How to remove a movieclip created with createEmptyMovieClip() ?


richardlmk said on Jan 30, 2004 at 6:49 AM :

Example...

_root.createEmptyMovieClip("myClip_mc",1000);
_root.myClip_mc.lineStyle(2,0xCCCCCC,100); // Just to show...
_root.myClip_mc.lineTo(50,50); // ... the MC was created
_root.myClip_mc.removeMovieClip();

Nothing should appear on stage as MC is "immediately" removed.

If you have problems with movieClips at <strong>extreme</strong> depths, try using unloadMovie();

I have a problem with unloadmovie - I have a set of say 200 clips I wish to remove e.g. -
for (i=1; i<( clip_num+1 ); i++){
_root.instance3.thumbnail_mc[i].unloadMovie();
}
... and then want to recreate maybe 20 clips (with different content) the originals are still there.
I think this may be a timing problem - are there any event handlers I could use to detect when each clip has unloaded?

How do I create a dotted line?

I am utterly stuck in removing empty movieclips...
What is the correct code for removing or unloading several empty MC
Is there 1 line that will do it all or do i have to unload each empty clip?


saester said on Jun 12, 2004 at 1:33 AM :

to remove empty clips created by duplicateMovieclip you should have used a naming convention as follows - "dupedClip"+i+"_mc" for each element in your loop - as such you can create a new function clearClips() that will simply run through the loop and call removeMovieClip() on each name - ie - you can do the following

for(i=0;i<numberOfClips-1;i++){
ptrClip = this["dupedClip"+i+"_mc"];
ptrClip.removeMovieClip();
}

this will remove all clips - ! ;)

Be careful not to try to set the _width or _height of an empty movie clip. Anything you try to put into that movie clip later will have visibility problems.

I can't seem to locate it, but removing a movie clip needs to be executed from the timeline that originally created the clip.

unloadMovie simply removes the contents of a clip, but the instance and the properties remain. To remove completely, use removeMovieClip()

Taking the example above:
_root.createEmptyMovieClip("myClip_mc",1000);
_root.myClip_mc.lineStyle(2,0xCCCCCC,100); // Just to show...
_root.myClip_mc.lineTo(50,50); // ... the MC was created

This works, but when I add:
_root.myClip_mc._width = 100;

it no longer shows. Is this a bug or am I doing something wrong?

Using trace to show the width before and after the extra line, shows zero both times.

The returned reference of the newly created MovieClip instance should
be supported for Flash Player 6 and later.

Hi Graham,

What you have encountered is a timing issue. You have to make sure the clip you are loading is fully loaded before initializing or making any other changes to it. I assume you're also loading a movieclip (if you just copy and paste your code below, it works for me because there's nothing being loaded). I can reproduce your issue just by adding the line:

logo_mc._width

to the example in the Example section of MovieClip.createEmptyMovieClip.

To ensure it is fully loaded, you should use the MovieClipLoader class. In the code below, I use the onLoadInit event to wait for the right moment to assign a new width to the movie clip:

this.createEmptyMovieClip("logo_mc", this.getNextHighestDepth());
// create listener object to receive a message when the clip is completely loaded
var myListener:Object = new Object();
// onLoadInit is designed for initialization of the loaded movie clip
myListener.onLoadInit = function(targetMC:MovieClip) {
logo_mc._width = 200;
}
// We need to use the MovieClipLoader class
var imageLoader:MovieClipLoader = new MovieClipLoader();
// Add our listener object to the imageLoader's broadcast list
imageLoader.addListener(myListener);
// Note that we use MovieClipLoader.loadClip instead of loadMovie.
imageLoader.loadClip("http://www.macromedia.com/images/shared/product_boxes/80x92/studio_flashpro.jpg", logo_mc);

greg_brant said on Mar 22, 2005 at 5:41 AM :

I have this code which seems to follow Francis Chengs ideas about timing which i totally agree with, however.

the _width of the target_mc returns 0

so
(target_mc._parent._width/2);

returns the constant Infinity

i would have though that, onLoadInit, the movieClip would have inherited the dimensions of the jpeg that had been loaded??

imageLoader.prototype = new MovieClip();
Object.registerClass("imageHolder", imageLoader);
imageLoader.prototype.init = function() {
this.img = this.createEmptyMovieClip("theImg", this.getNextHighestDepth());
this.listener = new Object();
this.listener.onLoadComplete = this.executeOnLoad;
this.loader = new MovieClipLoader();
this.loader.addListener(this.listener);
this.loader.loadClip("myImage.jpg", this.theImg);
};
imageLoader.prototype.executeOnLoad = function(target_mc) {
target_mc._parent._x -= (target_mc._parent._width/2);
target_mc._parent._y -= (target_mc._parent._height/2);
};

Hi I have created an emptymovieclip within a combo box on timeline 4 but when I try to refer to it in timeline 3 I can't seem to find it - can anyone help.
