Hi every body

I've been looking around without great success to solve this little problem of mine and it goes like this;

By clicking two button on stage I create two MovieClips called EVE and BLOCK... That's because the buttons display objects with addChild.

function newMcEvent():void

{

          var eve:MovieClip = new event_graphic();

          eve.x = 50;

          eve.y = 350;

          eveNum++;

          eve.name = "eve " + eveNum;

          addChild(eve);

          eventArray.push(eve);

          for (var i:int = 0; i<eventArray.length; i++)

          {

                    eventArray[i].addEventListener(MouseEvent.MOUSE_UP, touch);

                    eventArray[i].addEventListener(MouseEvent.MOUSE_DOWN, drag);

                    eventArray[i].addEventListener(MouseEvent.MOUSE_UP, noDrag);

                    eventArray[i].addEventListener(MouseEvent.MOUSE_DOWN, snap);

          }

}

function newMcBlock():void

{

          var blc:MovieClip = new block();

          blc.x = 50;

          blc.y = 350;

          blcNum++;

          blc.name = "blc " + eveNum;

          addChild(blc);

          blockArray.push(blc);

          for (var i:int = 0; i<blockArray.length; i++)

          {

                    blockArray[i].addEventListener(MouseEvent.MOUSE_UP, touch);

                    blockArray[i].addEventListener(MouseEvent.MOUSE_DOWN, drag);

                    blockArray[i].addEventListener(MouseEvent.MOUSE_UP, noDrag);

          }

}

BLOCK has the same code as EVE and has also a small invisible area that I want to use for snapping objects (called SNAP, it's a nested movie clip!)...

What I want to do is to add to EVE an EventListener.MOUSE_DOWN that triggers a function called snap... this way I can check if EVE is actually HitTesting the movie clip BLOCK....

I manage to write down this code

function snap(e:MouseEvent):void

{

          if (e.currentTarget.hitTestObject(Object(root).blc))

                    {

                              trace("ok");

                    }

}

It returns Error #2007: Parameter hitTestObject must be non-null. which I take as the fact it can't find BLOCK or some reason, but it's there I swear!

Any idea?
