The Master Inventory Engine – Crafting/Loot/Trade/Skills/HotBar v2.2 (19 Jun 2025) is a versatile Unity package designed to streamline the development of rich inventory, crafting, and trade systems. It offers a developer-friendly interface that enables quick setup and customization of inventory, crafting, and trade mechanics. The system includes robust crafting, enhancing, socketing, and enchanting features, allowing players to create and customize powerful items. A dynamic skill system lets developers define and organize skills by class or type, with seamless integration into the hot bar for intuitive gameplay. The package is optimized for rogue-like games with randomized item stats, dynamic loot generation, cooldowns, and attribute restrictions to enhance strategic depth. Loot packs can be configured with customizable drop rates, item pools, and random enchantments. A fully customizable NPC system allows NPCs to function as merchants with dynamic pricing and unique inventories, including two interface styles: simple drag-and-drop and DOS2-style. NPCs can also have their own equipment and inventories, with support for assigning them to perform crafting tasks. The UI is highly customizable, supporting various art styles (including pixel art), color adjustments, and feature toggling to match game aesthetics. An extensible tags and commands system enables integration with quests, building mechanics, and other game systems. The package includes an extensive asset library with over 80 equipment icons, 200 item icons, 30 NPC avatars, and 20 skill icons. It features an auto-save/load system with manual save support via a single line of code and full modding support through JSON import/export for items, attributes, and enchantments. Comprehensive documentation, including a 40-page PDF guide, ensures developers can quickly get started and maximize the system’s capabilities.
