Me and my friend got this Actionscript book for a summer read. What can I say? It is perfect! Though it is not a actionscript "bible" but it goes in depth about actionscripting and debugging. It teaches you to work with actionscript like C++ or PHP. Unlike most books gives you pretty pictures and not much of explanations on what's going on. If you are a programmer or designer who just want to know what's behind the Flash magic, check out this book! It is all you need, and you won't have to buy another one. What's even better is that once you learn the language of Actionscript you won't have to worry about actionscripting in the MX family, there aren't much differences! It is like once you learn how to ride the bike, you won't forget it.
