Simplified ItemType Code, contained in Types/ItemType.as
Code:
public class ItemType

public static var SWORD:ItemType = new WeaponType(0, "Sword", null);
public function ItemType(id:uint, name:String, icon:Sprite)

On attempting to compile, following error is displayed:
Code:
[Fault] exception, information=TypeError: Error #1115: Types::WeaponType is not a constructor.
Some of the top level classes can be instantiated as well as called as a function (e.x. new Number() and Number(), new Boolean() and Boolean(), new Array() and Array()).
Usually this is used for type conversion or as a shortcut for instantiation. I would like to be able to do the same thing:

What I wanted to do originally was to create a logging class to interact with Flash/JavaScript, and be cross-browser compatible. I wanted to be able to use the log function as an alias of a method in the log class. This got me to wondering whether I could implement a custom casting function just because. I've now realized it's not possible, but was fun to play with anyway.
I am importing several external files using the Loader-class, and one of them is an swf-file. When doing so (I had done it successfully before, so did not expect any issues), I ran into all sorts of errors, and finally Flash crashed.
I put down a trace in the constructor function, and it didn't trace just once, but kept on tracing, suggesting that the constructor was stuck on loop. I guess the loading of too many of the same swf is what causes flash to eventually crash.
Here is my code (the swf im loading is now a simple test-file which contains an image and no code):
private var slides:Loader = new Loader();
public function DocumentClass()
{

So I usually use an object in the constructor to receive the parameters like new Class({param1:00,param2:0099,etc).To be able to access those parameters from other functions inside the class I create an object, and copy it:
Code:
public class MyClass {
var params = {};
public function MyClass(p){

My air program freezes after running for some time without any error. The app will freeze (non responsive) and the debugger will claim the program has terminated with status 0.
View 1 RepliesI'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?
View 3 RepliesBasic OOP question... I want to add a couple functions to the Array class so that my program will be amazing and make me rich and famous overnight. So I create a new subclass NewArray which extends Array. Do I need to write a constructor method for NewArray? If I leave it blank will it just use the parent's (Array's) constructor method?
View 1 RepliesIf I pass variable(s) like this in document class action script file(I'm not even sure if I can pass more than one variable):
Code:
ballPointRight = new BallPointRight(ball, xDir, padScreen) ;
And now the BallPointRight's action script file:
Code:

doesnt work since it doesnt recognize variables...
Is it possible to store a function constructor in an array? I tried, but getting an error for example, say this is my function:
functiom openPages():void
{
trace("pages open");
}
and my array:
var myArray:Array= new Array(openPages);
I am trying to make a subclass of flash.display.Loader, which should do something when the loader completes loading the content. So I do addEventListener(Event.COMPLETE, onComplete) on my loader subclass. But this Eventlistener is never called. Is this supposed to happen? Can't I use an Eventlistener on the class that dispatches the event? My code looks like this: public class MyLoader
[Code]....
I'm sure that I'm doing something daft here - I just need to remove a child that's created in the constructor through an event listener.My code is below but does not work. Can someone point me in the right direction please?
public class Main extends Sprite public function Main()
super();
var rectangleIndex:uint = this.getChildIndex(playerBackground)

I´d like to know how could use the Timer class extended.I´m trying to pass a parameter to the constructor function, so I can use it inside the listener.
Here´s example:
[CODE]
package { import flash.utils.Timer import flash.display.DisplayObject public class ChangeColorTimer extends Timer { public static const CHANGE_COLOR:String = "changeColor"; public var obj:DisplayObject public function ChangeColorTimer(delay:Number, repeatCount:int, obj:DisplayObject ) { super(delay, repeatCount) this.obj = obj } } }
[/CODE]
That was the ChangeColorTimer that extends Timer.Now, I´d want to know how would I use ChangeColorTimer.I thought it was the same as using Timer.I´ve tried this:
[CODE]
public function changeColor(mc:MovieClip):void { var colorTransform:ColorTransform = new ColorTransform() colorTransform.color = 0xEE0000 mc.transform.colorTransform = colorTransform var changeColorTimer:ChangeColorTimer = new ChangeColorTimer(400, 1, mc) changeColorTimer.addEventListener(ChangeColorTimer.CHANGE_COLOR, setNormalColorListener) changeColorTimer.start() } private function setNormalColorListener(e:Event):void{ trace("called") }
[/CODE]
I called changeColor, but, I don´t get "called" in the output from the setNormalColorListener listener.
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;
}

I have a document class name elevator and my constructor is also elevator as usualHow to call this constructor function within elevator class? Is is possible or not?
View 1 RepliesI have a series values I'm passing (from an FLA) into the constructor of a class. I just want to make clear in my mind that, the only way to pass the variable params, to the function nowDoThis, you'll need a dispatchEvent or a custom event to send it along ?
As an example:
Code:
// constructor
public function MyFunction(_param1:uint, _param2:uint, _param3:uint) {
param1 = _param1;
param2 = _param2;
[Code].....
I have only a vague understanding of using objects and dispatch events. Isn't this something that people need to do all the time?
I'm currently writing a class where I'd like to call the class constructor without having to instantiate the class itself. Something like this : Class:
[Code]...
trace(testString); //wil trace the text "test test123" Is it possible to somehow achieve this? When I write the costructor method like "public static function ClassName" it fails. Is there any other way?
I am new to AS3 and writing classes and keep having a hard time with these error messages I am getting. I have the following AS:
public class PrevNextNav {
public var back_next_nav:MovieClip;
public var next_btn:SimpleButton;
public function PrevNextNav() {
back_next_nav.next_btn.alpha = .3
} .... etc.
The class works fine, except when I try to set the alpha to 30% in the constructor function, I get this error in the output window.
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at _classes::PrevNextNav()
at InteractivePilotDocument()
If I comment that line out, all is good. What does this mean?
I worked out a way to call a function whose name is in a String variable. That is:

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;

How do I call class constructor functions with indefinite number of arguments?
For example:(this piece of code doesnt serve any purpose, just to demonstrate an example)I wish to create a new class Foo with the parameters bar1, bar2, bar3, bar4.

You can declare variables outside of the constructor in a class, so what is the point of a constructor in AS3?
[Code]...
I do know that you cannot call functions, however what is the purpose of the constructor when the code in the class is executed? Why not allow functions and make it simpler?
i have some pretty simple code, i have my document class trying to add a santa class to the stage (simple game ) - but it will not add and i get not errors at all,Santa class:

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.
overloaded constructor method is there in flash? Iam trying the following code but it is giving error like this "A class must have only one constructor."
Code:
function Login(userName:String, userPassword:String) {
this.userName = userName;
this.userPassword = userPassword;

I have encountered a problem when I need to load a third-party flash in to my flash. The flash is written in an erroneous way, it access stage in the main class constructor. I know that a display object can not access to stage property until it is added to stage, and certainly can not access to stage in its main class constructor. I observe 2 cases:
- If the flash run STANDALONE, it run well: I don't know why stage is assign before its constructor
- If the flash is LOADED by my flash, it yield null reference exception as expected
In the second case, if the third-party class remain unchanged, is there a workaround that load flash?
I have to create a game in flash for school. I'm kind of stuck, however. I know an approach that might work, but I'm wondering if there isn't a way to do it all-in-one. Here goes.
I have a start screen with 4 buttons. These buttons all link to different levels, and they all have a different image. Let's call them btn1 btn2, .. btn4. I made a class called 'GameButton':
[Code]...
The other approach I see is to create four different button classes and link each of them to a different button, but then I'd have to create for files for something really simple, which seems like a lot of trouble for well.. just adding a button.
EDIT: I just realised this might be a stupid question. However, isn't there a way to like make a constructor for an empty button, then maybe add a symbol to it?
