I spent six months learning the fundamentals of Unreal Engine 5.
I learned the basics of utilizing blueprints, the landscape designer, decision trees, and many other systems. On top of that I spent a lot of my time researching all that the AI system can do.
I created many small projects to learn more about the engine and concluded with making a maze game where enemies chase you as you collect coins. I learned a lot in my tests of the engine and I plan to continue to make projects within Unreal Engine.
