How to assign a custom class to multiple kinds of movieclips

[dcnguyen]

So on my stage and library, I have a movieclip for each state...named as STATE_AK, STATE_IA, STATE_NY, and so forth, inside the library...the clips are then placed on the stage

I've created a class called State.as, and have linked each of the state movieclips to this class.


How should I write the State class definition? So far, what I have is:

package{

import flash.display.MovieClip;

    
	public class State extends MovieClip{
		...
                public function State(){
                   ...
                }

                public function grow(){
                   this.scaleX = this.scaleY = 2.0;
                }                

	}
}

I'm not sure how to write the class so that it takes the existing movieclip as *the* movieclip, if that makes sense...so that the function "grow" doubles the size of the state.

I get an error like this:

TypeError: Error #1010: A term is undefined and has no properties.
