Overview of this book

Smartphones and tablets have really changed the technological landscape over the last 3-4 years. Much like the web did in the last decade, these powerful tools have changed the way people communicate and access information. Such a wide market creates opportunities for developers who have the skills to develop mobile applications. "Creating Mobile Apps with Appcelerator Titanium" is a practical, step-by-step guide to building iPhone, iPad, and Android applications using JavaScript. This book will give you a solid grounding of the dos and don'ts of mobile development and also covers a lot of the functionalities offered by the Titanium platform. This book begins with a look at what the Titanium platform has to offer. By taking you through clear tutorials on developing each application step-by-step, it helps you to apply your newly acquired knowledge afterwards. The difficulty level gradually increases along the course of the book. Each application from this book covers different aspects of mobile development. Every chapter starts by defining the application's features as well as the user interface structure. Every single code section is then explained and put into context allowing you to gain a clear understanding of their purpose and functionality. The book takes a “small milestone” approach, allowing you to actually run the application and see the progression. Every step is accompanied by many screenshots so you can see the expected result on screen. You will learn everything you need to know to develop your very own mobile applications. The book takes a laid-back approach to Titanium development and provides information in a way designed to never overwhelm the reader with information and also uses clear diagrams, screenshots, and tips throughout.

Every game needs a hero and our game will be no exception to this rule. The first order of business will be to determine how he will look like on the screen. We want the hero to be able to face all the four directions when moving around the map, and we want him to have a walking animation when he is moving.

Hold that code, will you?

Just as we did with the map, we will need to have a graphical representation of our hero. Not only that, we will need a drawing for each direction to which our hero is facing as well as every frame of his walking animation.

To do this, we could use one image for every position at which our hero will appear in the game world, but a better approach will be to use a SpriteSheet. Much like a tileset, a SpriteSheet is basically an image containing all the images which we will need to display our hero at any given time.

There are a lot of free SpriteSheet that we can use. For our game, we will be using one made by a gentleman named Sith Jester. He has a...
