Although I have a little experience with c++ I am an artist not a programmer. I have worked through this book for the last month or so, as a total beginner would and it is one of the best programming type books I have read. It is well written and even funny in places, which is always good. It leads you through setting up a project and all the basics about programming you need to know. Be aware this is a book about Actionscript3 so there is only a little about the drawing tools so learn a bit about them before you start. All coding is done within flash but as an external actionscript file with no timeline code, which is good.
There is downloadable code for each section but also a lot of code within the book. This may not be to everyones liking but for a beginner it is very handy. To start take the time to type in the code and follow along, it will be quicker to learn that way. OOP is left until half way through the book so you don't have to worry too much about the code being too complicated to start.
When the book goes to OOP it takes on a faster pace although everything is explained well and each section of code is described fully. A little more on oop structure would have been better but you will be able to figure out what it is doing and build upon the concepts you learn. Using arrays within your games is left to the end of the book which is a bit of a shame, but this is aimed at the beginner.
AI and physics is covered well with no maths talk.
In all I would say it is well worth the money and time if you want to learn Actionscript3 for games. Designers will especially like the pictoral descriptions of variables and all those other complicated concepts. Shame the oop stuff changed pace too quickly, it would have been better to add another chapter and ease you in more.
