By Ben Smith (auth.)

Advanced ActionScript 3 is a clean glance and new method of using useful, structural concepts and techniques which are usual within the box of wealthy interactive program improvement. With every one strategy damaged down into diverse strategized factors, you will find the procedure best suited for you. if it is an instance you could make the most of as-is, or one you can begin with and enhance additional, you have a word list of definitions and organizational strategies at your fingertips.

Object-oriented programming (OOP) and layout styles usually are not new to the sector, yet can usually be neglected of their price. they're, from time to time, not just overwhelming to profit, yet tough to place into perform. besides the fact that, they're helpful simply because they bring about a constitution that may be damaged down, rebuilt, and reused.

This version has been totally up-to-date to mirror sleek coding criteria and practices.

  • Provides the development blocks required for the implementation of OOP
  • Addresses difficulties and issues concerning OOP
  • Offers recommendations on how one can technique and make the most of OOP

Example text

By extending the MovieClip class to allow TestClip to be defined, the hashtable is removed unless you specify dynamic behavior for TestClip as well. This allows the nested clip to be accepted after your classes are compiled. If you were to define your clip as dynamic, you could get away with defining inner_mc as private. Again you’ve broken the concept of encapsulation, because you’re allowing dynamic behavior on the class. This is exactly what would occur if you declared TestClip as a sealed class and used it as the base class of ContainerClip.

These steps move toward accomplishing a specific goal. Each scenario has a clear beginning and ending, and there is always only one goal per use case. In short, a use case is a story that explains the system. Depending on the agency for which you work, getting your hands on the statement of work (SOW) is the optimal way to determine your use case. A SOW is a document that details the project requirements and defines the agency’s work activities. If you don’t have access to a SOW, ask the designer to detail the steps their comp demonstrates, as they understand them, and then walk through the comp with them.

This often reduces code reuse because you must write more to satisfy such needs. If code reuse appears to outweigh the optimization of typing, ActionScript offers a solution. 39 Chapter 2 ■ ActionScript 3: The Facts Behind the Basics Although I’m not advocating the use of weakly typed data or the lack of typing, the compiler isn’t as flexible the interpreter, known as AVM2. Because ActionScript is a dynamic language, runtime reflection is possible, which can make your applications more flexible.
