Game Physics Cookbook
Discover over 100 easy-to-follow recipes to help you implement efficient game physics and collision detection in your games About This Book - Get a comprehensive coverage of techniques to create high performance collision detection in games - Learn the core mathematics concepts and physics involved in depicting collision detection for your games - Get a hands-on experience of building a rigid body physics engine Who This Book Is For This book is for beginner to intermediate game developers. You don't need to have a formal education in games-you can be a hobbyist or indie developer who started making games with Unity 3D. What You Will Learn - Implement fundamental maths so you can develop solid game physics - Use matrices to encode linear transformations - Know how to check geometric primitives for collisions - Build a Physics engine that can create realistic rigid body behavior - Understand advanced techniques, including the Separating Axis Theorem - Create physically accurate collision reactions - Explore spatial partitioning as an acceleration structure for collisions - Resolve rigid body collisions between primitive shapes In Detail Physics is really important for game programmers who want to add realism and functionality to their games. Collision detection in particular is a problem that affects all game developers, regardless of the platform, engine, or toolkit they use. This book will teach you the concepts and formulas behind collision detection. You will also be taught how to build a simple physics engine, where Rigid Body physics is the main focus, and learn about intersection algorithms for primitive shapes. You'll begin by building a strong foundation in mathematics that will be used throughout the book. We'll guide you through implementing 2D and 3D primitives and show you how to perform effective collision tests for them. We then pivot to one of the harder areas of game development-collision detection and resolution. Further on, you will learn what a Physics engine is, how to set up a game window, and how to implement rendering. We'll explore advanced physics topics such as constraint solving. You'll also find out how to implement a rudimentary physics engine, which you can use to build an Angry Birds type of game or a more advanced game. By the end of the book, you will have implemented all primitive and some advanced collision tests, and you will be able to read on geometry and linear Algebra formulas to take forward to your own games Style and approach Gain the necessary skills needed to build a Physics engine for your games through practical recipes, in an easy-to-read manner. Every topic explained in the book has clear, easy to understand code accompanying it.

C# Game Programming Cookbook for Unity 3D
An Accessible, Modular Style of Game Building—Easily Start Making Games with Unity 3D C# Game Programming Cookbook for Unity 3D presents a highly flexible core framework to create just about any type of game by plugging in different script components. Most scripts function within the game framework or in your own structures. The techniques and concepts discussed in the book give you a solid foundation in game development. The first ten chapters set up the flexible, reusable framework based in C# and suitable for all game types. The book also explains scripting of generic, reusable, and common functionality. The remainder of the text adds game-specific code to the framework to create four example games: a top-down arena shooter, a futuristic racing combat game, a tank arena deathmatch game, and a classic arcade-style vertical scrolling shoot ’em up. The games encompass artificial intelligence (path following, target chasing, and line-of-sight patrolling behaviors), game state control, wheel colliders, and weapon inventory management. The example files are available for download on the book’s CRC Press web page. Reducing your recoding, repurposing, or adaptation time, this book provides script-based components that you can use to jump start your own projects. The book’s modular components can be mixed and matched to build various kinds of video games for the Unity game engine.
