I'm having a problem using superclass constructor with arguments. I've searched all over for the solution and found some really useful advice. Problem is i;ve followed it and it doesn't work... not for me anyway. So i've learned that you need to callthe super constructor in the subclass' constructor to avoid this error. problem is, this code still gets the same error....

I always don't call super() when I extends Sprite.But doesn't not calling super() cause any problem?Till now, I don't have any problem and I have never seen code which call super() in constructor which class extends Sprite. How about TextField? I don't have any problem about TextField, too. How to know whether I should call super() or not?
View 3 RepliesIs it possible to call a method in the super class of a super class? I tried the above and it doesn't work, unsurprisingly. Only way I've been able to do it is to store a reference to a super.someMethod in the super Class (eg. var superMethod: Function = super.someMethod) and call that instead. Seems reasonable and it works but wonder if there is an in-built method for doing this?
View 6 RepliesIf a constructor takes its parameters as a vararg (...) it seems to be impossible to create a subclass that will just pass on that vararg to the superclass.
There is a related question with fix for this same situation for normal functions: Wrapping a Vararg Method in ActionScipt but I cannot get that to work with a super call.
base class:
public class Bla
{
public function Bla(...rest)
{

Aside from actually moving the handling of the parameters to the subclass or shifting it off to a separate initializer method
I got something just like that:

I dont know if that is normal, but this code create an infinite loop, because when i create a new instance of class Two, because of the extends, the class One constructor is called again, and creating a new instance of class Two, and so on...I know how can i get this fixed, but, what i want to know is, this is correct? Its a Flash bug? Isnt that way in AS3?
I have a library object (SomethingMC) which extends a custom class (Something). Something, in turn, extends MovieClip.If adding SomethingMC to the stage within Flash CS3 IDE, is it possible for it's super class (Something) to assign an instance name from a class constant (Something.THE_CONSTANT)?
package
{
import flash.display.MovieClip;[code].....
The above does not work. It throws Error #2078: The name property of a Timeline-placed object cannot be modified. if the instance is assigned a name in the IDE, and it just doesn't work if no name is assigned in the IDE.
I have a class. I can call the constructor (initialize the class), and the constructor can then call a function/method inside it's own class (so I know it works), but when I try to call the same function/method myself from the instance of the class I just initialized, I get an error.

To work, I need to uncomment this constructor, or I get that error (1203:...)Why Base classes on AS3 doesnt directly inherity parent constructor? Why I must have to redefine it?
Following on from an answer I gave here: AS 3 | Cloning Png image data
I knew that to get a transparent BitmapData Object it was necessary to specify a background color of black, but until I was called out on it I never bothered to check why. Having checked, I wonder if there is a reason I don't see for what seems like conflicting default arguments to the BitmapData constructor? First, here is the constructor as defined in the documentation:
public function BitmapData(width:int, height:int, transparent:Boolean = true, fillColor:uint = 0xFFFFFFFF)
the default value for transparency is true.Now consider what the docs say about the transparent parameter:
transparent:Boolean (default = true) — Specifies whether the bitmap image supports per-pixel transparency. The default value is true (transparent). To create a fully transparent bitmap, set the value of the transparent parameter to true and the value of the fillColor parameter to 0x00000000 (or to 0). Setting the transparent property to false can result in minor improvements in rendering performance.
It seems to say that this parameter is useless unless you set the fill color to black. So why then is the default fillColor value 0xFFFFFFFF?If a developer wants the performance gain of no alpha channel, it must be explicitly specified:
var bmd:BitmapData = new BitmapData(width,height,false);
And if a transparent BitmapData is required, that too must be explicitly specified:
var bmd:BitmapData = new BitmapData(width,height,true,0x000000);
So at no point can we rely on the shortest constructor form, without accepting a performance hit, and I can't understand why.Surely either the fillColor should default to black:
var bmd:BitmapData = new BitmapData(width,height); // transparent BitmapData
or transparency should default to false:
var bmd:BitmapData = new BitmapData(width,height); // faster, no-alpha BitmapData
already searched for this kind of thread here but didn't get any answer that suited me.
It comes like this, I made this class (LoadWebPage)to basically remove the old Swf and load a new one. I've associated this class to my menu Btn's.

I am trying to extend the new AutoComplete component from Adobe. In two different places I need to bypass the AutoComplete methods and get right at the ComboBox methods.
I was told that super.super.someMethod() works just like it does in Java. But I keep getting Compiler errors:1084: Syntax error: expecting identifier before super.Any suggestions other than just cutting and pasting the code and extending the AutoComplete superClass?
For Example:
package{
public class A {
var test:String;
public function A()
}} class B{
}
The code is in the same file, we call B is inner class, then how to call the constructor of class B
In the AS3 there is a remark, that a Class Constructor is just a method of the class, that is executed when an object of that class is created. So, since the constructor is just a method of a class, how can I call it directly from the other class methods?
View 8 RepliesThis is my first post. I'm new to actionscript, but not to programming. I hope to learn a lot from these forums. To the point: I decided a few days ago that I wanted to create a flash game. I'm taking an object-oriented approach to the game design since that is what I know. The issue I am having is that I have a class called Hero that inherits from a class called Entity. Now my issue is that I don't want Hero to call the Entities class constructor when I initialize a new Entity.

I'm attempting to call a Class constructor dynamically using factories:
ActionScript Code:
public function construct(classRef:Class, initArgs:Array):* {
var factory:ClassFactory = new ClassFactory(classRef);
var classInstance:* = factory.newInstance();
return classInstance;
}
This works just fine, except when the constructor of the classRef being passed in requires arguments, as in the sample class below:
ActionScript Code:
public class Foo
{
public function Foo(arg:String) {
[code]....
Is there any way I can call construct(Foo, "Hello World") and have it properly pass the parameters to Foo's constructor? (I'm not locked in ClassFactory, by the way, I also tried classRef.apply(initArgs) and a few other hacks to no avail.)
I've got a simple program that consist of a document class and a buttonTemplate constructor class. I need to call a function called updateText that should be in the document class, when someone clicks on a button. My event listeners for the buttons are in the buttonTemplate class.

I have an image gallery with thumbnails and a previous button and next button. "nextPrevPosition:Number" starts out with the value of 0 and increases or decreases by 1 every-time the previous or next buttons are pressed. The thumbnails assign a value when those are pressed:

all works fine except when NextPrevPosition reaches the original value 0...and this is when I get the error message. It looks like the line "currentPort = new(POSITION[nextPrevPosition] as Class)(); is when it is happening.
