If you are an advanced Flash user, Extending Flash MX 2004 may be just the right book for you. Written by veteran Flash developers Keith Peters (bit-101) and Todd Yard (ego7), this book introduces you to the world of extending Flash MX 2004 by teaching you how to create custom functions and features for the Flash MX 2004 authoring environment.
At first I had never heard about 'Extending' Flash MX 2004, but hopefully my following explanation may help you to understand this concept if you are new to this term. Imagine Flash MX 2004 being a customizable browser such as Firefox. In Firefox, you can download snippets of programs called extensions that add some cool, extra features to your browser. Creating new extensions for Flash MX 2004 is similar to developing extensions for your browser. Using a new language called JavaScript Flash (JSFL), you have the ability to create scripts, commands, behaviors, etc. that add new functionality to not a Flash animation, but to your actual Flash MX 2004 application itself.
This book teaches you how to use JavaScript Flash to create extensions - custom commands, menu items, and others things to help make repetitive tasks easier and enhance your Flash MX 2004 program. You start with the basics and progress towards complicated techniques. Early on you start by creating a command that, for example, allows you to take any shape and automatically arrange them on a user-defined grid. Towards the end, you move beyond simple commands and learn how to modify Behaviors, create custom interfaces using XML, and more!
Another great feature of this book is the expansive JavaScript Flash (JSFL) reference. The JSFL reference section contains all of the various items of the JSFL language that you can refer to when creating your own JSFL extensions. For any JSFL code item or property, you will find a description, the types of values it accepts, and a code example.
If you use Flash MX 2004 extensively and are interested in automating some of the repetitive tasks or adding new, useful features to Flash, you will find this book's coverage of this new topic excellent for intermediate and advanced users.
