ActionScript 3.0 :: Checking If An Event Has Been Dispatched?

Nov 17, 2010

How would I check if an event has already been dispatched or not?

Is it as simple as checking the "target" property if it's null or not? Or are there cases when the target will be null, but it still has already been dispatched?

ActionScript 3.0 :: Event Handling & Architecture Design - Event Dispatched Automatically At The End Of An Animation?

Jan 3, 2010

The app I want to build is an interactive map for a site I'm designing. In a nut shell, students looking to enter an exchange program should be able to use the map-image (as in, an actual 'map of the world') to preview possible destinations (I've attached an image of the two basic states to clarify).

After an introductory animation, I want a mouse-over to trigger a function that populates the map-image with a series of buttons. I need the buttons to be distributed according to information in an XML file (ie. x/y coords, some information text, and an animation to load upon being clicked). I want each button to call a mouse-over function that loads info data from an XML field and place it in a dynamic text field at the top. Then, I want each button, when clicked, to call a function that animates replacing the map-image with an image of the corresponding travel destination. Finally, I want a button on each image that will clear that image from the stage and call the function that populates the map so the process can start again.

I'm working out of a couple of books on AS3, but I'm a little hazy on how I ought to be constructing this thing. So here's the first place I've run aground: After the intro animation, I want the user to mouse-over the stage and have a second animation play (clearing away the introductory text), and I want the conclusion of the clearing animation to immediately call the map-populate function; but I don't want a mouse-over to have any effect until the introductory animation is finished. Is there an event dispatched automatically at the end of an animation? What is the event listener class?

I'm not sure if I should be storing each of these animations in an independent .fla file or if I should create them on all one timeline and have the program redirect to specific frames.

ActionScript 3.0 :: Asynchronous Keyboard Controls - Stop Listening To An Event As Soon As Another Event Has Been Dispatched?

Nov 1, 2009

i have a question to ask about asynchronous key controls This was what i did

[Code]...

and i checked with [URL]...?newspage=6249 and it looked more or less the same, so why is it that when i move my character and when i hold down a key, it just keeps on listerning to that keypress event listener, instead of just executing the other event. So say, i tap left and after which i tap right, it will work just fine, but if i hold left and tap right, the event listerner will still be listening to the left key. So, i was wondering could anyone point me in a direction as to how should i make my code stop listening to an event as soon as another event has been dispatched?

ActionScript 3.0 :: Can Event Listeners Only Be Added To The Class Which Dispatched The Event

Sep 3, 2009

Can event listeners only be added to the class which dispatched the event? I ask because I want to have the logic for the listener on the main class, and the action is dispatched on click from a thumb which is instantiated in a scroller class. Kinda like this:

ActionScript Code:
pseudo code:
class main {
main() {

[code]....

This doesn't work. Why can't the main class listen for an event on the thumb class?

ActionScript 3.0 :: Event.ADDED_TO_STAGE Dispatched Twice?

Aug 19, 2010

I'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:

Flex :: Test That Event Is Dispatched Twice?

Jul 22, 2009

I'm testing some event dispatch code in a Flex app, using FlexUnit's addAsync method for testing that events are dispatched. Great so far, I can ensure that at least one event was fired. However, I want to be a bit more detailed; I want to ensure that exactly the set of events I'm expecting are dispatched. Is there a useful test pattern (or, even, different test framework -- I'm flexible!) to accomplish this?I tried this code, but it doesn't seem to get invoked the second time:[code]

ActionScript 2.0 :: Stop A Dispatched Event?

Feb 24, 2012

Let's say you have a guestbook in where you constantly update the data pulled from a .txt file, but when someone posts a comment and press the SUBMIT button, you'd like that the data is updated at that moment to make it display faster, but since an already dispatched event is coming to update the data of your guestbook WITHOUT the newly posted comment, a flicker might occur, so you would then like to stop that data from being transferred to your Flash file and rather dispatch a new event to load new data with your recently posted comment. Or maybe you just want to know how to stop an event from any class, either way, you've come to the right place.

Let's use that guestbook as our example. Instead of using an onEnterFrame to constantly update the data, I'd use LoadVars' onData event to retrieve the data, but when that data has been transferred, dispatch another onData event, and make this keep going in a loop:

ActionScript Code:
function updateGuestbook(){
loadData = new LoadVars();
loadData.onData = function(data){

[code]...

and then I have this button to submit my comment to the guestbook (keeping it simple):

ActionScript Code:
submit_btn.onRelease = function(){
loadVariablesNum("somefile.php", 0, "POST");
updateGuestbook();
}

so I call the updateGuestbook function, which will fire another event to load new data, but another event has probably already been fired off already with the old data, and this will cause the guestbook to nudge a bit, flicker, if you know what I mean, because first the old data will load, then right after that, a few milliseconds later, the new data will load, and this will be visible to the eye, and will probably not look good.What you can do, is to stop the previous event, delete it, to stop its data from being received by Flash. To do this, simply use this:

ActionScript Code:
delete loadData.onData;

to delete that event, just as simple as that.

ActionScript Code:
submit_btn.onRelease = function(){
loadVariablesNum("somefile.php", 0, "POST");

ActionScript 3.0 :: Event Added To Stage Dispatched Twice

Apr 22, 2011

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

Here is my .fla code :
var section:SectionStructure = new SectionStructure("xml/list.xml")
addChild(section)

The Section Structure code :
[...]
mainHolder = new MovieClip;
mainHolder.addEventListener(Event.ADDED_TO_STAGE, displayObjects);
addChild(mainHolder);
} private function displayObjects(pEvent:Event):void {
mainHolder.addChild(sectionMenu);
}
[Code] .....

The output panel displays "test A" once and "test B" twice. I fixed the problem by adding this little line on the opening of the function createButtons :
menuHolder.removeEventListener(Event.ADDED_TO_STAGE, createButtons);
I read here and there that the event ADDED_TO_STAGE is dispatched when children are added but my problem remains even when I comment everything below this line :
trace("test B");

Actionscript 3 :: Check If UPLOAD_COMPLETE_DATA Event Was Not Dispatched?

Sep 2, 2010

Is there a way how to check if UPLOAD_COMPLETE_DATA event was not dispatched after COMPLETE in Flash?

I'm working on file uploader. It uploads file after file - after COMPLETE next file starts uploading - this is repeated for every file. On last file on COMPLETE if there is no next file allCompleteHandler is dispatched and if some errors occurs it shows that errors at once trough javascript to the user.

I handle that errors in javascript - it stores every error to variable in javascript and after all completed it shows that errors.

ActionScript 3.0 :: Custom Event Not Firing When Dispatched?

Oct 18, 2009

I'm having trouble getting a custom event to fire properly.I have a main class which creates a dynamic textbox (using a custom textfield class (see below)).Another class called book (and extends sprite) , has a method called updateBox() which I want at runtime to update the textbox with some data sent by my custom event which the book class dispatches.The problem is that when the event is dispatched (and I see in the debugger that it does reach the dispatch line) the listener never fires...i.e., the updateText function is never reached, and hence the text box is created and assigned the INIT value but is never updated again..

Here is a scaled down version of my code:

Main Class:

I want to know when the data has been added to a chart so I can use localToData() to draw on the chart. If I do this immediately after setting the dataProvider the chart has not yet updated, so the the call to localToData will not return the correct values. Is there an event I can subscribe to so I know the chart has drawn the data in the dataProvider?

Actionscript 3 :: Unable To Listen For An Event Dispatched From An Embedded Swf?

Aug 2, 2011

I have an as3 class with an embedded swf. I need the embedded swf to dispatch an event and have the as3 class action on that event. This used to work fine when the embedded swf was embedded and had been loaded as an external swf, however now that it's embedded the listener never picks up on the dispatched event.

I've created a simplified example below, the 'onMovieComplete' function is never called.

/* I have an external swf file 'movie.swf' with a simple animation in it.
* When the animation hits a frame (frame 70 in this case) it fires a
* Event.COMPLETE (using:- "this.dispatchEvent(new Event(Event.COMPLETE));" )
*/

why the event dispatched from the embedded swf is never picked up by the listener?

Flex - Debug Which Event Is Dispatched When Double-click The Mouse?

May 13, 2011

I am currently working with a drawing tool for a mapping API, and every time I double-click the mouse a map service will perform a measurement and display the length of the line that I am drawing.

I want to mimic this double-click manually by dispatching a MouseEvent.DOUBLE_CLICK, but the map service is not listening to this default Flex event. I suspect that the API has created a custom MapMouseEvent or something like it that is being dispatched when a user double-clicks the mouse.

Is there a way to determine which event is being dispatched when I double-click the mouse?

ActionScript 3.0 :: Executes In Another Class That's Called From A Dispatched Event Elsewhere Still Run Procedurally?

May 29, 2009

If I change the value of a variable that two different classes can see (in a custom global class, for instance), and then immediately dispatch an event that the other class is listening for, will tracing that variable in the listening class reflect the variable's new value? In other words, does code that executes in another class that's called from a dispatched event elsewhere still run procedurally, or is there some sort of asynchronous thing going on, where the class that dispatched continues on to the next line of code in its own class without regard for what may or may not happen in the other class?

Actionscript 3 :: Handle An Event In A File That Was Dispatched From A Mobile Spark Component

Jan 11, 2012

I have an mxml file called HomeView.mxml in a mobile app built using Flash Builder 4.6. In that HomeView.mxml I have an HSlider, which is dispatching events when the thumb is moved. What I'm trying to do is to listen for that valueCommit event in an .as file elsewhere in the project.

Whenever the thumb moves, an event is dispatched in HomeView.mxml:

hSlider.dispatchEvent(new FlexEvent("valueCommit", true));

I can handle that event in HomeView.mxm, but not in an .as class called view.as

In view.as I import the FlexEvent and I then have, in addedToStageHandler:

stage.addEventListener(FlexEvent.VALUE_COMMIT, commitHandler);

Then there's a simple Handler:

private function commitHandler(e:FlexEvent):void
{
trace("committed!");
}

But this code never runs. I do have a handler in the HomeView.mxml file which handles the event, but for other reasons I need to handle it in view.as as well.

ActionScript 3.0 :: Type Coercion Failed On Custom Event Dispatched Across SWF Files

Feb 20, 2009

Running into a problem dispatching a custom event from a parent SWF made in Flex Builder to a child SWF made in Flash CS4 that is loaded at runtime. Namely, whenever the child SWF is dispatched an event, I get a runtime error:

[Code]....

The custom event is defined in a standalone library that both the flex project and the flash project link to staticly. I wanted to go this route so that as I add new types of events, I can rebuild the application and flash swfs and not have to worry about moving .as files around (lets hold off on RSL's until I get this *simple* case worked out).

This error message makes it sound like the application defines a myCustomEvent at compile time, and the flash movie defines its own myCustomEvent when it is published. Then when the application is run, the myCustomEvent dispatched in the application doesn't match the one in the flash swf. Now I thought that application domains were supposed to sort all of this out, where the child uses the parent's definition for any classes that are duplicated. But when I load the child swf and use the current domain in the LoaderContext I still get the same error.

Actionscript 3 :: Flex 4.5 Not Listening To Custom Event Dispatched In Custom Class?

Nov 4, 2011

I have the following situation:I have an event handler, that displays small messages in my application's statusbar.These messages get passes through by dispatching events from custom components.A simple message could be like "HTTP Error" or so.Now, the main event listener, in the main application file, listens to the event dispatched by any custom component,but seems to refuse listening to events dispatched by custom AS classes.Here is my code for the custom event:

package main.events
{
import flash.events.Event;[code]..

So to sum it all up:

- The event listener listens to the custom event dispatched by any custom component.

- The event listener does not listen to the custom event duspatched by an AS class.

Those who wonder, the event really gets dispatched, that's why I added a trace call.

ActionScript 2.0 :: Eating A Global Listener On The Class And Receive Dispatched Event For Any Instance Of The Class?

May 11, 2006

I've done a class to be able to listen to the event for a CLASS not on an instance.

Code:
class net.webbymx.events.XClassEventListener {[code]....

why did I do this.It cames with my rugby game.I have player in two teams. When a player throw the ball I want the other teammate to act like "wait for ball" and the opponent like "seek for ball". Plus I'm lazy (and I don't want to register the listener for each instance of the player I'm creating). So this class is made to be able to handle as many instance of a class I want without adding a listener on each of them. I'm just creating a global listener on the class and then I will be able to receive dispatched event for any instance of this class .so in my team I can do

Code:
XClassListener.initialize(this);
this.addEventListener("throw", "net.webbymx.game.Player", "wait");

and in my opponent team I can do

Code:
XClassListener.initialize(this);
this.addEventListener("throw", "net.webbymx.game.Player", "seek");
