everything and move on. The first of the last steps is to remove the
TimerEvent listener, so we can clear up a little memory. Next, we ll

dispatch a DataEvent and pass our REVERSE_COMPLETE variable from
earlier as the type.

'

TIP
For dispatching a simple event where you just need to listen for a custom
name but you don t need a full blown custom event class, consider

dispatching a DataEvent and using your custom event name as the type
parameter.

if (_currentLoop

_loopCount) {
_currentLoop++;
_targetClip.play();
}else{
_revTimer.removeEventListener(TimerEvent.TIMER,reverseFrame
);

_targetClip.dispatchEvent(new
DataEvent(REVERSE_COMPLETE,true));
_targetClip = null;

}

}

Sample Use of ReverseClip
For this sample, place a MovieClip in your library and give it
a Class/Linkage of

“ ball ” (or use the .fla available in the down-

loads from the topic s Web site). After creating a new instance

of ball named myBall , we jump straight into the action by
adding a REVERSE_COMPLETE listener to the ReverseClipSample
itself. Next, we

set up, let saddtheballtothedisplaylistusing addChild .Lastly,

reverseCompleteHandler simply traces out a notification that it
has indeed been called. Again, use the code that best suits your
project here.
