Questions tagged [roblox]

Roblox is an online development platform, created in 2006, and targeted at children and youth. Roblox uses a modified version of Lua, known as Luau, to support Roblox games.

Roblox is a free user-generated gaming site that makes players the architects of their own 3D worlds. Parts of the platform are a variety of objects, a scripting language and a website to host games. With a free account, one gets a character and a place, that can be customized. [ Source: developer.roblox.com ]

Roblox uses Lua, a lightweight programming language embedded into each game. It is easy to use and allows users to manipulate their games in any way possible. Roblox uses their own version of Lua 5.1, edited to work with the games, called Luau, which features type checking and various optimizations. Luau allows users to do things such as creating their own GUIs, making structures such as sliding doors, adding animation to bricks, teleporting and killing players, etc.

Before posting a question, users should ensure they've used the available debugging tools to collect information about the problem they're encountering.
