I am dynamically generating buttons and textfields using an array and a for loop ... It all works well and creates buttons and textfields ... but once they are created is there a way I can cast them to a movieclip so that i can then control the visibility etc.
Here's the code:
//define variables
var _buttons:Buttons;
var _buttonsX:Number;
var _buttonsY:Number;
[code]....
I've had a problem for awhile that was really odd. After some intense debugging, I realized the problem lied in setting an array equal to another array.[code] When setting one array equal to another, the values aren't copied over, but a reference to that memory is stored. So no matter which variable you change, they are both references to the same memory and thus both will reflect the changes.With other data types, this doesn't happen.I could fix it by looping through t1 and using push() to add each index from t1 into t2, but that seems a little messy.

THE CODE ABOVE DOES NOT WORK ,I want to create 10 moveiclips each with unique name, which I can move around or maybe load things into later. At the moment the trace returns 'undefined' so the movieclips aren't even being created.
I am running into some trouble adding an array into another array to create a multi-dimensional array.The code appears as below:
var slideDataArray:Array = new Array();
var slideShowDataArray:Array = new Array();
slideDataArray[0] = xmlData.SlideShowParameters.SlideShowImagesDirectory;[code]........
I am looking for a means of placing the slideDataArray into a 'slot' or value of slideShowDataArray so that I can in the end pass the slideShowDataArray as a parameter to another function.As of now, the last slideDataArray appears 11 times (the loop runs 11 times) in slideShowDataArray and the way the code is written the slideDataArray is unique every iteration of the loop.
I've got a bit that loads a big chunk of xml data about products.I push product info into an array(e.g. productArray), then add that array to another array (e.g. allProductsArray)How do I sort those arrays? For instance, if I want to sort the allProductsArray based on the info in productArray[0]?Alternatively, would something other tha an array of arrays be a better route?This loader loads the same sort of info for many different clients, so the bit to sort on will change.
View 5 RepliesI'm trying to write a function where I can specify any amount of array, and the return value will be an array containing the contents of all of the specified arrays.I've done this, but it seems like a really slow and ugly way of doing it:
var ar1:Array = [1,2,3,4,5,6,7,8,9];
var ar2:Array = ['a','b','c','d','e','f','g','h'];
function merge(...multi):Array[code].....
Is there an inbuilt and more efficient / nice way of achieving this? The result does not need to be in the same order as the input - completely unsorted is fine.
A little explanation: Im making a random arranging number Array. So instead of using a loop and assigning 0 to first array element, 1 to second, etc.I need to make it totally random but without repeating any numbers. To do that I made a second Array that will have the same number of children to serve as a reference.Each of them will be an Object with a property "num" , wich will be its actual number, and a property "called" wich defaults to false.Like this:
ActionScript Code:
for(var i:int=0;i<vQuantity;i++){
ranArray.push( new Object() );

correct syntax for pushing variables to arrays within arrays? I have searched many threads but found nothing that exactly answers my query.I have a class (Brigade) which amongst other variables contains an array (BrigadeUnits) This is the third element.. My Brigades are stored in an array called AllBrigades. I now need to fill the BrigadeUnits array with objects of my Units class.The hierarchy I want to create is as follows:
AllBrigades (array of Brigades)
Brigade (object)
BrigadeUnits (array within Brigade object)
Unit (Object to be stored in BrigadeUnits array)
I have tried various approaches including the following, assuming that I am addressing the first Brigade in the array:
AllBrigades [0] [2].push (MyUnit);
But when I trace this I just get undefined.
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 RepliesTypes like Movieclip , String, Object act as references when declared and defined, while types like int, Number are primitives. Why such difference has been made. Why not all of them can be primitives ?
View 1 RepliesI'm using the CSS object (TextField.StyleSheet) to format my dynamic text, which is loaded from an XML doc. I tried referencing more than one class, like <span class="body bluetext">. However, it doesn't seem to work because it ignores the first syle(s) and only applies the last one in the list. I'm guessing Flash doesn't support this (since they're CSS support is already very weak). Just want to make sure I'm not doing something wrong.
View 0 RepliesLately I've been twitching in the back of my head wondering just how many references to objects that I'm making, and whether or not they are getting GC'd or not.My question in this sense refers to event listeners and whether or not they are removed in certain cases where you get rid of an object. Two examples:
First, and I think this one is an easy one... when you create an object that adds an event listener to itself INSIDE it's own methods (e.g. this.addEventListener(e:Event, function)), when you REMOVE that object (this), do it's event listeners disappear too? I can only say yes, because they are referencing THAT object and are INSIDE that object.
So I think that question answers itself (but I'd love to know if the truth says otherwise).
But secondly, if you add an event listener to an object from a sibling or parent object, and then remove the object, does that event listener stick around, therefore maintaining a reference to that object and keeping it in memory? And is that the concept that people keep referring to of 'weak' event listeners? E.g. someChildObject.addEventListener(e:Event, function)Also, are event listeners by default strong or weak?
And I am assuming that 'yes', it DOES keep the reference. Which, if you are a n00b programmer like me, you probably are all like, 'aww sh*t damn, how am I supposed to make sure that my objects are getting thrown in the garbage collector's mouth of goodness every once in a while?
I have a files that has movie clips and nested movie clips on the stage. I am now writing a class and want to give the MCs event handlers and other properties.
When I do something like the following: myMC_mc.MyOtherMC_mc.mouseEnabled = false;
I get the error: 1120: Access of undefined property myMC_mc.
I added this to the top of my class and it seems to take away the error, but I thought this was not needed in AS3 anymore.
private var myMC_mc:MovieClip;
private var myMC_mc.MyOtherMC_mc:MovieClip;
What do I have to do to not get the error? How is this done right?
I have this bit of code I am trying to understand how the trace references the buttons.

I've got a 15x3 grid of dynamic text fields in an object called "textbox" that I want to reference through a for loop, so I don't have to have 45 lines of code for assigning stuff to those fields.I have each dynamic field named by their placement in the grid, so, c0a, c0b, c0c, c1a, c1b, c1c, etc.I can also name them c00, c01, c02, if necessary.
I tried:
for (i=0; i<15; i++) {
textbox.c[i]a.text = "Cell " + i + " A";
textbox.c[i]b.text = "Cell " + i + " B";
textbox.c[i]c.text = "Cell " + i + " C";
}
but that gives me a syntax error.I also tried naming them c00, c01, c02, c10, c11, c12, etc., so I could do a double nested loop:
for (i=0; i<15; i++) {
for (n=0; n<3; n++) {
textbox.c[i][n].text = "Cell " + i + n;
}
}
but that gives me a syntax error too.So, is there a way to access all of these with a for loop, or am I going to have to do it the long way?
I have a movie clip in which I have a number of sub movieclips. The number of sub movieclips can vary, so I would like to keep track of them in an array. I am doing that like so:[code]The trace seems fine, showing the names of the correct sub movieclips, but when I try to change the alpha I get this error: TypeError: Error #1009: Cannot access a property or method of a null object reference.
View 3 RepliesI need to update the dynamic text in this flash file I have and export it to SWF. I've looked at the actionscript in all the frames and symbols but the only thing I've found so far are "stop();" 's

How can I see all external file references in flash? I need to be able to tell my boss which files are needed or at least what is missing.

The default value for weakReference in the call to addEventListener() is false. Many memory issues can be resolved by using weakReferences; in fact, some industry experts "strongly recommend always using weak references with listeners".If this is the case, can someone provide me with a good reason why weakReference defaults to true? (Note that I'm not asking why someone would ever want a listener that is not a weakReference, but rather why weakReference=false is the default)

I'm trying to get some things done but run once in a while, well at least, into some issues.Here is one:
I have an swf that is an image viewer/browser that has references on same level, an ImageProperties.xml and some folders full of small jpeg tiles.I actually have a few of these, each in its own folder.Above these folders I have another swf that is the main one, and I am loading from there the other ones with the code pasted at end of this post.
This works if I replace the URLRequest by just the name of the swf to load and I put the main swf with the loader function and the loaded one at same level. But if I leave URLRequest going one level deep "16/xxx.swf" and have the loader swf one level up then it loads the viewer but doesn't show the image.

I'm building a simple Pong-esque game and I've 'hit' a problem. I'm having an issue with referencing one variable from one class into another. Sounds confusing to me, even harder to understand.
Basically I've got this in my "game.as" class:

public function bounceTest (event:Event) {

* 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.
