Build a complete, multiplayer-ready inventory system in Unreal Engine 5 using C++ and Blueprints. This course focuses on creating a spatial inventory with item grids, stackable items, equipment slots, and a modular item fragment system. You’ll code everything from scratch, ensuring your system is scalable and robust for any game project.
🎯 What you’ll learn
- Create and manage spatial inventory grids with item categories
- Code item interaction systems for picking up, dropping, and moving items
- Implement stackable, consumable, and equippable items
- Build a modular item fragment system for flexible item customization
- Develop multiplayer inventory and item systems for Listen Server and Dedicated Servers
✅ Requirements
- Skills: Knowledge of Unreal Engine C++ required
- Tools: Use of Rider IDE (free for non-commercial use)
- Hardware: Disk space for Unreal Engine 5 and debugging symbols
📝 Description
This course is all about building a spatial inventory system from the ground up in Unreal Engine 5. You’ll start by setting up a plugin, then move through creating item interaction, a grid-based UI, and multiplayer replication. The core of the system is an Item Fragment pattern—a modular way to give items different behaviors like stacking, consuming, or equipping. You’ll code everything in C++, with Blueprints used for UI and polish.
The inventory supports multiple categories (Equippable, Consumable, Craftable) and items of varying sizes that take up different grid squares. You’ll implement stackable items with max stack sizes, splitting, and combining. The equipment system lets you equip items like cloaks, masks, and weapons, with visual feedback on the character mesh. Everything is built for multiplayer, working on both Listen Server and Dedicated Servers.
You’ll also build a flexible tooltip system using the Composite Pattern, so item descriptions adapt based on what fragments an item has. The course provides all assets—3D meshes, textures, and Niagara effects—so you can focus on coding. By the end, you’ll have a reusable inventory plugin you can drop into any project.
🧑🎓 Who this course is for
- UE5 developers who want to implement inventory systems in their games
- Those who want to learn how items are handled in serious games
- Those who want to implement equipment systems
- Those who need multiplayer solutions to items, inventory, and equipment
