Foundation ActionScript Animation:
Making Things Move!
lash has long been one of the most approachable, user-friendly tools for creating
Fweb-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 e
more powerful and a little plex, too. ActionScript, now at version , 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 . First, all the basics of script-based animation and setting
up an ActionScript project are covered. An introduction to object-oriented
programming follows, with the new syntax, events, and rendering techniques of
ActionScript explained, giving you the confidence to use the language, whether
starting from scratch or moving up from ActionScript .
The book goes on to provide information on all the relevant trigonometr
