View 9 RepliesActionScript 3.0 :: Object Does Not Show On Screen Once Re-added To Display List?
Nov 3, 2011I have an object that is instantiated, then placed into a property within a singleton (single instance) object. When a button is clicked an event is dispatched carrying a payload that references the display object that is held within the Singleton. When the event is heard, my view object adds the object to the display list e.g. addChild().The Item shows. Now If I hit another button an event is dispatched, and a new item is added to the display list via the method above and is seen. The 1st object is removed from the display list Here is my problem. When I click the button to load the 1st Object the above process is executed again but the object does not show.
I can run trace statements from the object that is supposed to be visible and they run fine. I even do a check to see if the visible property is set to true, and it is, but not object is on my screen. Code for this process.
//custom event carries the name of the page aka display object. this is a string
dispatchEvent(new MenuEvent(MenuEvent.CHANGE_VIEW_STATE, event.payload));
//When the event is heard, the following condinial is run

ActionScript 3.0 :: Remove Object From Display List And Memory Which Added Dynamically
Aug 22, 2010how do we remove object( sprite which has an external swf as it's child ) from display and more importantly from memory yet we still can use the same variable to add another object (yes another sprite like the one we removed yet has different content).., "
i did tried the removeChildAt thing it did remove all the child from the display list but i still can hear sound from video running.
here is small scale code of what i'm doing (sorry that i can only give you chunk code of loading and adding)
// var SWFList:XMLList; //used to hold a list of all external swf source,atribute and etc// var totalSWF:int; //hold the total number of external swf there is to be loaded
// var swfLoader:Loader; //instance of loader class used to load the external swf

ActionScript 3.0 :: Display Object Cannot Be In The Display List More Than Once?
Feb 9, 2009It's my understanding that a display object cannot be in the display list more that once.So if I add something to the stage shouldn't a second addition of the same object replace the first? for instance:

there should now only be one "myDisplayObject" on the stage.
ActionScript 3.0 :: Nothing Is Being Added To The Display List?
Jan 20, 2010I've got MovieClips on the stage, both manually added, and added with code. I used this code to trace them all:
for(var i:int=0 ; i<stage.numChildren; i++) {
var myObject = stage.getChildAt(i);
trace(i);
trace(myObject);
}
All it returns is 0 and [object MainTimeline]. Is there something wrong with Flash, or did I do my coding wrong? The objects I put on the stage should be on the Display List, right?
AS3 :: RadioButton Label Changes Visibly When Added To Display List?
Sep 14, 2010I'm instantiating a group of RadioButton components into a Sprite and then later adding it to the display list. When the latter occurs, I can visibly see the font of the RadioButtons' labels changing from a serif to sansserif—but I have NO code to that effect anywhere. This occurs long after the components are actually instantiated, when they (via their parents) are added to the displaylist.
In Question_UI.answersContainer.answer:
answerUI = new RadioButton();
answerUI.group = rbg;
answerUI.label = text;
[Code]....
I've triple-checked the obvious, but there's NO code regarding the font of the label at all. It seems to only have to do with being added to the displaylist.

Flash - Sorting Display Objects By Their Display List Depth
Aug 5, 2011I have a list containing display objects from throughout the application (insertion order). I want to process the list either top-down (parent, child) or bottom up (child, parent). The only requirement is that either a parent is processed before any child or vice versa a child before its parent. What is a good approach? This question is not about sorting a list. It's about retrieving the depth of a particular display object.
Example
Display list:
A (root)
B1
C1
C2
D1
B2
......
My list:
list = [E1, F4, A, B2, B1, C3, ..., N9, N8]
Bottom-up:
N9, N8, F4, E1, C3, B2, B1, A
Top-down:
A, B2, B1, C3, E1, F4, N9, N8
Does not matter if N9 before N8 or N8 before N9. Important is that any N is before M (first run) or any M before its children N* (second run).

Actionscript 3 :: Dispatching From An Object Not In The Display List?
Feb 24, 2011I have an object that controls another object that is on the display list.
The setup looks like this:
Parent (Main Timeline)
- Child

How can I get this event to reach the parent?
Actionscript 3 :: Removing Object From The Display List?
May 10, 2011I have an application that uses a main class to control other MovieClips, adding and removing them as needed, most of them are separate screens or sub menus.
When I leave the main menu and come back to it later from another screen, certain animations and roll over buttons still play, which I don't want, I basically need the main menu screen to reset every time it is seen.
I read up on this and found out that removing the child doesn't necessarily remove it from the memory.
I tried setting the mainmenu to null before moving onto a different screen but this threw up an error, stating that the parameter child must be none null.
how to completely kill my mainmenu when it is not needed.
public function confSubMenuOneScreen():void {
subMenuOneScreen = new SubMenuOne();
mainmenu = null;
[Code].....
This is the example of code that removes the menu and adds another screen, with the mainmenu = null code that throws up the error.

ActionScript 3.0 :: Target An Event At Object Not In The Display List?
Jun 7, 2010I'm trying to dispatch a custom event from a custom class (which implements IEventDispatcher) to another custom class (also implements IEventDispatcher) but I cannot trigger the corresponding event handlers.The classes are instantiated at different parts of the application: one on the main canvas and the other on the back-end (data side) of the app. Neither of these is part of the display list hierarchy and I need them to communicate through events.I've looked through adobe docs, the web and Mook's Essential AS3, but have come up with nothing...
View 4 RepliesActionScript 3.0 :: Accessing A Non-display List Parent Object?
Jul 12, 2009I need to access a non-display list top-level (Parent? Ancestor? What's the correct term?) object from a display list object, and I don't know how.
In my code, ResultX is an instance of my custom class Result. Card is a sprite, a visual representation of the ResultX object, defined inside the Result class and attached (or removed) to the stage via a separate function inside the result class as needed.
I want to refer to the correct Result object when the user clicks on the corresponding card to call a function there. In accessing the sprite manually, ResultX.card works fine, but I don't know how to go upwards trough the path - card.parent (or actually target.parent, since it's done via event) just returns Main, of course.
ActionScript 3.0 :: Bring Object To Front Of Display List?
Dec 8, 2009I'm trying to create an image class that I can reuse throughout a website I'm making.
When you click an image i want it to expand to fill the screen. When this happens obviously it will have to be at the top of the display list so that none of the other objects on the website are above it. The problem is that I want to be able to use this class throughout the website, even within containers that are beneath other objects so it seems impossible to simply bring it to the front easily?
Edit: Maybe when you click an image it would create a replica on top of the current image but above all the other objects on the main stage - then expand that one instead of the original image in the container? Theres got to be a better method though... I can't imagine this working too smoothly.

ActionScript 3.0 :: Display List Manipulation Removes Object From Frame?
Nov 16, 2010I've got these Flash students I TA for a course, and they are doing drag and drop exercises and have come across some weirdness.(They are using a frames based design to represent different pages of activity, with a menu to goto each frame under user control.)At author time:
1. they set up drag and drop as3 for an object on a particular frame.
2. when startDrag is initiated, they moved the dragged object to the top of the display list, so it appears to float above all other objects as the user drags.
at runtime,a problem appears:the object seems to have been pulled out of the frame, and now floats in a display list above any frame that may be advanced to.What's going on here? It's like the object got pulled off the authortime stage and now is disconnected. Going back to the drag and drop frame shows the original object again, reinstanced, along with this copy that got pulled out.

ActionScript 3.0 :: Display 1 Display Object Many Times?
Aug 14, 2009Can you make one Bitmap Object (I'm using an external jpg) or something similar, and then display it many times simultaneously without creating a separate object each time?
Also, would they be easily removed or hidden?
I've got a little checkmark jpg graphic loaded here, but I'm not sure how to go about using it in many places at once.. I can only display it in the one place at any one time...
I'm thinking there might be a way to load the picture once, then use its bitmapData elsewhere in new display objects somehow, without needing to reload the image over and over?
