ActionScript 3.0 :: Moving And Removing Object References
Aug 18, 2009
I have a 2-dimensional array of Objects. Their location in the array determines where they appear on the screen. When I want to move an object down, I am trying something like this:
[AS]LocationArray[i][j+1] = LocationArray[i][j];
LocationArray[i][j] = null;[/AS]Of course, with the way AS3 handles objects and references, it removes the object completely. How can I simply move a reference (or remove an reference) without destroying the object?

I'm writing an application where I have many objects (data models) that are identified by a unique String ID that every such object possesses and these objects can refer to each other by their IDs.So far so good but now I need to keep track of which object keeps a reference to another object and of course there are cases where an object references (or is referenced by) more than one other object and I was wondering what would be the best method to store these references? In a simple map data structure I could just map one object's ID to another but as mentioned there are cases where an object can hold a ref to an arbitrary amount of other objects

Does anyone know if it's possible to list the references an object currently has in ActionScript3 (e.g. listeners, children etc)?
I'm trying to clear an object from memory ready for garbage collection but for some reason it's hanging around.

I am trying to create an object that is handling the events of different objects. The object is created in the 1st frame of a code layer:
ActionScript Code:
var gImageEdit:ImageEdit = new ImageEdit( imgAction, movImageFront,
movToolbar.btnZoomInImage, movToolbar.btnZoomOutImage, gZoomSound );

I'm just getting to grips now with how the Garbage Collector works.
Is there a way (like a function or a custom class available somewhere) to check an object for all its references and return them so that you can see what it's connected to?

* Is it possible to create weak references to objects (like theventListener/EventDispatcher is able to do) so that if they are removed, you won't be stuck keeping a reference and taking up space to something that should be garbage collected?* Is there any way to find out how many active variables are referencing a certain object? This would be handy to actually create weak references, since, if you for example, have a static array containing all objects created in that class, you can do a regular check to see if there is only one remaining reference, and if so, you can safely remove it.
* Also, might there be any way to list the entire space (one big chunk of binary data, most likely) of every variable currently running in the program, all references, basically, what Flash is currently storing in RAM?I'm pretty sure that Flash (as crappy and lacking as it is in so many areas) does not have anything like any of these built in, but hopefully there is at least something.

I want to do is create several arrays to hold groups of movie clips (i am using as buttons) which have similar functions so that I can add event listeners using a for loop statement rather than making a huge list of add and remove event listeners.I have seen this method working before but I cannot get my code to work!! This is probably a very noob concept but I have been struggling with it for hours.Ok, so in the extends movie clip bit on my as file I declare the array as such:public static var controlBtns:Array;Then in the initializing function I put values into the array as such: [code]The trace seems to output all the object names (as they are listed in the library) and then I get this error: TypeError: Error #1010: A term is undefined and has no properties.Which is kind of obvious as I cannot seem to access the movie clip instance names that I have set up in the array.I tried putting quotation marks around the names in the array making them strings but then I can't access properties of strings - which is obvious enough to.

I have a bit of a memory leak issue in my Flex application, and the short version of my question is: is there any way (in AcitonScript 3) to find all live references to a given object? What I have is a number of views with presentation models behind each of them (using Swiz). The views of interest are children of a TabNavigator, so when I close the tab, the view is removed from the stage. When the view is removed from the stage, Swiz sets the model reference in the view to null, as it should. I also removeAllChildren() from the view.
However when profiling the application, when I do this and run a GC, neither the view nor the presentation model are freed (though both set their references to each other to null). One model object used by the view (not a presenter, though) IS freed, so it's not completely broken. I've only just started profiling today (firmly believing in not optimising too early), so I imagine there's some kind of reference floating around somewhere, but I can't see where, and what would be super helpful would be the ability to debug and see a list of objects that reference the target object. Is this at all possible, and if not natively, is there some light-weight way to code this into future apps for debugging purposes?

loading external SWF's and its class files hanging around after the movie is unloaded....Its kind of tricky to explain, but you can see it very clearly in this file... http:[url]...Just run the main_stage.fla within flash [mx 04] and you'll see that if you click "Tester A" it will trace out "My Name is Tester A", then if you click on "Tester B" it will load a different swf, with a different class, but still trace out "My Name is Tester A" when it should be "My Name is Tester B"....
I have tried, unloading the swf's, removing the mc_Dropper and re-attaching it, re-declaring the variable testObj as null before declaring the class,

I am a new flash developer and I cannot seem to understand this problem. Whenever I try and trace one of these variables of type XMLList they all return NULL except for the last one in the array.The createDatsSets() function is designed to pull XMl data and copy it to an variable of type XMLList which resides in an array. This should happen 8 times to add data to all 8 variables.It works fine with a single variable but, in the for statement when.I try and trace any of the variables in the xmlList array only the last one has XML data in it.

I'm trying to get my head around optimising AS3 code and clearing things out for garbage collection.
I understand that each time an item is referred to in the code it has its reference count increased by one, so I was wondering if there is a trace option I can use to see how many references each of my objects has?
I can then see where things are getting left behind (if they are) and where I can make optimise better.
I think it would help me work out several issues if I was able to do this

I am trying to do a apply a tween for the width property on a MovieClip Object but every time it changes the width and the position too, and I don't want that. I want to change the width going to one side without changing the x and y of the object.
I tried both of thes and they gave the same result.
var c:Tween = new Tween(left, "scaleX", Strong.easeOut, 1, 1.5,20,true);
var c:Tween = new Tween(left, "width", Strong.easeOut, 20, 200,20,true);
I think it is applying the transformation according to a center of the movie clip. but I don't know how it can be changed.

Im working on a small project and it involves a guy which you move with the arrow keys. The arrow keys add to his x, y velocities and his position is updated accordingly. How can i get this man to grab onto an object and spin around it (like when you grab pole and letting your momentum swing you around) . I can make him grab the object but I dont know how to modify his x,y speeds to simulate the arc.

I was thinking if there was a way to remove the shared object pop up from popping up lol?Its because Im making a game where when the player saves the pop up comes up over a 100 times and it's really frustrating, so I was thinking if you could remove the pop up entirely by using actionscript?I've found a script that shows the popup:System.showSettings(1);So is there a way to reverse this script? like System.hideSettings(1); ?

I've made a little movie that reads items from an XML document and when you click on a thumbnail it adds the details and the price to a list and totals the amount. The problem I'm having is when you want to remove an item; I want to make it so that the items all shift up and there isn't a gap in there but at the moment they're overlapping sometimes when you remove something from the middle of the list.I'm not really sure where the problem lies because I've been staring at this for a few days now nothing's coming to me. It's probably in the below area, I think it's going haywire when the array gets remade but the num property of the remove button doesn't get updated.[code]I've attached all of the relevant files if anyone wants to take a look at it in action. Also, I know some of the code might seem a bit strange (like reading the XML in a loop and then pushing that into a different array) but there is a reason for it, I've stripped that part of the application out though.

I am having some problem removing a null object and I realise that I have not been unloading my swf's properly. Could someone take a look at what I have been doing and tell me what I can do to make it better. I am putting my website in an exhibiton of my design work and if it lagged up due to all the clicking it would suck! so its important.
Code:
aboutBtn.addEventListener(MouseEvent.CLICK, aboutLoad);

I have an item that I want to appear on stage (see code below); but only for 5 seconds. After 5 seconds I want the object to disappear. I know that I can use removeChild to remove the object, but I don't know how to keep the object on the stage for a specific amount of time.
Here's the code:
stop();
//Add a movie clip to stage

I have written this little script, as i want to remove some of the text fields that are currently contained within the Display Objec, however it does not like to see the TextField as a varaible name. How would i convert the object from an array to become a textfield that can be removed, after being added through
addChild()
This is the script
var delayHeading:Number = 1500;var repeatHeading:int = 1;var setShow:Timer = new Timer(delayHeading, repeatHeading);setShow.start();setShow.addEventListener(TimerEvent.TIMER_COMPLETE, maybeLater);

I have a problem in ActionScript 3 with a project where I am to output a bunch of data in a diagram and as pure text. This is not the problem, though. The problem is that when the user changes the type of data he wants shown. I would then remove the currently shown columns in the diagram, and add new ones. But my code removes ALL columns, so that there is no diagram at all!
I've done it all in Flash CS5, and the columns are instances of an object I made (a rectangle) which I just add to the stage. All the instances are added to the container "container." When I want to remove them, and add new ones I use:
var container = new Sprite(); // The container for my diagram
function emptyContainer() {
if (container.numChildren > 0) {
[Code]...
I wonder where to place my function for removing all children, to remove just those children that were added earlier. To matter where I place the function (at the start of fChange, at the beginning of each case) there is NO diagram shown, either new or old.

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.

I have problem closing or removing a netstream object. the object is created in a class I wrote. that class is added to a sprite object. when I remove the sprite which the netstream is a child of the netstream still plays. I know I can use close() to close the netstream but the problem is that the object that removes the sprite does not know that there is a netstream object in the sprite.

When I use parent.removeChild(this) it works, but throws out these errors: TypeError: Error #1009: Cannot access a property or method of a null object reference.
The object is supposed to remove itself when it ran out of energy.

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