ActionScript 3.0 :: Get MovieClip RemoveChild Or Not?
Sep 27, 2011
In stage button, MovieClip is there. When i click button remove the Movieclip. first time no errors. but next given below error. Ithink allready movieclip is removed from stage so how can i write code. And i also mentioned my codeTypeError: Error #1009: Cannot access a property or method of a null object reference.
at Untitled_fla::MainTimeline/onClick(
btn.addEventListener("click",onClick)
function onClick (e) {
This is something I'm experimenting with, but haven't seemed to figure out... I have several MovieClips, basically the same, only different colors. As each one plays, I'd like it to "overlap" whichever one is already there. Right now I have each button linked to a gotoAndPlay function, but I don't think that will ever get me what I want. You can see how I have it now here: [URL]
Instead of having the content MovieClip go back to all white when a button is clicked, I'd like the preivious one to remain, and get "covered up" by the new one. You continue to see the old color, and the new color overlaps it. I have a feeling I need to use a variable and then addChild, with a removeChild for the old MovieClip after the new MovieClip has loaded, but I'm not getting any good results yet.
I have a flash button that once clicked that adds an existing movie clip in my library to the stage. Basically what I am trying to achieve is like a popup window in flash so it opens a movieclip and then I have a close button inside the movieclip. Now what I want to achieve is to close the movieclip once I've added it to the stage.I'm trying to use the removechild but I'm getting errors e.g. The supplied DisplayObject must be a child of the caller.at flash.display::DisplayObjectContainer/removeChild()The way I add the movieclip to the stage is by using the following code:[code]
I'm trying to build a conditional statement that will addChild and removeChild at different Timer Delays. Before I go any further, I thought, I should mention that I'm usinig TweenMax to ease the alpha of ease Child from 1 to 0 and back during the process to imitate a fade-in/out.
I'm getting issue with only one line - inside a conditional statement.It's running "OK". The movie runs as I want it, but the remove/addChild transitions are not at the speed I want it at. I am getting an error message in the output, but other than that, the movie runs fine.
I am doing a project in which I need to open and close MovieClips. I have my Scene1 which loads the first MC (named "page1") then page1 plays and I would like it to unload itself and load the MC named "Page2" and so on up to page 10 ...
On the last frame of the MC "page1" I have this code: stop(); stage.addEventListener(MouseEvent.CLICK, animate2); function animate2 (event:MouseEvent):void { stage.removeChild(stage.getChildByName("clip1")); var clip2:MovieClip = new page2(); addChild (clip2); }
But all I get is this error message: TypeError: Error #2007: Parameter child must be non-null. at flash.display:isplayObjectContainer/removeChild()
I am trying to remove a movieclip from my main timeline but it is not working. you click a button that is in a movieclip that is dynamically added to the stage and it is supposed to remove a movieclip from the main stage. I added a trace to see if it was grabbing the right movieclip and it is. The error message that I am getting is:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
I have started learning AS3 after a long stint doing work on AS2, and to test my abilities, I decided to make a quick breakout game. It has gone fine so far until I get to the part where I need to remove the bricks when they are hit. My current code for the class of a Brick is attached, and is started when a Brick is minstantiated on the Stage. However, when I use:
parent.removeChild(this);
it makes the Brick invisible but the AS3 code still runs and the ball bounces off where the moveiclip of the Brick used to be; the eventListener for ENTER_FRAME I added still runs even though I have deleted the MovieClip. This doesn't work either:
this = null;
I have to say I don't like the whole Garbage Collection idea of AS3; it seems half-hearted and uncontrollable; being a .NET developer I am used to more control than this. What was wrong with "this.removeMovieClip();" and how can I correct this? My current swf: http:[url]....(there are other things wrong, like bad collision detection,
I have a simple catching game with objects falling from the top of the screen and when they are caught at the bottom I want a movieclip to appear with +5 to show the point scoring. I have set up a timer to show the mc then to delete it when it finishes. It all works apart from the mc will not disappear once the timer is finished. I have thrown a trace statement in to check that it is firing and that shows up fine. What the hell am I doing wrong? Here is the section of code:
completely remove the child of clip at 0 index? I read somewhere you should set to null to all the references to that clip, but I have no other reference in my code. The clip at 0 was added via a regular addChild().
I've created a MovieClip that opens other MovieClips. These MovieClips are galleries with example of my art and such. Within these gallery MovieClips there is a "close" button, which is actually another MovieClip.
the problem
Everything works except that when I open one gallery, then close it, then open it a second time, the "close" button refuses to work.
I thought this was do to my incorrect use of removeChild, but now I don't know.
This is made slightly tougher by the fact that closing the gallery involves playing a closing animation, so first I put the removeChild on the last frame of the gallery MovieClip. That had the same result so then I tried it this way.[code]...
I'm using an onEnterFrame handler to load an external swf file which works fine at frame 190..
var fl_Loader:Loader;addEventListener(Event.ENTER_FRAME, fl_EnterFrameHandler); function fl_EnterFrameHandler(event:Event):void{ fl_Loader = new Loader(); fl_Loader.load(new
I can't upload the file here because it is too big but I will post the code and a tutorial link plus the problem I've been having.
What the code does is, it gets an image and places it on your stage. This image you place there is reduced in size and when you click on it, it creates a magnifying glass effect.
It works like a charm and looks very cool but the problem is that when I want to go to another page of my presentation, the image stays there, this is because of the addChild function I'm guessing.
Once again, no problem, I just added this to the AS code of every page : removeChild.
You've probably already guessed it, this only works when the child has already been placed. If I go to my intro page and I place the code there it will give me an error since the intro comes before the gallery code. If I don't put the code there it only works if the gallery has already been loaded and I click on pages that come after the gallery.
So what I actually need is code that detects if the child has been loaded or not and if it has, it should be removed, if not, don't do anything.
U can find all the code underneath, it's quite a lot.

I'm trying to figure out why I can't remove the child of the meteors immediately after they have hit the planet or a building so that it would only damage the building once. When I try to just 'removeChild(meteorArray[k])' AS says that the 'object must be a child of the caller'. I'm not sure what that means, but I thought that the meteor was the child of the main document class.

I'm working on a pretty simple flash application which basically plays a music clip downloaded from a web URL, and makes a stick man dance. I have it all working fine, however, I've used the addChild function on the start button to add the mc onto the stage, however, when I applied the removeChild function to take it off again, I get an error telling me that it hasn't got a caller.Here's the script:[code]I've had my tutor look at it, and she can't work it out either, but I do get the feeling that she's not much wiser on Flash than I am.

I've set up and button/movie clip array so that when a user clicks on a button, that movie clip loads and the old one goes away. What I'd like to do is use "addChild" to load the new movie clip and "removeChild" to remove the previous clip. I've got the addChild thing...sort of...it loads all the movie clips onto the screen at once though and I can't get the script to work another way.
i have a quick question for you. Say i have a parent movieclip called "bob". Within "bob," i have another movieclip named "steve." within "steve," i have a bunch of other movieclips. Say i call removeChild(steve), from within bob. I know that will remove steve, but does that mean all the little movieclips within steve will be removed as well?
I'm loading content into my .fla from an external XML file using URLLoader. Once the XML has loaded, I'm looping through the XML to create an XMLList for certain elements. I'm then creating a text field to contain those nodes. Each node gets its own text field so that I can easily create text links. Here's my code (with non-pertinent lines removed)[code]...
I have a MovieClip that loads other MovieClips. These I refer to as Galleries as they display some of my different web and art work. Each of these galleries has a close button (actually a MovieClip...) which works well enough. However I find that if I close a gallery and then re-open the same one, the close button refuses to do it's job again. The gallery remains open.
I'm pretty sure this is because I haven't used removeChild correctly. I knew I had a problem with this before, but thought I had solved it. Since, when the galleries close button is clicked, it plays a closing animation I couldn't figure how to add the removeChild for the MovieClip. This is what it looks like (including my commented out failure...)
You have two arrays, both containing a different set of movieclips. You drag a movieclip form one array, in to one movieclip of the other array. You can do that as many times as you like. So in fact, the movieclips in the second array are all droptargets. The thing is, I have one erase button which should erase all the movieclips from the first array only when they are dropped on the droptargets from the second array. In other words.. how do I remove the content of the droptargets without removing all the droptargets as well?
when the start button pressed I would like to add the 'start_mc' and remove the 'score_mc' if it is on the stage and when the score button pressed I would like to add the score_mc and remove the 'star_mc' if it is on the stage. I don't really know how to go about this without any error.
So, I'm running through a bunch of children in a container, doing stuff to them, then removing them from the container. Since I have both the index and the object reference, would it be better to call removeChild or removeChildAt? I'm leaning toward removeChildAt, but I don't know what's happening behind the scenes, and it's possible that one is just calling the other. Here's the loop:
Code: for (var i:int = container.numChildren - 1; i >= 0; --i) { var kid:CustomClass = container.getChildAt(i) as CustomClass; if (kid != null)
