To get the most out of this book

For this book, you only need to install a recent version of Unity3D. The code projects in this book have been tested on macOS and Windows on Unity 2022 and Unity 2021 but, with minor adjustments, they should work with future releases too.

For Chapter 9, Behavior Trees, you will need to install the Behavior Bricks plugin for Unity. In Chapter 11, Machine Learning in Unity, we will install Python 3.7 and PyTorch.

If you are using the digital version of this book, we advise you to type the code yourself or access the code from the book's GitHub repository (a link is available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.
