Building an Inventory System in Unreal Engine 5: Data Assets, Components & Multiplayer

Welcome to a new episode of The Game Dev Blueprint Podcast! In this episode, we dive into one of the most common systems found in games: the Inventory System. We explain how beginners can build a modular inventory in Unreal Engine 5, starting with drag-and-drop UI and gradually moving into more scalable systems using Actor Components, Data Assets, Soft References, multiplayer replication, and Save/Load systems. You'll learn: How to create a basic inventory system in Unreal Engine 5 Setting up drag-and-drop inventory slots with Widget Blueprints Building modular inventory logic using Actor Components Why component-based composition can be more flexible than traditional inheritance The "secret power" of Data Assets for managing items Organizing item data to make designer workflows faster Using Soft Object Pointers/Soft References to reduce unnecessary memory usage Creating modular item systems that can scale with your game Connecting inventory systems with the Gameplay Ability System Saving inventory and item data across multiple game sessions Replicating inventory state correctly in multiplayer Understanding server-authoritative inventory logic Preventing inventory desync and multiplayer item duplication issues Practical approaches for building an inventory that can grow from a prototype into a larger production system Whether you're creating an RPG, survival game, multiplayer experience, or your first Unreal Engine project, this episode provides a practical foundation for designing an inventory system that is modular, scalable, and multiplayer-ready.
