Actionscript 3 :: Catching The Right Event With The Right Listener?

Sep 8, 2010

Consider this scenario we have a class A which is singleton it has a function Sum(a,b) ** . Now we have two classes **Class B and Class C respectively. Both classes (B,C) call add function and listen for a event.

Class A
{
function add(a:int,b:int):void
{

[Code]....

Similarly there is a C and D class. Now when lets say both classes call A's add function (when A is singleton) how does one insure that the right answer is returned to the right listener.

Secondly what if the calls are changing something, is there a locking in singleton?

ActionScript 3.0 :: Custom Event Catching And Listener

Feb 19, 2012

I have an issue catching a custom event that I am firing. I have a view, let's call it "A" which calls a webservice "B", and when that webservice returns with data it fires a custom event "C". "A" is listening for that custom event but never hears it being broadcast. I have trace() lines in each method of the classes and they all fire in turn except the listener.

ActionScript 3.0 ::make A Listener For Catching The CurrentFrameLabel?

Mar 16, 2011

I'm trying to make a listener for catching the currentFrameLabel.

It should listen to changes when entering another framelabel on stage and do this until the page visitor leaves the page.

now i have:

this.addEventListener (Event.ENTER_FRAME, test);
function test (e:Event) {
var lol = MovieClip(root).currentLabel;

[Code]....

this is not gonna work well because it keeps looping over and over, it might slow down the session. And it keeps refreshing the "lol" var.

How can i achieve that the listener keeps working but doesnt constantly refresh the var. Like a sort of pause were it starts again when it detects a change of frame label

ActionScript 3.0 :: Parent Swf Not Catching Child Swf Event?

Nov 18, 2011

I have a child swf that dispatches as custom event:

dispatchEvent(new ModuleUpdateEvent(ModuleUpdateEvent.UPDATE_STRING, topicName));

My parent swf is listening for that event.

{
_laoderInfo = event.target as LoaderInfo;

When I trace/debug out the  _laoderInfo.content it clearly says it is the child swf that was loaded in. however my listner function never fires.

ActionScript 3.0 :: Proper Listener On Tween Event Inside Mouse Event

Feb 23, 2011

My stage has about 25 buttons on it. Each button when pressed to tweens the background to some random x/y coordinates and then loads an external swf file.This is all working, but the timing is off. How can I wait for the initial background tween to end before I make the loader call to the .swf file.Currently each button's behavior is called on the MouseEvent.CLICK event which calls a function that knows its unique filename.swf. I know you can add the MOTION_FINISH even to the tween event but then I would have to call a new function and lose track of the button that initially called it.

ActionScript 3.0 :: Basic Event Listener Mouse Event ROLL OVER

Aug 20, 2009

This is a very basic question but I can't seem to find an answer. I have a mouse over event and have created the buttons with the mouse overs which is working great. I created the actionscript to go to a specific web page when a user clicks the button. Now, I need to add a label to the mouse over so when someone mouse's over any area of the button, it will show them a particular name for the button.

I am sure that this can be done using actionscript in a mouse event roll over command but I can't figure out what I need to show the text. Here is where I am:

Actionscript 3 :: Use The Same Event-listener Callback For Multiple Event Types?

Nov 18, 2011

This might be more of a subjective question, but is it generally best practice to have one dedicated method per event-types that you add an event-listener?

Such as:

myButton.addEventListener(MouseEvent.MOUSE_OVER, onMouseOver);
myButton.addEventListener(MouseEvent.MOUSE_OUT, onMouseOut);
//Somewhere else in the code...

[Code].....

And if you had a MouseEvent.MOUSE_UP, MouseEvent.MOUSE_DOWN and other relevant MouseEvents event-listeners to watch for, you could even set a switch statement to handle all the various MouseEvent types.

ActionScript 3.0 :: Add Event Listener On Parent For Event.target = Child?

Jul 30, 2009

I have these buttons in a movie clip and I would like to have only one event listener for the parent, using event.target to point to the children. I have also tried event.currentTarget, and it didn't work.here is the code that works:

test01.abtn.addEventListener(MouseEvent.ROLL_OVER, mouseHandler);
test01.bbtn.addEventListener(MouseEvent.ROLL_OVER, mouseHandler);
test01.cbtn.addEventListener(MouseEvent.ROLL_OVER, mouseHandler);[code]....

It is only targeting the movie clip, not the buttons inside the movie clip.
