A modular, server-authoritative inventory and equipment framework for Unreal Engine. Blueprint-friendly, C++-extensible, and built so nothing is hard-coded.
WHAT YOU GET
• Data-driven items: each item is a Data Asset built from reusable fragments (weight, stacking, icon, consumable, durability, economy, world visuals, equipment)
• Inventory rules: weight limit, slot capacity, item filters, slot-grid layout and Tetris-style spatial layout. Combine them or write your own
• Equipment manager: named equipment points, wield, stow and swap, queued actions with animations, attachments and conflict handling
• World items: pickup actors with physics, impact effects, damage and visuals driven by the item asset
• Gameplay actions: collect, drop, consume, loot, transfer, craft/purchase and dismantle
• Multiplayer: server authoritative, Fast Array replication, client prediction helpers, access and distance checks, request limits
• Saving: inventories, equipment and world items, with a versioned save format
• Ready-made UI: CommonUI-based grid, spatial and equipment-slot widgets with drag and drop between inventories
• Per-item runtime data: durability, level, stats, attributes, marks, ammunition (extendable)
BUILT FOR DEVELOPERS
• Blueprint and C++ APIs, full source code
• Extend with your own fragments, item data, rules, actions, widgets, and world-item actors
• Native gameplay tags and types are exported, so your C++ game module links cleanly
• Documentation: setup, concepts, multiplayer, saving, extending, troubleshooting
