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.

Chapter 4. HUD and Text Display

In this chapter, we will learn about text output. We will look deeper into how fonts are created and stored and analyze the possible problems of AndEngine's way of displaying text characters. We will also learn how to create multilingual games and how to localize them.

We will see how to put text on a screen utilizing a heads-up display (HUD) in order to display the score of the game. Alternative ways of displaying text messages will also be discussed.

Finally, we will cover the basics of Android and AndEngine logging and debugging output.
