These two terms are often confused. This page explains what Roblox scripts and game mods are, how they work, and what the risks are—using language that is easy for beginners to follow.

What is a Roblox script?

Roblox script is a piece of code that issues commands to objects, players, and systems within a Roblox game.  Everything that moves, reacts, or calculates scores in a Roblox game is driven by scripts. The language used is Luau, a derivative of Lua that has been optimized for speed and supports type checking. 

In Roblox Studio, there are three types of scripts you need to know:

• Script: Runs on the server. Suitable for critical logic such as player data, scores, and purchases.
• LocalScript: Runs on the player's device. Used for the user interface, camera, and input.
• ModuleScript: contains functions that can be reused by other scripts, resulting in cleaner code.

How to start learning to create scripts and mods

If you want to create it yourself, the process differs between Roblox and PC game mods:

Roblox:

1. Install Roblox Studio and create a blank project.

2. Learn the basics of Luau: variables, functions, conditionals, and loops.

3. Follow the official Roblox Creator documentation, then create small mechanics such as doors, a scoring system, or buttons.

Game Error:

1. Choose a single-player game with an active modding community.

2. Find the mod loader used by the game and read its documentation.

3. Start with small changes—such as displaying a message or altering a single value—and build from there.
