Coding is the process of creating instructions for computers to follow. Just like people use different languages such as English and Spanish, so do programs. Roblox uses the coding language Lua.

This article will cover how to start coding in Roblox, introducing common concepts like scripts and variables. By the end, you’ll be able to type out code that displays messages in Roblox Studio

Coding with Scripts

In Roblox Studio , lines of Lua code are held in scripts. These scripts give the game sets of instructions on how to give players health points, create a rain of fireballs, or anything else imaginable.

Creating a Script

Scripts are commonly created in ServerScriptService, a special folder for holding and running scripts.

  1. In the Explorer, hover over ServerScriptService to see the + button.

  2. Click the + button and select Script. This opens the script editor.

  3. Right-click on the Script and select Rename. Type in PracticeScript. Naming scripts is an important way of remember what each one does.

Using the Script Editor

Whenever you create new scripts, the script editor will automatically open up. This is where you will type your code in.

To find the script next time you open up Roblox Studio, click on the name of the script above the game editor, or double-click the script’s name in the Explorer.

Whenever you create a new script, at the top of the script editor, is the print function. Print functions display text to the screen. It’s one of the first functions many people learn since it’s a simple way of giving the script a command.

Below is an example of the print function typed out and it’s output, what you’ll see once the script runs.

1

print

(

"Hello world!"

)

2

Expected Output

1

Hello world!

String Variables

Remember back when you created a script. At the top of it was a message saying “Hello World”. That message in quotations is an example of a string variable type. Variables are containers for information the program can use and change, like player names or points.

Lua variables can hold a variety of data types. Each data type holds a different kind of information, like a number, letter, or even a color. String variables, like the “Hello World”, are a common data type that hold a mix of letters and numbers. String type variables always sit inside of quotation marks, “like this”.

Examples of Strings

Some examples of string variables are below. Notice how they hold a mix of letters and numbers.

  • “You just joined the game!”

  • “There are 50 players left”

  • “10”

To practice using string variables, you’ll code a message in a script.

Typing a Variable

In Lua, while there are different types of variables, you’ll start with local variables, which are found in most scripts. To type variables, start with typing local, followed by a name that describes what that variable should contain.

For example: local myName

In Lua, variables aren’t inherently typed, like other computer languages. While other computer languages, like C#, require you to write the data type in front of a variable, Lua just needs the variable name

Now, try coding it in a script. You’ll write a message to store your favorite animal.

  1. In the Explorer, hover over ServerScriptService. Click the plus sign and select Script. Rename the script to something like VariableTest.

  2. In the script, remove the Hello World message. Start a variable by typing local, then write the variable name, myAnimal.

    1

    local

    myAnimal

    2

    Programmers in Lua use camel case to name their variables. This is a style of writing that uses no spaces, and words are separated with capitalized letters. Such as myVariable or numberStorageArray.

Setting Variables

When a variable is just created, it doesn’t have anything inside. To set it, or put something inside its container, use the = symbol. In this case, you’ll set the variable you created to a string data type.

  1. After the variable name, type =.

    1

    local

    myAnimal =

    2

  2. Still on the same line, type a string variable that describes your favorite animal. Make sure all words and letters are between quotation marks.

    1

    local

    myAnimal =

    "Porcupines are my favorite animal.."

    2

Using Print()

Print functions display text to the screen. It’s one of the first functions many people learn since it’s a simple way of giving the script a command. To see your variable, use the print() function.

  1. On a new line, type print().

    1

    local

    myAnimal =

    "Porcupines are my favorite animal.."

    2

    print

    ()

    3

  2. To print something, it must be inside the parentheses. To print the variable, type it inside, such as (myAnimal).

    1

    local

    myAnimal =

    "Porcupines are my favorite animal.."

    2

    print

    (myAnimal)

    3

Print() can also be used to just print strings, such as print(“My message”). This is useful if you just want to print a quick message.

Testing Output

To test your code, use the Output Window. This window shows print output and errors from scripts.

  1. Select the View menu tab.

  2. Click Output. The window will appear at the bottom of Roblox Studio.

  3. To test the script, press Play. Your new string will show up in the Output window.

    If you see a red error in the output editor, it’s like there’s an error in the code. Each error has a unique way of describing itself. Try and use the information from the error to fix your code.

  4. Since you’ve tested the script, Stop the play- test. You can now return to the Script tab to make any more changes or test out other strings.

Troubleshooting Tips

If the message didn’t appear, try the following tips.

  • Make sure print is lowercase.

  • The string is surrounded by quotation marks:

    “like this”

    .

  • The variable is inside the parentheses like

    (myVariable)

    .

Even though this question is asked 3-4 times a week, the answer remains the same. It changes for everyone person…

Some people will understand better by reading stuff, such as Lua documentation, or the wiki.

Some people will understand better by watching stuff, such as Youtube or the wiki tutorials. This is the way that I learned. I suggest people like Cytheur(Beginner tutorials) or even @SteadyOn tutorials. Even as an experienced scripter, his tutorials are very useful because he is straight to the point and covers a tool not a product, opposed to people like AlvinBlox who does 1 project at a time.

When people refer to “scripts,” they typically mean one of two slightly different concepts. The first, and usually more innocuous, meaning of scripting is using coding instructions to create a Roblox game. However, the second, typically more popular among the younger userbase, uses scripts to gain an unfair advantage in a game. This usually happens by injecting code that changes your character’s capabilities.

How to Use Scripts in Roblox

In this article, we’ll explain some of the basics of Roblox scripting, whether you want to use them for building or breaking down games. Beware, though, that not all scripts are created equal, and using some scripts is punishable with severe measures.

What Are Roblox Scripts?

Simply put, Roblox scripts are parts of code that tell the game engine what to do with a particular object or piece of information. Roblox uses a modified version of LUA, one of the more popular coding and scripting languages. LUA is somewhat simpler than most coding languages but comes with enough functionalities and capabilities to create complex games, given that the programmer knows the ins and outs of scripting.

LUA scripts also benefit from being compatible with various programs and other programming languages, giving them an edge when injecting a piece of code into existing software.

Based on how you want to use scripts, the two script types can differ greatly.

“Hacking” or “cheating” scripts most commonly revolve around changing the data on the client’s side. It gives the user performing these scripts different options, information, and states compared to other players.

This type of Roblox script is typically found in online repositories, and users can download them, usually by paying the contributor, to their device. Hacking scripts need a script injector to work. These programs allow the cheat to run in the client, performing its function while inside the game.

On the other hand, if you’re building a game, you’ll mostly use server-wide or modular scripts to give every player the same gameplay experience and allow them to communicate and encounter each other in the game. The Roblox studio allows for relatively straightforward script management, storage, and editing.

How to Use Roblox Scripts

If you want to use a hacking script, you’ll need to understand that scripts are generally not entirely safe to use. All downloaded foreign scripts will trigger your antivirus warnings since they read as harmful objects.

Additionally, script injectors (the programs that run the scripts) also count as virus software. If you want to use a specific script injector you’ve found alone, research it diligently to ensure it’s safe to use on your PC. Some programs represent themselves as safe script injectors for Roblox but actually pull your user data and other information from your device to outside locations.

Now that you’ve been properly warned about the potential dangers of Roblox scripts, there’s one more thing to cover.

Scripting is considered a bannable offense in most, if not all, games, and Roblox is no different. You can easily lose your account if you want to get even a slightly unfair advantage that negatively impacts other Roblox members and players.

Some people use alternate accounts to test scripts, but even that can be risky with the IP-wide or MAC bans that the Roblox administration sometimes hands out. For more innocuous scripts used in PvE situations, the risks are somewhat mitigated but still exist.

Some of the most reliable and simplest script injectors we’ve found are Synapse X and JJSploit (you can search these up online). They also come with a few general-use scripts to test their capabilities out. Here’s what you need to do to cheat with scripts in Roblox:

  1. Disable your antivirus software. This is a necessary step since script injectors and scripts will be detected as viruses or harmful items. Most antivirus programs won’t let you download them.
  2. Download and install the script injector of your choice. Follow the instructions provided in the installation process.
  3. If you want more than the basic cheats some of these injectors have in their library, you’ll need to find them online. There are several solid options to choose from, with sites like tsunamicheats.com, freerobloxscripts.com, or rscripts.net being generally popular and safe.
  4. Not all scripts work in all Roblox games. If you want to find a specific script to use, you’ll need to crosscheck which Roblox game works for it and which script injector can run it.
  5. Download the script and start the script injector.
  6. Use the tutorial in the script injector to load up the script while running the appropriate Roblox game.
  7. Don’t forget to turn your antivirus protection back on when you’re done.

Can Scripts Be Used in Roblox Mobile?

Unfortunately, the mobile version of Roblox comes with many limitations put in place to allow games to run properly on devices without much processing power. Additionally, scripts usually require the user to root their phone.

Rooting is the process of enabling developer functions on the phone, allowing the user far more control over the system and apps than average. However, if you make a mistake in the rooting process or change something essential for the system to run, you can irreparably break the device.

Additionally, rooting and scripts are most commonly only reserved for the Android system since iOS has more restrictions and safeguards in place.

One of the more popular scripting tools for mobile games that works on Roblox is Game Guardian. It behaves much like a PC script injector, but you need to download every script you want to use on the phone since it doesn’t have a preset library.

Game Guardian is not available through the Google Play Store, so you’ll need to download its APK and run it through the Downloads folder as an executable (much like you download and install programs on the PC). Game Guardian needs to have root access to work, so you’ll need to follow the instructions on how to root your phone if you want to run scripts for any game through it.

After that, the process is relatively simple, if a bit hampered by the lack of a keyboard and mouse setup, making moving files around and copying text more time-consuming.

How to Use Scripts in Roblox Studio

Roblox Studio can be considered a separate, creative part of Roblox where you create games for other members to enjoy. Running scripts in Roblox Studio is encouraged for better aesthetics and performance with a meaningful progression system and gameplay.

Unfortunately, the full extent of LUA coding and how to create a script from scratch are beyond this tutorial. If you want to learn how to code in LUA and Roblox, there are some great tutorials created and maintained by fans. You can use the Roblox community wiki or watch some video tutorials to get you started.

If you just want to put some scripts into Roblox Studio, there are a few ways to go about it. However, the simplest way is to just copy the script’s contents inside your game:

  1. Open the Roblox Studio app.
  2. Hover over ServerScriptServer to make the + icon appear. Click on the icon.
  3. Select Script.
  4. The Explorer will show a new script entry. Right-click on it, then press Rename to rename it as you choose.
  5. Creating a new script immediately shows its script editor in the Studio. The tab will have the name of your script (updated when you rename it).
  6. Clear its contents and copy over the script you want to use.
  7. Make necessary changes if needed, and follow any instructions the script creator provides to link it to your game.

Reinforce Roblox With Scripts

Scripts are necessary if you want to make any progress as a budding Roblox game designer, but it will take a lot of time and effort to create a truly fantastic game. If you’re using scripts to give yourself an advantage in other people’s games, consider the consequences of your actions carefully before you make a move.
