This book is perfect for those wanting to create exciting Flash content. Whether it be for games or just for learning to animate and create real-time objects in the Flash environment.
I don't usually refer to books but I found myself not even knowing where to start as far as emulating gravity and collision theories so I thought buying a book would be a good starting point. I wasn't disappointed and just reading a couple of chapters really opens up a whole new area of Flash.
However, you should be familiar with Flash's Actionscript language before buying this as the functions within Actionscript are never explained as they're being used within the book. Instead, some complex functions are just used assuming you're already fairly advanced at this.
This seems strange as making games IS a complex thing and, to the beginner, so is Actionscript so it seems only obvious to give a little more background on the actual Actionscript that you'll be using.
All in all, this is a great book, nicely illustrated on glossy paper which makes the learning somehow a little easier. Just brush up on your mathematics and Actionscript beforehand.
