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.

So far, we have only used the AndEngine class, PhysicsFactory, to create rectangle (box) bodies. It is the simplest and most straightforward way to create bodies. The whole creation of a body remains hidden.

A body consists of one or more fixtures. Let's create a slightly more complicated body by manually creating three fixtures and putting them together to form a body. We will first create fixtures for the head, torso, and body, just to illustrate how to create multiple fixtures, but we are going to see how filtering works on the example of these fixtures as well.


There are more ways of creating fixtures. One of the more automated ways is to use an external editor such as R.U.B.E. and a loader that will load the data to AndEngine. However, such a loader exists only as an unofficial extension.

Here's a screenshot showing how the final body should look in the game:
