Quick Inventory Pro - Inventory System

Quick Inventory Pro is a complete, visually polished grid inventory designed to drop directly into any Unity project. It operates out of the box with integrated player bags, lootable chests, drag-and-drop controls, stacking, splitting, save-load functionality, and tooltips. Users can quickly swap in custom items and artwork. Interactions include moving whole stacks with left-click dragging, splitting stacks via right-click drag or click, peeling off single items with keyboard modifiers, and double-clicking to transfer between grids. Matching stacks merge automatically while mismatched ones swap positions. Multi-chest functionality allows players to loot several containers through a single shared panel, with each chest tinting the interface and retaining independent inventory data. Polish features include saving to PlayerPrefs or JSON files, automated sorting by rarity, detailed hover tooltips, a five-tier color-coded rarity system, and lively hover and placement animations. Five built-in themes allow instant visual swaps, with all styling managed through ScriptableObject assets for easy customization. Setup requires only a menu tool to generate working demo UIs without manual prefab wiring or scene editing. The underlying architecture follows a clean Model-Container-View pattern in pure C#, keeping the inventory logic UI-agnostic and event-driven for easy integration with weight systems, currencies, or quests. Includes full source code, editor tools, demo scene, preset themes, database assets, sample icons, and comprehensive documentation.
