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'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
View 1 RepliesI 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.
View 8 RepliesI 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?
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?
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.
View 4 RepliesI'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

so i want to have my dynamic text listed with a consistent space between each textfield. However, the textfields can have varying amounts of text, so just doing txt.y = t*40 would not cut it. I've tried getting txt.length to calculate how many lines it would be, but if i change the font size it changes everything.
View 2 RepliesWhat im trying to acomplish is to list some mcs by pressing buttons.I got 5 buttons and 5 mcs.If the user press for example 3 buttons the objective is to list that 3 selections in same selection order and if the user deletes the 2nd of the 3 selections the 3rd selection takes the place of the 2nd selection (a population list). I attached a link to the source file.

I have lost the AS 2.0 Class file for this script, can someone look at my flash file and see if you can get it to work? this program list stores for a company, the drop down menu serves as a selector for the states and the scroll box list the stores.ive been trying for 3 weeks now. the script reads external text files to show the information.

I am basically creating an application that prioritizes jobs listing, so far I can assign a task priority, description. So basically once the task description and task priority is chosen, the user will click the add button, and this will be stored in the database and on the screen another mc will appear where the created priority and description assigned will be display. In the mc there will also be a delete button to remove/delete the task. What code could I use to remove the task...
So far I have typed the following
mc.task_mc.delete_btn.addEventListener(MouseEvent.CLICK, onDeleteClick);
private function onDeleteClick(e:MouseEvent):void {
}
I just wondered, what is the benefit of listing each class in imports separately instead of using a wildcard?[code]Is there any benefit at all?

I have an API for a flash player that I want to use, but it is closed source. I know I could try a decompiler but I need to see what it loads and what it's doing at runtime.I'd like to see the objects (and all their info) that it loads and has on stage along with thier instance names. I'd like to see what this SWF has/does so I can write my AS3 code accordingly... maybe add some additional event listeners.Is there any was to go about doing this? I know there's some AS3 commands to get this information but I dont know what they are.
View 1 Repliesi'm trying to create some code which would create instances of arbitrary classes.for example... i'm making a game which will be hosted on a site, and characters i create over time will eventually be selectable for use in game. but instead of uploading an entirely new game whenever i decide to add a new character, i'd prefer to just update an xml file listing the characters, as well as an swf file for each character class.so during actual runtime, i'd have to create instances of these characters.... but i wouldn't necesarily know which character class constructor i'd be creating.... it would depend on who the user selects.if it were up to me, i'd be able to decide what class instance i'd like to make from a string variable (taken from xml).like this maybe...
var classname:String = "CharacterOne()";
var character:Object = new classname;
....instead of having to write: var character:CharacterOne = new CharacterOne();
