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.

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 
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.

My bad. It is not iteration. It is called onMouseOver, hence the value of

Perhaps, but if I trace(displayObject) it traces as the bitmap, so I can use
that. Such being the case, I apply the bevel filter to the bitmap, which is
correct. Then I add the child to the default (stage) and it appears.
Everything good here. I presume my removeEventListener works.

But,,,that's not the problem!

THAT'S the problem. "myX" and "myY" are all the same value every iteration
(traced 'em). So, how do I pass new values to fn loaded?

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);

the target is where the event bubbles from, and the currentTarget is what

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

I'm missing something. I added the variable loaderArray as an Array which I
believe took care of one problem; however, I apparently am not correctly
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);
}

function loaded(e:Event):void
{
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;
displayObject.filters = [myBevel];
addChild(displayObject);
e.target.removeEventListener(Event.COMPLETE, loaded);
}

Please help me see what I'm missing.

All but the last Loader is being over written. 
Put each Loader into an array. 
 
var req:URLRequest = new URLRequest(path); 
loaderArray[counter] = new Loader(); 
loaderArray[counter].load(req); 
loaderArray[counter].contentLoaderInfo.addEventListener(Event.COMPLETE,loade

This way each Loader object is preserved in a separate element of the array.

[Flashcoders] Event.COMPLETE Question

2010-02-20 Thread Susan Day 
Hi;
I have this code:

public function thePic(x:int,
   y:int)
{
var path:String = new String();
switch (counter)
{
case 0:
path = "images/bracelet.jpg";
break;
case 1:
path = "images/brooch.jpg";
break;
case 2:
path = "images/chain.jpg";
break;
case 3:
path = "images/earring.jpg";
break;
case 4:
path = "images/necklace.jpg";
break;
case 5:
path = "images/ring.jpg";
break;
}
var req:URLRequest = new URLRequest(path);
var loader:Loader = new Loader();
loader.load(req);
loader.contentLoaderInfo.addEventListener(Event.COMPLETE,loaded);
}

function loaded(e:Event):void
{
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;
displayObject.filters = [myBevel];
addChild(displayObject);
}

If I trace "path" all paths print out in the iteration of "counter". The
problem is that "Event.COMPLETE.loaded" is apparently called only once after
the while loop terminates that increments counter (inside of which all of
the above code is contained). Please advise how to make function loaded fire
for each iteration.
