I am using this opportunity to thank God for giving me talent and a wonderful
family, who are my real inspiration. I am grateful to them for their aspiring guidance
and continuous support while writing this book. I am thankful to Epic Games for
giving out such an amazing Engine to the world for free! You guys are the best!
I express my warm thanks to my fiancée Gale Fernandes; without her amazing
support and constructive criticism, this book possibly would not have happened.
I would also like to thank my brother Rakesh PV for introducing me to the world
of games and game technologies. It is through him I learned everything related to
games and I am proud to say that he is my first mentor.
I wish to extend my deep thanks and gratitude to my good friends Alexander
Paschall (Epic Games) and Chance Ivey (Epic Games) and also to my best friend
Reni Dev, with whom I created my first game.
I also wish to thank my dear friend and C++ mentor, Nathan Iyer (Rama) for his
great support. With his amazing articles and examples on C++, he has taught many
(including me) in the Unreal Community. He was kind enough to review my C++
chapter, point out mistakes and gave honest feedbacks including spending his
valuable time to remove some technical discrepancies. Thank you so much Rama!

Finally, I would like to thank Vasundhara Devi and Lucy Fernandes for giving me all
those joyous moments that put a smile on my face. Thank you moms! I love you.
