Can I reverse a tween created with the GUI ...with actionscript?

[paul_james123]

Hi All,

I'm newer to Flash so don't take much for granted. I have big gaps in my understanding.

I've created a motion tween (by right clickingon a movieClip on the timeline and choosing 'create motion tween'). Now I want to reverse it (using the 'yoyo' term) when the sound file is done playing. I know how to do this with a tween (using tween class) that was created with actionscript in the first place. How can I cause it to reverse if the tween isn't already (named and included) my actionscript?

Thanks

If you tween is in a MovieClip you can effectively play the MovieClip backwards like this:

addEventListener(Event.ENTER_FRAME, enterFrame);
function enterFrame(e:Event):void {
      prevFrame();
}

I do this all the time.

Thanks for your reply, Aaron.

How do I use that? (IOW: Where do I put that script?, How do I indicate the name of the movie clip it's controlling?)

So, for example: I'm starting the tween in my movie clip by making it visible (its an image that fades up because it's alpha state is tweened) : "myMovieClip.visible = true"

When that  image completely fades up, the image stays visible (100% of alpha state) for an indetermined amount of time then, I want a soundtrack cue to cause it to fade back down (tween back to 0% alpha).

This just happens once (not repeatedly).

Any help is appreciated.

Ok I realized that I put that in the frame script.

Thanks Aaron.

Now I just need to play that movie clip backwards when the sound file reaches a certain point. (I have already used a cuePoint in the sound file to make that movie clip to play forward).

IOW:

The script you sent:

addEventListener(Event.ENTER_FRAME, enterFrame);
function enterFrame(e:Event):void {
      prevFrame();
}


..is in the frame script of the movie clip and it causes the movie to reverse as soon as it played forward to the end. How do I get it to only go in reverse upon cue?

Thanks

What I would probably do is put that play-backwards in a function, something like this:

function playBackwards():void {
     addEventListener(Event.ENTER_FRAME, enterFrame);
}

Then you can give the MovieClip an instance name and call the playBackwards function from the parent:

myMovieClip.playBackwards();

Aaron,

You're probably assuming I know a lot more than I do. I'm getting this error: " TypeError: Error #1006: playBackwards is not a function. at reverseDissolve_fla::"

This is my action script in frame one of the main timeline:

// On Cue Point
function onCuePoint(event:CuePointEvent):void

{
    //This looks for only that cue point and takes action.
    if (event.name == "dissolveUp")
      {
         faceOne_MC.visible = true;
         faceOne_MC.play();// Makes the movie clip play (dissolves up using a tween).
      }

if (event.name == "dissolveDown")
     {
        //now I need to dissolve down when she says "wanted" by playing the faceOne_MC in reverse
        faceOne_MC.playBackwards();
     }
}

function playBackwards():void
{
     addEventListener(Event.ENTER_FRAME, enterFrame);
}

[paul_james123]

hold on. Ok I just realized that the

function playBackwards():void
{

addEventListener(Event.ENTER_FRAME, enterFrame);

}

function enterFrame(e:Event):void {
      prevFrame();
}

...goes in the frame script at the end of the dissolve in the movie clip.

Thanks much Aaron!
