Ready to take your Flash knowledge to the next level? Then Macromedia Flash MX Advanced
for Windows and Macintosh: Visual QuickPro Guide is your ticket. Designed for professionals
like yourself-users who have mastered the basics of Flash but need help with the advanced
animation techniques and ActionScripting--this guide is a must-have for graphic designers,
Web animators, game programmers, interface designers, and multimedia pros.
In this volume, veteran Flash instructor Russell Chun eschews "cool effects" and case studies
for an approach that emphasizes methodology and problem-solving. Using the task-based
format that readers have come to expect from this popular series, Russell has divided the text
into three primary sections: animation, navigation, and interactivity. The guide covers all of
Flash’s new features, including the revamped user interface, brand-new commands, and added
drawing and text tools. Plus, you’ll find plenty of screen shots and visual aids to reinforce the
text. With Flash MX Advanced for Windows and Macintosh: Visual QuickPro Guide by your side,
you’ll soon find yourself thinking--maybe even dreaming--in Flash.

Introduction
Macromedia Flash MX is one of the hottest technologies on the Web today.
Leading corporate Web sites use its streamlined graphics to communicate their
brands; major motion picture studios promote theatrical releases with Flash
animations; and online gaming and educational sites provide rich user
experiences with Flash interactivity.
As a vector-based animation and authoring application, Flash is ideal for
creating high-impact, low-bandwidth Web sites incorporating animation, text,
video, and sound. With robust support for complex interactivity and server-side
communication, Flash is increasingly the solution for developing Internet
applications as well. From designer to programmer, Flash has become the tool
of choice for delivering dynamic content across various browsers and
platforms.
As the popularity of Flash increases, so does the demand for animators and
developers who know how to tap its power. This book is designed to help you
meet that challenge. Learn how to build complex animations, integrate
sophisticated interfaces and navigation schemes, and dynamically control
graphics, video, sound, and text. Experiment with the techniques discussed in
this book to create the compelling media that Flash makes possible. It’s not an
exaggeration to say that Flash is revolutionizing the Web. This book will help
you be a part of that revolution. So boot up your computer and get started.
Who Should Use This Book
This book is for the designers, animators, and developers who want to take
their Flash skills to the next level. You’ve mastered the basics of tweening and
are ready to move on to more complex tasks involving video, masking,
dynamic sound control, or movie-clip collision detection. You may not be a
hard-core programmer, but you’re ready to learn how ActionScript can control
graphics, sounds, and text. You’re ready to integrate interactivity with your
animations to create arcade-style games, to create complex user-interface
elements like pull-down menus, and to learn how Flash communicates with
outside applications such as Web browsers. If this description fits you, then
this book is right for you.
This book explores the advanced features of Flash MX, so you should already
be comfortable with the basic tools and commands for creating simple Flash
movies. You should know how to create and modify shapes and text with the
drawing tools and be able to create symbols. You should also know how to
apply motion and shape tweens, and how to work with frame-by-frame
animation. You should know your way around the Flash interface: how to move
from the Stage to symbol-editing mode to the Timeline, and how to manipulate
layers and frames. You should also be familiar with importing and using
bitmaps and sounds, and assigning basic actions to frames and buttons for
navigation. Review the tutorials that come with the software, or pick up a copy
of Macromedia Flash MX: Visual QuickStart Guide by Katherine Ulrich.
Goals of This Book
The aim of this book is to demonstrate the advanced features of Flash MX
through a logical approach, emphasizing how techniques are applied. You will
learn how techniques build on each other, and how groups of techniques can
be combined to solve a particular problem. Each example you work through
puts another skill under your belt, so by the end of this book you’ll be able to
create sophisticated interactive Flash projects.
For example, creating a pull-down menu illustrates how simple elements—
invisible buttons, event handlers, button-tracking options, and movie clips—
come together to make more complex behaviors. Examples illustrate the
practical application of techniques, and additional tips explain how to apply
these techniques in other contexts.
How to Use This Book
The concepts in this book build on each other, so the material at the end is
more complex than that at the beginning. If you’re familiar with some of the
material, you can skip around to the subjects that interest you, but you’ll find
it most useful to learn the techniques in the order in which they appear.
As with other books in the Visual QuickPro Guide series, tasks are presented
for you to do as you read about them, so that you can see how a technique is
applied. Follow the step-by-step instructions, look at the figures, and try them
on your computer. You’ll learn more by doing and by taking an active role in
experimenting with these exercises.
Tips follow the specific tasks to give you hints on how to use a shortcut,
warnings on common mistakes, and suggestions on how the technique can be
extended.
Occasionally, you’ll see sidebars in gray boxes. Sidebars discuss related
matters that are not directly task-oriented. You’ll find interesting and useful
concepts that can help you understand how Flash works.
What’s in This Book
This book is organized into five parts:
Part I: Approaching Advanced Animation
This part covers advanced techniques for graphics and animation,
including strategies for motion tweening, shape tweening, masking, and
using digital video and 3D graphics.
Part II: Understanding ActionScript
This part introduces ActionScript, the scripting language Flash uses to
add interactivity to a movie. You’ll learn the basic components of the
language and how to use the Actions panel to construct meaningful code.
Part III: Navigating Timelines and Communicating
This part teaches you the ways in which Flash can respond to input from
the viewer and how complex navigation schemes can be created with
multiple Timelines. You’ll also see how Flash communicates with external
files and applications such as Web browsers.
Part IV: Transforming Graphics and Sound
This part demonstrates how to dynamically control the basic elements of
any Flash movie—its graphics and sound— through ActionScript.
Part V: Working with Information
The last part focuses on how to retrieve, store, modify, and test
information to create complex Flash environments that can respond to
changing conditions.
Appendixes
Four appendixes give you quick access to the essential ActionScript
objects, actions, key code values, and events.
What’s on the CD
Accompanying this book is a CD-ROM that contains nearly all the Flash source
files for the tasks. You can see how each task was created, study the
ActionScript, or use the ActionScript to do further experimentation. You’ll also
find a trial version of Flash MX as well as a list of Web links to sites devoted to
Flash and showcasing the latest Flash examples, with tutorials, articles, and
advice.
Additional Resources
Use the Web to your advantage. There is a thriving international community of
Flash developers; within it you can share your frustrations, seek help, and
show off your latest Flash masterpiece. There are free bulletin boards and
mailing lists for all levels of Flash users. Begin your search for Flash resources
with the list of Web sites on the accompanying CD and with the Answers panel
in the Flash application, which provides links to the Flash developer community
on the Web.
