Mastering AndEngine Game Development

By: Maya Posch

Overview of this book

AndEngine is a popular and easy-to-use game framework, best suited for Android game development. After learning the basics of creating an Android game using AndEngine it's time you move beyond the basics to explore further. For this you need to understand the theory behind many of the technologies AndEngine uses. This book aims to provide all the skills and tools you need to learn more about Android game development using AndEngine. With this book you will get a quick overview of the basics of AndEngine and Android application development. From there, you will learn how to use 3D models in a 2D scene, render a visual representation of a scene's objects, and create interaction between these objects. You will explore frame-based animations and learn to use skeletal animations. As the book progresses, you will be guided through exploring all the relevant aspects of rendering graphics with OpenGL ES, generating audio using OpenSL ES and OpenAL, making the best use of Android's network API, implementing anti-aliasing algorithms, shaders, dynamic lighting and much more. With all this, you will be ready to enhance the look and feel of your game with its user interface, sound effects and background music. After an in-depth study of 2D and 3D worlds and multi-player implementations, you will be a master in AndEngine and Android game development.

Importing a model


The Assimp library provides conversion tools for reading resource files, such as those for 3D mesh models, and provides a generic format on the application's side. For a 3D mesh file, Assimp provides us with an aiScene object that contains all the meshes and related data as described by the imported file.

After importing a model, we need to read the sets of data that we require for rendering. These are the types of data:

  • Vertices (positions)

  • Normals

  • Texture mapping (UV)

  • Indices

Vertices might be obvious; they are the positions of points between which lines of basic geometric shapes are drawn. Usually, three vertices are used to form a triangular face, which forms the basic shape unit for a model.

Normals indicate the orientation of the vertex. We have one normal per vertex.

Texture mapping is provided using so-called UV coordinates. Each vertex has a UV coordinate if texture mapping information is provided with the model.

Finally, indices are values provided per face, indicating...
