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.

Animating the menu screen

Let us now discuss what we are actually going to animate in the menu screen. Basically, the first two bits of our animated menu involve the gold coins and the large bunny head.

Take a look at the following screenshot:

In this screenshot you can see a rough sketch of the final animation divided in to four essential steps. The following lists the actions that need to be taken for the shown steps:

  1. The gold coins and bunny head are invisible at the beginning.

  2. The gold coins fade in and scale up from 0 percent to 100 percent from the center screen as if they are jumping out of the water.

  3. After a short pause, the bunny head appears in the top-right corner which moves slightly until it reaches the edge of the rock that is visible in the background.

  4. The bunny head moves as if it was jumping over to the other rock in front of it.
