Overview of this book

Roblox is a game platform with over 47 million daily active users. Something unique to Roblox is that you’re playing games made by other gamers! This means that you can make your own games, even if you have no experience. In addition, Roblox provides a free engine that allows you to create and publish a simple game in less than five minutes and get paid while at it. Most Roblox games require programming. This book starts with the basics of programming in Roblox Luau. Each chapter builds on the previous one, which eventually results in you mastering programming concepts in Lua. Next, the book teaches you complex technologies that you can implement in your game. Each concept is explained clearly and uses simple examples that show you how the technology is being used. This book contains additional exercises for you to experiment with the concepts you’ve learned. Using best practices, you will understand how to write and build complex systems such as databases, user input controls, and all device user interfaces. In addition, you will learn how to build an entire game from scratch. By the end of this book, you will be able to program complex systems in Roblox from the ground up by learning how to write code using Luau and create optimized code.

Using functions

In this section, we will start using something called functions. Let us start by finding out when to use functions. In Chapter 1, Getting Up to Speed with Roblox and Luau Basics, we saw the following code:

local playerPosition = 1
-- Checking if the player's position is a valid number
if playerPosition >= MINIMUM_PLAYERS and playerPosition <= MAXIMUM_PLAYERS then
    -- Getting correct message based on player›s position
    if playerPosition <= 3 then
        print("Well done! You are in spot " .. playerPosition 
        .. "!")
    elseif playerPosition <= 5 then
        print("You are almost there!")
        print("You are not in the top three yet! Keep going!")
