ActionScript 3.0 :: Listen To A Custom Event In Various Classes At Same?
Jul 17, 2011
I'm using a electronic device to dispatch events within AS3.
short explanation: -->
Think of these events as a KeyboardEvent.My point is to dispatch an Event (like a Key that is being pressed) so I can listen to this event on EVERY Class I need to.I'm not sure how to instantiate or listen to these events correctly =/
I mean: I want to be able to listen to the key that is been pressed as if that was a global event every Class can receive...
long explanation: --> I'm doing something like this:
1) created a (main) Class that extends a Sprite.
2) created a class (KeyboardInput) that extends the main class.
3) created a class (KeyMap) that extends EventDispatcher.
4) created a class (HomeScreen) that extends a Sprite.
My FLA file is associated to the KeyboardInput Class.This Class creates a listener for the KEY_DOWN KeyboardEvent and instantiate the KeyMap Class that dispatches a CustomEvent:
stage.addEventListener(KeyboardEvent.KEY_DOWN,function(evt:KeyboardEve nt):void { keymap = new KeyMap(); keymap.setKey(String.fromCharCode(e.charCode)) });[code].....
I'm new to flash and programming in general but am learning it to make games. I'm currently messing around with hit detection and its not to hard to test in the game tick ( fired from onEnterFrame). What I'm wondering is if it would be possible / useful to create a custom event that i can listen for. And make the eventListener hear when a collision happens. Also would this be better or worse for the cpu than testing the collisions of lots of enemies on a screen?
I'm having the following problem: I've implemented a custom headRenderer for my DataGridColumn. The idea is to have a dropdown menu when clicked on the column header. The problem is I don't know how to add a listener or pass a variable to the renderer since the renderer class is instantiated by the ClassFactory.
I have a repeater component with custom event. My repeater components fires custom event holding data. My need is to dispatch event so other repeater components can access data from dispatching component.
I have movieclip which contains child movieclip. when child movie clip finish to play i want to run a function in a parent movieclip. so I made a custom event dispatcher in the first frame of the child movieclip:
I am learning how to do a custom event in AS3. I can do an event in a class but I dont know how to detect events in other classes. I want to detect in main.as an event reached in class player. E.g., a variable reached a value 4 in class payer and dispatches an event so main.as can detect it. This doesn't give an error but my code doesnt output I can deect an event in main from classplayer.
I finally got the variable referencing between classes and custom event problems sorted out. Now I got a question regarding the Error #2044 and Error #2035. The error reads like this:
Error #2044: Unhandled IOErrorEvent:. text=Error #2035: URL Not Found.
I've put all the swf in the same directory, so I don't think that is the problem. Could it be that my XML file is in another directory that's causing the problem? I also heard having quotes in the URL in the XML file could also be problematic. Is that true? Here are my AS and my XML file. [code]......
I have 2 custom components, which have their own nesting hierarchy ... One is container for another. I have to "familiarize them" with each other. The way I'm trying to achieve that is using global events (one side is firing and the other one is catching):
Application.application.addEventListener("Hello", function (data:Event):void{ // .. some actions });
[Code]...
Then should be created the connection between container and it's child.
BUT, the only thing I could acheive is passing a reference to the Container in the DynamicEvent. Is there any chance that I could access the child at the event-handler function.
I'm still struggling with the complete concept of custom event handling within AS3. I know I am close to a complete understanding it's just not falling into place yet.[code]...
You have some examples of how works custom events in as2? If I have 2 classes that extends movie clip, how can I make them to comunicate with custom event.?
I've created a base class to house some basic functions I'd like to have across several movie clips in a game I'm making, however, when I link a custom class to the same movie clip I get the message; "The base class will not be used because the class specified is already defined and extends its own subclass. If you wish to use the base class, specify a class name in the Class field that will be auto-generated or enter the default base class 'flash.display.MovieClip' in the Base Class field." I removed the 'extends MovieClip' inside the Class but it still shows the message. Does this mean that I cannot use a custom class and a custom base class on a movie clip?
I am trying to learn JavaScript and I am wondering whether JavaScript has a event listener just like ActionScript's ENTER_FRAME. Basically, I want this event listener to listen "all the time" not just wait for any particular instance (mouse click, keyboard event) of event.
I know the difference between the two, but I never felt the need to use the bubbling feature. If I want to listen to an event from a deeply nested children, I always use the capture phase. Could someone explain to me why I should rather use bubbling, its advantages, and maybe show me a situation in which bubbling would be the only solution?
This is NOT duplicate of my earlier post (its is slightly different)But this is similar issue with similar error but its not the same error The error I am getting now is below while dispatching the custom event from my custom component
TypeError: Error #1034: Type Coercion failed: cannot convert events::MapEvent@a74ab51 to flash.events.MouseEvent. dispatchEvent(new MapEvent(MapEvent.CLICKED_ON_MAP));
Note: The error in my earlier post is giving below error message
Type Coercion failed: cannot convert flash.events::Event@81ecb79 to com.events.ShopEvent
The difference here are two things, the earlier error is while converting flash event to custom event and now this one is while converting custom event to flash event and secondly, I have no clue why it is trying to convert to the mouseevent where I am just dispatching my custom event with proper listeners.
I came to some misunderstanding how to use events. LOL. I thought I understand it but as I see I dont.
I've got a Engine document class where Hero is added, and Cannon object too. In body of Hero I need to dispatch event when Hero reaches some point or particularly a pitfall, so I've got static const string to handle it:
[Code]...
but this way I would end up with dozens of handlers in the Engine body class, and I am trying to minimize this class as it is big enough without those handlers. I am stunned and suprised, and I am noob again. Maybe someone will clear out how to get custom events working/... and why only instance of object that dispatches an Event can hear it (my case).
I am trying to wait for and Event.COMPLETE in another class but my code just jumps through the event listener and executes the following code without waiting for the event to complete so my variable is not being set.[code]
I have two buttons that listeners for the same event that have identical instance names?For example, I have two buttons which have the same instance name: imageOne.Can those identical buttons listen for the same event? I tried, but only one button responds to the event listener .why do I need two buttons with the same instance name that listens for the same event?because I have a looping scrolling panel of thumbnails, and when you have scrolling panels, we all have duplicate panels inside for looping purposes...so since I have to have two identical panels grouped together to do the loop, I have multiple buttons with the same instance name.and these buttons listen for events...now of course I can rename the other half of the identical buttons with different instance nams, but a problem arises when i want to use an if statement to check to see if that image is already loaded.for example, say I image1 is already loaded, and someone clicks identical thumbnail that has a different instance name, ti would be too complex to write an if statemen to determine whats loaded.
I know there's been quite a few posts about events, but I've run into a problem that I haven't really encountered before, and I've kind of confused myself with all the talk of "bubbles" and "capture" and various complexities of creating custom events, etc...Anyway, I'm trying to figure out how to dispatch a global broadcast style of event.1) If I have a custom class that resides in the Display List (the DispatcherClass), how do I set up this class to broadcast a "global" event?Actionscript Code:1b) If I have another custom class that also resides in the Display List (but in a completely unrelated heirarchy), how do I get this ListenerClass to "hear" the event WITHOUT explicitly referencing the instance of the DispatcherClass like so:
Actionscript Code:DispatcherClassInstance.addEventListener("DispatcherClassEvent", handler, false, 0, true);Is this even possible?2) What if the DispatcherClass DOES NOT reside in the DisplayList?Is it possible to dispatch a "global" style event since there is nothing to "bubble" up through?2b) How would I get a ListenerClass, maybe on the DisplayList, maybe not, to "hear" this event?
I am trying to create a text effect using a custom class. The class receives refferences to the TextFields that I want to apply the effect to, an the effect should take place whenever the text is changed in these TextFields. The problem is that Flash doesn`t seem to provide a way of listening for the TextField.text event of a Dynamic TextField... Or does it? Just to clarify: On the stage I have a dynamic TextField named tText. I create a new instance of my class and call MyClass.addTarget = tText, which is supposed to tell my text effect class that it should apply the effect to tText, whenever the .text property changes.
PS: What I have tryied was TextEvent.TEXT_INPUT, but apparently that`s for Input TextFields, whenever the user inputs some text. I change my text through code. I have also tryied Event.CHANGE, but that doesn`t seem to work either...
I've got 3 classes: The class that recognizes the change in URL (using SWFAddress by Asual):
[Code]...
And the "Hello World" never appeared in the output window - so I'm not sure if is it possible that my MenuPanel has a chance to receive a info about completing the validation triggered by some other class?
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.

Im having the issue of functions firing too soon after each other and need to use listeners. But using what I thought was correct below is not working.ThexmlData.addEventListener(Event.COMPLETE, initialize); should call the initialize function in this example, right?
