Ninja Inventory
The Ninja Inventory plugin was inspired by concepts introduced by Epic's project "Lyra", such as definitions, instances, and fragments. These concepts are quite powerful for an inventory system, as they promote defining items through aggregation instead of the classic inheritance approach.
For a generic and reusable framework like this, such concepts are fundamental, as they truly allow the Inventory System to remain agnostic of a game's design and requirements. Furthermore, in line with a recurring theme for all plugins from Ninja Bear Studio, this framework was designed with a strong focus on separation of concerns.
This is an ample and advanced system, built on top of many Unreal Engine capabilities. To take full advantage of it, it's recommended that you have some familiarity with these base systems. For advanced usage, you will need to use C++.
Main Features

Design Pillars
Separation of Concerns: The Inventory domain is self-contained and affect other domains such as "Locomotion", "Combat", "Interaction", etc.
Flexibility: The Inventory System is flexible enough to be used in multiple projects, from simple weapon wheels to RPG games.
Extensibility: Multiple extension points are available so the Inventory System can be adapted to many situations.
Designer Friendly: You can configure and operate the entire Inventory System using Data Assets and Blueprints. Deeper customization might require C++.
Engine Parity: As much as possible, reuses features already available in the engine, without "reinventing the wheel".
Integrations
