About the Author
Francesco Sapio obtained his computer science and controls engineering degree from
Sapienza University of Rome, Italy, with a couple of semesters in advance, graduating
summa cum laude; he is currently studying there for a master's of science and engineering
degree in artificial intelligence and robotics.
He is a Unity 3D and Unreal expert, skilled game designer, and experienced user of major
graphics programs. He developed Game@School (Sapienza University of Rome), an
educational game for high-school students to learn concepts of physics, and the Sticker
Book series (Dataware Games), a cross-platform series of games for kids. In addition, he
worked as consultant for the (successfully funded by Kickstarter) game Prosperity – Italy
1434 (Entertainment Game Apps, Inc) and for the open online collaborative ideation system
titled Innovoice (Sapienza University of Rome). Moreover, he has been involved in different
research projects such as Belief-Driven Pathfinding (Sapienza University of Rome), which is a
new technique of path finding in video games that was presented as a paper at the DiGRA-
FDG Conference 2016; and perfekt.ID (Royal Melbourne Institute of Technology), which
included developing a recommendation system for games.
Francesco is an active writer on the topic of game development. Recently, he authored the
book Unity UI Cookbook, Packt Publishing. It teaches readers how to develop exciting and
practical user interfaces for games within Unity, and he wrote a short e-guide, What do you
need to know about Unity, Packt Publishing. In addition, he co-authored the book Unity 5.x
2D Game Development Blueprints, Packt Publishing, which has also been transformed in the
video course Unity 5.x Game Development Projects, Pack Publishing. He has also been a
reviewer for the following books: Game Physics Cookbook, Packt Publishing, Unity 5.x by
Example, Packt Publishing, and Unity Game Development Scripting, Packt Publishing.
Francesco is also a musician and a composer, especially of soundtracks for short films and
video games. For several years, he worked as an actor and dancer, where he was a guest of
honor at the Teatro Brancaccio in Rome. In addition, he has volunteered as a children's
entertainer at the Associazione Culturale Torraccia in Rome. Finally, Francesco loves math,
philosophy, logic, and puzzle solving, but most of all, creating video games—thanks to his
passion for game designing and programming.

Acknowledgment
I'm deeply thankful to my parents for their infinite patience, enthusiasm, and support
throughout my life. Moreover, I'm thankful to the rest of my family, in particular to my
grandparents, since they have always encouraged me to do better in my life with the Latin
expressions Ad maiora and Per aspera ad astra.
I also want to thank Lauren S. Ferro, the reviewer, for her fantastic feedback and help,
which have enhanced the quality of this book. Another important person, without whom
this book couldn't have seen the light, is Mayur Pawanikar, the content development editor,
who supported me throughout the whole process.
Finally, a huge thank to all the special people around me whom I love. In particular to my
girlfriend: I'm grateful for all of your help in everything, I love you.
