Unreal Engine - Generic Inventory System

Updated: May 28, 2025
System Overview
The Generic Inventory System(GIS) is a powerful, flexible, and easy-to-integrate framework for inventory based systems.
The system is designed to be modular and scalable, allowing complex inventory structures to be created quickly. It can also be used as the basis for other systems.
Many people will think of building or farming as separate systems, when in fact a good inventory system can allow these type of systems to be built on top of it, because they are essentially resource management, just in a somewhat different form on the surface.
It will help developers save time and cost greatly and give you the flexibility to build a variety of inventory systems that meet your needs. Looking forward to your use!
Features:
- data-driven: add new items through item definitions and manage them as DataAsset.
- Simple API: Through a simple but powerful API, you can easily add, delete, modify and query item instances from inventory.
- Attribute System: Using GameplayTags in UE to complete the attribute system. You can add default attributes to item definitions, and item instances will hold attribute states. You only need to configure in the editor, no code.
- MVC architecture: item definition is Model, item instance is Controller, Actor or UI with physical performance is View.
- Crafting and Enhancement: You can flexibly define the crafting recipe and enhancement logic according to the game requirements, providing players with more game fun and challenges.
- Equipment System: Independent from the item system, but can be used in conjunction with the item system. It is very suitable for managing attachments, weapons, talismans and so on.
- Network Support: This plugin supports multiplayer network environment. It works perfectly with UE5's multiplayer networking system for a seamless multiplayer experience. You can easily synchronise inventory and transaction information between multiple players, providing players with richer interaction experience.
- Store/Load: Item instances allow you to persist the data of the items themselves and save/load via a simple API.
You don't need to master C++ to use this system. GIS is very blueprint friendly and developers can also extend it with blueprints and C++.
