Essential ActionScript 3.0 [ペーパーバック]

This review is more of a 'heads-up' for any beginners considering this book. There are many reviews here telling about the book's contents, so I am going to talk about the level of the book instead.

I think it is important to state that this book is in NO WAY aimed or intended for beginners. None of the books in this series are, for that matter. Being fair, and I think this information is important for people even though a bit off topic: O'Reilly RARELY makes beginner level books. What they do make is insanely useful technical books which will tell you more than you probably ever wanted to know about a subject. But they are done, IMHO, very well. Still, when looking at books to buy I think it is important to keep this in mind, particularly if you are a beginner in any topic. Especially because most programming books are rather spendy.

When I bought Moock's first book, I had been using AS for a couple years (starting from Flash 4) and was still a beginner. However, I could manage my way through the very limited scripting options. When Flash 5 opened up the AS language to a full-blown environment, I was excited to get his book. Once it arrived, I was completely overwhelmed and immediately put it away. For about a year. During that time, I found other materials and boned up on my AS, THEN revisited the book. I found it much more useful.

When AS 2 came out, I thought the same thing. Ah-ha! I already know AS, so his book will get me up to speed. Wrong. The stuff which was pretty much lifted from the previous AS 1 book made sense, but I could not grasp what he was saying about the updates and new features in AS 2. Again, I put the book away for a year, found other resources to familiarize myself with, and revisited the book. I was surprised at the wealth of information I learned, but I learned it AFTER reading numerous other sources.

Leading to this book, I completely expect the same. I am buying it because I KNOW it will be a tome well worth the price based on my looking through it at local book sellers. No one, at least that I have read, has the depth of understanding of AS Moock does. He, IMHO, really understands the what and how. And he will tell you EVERYTHING about it. He does not, sadly, possess the 'layman language' to make this a beginner book. It barely makes sense to those well immersed in the topic. BUT, once you get to the level that you can absorb what he is saying, you catapult your Flash skills and usage.

For beginners, definitely start elsewhere. Books by Phillip Kerman or Joey Lott are marvelous entry level books. Both authors have a superior knowledge of Flash AS, but the also possess the ability to talk about it conversationally. A huge help in anyone's learning of a new subject. Flash AS is a huge uphill battle, but one which rewards richly for those who travel the path. I would just hate to have someone not try because they do not understand a book reportedly aimed at developers with 'no prior programming knowledge.'

First off, I agree with previous reviews that said its overwhelming for a LOT of people. That first chapter is a doozy.

Where I also have a problem with this book is how it instructs. I've been able to follow along with the coding but the author's explanation and instruction are lacking. Its obvious that he is very knowledgeable but he doesn't do a good job of passing that knowledge on. He's all over the place, explaining some things in depth, but not touching on other things you'll have questions about. At times it will feel like he is totally scatter-brained or ADD because he'll be going on about something inconsequential, while ignoring something else that you really want the answer to. Despite it being 900+ pages, I've had to go online to find answers to fill holes in his teaching. But also it feels at times like he's trying to talk over your head and give you the official-to-the-letter-Help-menu definition. I know there's a better way to teach people this stuff, and I've read books that do that.

I give it 3 stars just for the shear quantity, and I appreciate the effort. I just wish this book was not only packed with information but also taught it well.

This is not just an upgrade to Moock's earlier book on ActionScript 2.0. If you have that book, getting this one will not be a waste of time as this book is a complete rewrite. This book covers ActionScript programming fundamentals in exhaustive detail with clarity and precision. It explores ActionScript from a programmer's perspective, but assumes no prior programming knowledge. If you have never programmed before, start with Chapter 1. It will guide you through the very basics of ActionScript, and explain terms like variable, method, class, and object. Then continue through the book sequentially. Each chapter builds on the previous chapter's concepts, introducing new topics in a single, prolonged narrative that will gradually build your ActionScript skills and understanding.

If you are a designer who simply wants to learn how to control animations in the Flash authoring tool, you probably don't need this book, and Adobe's documentation should be sufficient. Come back to this book when you want to learn how to add logic and programmatic behavior to your content. If you already have existing ActionScript experience, this book will help you fill in gaps in your knowledge, rethink important concepts in formal terms, and understand difficult subjects through plain language. This book is divided into three parts.

Part I, ActionScript From the Ground Up, provides exhaustive coverage of the core ActionScript language, covering object-oriented programming, classes, objects, variables, methods, functions, inheritance, datatypes, arrays, events, exceptions, scope, namespaces, and XML. Part I closes with a look at Flash Player's security architecture. This section consists of chapters 1 through 19.

Part II, Display and Interactivity, explores techniques for displaying content on screen and responding to input events. Topics covered include the Flash runtime display API, hierarchical event handling, mouse and keyboard interactivity, animation, vector graphics, bitmap graphics, text, and content loading operations. This section consists of chapters 20 through 28.

Part III, Applied ActionScript Topics, focuses on ActionScript code-production issues. Topics covered include combining ActionScript with assets created manually in the Flash authoring tool, using the Flex framework in Flex Builder 2, and creating a custom code library. This section consists of chapters 29 through 31.

This book closes with a walkthrough of a fully functional example program--a virtual zoo, the pieces of which have been discussed as examples in explanations of various aspects o ActionScript throughout the book up to this point. Noteworthy ActionScript-related topics that are not covered extensively in this book include MXML, the Flex framework, Flex Data Services, the Flash authoring tool's built-in components, Flash Media Server, Flash Remoting, and ActionScript's regular expression support.

The great thing about this book is that besides covering the details of building a large scale application, it doesn't ignor small things like "With what do I compile an ActionScript program?", "What tools do I need?", "After I compile an ActionScript program, what exactly do I have?" Plenty of example code is shown throughout and the explanations are clearly written, so you shouldn't get lost if you read the book through sequentially. Highly recommended.
