ActionScript 3.0 :: What Happens When Event Dispatches Quicker As Eventhandler Can Handle It
Feb 13, 2010
You got an eventlistener for an object that can dispatches events in intervals of 0.2ms.And if the eventhandler would need 0.5ms for his operation, what would happen? (listener and handler are in the same class).Would the last event overwrite the event before? In my case, I get some data from a xmlSocket, and I thought, that some datastrings can come in quicker than to work it off in my handler.

I want to call a function which does something a number of times. The complication is that i want to call it increasingly quickly, ie call it once after 1s, then again after 0.8s, then after 0.5s, then after 0.2s (the actual numbers aren't important I have an equation to work them out).

Why does this code
mySound.addEventListener(Event.ID3, myID3Handler);
cause the myID3Handler to run twice ?!
I also notice that values provided to the handler are not the same, actually the second being the correct one.

My class is dispatching 2 events. One event is captured by another class, and the second event not.I have 2 classes. Class1 creates an object of Class2 and calls a function to load an xml. When xml is loaded class2 dispatches a Complete event. This event is listened by Class1 and then it calls another function of Class2. When the second function executes completely Class2 dispatches second event. Now the problem starts. Class1 is not able to capture this second event. Whereas while dispatchEvent is called from class2, it return true as a notification that the event is dispatched successfully.

Trying to put some event listeners for the "resize" event, evidence suggests that the only object dispatching "resize" event is the stage, right? Moreover, since it is at the top of display list, the event does not travel anywhere else but to the object that registers a listener directly?

I'm running a recursive function which in the worst case senario is of factorial order. (i.e: runs itself n! times)As soon as n exceeds 7 in these worst case senario's the function times out (Error #1502). I want to handle this error event so that the user can be presented with an error that the problem is too complex.I don't want to extend the timeout period as 15 seconds is reasonable.

I am working on integrating the social network "vkontakte" into my desktop application using Adobe AIR. The flow of authorization in the app is as follows:
Open the web browser with a url, and when the user inputs login and password, redirect to somePage.html. From that URL, I need to get an access_token to sign all future API requests.
So the question really is: How can I listen to an event, which will indicate that the user has logged in successfully, or failed to get that access_token?
Here is the code I am using:
package
{
import air.net.URLMonitor;
import flash.display.Sprite;

Does addEventListener(ErrorEvent.ERROR, handler) handle all type of error event, for example, IOErrorEvent.IO_ERROR, SecurityErrorEvent.SECURITY_ERROR, and other all error events? I'm looking for addEventListener() version of try catch(e:Error)(e:Error can catch all type of errors).

I am trying to perform two way binding e.g I have a button (out of many controls), on its selection, I am showing the values of its diff properties(like height, width etc) in some textinput. This one way process works fine.But the reverse process doesn't work. i.e When I select some button, and try to change its dimension by entering some value in height, width textinputs, the dimension are not changed.
private void Form1_Load(object sender, System.EventArgs e)
{
//Create some data and bind it to the grid

I would like the current page to fade out before another html page is loaded into the browser when clicking a link button. So I suppose the event handler needs to call a tween function, get the information when alpha of the main movieclip is 0, and then call the new URL.My wonder is how to make the handler read the alpha value of the main movieclip until it is 0, so that it can act upon it

I'm not sure if it's possible, but can you override a variable of a parent class like you can override a function? I'm trying to create my own event class that can handle the target property. I have a custom imageLoader class, but when it dispatches it's loading complete event:
ActionScript Code: dispatch(new Event("load_complete")); and a listener picks it up, e.target = null where I would like e.target to equal the imageLoader instance that has finished loading.
Does anyone have an answer or a better way to accomplish what I am aiming for?

I have a simple app that stops on frame 1. There's a button that after clicking moves me to frame 2. On frame 2 I have another button to which I would like to add an eventhandler similar to the one for the first button - I am however unable to, as I get the following error :
Error #1009: Cannot access a property or method of a null object reference.
I tried to add the eventhandler after a certain period of time (with the use of a timer) and that works, but seems a totally dumb workaround - and the error obviously pops up because the code that tries to add the eventhandler launches before the second button is actually created. How should I solve such a scenario ? I tried to fiddle with other events like Event.ADDED and Event.ADDED_TO_STAGE but the first one seems sort of wild - it goes off every time I even wave my mouse cursor over the first button (why ?) and the second one doesn't go off at all when my app moves to frame 2 - shouldn't it trigger ?

Is there any way to shorten this code by passing parameters to the eventhandler through the addeventlistener? For example, this is the code:

Basically, just pass the params to the handler through the listener... I hope there is, this is getting tedious...

I have a couple of Sprites on my screen and I want to write a single event handler to handle the double click on any of those Sprites. The following approach works for every event type except DOUBLE_CLICK:
[Code]...
To make it work, because in my application I will have lots of Sprites. In my opinion, a single event and the target property are more efficient than hundreds of event listeners. Am I right or should add event listeners to every Sprite?

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.

I'm creating a scrollbar gallery from a tutorial on this site. Though I've completed the tutorial, and customised the gallery to my own needs, however I'm trying to make a very small change to it - and no matter what I do, keep running into problems. I'm trying to replace the rectangular handle with my own customised handle - a (20 x 20) 'circular' png image that I've imported into Flash, made a graphic and stored in the library (though I understand it can be imported using actionscript, like the other images in the gallery).

I want to know if there is a faster way to take several bitmaps and arrange them one after another in a single layer in a movie clip.
This is how I am doing it currently.
Stage 1: Import the bitmaps to the stage
Stage 2: Distribute the bitmaps to layers
Stage 3: Make the first bitmap a movie clip symbol and cut the other bitmaps' frames
Stage 4: Go into the symbol, create a new layer, and paste the frames.
Stage 5: Click and drag the other frames into one layer, one after the other.
I now have a single movie clip with all my bitmaps ordered one after the other in the timeline.

We've got an app written in Flex that displays data from our app. The .swf file is only 427kb, but it takes a full five seconds to load in Firefox. This is a headache for our users because they need to access the page that contains the app frequently. (The app displays documents, and it's really slow to march through a list of them).
I've confirmed that it's not a slow web server problem. The .swf appears to be cached in the browser. Firebug reports that every time the web page accesses the .swf, the app server returns a "304 Not Modified" response, meaning that the load time from the server is almost zero.
Is there anything we can do to debug this issue? Or is the Flash player just slow?

If you draw a movieclip (with a 3d rotation on it) to bitmap, eventlisteners will always dispatch rollout and rollover for that movieclip (on mouse over). A solution could be to set the matrix3d = null ,draw, and then apply the original matrix3d, but I can't do this in my project 'cause all clips is a 3d object to a parent 3d object that gets drawn to a bitmap every frame.
To see the bug, copy this example code into the first frame on the stage (CS4 flashplayer 10).
var bmp:BitmapData = new BitmapData(100, 100); //setup a dummy bitmap
var bmpContainer:MovieClip = new MovieClip;
bmpContainer.addChild(new Bitmap(bmp));
var box:MovieClip = new MovieClip;
addChild(box);

Are their any tricks or things I can do with actionscript to make images load quicker? I have a full browser xml image gallery and the images are physically big but optimised in Photoshop. I have a preloader to display the loading amount, but is there a way to speed up the loading?Flash image galleries I've seen have images of similar size to mine but seem to load quicker. Is there a way to partly preload the images before they are used. I don't want to preload all the images cos that would take ages.

I've created a small game with Box2d for AS3 - I have sprites attached to the stage that take their position from the underlying Box2d world. These sprites are mostly PNGs.When the game runs with DrawDebugData() bening called every update, it runs nice and smoothly. However when I comment this out, it runs choppily. In both cases all my sprites are being rendered. So it seems that it's running faster when it's drawing the debug data additionaly (i.e. my sprites are on the screen in both cases!)What's going on? Does drawing the debug data flick some sort of 'render quick' switch? If so, what's the switch!? I can't see it in the Box2D code.
function Update(e){
m_world.Step(m_timeStep, m_velocityIterations, m_positionIterations);
// draw debug?[code]...
Interestingly, If i set the debug draw scale to something different to my world scale, it slows down to 19fps. So there's something happening when it draws the boxes under my sprites causing it to run quicker..
