I WIh know how Can I use a singleton class to make only a one instance of a movieclip on the stage.I use this code to make my movieclip instance:
Code:
var mioOggetto:wwp = new wwp();
mioOggetto.y = stage.stageWidth /2 -200;[code].....
I have a ManagerClass with a Singleton implementation inside, I get the instance by calling ManagerClass.getInstance().
Can I get that same instance by just having the class name as a string? I have tried something like:
var theInstance:* = getDefinitionByName("ManagerClass").getInstance as Class;
theInstance.doTrace(); // I get a 1009 error here
My first swf loads a singleton class and instantiate it , and I access to it in the following swf's files (they were loaded in local system).
Now I have to load all swf via http. The issue is when I load second movie throw the first one, I can't get the singleton instance... it seems it lost reference...
I have a singleton class that looks something roughly like this (only with more bindable public properties):
public class Session extends EventDispatcher
{
private var _Id:String;
private static const _instance:Session = new Session( SingletonLock );
private static const SESSID_CHANGED:String = 'SessionIdChanged';
[Code]...
The abnormal behavior I'm discovering is that the event listeners registered through registerOnSessionChange are indeed being called when the session Id changes, but the MXML data binding expression is not updating. I've tried all combinations of dispatching the event during the capture phase, and making it not cancelable, but to no avail. My understanding of [Bindable (event= ...)] is that the MXML should update the url string when the event specified is dispatched, so what am I doing wrong or misunderstanding?
Note: I realize there are lots of different ways of doing the singleton pattern in Actionscript, but unless the way I am doing it is actually causing my problem somehow,
I have a Main class loading 2 SWF (loader and viewer, also with document classes). They need to share a double buffer with content, of course, filled by loader and showed by viewer I was thinking to use the LocalConnection class but after a suggestion from PatrickS now I'm evaluating the possibility of a Singleton Class. I've never used this pattern in AS and must confess I'm rather biased against it.
But in this particular case I guess it'll be useful. By the way, a little bit surprised reading in the gskinner blog 2 implementations examples. So, knowing this subject is an endless war like the Mac vs PC one Take into account:
1. AIR desktop application running 24x7 during some months in a high-end Windows PC. No user interaction
2. High performance code is a must because content loaded are full HD images My other concern is about memory leaks
I'm having a problem where I can't make an instance of a class in one class like I can in other classes all in the same package. When I call the update function from another class it doesn't work. I traced the xPos of the instance of the class I was talking about and I get zero, but that is incorrect so I'm thinking it's the above problem. If anyone knows what the problem is please tell. Here's my code:

I have a few classes in my project which aren't display objects, but they need to know about the stage of my project (stage.stageWidth, stage.stageHeight). Is there a simple way to pass this information along to my classes without using a Singleton or passing these items in as parameters into the constructor??
View 3 RepliesI have a main document class with another class instanciated (mouse follower.as) within it. I want the mouse follower class to access a stage instance. How is this done?
View 1 Repliesaccess one instance of a MovieClip on the stage (blue_mc) from within the class file of another MovieClip (red_mc).e.g. One instance of "Blue" on the stage called "blue_mc", and one instance of "Red" on the stage called "red_mc". Both symbols are linked to class files (Blue.as and Red.as).In Red.as, I set up a function to listen for a mouse down event. When this is triggered, I want to move the instance blue_mc. At the moment, though, I can't seem to get a reference to blue_mc.I've looked into the new stage and root properties, but even though blue_mc is on the stage, it cannot be accessed using stage.getChildByName( "blue_mc" ) either.
Code for Red.as:
Code:
package {
import flash.display.MovieClip;
import flash.events.MouseEvent;

In the Singleton design pattern you can throw a runtime error if the instance has already been created. But this doesn't work when your singleton class extends another class and has to call super() in its constructor, because (for some reason) you cannot call super() if you've already called throw(), or in fact, you cannot compile code that has a potential call to throw() (for example, in an IF statement) that comes BEFORE that call to super().
View 4 Repliesim trying to access Stage Instance in other class but i cant
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at MyClass()
at Main()
I need to know when an element is added to the stage (using main document class). So i use :
Code:
public override function addChild(__child:DisplayObject):DisplayObject{
super.addChild(__child);
trace("child added");
return __child;
}
Which works fine. I also use a static class, to which i pass the stage using :
Code:
public static function setStage(__stage:Stage):void{
_stage = __stage;
}
But if i add to the stage (_stage) a MovieClip from the static class, my "real" stage doesn't seem to get that something was added. So i guess _stage !== stage.
So why is this happening, why is _stage not getting the methods of stage ?
I have a doubt,.... How would you create a Singleton class in Flex...
Is there any convention like the class name should eb Singleton or it should extend any other class.
How many Singleton class can a project have?
Can anyone say the real time usage of a Singleton class?
I am planning to keep my components label texts in a Singleton class... Is it a good approach.
I'm trying to load swf from 127.0.0.1 into my main.swf with Flash Pro
Both swfs have Singlenton class
How to make it that loaded swf use Singlenton of main.swf ?
I did
ActionScript Code:
var lc:LoaderContext = new LoaderContext();
lc.applicationDomain = ApplicationDomain.currentDomain;
myLoader.load( new URLRequest("http/127.0.0.1/loaded.swf"),lc);
anyway I have 2 different Singlenton classes one comes with loaded.swf another in main.swf and variables not shared
is any way I can merge this values?
Is there a way to get an instance reference to the document class to call a method of it from the stage's timeline?I see that here's a possible solution: using a singletonOther solution I though of is using stage.getChildAt( 0 ) but it's not very nice.Is there an 'official' instance reference? because the document class is obviously instantiated at startup, but is that instance accessible in any way without having to use a custom solution like the ones mentioned?

View 3 RepliesI've been searching around all afternoon, and am pulling my hair out. 1) I have a movieclip instance on stage (simple graphical element that represents platforms for a hero to run and jump along). I have placed it on the stage with an external class engine.as and in this class it is called myPlatform and is an object of Platforms.as. The movieClip is called platforms and from a trace(myPlatform.name) the instance name is instance3.
2) I am attempting to access the properties of myPlatform in an Enterframe event loop in my character control and collision class (called hero.as)
Basically here is the bit of code I am trying implement within Hero.as :

This all worked when I was writing actionscipt within the FLA file, on the timeline frame 1. I simply don't know how to access myPlatform from within the external Hero.as class!

Maybe nonsence but is there a way to make some Class instance when owning only its String name?
I mean,
function makeClassInstance(className:String):void{
var instance: Class(className) = new Class(className);
}
That's all about valueObjects. I wish to retrieve classNames from values setted up in main app for universality.
Is it possible to make an instance of a class dynamic at run time? So I can add properties to it?
