If you follow my updates via Twitter, you probably already know about my decision to finally seriously start with ActionScript 3.0, something I have tried to avoid for a very loong time. In the end I couldn't ignore it any more and I realized that transition doesn't have to be rough with right tools.
First of all I have convinced myself that AS3.0 is completely new language, it's version number doesn't have anything to do with previous versions (besides creators) and I should start from scratch. Fact that I'm not so good at AS2.0 nether can only help :)
I'm starting with two books, first one I already wrote about is Learning ActionScript 3.0 : A Beginner's Guide, check my review.
Second book is The ActionScript 3.0 Migration Guide: Making the Move from ActionScript 2.0 and I'm not sure if latter one will help me or bother me on my way.
Since I have some experience with Java I found AS3.0 much more like it and some new language features are just like those in Java. Actually, I think AS3.0 is closer to Java than to AS2.0! (and I don't mean classes but OOP features). I read about Event Propagation, bubbling and Events in general and it's very easy to understand - for now. I must say I'm more excited about learning AS3.0 than I was when started with AS2.0. Wish me luck.
