ActionScript 3.0 :: Making An Object That Implements IEventDispatcher?
Feb 2, 2010
I'm interested in making an object that implements IEventDispatcher.
Does anyone know what the goes in addEventListener(...) dispatchEvent(...) etc. ?
My goal is to create my own simple Button that listens to mouse events, not 100% sure about the entire process (probably use hitTest and a single invisible pixel to trigger mouse events), this object extends BitmapData (Not an IEventDispatcher) so i have the option to use pure pixel rendering + mouse control.

I haven't used the implements keyword before, and I've been trying to use it to implement the IEventDispatcher class to see if this would allow me to use addEventListener() in a class that extends Object (this is my understanding of what it's for - correct me if I'm wrong).My class is like this:
package
{
import flash.events.Event;
[code].....

So basically I have this map. On this map I have points, and when you click on these points it goes to a URL.The code setup is as follows:
Arrays to define the movieclip locations and another for the urls (this one is an associative array). I then create a function loop to make an event listener for each point. When the point is clicked it will run another function that handles the URLs. The URL function is to grab the target point that has been click, use the url array type to find the key, and then throw it in to the URLRequest.
So far I have this code:
var places:Array = new Array();
places = [
map.paulsens, map.paraburdoo, map.plutonic, map.wiluna, map.gwalia, map.wallaby,
map.sunrise, map.moora, map.marvel, map.flyingFox, map.ernest, map.rosebery,
[code]....
So it's obvious to me that the openLink(); function isn't doing what I want it to. I can kind of guess because event.target isn't being turned in to a string or not pulling the array's type?

I am getting the error: warning: unable to bind to property 'Description' on class 'Object' (class is not an IEventDispatcher)
this is only when the data is bound to a List as an ArrayList, though. I had it in a Datagrid before (just as an Array) and it did not cause any issue. I'm not expecting to be able to bind any data back to the class 'object' not even sure which object exactly it's referring to.
My list data-provider is an ArrayList.. populated by a result event from an SQL query contained in another class:
private function loadDayComplete():void
{
var Meals:Array = _day.MealResults;
[Code].....
The day class I have is a data holder to get all the data (from several tables) for a 24 hour span.. I have classes for each individual datatype for editing them. But I'm not sure do I even need to worry about the warning if I don't plan on editing the values? it completely spams the console though whenever I touch anything, so I really would like to get rid of it. I tried an object proxy as I saw described elsewhere but nothing changed. The text is in label fields right now anyway, which can't even be edited.

we have following class
[Code]...
If you run these, you'll notice that the MXML-component can't hear the event. The question is simple, is there some way of getting the Event-metadata tag to work WITHOUT extending EventDispatcher? I would like to keep this class independent and use object composition as much as possible. And no, I don't want to use ActionScript addEventListener in the MXML-file. It doesn't tell the developer anything like good old Event metadata tag, and besides, that is not the point of this example. :)

I am overriding the addItem() function of an array collection and I would like to detect if the added item implements a particular interface. Previously I used the, is operator to detect the class type, but now that I am using an interface for classes I would rather test to see if the object implements the interface. I expect I could just try and cast the object as the interface and see if it's not null. Is this the best way to do it? I could also just create a new addFunction() that only accepts objects of the interface type.

Is there any non-hacky way to determine wether a class' superclass implements a particular interface?
For example, assume I've got:
class A extends EventDispatcher implements StuffHolder {
protected function get myStuff():Stuff { ... };
public function getStuff():Array {
[Code].....
How could I perform that super is StuffHolder test in a way that, well, works? In this case, it always returns true.

How can I test if a class reference implements an interface? Note that the is and instanceof operators do not work with Class references.
Example:
public function set someClassref(value:Class):void

if(value is IMyInterface)[code]........

Not sure if this is possible but I would like to reflect a swf or swc file selected by the user at runtime to find any classes that implement a certain interface. Can this be done or do you actually need a reference to the class you want to reflect using describeType();
Note - this would be done in actionscript.

In ActionScript 3.0, there are a few ways to check a class's extension. For example, if I want to know of a custom class extends Sprite I could use the is operator:
trace(MyClass is Sprite);
Or I could use flash.utils.getQualifiedSuperclassName:
trace(getQualifiedSuperclassName(MyClass));
I would like to accept a class as an argument and check to see if the passed class implements an certain interface. Is there an equally simple or common way to check if my custom class adheres to an interface? Perhaps something like:
trace(MyClass implements IMyInterface);

So far I've worked out moving sideways and collision detection, which were both pretty easy.What I need to figure out is how to make my movie clip jump. I have a jumpheight variable set at 50, so I want the Y value to increase gradually until it peaks 50 pixels from where it started, then gradually come back down until it collides with a solid object. But I can't really figure out how to do that. I've got this:
Code:
onClipEvent (enterFrame) {
if (Key.isDown(Key.CONTROL)) {

How do i make Obj1 move to Obj2 without easing? I want it to move Obj1 to Obj2 "walking" not "directly" by setting its _x and _y values.
Example for code with easing:

_y = 0;

Say I am moving an object around on the stage, walking from point A to B across the stage. I want to make the object the center, so the stage is centered on the object, so when I walk from point A to B the stage moves with me.

I'm newbie in Flash and action script, just start learning T__T...
onClipEvent (load) {
speed=10;
} onClipEvent (enterFrame) {
if (key.isDown(key.RIGHT)) {
_x+=speed;
} else if (key.isDown(key.LEFT)) {
_x-=speed;
} if (key.isDown(key.UP)) {
_y-=speed;
} else if (key.isDown(key.DOWN)) {
_y+=speed;
}}
Is that making the object moving to left and right?

Is there a way to generate an instance of a class that implements an interface based on the name of the class?
I am trying:
var ClassReference:Object = getDefinitionByName("movement.OuterSpaceMovement") as IMovement;
var m:IMovement = new ClassReference as IMovement;
trace("startup..." + m);
-But I am getting an error message ReferenceError: Error #1065 (OuterSpaceMovement) not defined.
I have several classes that implement the same interface (IMovement) but I need to be able to generate new instances of these classes and then pass these instances as a datatype (IMovement datatype) to other classes...
So then I tried:
var ClassReference:Class = getDefinitionByName("OuterSpaceMovement") as Class;
var m:IMovement = new ClassReference() as IMovement;
and this doesn't seem to work...but the following
var m:IMovement = new OuterSpaceMovement();

recently, I research for the collection framework, and find LinkedSet(AS3Commons collection framework,it is a good opensource framework) written in ActionScript, but it can't use as dataProvider in ComboBox or DataGrid, because only implements ICollectionView can use as dataProvider. So I want to try if a class implements ICollectionView can work or not. I know Flex has build-in class implements ICollectionView, but I only want to define a class not use build-in class. The class as simple as possible.(can work is enough)

I'm trying to load a RSL library into a flash animation developed with Flash CS5 IDE, that extends a custom class and implements an interface. I have reduced the problem to the simplest setup and find that I can have my main class extend another class or implement an interface, but not do both at the same time if I want to load an RSL.I have a very simple class to extend:
import flash.display.Sprite;
public class MySprite extends Sprite
{[ code]...........
but if I want both I get the VerifyError: Error #1014 with MySprite not found and ReferenceError: Error #1065.

I'm creating pages with text supported by wav files for training. on the bottom of the page is a progress bar. I want to make a button that when clicked will permenantly
raise the alpha of a movie clip (on a different layer) to 100%. (it is currently set to 0) within the movie clip (hazpop) is a button that will turn the alpha to zero (click to close window) so in theory (not as2) it should be: on mousedown alpha.hazpop=100 I've been combing the forums for days and no-one is talking about alpha.

I've been working a game where you drag an object onto a grid. This then 'grows' over time. Once it has taken about 5 seconds to grow, the player can click on it (only 5 seconds for debugging reasons) and 'collect' money as a result. The problem I'm having however. Is that I cannot remove it once the timer even has occurred. I get the 2007 parameter error, child must be non null. Problem is, I don't see how it is null as I've already defined it? I'm rather lost - and somewhat new to AS3.
Code:
private function placeSeeds(e:MouseEvent):void {
var seedsRow:int=Math.floor((mouseY-300)/75);
var seedsCol:int=Math.floor((mouseX-150)/65);
// check tiles
if (seedsRow>=0&&seedsCol>=0&&seedsRow<3&&seedsCol<3&&itemsArray[seedsRow][seedsCol]==0) {
var placedSeeds:lolMC=new lolMC();// constructs the object
