Powerful and continuing to grow, the mobile market has never been bigger and more demanding of great games. Android continues to prove itself as a strong contender in this challenging market. With Unity 3D, great games can be made for Android quickly and easily. With its great deployment system, the Android platform is now only one click away. Unity Android Game Development by Example Beginner's Guide dives straight into making real, fully-functional games, with hands-on examples and step-by-step instructions to give you a firm grounding in Unity 3D and Android. Everything necessary for creating a complete gaming experience is covered and detailed throughout the course of this book. Using clear and practical examples that progressively build upon each other, this book guides you through the process of creating games in Unity for Android. Start by learning about all the great features that Unity and Android have to offer. Next, create a Tic-Tac-Toe game while learning all about interfaces. After that, learn about meshes, materials, and animations with the creation of a tank battle game. You will then learn how to expand your game's environment with the addition of shadows and a skybox. Adding on this, you will also learn how to expand the tank battle by creating enemies and using path finding to chase the player. Next, explore touch and tilt controls with the creation of a space fighter game. Then, learn about physics while recreating the most popular mobile game on the market. You will then expand the space fighter game with the addition of all the special effects that make a game great. Finally, complete your experience by learning the optimization techniques required to keep your games running smoothly. While Unity is available for both Mac and Windows, the book is presented working from a Windows environment. Programming in Unity is possible in C#, JavaScript, and Boo. This book will be working in C# and the final projects will be provided in C# and JavaScript.

Time for action – steering the space ship


To steer our ship, we will need to create a single script and apply it to our ship:

  1. To start this off, create a new script and name it TiltSteering.

  2. As with all of our other scripts, we will begin this one with a few variables. The first two variables control the speed with which the ship will rotate as the device is tilted. The second two are going to be used to limit the rotation of the ship. These will determine how tight a circle the player's ship can turn in.

    public float horizRotateSpeed = 7f;
    public float vertRotateSpeed = 3f;
    
    public float horizMax = 60f;
    public float vertMax = 45f;
  3. Next, we will make use of the Update function. We start out by creating a variable to store the ship's current rotation. Next, we have to adjust the rotation. When working with Euler rotations, Unity adjusts values to be between zero and 360. This way, the values are never negative. Anything below zero simply wraps around and starts counting down from 360; anything...
