I've got a class which attempts to call a method upon Event.ADDED_TO_STAGE firing. Instances of this class are obviously added to my stage (I can see them) yet my onAddedToStage method never gets called.
HTML Code:
package
{
import flash.display.MovieClip;
import flash.events.Event;
[Code].....
I can't get the event to run, what's wrong?
ActionScript Code:
package classes{
import flash.display.*;
import flash.events.*;
import flash.net.*;
import flash.text.*;

How does the ADDED_TO_STAGE work? I have a class but it doesn`t work outside the document class. How do i create a new instance of the class i have? It throws me an Error #1009...
this is the class... it works if i put it in the document class field...
Code:
package {
import flash.events.*;
import flash.display.*;

I've got a strange issue: an ADDED_TO_STAGE event listener executes twice..should I pay attention to some particular thing?
View 2 RepliesI'm getting this weird glitch where the added_to_stage event seems to be dispatched twice when I construct my object.Now I know that my constructor is not being called twice cause I traced a string before the event listener, and it only traces once but I traced the same string within the listener handling function body and it traced twice.
Here's the code:
Code:
package com.berubegraphics.martinemartell
{
import flash.display.MovieClip;
import flash.display.Sprite;
[code]....
I would like to listener ADDED_TO_STAGE Event, this event will run more than one, and first run time same object is null.How to fix this error?

I have this slight problem with the event ADDED_TO_STAGE. The listener is launched twice so I figured the event is dispatched twice.

I'm attempting to initiate a set of variables within a movie clip myElement as soon as it's dynamically loaded onto the stage:
frame1 within myElement:
PHP Code:
this.addEventListener(Event.ADDED_TO_STAGE, initiateVars); function initiateVars(ev:Event):void{ var currentY:int = this.y; var currentX:int = this.x; }
I'm trying to make this happen only once, and only when myElement is first placed on stage, but the code above doesn't work. Am I misusing the ADDED_TO_STAGE event?
despite using ADDED_ON_STAGE it is throwing TypeError: Error #1009: Cannot access a property or method of a null object reference Below is my code of main class and menuScreen class.
MAIN CLASS
ActionScript Code:
public class main extends MovieClip[code].....
I made the following discovery while attempting to use the ADDED_TO_STAGE event with timeline code. I don't know whether to say it's a real problem, or maybe it's just an observation, but it's very simple to demonstrate. Just make a MovieClip symbol in the library, and set it for export. On frame 1 of this MovieClip symbol, enter this code:
ActionScript Code:
import flash.events.Event;
addEventListener(Event.ADDED_TO_STAGE, added);[code]....
(Note: I called my MovieClip symbol Screen1, and gave it a class name of Screen1 when I set it for export. But I am letting Flash create the class for me, there is no same-named class in the classpath)Next, put this code on frame 1 of the main timeline:
ActionScript Code:
var screen1:Screen1 = new Screen1();
addChild(screen1);
Looking at that latter code, apparently when the screen1 instance is created in line 1, the object hasn't fully finished instantiating before line 2 is executed,because the trace message never happens.Prior to this, I had assumed that code on frame 1 of a MovieClip, if it were "base level" and not inside any functions, was roughly equivalent to the constructor of a class. Apparently that isn't so, because whenever I add an event listener for ADDED_TO_STAGE in the constructor of a class, it always works, even if the object is immediately added to the display list, exactly as above.
In some of my other testing, if the movie clip instance is later removed from the stage and added again, the added and removed handlers fire just fine. It's only this initial time that it gets skipped. Also, if you add an event listener for ADDED_TO_STAGE from the main timeline instead, like this:
ActionScript Code:
screen1.addEventListener(Event.ADDED_TO_STAGE, added);
It works just fine.The conclusion I draw from all this is that there is no way to use the ADDED_TO_STAGE handler inside a MovieClip's frame code and have it fire the first time. Also that there may be no real equivalent to a constructor when you let Flash create the class for you. Thoughts, anyone? I am attaching a FLA file (CS4 format) in case anyone might want to examine this without putting a file together yourself. Don't expect anything at all fancy, though, it's nothing more than what I described above, and I fully expect you'll want to delete it later.
I have an error code #1009 and have been googling around and found a lot of links, yet I'm not sure where to put the Event.ADDED_TO_STAGE to make my project work. The error code is

I'm using flash cs3. I'm trying to to add the eventlistener on a movie clip timeline (frane 1) that is in the library. If the code is in the timeline then the event is never registered when flash adds it to the stage. If however I put the code into an external class (doing the linkage stuff) it works fine.

well i have a problem to which there are lots of related searches over the net but none could solve it. well the problem is that i have an XML driven carousel menu that needs to be loaded using the preloader. After the load is complete i can find my swf menu's backgound and the static buttons getting loaded but the buttons that should load in the carousel using xml are not present.
I have come across the even ADDED_TO_STAGE to load the swf once it has completed its dynamic loading. But they have used it in the documentation class for thier project. I am not using any separate actionscript file.All my code is written in the 1st frame of my project .... I really need a solution to this problem
I've built a UIComponent in AS3. When I drag it onto the stage during authoring time, the ADDED_TO_STAGE event fires.
I have an event handler, but it's really only meant to perform actions at runtime, not when I'm dropping the component onto the stage to design the layout. Is there any way to check to see if the component is "running" in a live SWF?
Basically, I don't want the ADDED_TO_STAGE event handler to do anything at design time.
here's the code.
var zipTimer:Timer = new Timer(1000, zipArray.length-1);
zipTimer.addEventListener(TimerEvent.TIMER, onTick);
zipTimer.addEventListener(TimerEvent.TIMER_COMPLETE, onTimerComplete);
[code]....
Now, I can't see, for the life of me, why this isn't firing. It's almost exactly the code from Adobe's docs...zipArray.length is at least 32.
I'm working on a scene where the user can drag sugar, honey and syrup flavour to a cup of coffee and each time they collide, the coffee's happiness is increased by 1. I added a TweenLite so that sending any of the objects to their original positions is much more fluid. The problem is that the hitTestObject is now firing more than once (which makes sense and now happiness is increasing at more than one increment at a time) but how can I make it so happiness is increased just once?
Code:
public function hitsDecaf(e:Event):void{
if (myCounter.myHoney.hitTestObject(myCounter.decafSweetened)){
ifStartTimer = true;
stopDrag();
myCounter.steamHappy.gotoAndPlay(2);

I have the following:A document class, extending from a custom class, extending from MovieClip. In my document class, I assign a handler to the FullScreenEvent like so:
Code:
addEventListener(FullScreenEvent.FULL_SCREEN, function(e) { toggle_fullscreen(); });
Also, I've set up a SimpleButton to call that same function, toggle_fullscreen, when clicked.Here's the catch:When I click the button, my app goes fullscreen. When I press Esc, the app goes back to normal but the FullScreenEvent doesn't get fired,so I can't catch it to re-align the elements on my stage.I've also tried to add the event listener to the stage object of my document class, but that doesn't work either.
The problem is that I've done a lot of work in my game, and there's too much code bound to shift and control keys. For example you need to hold shift key to select multiple soldiers or control key to shoot or sometimes pause the game or even call a map, a lot of stuff in GUI depends on those keys as well. Both KEY_UP and KEY_DOWN are added to the stage object. But, time after time, there happens a very annoying thing, KEY_UP event just doesn't fire for shift or control (in most cases it does, but not always). That is, I press shift, start selecting soldiers, then release shift but Flash Player keeps thinking it's still pressed, so I can still select multiple soldiers, which is not good.
I found the exact same problem here: [URL]
I have some code where an event handler listening to Event.ID3 fires twice for an MP3 file. From searching the web, I found a few others asking a similar question, but I haven't seen any response.
Does anybody know what would cause the ID3 Event to fire twice for a single file? My only guess is that the MP3 file contains two versions of ID3 format.
The code looks like this:
Code:
var mySound:Sound;
function setup()
{

I am having a problem with my ProgressEvent.PROGRESS handler. It looks like this:
Code:
function handleProgress( event:ProgressEvent ):void {
var percent:Number = Math.round( event.bytesLoaded / event.bytesTotal * 100 );
trace("Uploading %" + percent);
}
It just traces "Uploading %100" every time
I am using a big file so I know its taking several seconds between calling URLLoader.load and complete. There just doesn't seem to be a report in between 0-100..
I keep running into problems where I want to add an event listener onto a class instance RIGHT after it's instantiated, like this:
Code:
storiesXML = new XML(XMLdata);
storyBook = new vStories(XML(storiesXML.stories));
storyBook.addEventListener("storyBookLoaded", storyBookLoaded);
. . .
But by the time we arrive at the third line, the "storyBookLoaded" event has very often (inconsistent) already been dispatched from my class instance:
Code:
var evt:Event = new Event("storyBookLoaded", true, false);
dispatchEvent( evt );
...
(Even though quite a lot has happened in the class before that.) To be clear, I don't want to add storyBook as a display child, and even if I did, the addChild() method would have to be called after instantiation of storyBook, so we'd have the same problem. I know I could set a timer in the vStories class to artificially delay the dispatching of the event, but that seems really hack-ish, and would have a real compounding problem if I have to do it too often as everything builds up. How to make sure custom communication events happen after their listeners are set?
I have a little flash app that I have running constantly on my server (I made it an exe). It runs great for a few days, but then eventually it just stops.
Code:
trace("test1");
var myTimer:Timer = new Timer(5000, 1);
myTimer.addEventListener(TimerEvent.TIMER, getData,false,0,true);
[Code].....
The code above should call the function getData once after 5 seconds have passed. This works 99.99% of the time, but for some reason (usually after a few days of it running) it doesn't call the getData function.
I have verified this through trace statements. When it eventually fails, it traces out test1, test2..... then nothing else. No test3.
I'm assuming I need to add an event listener for the timer object to check if it fails for whatever reason. How do I do this?
Can anyone see why my event.Complete isn't firing

I'm sure some users on this forum will be aware that AddThis are dropping the Clearspring Launchpad, so I'm writing a new API to get ready for the changeover. Part of that is a base UI that will create buttons for social network sharing destinations. At the moment, AddThis contain all the icons in a single long strip that is 16x3520 pixels in size [URL]...
What I'm trying to do is load this into a utility class, but the Event.COMPLETE event never fires, and if the Loader class that loads it is added to the stage, the bitmap is never shown. I thought it was maybe a dimensions issue, but what is curious is that if I place the PNG on a Flash stage and export as a SWF, it loads no problem. If I dump it out as a JPEG, no problem. Its ONLY when the file is a PNG that there are problems trying to load it. I even tried dropping it out as a 24-bit PNG (the original is 8) but that had no effect.
I am simply trying to link a button on my site to another webpage (an online store). The site is currently live at Higdon Florist (won't let me put the dot com address due to forum rules) The last 2 menu options (View Bouquets and Place Order) should link to (store dot higdon florist)
On PC, this works just fine every time.
However, I have reports that Mac users have trouble. The action never fires on the first 4 or 5 tries. Then, suddenly, it begins to work (and continues to work thereafter).
My AS3:
import flash.net.URLRequest;
import flash.net.navigateToURL;

In my Flash project I have a movieclip that has 2 keyframes. Both frames contain 1 movieclip each.
frame 1 - Landing
frame 2 - Game
The flow of the application is simple:
User arrives on landing page (frame 1) User clicks "start game" button User is brought to the game page (frame 2) When the game is over, the user can press a "play again" button which brings them back to step 1
Both Landing and Game movieclips are linked to separate classes that define event listeners. The problem is that when I end up back at step 1 after playing the game, the Game event listeners fire twice for their respective event. And if I go through the process a third time, the event listeners fire three times for every event. This keeps happening, so if I loop through the application flow 7 times, the event listeners fire seven times. I don't understand why this is happening because on frame 1, the Game movieclip (and I would assume its related class instance) does not exist - but I'm clearly missing something here.
I've run into this problem in other projects too, and tried fixing it by first checking if the event listeners existed and only defining them if they didn't, but I ended up with unexpected results that didn't really solve the problem.
I'm new to ActionScript development and am using the FlashDevelop IDE. I've been playing around with some really simplistic things and have come across a problem I can't seem to solve.My application compiles and runs, and a function that watches click events fires perfectly and I can see the event in the console when I pass it to trace(), yet the same code watching for KeyboardEvent fails to fire at all.Here's my code:
package GameTesting
{
import flash.display.Bitmap;[code]............
The MouseEvent trace() fires every time as expected, but KeyboardEvent never fires, no matter what key I press.
I'm writing a SWF that I'd like to communicate with a Java process via Sockets. This is usually quite easy with standard Sockets, but for some reason the events described in the Socket documentation aren't firing when all signs say they should be.
On the Java side, I've set up a ServerSocket that's listening on port 8080. Using netcat I've confirmed it works as designed.[code]...
When I run the resulting SWF, all I get is "Called connect!" on the stage, and none of the events ever fire. Even more strangely, when I investigate the communication from the ServerSocket on the Java end, it receives and accepts a connection. When I close the SWF the code calling my Server completes as normal -- meaning it was hanging on a connection made with my SWF.
I'm left with a few questions...
With the exception of the event handlers, this is the end of control for my code (after the connection is established, we just wait for events and render them appropriately). Could the entire program be "terminating," and I'm just misunderstood about the Runtime model?Are there visibilty/naming requirements for the callbacks for them to be called? They're all public, but could it be that the Runtime isn't seeing them?Are there any gotchas with AS3 Socket programming? I kept thinking this was an issue of sandboxing, etc., but the SECURITY_ERROR didn't fire either.
