Foundation Actionscript 3.0 Animation:
Making Things Move!

By Keith Peters

In this book, you'll learn

• All the ActionScript 3.0 (including math and trigonometry functions) and Flash rendering techniques you'll need to start animating with code
• Basic motion principles such as velocity, acceleration, friction, easing, and bouncing
• How to handle user interaction via the keyboard and mouse
• Advanced motion techniques such as springs, coordinate rotation, conservation of momentum, and forward and inverse kinematics
• All the basic 3D concepts you need to do 3D in Flash, from simple perspective to full 3D solids complete with backface culling and dynamic lighting

Flash has long been one of the most approachable, user-friendly tools for creating web-based animations, games, and applications. This has contributed to making it one of the most widely used programs for creating interactive web content. With each new version of Flash, ActionScript, its built-in scripting language, has become more powerful and a little more complex, too. ActionScript, now at version 3.0, has significantly matured as a programming language, bringing power and speed only previously dreamed about to Flash-based animation, going far beyond traditionally used keyframes and tweens.

The material inside this book covers everything you need to know to harness the power of ActionScript 3.0. First, all the basics of script-based animation and setting up an ActionScript 3.0 project are covered. An introduction to object-oriented programming follows, with the new syntax, events, and rendering techniques of ActionScript 3.0 explained, giving you the confidence to use the language, whether starting from scratch or moving up from ActionScript 2.0.

The book goes on to provide information on all the relevant trigonometry you will need, before moving on to physics concepts such as acceleration, velocity, easing, springs, collision detection, conservation of momentum, 3D, and forward and inverse kinematics. In no time at all you'll both understand the concepts of scripted animation and have the ability to create all manner of exciting animations and games.

This book is part of friends of ED's 'Foundation' series

The Foundation series is perfect for beginners to a technology, because it doesn't assume any previous knowledge. Each book in the series takes you step by step through your chosen technology, starting with the absolute fundamentals and working through all aspects of the technology, ultimately providing you with a firm grasp of the basics that will enable you to create your own applications or web sites. You will learn by following complete examples at every stage of your journey, often by extended case studies that you will build upon throughout the book. The Foundation series will give you the broad and solid base you need in order to progress to a higher level of expertise.
