Getting started with Roblox scripting: Luau basics for beginners
Posted: Wed Jul 15, 2026 4:55 pm
Getting started with Roblox scripting means learning Luau, the language that powers every game on the platform. The short version: open Roblox Studio, drop a Script into ServerScriptService, learn variables and events, and build tiny things until the pieces click. In this post I will walk through each step the way I wish someone had walked me through it.
[b]What Luau actually is[/b]
Luau is Roblox's own scripting language. The official description on the [url=https://create.roblox.com/docs/luau]Creator Hub Luau page[/url] calls it "a fast, small, safe, gradually typed embeddable scripting language derived from Lua 5.1". Two things there matter for beginners: it is derived from Lua, so most Lua tutorials still apply, and it is gradually typed, meaning you can skip type annotations entirely and add them later. You do not need to think about types on day one.
The Script Editor built into Studio gives you autocompletion, syntax highlighting, and script analysis out of the box, so you do not need to install anything else to start.
[b]Your first script[/b]
Roblox's own [url=https://create.roblox.com/docs/tutorials/fundamentals/coding-1/create-a-script]first script tutorial[/url] takes about two minutes:
[list]
[*]Open Roblox Studio and create a new Baseplate experience.
[*]In the Explorer panel, hover over ServerScriptService, click the + button, and choose Script.
[*]The new script already contains print("Hello world!").
[*]Open the Output window from the Window menu, hit Play, and watch your text appear.
[/list]
That print function will be your best friend for a long time. Whenever your code does something confusing, print the values you are working with and read the Output window. Half of debugging as a beginner is just printing things.
[b]Variables in Luau[/b]
A variable is a named container for a value. In Luau you declare them with the local keyword:
local playerScore = 0
local playerName = "builder123"
local isReady = true
Always use local. It keeps the variable scoped to where you actually need it and avoids polluting the global environment. The common naming convention in Roblox code is camelCase: start lowercase, capitalize each following word, like playerScore or timeRemaining.
Luau has a small set of core data types listed in the official docs: nil (nothing), booleans (true or false), numbers (64-bit floating point), strings (text in quotes), tables (which act as both arrays and dictionaries), and enums (fixed lists used by the Roblox engine). Tables are the one you will lean on constantly later, because almost every collection of data in a Roblox game ends up in one.
One string trick worth knowing early: .. joins strings together, so print("Score: " .. playerScore) prints both in one line.
[b]Events: how Roblox games actually work[/b]
This is the mental shift that separates people who get stuck from people who progress. Roblox is event-driven. You do not write one long program that runs top to bottom; you write small functions and connect them to signals that the engine fires when things happen. A player joins: Players.PlayerAdded fires. A part gets touched: that part's Touched event fires. A character dies: Humanoid.Died fires.
The pattern is always the same shape:
local part = workspace.KillBrick
part.Touched:Connect(function(otherPart)
print(otherPart.Name .. " touched the brick")
end)
Read it as: when this part gets touched, run this function. Once you recognize that Connect pattern, an enormous amount of Roblox code suddenly becomes readable, because everything from touch pads to chat commands to shop purchases uses it.
One modern detail: Roblox recommends the Deferred signal behavior for events, and the [url=https://create.roblox.com/docs/scripting/events/deferred]deferred events documentation[/url] suggests Once() instead of manual disconnection when a handler should run a single time. You mostly will not notice this as a beginner, but it explains why checking a value right after firing an event sometimes behaves oddly.
[b]Common beginner mistakes[/b]
I have watched a lot of new scripters hit the same walls:
[list]
[*][b]Not reading the Output window.[/b] The error messages tell you the exact line number and usually the exact problem. Read them before asking for help.
[*][b]Touched events firing dozens of times.[/b] A part's Touched event fires repeatedly while something moves across it. If your damage brick kills players instantly or your coin gives 40 coins, you need a debounce: a simple boolean variable that blocks the function from re-running until a cooldown passes.
[*][b]Forgetting the difference between Script and LocalScript.[/b] Regular Scripts run on the server, LocalScripts run on each player's device. Code in the wrong one silently does nothing, which is deeply confusing when you do not know why.
[*][b]Copying big free model scripts before understanding small ones.[/b] You learn nothing from pasting a 400-line gun system. Build a door that opens first.
[*][b]Ignoring capitalization.[/b] Luau is case sensitive. workspace and Workspace resolve, but playerscore and playerScore are two different variables and the typo one is just nil.
[/list]
[b]A learning path that actually works[/b]
The order I recommend, based on what has stuck for people I have helped:
[list]
[*]Do the official [url=https://create.roblox.com/docs/tutorials/fundamentals/coding-1/create-a-script]coding fundamentals tutorials[/url] on the Creator Hub. They are short, current, and made for the actual Studio you are using.
[*]Keep the [url=https://create.roblox.com/docs/luau]Luau documentation[/url] open as a reference while you build. When you meet a table or a for loop, read that one page.
[*]Build tiny standalone things: a part that changes color when touched, a door that opens, a kill brick with a debounce, a leaderboard stat. Each one teaches a concept in isolation.
[*]Only then start a "real" game. Your first project ideas will outsize your skills, and small wins keep you going where a giant abandoned project kills motivation.
[*]When you are comfortable, look at [url=https://luau.org/getting-started/]luau.org[/url] for the deeper language side, including the optional type system.
[/list]
Give it a few weeks of building small things regularly and the Connect pattern, variables, and the Output loop will feel natural. Everything else in Roblox development is built on that foundation.
[b]Frequently asked questions[/b]
[b]Do I need to learn Lua before Luau?[/b]
No. Luau is derived from Lua 5.1, so learning Luau directly inside Studio teaches you the Lua fundamentals anyway. Lua tutorials can supplement, but start in Studio where you can see results immediately.
[b]Where should I put my first script?[/b]
ServerScriptService. It is the standard container for server-side game logic, and it is where the official first script tutorial has you create one. Later you will learn about LocalScripts for client-side code like UI and camera work.
[b]Do I need to use Luau's type annotations as a beginner?[/b]
No. Luau is dynamically typed by default, so plain untyped code is completely valid. The optional type system is worth picking up later because it catches mistakes before you hit Play, but it is not a day-one requirement.
[b]How long until I can make an actual game?[/b]
You can build a simple obby with scripted kill bricks and checkpoints within your first couple of weeks. A polished game with shops, saving, and combat is a months-long project. Scale your ambitions to your skills and grow both together.
If you are just starting out, reply below with what you are trying to build, and if you are further along, share the beginner mistake that cost you the most hours. I read every reply in these threads and I am happy to point people at the right next step.
