In Flex, is it possible to listen to all event types of an object that's an IEventDispatcher? addEventListener's first parameter is the type, which is a string. In many cases the documentation is not clear what event type it fires. I'd like to attach a generic listener to inspect the events.
View 2 RepliesWhat I want to do is to dispatch the click event when the component is clicked. (The class is essentially some text in a textfield that needs to be able to do certain things, and it needs to be able to respond to a click). Sounds easy enough... I want the event dispatched when that portion of the text is clicked. But uh...how? it's not like a button where I can just go myButton.addEventListener(MouseEvent.CLICK, myClickHandler);That's clear, because some component is going to be listening for the Click event dispatched when myButton is clicked. It is built into the AS3 framework that a button knows how to listen for a click event.
After the import statements I've got:[Event(name="click" type="mx.events.Event")]How do I dispatch the event when the component is clicked, when the component doesn't yet know how to respond to a click event? I've tried adding an event listener in the textfield which contains this custom class of text, but nothing's happening because the Click event hasn't been dispatched.
i came across this problem and i have no clue why it's happening. basically, consider 2 nested movieclips on the stage, something like stage -> main -> filler. both movieclips have instance names (main and filler).

this throws an error 1119: Access of possibly undefined property filler through a reference with static type A. can anyone give me a hint on that, as it works with class A, but not B extending A? i understand it was meant to work?
I have an swfLoader that loads a flex swf. When the flex swf is loaded it takes up the entire stage, this does not happen with a swf of the same dimensions created in flash professional.

I am making a fighting game in Flash and while I have everything running, I am missing something: a victory/loss screen.Logically,I know how to do it:
if character.hp < 0
{
character.dead = true;
dispatchevent("death", event)
}
My problem is that I have no idea as to how to code it. I know I will use two classes and my two .fla files (unless I am wrong).I have two .fla files that are in play here: the Menu.fla file and the Arena.fla file. Menu.fla contains the entire navigation of the game, options, character selection screens, etc. and when it is time for the player to engage in battle, it loads the Arena.fla file, which contains only the backgrounds (depending on the selected stage) and for now is set to a length of one frame only. For Arena.fla, the real action happens in my classes, but logically, I would only need HP.as and Character.as.
In Character.as, I have declared the following variable:
var isDead:Boolean = false; //is character dead?
In HP.as, believe I should have the following:
if(currentHp<0)
{
currentHp = 0;
character.isDead = true; //declared as var `character:Object;`
EventDispatcher.dispatchEventListener("playerDead", playerDead);
}
And finally, in Arena.fla, I want to be able to detect the above-mentioned eventlistener and simply move on to a second frame which will display a message in the style of "PLAYER ONE HAS WON" or "PLAYER ONE HAS LOST" with a button that will allow me to go back to the character selection screen. This is the first part in which I am stuck: how do I detect the dispatched event listener in my main .fla file?
Secondly, if the player clicks on the "CONTINUE" button, which displays regardless if the player has won or lost, how can my Menu.fla (which loads the Arena.swf) detect this click event, unload the game, and go back to the character selection screen?
I have several classes with some eventListeners in my project that interfer with each other. I.e. i have a mouseclick event that is not triggered, when i have another class with init events running at the same time. when i remove that other class, the mouseclick event is triggered correctly.
now i am not 100% sure, but i think the solution to this has something to do with EventDispatcher.can anybody please tell me if that is correct and how i can add EventDispatcher to my code without recoding everything?
For some while I am researching on dispatching Events on AS2 which can bubble as it happens in AS3. This is not the first time in this world and I hope you all know how to do it in AS2. My issue is not on addEventListener but the removeEventListener which is not removing that particular event from that object.Cause the handler argument in the mx.events.EventDispatcher is throwing undefined where that should be [type Function]. At the time of registering on addEventListener it is registering the handler as [type Function], but it throw undefined on removeEventListener method.

Considering the above code if for example I want to broadcast the event of onLoad of xml to different listeners objects with the scope of movieClip in which the xml object is declared, so that later mcs from the library can be attached dynamically.However this approach does not seem to work.
Theory question, more than anything.
Code:
var page = _root["pageinstance"+num]; //num is a variable,
page_li:Object = new Object(); // page_listener object
page_li.onPageLoad = function() {
trace("hey, look, the page loaded");
page.display();

The code is much more complex than this, but thats the skeleton of it. Anyone, my question to you is that I need to use this over and over again, for each time the user presses a button. My problem is that Flash seems to have trouble when I try visiting a page I've already been to, because the events don't properly execute. I've tried page.removeEventListener(); and delete page_li; but both seem to be ineffective. Basically, how can I whip the slate completely clean, so that the next time when Flash goes over this code, it executes properly?

i have a class called "RandomErrorClass" that extends Error:
Code:
public class RandomErrorClass extends Error {
public function RandomErrorClass() {
super("random error...");[code]....
my understanding is that the second class, the one that throws the error, will have to extend the EventDispatcher class. is that right? but it already has to extend the MovieClip class. my questions: Does the movieClip class already inherit from the EventDispatcher class? if so, i won't have to implement the IEventDispatcher interface, will I?
I'll try to explain my problem as simple as possible So, I have class A (main class) and class B, and I need these to communicate with each other.

This gives me the error: Access of undefined property RNDMCOLOR... but, I made it public, so it should be accessible by other classes right? Apparently, no I have also tried to type the string "rndmColor" directly into the eventDispatcher and listener, and that gets rid of the error, but the chooseColor function is never called. So what the heck am I doing wrong? How do I make variables accessible from other classes if public doesn't do it?

View 1 RepliesI need to send a signal from my class BasicVideo.as, to my main class Main.as.
BasicVideo.as extends (and needs to extend) Sprite.
So, how can I dispatch an event from that class to the main class without extending EventDispatcher?
I'm reading Jesse Marangon's EventDispatcher tutorial. Most of it makes sense. However, when I copy the code into Flash I get a return of objEvent. count = undefined.It looks like the external class Interval is being properly found/used as the rest of the function works.
View 2 RepliesIs there any way to list all listeners to an EventDispatcher instance, or at least list all event strings that are being listened for?
I know there is a "hasEventListener()" function, but you need to know the string you pass in in order to check for it. I suppose it would be bad coding ethic, but it can have its uses. (Am I making myself clear enough on what I am looking for?)
Also, how are eventListeners speedwise? Since there is a lot that needs to be accomplished when dispatching and listening for events, would it be a bad idea to use an Event system for such potentially CPU heavy items as collision detecting?
I have a sprite A which has a child, sprite B.Sprite B has a variable, instance of class C which only extends EventDispatcherIn class C, I dispatch a custom Event. The eventlistener in sprite B reacts on the event.The same eventlistener in class A doesn't respond.If I dispatch the same custom event in the eventhandler in class / sprite B, this event is seen in class / sprite A.Is there a difference in events going through the displaylist and those who are from an EventDispatcher?
View 6 RepliesI want to override the dispatchEvent method while inheriting from flash.display.Sprite. Whenever an event gets dispatched now like ADDED_TO_STAGE and CLICK it will get through dispatchEvent in my theory. However there is no single trace he'll get through dispatchEvent.. so the events get dispatched internally from some where else?
