Sling

A modern and reactive backpack UI for Roblox.

About

Sling is a modern and reactive backpack UI designed for Roblox experiences. It replaces the default backpack system, giving you complete freedom to customize the interface however you want, dynamically categorize inventory items, and use or create custom themes.

Features

• Custom Categorization 🎒 - Group your inventory items into tab categories (e.g., Weapons, Potions, Resources) using simple, custom declarative predicate functions.
• Custom Themes 🎨 - Customize theme properties, switch between predefined themes (default and light), or define your own.
• Subscribe to Events 🔔 - Track when the player interacts with their backpack, equips items, or when items are added/removed.
• Manage Hotbar 🔢 - Track when the user rearranges items and programmatically set which items should be placed in the hotbar.

Installation

Github Releases

1. Download the sling.rbxm model file from the Github Releases.
2. Open Roblox Studio and create a new place or open an existing place.
3. In the Explorer window, insert Sling into ReplicatedStorage.
4. Select the Sling model file you downloaded from GitHub.

Sling uses RunContext to run anywhere, so you do not need to move it from Workspace, though it is recommended to parent it to ReplicatedStorage for better practices and organization.
