I am new here just signed up and I did not find information on how to classify this topic on specific section.
I am using adobe flash professional to create a small banner to auto load one of my own URL for analytics. Is this possible? I found one solution on another user's topic which was (AS 3):
var req:URLRequest("http://your_request");
var loader:URLLoader = new URLLoader ();
loader.addEventListener(Event.COMPLETE, onLoadComplete);
loader.load(req);
private function onLoadComplete(ev:Event):void
{
var result:String = ev.target.data;
}
But this doesn't seem to work. How can I test that the full webpage is loaded 'invisibly' in the background? If "http://your_request" has cookies for example, I can check if the cookies were created, but I do not know if with this method I'll load the cookies to check if this is working at the first place.
There is no way to get http-cookies natively. But you can do this with a js-helper-function and an ExternalInterface.call. See this answer: How do I access cookies within Flash?

I just created my first game, and am having some problems. I uploaded to Kongregate(but didn't publish yet), and in the preview the external files(music and three pictures) don't load. The rest of the game works fine.
If I try to change it so there is a zip with the assets in it and change the directory in the code, it falls apart.
I'm using FlashDevelop, so everything is programatic. I noticed the swf is only a few kb large, so is there anyway to compile the assets into the swf file and load them that way, or do I need to do something else?
Please help, and thanks in advance.
Ok, let me explain then. Lets assume you have your main module game.swf that loads some image asset.jpg from the same folder. You test it locally, it works just fine. You put game.html, game.swf and asset.jpg on your site http://niamke.com/ and it still works. Then you publish your game as http://kongregate.com/games/niamke/myniamkegame/ and it suddenly stops loading asset.jpg.
Why
HTTP requests from Flash Player are handled via browser. So the browser gets a request for "asset.jpg" from Flash Plugin instance. There could be all kinds of content (including several Flash Apps) from several different domains within one page, so browser does not bother to figure the correct address out, and plainly tries to load in relatively to the topmost HTML document, basically http://kongregate.com/games/niamke/myniamkegame/asset.jpg which is not there.
How to avoid it
You should create a small piece of code that figures the correct URLs for the files you load. As soon as your content attached to Stage, any display object can access the loaderInfo object which contains the absolute SWF URL.
Usage
Files.parseURL(loaderInfo.url);
var aLoader:Loader = new Loader;
var aRequest:URLRequest = new URLRequest(Files.baseUrl + "asset.jpg");
Loader.load(aRequest);
Implementation
package
{
public class Files
{
// Long live Bill Gates and Windows and backslashes.
static public function figureSlash(value:String):String
{
var aSplit:Array = value.split("/");
var oSplit:Array = value.split("\\");
return (aSplit.length >= oSplit.length)? "/": "\\";
}
static public var baseUrl:String;
static public var systemSlash:String;
// Supposed to dissect the SWF url in order to
// process relative resource file urls properly.
static public function parseURL(value:String):void
{
// Figure correct slash.
systemSlash = figureSlash(value);
// Split SWF URL into Array and remove SWF name.
var aSplit:Array = value.split(systemSlash);
aSplit[aSplit.length - 1] = "";
// Obtain the SWF root folder.
baseUrl = aSplit.join(systemSlash);
}
}
}
A comment brought me to the conclusion below:
"I just linked the URLRequest to where the files were hosted online."
I'd like to display, in my app, only a part of a web page.
On this website, I'd like to display, in my app, only the div id "MovieCart".
What should I write in my as3 code in order to do so ?
For now, I have this line :
webView.loadURL("http://www.cinecity.nc/Cinecity/Film/40565");
But, of course, it's displaying the fullwebpage.
EDIT
So, I've tried this :
webView.addEventListener(Event.COMPLETE,onComplete);
var res : String = ExternalInterface.call("function(){return document.getElementById('movieCart').outerHTML}");
var urlOfMovie: URLRequest = new URLRequest("http://www.cinecity.nc/Cinecity/Film/40567");
var loaderMovie:URLLoader = new URLLoader();
loaderMovie.load(urlOfMovie);
webView.loadString(res);
But, as it's an AIR app, ExternalInterface.call can't be call. Any idea ?
Here is one easy way you can accomplish this:
//First, load the full page as you're currently doing:
webView.addEventListener(Event.COMPLETE, webLoadComplete); //listen for when the load is finished
webView.loadURL("http://www.cinecity.nc/Cinecity/Film/40565");
//runs when the load finishes
function webLoadComplete(e:Event):void {
webView.removeEventListener(Event.COMPLETE, webLoadComplete); //stop listening
//second, invoke the following Javascript on the page which assigns the `MovieCart` element as the html for the whole document body
webView.loadURL("javascript:document.body.innerHTML = document.getElementById("MovieCart").outerHTML");
}

I need help with AS3 make downloading MP3 files in the background mode. Man goes to my site and it will automatically load MP3 file on his computer and plays it. I read these examples here http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/net/URLLoader.html but do not know how to do it? Prompt what code and how to use it properly?
You can directly load a Sound object with an URLRequest instead of using a separate Loader or URLLoader. A code could look like this:
// this code should reside in a function somewhere
var request:URLRequest = new URLRequest("http://your.site.com/your.mp3");
var sound:Sound = new Sound(request;
sound.addEventListener(Event.COMPLETE, completeHandler);
// this function should be at top level anyway
private function completeHandler(event:Event):void
{
var loadedMP3:Sound = Sound(event.target);
if (loadedMP3) loadedMP3.play();
}
Extra error handling is up to you.
Have read many similar but no solutions: I'm trying to do something (that i think is) really simple,
Take a photo from gallery or camera - and POST this to a URL. No saving / returning to application. The PNG is just used by the webpage in display and user moves onward.
public function postPicture():void {
PNGEncoder2.level = CompressionLevel.FAST;
var encoder : PNGEncoder2 = PNGEncoder2.encodeAsync(_bitmapData);
encoder.targetFPS = 12;
encoder.addEventListener(Event.COMPLETE, function (e):void {
var png : ByteArray = encoder.png;
var header:URLRequestHeader = new URLRequestHeader("Content-type", "application/octet-stream");
var jpgURLRequest:URLRequest = new URLRequest("https://myurl.com/mypage");
jpgURLRequest.requestHeaders.push(header);
jpgURLRequest.method = URLRequestMethod.POST;
jpgURLRequest.data = png;
navigateToURL(jpgURLRequest, "_blank");
});
}
Also to note, we're getting some odd characters on the end of the URL: C9%90NG
Hunch is that I'm decoding and then not encoding properly before sending i.e. these characters some part of raw image info.
When I test from chrome POST extension with another image, server side stuff works fine so guessing a problem with AS3.
basically its working when I use chrome to browse > my.png and POST it at the page. Am I missing something with the AS3 png encoder? i.e. how to turn that bmpdata into a 'file' rather than an array of bytes.
thankyou
You need to use multipart upload. It's a common situation with a well defined standards for that. You can implement it by yourself but it will take some time and efforts.
What I've used before is the Multipart URLLoader Class provided by Eugene Zatepyakin, one the best Flash guru's out there :)
It's some kind of old but does the job extremely well. You can add variables, files, whatever content you want to your loader and simply submit it. There are examples with the php side of the thing so you can understand what's going on.
I am getting a mysterious result when trying to load profile images from a logged in Facebook user's friends list into an as3 canvas app. In pretty much every (non-facebook) application I've made where loading an image is required I use the following:
private function loadPic():void
{
var url:String = Facebook.getImageUrl(_friendslistObjectArray[_loadCount].id);
_picLoader = new Loader();
var req:URLRequest = new URLRequest(url);
_picLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onPicLoaded);
_picLoader.load(req);
}
private function onPicLoaded(evt:Event):void
{
_picLoader.contentLoaderInfo.removeEventListener(Event.COMPLETE, onPicLoaded);
// grab image from loader event to use it
var image = evt.target.content;
trace("this trace won't even show up and the program silently fails unless the line above this is removed");
_loadCount++;
loadPic();
}
I can't retrieve the image from the event object, and I am given no error at all. It all just fails silently. If I remove the line var image = evt.target.content, the process runs through the whole array.
I can't think of any reason this would occur. Furthermore, if I look in firebug's net activity, I see I see the images get loaded as long as I do not have the line I just mentioned included. I just can't seem to get the image data from the event object to add it to stage or a container movieclip.
This should be very easy. I'm racking my brain here trying to figure out what I missed or what is wrong. Any thoughts? Thanks!
Found the answer:
This line:
Security.loadPolicyFile("http://profile.ak.fbcdn.net/crossdomain.xml");
Placed right before _picLoader.load(req); fixes the problem.
It was a crossdomain error, but for some unknown reason the error did not report until I threw var image = evt.target.content; into a try/catch and read the error message.
Props to this post for the answer:
Load profile image from Facebook with Actionscript 3
the evt.target should be a LoaderInfo object, try the code here:
var image = (evt.targe as LoaderInfo).loader.content;
