ActionScript 2 - ActionScript 3: common subset?

Question

I'd like to automatically generate ActionScript classes for a flash client side of one of my projects. (These projects have a formal way of describing my models that is already used to generate SQL and a admin interface).

Now, the ActionScript should/could be compatible with ActionScript 2 and 3. Is there a description of a maximal common subset of features available somewhere?

Answer 1

I think you will be stumped right of the bat, because AS2 and AS3 declare there classes/packages differently.

If you are looking to create Classes from templates, then I would suggest using FlashDevelop. It has a get templating system.

ActionScript 2 Class/Package example:

class com.yourpackage.YourClass extends MovieClip {
  function YourClass() {
    //contructor
  }
}

ActionScript 3 Class/Package example:

package com.yourpackage {
  public class YourClass extends MovieClip {
    public function YourClass():void {
      //contructor
    }
  }
}

But this is all just syntax. There are a lot more fundamental deferences between the languages than just formatting. There is also a different way of thinking.

Answer 2

One possible alternative to enable you to do this, would be to use haXe.
