Decision-making with Behavior Trees (chapters 2, 6, 8, 9, and 10)

Once the agent can perceived the world around it, it needs to start making decisions, which have consequences. Some decision-making processes might become so complicated that the agent needs to come up with a proper plan to successfully achieve a goal.

The built-in Unreal Engine framework for AI rotates around Behavior Trees, which occupy a significant part of this book. Of course, this doesn't preclude the possibility to implement other AI systems on your own for decision-making in Unreal, but, by choosing Behavior Trees, you will have a strong set of tools ready to go, which we will explore in detail in this book.
