What a disappointment this book is. It's far from being a bible because the layout of the book is seemingly completely random. It also is completely wrong about how realistic animation is achieved - I used to be a games programmer.
As a long-time C++ programmer, I needed both a reference and a learning guide. What this book, and its companion, equally useless Actionscript Bible, does is to go through all aspects of Macromedia Flash 8 in detail, by going through every little item available on the interface. We're literally half way through the book before we get to a section called "Building your first project"! This is exactly the wrong approach, the last thing you need to do is to learn every detail about something before you've started the hands-on part of learning. And in terms of being a "bible", which I take to mean a reference guide, what is needed is a strongly indexed set of sections about movie clips, the timeline, actionscript, the interfaces, web pages etc, and not just a random twaddle.
The way animation of a moving man is described is that of drawing the frames as though moving on the spot, and then applying just the right amount of movement on certain frames. This is wrong. The correct way of perfect movement is to draw a set of frames where the man moves through space within the area being drawn without any adjustment to the X or Y. Then, on the very last frame, where the next frame would be identical to the first, you add the pixel difference to the X and Y, before reverting back to the first frame once again. That's how it's done properly, and it is frankly astonishing that this so-called bible tells the reader the wrong way.
For me that's £40 badly spent.
