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]...
View 6 RepliesIs there a point of creating custom event class if i dont need to pass custom property with that event?
View 3 RepliesI'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 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.
//main
myplayer=new ClassPlayer();
myplayer.addEventListener("image_loaded",imageLoad edHandler,false,0,true);
myplayer.addEventListener ("watcher_loaded",watcher_loadedHandler,false,0,tr ue);
addChild( myplayer);

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.

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.
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.?
View 1 RepliesI was wondering if anyone knew how to create a .swc library file that could be used in Flash or Flex?I want to compile a custom package of classes into a .swc for use and download,
View 1 Replieslet's say I have a function in a package like this:
ActionScript Code:
package{
function traceObject(target:Object){
trace(target);
}
}
Now, I want to use this function in every flash application just like I do with
ActionScript Code:
import flash.display.*
1) How can I do that?
2) Can I have classes and constants in the same package too?
I am following these direction to the TEE to create a swc for all my custom classes but the swc never compiles. Is there another way of doing this?? [URL]
View 1 RepliesI have been using AS3 for over a year but only to create some web pages with simpleanimations using tween Engines like TweenLite etc. without having to rely too much on custom classes, one reason is obviously because I don�t know understand classes that well, even though I have created some re-usable classes like a class to add a glow or fade all my images or links when mouse over, but nothing fancy and I have been always curious as to how or what the pros do for small projects like a web site or a simple banner. 1- How often do you have to create custom classes for small projects, and for what parts of the project (navigation etc)? 2- Do you try to manipulate all of your MovieClips with classes? The reason for my question is because I want to start thinking more about classes (OOP) and stop witting all my code in the .FLA file or a class using the Document Class (which is no different than putting it directly on the .FLA file) IF classes is the way to go.
View 8 RepliesI'm trying to create a series of scripts that will create some custom event listeners.
I have three movie clips on my stage. One is a movieclip who's sole function is to hold array's and the event listeners. A second which moves around the screen. And a third that is motionless.
The problem is that the argument I want to test (which activates the custom event) is held within a string.
What I want to know is, how do you test to see if the string argument is true?
Is it something similar to this:
var myCode:String="1<0";if(myCode){
trace('one is smaller than 0'); //Strangely apparently one IS smaller than 0!!!
}
I think I'm going about this in the wrong manner, however this is the only way I can think of this working... (since I need to be able to dynamically create these events)
how can I create event handler for a class that I wrote myself?
Example:
Code:
class blah {
var ladida:string;
function blah () {
[Code]....
How is it possible to create an event handler, like lame.onChange? When the variable inside the class is changed, how would i be notified?
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?
View 2 RepliesI try to create game Guess Number using classes...On .fla file i'm planing to have components like Button and TextInput from flash components library.Also i created GuessNumber.as with class GuessNumber.
Problems:
1) next line now working:
playAgainBtn.enabled = false;
2) after clicking to button i don't see event:
guessBtn.addEventListener(MouseEvent.CLICK, checkingYourGuess);
I attaged files also all code here:

Is it possible to create a custom event listener other than the ones prebuilt in flash? I sort of know my way around the eventDispatcher class, but can I use it to create my own event to listen for?
View 1 RepliesThis 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.
This is my custome event
package events
{
import flash.events.Event;
import ui.map.MapElement;

How do I create a custom event class similar to ActionScript? What I mean by that is a class that I can use to fire off my own events, send the necessary data.
I don't wanna use third-party libraries like YUI or jQuery to do it. My goal is to be able to send a event that looks like this.[code]...
I am having is trying to add objects to stage. At the moment I can not put anything onto the stage unless it is in my Main document class (Main). How would I add to stage in my player class and bullet class?

Im currently trying to make an as3 fantasy football application for my uni course, but am finding it hard to seperate the code I have written into classes (which I have no been told is the only accepted method for the marking scheme). So far I have an external XML file containing player names load into a datagrid component, there is then an event listener on the table which loads the player images into their correct positions on a pitch when clicked. I need to write more functionality for it including saving to XML and error handling but feel I need to sort out the classes situation before I continue and it is in for this week.
Code:
import fl.controls.dataGridClasses.DataGridColumn;
import fl.data.DataProvider;
import fl.controls.ScrollPolicy;[code]..............
I am trying to create a custom resize event as part of a larger project to create a flexible liquid layout class.Basically, i want an object to listen for the stage.RESIZE event. If i can listen for this event from multiple objects, it solves my event firing problem.[code]
View 7 RepliesIn flash cs5 can you have AS3 classes in separate files like in flashbuilder. I just want to make games with just actionscript and no flex/authorscript
View 9 RepliesI'm laying out my code differently for my latest project. I am making a game, and I am keeping the Flash API stuff in a seperate class from the game logic.It's an aproach I've never tried before, and it's made me realize just how little I understand good OOP design.
what I'm trying to acomplish is this:
the Game class contains the step by step program flow of the game. it makes calls to a GameUtils class and DrawEngine class, these other classes have the Flash API stuff in themSo what is the best way to get the game class to control the other 2?
currently I have my program flow like this:
1. display splash image
2. add 'play' button
3. recieve click from button -->
[code]....
a more specific issue comes up at step 3: ..how do I have the game class progress without using a listener?I'm thinking of creating a method of the Game class that simply increments a step counter of a switch/case statement and keeping each step of my program flow in each case.
I hava a custom component and it contains a child icon. If I add a mouse-click event listener to both component(click-listener1) and icon(click-listener2), the event dispatched sequence is click-listener2, then click-listener1. I can understand it. But if I add a custom event to component (listener1), and mouse-click event to icon(listener2), when icon is clicked, the component will dispatch the custom event. In my test, the event dispatched sequence is listener1, then listener2. It doesn't match with event-bubbles rule.
In my opinion The custom event is dispatched in listener2, which triggers listener1. Why event flow sequence is not listener2, listener1?
In component.
icon.addEventListener(MouseEvent.CLICK, iconClickHandler);
private function iconClickHandler(event:MouseEvent):void
{

I have the following situation:I have an event handler, that displays small messages in my application's statusbar.These messages get passes through by dispatching events from custom components.A simple message could be like "HTTP Error" or so.Now, the main event listener, in the main application file, listens to the event dispatched by any custom component,but seems to refuse listening to events dispatched by custom AS classes.Here is my code for the custom event:
package main.events
{
import flash.events.Event;[code]..
So to sum it all up:
- The event listener listens to the custom event dispatched by any custom component.
- The event listener does not listen to the custom event duspatched by an AS class.
Those who wonder, the event really gets dispatched, that's why I added a trace call.
i am a bit embarassed to ask this, but i do this so much i have to ask. Occasionally, i need to pass/handle custom events on the fly. Rather than creating a whole custom event class, i will just do something like
Code:
myObject.dispatchEvent(new Event('thisCustomEvent'));
//and then handle it later

I have a custom Flex 4.5 component (to be used in a List) -
Game.mxml (represents a clickable playing table in a card game):
<?xml version="1.0" encoding="utf-8"?>
<s:ItemRenderer [code].......
But I never see the "game clicked: " trace. Does anybody please know why? I'm probably missing something minor, because I can see the "Clicked: 8946" trace.
This is similar to the question asked here. I am dispatching custom event "ShopEvent" but i am getting error "Type Coercion failed: cannot convert flash.events::Event@81ecb79 to com.events.ShopEvent"Note: Error is thrown from the parent custom component (3rd code snippet), I have added more details thereThis is my custom event. See the first constant, I copy pasted the event name in custom components.
package com.events
{
import flash.events.Event;

I use multiple custom classes like tweenlite, csvparse, papervision and many more. The way I do is put them in one central location and edit Flash CS4 Actionscript 3.0 settings to include that location.The problem I face is even though I don't use all the classes in a project, flash CS4 compiles every single class that is in that central location eventually increasing my compile time by minutes.
