Quick Inventory Pro - Inventory System

Quick Inventory Pro is a complete, good-looking grid inventory you can drop into any Unity project and ship. Everything works out of the box — press one menu button and you get a player bag, a wall of lootable chests, drag-and-drop, stacking, splitting, save/load and tooltips already wired up. Then swap in your own items and art.

Built on plain uGUI with clean, fully-commented C# source and a simple Model / Container / View split, it's easy to read, extend and bend to your game — RPG, survival, crafting, shooter or anything with a bag.

CORE INTERACTION

Drag and drop stacks within one grid or between any grids. Left-drag moves a whole stack, right-drag or right-click splits it in half, and Ctrl/Shift-drag peels off a single item. Matching stacks auto-merge and different items swap on drop. Double-click sends a stack straight to a linked grid (bag to chest and back). Every item has its own max stack size.

MULTI-CHEST LOOTING

A wall of chests that all open in one shared panel. Each chest keeps its own items and tints the panel to its color, so the player loots several chests from one window and drags loot straight into their bag. Add as many chests as you like.

READY-TO-SHIP POLISH

Save and load to PlayerPrefs or a JSON file (item id + count, resolved through an Item Database). One-click Sort consolidates stacks and orders by rarity. Hover tooltips show name, rarity, category, count and description. A 5-tier rarity system colors the slot borders, and a live "used / capacity" footer keeps count. Juicy animations throughout: hover scale, pop-on-land and a sort ripple.

THEMEABLE

Five built-in themes (Midnight, Emerald, Amber, Royal, Slate) let you swap the whole look in one click. Every color, size and spacing lives on a ScriptableObject Theme, so you can design and save your own.

ONE-CLICK SETUP

The Tools menu builds a themed, working demo instantly, plus menu items to create Inventory UIs, Themes and Items. No prefabs to wire, no scene surgery.

CLEAN, EXTENSIBLE CODE

A readable Model / Container / View architecture with a pure-C# inventory model that is UI-agnostic and easy to test. Events for slot and inventory changes let you hook weight, currency or quests. Full source included, no DLLs, no third-party dependencies.

WHAT'S INCLUDED

Complete inventory runtime and editor tools (C# source), a one-click demo scene (player + multi-chest), 5 theme presets, Item / Item Database / Theme assets, sample item icons and documentation.
