Roblox is a family-friendly online gaming platform that has over 40 million different games and 70 million players. 

It’s a favorite among kids and what makes Roblox unique is that it’s a user-created game platform. The games are made by developers and creators and, surprisingly, many of them are kids and teens. 

Anyone can build a game with Roblox’s free development application, Roblox Studio. It is also an excellent resource and tool for kids interested in learning coding and game development. Besides coding fundamentals, building their own game in Roblox encourages your child’s creativity and entrepreneurship.

This article guides you through what you need to know about Roblox coding and how your child can get started.

Kids can also learn how to build their own Roblox game with a live instructor in our 1-week Roblox camps.

Overview of Coding in Roblox

What is Roblox?

Roblox is a gaming platform that hosts millions of immersive experiences created by its community of users. It was created by co-founders David Baszucki and Erik Cassel in 2004 and officially launched on September 1, 2006.

Roblox builds the tools and platform that empower people to create their own experiences. Roblox itself is not a game and the company does not produce games. However, they create the tools and technology for others to do so. 

In Roblox, players can explore immersive experiences from gaming to social hangouts, concerts, sports, fashion shows, education, and entertainment. It also has a virtual economy where players trade, earn, and spend virtual currency and resources.

Roblox is especially popular among kids with over 60% of users being under the age of 16. Kids can play, create, and learn in a safe environment within Roblox. 

How Is Code Used in Roblox? 

Code is used extensively in the Roblox platform to create games and experiences. Developers and creators write code and scripts in Roblox Studio. 

The code is what shapes the gameplay experience in Roblox and allows developers to create immersive and engaging experiences for players to enjoy. 

Whether it’s designing complex game mechanics, creating dynamic environments, or implementing social features, code is the backbone of the Roblox platform and its diverse range of games.

Code affects all aspects of game development including:

Most of the coding done in Roblox happens in Roblox Studio.

What is Roblox studio?

Roblox Studio is the official development tool provided by Roblox Corporation for creating games and experiences within the Roblox platform.  

It provides a user-friendly interface for designing 3D environments, scripting game logic, and publishing your creations to the Roblox platform. It’s so easy that kids can create a simple Roblox obby in just 15 min.

In Roblox Studio users can create:

Key features of Roblox Studio include:

Roblox Studio empowers kids of all skill levels to unleash their creativity and bring their ideas to life in Roblox, whether they’re aspiring game developers, artists, or designers. It serves as the primary platform for users to create and share their own interactive experiences.

To build more advanced games, it will require some level of coding in Roblox Lua. 

What coding language is Roblox written in?

The Roblox platform itself is written in C++ and other languages, but the most important language for anyone interested in Roblox coding is Lua.

Roblox Games Are Written in Lua

The Roblox studio program itself is written in C++ along with other languages. Roblox games and experiences are primarily written in Lua, a lightweight and versatile scripting language. 

Lua is widely used in game development due to its simplicity, flexibility, and ease of integration with various game engines and platforms.

Roblox has adapted the Lua programming language to their platform and games are made with a derivative of the language Lua named Luau. 

The main difference between Lua and Luau is that Luau has optimizations that make it faster and more efficient. This results in better performance for games and other experiences developed on the Roblox platform. Luau also includes some new features and functionality that are not available in regular Lua. If you know how to code in Lua, learning Luau is relatively easy.

In Roblox Studio, Lua is used to script game logic, control gameplay mechanics, and add interactivity to objects and characters within the game world. Developers write Lua scripts to define how game elements behave, respond to player input, and interact with each other.

While Lua is the primary language used for scripting in Roblox, developers may also utilize other programming languages for backend systems, server-side logic, or external integrations. 

However, Lua remains the dominant language for creating and scripting games within the Roblox platform.

Does Roblox use C++?

Roblox primarily uses Lua for scripting within its games and experiences. So, if you want to develop games, learning Lua is the best option.

However, the underlying engine and infrastructure of Roblox, which includes the Roblox client and server software, are built using a combination of programming languages, including C++.

C++ is a widely used programming language in game development due to its performance, flexibility, and low-level capabilities. It is often used to develop game engines, core systems, and performance-critical components.

In the case of Roblox, C++ is likely used for various aspects of the platform, including:

While Lua is the primary language used for scripting gameplay logic within Roblox games, C++ plays a crucial role in powering the underlying technology and infrastructure that supports the Roblox platform as a whole.

Is Roblox coded in Python?

No, Roblox itself is not primarily coded in Python. Roblox games and the Roblox platform itself are primarily built and scripted using Lua and C++.

Python is a popular programming language known for its simplicity and readability. It’s the language kids start with in our middle and high school coding programs because it’s in demand and easy to learn.

While Python is widely used in various fields, including web development, data science, and automation, it is not commonly used for game development within the Roblox ecosystem.

Everything About Programming in Lua

Lua is a lightweight, high-level, and versatile scripting language commonly used in game development, embedded systems, and other applications where simplicity and flexibility are desired. 

A version of Lua, Luau, is the primary scripting language used within the Roblox platform to build games. 

For kids, Lua has a straightforward syntax and minimalistic design that make it easier to grasp fundamental programming concepts without overwhelming complexity.

Learning Lua enables kids to customize and create their own games within Roblox, providing a hands-on and practical application for their programming skills.

Example Script

Can you guess what that script does? It changes the color of a part when a player touches it.

Here are some key features and aspects of Lua programming:

Lua’s versatility and ease of integration make it a popular choice for game development, scripting engines, and various other applications.

Kids should start with an introduction to scripting in Lua if they want to code Roblox games.

Introduction to Scripting

Lua scripting in Roblox is the process of writing code in the Lua programming language to create interactive experiences, gameplay mechanics, and dynamic content within Roblox games. 

Whether you’re a kid or a beginner, Lua scripting in Roblox offers a fun and rewarding way to bring your ideas to life and create your own games.
