 I presume my removeEventListener works. 
You should be sure. So check it: 
 
trace(e.currentTarget.hasEventListener(Event.COMPLETE)); //true
e.currentTarget.removeEventListener(Event.COMPLETE, loaded); 
trace(e.currentTarget.hasEventListener(Event.COMPLETE)); //false

 So, how do I pass new values to fn loaded?
Just increment the vars. 
// Cascade layout 
displayObject.x = myX + 31; 
displayObject.y = myY + 31; 
myX += 20; 
myY += 20; 
 
Have you considered putting your url strings into an array instead of using
that awkward switch statement? 

I would also recommend writing a function that creates and returns
BevelFilter. Set 'myBevel' once (rather than running through the code
repeatedly) then apply it where appropriate. 
var myBevel:BevelFilter = createBevel(); 
function createBevel():BevelFilter{ 
var bf:BevelFilter = new BevelFilter(); 
bf.type = BitmapFilterType.OUTER; 
bf.distance = 10; 
bf.highlightColor = 0xFF; 
bf.shadowColor = 0x00; 
bf.blurX = 20; 
bf.blurY = 20; 
return bf; 
} 
 
// apply Bevel filter 
displayObject.filters = [myBevel];

How is that? I'm not iterating over that function, I call it as needed, so
myX, myY would be reset every time.

var loaderArray:Array = new Array();
loaderArray[counter] = new Loader();
loaderArray[counter].load(req);
loaderArray[counter].contentLoaderInfo.addEventListener(Event.COMPLETE,loaded);
}

My bad. It is not iteration. It is called onMouseOver, hence the value of
myX, myY cannot be predetermined nor iterated.

Re: [Flashcoders] Event.COMPLETE Question

2010-02-23 Thread Steven Sacks 
When loading bitmaps, your loader will NEVER be eligible for cleanup by the 
Garbage Collector unless you do ALL of the following in this order:


var bitmap:Bitmap = new Bitmap(Bitmap(loader.content).bitmapData.clone(), 
auto, true);

Bitmap(loader.content).bitmapData.dispose();
loader.unloadAndStop(true);
try {
loader.close();
} catch (e:Error) {}
// remove all event listeners from loader

This means that if you want the Bitmap from the loader, you should extract it 
using bitmapData.clone(), or your Bitmap will be gone when the loader goes away 
or the loader will not go away because there's still a reference to its BitmapData.


If you're pulling a Bitmap out of an anonymous loader by saying 
addChild(loader.content) you will never have another opportunity to get rid of 
the loader. That may be ok for your purposes, but this is a very good reason to 
addChild(loader) so you maintain a reference to the loader itself.


Unless you have a specific reason for not using addChild(loader) you should use 
the code block above.


It's important to note that you won't see your memory go down unless you force 
the GC to run after you null out all references to the loader. In AIR you can 
say System.gc().  In Flash, you have to use the unsupported LocalConnection hack.

Steven, 
I'm curious about the try-catch block. It seems unnecessary since,
presumably, this code would be called within an onLoadComplete function and
the URLStream would no longer be open. Is there a scenario where this would
not be the case?

Re: [Flashcoders] Event.COMPLETE Question

2010-02-23 Thread Steven Sacks 
If you call close() on a Loader and it fails for any reason, it will throw a 
runtime error that you can do nothing about. To avoid this, you should wrap it 
in a try catch.


The code block comes straight from Flex and it works. If you test it a bunch and 
close() never fires an error, then you can remove it.  It's really not that much 
overhead to keep it in unless you're doing hundreds of iterations per second.

I'm missing something. I added the variable loaderArray as an Array which I

identifying the e.target in the loader function:

var req:URLRequest = new URLRequest(path);
var loaderArray:Array = new Array();
loaderArray[counter] = new Loader();
loaderArray[counter].load(req);
loaderArray[counter].contentLoaderInfo.addEventListener(Event.COMPLETE,loaded);

var loaderInfo:LoaderInfo = e.target as LoaderInfo;
var displayObject:DisplayObject = loaderInfo.content;
displayObject.width = 257;
displayObject.height = 257;
displayObject.x = myX + 31;
displayObject.y = myY + 31;
var myBevel:BevelFilter = new BevelFilter();
myBevel.type = BitmapFilterType.FULL;
myBevel.distance = 10;
myBevel.highlightColor = 0xFF;
myBevel.shadowColor = 0x00;
myBevel.blurX = 20;
myBevel.blurY = 20;

addChild(displayObject);
e.target.removeEventListener(Event.COMPLETE, loaded);
}

Please help me see what I'm missing.

e.target isn't your loader info, its most likely the Loader itself.

the target is where the event bubbles from, and the currentTarget is what
was applied the listener

so what you are looking for is e.target.content and that is whatever you
loaded in

Your images are unlikely to load in the same order indicated by the switch

Your images are likely to display one top of the other, making it seem like

 e.target isn't your loader info, its most likely the Loader itself.

loader.contentLoaderInfo.addEventListener()

The LoaderInfo is the target of the event - that's what you added the event 
listener to.


trace(event.target);
[LoaderInfo]

Proof that the LoaderInfo is the target is easily derived by tracing the 
event.target.




Why don't you just do this?

loader.filters = [myBevel];
addChild(loader);
