ActionScript 3.0 :: Object Not Created Upon Calling Constructor
Mar 17, 2009
I am new to AS3 but not to AS2. I have written a simple class and when I import it, I don't see the object that should be created upon calling the constructor. Can you guys tell me where am I going wrong. And I am very puzzled about 'document class'. Yes, I have google numerous threads on "document class" but still very shaky on this matter. Here is my simple class which should place a button object on the stage when I create a new object of this class. Once I have created the BTN class, I have made sure that I have button component in my library, I then instantiate the object by creating a new CS3 file and importing my class:
import com.learning.as3.*;
var b:BTN = new BTN();
When I test the movie, I get the following errors:
1172: Definition com.learning.as3 could not be found.
1046: Type was not found or was not a compile-time constant:
BTN.
1180: Call to a possibly undefined method BTN.

what i am trying to do is by pressing zero_btn which is an object in the library to print a number in the dynamic text box ( result_txt ) which is also an existing object in the library and on stage. my knowledge in actionscript is not much and messing with .as files is totally new to me! then thing is that this code when i locate into to .fla file works fine. there is no error with the code i posted, but am sure something is missing ... like calling the constructor of the .as file.In the library the name of it is Zero_btn and the instance name of this object is zero_btn and it is a button.[code]

If 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)
{
[Code]....
Aside from actually moving the handling of the parameters to the subclass or shifting it off to a separate initializer method

is it possible to get the name of a calling function or the constructor from the called function? is it possible to determine the previous function of the thread?
i would like to call some setter functions from my constructor and have my setter functions determine if it was the constructor that called them.
currently, i'm setting a boolean for this functionality, but perhaps there is another way?
public function Constructor(myNumber:Number)
{
this.myNumber = myNumber;
}

How to create new class instance without calling constructor function, meanwhile constructor function must exist and is requiring 1 parameter.
var newclass:myclass = new myclass; <- still calls function myclass in myclass class
I would like to call constructor function later:
newclass.newclass(myparam);

Is it possible to create an instance of a class without triggering the class' constructor?[code]In the case above, say I wanted to play around with a Foo instance, but I really don't want my global.foobarCount going up, nor do i want to pass in any value at all for bar.This could be useful for introspection where you want to learn more about or pass a particular class object but don't want to provide required arguments or trigger anything that the constructor may do.Is this at all possible? (Obviously, new Foo() just doesn't cut it here, since it would throw and arguments error, nor does just using Foo, since that's a reference to the class itself).

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. So that after each button is clicked, it updates some text in my document class. My event listeners for the buttons are in the buttonTemplate class. My question is, how do you call a function in the document class from a constructor class? Here is my simplified code below
DOCUMENT CLASS
Code:
package {
import flash.display.MovieClip;
import flash.text.TextField;

this is my first post on this forum so please take it easy on me as I am sure that this will be a simple answer for most of you out there. Here is what I am working with: I have dynamically added 4 buttons to the stage using XML data and a loop to place as many buttons as will allow per the data. Once the game begins, a MovieClip that I have also added to the stage will jump randomly from frames 1-16 and stop using a stage event listener. I need to have event-listeners on each of the buttons I have created using the XML data to check to see if the user has selected a correct answer. I had intended on using a function that would check to see which button was clicked and check to see what frame the movieClip was on when that button was clicked and judge right or wrong that way.

I've always just developed my projects in as3 instead of mxml and I usually just setup my application to run a main actionscript file as my main doc root, sort of like how you do it in flash but in flash builder I do something like this:[code] how can I call place a call to that function hitme() within the call_from_outside() function between the <fx:Script> tags?The reason why I'm doing this is because I have some flash swfs that I load into another swf file and I can access the top level public functions of those flash swfs, however the top level of the flash builder/flex swfs is the main mxml file not my fake as3 class root. Of course I should think there is a way for me to access the as3 class methods of the mxml component but for keeping things with the same structure, I can bypass having to modify my loader scripts.

Im having a problem where I have a set of numbered functions and I need to call them from the dynamically created buttons but I need to make sure the numbered functions are relative to each button..so button 1 will call function 1.

var1 = "blablabla"
var2 = "blablabla"

Is it OK to use the constructor to set properties for a value object class or must I use dot notation and set each one, one-by-one? I recently read an article that was saying I should do it one-by-one as value objects should only contain properties and went on to say using the constructor is not OK (best-practice wise).
Code:

I have the Class and the parameters of its contructor as an object. What I need to do is a function that returns an instance of this class, passing this parameters to the constructor.
This is the code:
Some random and unmodifiable class:
public Foo {
public function Foo(a:int, b:String) {
// constructor
}
}
And some function (in some another class):
function bar(params:Object):* {
var baz:Foo = new Foo(params.a, params.b);
return baz;
}
What I need to do is make this function generic, without pass params as parameter to Foo constructor because I can't modify it. Something like:
function bar2(clazz:Class, params:Object):* {
var baz:* = new clazz(/*some magic way to transform params in comma separated parameters*/);
return baz;
}

I am working on a side-scrolling platformer game. Because of this, I have a class that acts as a floor. I also have a class representing enemies. I am having problems with passing a parameter to a custom class' constructor. The class (SkullDemon.as) extends MovieClip. I am trying to pass an instance (called "floorL1") of a customer class called "FloorLevel1." "FloorLevel1" also extends MovieClip (I do not have a written .as file for "FloorLevel1"; I just exported the floor MovieClip to that class).
I am trying to pass an instance of "FloorLevel1" so that the "SkullDemon" object can land on the floor just like in a platformer. My main class is called "TME2_Main." This is the class from which I try to pass the "floorL1" instance to the "SkullDemon" class. This is how I try to create a Skull Demon instance and pass "floorL1" to its constructor:
[Code]...
What am I doing wrong here? I have spent a while looking for solutions (including moving code outside of TME2_Main's constructor),

I have a class in my .fla's library called StatBar_object. StatBar_object is an inherited class that extends from a custom class StatBar, while StatBar extends from MovieClip.
However, StatBar's constructor has a parameter (the constructor reads "public function StatBar(target:int)"). Thus, I continually get an output of:
"ArgumentError: Error #1063: Argument count mismatch on StatBar_object(). Expected 0, got 1.
at actionscript.stat::StatBox_object()
at actionscript.modes::battle_mode()"
Is there any way to get StatBar_object's constructor to include StatBar's parameter?

I want to serialize ThugtrisShapes' children (heritage/polymorphism) but his children like Right_LShape take constructor parameters,i have to assign it a default value (in my case null because they receive an Array type), but i get this error even when implementing IExternalizable.
Take Note: IForm extends IExternalizable.
here is a link i found about it but it still does not work...[URL]
Code:
public class ThugtrisShapes extends Sprite implements IForm

var squares_:Array;
var numsquares_:int=MAX_SQUARES;

I know that not all class' can be cloned , but cloning is an important aspect of OO programming.... There should be a solution for my problem,besides taking the parameter out of the constructor and add a setter.

I have the component Hadlab Newsflash on my stage.I have a button that, on rollover, changes the color of the component.When the button is clicked, the component fades out (tweenning) and the movie goes on. The problem is that the constructor keeps telling the component to be #FF0000(red) and the fade out tweenning doesnt work anymore because the mouse is on the button. Here is the code:
Code:
// cria a funcao "onRollOver" para o btnEnter
btnEnter.onRollOver = function() {

I'm trying to dynamically addChild a Sprite to an already tweened MovieClip (tweened on the Flash timeline).
Let's say ObjectA is the tweened object, I published it in my swc and linked it to my Actionscript project in Flash Builder. I make an instance of ObjectA in my class, and then try to do the following:
var objectA:ObjectA = new ObjectA();
var objectB:ObjectB = new ObjectB();
objectA.addChild(objectB);
addChild(objectA);
Now, the problem is, objectB doesn't tween along with objectA. Is there any logical solution to this?

Steps - Make 2 MovieClips. One MC will be a 500x400 picture. The other MC, will be a simple circle called "Ball". Make that Ball a Class by editing the properties, and assigning it the Class name "Ball" as well.1) Picture is static, so we have the picture MC sitting on Frame 1.2) Within the Document Class file, instantiate the new "Ball" class with name "ball" 2a) I want the "Ball" to be added to the picture class, so that every time I call it, the Ball is inside the picture. If you were to trace it - trace (picture.ball);Anyone know how to go about doing this? The code for simply instantiating the "Ball" class = Code:var ball = new Ball(); addChild(ball);

I am using the reflect class at [URL]. It works fine for the first playthrough. Yet, when the movie loops again, it creates another instance and again on the next loop through. There is only one object on the page and the script is: import com.pixelfumes.reflect.*;var r1:Reflect = new Reflect({mc:box, alpha:50, ratio:50, distance:2, updateTime:0, reflectionDropoff:1});

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),

is the STAND_LIST[0] keeps created every new instance of Stand created? or is it created just once?if it's created every new instance of Stand created, how do i make it run just once?(like initializing const)
