ActionScript 3.0 :: How To Remove Child After Adding

Jul 24, 2009

I'm not talking about removing a child by simply using the removeChild(); method, but a more complicated (I think) way. For example, If a add a 'box' MovieClip with addChild, and I have a 'close' button inside the 'box' MovieClip, I want the 'box' MovieClip to disapear when I press the 'close' button. I tried

Code:
addEventListener(Event.ENTER_FRAME, onEnterFrame);
function onEnterFrame(event:Event):void {

ActionScript 3.0 :: A Class Adding Itself To Display List?

Dec 14, 2009

What i'm trying to do is create an errorAlert class. The role of this class is to as you might expect display an alert:) So the current class is set up in such a way.
 
1. pass in an errorcode returned from the server into the constructor.
 
2. This runs through a switch and sets a msg variable to the right textual prompt based on the code. At this stage it also sets an alert type, so as an example it could be a severe alert where the user has no option other than ot refresh the browser. Or it is a softer alert where the user is able to press a close button and proceed.
 
Because all of the type handling and everything is held within the class. I want to avoid adding the instance to the display list within the main document class. Ideally just letting the class add itself to the stage AND IF it is a softer alert, it can show the close button, add an event listener, and, then remove itself.

ActionScript 3.0 :: Adding Image More Than Once To Display List

Dec 26, 2009

I load an png image and add it to the display list. Now I want to add this image more than once, like a pinball game there could be 3,4,5 balls, all with the same image. But I cant add the same image reference more than once to the display list, right? So should I make a copy of it? How can I copy it and add to the display list without needing to load it from file more than once?

ActionScript 3.0 :: Cannot Remove Display Object Must Be Child Of The Caller?

ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.

at flash.display::DisplayObjectContainer/removeChild()
at working_loader_container3_fla::MainTimeline/frame4()

I have been getting this error after a bunch of different ways of trying this.  I am attempting to create a new instance of my movieclip which displays external images via xml. I want a new instance of the movieclip every other frame and need to be able to remove each instance on every other frame.  It will work going forwards, with a remove child call but as soon as I go back a frame, the error pops up.

ActionScript 3.0 :: Adding Single Image To Display List?

Mar 31, 2010

I have a single image I imported to the library of an Fla document. I could have easily imported it to the stage, but I chose the library instead. It is a .png file. It's name is ace_clubs.png. On import a symbol was created  by Flash and I deleted it. THE ONLY THING IN THE LIBRARY IS ace_clubs.png . I then right clicked on the the image and filled in for properties the following:

1. Export for ActionScript

2. Export in Frame 1

3. The class was by default named ace_clubs.png which I renamed to
my_images .

4. The base class by auto default is flash.display.BitmapData

So how do you get the image (ace_clubs.png) to display in the Flash movie at say
(0,0) ? Meaning in the ActionScript window what code is needed?

Flex :: Resize A SpriteAsset Without Adding It To The Display List?

Mar 31, 2010

I have an embedded image asset (with a scale9 grid), and I'm trying to get the bitmapdata when it's resized, but I can't seem to do this without adding it to the display list.

I try this:

spriteAsset.setActualSize(w,h);
spriteAsset.width = w;
bmd.draw(spriteAsset);

But when I then draw out the bitmapdata with graphics.beginBitmapFill(), I just get the original un-stretched image.

Or do I need to take 9 separate BitmapData images and make 9 separate bitmap fills?

ActionScript 3.0 :: Adding And Removing Movieclip From The Display List?

May 9, 2011

why I cant kill a child in my display list. So I'm working on an ad that is going to load in different swfs depending on the link you click. What I wanted to happen is when the ad loads the first swf is auto loaded in to my container. Then when you click on the next link the new swf would cancel out the last one. What I am getting is an overlap of the swfs and I understand that. I can't figure out how to kill the other children. I tried unload and remove child but have been unsuccessful.

Actionscript 3 :: Event For Monitoring Add/remove MovieClips From Display List?

Jul 13, 2011

I have a movieclip, let's call it "myMC", that is very long (5,000 frames) over the course of which many dozens of nested movieclips are added/removed as children to/from "myMC".Without reference to the nested clips, is there a way I can add a listener to myMC and listen for when an object is added/removed from it (something along the lines of Event.ADDED)?

ActionScript 3.0 :: Adding Buttons Via Display List Breaks This Function?

Jan 31, 2012

I'm trying to add the btns in array "but" via stageMc.addChild(section1), but instead of tracing "section1" I get "instance1", and of course stageMc wont advance. I guess what I'm asking, is whats the diff. from a functional standpoint if I embed the clips in flash, or embed them into the stageMc clip via the display list? what am I missing? FYI, this code works, so long as i place the assets on stage myself. But I want to add the btns via the display list, and i can add them, they just instanciate wrong?

ActionScript 3.0 :: Using Variable To Remove Child From Stage?

Sep 18, 2010

I'm trying to use a variable to remove a child from the stage and I get this error:
Scene 1, Layer 'action', Frame 108, Line 471067:
Implicit coercion of a value of type String to an unrelated type
flash.display:DisplayObject.

What I'm trying to do is to link some keys to add movie clips to the stage. But I need to have only one movie clip at the time on the stage, so, if I press a key to add a movie clip on the stage, the one that is already there needs to be remove. So I set a variable called "actualConf" to hold witch movie clip is on the stage. I simplified the code a bit to add it here (If I press "Q", the movie clip "lise" is added to the stage, then if I press "W", I want the movie clip "lise" to be removed than "nancy" to appear), I added a comment where I get the error :

Code:
Select allstop();
var actualConf:String = "null";
var lise:mcLise;
var liseX:Number = 50
var liseY:Number = 50
[Code] .....

Because I will have about 15 keys linked to 15 possible movie clips, I don't want to use the "if" condition 15 times.

ActionScript 3.0 :: When To Remove Child - Sprite To Stay On The Stage Until One Of Two

Dec 16, 2008

I have a map with various regions as movieclips. When you mouse over a region, a sprite appears containing xml data. Among this data is a hyperlink. I want the sprite to stay on the stage until one of two
things happens:

- you mouseout of the sprite
- you go to a new region

That seems to be the problem. I've successfully coded the program to remove the child if you mouseout of the sprite. But if you go to a new region, it makes a new sprite and now you have two sprites with xml data on the stage! If I remove the child when you mouseout of the region, then the sprite won't stay on the stage for you to click the hyperlink. How can I make the sprite stay on the stage until:

- you mouseout of the sprite
- you mouseout of the region IF you aren't on the sprite

Class :: FLA File - Adding Child To Stage

Apr 12, 2012

I am trying to make a "Achtung! die kurve" - like game in Actionscript 3.0. So far I've done the movement of one of the 'worms', and it works alright. I wanna divide it into different class files, but I can't seem to get it to work. I have a .fla file and 4 .as files. So far I only have code in two of these. When I put all my code directly into the fla file, it works perfectly fine, but when I put it into my player class, it won't 'add the child' to the stage. Here is my player .as file: [URL].

The reason why I commented the addChild, is because I wanna do this in my mainFile.as. This is from the main file: [URL]. I'm not quite sure how to call it in the main file, so I'm guessing that this would be the issue. All the files are named and placed correctly in the same folder, and flash says that each of my .as files are targeting the .fla file, so this doesn't seem to be the issue. How I can change the speed of my sprite.

ActionScript 3.0 :: Delay Adding Child (Movie Clip) To Stage?

Dec 15, 2011

I am attempting to add a movie clip to the stage when a button is triggered. When the user clicks the button the movie clip is added to the stage; it works fine, but the following problems occur:

1) The appearance of the movie clip is delayed.

2) The sound in the movie clip starts to play but the movie clip appears when the sound is finished.

Additional information: 1) The movie clip has the sound in the timeline.Here is the code:

Actionscript Code:
//Buttons: Adds movie clip to stage.readtomeShortA1.addEventListener(MouseEvent.CLICK, playShortAReadMe1);var playShortA1:ShortAReadMe1function..[code].....

2) However, I also want to know is keeping the sound in the timeline of the movieclip the most efficient way to use sound in the movieclip? Or is there better, more efficient way to do it?

ActionScript 3.0 :: Adding Menu Popup Child And Tween Off Stage

Sep 30, 2011

I have several objects on the stage and a MouseOver on any of these will add a menu popup child and tween it from off the stage. A MouseOut will tween the menu away and remove the menu with removeChild. Heres the bug: If I mouse out and then quickly mouse over the same object while the menu is tweening away before it has been removed, it doesn't add the menu again, and then on the next mouse out, it tries to remove the child menu, which isn't currently a child because it was just removed, and

I get the error:
TypeError: Error #2007: Parameter child must be non-null.
at flash.display:isplayObjectContainer/removeChild()
at menucaller/tweenOffTimerEnd()
at flash.utils::Timer/_timerDispatch()
at flash.utils::Timer/tick()

Is there a way I can use an if statement to make sure that the menu is a child of the parent before removing it?

trace(child.name)

What I am noticing is that it will return everything until it runs into a symbol that does not exist on every frame.. as soon as it does encounter a symbol that does not exist on all frames of the main time line it spits out -
