Universal Inventory Toolkit

A complete, modular, and plug-and-play inventory solution for Unity.

Pick up items, store them in chests, equip them instantly - and see them appear right in your hands, without writing a single line of code.

Universal Inventory Toolkit combines everything you need to build a professional-grade inventory system: drag-and-drop between windows, auto-saving chests, filtered slots for crafting and equipment, and realistic in-hand item visualization.

Lightweight, flexible, and production-ready - works instantly in URP, HDRP, and Built-in.

Key Features

Fully functional out of the box - just import, drop prefabs into your scene, and everything works instantly.

Modular architecture - use only the systems you need: quick slots, chests, filtered slots, or item visualization.

Seamless item pickup straight from the world - no extra setup or coding.

Quick slots with intuitive control (1–0 keys or mouse scroll) - just like in the best survival games.

Advanced Drag & Drop system - move items between windows, chests, and filtered slots as naturally as in AAA titles.

Smart stack handling - supports stackable and unique items with custom limits, like Minecraft or Rust.

Auto-saving chests - all stored items persist even after restarting the game.

Filtered slots - ideal for crafting, equipment, or quest logic (e.g., “key-door” mechanics).

In-hand item visualization - adjust position, rotation, and scale for any camera or player setup.

Dynamic audio system - customize pickup, drop, and impact sounds for every item.

Full C# source code - clean, extensible, and ready for any customization.

True Plug & Play - no dependencies, third-party libraries, or complex setup. Works in URP, HDRP, and Built-in.

Universal Inventory Toolkit isn’t just an inventory - it’s the foundation for your next game.

Build projects in the style of Rust, The Forest, DayZ, or Minecraft - without writing a single extra line of code.

Perfect for FPS, survival, crafting, RPG, and sandbox projects
