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.

Setting a custom Android application icon

First we want to replace the default launcher icon that came with the generated Canyon Bunny Android project. There is a special directory called res that resides in the Android CanyonBunny-android project. It contains resource files that are exclusively available to the Android application.

You should see the following three folders starting with "drawable" in names:

  • drawable-ldpi (low density screen)

  • drawable-mdpi (medium density screen)

  • drawable-hdpi (high density screen)

These folders are used by Android to support different screen sizes and resolutions resulting in different screen densities. For the sake of simplicity, we will ignore the whole topic of screen support and create a special common folder called drawable. Android will use the contents of this folder regardless of the screen density detected.

The following screenshot shows the default launcher icon called ic_launcher.png that our application is currently using:

Now, delete all three...
