I've been working on a program, but currently I'm stuck.
My problem is the .content statement in my script. Since I'm loading a PNG from the web I have the Local playback security set to "Access network only". When I load pictures locally (of course with settings at "Access local files only", and local URLRequests) the program works just fine, but when loading from the web the .content makes my program stop, I've found this out with lots of testing. It seems the .content only works when the SWF file only uses local requests, is this correct?
I know that I can use addChild(loader), but I need to get the PNG file out of the loader so that I can turn it into a bitmap and edit it. Any ideas? The script is below.
var loader:Loader = new Loader;
var ar:Array = [];
var teller:Number = 0;
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, paste);
knapp.addEventListener(MouseEvent.CLICK, neste);
function paste(evt) {
ar[teller] = loader.content;
ar[teller].x = ar[teller].width*teller;
addChild(ar[teller]);
}
function neste(evt) {
teller ++
loader.load( new URLRequest ("http://www.minecraft.net/skin/Notch.png"));
}
loader.load( new URLRequest ("http://www.minecraft.net/skin/Notch.png"));
Cross-domain policies prohibits image data manipulation for images loaded from another domain than the one the swf file is loaded from:

I'm using the flash debug player(version 16) and I'm trying to access a users photo from within flash as3. Firstly, the Security error i'm receiving, here it is.
SecurityError: Error #2122: Security sandbox violation: Loader.content: http s://graffiti-galore.herokuapp.com/fb/GraffitiGalore.swf?build=0001 cannot access http s://fbcdn-profile-a.akamaihd.net/hprofile-ak-xfp1/v/t1.0-1/c46.46.570.570/s50x50/398269_10152199084495525_2139734276_n.jpg?oh=29be37fd74f7d338a7b5c23b9aadd474&oe=5548F552&gda=1431395518_d142c304e8b8afa8df340e6cac093b29.

I'm using the free Heroku dino that is being offered and I'm simply doing a fetch call to the graph api users object. fetching the id,first_name, last_name,picture.
The picture url comes back as hosted on https facebook servers.

Links like the one above. For some reason i'm receiving this Security error whenever loading up the image from my flash as3 facebook app.
Below is the code i'm using to fetch the image.
[code]
public function setupPhoto(url:String):void
{
removeAllChildren();
var urlRequest1:URLRequest = new URLRequest(url);
this.loader1 = new Loader();
this.loader1.contentLoaderInfo.addEventListener(Event.COMPLETE, onCompleteLoadingImage);
this.loader1.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, onErrorLoadingImage);
this.loader1.load(urlRequest1);
//imageLoader = new ImageLoader(url);
//imageLoader.addEventListener(Event.COMPLETE, onCompleteLoadingImage);
//imageLoader.load();
}
private function onErrorLoadingImage(e:IOErrorEvent):void
{
debugPanel.writeLine("ERROR LOADING IMAGE!!!");
debugPanel.writeLine(e.text);
}
public function onCompleteLoadingImage(e:Event):void
{
//var sprite:Sprite = this.loader1.content as Sprite;
//updatePicture(sprite);
updatePicture1(this.loader1.content);
}
[/code]
this works for me with Facebook:
var lc:LoaderContext = new LoaderContext(true, null, null);
// now add the LoaderContext to your loader
this.loader1.load(urlRequest1, lc);
you don't have to create a LoaderContext every time, just create it once and use everywhere.
I am trying to call a swf from a link in as3. I searched on internet and i used this code
var my_Loader:Loader = new Loader();
var my_url:URLRequest=new URLRequest("http://gurselgunacar.web44.net/flash/yalitimhesabi.swf");
my_Loader.contentLoaderInfo.addEventListener(Event.COMPLETE, finishLoading);
my_Loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, errorHandler);
my_Loader.load(my_url);
function finishLoading(loadEvent:Event) {
addChild(loadEvent.currentTarget.content);
}
function errorHandler(errorEvent:Event):void {
trace("file missing");
}
as3 call link but i cant do anything in swf. In output flash give security error. And i tried crossdomain.xml thing and it didnt work :S
The file http://gurselgunacar.web44.net/crossdomain.xml does not exists. You should create one.
The Loader will always look for a crossdomain.xml file at the target server.
Humm. Try to add these Security things:
Security.allowDomain("*");
Security.loadPolicyFile("http://gurselgunacar.web44.net/crossdomain.xml");
And use this in the URLRequest:
var my_url:URLRequest=new URLRequest("http://gurselgunacar.web44.net/flash/yalitimhesabi.swf?" + new Date().getTime()); //this will avoid caching old swf.
I tested on a EXE projector and it seems to work.
I'm streaming an MP3 file in AS3. All is working fine (I can play it) but I'm looking to implement a 'seek' bar. This means I will need to cache the file (as it's being downloaded) and then access the cached data when the user seeks a specific time in the song.
The code to actually play the mp3 stream:
function openStream( stream )
{
var s:Sound = new Sound();
var req:URLRequest = new URLRequest(stream);
var context:SoundLoaderContext = new SoundLoaderContext(500, true);
s.load(req, context);
s.play();
}
So how would I cache the file as it's being downloaded and then access the data from the cache?
I know this is pretty far from a trivial task, so I would be grateful if you could even just provide a few links to some tutorials/docs/articles.
You do not need to cache the sound for this.
The downloaded sound data is is available as long as the sound object lives in memory.
So all you need to do is take the sound object outside the function into the class scope..
Also the play function returns the current SoundChannel used by the Sound.
private var snd:Sound = new Sound();
private var channel:SoundChannel;
function openStream( stream ) {
...
channel = snd.play();
}
To implement the seek functionality you may make use of,
bytesLoaded (To know how much of the sound is downloaded)
soundChannel.position (To know current sound position)
I have to do a very simple swf application able to show a series of pdf files.
Actually I was able to create on a single layer the menu interface (some buttons on frame 0 which redirect the user to other frames where the pdf should be showed).
Here my question:
I need a way to read the pdf inside the flash frame.
I've found a possible solution converting the pdf into an swf with FlashPaper 2
Now I wish to know how import the swf into the frame.
Reading some actionscript 3 guides I was able to create a container movieclip (a simple rectangle) into which I have loaded the swf with this code:
var swf:MovieClip;
var loader:Loader = new Loader();
var defaultSWF:URLRequest = new URLRequest("test.swf"); //test.swf is my converted pdf
loader.load(defaultSWF);
screen_01.addChild(loader); //screen_01 is the container rectangle converted to movieclip
I've used a container movieclip to mantain the other objects (menu buttons) on the frame, and ecause it helps with the swf positioning.
I seen it is possible also using loader.x and loader.y and it works.
Unfortunately I wasn't able to control width and height of the swf/pdf file (loader.width and loader.height exists but if used cause the swf will not loaded at all)
Solution:
I've found a possible solution at this page. The idea is to change swf scale only after the load process is complete (positioning can be done even before).
Anyway I had to use Actionscript 2 for this project because FlashPaper converted pdf doesn't work properly with AS3, I don't know why...
here the code:
//insert an emplty movieclip to load the swf, I've called it screen_01
var movLoad:MovieClipLoader = new MovieClipLoader();
var myListener:Object = new Object();
myListener.onLoadInit = function(thisMc:MovieClip) {
thisMc._height = 600;
thisMc._width = 900;
thisMc._x = 50;
thisMc._y = 30;
};
movLoad.addListener(myListener);
movLoad.loadClip("folder/flashpaper_converted_pdf.swf.swf",screen_01);
You can modify the size of the loader using scaleX and scaleY properties.
Keep them equals so the swf isn't stretched.
You may also want to listen to the COMPLETE event to do such a thing :
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onComplete);
function onComplete(e:Event)
{
var loader:Loader = e.currentTarget.loader;
loader.scaleX = loader.scaleY = 2; //Double the size of the loaded swf
}
EDIT: Due to the answer I change the code posted. I've added the Security.allowDomain("*") line and that line throws me an error. So, how can that be made?
I want to run an Action Script 3.0 Application into a Flex Application. To do this I've done the following:
<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication windowComplete="loadSwfApplication()" xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:Script>
<![CDATA[
private function loadSwfApplication()
{
// The next line throws me an error.
Security.allowDomain("*");
var urlRequest:URLRequest = new URLRequest("path/to/the/application.swf");
swfLoader.addEventListener(Event.COMPLETE, loadComplete);
swfLoader.load(urlRequest);
}
private function loadComplete(completeEvent:Event)
{
var swfApplication:* = completeEvent.target.content;
swfApplication.init(); // this is a Function that I made it in the Root class of swfApplication
}
]]>
</mx:Script>
<mx:SWFLoader id="sfwLoader"/>
</mx:WindowedApplication>
The problem is that in the calling of swfApplication.init(); the AIR Player throws me an exception:
Security sandbox violation: caller file:///path/to/the/application.swf cannot access Stage owned by app:/SWFApplicationLoader.swf.
This is because somewhere in application.swf I use the stage like this:
if (root.stage != null)
root.stage.addEventListener(Event.REMOVED, someFunction);
root.stage.stageFocusRect = false;
How can I load this swf application and USE the stage without any problems?
You can try to load your SWF temporarily into a ByteArray and then load it with your SWFLoader.
Don't forget to set allowCodeImport to true since your SWF has as code inside.
Of course be sure that your loaded swf is secure enough for your application since it will have access at all your property.
private function loadSwfApplication():void {
// load the file with URLLoader into a bytearray
var loader:URLLoader=new URLLoader();
// binary format since it a SWF
loader.dataFormat=URLLoaderDataFormat.BINARY;
loader.addEventListener(Event.COMPLETE, onSWFLoaded);
//load the file
loader.load(new URLRequest("path/to/the/application.swf"));
}
private function onSWFLoaded(e:Event):void {
// remove the event
var loader:URLLoader=URLLoader(e.target);
loader.removeEventListener(Event.COMPLETE, onSWFLoaded);
// add an Application context and allow bytecode execution
var context:LoaderContext=new LoaderContext();
context.allowCodeImport=true;
// set the new context on SWFLoader
sfwLoader.loaderContext = context;
sfwLoader.addEventListener(Event.COMPLETE, loadComplete);
// load the data from the bytearray
sfwLoader.load(loader.data);
}
// your load complete function
private function loadComplete(completeEvent:Event):void {
var swfApplication:* = completeEvent.target.content;
swfApplication.init(); // this is a Function that I made it in the Root
// class of swfApplication
}
If they are being loaded from different domains you are going to have to add a security exception - http://livedocs.adobe.com/flex/3/html/help.html?content=05B_Security_08.html
if its being run locally youre probably going to have to add them to the list of trusted files or folders in the settings manager - http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager04.html#117502
Assuming that the external SWF is also in the application directory, you could try loading it using the app:/ scheme:
var urlRequest:URLRequest = new URLRequest("app:/path/application.swf");
That may put it into the same security context as the main application.
One thing you may want to consider is that if you are trying to run a SWF from inside your application directory in AIR, AIR restricts execution of files. If you copy the file to a temp file and the run it (along with allowLoadBytesCodeExecution set to true) then it works.
var file:File = File.applicationDirectory.resolvePath("myFile.swf");
this.tmpFile = File.createTempDirectory().resolvePath("myFile.swf");
file.copyTo(this.tmpFile);
imagePreview.loaderContext = lc;
imagePreview.source = tmpFile.url;
it won't work for Flex Projectors.
Only we use SWFLoader and LocalConnection because they can communicate between external swf and main swf. Thanks for support!
Can you read my tutorial from Adobe's Forum
It is very better than MovieClip or Object-Callers
Thank for resolved solution :)
