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.

Implementing security

We already know a lot about the client and the server. We know both their purposes and how to communicate between them. Unfortunately, there are always people trying to ruin the fun by trying to take over your game or exploit it. We already learned how FilteringEnabled prevents a lot of these exploits. However, it cannot stop everything.

So, what can exploiters still do? They are still in control of everything that happens to their own character. Fortunately, this is only the case with their character; they cannot change anything for the characters of other players. The reason for this is because of the network ownership that was explained in the Replication exceptions to FilteringEnabled section.

Besides manipulating their own character, exploiters can do anything that we can do with our LocalScripts. Exploiters basically “inject” a malicious piece of code into the game. Because this is done on their own computer, this is a client-side script...
