Removing movie clips with added children

If I have a movie clip added as a child to another movie clip
on the stage, and I remove it's parent, and null all references to
the parent, will both the parent and child movie clip be deleted by
the garbage collector? If so, will it be done on it's regular pass
or by mark and sweep?

OK, so if I add a movie clip like this:
function addMovie()
var toAdd:MovieClip = new Example(); // example extends
movieclip
this.addChild(toAdd);
I'm assuming that toAdd will be nulled when the function is
complete, because it's a local variable. Then if I put code inside
the movie clip at a certain frame or in a function in the class
Example to get rid of it:
this.parent.removeChild(this);
I'm assuming that's all i need to do to get rid of it. I
can't null the instance of the class Example using this = null from
inside it, and the only reference to it is the child reference from
the parent.
Am I right or is there more I need to do to make the instance
of example eligible for GC?

Trying to remove movie clip with collision?

I am creating empty movie clips and populating them with
movie clips that have "drag and drop" functionality. I can create
the empty movie clip and populate it with an external .swf. I've
even got the drag-n-drop handled. But, I'd like to have them delete
or disappear when they are dropped onto a trash can movie clip. I
just can't seem to figure out the code for this. I would greatly
appreciate any help you could give me.
Thanks.

you need to perform a hitTest to determine if the item is
within the bounds of your trashcan, you can also use _droptarget,
but I prefer hitTest with a shapeflag parameter. depending on your
code, when you call stopdrag onRelease, run your test there.
the_mc.onRelease = function() {
stopdrag();
if(_level0.trashcan.hitTest(_xmouse, _ymouse, true)) {
this.removeMovieClip();
}

Copying movie clip with flv

Hi, I am trying to copy a movie clip with an flv in it from
one project to another. Everything works fine except the flv just
keeps trying to load and never plays. I am not sure what to do. Any
suggestions?

It sounds like you are using the FLVPlayback component to
display the FLV, in which case, the FLV is a separate file and
likely needs to be in the folder next to the new project. Go back
to the old project and copy the FLV from its location there to the
new projects folder.

Noob help: Triggering Movie Clips with Buttons

Hi guys,
I'm taking an intro Flash and Action Script class and for my final I need to create a portfolio project that contains 5 unique buttons that trigger 5 unique movie clips. I'm having a hard time with this. I've been able to trigger the 1st movie clip with the first button (although I can't stop it) but I can't trigger any ohter movies with any other buttons.
Here's my code:
stop();
chuck1_btn.addEventListener(MouseEvent.CLICK, playMovie);
function playMovie(event:MouseEvent):void
    spaceship_mc.play();
chuck2_btn.addEventListener(MouseEvent.CLICK,playSaucers);
function playSaucers(event:MouseEvent):void
    saucers_mc.play();
Nothing happens when I click on chuck2_btn when I test the movie. I think I need to create a variable or class but I'm not sure. I'm a super noob with this stuff. Any thoughts? Thanks!
Rick

You should learn how to use the Help documentation to find answers like how to use the visible property. For the code you showed earlier, here's what you can try in frame 1 to replace it.
stop();
spaceship_mc.visible = false;
saucers_mc.visible = false;
slideshow_mc.visible = false;
chuck1_btn.addEventListener(MouseEvent.CLICK, playMovie);
function playMovie(event:MouseEvent):void
     spaceship_mc.visible = true;
     saucers_mc.visible = false;
     slideshow_mc.visible = false;
    spaceship_mc.play();
chuck2_btn.addEventListener(MouseEvent.CLICK,playSaucers);
function playSaucers(event:MouseEvent):void
     spaceship_mc.visible = false;
     saucers_mc.visible = true;
     slideshow_mc.visible = false;
    saucers_mc.play();
etc...
It could be refined, like having a function that hides everything and using that every time before making the one you need to show visible. You might find it necessary to include telling the movies to gotoAndStop(1) as well.
That's about as generous as I'm going to get. It's important that you learn things, and handing you a solution isn't going to help do that.

Check for movie clips with AS?

Is it possible to check if a frame contain a movie clip with
AS, and then if movie clip is found run a function? Like a global
"event handler " for movie clips.

I want a function that automaticly can detect and fade in any
movie clip found in any keyframe in the main timeline. So i don't
have to make
In the first keyframe in the main timeline
on (ohh here i found a movie clip)
//let's run a nice fade function on that movie clip
mx.transitions.TransitionManager.start
(eval(TheClip),
{type:mx.transitions.Fade,
direction:0,
duration:1,
easing:mx.transitions.easing.None.easeNone,
param1:empty,
param2:empty

Moving movie clips with ActionScript

I am trying to move four movie clips with actionscript in a
circler motion with two buttons, one to rotate the mc’s to
the left and one button to rotate the mc’s to the right. Here
is a link to what I am trying to do;
http://www.us.playstation.com/Lair/
and it is undrer game features.

Yes, that's what the code I gave you is intended to do....
you replace that code with whatever action you need to take to turn
your movie around.
I have no idea what your movieclip is doing, but I'm guessing
by your response that if it was an arrow pointing left to right
(just an example), you want it to be pointing right to left when
the left arrow is pressed. If you want an immediate turn around,
then the simplest way to do that is to have another frame
containing the movieclip that it moves to where it faces the other
direction--and to have it appear turned around, from the toolbar
you select Modify -> Transform -> Flip Horizontal.
So the movieclip would live inside another movieclip that has
two frames with stop()'s for each frame. In the first frame you
would have the subclip facing left to right, and in the second you
would have it facing right to left. If we call that 2-framed
movieclip "walker", the code I provided before would
become...

Exporting a move clip with alpha channel

Hi there,
I’m trying to export a move clips with alpha channel.
I’m trying to export an animation with Premiere CS5. I made an animation of a rotating object in Maya and exported it with alpha channel as tiff images. Then they are edited with Photoshop to give them a drop shadow.
My problem is this. Can I export this tiff animation with the alpha channel?
My plane is to use move clips over backgrounds in a game – depending on the result there are different animations playing on top of several different backgrounds. There for the objects has to have a transparent/alpha channel over the backgrounds.
Again the reason for this is the complexity of the game and to make the game looking as real as possible. I’m hoping for some help here to make my plan possible
…thanks

Thanks alot for the help.
But now I’m wondering how to get the file size down?
The 32bit and alpha channel just increase the file size from about 1MB to 9,3MB, which is pretty much??
…any ides mate?

Help! Remove Movie Clips

OK...here's my problem... I am making a portfolio site and I
have my thumbnails being created dynamically through XML...very
similar to the galleries example in the Sample and Tutorials. Only
problem is that I have multiple keyframes with different thumbnails

work but the thumbnails from the first frame are still showing on
the second frame...How do I remove the dynamically created movie
clips?

Removing movie clip in a frame

Hello,
I have a timeline with 12 frames, in frame 7 I added a movie clip to the stage:
var pContainer:MovieClip = new MovieClip;
addChild(pContainer);
var myLoader1:Loader = new Loader();
pContainer.addChild(myLoader1);
var myRequest1:URLRequest = new URLRequest("flash/products.swf");
myLoader1.load(myRequest1);
pContainer.x = stage.stageWidth/2 - 380;
pContainer.y = stage.stageHeight/2 - 180;
now, when I hit a button and I go back to frame 2 or any other frame in my movie, this movie clip is on top of everything,
I tried in frame 2:
removeChild(pContainer);
but it doesn't remove the movie clip any ideas?

Managing things you create dynamically can be tricky business... I don't yet know why.
One way of doing this is to manually plant pContainer as an empty movieclip symbol in frame 7 rather than creating it dynamically.
Another thing to try would be to use the removeChild command before you move away from frame 7. So you might need to have a conditional in your button that tests the currentFrame value and then executes the removeChild command before moving to the destination frame.

How to play a movie clip with a tween animation

I created a movie clip symbol with a tween animation and created an instance of it on the main stage. The animation is in the movie clip timeline, not on the main timeline. I cannot get the mc to play using mc.play() or mc.gotoAndPlay. What am I missing??

Hi Ned, thanks for the response;
1.Yes I named the instance.
2.I don't beleive so. I started from the library creating a new symbol, added the graphics, added the key frames, then created the tween. Then I dragged the symbol onto the main stage and named the instance. So I don't think there is a movie clip inside an mc.
Here is the main timline:
Here is the mc timeline:
Here is what I'm trying to do:
stop();
blk1._visible = false;
blk2._visible = false;
blk3._visible = false;
ppk1._visible = false;
ppk2._visible = false;
ppk3._visible = false;
storeCartons = new Array();
storeCartons = [blk1, blk2, blk3, ppk1, ppk2, ppk3];
startButton.onRelease = function() {
    myNumber = Math.floor(Math.random()*storeCartons.length);
    trace("myNumber "+myNumber);
    activeCarton = storeCartons[myNumber];
    activeCarton._visible = true;
          activeCarton.play();

Editing quick time movie clips with sound

We are editing together some quick time movie clips but we can't get the sound to come up.
Is there something we are doing wrong? Can you split the voice from the visual when you bring these clips into Final Cut?

A QuickTime movie can be made from any number of codecs. Which one are you working with?
If it's an MPEG video, chances are it will need to be demuxed. You can use MPEG Streamclip for this and other conversions.

Changing depths of movie clips with button clicks

Hello all,
I've got a file on working on that has 4 different movie clips on one layer that, when clicked, will zoom in (made with tweens in the timeline).
The issue I'm having, is that when I click one of them, they are arranged in a way that won't work for what I need. I click one, and it works, but it is hidden by the movie clip that is on top of it in the heirarchy. Click another, zooms in, but is partially hidden by another one.
My question is: Is there anyway in AS2 to code these so that when one is clicked, it will the top spot in the heriarchy? So that I can code them all like this so that whenever one is clicked, it goes to the top so it is not hidden?
Thanks

Correct me if I'm wrong, but isn't that just used to swap 2 movie clips?
Or is there a number I can input instead of the movie clip name that will change all of them?

Movie Clips with one Frame

If I have SWF's that I am using for UI elements in a game, and in these SWF's there are layers with Movie Clips and these clips have only one frame in them - do I need to explicitly put a stop() in there for optimal performance?
I'm curious if these movie clips sit there and loop with only one frame and in the end hurt the game's overal FPS
Any insight would be appreciated

please don't cross-post.
