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.

Exercise 5.1 – greeting an NPC

In this exercise, we will make a greeting system compatible with StreamingEnabled. There will be an NPC on the map that constantly plays idle animations. A waving animation will start on the NPC if the player comes near the player. At the same time that the NPC is waving, the player near the NPC should wave, too. The waving animation of the NPC should not replicate in other clients. This means that the NPC is only waving for the player near the NPC, not for other players that see the NPC but are not close to it.

There are multiple ways of implementing this system. There will be steps to make this system next. However, you are not required to follow those steps. If you know a better way or want to experiment yourself, feel free to try it on your own. Just make sure your system meets all the previously mentioned criteria.


We will start by setting up the game from an empty Baseplate template:
