Learn how to configure character behaviour systems from scratch. This Unreal Engine tutorial breaks down the essential anatomy of State Trees, providing a clear alternative to traditional behaviour trees. If you are building modular systems or working with tools like the OpenCage mod toolkit, understanding this logic structure is critical for scalable projects. We focus on the practical configuration steps required to set up these trees for character behaviour. By the end, you will have a functional framework for managing game logic that keeps your blueprints organised and performant.
