If you are a beginner programmer or new to Flash, this book is a great resource. The book is focused on Flash rather than on both Flash and Flex. All examples in the first five chapters use Timeline scripting. AS3 classes are introduced and covered and the OOP nature of AS3 addressed but only after a gentle and very clearly written beginning. If you are planning to eventually venture into more complex AS3 applications, the authors recommend using their book in conjuction with The Essential ActionScript 3.0 or ActionScript 3.0 Cookbook. We would add ActionScript 3.0 Bible as another possibility.

A MUST!  As with all books by Colin Moock, this one is a must for ActionScript programmers. The author explains concepts with amazing clarity and depth. The book provides comprehensive coverage of AS3.

An excellent AS3 resource. Beware though, the book is meant for Flash as well as Flex and it does not address timeline scripting. On the other hand, the book contains answers to so many practical questions, we can't imagine working without it.

Unlike the previous incarnations of ActionScript Bible by J.Lott and R. Reinhardt, this ActionScript 3.0 Bible is not specific to Flash. It covers AS3 ehaustively on the level general enough to be applicable to Flash CS3, Flex 2 and 3, and the upcoming AIR - Adobe Integrated Runtime. AIR (now in public beta) provides desktop runtime environment for AS3 applications. Don't expect examples of timeline scripting and tips on Flash CS3 authoring! The examples in the book consist of collections of custom classes, one of which should be entered as a fla file Document Class. On the other hand, the coverage of AS3 begins with the basics and should be accessible to a beginner programmer.

This book is geared for game developers but it contains a lot of useful AS3 tricks that can be used in any context.

If you are interested in programmatic animation and not afraid of Object-Oriented programming, this book will teach you everything you need to know. The book by a renown AS expert, Keith Peters, is meant for Flash, Flex, and AIR developers. Together with lots of AS3 examples, it gives you a solid backgroud in mathematics and physics that you need to know to make your 2D and 3D animations realistic and cool.

The book covers AS3 from the beginning (statements, variables) but quickly moves to the OOP concepts. Most examples are in Flash but with the code placed entirely in outside files. The authors strongly advocate the OOP approach over Timeline scripting. If you like this approach, you will find the book very useful. If you don't but want to learn all there is to know about the Document Class in Flash CS3 (a new and interesting construct), this book explains it more throughly than any other.

The book is an excellent resource for learning Flash CS3 authoring environment, especially for handling media files. Most of code samples, though, are in ActionScript 2.

  For more advanced programmers.
