ActionScript 3.0 :: Constructor Argument For Instance Already On Stage
Mar 4, 2010
I have a Sprite in my library that is linked to a class (lets call it SomeClass), and i put on stage in Flash, and name the instance someClass. In my Main.as i then write:
var myClass:SomeClass = this.someClass;
SomeClass.as has a constructor with the same name as the class, however it require an argument. How do I pass that to the class when I made an instance of it directly in Flash by dragging it to the stage? (instead of the usual ... = new SomeClass(arg); )
I tried something like this:
myClass.SomeClass(arg);
But that gives me this error:
1061: Call to a possibly undefined method SomeClass through a reference with static type SomeClass.

let's say I have a class:
public class SomeClass{
var name:String;
public function SomeClass(n){
name = n;
}
}
If I do var s:SomeClass = SomeClass("test");, it tries to convert a string to SomeClass. How do I prevent it from doing that?

I'm trying to pass my object class as constructor argument. I have something like this:
package myclass {
import flash.display.MovieClip;
import flash.display.BitmapData;
import flash.display.Bitmap;
[code]....
Now, when I try to create my Example:
import myclass.Example;
var example:Example = new Example(myObjClass);
I get message, that I'm not passing any variable (Error #1063). Why is that? What is wrong with it?

is good practice to use if(source==null) in my costructor, to run code only if the costructor argument is provided ?

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.

function test(myI,myX):void {
myI.x = myX;
}
lets say i have an instance name BigWindow so i use test(BigWindow, 100); but it doesnt work,
function test(myX):void {
for(var i = 0,i < 10,i++) {
BigWindow + i.x = myX;
}
}
and i have an instances named from BigWindow1 to BigWindow10.so i use test(100);it doesnt work too.what's the correct way of doing this two?

Well I want to set up a function that will calculate the x position of where my MovieClip's instance name will go. Here is the code i currently have.
function xBtnPosition(btnName: String, btnXpercentage: Number):String
{
var xFinalPosition: String = -(((btnName.width * btnXpercentage) / btnName.scaleY));

is it possible to obtain the instance name of a class from the class without having to manually pass the instance name as a string parameter to the class constructor?

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 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]

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'm having a problem with customized Actionscript objects not recognizing thier own constructor. This is the pertinant part of my script:
ActionScript Code:
//File: Line.as
class Line extends Object{
public function Line(args){
[Code].....
Clearly, the variable "testLine", is one of my custom "Line" objects. Clearly, it has been made with the "Line" constructor. So why won't flash acknowledge this?

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 know I can create instances from a string like this:
var classFromClassPath:Class = getDefinitionByName(classPath) as Class;
var instance:Object = new classFromClassPath()
I know I can call some function with a parameter array like this
var x:Function = someFunction;
x.apply(null,args);
But does anyone know if I can pass parameters like that when I construct a class?

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.MovieClip;

For a project i am needed to move a vast range of movieclips over time on the stage.I thought to write a class to tackle it. my little class experience tells me you can't acces the stage in the constructor. well great, just add an eventlistener for the ADDED_TO_STAGE. I wonder how to pass the stage.stageWidth to a custom class as an optional parameter.[code]

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've read a lot of different articles and discussions about the null object reference that occurs when a loaded swf tries to access the stage before it has been added to the display list.
And I'm wondering, "Is there seriously no way to handle this issue without modifying the SWF being loaded?" Even with Flex or otherwise?

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;
}
}

my movie is linked to an external class called game, and in the game cosntructor I am trying to access instances on my stage. I have tried MovieClip(root).instancename, root.instancename and even tried adding an event listener to listen when the movie is done loading because I thought maybe it was because the instances on the stage weren't created before the constructor is ran. This is the main class, shouldn't it be easy?
