Question

Consider this simple AS3 class.

package
{
     import flash.display.Sprite;
     import flash.display.MovieClip;

     public class MySprite extends Sprite
     {
         private var someMC:MovieClip = new MovieClip();

         public function MySprite()
         {
              super();

              addChild(someMC);
         }
     }
}

And this one:

package
{
     import flash.display.Sprite;
     import flash.display.MovieClip;

     public class MySprite extends Sprite
     {
         private var someMC:MovieClip;

         public function MySprite()
         {
              super();

              someMC = new MovieClip();
              addChild(someMC);
         }
     }
}

Is this the same thing, or is there more to it?

I guess its because in the first example, the MovieClip seems to exist before the contructor is called (when does this occur, what is the benefit or not?).

Answer 1

It’s all the same. The compiler translates your first example into the second. The only difference is that you can control instantiation order when you put the assignment into the constructor.
