This book provides extensive knowledge of how to create a game in FlashMX. The book assumes a beginner/intermediate knowledge of ActionScript so it may be a bit too much for the complete novice. The book will explicity give code concepts and different ways of doing things like how to simulate gravity.
If you've a knack for ActionScripting, this book will help you to further understand new concepts specific to gaming like collision detection, physics, a.i. and multi-user code-specific concepts. The best way to learn how to create your own game from scratch is to learn these specific concepts as 'building blocks'.
If you can't decide which book to get on Flash game design, i'd recommend this one providing you have prior knowledge of Visual Basic and/or JavaScript and already know most programming concepts.
It is NOT for the complete ActionScript beginner i.e. no previous programming knowledge or experience. This book is aimed at programmers with existing knowledge of ActionScript or any similar languages as mentioned above.
