In this video I walk you through setting up an inventory system in Unreal Engine 5.6 using Ninja Bear Studios’ Ninja Inventory plugin. I start from the very beginning—enabling the plugin, organizing an Inventory folder, and configuring the Asset Manager so UE scans for both Inventory Container Data Assets and Inventory Item Data Assets. Then I set up the core runtime pieces the “Ninja way”: I put the Inventory Manager on my Player State for replication (so multiple players can interact with the same chest, pickups, and dropped items), and I implement the Inventory System Interface so anything with an inventory can properly expose its manager. After that, I add the Equipment Manager to the character and implement the Equipment System Interface, then I build a simple pickup workflow: a Ninja Inventory Pickup Actor that points to an Item Definition (Item Data Asset). I show how item “fragments” make items modular—UI, stack/quantity, placement tags, quality/rarity, equipment states, economy, encumbrance, and even grid dimensions if you want a Diablo-style layout. To drive container slot counts, I import Ninja’s Inventory Attributes JSON, wire it into my GAS default attributes, and bind my container layout to the Backpack Slots attribute. Finally, I create the UI widgets (item + container) using Ninja’s view models and resolver setup, including a small function to set the item icon cleanly when it’s valid.
