Flash Player API for ActionScript

Logo Adobe Flash PlayerImage by Dekuwa via Flickr

The Flash Player APIs in ActionScript 3.0 contain many classes to control objects at a low level. Adobe® AIR™ applications can also use the Flash Player APIs.
  • DOM3 event model - Document Object Model Level 3 event model (DOM3) provides a standard way of generating and handling event messages so that ActionScript objects can interact and communicate, maintaining their state and responding to change.
  • ActionScript 3.0 event model is based on World Wide Web Consortium DOM Level 3 Events Specification and provides a clearer and efficient mechanism. Events and error events are located in the flash.events package. The Flex application framework uses the same event model as the Flash Player API, so the event system is unified across the Flash platform.
  • Display list API - The API for accessing the Flash Player and Adobe AIR display list (the tree that contains any visual elements in the application) consists of classes for working with visual primitives. Depth management is now automatic and built into Flash Player and Adobe AIR. New methods are provided for specifying and managing the z-order of objects.
  • Handling dynamic data and content - ActionScript 3.0 contains mechanisms for loading and handling assets and data in your application that are intuitive and consistent across the API. A separate mechanism is also provided for loading text and binary data in data-driven applications. Reading and writing of binary data to server sockets in any format is also possible.
  • Low-level data access - Various APIs are provided for the low-level data access. Access to data as raw binary data while it is being downloaded. Optimal reading, writing, and manipulation of binary data. Detailed control of sound data.New APIs providing information about the security privileges of a SWF file or loaded content, for better security errors handling.
  • Working with text - ActionScript 3.0 contains a flash.text package for all text-related APIs and management of embedded fonts in SWF files.

Image via Wikipedia What is Flash ? Adobe Flash CS4 is a powerful multimedia creation tool used to create and display animation, video, and sound content. It can be also used to create Interactive Rich Internet Application (RIA). Flash can work with: Bitmap Graphics, Sound - you can change the compression of a sound by opening the Sound Properties window Video What are different Flash File types? Following are the different Flash file types: 1) Flash File (.FLA) - Flash working file (while creating artwork) 2) Flash Movie(.SWF) - contains Flash content which can be played in the Flash Player. 3) Video (.FLV, .F4V, .MP4) - These are video file type supported by Flash Player. Existing Movies can be converted to these format using Adobe Media Encoder which is included in Adobe Flash CS4. When you import a video into Flash the controls to play back the video is automatically added. 4) ActionScript File (.AS) - file containing Actionscript code. Using ActionScript you c...

Prototype based programming

Image
Prototype-based programming is a style of object oriented programming. Prototype based porgramming encourages the programmer to focus on the behavior of some set of examples and only later worry about classifying these objects that are later used in a fashipn similar to classes. Prototype based programming is also known as class-less, prototype-oriented or instance-based programming. Classless programming style is supported by the following programming languages. JavaScript, ActionScript , Lua Open Laszlo In prototype based programming behaviour resues ( known as inheritance in class-based languages) is performed via a process of cloning existing objects that serve as prototypes. Cloning refers to a process whereby a new object is constucted by copyin the behavior of an existing object (its prototype). The new object then carries all the qualities of the original. From this point on, the new object can be modified. The resulting child object maintains an explicit link...
