Lua syntax clarification

I’m trying to follow the Roblox Lua style but I have some questions. Java is my first language and basically everything in that language is camelCase (the methods, variables, etc.) whereas the constructors and class names are CamelCase. I notice that roblox uses methods like GetChildren(), so if I’m designing objects in Lua, should I be using CamelCase? It would look weird if I had for say redCar:moveCar() when Roblox uses uppercase syntax. Just wanting my code to look as professional and organized as possible. Please leave me some tips.

Class names, class members are meant to use PascalCase, variable names/parameter names using camelCase.

So think of it somethng like this.

public class RedCar {
    public void MoveCar(int carSpeed) { // using PascalCase yes
        // code that moves car
    }
}

public class Main {
    public static void main(String[] args) {
        RedCar newCar = new RedCar(); // using camelCase for the variable name
        newCar.MoveCar();
    }
}

Rough equivalent of Luau:

local RedCar = { }
RedCar.__index = RedCar

function RedCar.new()
    return setmetatable({ }, RedCar)
end

function RedCar:MoveCar(carSpeed: number)
    -- code that moves car
end

local newCar = RedCar.new()
newCar:MoveCar(50) -- mph

So no you would do RedCar:MoveCar(carSpeed).

Coming from java myself, when creating objects or anything, I tend to use camel-case especially for functions. I believe it is just out of habit. Variable declaration and object declaration can really be done with camel-case or without. For example:

function GameHandler.new(playing : table, act : table)
	local newgame = {}
	newgame.Playing = playing or {}
	newgame.active = act or {}
	print(type(playing))
	return setmetatable(newgame, GameHandler)
end

function GameHandler:checkPlayers(plrs)
	--function
end

As you see the function I created use camel-case. I’m not as familiar with Lua but I’ve have no issue using camel-case.
