Excerpt: Filename extension : .as ActionScript is a scripting language based on ECMAScript . ActionScript is used primarily for the development of websites and software using the Adobe Flash Player platform (in the form of SWF files embedded into Web pages ), but is also used in some database applications (such as Alpha Five ), and in basic robotics, as with the Make Controller Kit . Originally developed by Macromedia , the language is now owned by Adobe (which acquired Macromedia in 2005). ActionScript was initially designed for controlling simple 2D vector animations made in Adobe Flash (formerly Macromedia Flash). Later versions added functionality allowing for the creation of Web-based games and rich Internet applications with streaming media (such as video and audio). Initially focused on animation, early versions of Flash content offered few interactivity features and thus had very limited scripting capability. More recent versions include ActionScript, an implementation of the ECMAScript standard which therefore has the same syntax as JavaScript, but in a different programming framework with a different associated set of class libraries. ActionScript is used to create almost all of the interactivity (buttons, text entry fields, drop down menus) seen in many Flash applications. Flash MX 2004 introduced ActionScript 2.0, a scripting programming language more suited to the development of Flash applications. It is often possible to save time by scripting something rather than animating it, which usually also enables a higher l...
