Actionscript 2 Proper way to define function on MovieClip -

i'm trying write function on movieclip, , call root clip. works fine in actionscript 3 doesn't seem working in actionscript 2.

frame 1 of _root movieclip:

var newmovieclip:movieclip = _root.attachmovie('notification', id, 0); newmovieclip.setnotificationtext("test text"); 

frame 1 of notification movieclip:

function setnotificationtext(inputtext : string){     notificationtext.text = inputtext; } 

the result movieclip created text not changed.

am doing wrong?

to add functions movieclip in as2, need use 1 of these methods:

1. add method prototype of movieclip:

   movieclip.prototype.setnotificationtext = function(inputtext:string):void {     if(this["notificationtext"] !== undefined)     {         // if we're going use prototype, @ least checks         // make sure caller movieclip has text field expect.         this.notificationtext.text = inputtext;     } }  newmovieclip.setnotificationtext("test text"); 

2. make movieclip , argument of function:

   function setnotificationtext(mc:movieclip, inputtext:string):void {     mc.notificationtext.text = inputtext; }  setnotificationtext(newmovieclip, "test text"); 

3. add method directly newly created movieclip:

   var newmovieclip:movieclip = _root.attachmovie('notification', id, 0);  newmovieclip.setnotificationtext(inputtext:string):void {     notificationtext.text = inputtext; }  newmovieclip.setnotificationtext("test text"); 

option 2 best overall - it's cleanest , avoids overhead of creating new function every new movieclip. avoids messing around prototype, @ best should used add generic methods, removeitem() method on array.
