Learning AndEngine

By: Martin Varga

Overview of this book

AndEngine is a very popular open source OpenGL (open graphics library) Android game engine, used to create mobile games quickly while maintaining the ability to fully customize them. This book will guide you through the whole development process of creating a mobile game for the Android platform using one of the most popular and easy-to-use game engines available today. Beginning with the very basics, you will learn how to install AndEngine, gather graphics, add sound and music assets, and design game rules. You will first design an example game and enhance it by adding various features over the course of the book. Each chapter adds more colors, enhances the game, and takes it to the next level. You will also learn how to work with Box2D, a popular 2D physics engine that forms an integral part of some of the most successful mobile games. By the end of the book, you will be able to create a complete, interactive, and fully featured mobile game for Android and publish it to Google Play.

The physics engine

AndEngine uses the Android port of the Box2D physics engine. Box2D is very popular in games, including the most popular ones such as Angry Birds, and many game engines and frameworks use Box2D to simulate physics. It is free, open source, and written in C++, and it is available on multiple platforms. AndEngine offers a Java wrapper API for the C++ Box2D backend, and therefore, no prior C++ knowledge is required to use it.

Box2D can simulate 2D rigid bodies. A rigid body is a simplification of a solid body with no deformations. Such objects do not exist in reality, but if we limit the bodies to those moving much slower than the speed of light, we can say that solid bodies are also rigid.

Box2D uses real-world units and works with physics terms. A position in a scene in AndEngine is defined in pixel coordinates, whereas in Box2D, it is defined in meters. AndEngine uses a pixel to meter conversion ratio. The default value is 32 pixels per meter.
