Knowing nothing about Actionscript and having pitifully little programming experience, I turned to this book as a first step in learning Actionscript. It is very much part of the "Type this, click that" teaching method, which is great for getting your feet wet. You read through and do the exercises and stuff happens on the screen. The author includes some detail about Actionscript, but he doesn't discuss anything in depth. I found myself wanting more information in just about every exercise.
For example, the book includes an exercise for making a sort of word game. The program has arrays of names, verbs, and nouns. The interface also has inputs for adding words to the arrays. When the player presses the "generate" button, the program is supposed to fill in the blanks with words from the lists. Unfortunately, I found that the program frequently fails to generate a word, leaving a hole in the sentence. I know that can be fixed; but if I want to fix it, I have to do research and fix it myself. The book goes no further.
Along the same line, most of the exercises are empty exercises. The author frequently ends sections with instructions to close the exercise windows without saving the work. Larger projects are not followed from start to finish, either. Everything is broken into bite-sized pieces and pre-digested.
I've never used Lynda products before. While I did get something out of the book, I wouldn't really recommend it because it's not rigorous enough to truly learn Actionscript programming. It's just an introduction. I suppose that's the idea. To get the full education, you have to buy more products and do more exercises. I will look elsewhere for more information and give this book three stars.
