{Book Description}
This book is the 2nd edition of Keith Peters' best-selling ActionScript animation book, updated to ActionScript 3.0all of the code has been updated, and some new techniques have been added to take advantage of ActionScript 3.0's new features, including the display list and new event architecture. The code can be used with the Flash IDE, Flex Builder 2, or the free Flex 2 SDK. Flash has long been one of the most approachable, user-friendly tools for creating web-based animation. This has contributed to making it one of the most ubiquitous forms of web animation, and there are some very powerful animation scripting capabilities at your disposalif you are still relying on key frames and tweens for the bulk of your Flash animation, you are missing out on some very exciting stuff! This book will teach you how to use Flash ActionScript to move the objects in your movie, rather than letting Flash's tween engine do it for you. The benefit of this is smaller, more realistic, more dynamic, interactive movies that almost literally seem to come alive on your screen. Although the text covers many advanced math and physics concepts, making for very realistic motion, there's no need to worry even if you are a relative newcomer to programming and the last math class you took was in high school (and even if you barely remember that!) The book starts with the all the basics you need to get started: principles of animation, and the basics of ActionScript, trigonometry and Flash rendering methods. It works its way slowly up from using code to move a single object across the screen, to the creation of complex systems that really push Flash's capabilities. Once you'll get to grips with it all, you'll find yourself creating all manner of exciting animations and games!

书中第十章的“线下”问题,并没有修正,小球从底部反弹至line的时候,仍然会穿过line到上面去,而不是反弹,将bounce参数调成-1就可以看得很明白了。 更改:如y2的绝对值小于小球半径,则进行反弹,如果y2的值为正则将小球重置到到线下,如为负则重置到线上 if(Math.abs(y2)...
评分 评分Foundation ActionScript 3 Animation这本书写得非常好。虽然从名字上看,是Foundation。其实,各种各样的效果大都是用最基本的行为叠加而成的。只有掌握了最基本的行为实现方式,才能够无穷地组合,创造出眩目的效果。 我写了很多年程序了,可是都这本书依然觉得非常受用。好...

评分书中介绍了动画中的物理方法,在不使用物理引擎的情况下,使用简单的物理定律进行模拟,对于一些简单的游戏已经足够了。
很基础,3D部分以后的简单浏览一下就可以
评分做游戏必备!数学和物理很重要!
