The Ninja Factions plugin extends the AI Module's domain, introducing the concept of Factions, Memberships and Reputation.

It's designed to be simple enough so it's easy to get started, only requiring an Actor Component to be added to Faction Members and creating the Faction Data Assets with their accompanying Reputation Data Tables (optional).

The system uses the Asset Manager as its default Faction Database, but you can create your own Database, such as a "Backend Server" for example. The Attitude between Factions is also defined by a dedicated class type named Attitude Solvers, and you can decide to use the ones provided or, like the Database, create your own.

All these design choices were made to ensure the system is both very usable right away, but highly customizable and easily integrated with other systems.

This plugin was written in C++, but everything is available to Blueprints. The code is clean and well-documented, it has a thorough on-line documentation and you are welcome to join the Discord Server!
