To get the most out of this book

The main requirement for this book is having Unity Version 2018.2 or higher installed. In Chapter 9, Behavior Trees, we download Behavior Bricks, a free Behavior Tree plugin, which requires an account with the Unity Store. In Chapter 10, Machine Learning, we will use Unity's Machine Learning for Agents Toolkit, an official machine learning platform based on TensorFlow. For this reason, that chapter requires Python 3.6 to be installed.
