mixed oop look and feel

local Sprite = require 'godot.Sprite' -- Make sure to import the base class

local Main = extends(Sprite) -- Creates the user subclass

function Main:ready()
end

function Main:process(delta)
end

return Main

Please share your thoughts on this two ideas or show us a new idea that you come up about this topic.

local Sprite = require 'godot.sprite'
local Main = Sprite:extend()

function Main:ready()
end

function Main:process()
end

return Main

I think it gets cleaner and more pleasurable.
_ before de method name is a gdscript thing, don't need to bring it to lua.

If anything it should be done similar to the Roblox OOP style
