Duplicate MovieClip in AS3.0

with 4 comments

Like duplicateMovieClip in AS2.0, here is an API to do the same in AS3.0, So just chill 🙂

* usage: var dupMC:MovieClip = duplicateDisplayObject( MC1 );
* @params -  target:DisplayObject - The movieclip to be duplicated.
*            autoAdd:Boolean - default is false, setting it to true will add the new
*            duplicate movieclip to the parent of the to be duplicated movieclip

public function duplicateDisplayObject( target:DisplayObject, autoAdd:Boolean = false ):DisplayObject
     // create duplicate
     var targetClass:Class = Object(target).constructor;
     var duplicate:Sprite = new targetClass();

     // duplicate properties
     duplicate.transform = target.transform;
     duplicate.filters = target.filters;
     duplicate.cacheAsBitmap = target.cacheAsBitmap;
     duplicate.opaqueBackground = target.opaqueBackground;
     if ( target.scale9Grid ) {
          var rect:Rectangle = target.scale9Grid;
          duplicate.scale9Grid = rect;

     // add to target parent's display list
     // if autoAdd was provided as true
     if ( autoAdd && target.parent ) {
          target.parent.addChild( duplicate );
     return duplicate;

  1. Hi there,
    It seems like for this method to work, the duplicated DisplayObject has to have a linkage id in the library- set Export for Actionscript in the library item’s properties.

    • Not really, I have tested this with Flex SDK 3+ and it worked fine.
      Not sure if this will work with flash. Just need to check the APIs used compatibilities.
