Advanced Inventory System for Unreal Engine 5

View Documentation Get Started

Core Systems

Everything you need to build complex inventory mechanics without reinventing the wheel

Grid & Slot Containers

Define Grid-Based (NxM Grid) and Slot-Based (Typed Slots) containers with tag-driven filters, access policies, rotation, and nesting support.

Item Definitions

Reusable UDataAsset definitions drive item identity, stacking, placement, equip rules, fragments, and cosmetics.

Operation Pipeline

Every mutation flows through Validate, Simulate, Commit, and Notify, with atomic handling for swap, split, merge, and batch operations.

Prediction-Aware

Server-Authoritative execution with Client Prediction, reconciliation, and authoritative correction when local simulation diverges.

Query & Views

Read-only View Structs and Query APIs expose stable snapshots for UI, Blueprint, tag searches, and placement previews.

Delta Replication

Flat registries and differential replication synchronize only changed data, reducing bandwidth and keeping multiplayer inventories scalable.
