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 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.
View 3 RepliesI'm getting an error that says Method cannot be used as a constructor - and I can't seem to find what that means exactly.
Here's my code (the line that is getting the error should be in bold):
stop();
var currentAnimation = new mapIdle;
makePlay();

I'm making a kind of image showcase, what has a fluid width and height, depending on browser window dimensions. Everything is okay, I have other kind of issue: in constructor function in this gallery class I can't use stage property, I have to get it from main class. Why Flash treats me this way and how I can avoid this currentStage variable?
Main code:
package dev {
import flash.display.Sprite;
import flash.display.StageScaleMode;
import flash.display.StageAlign;
import flash.display.MovieClip;

Some constructor methods I've seen have the return type :void, even though they can't actually return any values anyway. If it's not required, is there a standard/best practice for that?
View 4 RepliesI just posted a message asking how to call a method from the constructor which has the parameters e: Event. I mistakenly ticked that post as answered when in reality it isnt. I was told I could add = null in the parameter of the function to make it work, like this:

We have a set of FMS's deployed on Amazon's EC2. One of the things we want to be able to do is automatically detect when we should start up another FMS instance. To do that, I've been looking for metrics I could measure on the local FMS box to help me identify "transition" points, e.g., when we should add capacity or remove excess capacity.
I ran some load testing to find out where the capacity limits of a particular box, but ran into a couple of problems[code]...

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.
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?
I was looking at a game engine code and I tried to reproduce myself but I got a compile error.Main.as

On attempting to compile, following error is displayed:

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()
{

what is the difference between something like
package {
public class Myclass {
var txt:TextField = new Textfield();

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){
[code]....
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;
}
}
Having a bit of a problem creating an instance of an object. Bear in mind that this is timeline based and NOT an external class¦

Everything runs fine until the 'new_foo = new foo();' bit, at which point I get the #1007 error.
I've got a function wich can accept a varible number of parameter with a rest operator. I want create an object passing the argument collected with the rest operator directly to a constructor without create an object and call an initializing function and without passing the entire array but the parameters ah I do with apply() function.

here is the scenario we ran across while working on our Flash AS3 project today.
/main/root.fla
/main/root.as
/main/sub1/sub.fla
[code]....
We have many sub swf's that are loaded by the main root swf. The root swf shows the art on the stage of the sub swf, and also runs some code from the sub swf's document class. However, we noticed the constructor was not getting called on the second sub swf if the document class is the same name- even if they are in different folders. Note that we publish our swf files to a separate directory (with the same structure as above) so it is easily copied to the web server.
-root.swf loads sub1/sub.swf
-the constructor of the document class sub.as in subfolder sub1 gets called
-root.swf shows sub1/sub.swf assets with the correctly constructed sub1/sub.as document class
-user chooses to switch to sub2
[code]...
We decided to use a workaround where we basically changed the two document class .as files to be different names (e.g. renamed sub1/sub.as -> sub1/sub1.as and sub2/sub.as -> sub2/sub2.as, and updated the .fla's to point to the renamed document classes), and it works as expected. Hopefully that workaround is useful for someone.I realize most people just name every single file differently and keep everything in one folder, but when you have a sufficiently complicated project, things like this come up.
have a movieclip on the stage, whose Class is "com.nestor.elements.letterKey". The class funcKey extends "key" which contains a "public var val:String". I have many instances of letterKey(asdfghj.... a full keyboard), so I'd like to use the IDE to arrange and pass variables. SO, within the Flash IDE/Library, I rightclick the symbol to access its component definition, and add a parameter for the var in the baseclass name:value,variable:var,default:whatever,type:Str ing).Now, in the constructor function for the baseclass, if I trace my variable: it is null.
View 1 RepliesI'm having a little trouble with my move to as3, (surprise surprise huh?) Basically when I create a movieclip, I wan't to pass some values into it, like so:
