Overview of this book

Game development is a field of interdisciplinary skills, which also makes it a very complex topic in many respects. One decision that usually needs to be made at the beginning of a game development processis to define the kind of computer system or platform the game will be developed for. This does not pose any problems in general but as soon as the game should also be able to run on multiple platforms it will become a developer's nightmare to maintain several distinct copies of the same game. This is where the libGDX multi-platform game development framework comes to the rescue! "Learning Libgdx Game Development" is a practical, hands-on guide that provides you with all the information you need to know about the libGDX framework as well as game development in general so you can start developing your own games for multiple platforms. You will gradually acquire deeper knowledge of both, libGDX and game development while you work through twelve easy-to-follow chapters. "Learning Libgdx Game Development" will walk you through a complete game development cycle by creating an example game that is extended with new features over several chapters. These chapters handle specific topics such as organizing resources, managing game scenes and transitions, actors, a menu system, using an advanced physics engine and many more. The chapters are filled with screenshots and/or diagrams to facilitate comprehension. "Learning Libgdx Game Development" is the book for you if you want to learn how to write your game code once and run it on a multitude of platforms using libGDX.

The demo application – time for code

In this section we will take a closer look at the actual code of the demo project. Thereafter, we will do some simple modifications to the code and also use the debugger.

Inspecting an example code of the demo application

Let us take a first look at the generated code of from the demo project.

The following code listing shows the class definition:

public class MyDemo implements ApplicationListener {
  // ...

As you can see the MyDemo class implements the ApplicationListener interface. Before we move on to the implementation details of the interface, we will spend some time on the remaining part of this class.

You will find a definition of four member variables, each with a class provided by Libgdx.

private OrthographicCamera camera;
private SpriteBatch batch;
private Texture texture;
private Sprite sprite;

Here is a brief explanation of the classes from the preceding code listing to give you a basic background knowledge for the code inspection that...
