ActionScript 3.0 :: Need To RemoveChild() And AddChild() In Order To Force Image Update?
Sep 1, 2011
Here's some code I created as an answer to another question. It pulls a library item out of the library and puts it on stage programmatically. No big deal, except that in order to get the image displayed on the screen to actually update, I had to removeChild() and then addChild() it back. Is there another way to force the screen to redraw?
[Code]....
Note that in this example, this code is on frame 1 of the timeline. It _feels_ like imageClip is not a direct reference to the thing that's actually on the display list. However, when I modified my code to replace the reference to the AS variable imageClip with a more direct reference to the element on the stage (imageClip = getChildAt(1)), that made no difference either.

somewhat understood the basics of adding and removing children, however, I am facing another problem. After using the removeChild Function, I can't seem to add another child.For example:
ActionScript Code: var attachedMC = new (getDefinitionByName("Content1") as Class)() Page.addChild(attachedMC);
I create a custom component to override the linkButton to make it behave that if an exist value is found, it would shown as "Added".
By default the button label is "Add to cart", I could not make the button become "Added" after trying many trial and error on uHandler which I suppose, COMPLETE, ENTER_FRAME, CREATION_COMPLETE could not even update the label.
public class Btn extends LinkButton{ public function Btn(){ super();
i have a swf with several processor intensive subroutines within a main init() routine at start up (about a 5 secs startup wait). it needs a preloader not due to asset loads but to the processor intensive routines.i'm trying to create a preloader that will display progress as the routines complete but when i try to write text to text field as each subroutine completes either the textField.text is not updated or the text field display is not updated after each subroutine finishes.this prevents me from tracking the progress of the start up.
is there a way to force an update to the display list in the middle of a processor intensive routine? i believe flash is supposed to update after each frame but i'm not seeing this.also, the text field i'm displaying *before* this processor intensive routine *does* display when running locally but *does not* display before the routine when running online.not sure why.
For example, I have a function that is triggered by a button click This function loads an external swf.I then set a global variable swfLoaded to true, with the idea of having an if condition that executes removeChild(loader) if swfLoaded is true.When trying to execute removeChild(loader), I get an error telling me that it must be the child of the caller.I've seen the code below, which loads a default swf, but I don't want a default swf - I just want one loaded if the button is clicked, and then if another button is clicked, the original one to be removed before the next swf is loaded.How do I make this code work without loading a default swf, just loading one once someone clicks a button, and then removing it?
var Xpos:Number = 110;var Ypos:Number = 180;var swf:MovieClip;var loader:Loader = new Loader(); var defaultSWF:URLRequest = new URLRequest("swfs/eyesClosed.swf");
I need help with addChild and removeChild.I want to make a two buttons one addChild and other removeChild . Friend helped me a little bit, but I didnt uderstand the script ;]Here is the example script which my friend gave to me. In other words I want to make a button that attached hair and the other that removes.
ActionScript Code:public function changeHairs (newHair: Hair): Hair { Face.removeChild (oldHairs);[code].....
I have a MC that the mouse can drag and slide, when it gets removed from the stage when it hits an out of bounds object. I re add it to the stage at the x,y position it originally started from but when I re add it it continues to slide in the direction it was going before it was removed.
I'm making an application for the iPad that allows me to swipe movieClips that are 1024 x 768.The application starts with movieClip1, movieClip2 and movieClip3 added to the stage.When you swipe to the left... they are to move to the left. When a movieClip is off the stage to the left... I want to removeChild and then addChild the next one in the queue to the right of the visible clip. This will provide a seamless swiping experience.
I first noticed it when this function started throwing a 1009 error:
[Code]...
were throwing the 1009 error. Which is wierd on two accounts. First, if I remember right, error 1009 comes about when referering to an object that is not on the stage. Which makes NO sence when getting it from an addChild! Second, this error only starts to occur the second time I use the function.
I am putting together my file right now which is now using visual elements purely added and removed via AS3 (addChild / removeChild) methods.My question is just about the proper time / place to declare their variables.Can I declare them all at the start of the movie (frame 1) and just call them when I need them, or is it better to declare them on the frames that they are introduced on? I guess the question is really, will I ever lose those variables throughout the movie once they are declared?
I have images loading into a single mc container every time i click a button. The images are being loaded (from xml data in a data grid) on top of each other every time the button is clicked. This is the latest Ive been working with and doesnt seem to work
Loader();var reqImage:URLRequest=new URLRequest(data_grid.selectedItem.JPG); imageLoader.load(reqImage); if (imageload.numChildren>0) { imageload.removeChild(imageLoader); imageload.addChild(imageLoader);
as you guys can see it addChild with dynamics and its not hardcoded. difference between adding a movieclip from the library and loading a swf external?
because i cant get this to work. Even tho my code does addChild and removeChild i get error-messages in the output. The movie works fine but it isin't a pretty code

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 have a ball MC that is a child of a ship MC, and when the ship fires the ball I need to make the ball MC a child of the stage instead of the ship. Here's the code I have (contained in ball.as, this function is called when the ball is fired)
public function prep():void { ship.removeChild(this); screen.addChild(this);
I have 8 movie clips. They are set up to disappear when clicked.on (release) {this._visible = false;}The problem I am facing is that I want the movie clips to be clicked in a certain order, so mc1 has to be clicked (and disappear) before mc2 can be active and click-able. That way the user has to click on them in order for them to disappear.

I would like to know the internals of that method, in other words what exactly happens when I call that method. If someone can explian it with a list 1,2,3... would be great. including events..
I'm in the right place for this plea from yet another novice trying to learn AS3 in Flash with a couple of very good books but no one to talk to about it - and in danger of losing hair in the process.
My problem: I have a web site containing 8 pages. Each page is a separate movie clip, and each is in a Labeled frame. My intention is to have an overlay for each of the buttons in the top left panel of the home page. On the positive side I have managed to achieve the dynamic placement of an instance of a library movie clip called "sampleAR" via addChild to overlay on top of my home page. But I can't for the life of me get removeChild to rid me of the wretched thing again. My home page is in frame 1 of the movie labeled "Home". This contains a movie clip with the instance name "HomePage" on the stage. Inside the "HomePage" movie clip is my script sitting at the end where the movie stops in frame 44. The code sits here because this is the only place I've managed to get any kind of result with the following code:
I'm trying to make a basic mouesover and mouseout that will display a help/key box on the screen. I created the help box that will be displayed as a symbol called helpbox. I updated the linkage to export to Actionscript and called the class Helpme. The object I'm using to instantiate the Helpme class is a small graphic called helpcoast. I want the "helpbox" in the new class "Helpme" to be displayed only when the mouse is over the helpcoast graphic. When I test the movie and mouse over and mouse out of the graphic once, I get no errors, but if I mouse over it, then off it, then back over again, I get this error in the output box:
How do I make a photo gallery that up dates by itself its contents getting it from a folder and putting then in order? The pictures when clicked should load a swf with information about the tittle.
I have a movie on stage that acts as a button using the code. person_mc.buttonMode = true;
I load an image onto the stage from my library using addChild(holiday);
What happens is that the person_mc button I have on stage will not function anymore, because I am presuming it is underneath the holiday pic when I loaded it using addChild.
How do I load the holiday pic, so that it is underneath the person_mc?
I know I could do what I did with holiday using addChild for the person_mc, but I do not want to do it that way.
loading 2 external swfs into one main file using 1 preloader, I have figured out how to get the preloader to handle the correct # of bytes loaded and such but my 1st swf I want to load onto the stage is a video file and I want it as the background but I don't want it to start until after they are both (the video and main file - 2 external swfs) loaded and then I want to start the video and place it on the stage first, then place the main swf on the stage.
I can get the order right if I place them into my load complete function but then my buttons don't work on the main file.
Here is the code:
var bytesLoadedVidBG:Number = new Number();var bytesTotalVidBG:Number = new Number();var loader0:Loader = new Loader(); // load video BGvar loadedSWF0:Object;loader0.load(new
I created two empty Sprites to serve as layers, bottom_spr and top_spr. When clicking a button, a MovieClip appears and follows your mouse, until you click, then its position is fixed. As soon as the button is clicked, I addChild the MovieClip to the correct Sprite. Unfortunately, the layer system doesn't see to work, because they are layered in the order I place them, the Sprites don't seem to influence it. How is this possible?
private var ground_spr:Sprite; private var units_spr:Sprite; public function Game() { addEventListeners(); ground_spr = new Sprite(); [Code] .....
In my case, some user interaction produces new values for the bindable variables "someDataProvider", and "someSelectedItem". However, when flex renders the DropDownList, the control's selected value is empty.
The reason for this is that the DropDownList's "selectedItem" property gets bound before the "dataProvider" property. The "dataProvider" needs to be bound first for "selectedItem" to be valid, this is because the new "selectedItem" points into the new "dataProvider".
what is the best practice for updating bindable properties in a specific order? I've come up with a few ways (e.g. using a valueCommit handler), but I wanted to see what the community had to say.
I have a main class that calls and removes screens with addChild and removeChild, these screens are movie clips.My issue lies in these movie clips, each clip is linked to a class - e.g. confidence.as links to my confidence screen.I am trying to add buttons and pieces of text from this class file onto the confidence screen, so essentially adding more movieclips on top of a movieclip that has already been added. I keep getting this error:TypeError: Error #2007: Parameter child must be non-null.I could do with some help figuring out how to add objects to my screens, as I am trying to prevent having everything in one class.
