AS3: Checking if movie clip chiled is added

hey,
I have few movie clips that are added and removed automaticly by users choice. The problam is I can't find a correct "if" condition that will check if the movie clip exists before I remove it. This is the part of the code:
function removeAnimation():void {
    if(Boolean(getChildByName('wheelChair'))){
        removeChild(wheelChair);
        chairTimer.stop();
I tryed getChildByName and everything I could find in google and came up empty.
Any help will be appriciated.

Just on the chance that it might apply, since you do use the wheelChair as an instance name in one line, try the following...
function removeAnimation():void {
    if(contains(wheelChair)){
        removeChild(wheelChair);
        chairTimer.stop();

  • RemoveChild for movie clip that was added in another function?

    Hello everyone.  I have 3 different functions for my preloader.  I have an Event.OPEN, ProgressEvent.PROGRESS, and an Event.COMPLETE.  In the event.OPEN function, I create a new variable that is data typed to the class name of my preloader that I set in it's property dialogue box.  This is just a simple circle animation.  Below is my code for it:
    function addPreloader(event:Event):void
        var myPreloader:mcPreloader = new mcPreloader();
        myPreloader.x = stage.stageWidth / 2;
        myPreloader.y = stage.stageHeight / 2;
        myPreloader.width = 75;
        myPreloader.height = 75;
        addChild(myPreloader);
    My ProgressEvent.PROGRESS function looks like so:
    function preloadImages(event:ProgressEvent):void
        var percent:Number = Math.round(event.bytesLoaded / event.bytesTotal * 100);
        percent_txt.text = percent + "%";
    and my Event.COMPLETE function looks like so:
    function imageLoaded(event:Event):void
        var myLoadedImage:Loader = Loader(event.target.loader);
        addChild(myLoadedImage);
        new Tween(myLoadedImage, "alpha", Strong.easeIn, 0, 1, 0.5, true);
        event.target.loader.removeEventListener(Event.OPEN, addPreloader);
        event.target.loader.removeEventListener(ProgressEvent.PROGRESS, preloadImages);
        event.target.loader.removeEventListener(Event.COMPLETE, imageLoaded);
    The only problem is that when it's done loading, I'd like to remove the myPreloader from the stage.  Since it is declared in the Event.OPEN function, I can't communicate with it via my Event.COMPLETE function.  How can I successfully remove it from the stage after it's done loading?  Thanks!

    Duh, thanks Kglad.  It's been a long week ;).

  • How to _root in as3 (buttons in movie clip referencing to main timeline)

    Hi, I created buttons within a movie clip that i placed in the main timeline.I am  a novice to as3. I just wanted the button to go to the frame label of the main timeline. i used to do this with _root in the old flash. how do i do this?
    thumb02_btn.addEventListener(MouseEvent.CLICK, buttonClicked);
    function buttonClicked(event:MouseEvent):void
        gotoAndPlay("slide2");

    Thanks for the quick reply!
    somehow i must be doing something wrong though. It's not working...
    I added a stop to the "slide02" labeled section of the main timeline.
    and I also added a stop to the beginning and end of the movieclip. Am I doing something wrong? attached is my file....thanks!!
    stop();
    thumb02_btn.addEventListener(MouseEvent.CLICK, buttonClicked);
    function buttonClicked(event:MouseEvent):void
        MovieClip(this.root).gotoAndPlay("slide2");
    stop();

  • Putting movie clips in AS3 package into movie clip on stage

    Hi - I am a as2/flash animator and am working on an AS3
    project. The AS is in a separate file, inside a package. I am
    modifying existing code.
    The script adds movie clips in a function via addchild.
    What I am hoping to do, is have the movieclips added to a
    clip that already exists on the stage.
    I put a clip on the stage named holder, with the instance
    name holder_mc - and I tried to add the clip with
    holder_mc.addchild in the AS3 file - it seemed to work, but
    manipulating the holder_mc - it looks like the added clips are not
    affected?
    Any help is appreciated.

    Child_array is a property of the Parent class.
    It's only added to in one point, in a function that creates a
    Child and adds it to the array.
    I think I might have found out the problem with my code after
    adding a trace to the function, think I'm creating twice the number
    of clips I'm removing, and the deletion part of my code is fine!
    Turns out AS3 is maybe not so bad after all :P
    Thanks alot for taking the time to reply though kglad!

  • AS3 to make movie clip not play on default?

    I created a movie clip that I want to play when a button is
    clicked and
    stop when another button is clicked.
    I have a stop action on the first frame where the 2 buttons
    appear and
    the movie clips resides. When I test the movie, the movie
    clip plays by
    default.
    How do I set it up so the movie clip does not play until the
    user clicks
    the play button?
    The code I am using:
    myPlay_btn.addEventListener(MouseEvent.CLICK, playMc);
    myStop_btn.addEventListener(MouseEvent.CLICK, stopMc);
    function playMc(e:MouseEvent):void{
    my_mc.play();
    function stopMc(e:MouseEvent):void{
    my_mc.stop();
    Thanks!!!

    Not sure if I understand. Where specifically should this be
    added to the
    code:
    myPlay_btn.addEventListener(MouseEvent.CLICK, playMc);
    myStop_btn.addEventListener(MouseEvent.CLICK, stopMc);
    function playMc(e:MouseEvent):void{
    my_mc.play();
    function stopMc(e:MouseEvent):void{
    my_mc.stop();
    Thanks!

  • Check for movie clips with AS?

    Is it possible to check if a frame contain a movie clip with

    "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)

    mx.transitions.TransitionManager.start

  • AS3 How reload Movie Clip.

    hi,
    1,How reload Movie Clip...?
    2,i think when we remove a Movie Clip,children and all instance object are also removed  from stage but it still use memory of server..right..?

    1.  how'd you load the movieclip to start.  (ie, copy and paste the relevant code, ONLY.)
    2.  readying displayobjects for gc (so they're no longer using memory) requires removing from the display list, removing all listeners and nulling all references.

  • Animating dynamic move clips.

    I have an unknown number of movie clips tat are added
    dynamically. I can add them fine but i want to add them so they
    appear off stage at a random x, y pos and then slide in and ease up
    to another random spot on the screen. So each time the movie is
    loaded it looks lik someone has thrown a bunch of photos out on a
    table and they slide and spread to random locations and ease to a
    stop. Anyone have any clues? i have found a number of tutorials but
    would like some extra help/explanations.
    Cheers.

    very basically, it should be something like -
    once a MC is loaded place it randomly offstage, and then
    using the Tween
    class move it to a random location on stage.
    for further information, read the help files about 'random'
    and 'tween'.
    good luck,

  • Detect if movie clip is visible inside browser window

    Hello.
    It's easy to check if movie clip is on the stage/display list.
    But how to detect if movie clip is inside the visible area of browser window?
    Any ideas?

    if you don't know anything about the movieclip and you are not consistant with your registration points check its colorRectBounds using the bitmapdata class.  otherwise, check its x,y

  • How do I create a play button for movie clip using AS3

    Hello.
    Bit new to this and have been searching the adobe forums and google. I am trying to create a button that will play an imported MovieClip.
    I have a movie clip that I've imported into it's own layer (Layer1) Frame 1.  I've given the MovieClip an instance name of foundationMovie.
    I've created a button and have that on its own layer(Layer2) above layer1, it is also in Frame 1.
    I've added a
    stop (); action to layer2
    The video is not set to autoplay.
    I want the video to start playing when the viewer clicks the button.  I know I've got to put some kind of event listener using AS3 in my timeline somewhere.
    I've found some code and I've been trying to work with it.  I'm sure I've mutilated it beyond usability but this is what I've got.
    stop ();
    player.addEventListener(MouseEvent.CLICK,play);
    function play(event:MouseEvent)
    gotoAndPlay("foundationMovie");
    If someone could point me the right direction or help me with my code I would really appreciate it.  Thanks.

    First, you need to clear up what you are working with... a movieclip and a video are usually entirely different things.
    Next, your code may get you started on your way with some changes.   You shouldn't use "play" as a function name due to there already being a play() method/function in Flash.
    If the movieclip is a movieclip and has an instance name of "foundationMovie", and your button has an instance name of "player" then the following adjusted code would normally work...
    stop ();
    player.addEventListener(MouseEvent.CLICK,playMovie);
    function playMovie(event:MouseEvent)
         foundationMovie.play();

  • How can I display a Movie clip from library on stage in AS3?

    Hi,
    I have a movie clip in my library and I would like to display it on the stage using AS3.
    do I have to define it as a variable?Do  I need to use this code:  addchild(movieclip);
    can I use the 'x' and 'y' to position it?
    What would the code look like?
    Ben.

    Great! it works  well ! thanks
    But I have another question, if I wanted to used the same movie clip but postion it at different x and y positions when a different btn is selected how could I do that?
    Would I have to make a copy of the movie clip and give it a different name?
    or is there an better way around it?
    Ben.

  • AS3 Putting Buttons Inside Movie Clip

    I am practicing AS3 (after years of AS2) and am having trouble having a button inside a movie clip talk to another movie clip on the main timeline. Here is the code:
    OneButton.addEventListener(MouseEvent.CLICK, OneButtonClicked);
    function OneButtonClicked(event:MouseEvent):void
    MovieTarget.gotoAndStop(1);
    MovieDescription.gotoAndStop("One");
    TwoButton.addEventListener(MouseEvent.CLICK, TwoButtonClicked);
    function TwoButtonClicked(event:MouseEvent):void
    MovieTarget.gotoAndStop(2);
    MovieDescription.gotoAndStop("Two");
    The code above works, but if I put OneButton and TwoButton inside a movie clip, I know longer can target MovieTarget and MovieDescription. The reason I want to put OneButton and TwoButton inside it's own MC is so I can dim each button after it is clicked by toggling the playhead inside that MC. Help? Thanks!

    Start over from the begining
    press  f8 and chose movieClip then draw your untoggled button call the movie button then create another movie and create your toggled button or greyed out button and call it greyedButton.  Go to main stage add 2 button instances and 2 greyedButton instances( just drag from library).  you have 4 instances on stage.  give call instance names and place one them on top of each other so u can only see 2 buttons on stage.  put the greyed button under the button.
    now with action script
    button1.addEventListener(MouseEvent.CLICK, OneButtonClicked);
    function OneButtonClicked(event:MouseEvent):void
    MovieTarget.gotoAndStop(1);
    MovieDescription.gotoAndStop("One");
    button1.visible = false; //  here the greyed button will show
    button2.addEventListener(MouseEvent.CLICK, TwoButtonClicked);
    function TwoButtonClicked(event:MouseEvent):void
    MovieTarget.gotoAndStop(2);
    MovieDescription.gotoAndStop("Two");
    button1.visible = true; // here button1 will go back to its orignal state
    button2.visible = false // here the greyed button will show

  • Center movie clips dynamically, as3.0

    Hi.  I have seen this discussed both on Adobe Forums and other sites but I can't seem to make sense of the code supplied by what I have seen thus far.
    I am trying to center display objects that are added to the stage at runtime dynamically through a basic drawing application.
    the code is something like this:
    1. add an event listener for the drawing event.
    2. add the path you want to draw to a container movie clip on the stage.
    3. add an enter-frame event listener to change the scale of the path randomly .... and this is the moment i want to change the default top,left registration point to the center,center of the path.  each path has its own registration point as i can tell thus far but at this point the scale is happening from the top,left of the container rather than about the path's own self.  and if it were to happen about the path i would have to get the bounds of the path and do some averaging to center the registration point.
    unfortunately i don't know what the code looks like to achieve what i'm trying to get.
    any help is appreciated.  thanks in advance.

    Well if using the graphics.lineTo method is Bitmap data then that is what I'm using.  But each call to the shape that I'm drawing is a new Shape(); .  The second paragraph you wrote seems a bit daunting when viewing it in the abstract sense.  Your first reply was a bit more concrete but I guess the first response didn't account for everything being in one container.  Should I create a container2 Movie Clip and create that as a new box on a per-shape basis so that I have multiple container2 mc's in the following path:
    container.container2[i].shape[i] where i would be an index (such that i++) though the code wouldn't be written exactly that way. ?
    (To store localX,Y positions in an array or vector shouldn't be too hard but I would need to try it several times before I get it right).
