I have created a class:

And then I create a new instance of the class:
Code:
var scroller:Scroller = new Scroller(_contactDisplayPage.getChildByName("contactInfoHolder"));
And I'm getting an error 1136:Incorrect number of arguments. Expected 0...
I have a bunch of sprites in my library which all behave in the same way.

I'm having trouble with the constructor for a custom Class tied to a library MovieClip.
Say I have a MovieClip in my library named Circle, which is tied to the class com.shapes.Circle . I want the Circle class contstructor to take 2 arguments, xScale and yScale:
public function Circle(xScale:Number, yScale:Number) { }
However, if I try to call that from in code, for example Circle ball = new Circle(3.14,2.0); , I always get an "Incorrect number of arguments. Expected 0" error.
Is it possible to have a custom class tied to a MovieClip that can take arguments, or does Flash not allow this? I'd asked about this before and thought I figured it out, but from looking at it now I apparently hadn't figured it out and had resorted to a sloppy workaround; I'm hoping to fix it now.
For example, I have the class Bullet, with a constructor: Bullet(start:Point, target:Point)constructor
But, if this Bullet class extends the MovieClip class, how do I pass start and target into it? Right now I am using attachMovie to create instances of the class. (They behave correctly with the static properties set by the constructor, but to be useful it needs arguments.)
I have a class with constructor and overloaded methods in it. When i try to import that class using blazeds i get an error saying [RPC Fault faultString="Unable to create a new instance of type 'some class'." faultCode="Server.ResourceUnavailable" faultDetail="Types cannot be instantiated without a public, no arguments constructor."] How to import class having overloaded methods using blazeds
View 1 RepliesIs it posible to have predefined arguments in a constructor so if the user doesn't enter one it takes the default value? I tried doing it this way:

I'm having a weird behaviour with some some classes that I'm making. It seems that the Boolean values from arguments get changed on the way. I have two classes. On is called Carousel and the other Activity. The Carousel main task is to instantiate several Activity objects and place them in a way that resembles a carousel. This part is done, but there's a problem passing arguments from Carousel to Activity. Some data to instantiate the Activity come from an XML file. The XML resembles something like this:

I'm making a game in action script 3. In it, I have an actor class from which player and enemy classes will be derived. I'm doing this so that unless I need to provide specific AI or fancy behavior (such as for bosses), I can just make a new clip in the library for each enemy without making an actionscript file.
However, I've run into a problem.
Whenever I try to pass arguments to the construction of an enemy (make it spawn with more health), I get error 1136 (Incorrect number of arguments.)
This is because the constructor created automatically at runtime doesn't have the same arguments as it's parent class. Is there any way to get around this without making a class file where I copy and paste the parent constructor function for each of my hundreds of enemies?
I'm passing a DisplayObject to a command that will instantiate it. Something like this:
// ViewClass is passed into this method typed as a Class
var view : DisplayObject = new ViewClass() as DisplayObject;
Is there a way to pass arguments to ViewClass() without knowing it's type? I'm assuming the list of parameters passed to any object's constructor is an array, but I'm not certain how to proceed.
I know I can do something like this:
// Assume arguments, an Array of arguments, has also been passed in
var view : DisplayObject = new ViewClass(arguments[0], arguments[1], arguments[2], arguments[3], arguments[4]) as DisplayObject;
But clearly I'd like something more dynamic, like to be able to just pass the arguments Array directly. I suppose all of this, however, goes against any type safe checking
I've drawn a pretty button in Flash and given it the Class name PausePlayButton. It extends PlayerController, which allows it to toggle on and off and control whether a MovieClip is playing or not.When I instantiate it, I want to pass a reference to the MovieClip it controls into the contructor so that PlayerController has access to the MovieClip's public methods. However, I can't pass a reference into the constructor of PlayerController, unless I can pass it into the constructor of the symbol itself and call super. But where is that constructor? How do I give the button a reference to another object?
View 1 RepliesI know what instance variables, contractor methods, local variables and constructor arguments are (I think) but I'm confused as to when or how to use them, for instance I have use this a lot and I don't really understand why it is used like this...
[AS] package standard.testing {
import flash.display.MovieClip;
import flash.events.Event;
import com.greensock.*;
[code]....
Why create a function with arguments...
[AS]public function tweenMe(mc:MovieClip, xPos:Number, yPos:Number)[/AS]
Then create instance variables...
[AS]
public var _mc = MovieClip;
public var _xPos= Number;
public var _yPos = Number
[/AS]
then create local variables with the values of the arguments
[AS]
_mc = mc;
_yPos = yPos;
_xPos = xPos;[/AS]
Is it possible to pass constructor arguments to instance objects which I place on the stage? Are the instantiations of instance objects centralized somewhere as with .NET WinForms so I can just edit the xxx = new CustomRecangle() constructor?
public class CustomRectangle extends MovieClip {
public function CustomRectangle(width:int, height:int) {
this.width = width;
this.height = height;
}
}
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]

I am creating a Weapon class for a game and the weapons itself will be the sub classes. The sub classes will hard code some values (such as max ammo and the weapon name).
I trying to access this declared data in the base class constructor, at the moment it's not outputting the values. Is this possible?
I've broken my Weapon class for simplicity:
ActionScript Code:
package
{
import flash.display.MovieClip;

My current workaround is creating a protected method in the base class to trace the information and calling that method in the sub class's constructor, this works fine but this doesn't seem like the most efficient technique?

I'm really new to actionscript so I'm not even sure how to ask this. First off I'm not using any Adobe IDE just notepad with flex as a compiler. What I want to know is how to make a class but make it with arguments and then have that class use those arguments.
The only way I can clarify what I mean is through an example. So for example say I have my main class and a class called square. Now I think (and i could be wrong) I can 'make' a square class in the main class by simply saying new square(); in some function of the main class. But lets say I want this square class to have a x and y value. Would I establish this by saying new square(x,y); in the main class (where x and y are integer values)? If not how so? Also how would I get the square class to read these values? How would I go about getting the square class to draw a square with its center at the x,y given to it in the main class?
I'm building a small website. It's external class based and the ideia is to load the menus and content externally, by XML.
I'm using as base code an example from "Learning Actionscript 3.0 Book", from Rich Shupe and Zevan Rosser.

The problem happens in line 21 and line 27. The error is the following[code]...

I have a movie clip there. I put a trace in the constructor of the class of that movie clip but it will not show the trace comment in the output window-its not working. There are no errors.
I also tried instantiating the same movie clip from the document class-which worked-but the trace in it's class's constructor still does not output.
I have a document class called Main that is defined for my main movie. In the library of that movie there is a MovieClip called HomeBlock for which I have written a custom class called HomeBlock that defines its behavior. This HomeBlock class accepts one parameter in the constructor right now, an XMLDocument, and the Main class sends it to HomeBlock in the constructor call like this [code]...

I'm making a class called 'player', and really, I don't need a constructor function for it. Do you just outline the function, but don't put anything between the curly braces? Also, I'm a bit new with access levels. If I wanted my functions from my player class to be accessible from the main class, do I make them public?

I'm doing something - probably very stupid - with an external library swf. That swf so far contains two buttons each with their own classes 'Simple_Button' and 'Simple_Pop_Button'. In the library swf document class I set up an object that lists the available classes:
Code:
oClasses = {"Simple_Button":"com.Home.Button.Simple_Button",
"Simple_Pop_Button":"com.Home.Button.Simple_Pop_Button"};
In the swf that loads the library swf I process that object and create another object with proper class references based on it:
Code:
function initHandler(event:Event):void {
defineLibraryClasses(event.target.content.getClasses(), event.target.loader);
addBtns();

I have a custom class, MyMC. The only argument the constructor takes is a string, which sets the text of a label inside MyMC.
In the Flash IDE I've placed an instance of MyMC, which is called mcOnStage, on the stage. Through the document's class Main I'd want to perform the constructor function of mcOnStage.
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?
