🧠 Luau 101: Getting Started with Roblox Scripting#

Welcome to the first post in our Luau Scripting Series! Whether you’re a beginner or just getting started with Roblox development, this post will help you understand what Luau is, why it matters, and how to write your first script.

💡 What is Luau?#

Luau (pronounced “loo-ow”) is a programming language created by Roblox, based on Lua. It’s used to build all the logic behind Roblox games — from character movement to game rules and interactions.

While it’s similar to Lua, Luau has been extended by Roblox to support:

• Type annotations for better code checking
• Improved performance
• Custom APIs for Roblox games

Think of Luau as Lua’s game-dev-optimized cousin, tailored for Roblox!

🛠️ Setting Up: Roblox Studio#

Before writing code, make sure you have Roblox Studio installed:

1. Go to create.roblox.com
2. Sign in and download Roblox Studio
3. Open a new Baseplate project
4. In the Explorer panel, right-click → Insert Object → Script

This creates a Script inside Workspace.

👋 Your First Luau Script: Hello World#

Inside the Script, paste this:

print("Hello, Roblox world!")

Click the Play button at the top. You’ll see the message appear in the Output panel.

✅ Congrats — you’ve just run your first Luau script!

🧱 How Luau Works in Roblox#

Every object in Roblox (like parts, players, GUIs) can have scripts attached.

There are 3 main types of scripts:

• Script: runs on the server
• LocalScript: runs on the client (like the player’s computer)
• ModuleScript: reusable code you can include in other scripts

For now, we’ll mostly use Script.

📌 Summary#

• Luau is Roblox’s custom language for scripting games.
• You need Roblox Studio to start scripting.
• Your first script can be as simple as printing a message.

🧪 Try It Yourself#

Can you make your script print:

• Your name?
• A second message below it?

print("Hello, I'm Mostafa!")
print("Welcome to my Luau series!")
