序言 When deciding if the book in your hands will be a good resource for your library, it might help you to know why we, the authors, wrote this particular book. We are both developers who use Flash extensively in our everyday work, but we are also teachers. Collectively, we have taught thousands of stu-dents at multiple universities, training facilities, and conferences, and yet weshare one significant common experience. We were consistently told that nofeature-rich ActionScript book satisfied this beginner audience.At first we were surprised at how truly overwhelming this sentiment was,but then we realized that we didn't have enough information to form anopinion. We didn't use beginner resources in our work and had only ourown curriculum to go on. So, we started to research how we could fill thisvoid and provide a book to our students that would really help them beyondthe classroom. We talked with a lot of students, user groups, and instructorsand began to sketch out a book that we thought would put what we learnedinto practice.When ActionScript 3.0 was released, the interested audience grew dra-matically Reactions ranged from excitement to uncertainty to fear, as theActionScript 3.0 learning curve became apparent. Talk of the Flash Platformsplintering into Flex （"developer"） and Flash （"designer"） camps left manydesigners and beginner programmers more uncertain than ever about theirfutures. When Flash CS3 Professional was released, the need for a guidingresource didn't dissipate （and, in many cases, increased）, and we knew it wastime to develop the book you hold in your hands.We hope this book will help Flash users of all kinds——from curious to intimi-dated, from eager to experienced——embrace the power and performance ofActionScript 3.0. We hope these pages will ease the transition from whateverprior version, if any, of ActionScript might have been in use, to the biggestarchitectural change to the language since its inception.
文摘 Much discussion has been made over the pros and cons of procedural ver-sus object-oriented programming. To touch briefly on this, here is a littlebackground concerning the evolution of ActionScript. ActionScript startedas a sequential programming language, meaning that scripting was limitedto a linear sequence of instructions telling Flash what to do in a step-by-stepmanner. This approach to scripting was not terribly flexible and did notpromote reuse.As the language evolved, it became a procedural programming language.Like sequential programming, procedural programming relied on a step-by-step set of instructions but introduced a more structured, modular approachto scripting. Procedures, otherwise known as functions （or, sometimes, sub-routines）, could be executed again and again as needed from different partsof a project, without copying and pasting copies of the code into the ongoingsequence of instructions. This modularity promoted reuse, and made thecode easier to edit and more efficient.Scripters in search of an even greater degree of modularity and reuse gravitat-ed toward object-oriented programming. OOP languages create programs thatare a collection of objects. Objects are individual instances of classes——collec-tion of code that are self-contained and do not materially alter or disrupteach other. Dividing code into small capsules, appropriately known as encap-sulation, is one of the hallmarks of an OOP language. Another important fea-ture of OOP is inheritance, or the ability to derive classes from parent classes,passing on specific characteristics from the parent.A classic example of OOP structure, and specifically inheritance, defines a setof transportation vehicles. You might start with a generic Vehicle class thatincludes traits common to all vehicles, such as the basic physics of movement.You might then create three subclasses: GrounclVehicle, WaterVehicle, andAirVebicle. These classes would alter or introduce traits specific to ground,water, and
