I’ve had a lot of requests for tutorials on game creation for the Android based phones and tablets. This will be my first (but not last!) tutorial.
I have two, 20 minute videos that take you through the process of creating a simple flight game.
You will need the Unity engine to follow along (http://unity3d.com). While the Android version of the software is expensive, you can do everything with the basic free version except publish to the actual device.
In part 1, I cover general setup and needed software to be able to publish to android devices. I also cover the first steps in setting up a game environment including skybox, and player.
In part 2, I cover the creation of the asteroids, bullets, prefabs, and use pre-existing scripts to add player control. I also cover the publish to the android device.
I would note that while this process was specific to publishing to an Android phone, everything would work exactly the same (minus the publishing) for an iPhone or iPad.
Note: The scripts used in the demonstration are all available from the StarTrooper example on the Unity site: http://unity3d.com/support/resources/tutorials/iphone-multiplayer-tutorial
