ActionScript 3.0 :: Remove Object From Display List And Memory Which Added Dynamically
Aug 22, 2010
how 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
I 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
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?
I'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.
I am overlooking something, but why won't my FLVPlayback component, which is in my library, be added to the display list? When the code executes, there is now FLV component on stage.[code]...
I am getting problem of memory of having repeating object. Below is my code.
import flash.system.System; var counter:Number=0; var systemMemory:TextField=new TextField(); systemMemory.x=200; stage.addEventListener(Event.ENTER_FRAME,showNext); function showNext(event:Event){ [Code] .....
Above code does repeat textField Object continuously. Now I want to destroy previous created textField Object. So that my memory will not be hang. I got some where in the blog that with System.gc() could clear garbage collection. But currently I am not working with system.gc any more I want to clear previous object in programatically way. Is there any way that I could destroy previous created object?
I'm using a Timer to load a different swf (into Sprite) every couple of seconds, it works great but I can't get the previous swf removed before the next one loads, heres the code (I know, its really basic)
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)?
It'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:
[code]...
there should now only be one "myDisplayObject" on the stage.
I'd like to remove a child of the display list if it exists before adding another to the stage. This gives me Error the first time I call it because 'myMC' doesn't exist.
HTML Code: function callMc(){ if(myMc) removeChild(myMc);
I'm doing quite a complicated game with a lot of code but one thing I can't quite figure out is how to trigger a function on the main stage from a dynamically added object.I've tried using custom events, but it doesn't work and doesn't throw any errors either.Here's the code for the CustomEvent class:
Code: stage.addEventListener(CustomEvent.CUSTOM, checkMoney); //more code here function checkMoney(e:CustomEvent)[code].....
All of the above seems to work, because it doesn't throw an error, but it doesn't trace money when the event is dispatched.Before you ask, the event IS being dispatched or at least the if method it's in is entered.Any other method to tell the stage it's time to run the function is welcome also
I realized that if I do addChild, I can't really see the dynamically added component, since flex did not reserve space for my List to display. So I do parentDocument.addChild, and then it appears no problem. My question is since it's being added in the parentDocument, so it is suppose to be a component belong to parentDocument, so is that component still be able to call this handleMouseDown? From my experience, it's still able to, but which doesn't make sense to me. Can someone explain a little about why it can still work, or any better approach other than parentDocument.addChild
i have this really basic class and all it does is create a button...i have another class called main where i want to put the button on the stage...problem is it all compiles but can't get the button to display..
public class Main extends Sprite { public function Main() {
Is there a way to make a display object always be at the top of the display list?For example, I know you can set the childIndex, i.e:setChildIndex(myDisplayObject, numChildren-1);But is there a way that an object has sensed that something else has been added to the display list and restack themselves accordingly?
When a movie clip is removed from the stage it's properties are still accessible including visible == true. How do I test to see if it is off the time line?
I 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.
Any command to check whether an object is currently present in the Display List? I have a TextField called _startHereText. I have some logic where I need to sometimes use RemoveChild to take this object out of the Display List, but I first need to determine if it is presently there.
For some reason below is not working. It is probably very obvious but I am not seeing it. As soon as I comment out the container mc variable and just add Child to root timeline I see everything which means me container is not being added to the stage correctly.
stop(); import flash.display.MovieClip; var i:int = 0; var a:Number = 10; var ageString:String; var ageText:Array = new Array(); [Code] .....
I'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...
I 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.
I'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.
