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:

• Game Logic: Code is used to define the rules and mechanics of the game. This includes controlling player movement, managing game states (such as starting, pausing, or ending the game), implementing scoring systems, and handling interactions between game objects.
• User Interface: Code is employed to create user interfaces within games, such as menus, buttons, and HUDs (heads-up displays). This allows players to navigate the game, customize settings, and access various features.
• Scripted Events: Code is used to trigger events based on specific conditions or player actions. For example, when a player walks into a certain area, interacts with an object, or performs a particular action, code can be used to execute corresponding events, such as playing a sound, spawning enemies, or activating a scripted sequence.
• Character Behavior: Code is used to control the behavior of characters and NPCs (non-player characters) within the game. This includes defining movement patterns, implementing AI (artificial intelligence) for enemies or allies, and creating realistic interactions between characters and the environment.
• Physics and Animations: Code is used to simulate physics and animate objects within the game world. This allows for realistic movement and interactions, such as simulating gravity, collisions, and object animations.
• Customization and Personalization: Code is used to enable customization and personalization features within games. This includes allowing players to customize their avatars, vehicles, or in-game assets using code-driven systems.
• Multiplayer Networking: Code is used to implement multiplayer networking features, enabling players to interact with each other in real time within the game world. This includes synchronizing game state across multiple clients, managing player connections, and facilitating communication between players.

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

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:

• Engine Development: The core engine that powers Roblox games, including rendering, physics, networking, and audio systems, is written in C++.
• Platform Infrastructure: C++ may be used for developing and optimizing various platform components, such as the Roblox client application, server software, and backend systems.
• Performance Critical Components: C++ is often used for implementing performance-critical components that require low-level optimization, such as graphics rendering, physics simulation, and networking protocols.

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:

• Simplicity: Lua has a clean and simple syntax that makes it easy to learn and use. Its syntax is inspired by other programming languages like C and Pascal.
• Embeddable: Lua is designed to be embedded into other applications as a scripting language. It’s often used as a scripting engine for game engines, applications, and software frameworks.
• Dynamic Typing: Lua is dynamically typed, meaning variables do not have a fixed type and can hold values of any type. This makes Lua flexible and suitable for rapid development.
• Table-based Data Structure: Lua uses tables as its primary data structure, which are associative arrays that can store key-value pairs. Tables are extremely versatile and can be used to represent arrays, dictionaries, objects, and other data structures.
• First-Class Functions: Functions in Lua are first-class citizens, meaning they can be assigned to variables, passed as arguments to other functions, and returned from functions. This makes Lua suitable for functional programming paradigms.
• Coroutine Support: Lua includes built-in support for coroutines, which are lightweight cooperative multitasking units. Coroutines allow developers to write asynchronous and event-driven code in a synchronous style.
• Garbage Collection: Lua features automatic memory management through garbage collection. It automatically deallocates memory when objects are no longer in use, helping developers avoid memory leaks and manual memory management.
• Extensibility: Lua is highly extensible and customizable. It allows developers to define custom data types, operators, and syntax extensions through metaprogramming techniques.
• Portability: Lua is designed to be highly portable and platform-independent. It can be compiled and run on various operating systems and hardware architectures with minimal changes.

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.
