Leverage the power of LibGDX to create a fully functional, customizable RPG game for your own commercial title About This Book Learn game architecture and design patterns with concrete examples using proper software engineering principles Save time and money with this handy reference guide for future game development with LibGDX Design and develop a fully functional RPG video game from scratch with a hands on, step-by-step approach using LibGDX Who This Book Is For If you are an intermediate-level game developer who wants to create an RPG video game but found the creation process overwhelming, either by lack of tutorials or by getting lost in a sea of game-related technologies, engines, or frameworks, then this book is for you. This book assumes familiarity with Java and some basic knowledge of LibGDX. What You Will Learn Develop characters with stat attributes, player movement, animation, physics, and collision detection Create interactive NPC characters with speech windows and build immersion via dialog trees Build inventory management system UIs with drag and drop items to sell, buy, and equip Design a quest system to expand out the content of your game Form interesting enemies with battle mechanics and spawn points Devise *ed cutscenes to add an element of story and drama Develop save and load game profiles Create special effects to give the game extra “juiciness” and polish, and help build the atmosphere In Detail LibGDX is a Java-based framework developed with a heavy emphasis on performance, and includes cross-platform support out of the box (Windows, OS X, Linux, iOS, Android, and HTML5) as well as providing all the low-level functionality so that you can focus on developing your game and not battling with the platform. LibGDX also has an engaged and responsive community, active maintenance, and is available for free without a prohibitive license. Starting from the beginning, this book will take you through the entire development process of creating an RPG video game using LibGDX. First, this book will introduce you to the features specific to RPG games, as well as an overview of game architecture. Then, you will create map locations, develop character movement, add animation, integrate collision detection, and develop a portal system. Next, you will learn and develop a HUD and other UI components, as well as an inventory management system. You will then develop NPC interactions including dialog trees, shopkeepers, and quest givers. After this, you will design and create battle features for fighting enemies, as well as event triggers for world events. Finally, you will add the final polish with sound, music, and lighting effects. By the end of this book, you will have learned and applied core components from the LibGDX framework, as well as have a finished game to use as a springboard for customization and story development for your own commercial video game. Style and approach This book walks you through the concepts and implementation of developing a complete RPG game, unfolding chapter by chapter and building upon previous concepts. Each chapter can be used as an individual reference with diagrams to explain core concepts with concrete example code explained in detail.

The Amazing Maurice and His Educated Rodents
The Amazing Maurice and His Educated Rodents
Pratchett, Terry
¥50.33
One rat, popping up here and there, squeaking loudly, and taking a bath in the cream, could be a plague all by himself. After a few days of this, it was amazing how glad people were to see the kid with his magical rat pipe. And they were amazing when the rats followed hint out of town. They'd have been really amazed if they'd ever found out that the rats and the piper met up with a cat somewhere outside of town and solemnly counted out the money. The Amazing Maurice runs the perfect Pied Piper scam. This streetwise alley cat knows the value of cold, hard cash and can talk his way into and out of anything. But when Maurice and his cohorts decide to con the town of Bad Blinitz, it will take more than fast talking to survive the danger that awaits. For this is a town where food is scarce and rats are hated, where cellars are lined with deadly traps, and where a terrifying evil lurks beneath the hunger-stricken streets.... Set in Terry Pratchett's widely popular Discworld, this masterfully crafted, gripping read is both compelling and funny. When one of the world's most acclaimed fantasy writers turns a classic fairy tale on its head, no one will ever look at the Pied Piper -- or rats -- the same way again!

The murals in restaurants are on a par with the food in museums. America is an enormous frosted cupcake in the middle of millions of starving people. Critics are like pigs at the pastry cart.

Throughout history, many masters of metaphor have crafted observations that are so spectacular they have taken up a permanent residence in our minds. In I Never Metaphor I Didn't Like , quotation maven Dr. Mardy Grothe fixes his attention on the three superstars of figurative language analogies, metaphors, and similes. The result is an extraordinary compilation of nearly 2,000 feats of association that will entertain, educate, and occasionally inspire quotation lovers everywhere.

Power
Pfeffer, Jeffrey
¥168.37
In this crowning achievement, one of the greatest minds in management theory reveals how to succeed and wield power in the real world. Over decades of consulting with corporations and teaching MBA students the nuances of organizational power, Jeffrey Pfeffer has watched numerous people suffer career reversals even as others prevail despite the odds. Our most common mistake is not having a realistic understanding of what makes some people more successful than others. By believing that life is fair, we tend to subscribe to the “just-world phenomenon,” which leaves us unprepared for the challenges and competition of the real world. Now Pfeffer brings decades of his incredible insights to a wider audience. Brimming with counterintuitive advice, numerous examples from various countries, and surprising findings based on his research, this groundbreaking guide reveals the strategies and tactics that separate the winners from the losers. Power, he argues, is a force that can be used and harnessed not only for individual gain but also for the benefit of organizations and society. Power, however, is not something that can be learned from those in charge their advice often puts a rosy spin on their ascent and focuses on what should have worked, rather than what actually did. Instead, Pfeffer reveals the true paths to power and career success. Iconoclastic and grounded in the realpolitik of human interaction, Power is an essential organizational survival manual and a new standard in the field of leadership and management.
