Learn more about the different versions of ActionScript, how to use them, and how to migrate projects from one version of ActionScript to another.


  • AVM1
    • ActionScript 1.0 The first and most diverse version of ActionScript. This started with simple timeline control commands and evolved into a rich, JavaScript-like language. Though old by today's standards, it is still used heavily with mobile devices.
    • ActionScript 2.0 An extension of ActionScript 1.0 that included a new class syntax for defining ActionScript classes in external (.as) files. When compiled, the resulting bytecode remains ActionScript 1.0.
  • AVM2
    • ActionScript 3.0 The drastically new, enhanced version of ActionScript that required a new virtual machine to be added to the player for it to operate. Much of the syntax is the same, but a lot has changed, including event handling, display object management, and XML (among others).

Latest Update: Yeah... pretty much dead here for now until I get back to work on things. Might take a while. I want to finish up some other projects first, one of which will be used here. Could take a while; stay tuned.
