This is a game changer in Unity!
Format: Paperback
The amazing part about this book is how it begins. It tells you which Unity, VS (Visual Studios), and which C# versions you should use for best results. This in my thoughts are the most important part when programming, know which ones to use to make your experience the best it can be.
There are exclusives in this as well. This book has some major pics to show those who are visual learners and that is a great asset as most people need to see it and use it in order to understand what they are doing. Books sometimes leaves this important thing and some get lost in the reading and put those types of books down and never pick them up again.
I read through this book and found things that intrigue me and make me want to literally just get into it until I'm done reading and using the pics to guide me through.
This book also works with MacOS as well. I'm not much into that operating system but I know many who prefer that and that is awesome that this teaches this way as well.
This even has pop quizzes for you to do to enhance the effects of learning and I am sure this would be a book that would be used in schools if it were offered as a preferred reading/teaching structuring the class for success.
I have said it before in my reviews that this is again another great book to add to your collection. Each book of this type is something that should be purchased or gifted to someone to make their lives easier when it comes to programming and the way this book does it's teaching style it makes programming that much easier and more fun.
So many things in this book I don't have enough room or a way of putting it into words. Best tog eab this book and enjoy every part of it and I promise it won't be a waste of money.

Great for getting into Unity and mastering it
Format: Paperback
Sometimes I mentor students who are just getting started in Unity. This is a great resource I can use to help them along.
The book has a great start by covering topics like what is a variable, how to call a function, classes, and OOP. There is even some tricks on how to debug your code which a lot of people struggle with. For statements this books covers all of them, if, else, for, switches, etc. Other books don't explain OOP well enough but with book goes over it very well and explains what the difference between a value and reference type is. Towards the end there are a bunch of project examples like making a player, shooting projectiles, and creating a user interface. This book is very up to date and uses Unity 6.
If you just started learning Unity then this is a must have book.

Code at your own pace to develop great games
Format: Paperback
Creating games isn’t intimidating thanks to this gem of a book. Easy to read and follow, the knowledgeable author makes learning C# fun and helps readers gain confidence, proving even a novice has what it takes to make a game. In addition, the author provides pop quizzes to ensure readers can measure their new-found knowledge before moving onto a new chapter. This hands-on approach is helpful and prevents readers from missing key components. Since my coursework never addressed connecting to the server and pulling data, I found chapter 13 to be of great interest and help. It was interesting to learn what happens behind the scenes and gave me valuable tools to explore, demonstrating this book is advantageous for both novices and professionals. There’s always something new to learn.

Well written and worth the price!
Format: Paperback
Learning C# by Developing Games with Unity 6 is an excellent resource for anyone looking to dive into game development while building a solid foundation in C#. Harrison Ferrone’s writing is clear, approachable, and well-structured, making complex concepts easy to understand—even for beginners. Even though this book is about learning C#, it also touches on game design, lighting and animation. I especially appreciated how the book balances coding fundamentals with Unity-specific techniques, creating a seamless learning experience. Whether you're new to programming or just new to Unity, this book is a fantastic starting point. Highly recommended for aspiring game developers!
