Roblox GUI/UI Systems Reference

1. Overview

Load this reference when working on any UI-related task in Roblox:

• Building menus (main menu, pause menu, settings)
• HUDs (health bars, minimaps, ammo counters, score displays)
• Shops and inventory screens
• Notification and toast systems
• Dialog and popup windows
• Any 2D or 3D-attached interface elements

All GUI code runs on the client (LocalScripts). UI objects live under StarterGui at edit time and are cloned into each player's PlayerGui at runtime.
