Design Patterns are powerful tools for the creation of robust and scalable software. Presented one by one, patterns are easy to understand, even for a beginner. However, using and combining them in a complex application is much more difficult.In this book, we focus on the creation of video games: a complete example game and our own game. During the presentation of these developments, we see concepts from the most simple to the most complex. We start with the basics of data representation and elements of graphic user interfaces. In this scope, we make use of popular patterns. Then, we see more advanced patterns for the design of the video game engine. At this step, we create combinations of existing patterns and techniques to solve all problems. To succeed, the software architect has to develop skills in design that lead to new patterns dedicated to its current project. This work continues with even more advanced cases with the implementation of artificial intelligence and network gaming.Only basic knowledge of object programming is required to start reading this book. A complete game example, divided into many sub-steps, is provided with this book. Beginners can use parts of the game example to create their game, and more experimented programmers can work from scratch.More details on https: //www.patternsgameprog.com/boo
