Is it common knowledge that distributing an event to 1000000 listeners is twice as slow as manually calling these listener functions for each such listener in 1000000 loop? This is what my conclusion is, I just cooked up some code benchmarking this. How is the native API useful then (aside from in retrospect when it probably will get more effective), if anyone can replicate it using non-native code, that will be a couple of kilobytes worth of extra code, and one can potentially achieve much greater speeds.
I know the flash engine is single threaded so when it receives an event, does it essentially break off, execute any registered event listeners (in no guaranteed order) then return to the current scope?[code]can I guarantee that the current function will complete before any of the event listeners execute? ie trace("Done"); will ALWAYS execute first.
I have made an event listener:text0_mc.addEventListener(MouseEvent.CLICK, showMe);showMe is a function, but I need it to call more than 1 function at once i.e. -ext0_mc.addEventListener(MouseEvent.CLICK, showMe1, showMe2, showMe3, showMe4, showMe5, showMe6, showMe7);Each function contains an if statment as below.
function showMe1(event:MouseEvent):void { if (shuffledArray[1]==orderArray[1]){
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 two document classes. The main document class creates a empty movieClip and adds it to the stage in which the second document classes published swf is loaded into. The second document class has a button component on the stage in which once clicked just traces 'hello' to the output window.
What I want to do is upon clicking this button a Event is dispatched from the second document class, to the main document class. Now, I've Googled everything in this known world and have tried to implement examples to no avail. I'm really at a loss right now yet I stubbornly intend to keep banging my head against the problem. Below I have pasted both document classes minus the examples I've tried to implement thus far.
I´m making a game.This game has 4 frames.It has a preloader.swf and game.swf.The preloader.swf loads the game.swf.The game.swf has 4 frames.In the first frame is given to the user the options to play the game (clicking a button "playGame" on "click" event) and to set the sounds settings (clicking a button "options" on "click" event).So far so good.
When the user clicks "playGame" I send the user to frame 2, where it has the option to select a game level using the arrow keys. So within the playGameListener I registered two keyboard events one for KEY_UP and another for KEY_DOWN. So, to have sure that it´s working, I added a trace for each keyboard event listener. But I´m not getting any message in the output window while pressing left arrow or right arrow or any arrow.
So I learned that KeyboardEvent only dispatches an event if the flash player has focus.Well I think the flash player has never losed focus in this process.I´ve registered two events for Event.ACTIVATE and Event.DEACTIVATE and inside its listeners I added a trace with a message. Flash outputs me a message if I minimize the flash player window or if I maximize the flash player,but not while the game.swf´s frame transition.The listeners for the KeyboardEvent works only when I press at the flash player, then I receive the messages from the KeyboardEvent listeners.
I have two buttons each in its own sprite now I want to listen for mouse overmout and click event on both. In a way that if you roll over button1 its color changes but at the same time button2 color changes as well.
To be more specific lets suppose I have a graphic button like map picutre for a country like UK and then I have text button for UK as well. What I want now is that when user either scrolls over UK map the map button color changes but at the same time the color for UL text button changes as well. same goes for click and out events for the two.
May be my title doesn't clearly reflect to what I am saying. Let me demonstrate with following example
[Code]....
Instead of doing this type of event listening,is there a way, by which the final class can listen to "firstDispatch" event without going through its object as shown above
I have a parent swf and eight child swfs. The child swfs are loaded into an array at runtime on the parent swf using a Loader. I have buttons and functions on and in the parent swf to change out the child swfs. This all works just fine but here is my issue. On each of the child swfs I have buttons that need to call the functions in the main swf to change out the child swfs. The program is an interactive virtual tour and I want to be able to click on a door and have the next room's swf displayed in the parent swf. I'm trying to do this by dispatching an event from the child swf
ActionScript Code: mainPanorama.bedDoor.addEventListener(MouseEvent.CLICK, dispatchBedroom); function dispatchBedroom(e:Event):void { dispatchEvent(new Event("loadBedrooms")) }
that needs to be heard by the parent swf and the appropriate function called.
So far this specific code keeps telling me that addEventListener is not a function. I've tried quite a few variants of stage, this, and parent combinations in place of objectsArray but unfortunately something in the parent swf is not hearing the event dispatch.
Does flash dispatch any event just before it's closed?e.g. When the user closes the browser? searched the documentation and there's nothing. I thought the stage should dispatch an ventIf there isn't any can I make a custom one?
I'm working on a project and had a question related to another thread I recently posted earlier this week regarding an area I was a little stuck on..While I did manage to resolve most of my issue, there's still a piece of the puzzle that's missing. I basically have one main container swf that loads several external swfs into a MC and cycles through an array of external files. I have navigation buttons so the user can click next to proceed through all of the external content files. My goal here, is to not have the "next button" become active until after the external files are done playing, so they can't skip ahead.
I currently have this working by having the external swf dispatch an event (from its final keyframe) to the main swf telling the main swf it's done playing, and then activates the next button on completion. This works great; however, I can't seem to get it to dispatch this event on any of the sequential swfs -- it only does this for the first swf initially loaded. Is there a way to "reset" the event to detect the end of the other swfs and continue in this fashion? Or another possible solution so I can apply this to each external swf?Here is the code I have in the main container swf:
Code: //Array of external swfs var contentArray:Array = new Array("content1.swf", "content2.swf", "content3.swf");
What I am trying to do is build some kind of Loader-SWF that loads several animations (swf-files) and then plays them back one after the other.
What I am struggling with at the moment is how to find out when the first animation has finished and then switch to the second one. Since the Loader-Object I use to load the swf doesn't seem to dispatch a suitable event I thought I'd just do the following on the last frame of the animations I am loading:
Code: stage.dispatchEvent(new Event('nextClip')); and then have this in my "Loader":
This works fine when I just have my first animation clip dispatch the Custom Event, but as soon as I add the code to all the other animations it will throw an 1009 error (referring to the last frame of the newly added animation) as there somehow seems to be some confusion regarding what "stage" is referring to now.
Then I have a custom component that also has a dataProvider. How do I get it to dispatch a collection change event when its dataprovider finishes loading?From what I've read, I can't do it. Will dispatching a propertychangeevent work?
UPDATE:I have a custom component that I call 'SortingComboBox' but it is not a ComboBox at all; it extends Button and I set is dataProvider property to my arraycollection, model.product (which is an arraycollection). how I use the dataProvider in that component:
code
[Bindable] private var _dataProvider : Object; public function get dataProvider() : Object {[code]..........
In the createChildren() method of this component, I use this:
The problem is I get Error: Error #2094: Event dispatch recursion overflow. Why does removechild keep getting called if this.parent does not exist? Why doesn't removing event listeners work?
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?

I'm just starting to build my first proper OOP piece.I have on stage two manually placed MCs.One is viewer_mc:ViewerClass and one is menu_mc:MenuClass.They each have their own class and there is a document class...
PHP Code:
package { import flash.display.*;[code]....
So I can call the public method of either class from the other class.However, I am now trying to understand custom events and dispatching them with parameters.which uses a custom event class.This works fine when the dispatchevent and listener are both in the viewer class, but when the dispatchevent is in the viewer class, and the listener is in the menu class I can't get it to work.I suppose for my purposes I don't really need to use the custom event class, I can just call the respective classes' public functions but I just wanted to try and understand how it works.Here's the pared down version of menu class...
PHP Code: package classes { import flash.display.*; //some other imports[code].........
I am developing a project where ClassA creates the instances of ClassB , ClassC and ClassD and adds the eventsDispatcher with them. ClassB and ClassC are able to dispatch the events back to ClassA which is fine. But ClassD is not dispatching the event. It only dispatch the event only when I call the dispatchEvent(new Event(Event.Complete)) function after giving 1 Second delay.
Let's say function foo() is executing. Suppose that an external event occurs, for which you have a handler. Will function foo() be interrupted so that the event handler can be executed? What is the order of execution in this situation?
I got a question about event dispatching in flex.my goal is to get a custom event loaded up with some data and than bubble up to the eventlistener. my main application has and AMF service request inside which calls an service class. that class is supposed to dispatch an event when the AMF service request returns a result or fault and the main application is listening for that event.so inside my mainapp i add and listener like this:[code] However, this event never reaches the main application. Looking closely to it with the debugger, i found out that when the event is dispatched the listeners property of it is set to null.
I'm trying to dispatch a custom event from a custom ItemRenderer. This is my custom event package events { import customClass.Product; import flash.events.Event; public class CopyProductEvent extends Event { public static const COPY_PRODUCT:String = "COPY_PRODUCT"; public var picked:Prodotti; [Code] ..... The event from the function is dispatched correctly... I can't intercept it..
I've written lots of hierarchical menus in AS2, am happy with XML, recursion and the Compound design pattern.owever, I'm about to built my first AS3 menu system, and what I want to know is where do people usually add their event listeners? Should I be adding them on each menu item, or just one on the whole menu system, and use event bubbling to capture and respond to clicks, rollouts, etc.
I have a class name ImageLoader that is used to load image and the dispatch a complete event when the image is loaded. This class is implementing singleton design pattern which means that only one instance is created always for this class.
Everything is working fine it is loading the image but in the initListener function i am dispacthing a complete event to let the other class Content (which passes the image name to this class ) that the image is loaded and you can access it now.
BUt the problem is the event is never dispatched or may be it is but I am not catching it properly here is code for my ImageLoader class.
It's me back with my fighting game questions. Basically, in the frames of the animations, events are dispatched. When one is being dispatched, I dont want the other one's function to be performed...I'm probably making this alot more confusing than it is supposes to be... If you can just picture it, in a fighting game I dont want the enemy to take damage, while both he and the player are colliding and attacking (whichever one was attacking first). geez that was a ramble.[code]
