This tutorial shows how to build a modular inventory system in Unreal Engine 5 using Blueprints.
The system is designed to be reusable and production-ready, built with Actor Components, Blueprint Interfaces, and UMG. It works with the Third Person Template and can be adapted for RPG, survival, or top-down projects.
You will implement:
- Inventory data using Blueprint Structs
- A component-based system with add, remove, and stacking logic
- Modular pickup actors using Blueprint Interfaces
- Automatic pickup handling without hard references
- A UMG inventory UI using a grid layout
- Drop functionality with instant UI refresh
- Input-based inventory toggle with proper input mode handling
The tutorial is fully readable on its own, with the linked video provided as a visual walkthrough. The system is designed to scale and can be extended with features like stack limits, equipment slots, item effects, or drag-and-drop UI.
