How to open the Lua script editor in Roblox Studio
To open a Lua script in Roblox Studio, you need to create a new script object inside your game workspace, then double-click it to open the editor window. The script editor is built directly into Studio — there is no separate program to download or install. Once you double-click a script, a text window appears where you can write and edit Lua code.
The most common way to create your first script is to right-click on a part in your workspace, select Insert Object, then choose LocalScript or Script depending on what you need. After you create it, the script appears in the Explorer panel on the left side of Studio. Double-clicking the script name opens the editor.
Key Takeaways
- Right-click any part in your workspace and select Insert Object, then Script or LocalScript to create a new script file.
- Double-click the script name in the Explorer panel to open the Lua editor window where you write code.
- LocalScripts run on the client side (the player's computer) while regular Scripts run on the server, which affects what code you can write.
- The editor includes basic syntax highlighting and error messages at the bottom of the window to help you find mistakes.
- You can also create scripts by dragging them from the Toolbox into your workspace if you want to start with a template.
Creating a script from the workspace
The fastest way to open a Lua editor is to create a script directly in your game world. Click on any part in your 3D workspace to select it, then right-click and look for the option that says Insert Object. A menu appears with different object types you can add.
From that menu, select either Script or LocalScript. A Script runs on Roblox's servers and controls game logic that affects all players. A LocalScript runs only on one player's computer and is often used for things like camera controls or user interface responses. For your first script, either one will open the editor the same way.
Once you create the script, it appears in the Explorer panel on the left side of Studio. You will see it listed under the part you right-clicked on. The script name usually starts with "Script" or "LocalScript" followed by a number. Double-click that name to open the editor window.
Opening the editor window
Double-clicking a script in the Explorer panel opens a new window with the Lua code editor. This window floats on top of Studio and shows line numbers on the left side. The editor comes with some default code already written — you can delete this and start fresh, or modify it for your needs.
If you accidentally close the editor window, you can reopen it by double-clicking the script name again in the Explorer. The script itself is not deleted when you close the window — closing the window just hides the editor. Your code stays saved in the script object.
The editor window has a dark background by default, with colored text for different parts of the code. At the bottom of the window, you will see an Output section that shows error messages when your code does not work. These messages tell you which line has the problem and what went wrong.
Understanding Script vs. LocalScript
Roblox Studio offers two main script types, and which one you use changes what your code can do. A Script runs on Roblox's servers and can change things that all players see — like moving a platform or awarding points. A LocalScript runs only on one player's computer and can only change things that player sees — like their camera angle or their own screen display.
If you want to write code that affects the whole game world, use a regular Script. If you want to write code that responds to one player's actions, use a LocalScript. You can have both types in the same game, and they work together — the Script handles shared game logic while LocalScripts handle individual player input.
When you are learning, start with a Script in the workspace. It is easier to see what your code does when it affects something visible to everyone. Once you understand the basics, you can experiment with LocalScripts to learn how player input works.
Using the Toolbox to find script templates
Roblox Studio includes a Toolbox panel that holds pre-made scripts and objects you can drag into your game. To open the Toolbox, click the View menu at the top of Studio and select Toolbox, or press Ctrl+Shift+T on Windows or Cmd+Shift+T on Mac. A panel appears on the right side of the screen.
In the Toolbox, you can search for script templates by typing keywords like "spawn" or "damage". When you find a script you want, drag it into your workspace. The script opens in the editor automatically, and you can see how it works and modify it for your game. This is a good way to learn how other people write Lua code for Roblox.
Templates are not required to open the editor — you can always create a blank script and write from scratch. But templates show you working examples of common tasks, which helps you understand the patterns Roblox scripts follow.
Fixing common mistakes when opening scripts
If you create a script but do not see it in the Explorer panel, check that you right-clicked on an actual part in the workspace. You cannot insert a script into empty space — it has to be inside or attached to a game object. If you right-clicked on nothing, the Insert Object menu will not appear.
If you double-click a script and nothing happens, the editor window may have opened behind the main Studio window. Look at your taskbar or try clicking on the Studio window and then double-clicking the script again. Sometimes the editor window opens but is hidden behind other windows.
If the editor window opens but shows an error message immediately, that usually means the default code in the script has a problem. This is normal — you can delete the default code and write your own. The error does not mean the editor is broken; it just means the template code needs to be fixed or replaced.
Frequently Asked Questions
Can I open Lua scripts in a different text editor like Notepad?
Roblox Studio's built-in editor is the standard way to write scripts, and it is designed to work with Studio's testing tools. You can use external editors to write Lua code, but you would have to copy and paste it into Studio manually. Most people use the built-in editor because it shows errors as you type and connects directly to your game.
What is the difference between the Output window and the editor window?
The editor window is where you write your code. The Output window at the bottom shows messages from your code when it runs — things like errors, warnings, or text you told the script to print. You write in the editor, then run the game to see the results in the Output window.
Do I need to save my script after I write code?
No. Roblox Studio saves your scripts automatically as you type. You do not need to press Ctrl+S or use a File menu. When you close the editor window, your code is already saved in the script object.
Can I have multiple scripts open at the same time?
Yes. You can double-click different scripts to open multiple editor windows. Each script opens in its own window, and you can switch between them. This is useful when you need to look at how two scripts interact with each other.
What happens if I delete a script by accident?
If you right-click a script in the Explorer and select Delete, the script is removed from your game. You can undo this by pressing Ctrl+Z immediately. If you close Studio without saving, the deletion is permanent, so be careful when deleting scripts you might need later.
