Away3D fail to load AWD - actionscript-3

I've follow the tutorial from this link:
http://www.adobe.com/devnet/flashplayer/articles/creating-games-away3d.html
But the code seem like got problems with it that I can't even load the 3D vase.
Here is the code:
package
{
import away3d.containers.View3D;
import away3d.events.LoaderEvent;
import away3d.loaders.Loader3D;
import away3d.loaders.parsers.Parsers;
import flash.display.Sprite;
import flash.events.Event;
import flash.net.URLRequest;
public class Main extends Sprite
{
private var _view:View3D;
private var _loader:Loader3D;
public function Main()
{
_view = new View3D();
_view.backgroundColor = 0x666666;
_view.antiAlias = 4;
this.addChild(_view);
this.addEventListener(Event.ENTER_FRAME, onEnterFrame);
Parsers.enableAllBundled();
_loader = new Loader3D();
_loader.addEventListener(LoaderEvent.RESOURCE_COMPLETE, onResourceComplete);
_loader.addEventListener(LoaderEvent.LOAD_ERROR, onLoadError);
_loader.load( new URLRequest('vase.awd') );
}
private function onResourceComplete(ev:LoaderEvent):void
{
_loader.removeEventListener(LoaderEvent.RESOURCE_COMPLETE, onResourceComplete);
_loader.removeEventListener(LoaderEvent.LOAD_ERROR, onLoadError);
_view.scene.addChild(_loader);
}
private function onLoadError(ev:LoaderEvent):void
{
trace('Could not find', ev.url);
_loader.removeEventListener(LoaderEvent.RESOURCE_COMPLETE, onResourceComplete);
_loader.removeEventListener(LoaderEvent.LOAD_ERROR, onLoadError);
_loader = null;
}
private function onEnterFrame(ev:Event):void
{
_loader.rotationY = stage.mouseX - stage.stageWidth / 2;
_view.camera.y = 3 * (stage.mouseY - stage.stageHeight/2);
_view.camera.lookAt(_loader.position);
_view.render();
}
}
}
Any idea where the error is? Or is it got any tutorial that teaching how to load AWD files into flash?
Thanks.

I would suggest you to use AssetLibrary to load your Model, its very simple and easy to handle all the things that models contains,
AssetLibrary.addEventListener( AssetEvent.ASSET_COMPLETE, onAssetComplete );
AssetLibrary.addEventListener( LoaderEvent.RESOURCE_COMPLETE, onResourceComplete );
AssetLibrary.addEventListener( LoaderEvent.LOAD_ERROR, onLoadError );
for detailed example check This
I hope it helps you

delete "Parsers.enableAllBundled();"
try this:
AssetLibrary.enableParser(AWD1Parser)
or
AssetLibrary.enableParser(AWD2Parser)
or
var aWD2Parser:AWD2Parser=new AWD2Parser();
_loader.load(new URLRequest('vase.awd'),null,"vase.awd",aWD2Parser);

The vase AWD file adobe has with their tutorial is no longer valid. The AWD spec changed and adobe never updated their tutorial. You will usually get an End Of File error if you try to load it.

Simple Camera in Actionscript/flex How to?

I am having no luck with trying to create a simple camera in actionscript. I don't want any controls- just a stage asking for permissions, then a livevideo of me in a window. Nothing fancy
Here's what I have so far: (the latest failure...)
package {
import flash.display.Sprite;
import flash.media.*;
public class FlashCamera extends Sprite
{
var cam:FlashCamera = Camera.getCamera();
var vid:Video = new Video();
vid.attachCamera(cam);
addChild(vid);
}
}
It's throwing this error when I try to compile this:
call to a possibly undefined method getCamera through a reference with static type Class
I'm compiling with flex in the windows command line like this:
(path to SDK)/bin/mxmlc Camera.as
Mind you, I am new to actionscript/flash development.
Can someone please explain what I am doing wrong?
For one thing, you're using classes of the name Camera from two different namespaces without disambiguating between the two. You'll probably also have to import other packages to support API versions of Camera and Video though (flash.media.Camera and flash.media.Video), but I'm not completely convinced this won't be done implicitly, especially not knowing the environment you're using.
Another thing you have to watch out for though, as far as realtime errors go, is when it takes the browser a few seconds to actually get the camera - just keep trying to grab it for at least a few seconds until it returns something other than null.
Found somethng that actually works, and will be adapting it for my needs:
package
{
import flash.display.Sprite;
import flash.events.NetStatusEvent;
import flash.net.NetConnection;
import flash.net.NetStream;
import flash.media.Camera;
import flash.media.Microphone;
import flash.media.Video;
public class FlashVideo extends Sprite
{
private var nc:NetConnection;
private var good:Boolean;
private var rtmpNow:String;
private var nsIn:NetStream;
private var nsOut:NetStream;
private var cam:Camera;
private var mic:Microphone;
private var vidLocal:Video;
private var vidStream:Video;
public function FlashVideo()
{
trace("Hello testing");
rtmpNow = "rtmp://localhost/LiveStreams";
nc=new NetConnection();
nc.connect(rtmpNow);
nc.addEventListener(NetStatusEvent.NET_STATUS,checkCon);
setCam();
setMic();
setVideo();
}
private function checkCon(e:NetStatusEvent):void
{
good = e.info.code == "NetConnection.Connect.Success";
if (good)
{
nsOut = new NetStream(nc);
nsOut.attachAudio(mic);
nsOut.attachCamera(cam);
nsOut.publish("left","live");
nsIn = new NetStream(nc);
nsIn.play("right");
vidStream.attachNetStream(nsIn);
}
}
private function setCam()
{
cam = Camera.getCamera();
cam.setKeyFrameInterval(9);
cam.setMode(640,400,30);
cam.setQuality(0,95);
}
private function setMic()
{
mic = Microphone.getMicrophone();
mic.gain = 85;
mic.rate = 11;
mic.setSilenceLevel(15,2000);
}
private function setVideo()
{
vidLocal = new Video(cam.width,cam.height);
addChild(vidLocal);
vidLocal.x = 15;
vidLocal.y = 30;
vidLocal.attachCamera(cam);
vidStream = new Video(cam.width,cam.height);
addChild(vidStream);
vidStream.x=(vidLocal.x+ cam.width +10);
vidStream.y = vidLocal.y;
}
}
}

play flv using netStream appendBytes

I know that there are many ways to play an FLV file but considering my project requirements, I need to play the flv using URLStream and NetStream
here's the complete sample code that I'm doing my tests on:
package
{
import flash.display.Sprite;
import flash.events.Event;
import flash.events.NetStatusEvent;
import flash.events.ProgressEvent;
import flash.utils.ByteArray;
import flash.net.URLRequest;
import flash.net.URLLoader;
import flash.net.URLLoaderDataFormat;
import flash.net.NetStreamAppendBytesAction;
import flash.net.NetConnection;
import flash.net.NetStream;
import flash.media.Video;
import flash.net.URLStream;
/**

* #author Hadi Tavakoli
*/
public class Main extends Sprite
{
private var netConnection:NetConnection;
private var netStream:NetStream;
private var ul:URLStream;
private var video:Video;
private var bytes:ByteArray = new ByteArray();
private var _isSeek:Boolean = false;
public function Main():void
{
if (stage) init();
else addEventListener(Event.ADDED_TO_STAGE, init);
}
private function init(e:Event = null):void
{
removeEventListener(Event.ADDED_TO_STAGE, init);
// entry point
video = new Video();
addChild(video);
netConnection = new NetConnection();
netConnection.addEventListener(NetStatusEvent.NET_STATUS, netConnectionStatusHandler);
netConnection.connect(null);
}
private function netConnectionStatusHandler(ev:NetStatusEvent):void
{
switch(ev.info.code)
{
case 'NetConnection.Connect.Success':
ul = new URLStream();
ul.addEventListener(ProgressEvent.PROGRESS, onProgress);
ul.load(new URLRequest('01.flv'));
break;
}
}
private function onProgress(e:ProgressEvent):void
{
ul.readBytes(bytes, bytes.length);
if (!netStream)
{
netStream = new NetStream(netConnection);
netStream.client = { };
video.attachNetStream(netStream);
netStream.play(null);
trace("BEGIN")
netStream.appendBytesAction(NetStreamAppendBytesAction.RESET_BEGIN);
}
else
{
if (!_isSeek)
{
trace("SEEK")
netStream.appendBytesAction(NetStreamAppendBytesAction.RESET_SEEK);
_isSeek = true;
}
}
if (bytes.length == e.bytesTotal)
{
trace("END")
netStream.appendBytesAction(NetStreamAppendBytesAction.END_SEQUENCE);
}
netStream.appendBytes(bytes);
trace("-")
}
}
}
I'm not sure if I am using "appendBytes" method correctly? the video is shown but only a very few first frames will play and then the video stops!
in my eyes it seems all ok! do you have any advice on where my problem is?
I don't think you need the if (!_isSeek) block. It looks like you are pushing the bytes as you receive them in a sequential order and so there's never a seek. It looks like it will push the first set of bytes and then append a seek action and append the rest of the bytes. Try just removing that block and see if it works.
Otherwise I think it's ok.
in "ul.readBytes(bytes, bytes.length);" line, there is a bug i guess. It's never worked for me also. It always return full length (from 0 to the available bytes). So It have a huge memory leak. But if you are using flash player 11.4 or later, you can change it like this.
ul.position = bytes.length;
ul.readBytes(bytes);

Flash workers - sample application not working

I'm trying to get the hang of the AS3 workers, but there must be some elusive bit of understanding that just escapes me.
I've build a fairly simple PoC to see how it should work, but with no luck. When I run the "master" SWF, it seems to load the worker SWF fine and goes through everything without a hitch, except there's no response from the bloody worker.
I'm using Flash Builder 4.6 with FlexSDK 4.9.1, the PoC projects are built as ActionScript projects.
The worker file:
package
{
import flash.display.Sprite;
import flash.events.Event;
import flash.system.MessageChannel;
import flash.system.Worker;
public class WorkerPOC extends Sprite
{
private var wToM:MessageChannel;
private var mToW:MessageChannel;
public function WorkerPOC()
{
wToM = Worker.current.getSharedProperty("wToM") as MessageChannel;
mToW = Worker.current.getSharedProperty("mToW") as MessageChannel;
trace(mToW.receive());
wToM.send("Ready");
}
}
}
The master file:
package
{
import flash.display.Sprite;
import flash.events.Event;
import flash.net.URLLoader;
import flash.net.URLLoaderDataFormat;
import flash.net.URLRequest;
import flash.system.MessageChannel;
import flash.system.Worker;
import flash.system.WorkerDomain;
import flash.utils.ByteArray;
public class WorkerMaster extends Sprite
{
private var workerLoader:URLLoader;
private var workerData:ByteArray;
private var worker:Worker;
private var wToM:MessageChannel;
private var mToW:MessageChannel;
public function WorkerMaster()
{
workerLoader = new URLLoader();
workerLoader.dataFormat = URLLoaderDataFormat.BINARY;
addEventListener(Event.ADDED_TO_STAGE, onAdded);
}
private function onAdded(event:Event):void
{
removeEventListener(Event.ADDED_TO_STAGE, onAdded);
workerLoader.addEventListener(Event.COMPLETE, onHasWorker);
workerLoader.load(new URLRequest("workers/WorkerPOC.swf"));
}
private function onHasWorker(event:Event):void
{
workerData = workerLoader.data as ByteArray;
workerData.shareable = true;
worker = WorkerDomain.current.createWorker(workerData);
wToM = worker.createMessageChannel(Worker.current);
wToM.addEventListener(Event.CHANNEL_MESSAGE, onMessage);
wToM.addEventListener(Event.CHANNEL_STATE, onState);
mToW = Worker.current.createMessageChannel(worker);
worker.setSharedProperty("wToM",wToM);
worker.setSharedProperty("mToW",mToW);
worker.start();
mToW.send(123);
}
private function onState(event:Event):void
{
trace("Channel state: ", wToM.state);
}
private function onMessage(event:Event):void
{
trace(wToM.receive());
}
}
}
I've been working with workers as well. I had them working for a while then everything kinda just stopped, in the same way yours is not working.
Looks like the messagechannel is not sending the messages properly in debug in 11.7.
Not sure why it is happening, but try running your code without the debugger attached when the worker is created. When I do that it works fine...
Sounds strange, but have you applied
-swf-verion=XXX // XXX must be > 17
as a compiler argument? I am asking this, because I had a very similar problem :)

Flash Builder 4.6 Mobile Flex AS3: How to communicate with embedded SWF

I have a Flash Barcode scanner (camera) and want to use it in a mobile project to scan QR-Codes. It would be nice that it is possible to re-use this SWF and embedded it into a mobile Flex application. The SWF is made in Flash CS5.
So far, embedding (and add it to the stage and showing it) is successful but how do i communicate with the SWF? For example calling a function of it or by using events.
Here is a code snippet:
[Embed(source="../cam/cam.swf")]
private var cam:Class;
....
....
public const EVT_SNAPSHOT : String = "onSnapShot";
public var camera : Object;
public function onInit(e:Event) : void
{
this.camera = new cam();
this.camera.addEventListener(Event.ADDED_TO_STAGE, this.cameraInit );
this.stage.addChild( this.camera as DisplayObject );
}
private function cameraInit(e:Event):void
{
trace( 'Added to stage' );
this.stage.addEventListener( EVT_SNAPSHOT, this.cameraDoScan ); // does not bind?
trace( this.camera.hasOwnProperty('getAppInfo') ); // shows 'false'
}
private function cameraDoScan(e:MouseEvent):void
{
trace('MouseClick!');
}
Does anyone know to communicate with this 'thing'?
The most functional way to use external swf module is to load it into current ApplicationDomain, so you will have access to all classes contained in this loaded swf:
package
{
import flash.display.DisplayObject;
import flash.display.Loader;
import flash.display.Sprite;
import flash.events.Event;
import flash.system.ApplicationDomain;
import flash.system.LoaderContext;
import flash.utils.ByteArray;
import flash.utils.getDefinitionByName;
public class astest extends Sprite
{
[Embed(source="/../assets/art.swf", mimeType="application/octet-stream")]
private static const art:Class;
public function astest()
{
var artBytes:ByteArray = new art() as ByteArray;
var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onArtLoaded);
loader.loadBytes(artBytes, new LoaderContext(false, ApplicationDomain.currentDomain));
}
protected function onArtLoaded(e:Event):void
{
var domain:ApplicationDomain = ApplicationDomain.currentDomain;
if(domain.hasDefinition("welcome_view"))
{
var moduleClass:Class = domain.getDefinition("welcome_view") as Class;
var module:Object = new moduleClass();
//module.moduleFunction();
addChild(module as DisplayObject);
}else
{
trace("loaded swf hasn't class 'welcome_view'");
}
}
}
}

as3 Adobe Air access iPad device camera

Is there a way you can use as3 to access iPad's camera?
I mean start the Camera within the app itself
have ability take a shoot and save the image to byteArray and applying the image to the background or doing some manipulation
I have done some research most of them just showing how to access the android devices.
Thanks for any suggestion or help.
Yes, you can absolutely do this. The beauty of Flash is that the code to do it is the same that you would use on Android or a PC.
Literally, you can do this to connect the camera to a Video object:
var camera:Camera = Camera.getCamera();
var video=new Video();
video.attachCamera(camera);
this.addChild(video); // 'this' would be a Sprite or UIComponent, etc...
There's a lot more to do if you want to do something useful, but it's fairly straight forward once you get started :)
bluebill1049, I'm not certain from the thread if you got what you were looking for, but I did see your request for the whole class. I found the same information (that Jason Sturges posted in his answer) in this post.
take photo using Adobe Builder (flex) for iOS
Unlike his reply here, his reply to that post had had a link to a great tutorial on building a mobile app and it was from that tutorial that this code was lifted/quoted. It requires an event class (event.CameraEvent - only a few lines) that's contained in that project/tutorial so it's important to be able to go back to the source, as it were. That source is located here:
http://devgirl.org/files/RIAUnleashed/
My thanks to Jason. Just so you don't have to dig, here's the event class that's missing from the quote:
package events
{
import flash.events.Event;
import flash.filesystem.File;
public class CameraEvent extends Event
{
public static const FILE_READY:String = "fileReady";
public var file:File;
public function CameraEvent(type:String, file:File=null, bubbles:Boolean = true, cancelable:Boolean = true)
{
super(type, bubbles, cancelable);
this.file = file;
}
}
}
Hope that helps!
Using the loader is not the only way to access the image bytes on iOS. It turns out the data is already in JPEG format to begin with, so encoding it again is not necessary.
Just do a mediaPromise.open() to get at the bytes and save them directly instead.
XpenseIt example code offers this camera implementation:

return;
}
else
{
// Android we can just dispatch the event that it's complete
file = new File(mediaPromise.file.url);
dispatchEvent(new CameraEvent(CameraEvent.FILE_READY, file));
}

var stream:FileStream = new FileStream()
stream.open(file, FileMode.WRITE);
