Is there any difference in performance, or instantiation speed, between the two? Will anything be different in the instantiation of the MyClass object?
public class MyClass
{
private var _myObject:SomeClass = new SomeClass();

I like finding out about tricky new ways to do things. Let's say you've got a class with a property that gets set to the value of an argument in the constructor, like so:[code]That's not exactly a hassle. But imagine you've got... I don't know, five properties. Ten properties, maybe. Rather then writing out each individual assignment, line by line, isn't there a way to loop through the constructor's arguments and set the value of each corresponding property on the new instance accordingly? I don't think that the ...rest or arguments objects will work, since they only keep an enumerated list of the arguments, not the argument names - I'm thinking something like this would be better:[code]
View 2 RepliesIn my library I have a movieclip that is linked to my AS3 custom class TweenButton. On the movieclip there is a textfield. I would like to be able to set the .text property of the textfield through TweenButton's constructor, which must be so simple, but I haven't been able to make it work. Here's the code and source files:

I know the topic of "duplicating" movieclips is a hot issue with the new virtual machine. Luckily, I understand the implications. I only am [currently] interested in duplicating a Bitmap. See, I load an image from an URL using 'flash.display.Loader.load', which is a non-blocking operation in Flash Player.However,I may use multiple copies of the loaded image (which is reported to be a Bitmap, naturally) in the display list at the same time.Hence, I naturally do not want to load the image from an URL every time, because I don't want to wait for a non-blocking call to complete. Nor do I need to - I mean one copy is already loaded, so it should be possible to just "duplicate" it, right?
My idea is to do use the bitmapData property of a Bitmap and pass it to the constructor of a new Bitmap object. I have not tried the following in action, but I want to hear whether any of you did and if the following would not work, what would:
Code:
var original_bitmap: Bitmap;
var copy_of_original_bitmap: Bitmap = new Bitmap(original_bitmap.bitmapData);
LiveDocs mention that the BitmapData being passed to a Bitmap constructor is "being referenced", which to me might suggest it cannot be used twice? There is also the BitmapData::clone() method, which I am not sure is applicable here or not.I know this is a lot of talk instead of just trying this out, but I test so much Flash Player code daily just to see "what works" (which should be documented instead by Adobe),
I'm trying to migrate a Flex 4 project backwards to Flex 3, and I need to move stuff mapped in a <fx:Declarations> block in MXML. Does Flex 3 have something similar to this? It's been a while since I've done Flex 3.
View 4 RepliesThe "Programming Adobe ActionScript 3.0" states in chapter 4 "ActionScript Language and Syntax", "Packages and Namespaces", "Creating Packages" that you can declare at the top level of a package multiple variables, functions, and namespaces in addition to a single class as long as only one is declared "public".However, in Flash when I declare a public class and any other variable or function either with the "internal" attribute or no attribute, I get this error:5006: An ActionScript file can not have more than one externally visible definition: test.function1, test.Test

I would like to iterate through an object's validators. Validators must be declared in a declarations tag. How does one scroll through declarations? If one cannot, is there a better of locating all validators other than scrolling through all properties of an object?

Is it possible to access a declared component as an IFactory within an MXML class? I've used this style of declaring factories many times for Skin Parts, but I've never figured out how to access those factories from within the MXML.

I have two Gallery classes (in two separate folders) that extend GalleryMaster (which resides in the folder above them). How do I specify this in the import ... declaration?Are the import declarations paths relative to the swf that you load?
View 4 RepliesWhile coding, I wondered if a plugin exists that I could highlight a series of variable declarations, hit some special keyboard shortcut and BAM! They would appear in alphabetical order.Is there anything that does this in Flash Builder? Or FlashDevelop even?So it would go from this:

private var _helloWorld:String;
private var _foobar:Boolean;
To this:
private var _foobar:Boolean;
private var _helloWorld:String;

We used to write our UnitTests with FlexUnit and we were just testing our model. Now we want to test the view too. Before i run my tests i create an instance of my view and my model to test the stuff. When i try to access the view i get a null pointer exception. If i add the view to the displaylist it somehow works - even if i remove it from the list right after adding.it looks something like this:
var myView: MyView = new myView();
//myView.initialize(); will throw error

I'm looking to load external .swfs that have graphical assets in them which are all 'exported for actionscript', and instantiate those assets in a .swf packaged for iOS. I'm using the adt command line packager to create the .ipa file. I'm including the .swf files while packaging. The .swf files seem to load correctly, and give me no errors, but when the Loader for each .swf's bytesLoaded equals bytesTotal the content property remains null.The program works perfectly when I package the .ipa using the -target ipa-test-interpreter flag, but not when I use the -target ipa-test.
I'm assuming the problem is that iOS doesn't allow Flex developers to load external .swf files that contain actionscript, and the 'export for actionscript' in the external .swf files counts as actionscript for the purposes of Apple's security policies. I'm looking for confirmation as to whether or not this is the problem.When using adt to package .ipa files, does iOS block external .swf files that have library assets that have been 'exported for actionscript'?

How do you instantiate an MC that resides in an external swf library?
So for instance loading "shape.swf" and instantiating "square_mc" from it's library onto the parent stage.
i've been struggling with one problem for weeks, and i've just found what i think is a possible cause (or at least a contributing factor)
This line:
Code:
var totalOffset:Point = rangedWeaponData.totalOffset;
What i thought it was doing is creating a copy of a static variable, for me to manipulate. However my debugging seems to show so far that it's actually creating a reference, and my subsequent manipulation of that is also manipulating the base variable it references.
Code:
var totalOffset:Point = new Point(rangedWeaponData.totalOffset);

I asked yesterday how to call a function from an XML file, and I figured out how to make that work using the string-to-function call.so in my XML file I have <ITEM CALLBACK="ContactsList">View All</ITEM>, and my TextMenu class parses the XML file and creates my navigatable text menu instance. When enterMenu():String is called, it looks to see if the CALLBACK attribute has a value, and if so it returns it as a String.so..

I am loading one swf into another using the Loader class, but when the child swf finishes loading and is added to the display list, its Document Class is not instantiated. I have a few trace statements that should execute when the object is created, but nothing is happening when loaded into the parent SWF. When I compile the child SWF on its own, the Document Class runs as expected.
So I'm wondering... how do I associate a child SWF's Document Class with Loader.content?

Is there a way I can load a swf file but not automatically instantiate it's DocumentClass? Instead I want to do something like the following:
protected function mainLoaded(e:Event = null):void {
trace('mainLoaded');
var main:* = this.mainLoad.createClassByName('Main');
trace(main);
}
Where mainLoad is an instance of CasaLib's SwfLoad and createClassByName is the equivalent to
loaderInfo.applicationDomain.getDefinition();
The thing is that when my swf finishes loading I can see it is created, because of some trace calls, although its obviously not added to the display list.
Here is the code:

private class someFunction(classRef:Class):void

Can I perform the check without instantiating?

You can right click and see the source.
1.) How can I instantiate the bricks without taking such a big performance hit?
a.) currently, I�m instantiate the bricks that make a column one at a time. I tried doing this with a repeater which did work but I could not get the animation to work on each individual brick. The animation would only work across the entire column.
2.) How can I get the UIComponent that contains the brick columns to align itself to the vertical bottom 10 pixels above the box along the bottom with the slider?
a.) I'm currently adding a UIComponent to the stage dynamically and then keeping a reference to that UIComponenet, I am adding my bricks.
3.) How can I improve the animation?
a.) Most of my research has suggested the only way to animate a sprite is to use a Timer() or connect to the onEnterFrame event.
I quickly realized that instantiating all movieclips in the document class all at once is probably not a good idea. I want to call movieclips from the DisplayList, instantiate them when needed. How do I go about on doing that.
