Ross,

The addEventListener would be on the instance of your "different class than the 
HTMLLoader".

myOtheraClass.addEventListener(MyCustomEventClass.MYCUSTOMEVENT, 
onMyCustomEvent)

Make sense?

Thanks Jason... Let me ask one question to try to clarify this for me.  If I 
have the dispatchEvent that broadcasts the URL of my HTLMLoader in a 
onLoadComplete function and I want to listen for that event in a different 
class (for example I want to put the URL in a textbox that is created in a

I'm not sure why my head is not wrapping around this, but thanks for all your

To add on to David's fine reply, Ross, you're close, but not quite - this is 
how I write custom events, I think you'll want to do something like this 
instead - this works great for me:

To write the event:

package events
{
import flash.events.Event;

public class MyEvent extends Event
{
public static var MYEVENT1:String = "myEvent1";  
public static var MYEVENT2:String = "myEvent2";

public function MyEvent(type:String, bubbles:Boolean = false, 
cancellable:Boolean = false ) 
{
super(type, bubbles, cancelable);
}

}

}

Then to dispatch:

import events.MyEvent;

dispatchEvent(new MyEvent(MyEvent.MYEVENT2, false, true));

Then to listen and react to dispatch:

myObject.addEventListener(MyEvent.MYEVENT2, onMyEvent2)

public function onMyEvent2(event:MyEvent):void
{
Trace("myEvent2 heard!");
}

An event is just a message object.  Just because one gets created
successfully does not mean it is being delivered.  dispatchEvent() is a
method of the EventDispatcher class, which is a superclass of many classes,
including DisplayObject.  You need to listen for the event (with
addEventListener()) on the same EventDispatcher where the event was
dispatched. (Except in the case of events that bubble, but that's another
topic.)

For example:

public class MyWindowHolder extends Sprite {
  public function init(): void {
var a: MyWindow = new MyWindow();
a.addEventListener( MyEvent.EXCLAMATION, onExclamation );
  }

  private function onExclamation( event: MyEvent ): void {
trace("ouch!");
  }
}

public class MyWindow extends Sprite {
  private function injury(): void {
this.dispatchEvent( new MyEvent( MyEvent.EXCLAMATION ));
  }
}

Hope this helps,

actually, you can encode to on2 with ffmpeg, it takes a bit of tweaking, but
it does work(with the help of some other programs), here's the link(actually
not sure it's legal, it depends on the on2 codec which used to be
distributed):

Re: [Flashcoders] Custom eventListener

2008-12-19 Thread John McCormack


Ross,

I'm no expert but I think this is correct:
As long as your object is decended from the EventDispatcher class (all 
display objects) you can attach a listener to it.
Let's say you have a Text field called myObject in another file/class 
then you can specify the event name, as explained, with something like:


myObject.addEventListener(MyEvent.MYEVENT2, onMyEvent2)

public function onMyEvent2(event:MyEvent):void
{
Trace("myEvent2 heard!");
}

I used to have problems specifying what to listen for, i.e. the event's 
name.
The MYEVENT2 above is actually a string but you are supposed to use this 
capitalized version.

The string is defined in the MyEvent class as
public var static const MYEVENT2:String = "SomeNameIdentifier";

Jason's example has "import events.MyEvent;" and so any public static 
variablesin MyEvent.as are visible.
If the MYEVENT2 string is defined as "var public static" in the a class, 
it is visible to other files that import the class.
If it had been defined without the "static" keyword then the variable 
would belong to instances of the class, not the class, and would not be 
visible outside of the file.


I liked Jason's lamp and switch example and would like to know more 
about using it more effectively in design patterns.


John

I hope I am not being a pain about the threads being kept sorted, but 
this information resource you are creating is really precious.

RE: [Flashcoders] Custom eventListener

2008-12-19 Thread Merrill, Jason

>>" But all those things I can do with normal events, I guess.

So my wordplay aside, given my example, you would not use a "normal event" for 
this type of thing (having a class check data states and broadcast a 
notification to any listening classes that a certain data state, i.e. the 
machine is in the "on" state because all levers are pulled) - what kind of 
"normal" event are you thinking of?  I'm wondering if you're thinking of a 
tight-coupled relationship between classes where every time a lever is pulled, 
you check to see if all other levers are also pulled and then tell the 
lightbulb class to light up - that's not a good way to do it, it creates hard 
(i.e. tightly coupled) dependencies between classes.  I would instead do as in 
my example, broadcast that a certain state of the data (all levers pulled) has 
been achieved.  Then ANY other class, (i.e. the lightbulb, the Wonky Widget, 
the Funky Fan Button, etc.) can listen and react to that state of the levers.  
As you code, you want to loosely or completely de-couple relationships as m!
 uch as possible - depending on the size of the project, the larger the size 
and complexity, the more you will benefit from doing this.

I was simply showing you a simple example of how you would have a custom class

You might wanna read the docs for some basics on Events in AS3:
http://livedocs.adobe.com/flash/9.0/main/0138.html
http://livedocs.adobe.com/flash/9.0/main/0139.html

When writing cusom events, you can usually ommit the bubbles and
cancellable arguments, as those are false by default.

And you should always implement a clone() method:


Event class utility methods

There are two utility methods in the Event class. The clone() method
allows you to create copies of an event object. The toString() 
method allows you to generate a string representation of the properties
of an event object along with their values. Both of these 
methods are used internally by the event model system, but are exposed
to developers for general use.

For advanced developers creating subclasses of the Event class, you must
override and implement versions of both utility methods to 
ensure that the event subclass will work properly.


AFAIK, the toString() method is only useful for debugging purposes
(trace).

Re: [Flashcoders] round number to closet value of 8

2008-12-19 Thread Hans Wichman

Hey,

it cuts off the lowest 3 bits. These lowest 3 bits are 001, 010, 011 etc, so
1,2,3,4,5,6,7

But cutting off only the lowest three bits, will result in 0..7 being 0,
8..15 being 8, while you want 0..4 -> 0 , 5..12 -> 8, etc, so 4 is added.

But Benjamin can prolly explain better hehe since it's his trick :)

 Hi,
 I think you are looking for :
 function roundToEight (pVal:Number) {
  return Math.round(pVal/8)<<3;
 }
 although 44.9 and 44.4 will both return 48, don't you mean 43.9 and
 44.4?

 int(pVal + 4) &~ 7;

Indeed it looks very impressive. Could some explain what is does exactly?
