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 Box2D Debug Draw extension

When working with simple physics, one can easily imagine how the bodies look and where the collisions happen. However, with added complexity, when a problem arises, it is almost impossible to find out where it lies without visual aid. This is where the Debug Draw extension comes in. Most of the Box2D ports will have a functionality to visualize the bodies using outlines and colors.

Such a visualization typically looks something like this:

Adding Debug Draw to our AndEngine project

AndEngine has a Debug Draw extension as well. It was created by Nazgee, an AndEngine user and game programmer. It is an unofficial extension, but it works very well. It can be downloaded and added to any AndEngine project using the same method described in the Downloading the sources and Adding AndEngine to Eclipse IDE sections of Chapter 1, Setting Up an AndEngine Project, for the Box2D Physics Extension.
