I can't add name and image from Facebook contacts to SqLite, becouse adding is inside in loop and loader start when Event is Complete. Fllowing code adds data to the database, but in the name of the object is the last person out of the loop. Any thoughts? Thanks!
private var person:PersonVO;
protected function handleFriendsLoad(response:Object, fail:Object):void
{
if (fail) { return }
var friends:Array = response as Array;
var l:uint=friends.length;
for (var i:uint=0;i<l;i++) {
var friend:Object = friends[i];
FacebookDesktop.api('/'+friend.id, loadData);
}
}
private function loadData(object:Object, fail:Object):void
{
if (fail) { return; }
var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, imageToByteArray);
loader.load(new URLRequest(FacebookDesktop.getImageUrl(object.id, 'large')));
person = new PersonVO()
person.name = object.first_name;
}
private function imageToByteArray(event:Event):void
{
var wczytaj:Loader = (event.target as LoaderInfo).loader;
var image:Bitmap = Bitmap(wczytaj.content);
var encoderJpeg:JPEGEncoder = new JPEGEncoder();
var byteArray:ByteArray = encoderJpeg.encode(image.bitmapData);
person.image= byteArray;
insert(person);
}
private function insert(person:PersonVO):void
{
dbStatement.text = "INSERT INTO person (name,image) values(:name,:jpeg)";
dbStatement.parameters[":name"] = person.name;
dbStatement.parameters[":jpeg"] = person.image;
dbStatement.execute();
}
Extend Loader class functionality:
dynamic class DynamicLoader extends Loader{}
Then store whatever you want in instances of DynamicLoader:
private function loadData(object:Object, fail:Object):void
{
if (fail) { return; }
var person:PersonVO = new PersonVO();
person.name = object.first_name;
var loader:DynamicLoader = new DynamicLoader();
loader.person = person;
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, imageToByteArray);
loader.load(new URLRequest(FacebookDesktop.getImageUrl(object.id, 'large')));
}
private function imageToByteArray(event:Event):void
{
var wczytaj:DynamicLoader = (event.target as LoaderInfo).loader as DynamicLoader;
var image:Bitmap = Bitmap(wczytaj.content);
var encoderJpeg:JPEGEncoder = new JPEGEncoder();
var byteArray:ByteArray = encoderJpeg.encode(image.bitmapData);
var person:PersonVO = wczytaj.person;
person.image= byteArray;
insert(person);
}
I have not used private var person:PersonVO;. So if you are not using it in the other methods of your class, you could remove it completely.

I want to have embed video in flash game and have it looped. Is there a way to do it? As my code or more likely .seek or .resume dont give any effect? Am I using wrong commands or?
[Embed(source = "fast.flv", mimeType = "application/octet-stream")]
public var bytes:Class;
public var vidNS:NetStream
public var video:Video = new Video(1280, 720);
public var ns:NetStream;
public function Main() {
Doit();
}
private function Doit():void{
addChild(video);
var vidNC:NetConnection = new NetConnection(); vidNC.connect(null);
vidNS = new NetStream(vidNC);
var metaListener :Object = new Object(); metaListener = { onMetaData: process_Metadata };
vidNS.client = metaListener;
vidNS.addEventListener(NetStatusEvent.NET_STATUS, videoStatusHandler);
vidNS.play(null);
var file:ByteArray = new bytes();
vidNS.appendBytes(file);
video.attachNetStream(vidNS);
}
function process_Metadata (in_Data :Object):void
{
trace("duration is : " + in_Data.duration );
}
function videoStatusHandler (event:NetStatusEvent):void
{
if (event.info.code == "NetStream.Buffer.Empty")
{
trace('loop')
vidNS.seek(0); vidNS.resume();
}
}
You can loop by just simply re-feeding the bytes to the decoder (NetStream)
It's possible that you also need to involve the option RESET_BEGIN:
yourNS.appendBytesAction( NetStreamAppendBytesAction.RESET_BEGIN );
Try setting your code like below:
[Embed(source = "fast.flv", mimeType = "application/octet-stream")]
public var bytes:Class;
public var vidNS:NetStream;
public var video:Video = new Video(1280, 720);
public var ns:NetStream;
//# declare these vars outside of a function for global access
public var file:ByteArray = new bytes();
public var vidNC:NetConnection;
public var metaListener :Object;
public function Main()
{
Doit();
}
private function Doit():void
{
addChild(video);
vidNC = new NetConnection(); vidNC.connect(null);
vidNS = new NetStream(vidNC);
metaListener new Object(); metaListener = { onMetaData: process_Metadata };
vidNS.client = metaListener;
vidNS.addEventListener(NetStatusEvent.NET_STATUS, videoStatusHandler);
vidNS.play(null);
//var file:ByteArray = new bytes();
vidNS.appendBytes(file); //# feed video bytes to decoder
video.attachNetStream(vidNS);
}
function process_Metadata (in_Data :Object):void
{
trace("duration is : " + in_Data.duration );
}
function videoStatusHandler (event:NetStatusEvent):void
{
if (event.info.code == "NetStream.Buffer.Empty")
{
trace('now doing: looping...')
//# there is no timeline ".seek" in appendBytes mode, use ".seek" to clear the buffer for a new re-feed
vidNS.seek(0); //clears the current buffer (video data is removed)
vidNS.appendBytesAction( NetStreamAppendBytesAction.RESET_BEGIN ); //re-set timestamps for decoder
vidNS.appendBytes(file); //re-feed video bytes to decoder
}
}
So Thanks to VC. One i ended up with this code:
[Embed(source="1.flv", mimeType="application/octet-stream")]
public var bytes:Class;
public var vidNS:NetStream;
public var video:Video = new Video(1280, 720);
public var file:ByteArray = new bytes();
public var vidNC:NetConnection;
public var metaListener :Object;
public function Main()
{
Doit();
}
private function Doit():void
{
addChild(video);
vidNC = new NetConnection(); vidNC.connect(null);
vidNS = new NetStream(vidNC);
metaListener new Object(); metaListener = { onMetaData: process_Metadata };
vidNS.client = metaListener;
vidNS.play(null);
vidNS.appendBytes(file);
video.attachNetStream(vidNS);
}
function process_Metadata (in_Data :Object):void
{
trace("loop ");
vidNS.appendBytesAction(NetStreamAppendBytesAction.RESET_BEGIN);
vidNS.appendBytes(file);
}
Its working like it should, but i'm not sure if thats the right way of doing it ^^.
My flash project has specific task to show the dynamic gallery items based on an XML list and there is a download option available for each gallery item.
For this I made a movieclip (imageTile) with a Thumbnail, Title, ProgressBar & ProgressText as shown below.
I have two classes named Main.as and FileRef.as
Main.as
var tileMap:Dictionary = new Dictionary();
public var tile:ImageTile;
addChild(wall);
wallWidth = wall.width;
wallHeight = wall.height;
var columns:Number;
var my_x:Number;
var my_y:Number;
var my_thumb_width:Number;
var my_thumb_height:Number;
var images:XMLList;
var total:Number;
var swipe:Number = 0;
var myXMLLoader:URLLoader = new URLLoader();
myXMLLoader.load(new URLRequest("gallery.xml"));
myXMLLoader.addEventListener(Event.COMPLETE, processXML);
function processXML(e:Event):void {
myXML = new XML(e.target.data);
images = myXML.IMAGE;
total = images.length();
myXMLLoader.removeEventListener(Event.COMPLETE, processXML);
myXMLLoader = null;
var loader:Loader;
for (var i:uint = 0; i < total; i++) {
tile = new ImageTile();
wall.addChild(tile);
tile.x = i % 3 * 400 + 180;
tile.y = Math.floor(i / 3) * 650 + 250;
var imageName:String = images[i].#FULL;
path = images[i].#Path;
var title:String = images[i].#Title;
**var caption:TextField = tile.getChildByName("caption_tf") as TextField;**
caption.text = title;
tile.addEventListener(MouseEvent.CLICK, onTileClick(path));
loader = new Loader();
loader.load(new URLRequest("images/" + imageName));
tileMap[loader] = tile;
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onImageLoad);
}
//trace(myXML);
}
var tileMap:Dictionary = new Dictionary();
function onImageLoad(e:Event):void {
var loader:Loader = e.target.loader;
var tile:ImageTile = tileMap[loader] as ImageTile;
var image:Bitmap = loader.content as Bitmap;
image.x = -100;
image.y = -100;
image.width=366;
image.height=418;
var textField:DisplayObject = tile.getChildByName("caption_tf");
var textFieldDepth:int = tile.getChildIndex(textField);
tile.addChildAt(image, textFieldDepth);
tileMap[loader] = null;
image.smoothing = true;
}
function onTileClick(url:String):Function {
return function(me:MouseEvent):void {
path = url;
var download:FileRef = new FileRef();
download.downloadFile(path);
}
FileRef.as code
public var mc_loaded : MovieClip = Main.gameInstance.tile.getChildByName("mc_loaded") as MovieClip,
mc_progress : MovieClip = Main.gameInstance.tile.getChildByName("mc_progress") as MovieClip,
txt_prog : TextField = Main.gameInstance.tile.getChildByName("txt_prog") as TextField;
public function downloadFile(url:String) : void
{
/// Download the gallery item codes using url
}
public function progressHandler( event : ProgressEvent ) : void
{
//mc_loaded.scaleX = (event.bytesLoaded / event.bytesTotal) ;
}
public function completeHandler( event : Event ) : void
{
//reset progress bar after download is finished
mc_loaded.scaleX = 0; // I want to use the imageTile element
txt_prog.text = "download finished";
}
public function OnZipComplete(evt:flash.events.Event):void
{
txt_prog.text = "download finished";
}
The download works fine, but I can not get the progress bar and progress text for every tile created.
I got the answer
Remove onTileClick(url:String) function from Main.as
Main.as
function processXML(e:Event):void {
//// Codes /////
//// Codes /////
var download:FileRefTut = new FileRefTut();
tile.addEventListener(MouseEvent.CLICK, download.downloadFile(path));
}
FileRef.as
public var txt_prog:TextField, mc_loaded:MovieClip;
public function downloadFile(url:String):Function {
return function(me:MouseEvent):void {
var tile:ImageTile = me.currentTarget as ImageTile;
txt_prog = tile.getChildByName("txt_prog") as TextField;
mc_loaded = tile.getChildByName("mc_loaded") as MovieClip;
}
public function progressHandler( event : ProgressEvent ) : void
{
mc_loaded.scaleX = (event.bytesLoaded / event.bytesTotal) ;
}
public function completeHandler( event : Event ) : void
{
//reset progress bar after download is finished
mc_loaded.scaleX = 0; // I want to use the imageTile element
txt_prog.text = "download finished";
}
public function OnZipComplete(evt:flash.events.Event):void
{
txt_prog.text = "download finished";
}
I have this code in my MXML project, I want to get dynamic Stream connection for different and dynamic usernames.
private var inStream:NetStream;
private function listenStream(user:String):void
{
this["inStream"+user] = new NetStream(connection);
this["inStream"+user].play(user);
}
private function closeStream(user:String):void
{
//clear stream listener
this["inStream"+user].close();
}
But this code is not worked, How can i build dynamic object names in ActionScript3?
Thanks alot
Try Dictionary
import flash.utils.Dictionary
private var streamDict:Dictionary = new Dictionary();
private function listenStream(user:String):void
{
var key:String = getKey(user);
var lastStream:NetStream = streamDict[key] as NetStream;
if (lastStream)
{
//close the last stream or do sth else
}
else
{
streamDict[key] = new NetStream(connection);
streamDict[key].play(user);
}
}
private function closeStream(user:String):void
{
var key:String = getKey(user);
//clear stream listener
var stream:NetStream = streamDict[key] as NetStream ;
if (stream)
{
stream.close();
}
//delete the stream
streamDict[key] = null;
delete streamDict[key];
}
private function getKey(user:String):String
{
return "inStream" + user;
}
I have searched on google en different pages i found the problem but not the solution.
I have a class i made and that class is called WebServiceController:
public class WebServiceController
{
private var url:String;
private var post:Object=new Object();
private var loader:URLLoader = new URLLoader();
private var postVariable:String="";
private var getVariable:String="";
private var Geladen:Boolean=false;
public function WebServiceController()
{
}
public function postUrlData(u:String,p:Object):String
{
url=u;
post=p;
var urlReq:URLRequest = new URLRequest (url);
var i:int=0;
for(var key:String in post)
{
//trace(key +" = " + post[key]);
if(i==0)
{
// urlVars.key = post[key];
postVariable=postVariable+""+key+"="+post[key];
}
else
{
//urlVars.key = post[key];
postVariable=postVariable+"&"+key+"="+post[key];
}
i++;
}
//trace(postVariable);
var urlVars:URLVariables = new URLVariables(postVariable);
//trace(urlVars);
// Add the variables to the URLRequest
urlReq.data = urlVars;
urlReq.method = URLRequestMethod.POST;
// Add the URLRequest data to a new Loader
//loader.load(urlReq);
// Set a listener function to run when completed
loader.addEventListener(Event.COMPLETE, onLoaderComplete);
// Set the loader format to variables and post to the PHP
loader.dataFormat = URLLoaderDataFormat.VARIABLES;
loader.load(urlReq);
function onLoaderComplete(event:Event):void
{
return loader.data;
}
}
Now from my movieclip i call the next function but it says undefined:
var wb:WebServiceController = new WebServiceController();
trace(wb.postUrlData(url,post));
I dont know how to solve this. I tried different things but it keeps saying undefined.
The URLLoader.load call is executed asynchronously so the data has not been returned when you attempt to trace it out in the class that instantiates your WebServiceController class.
To access the data in the parent class, your best bet is probably to dispatch an event from the WebServiceController class when the data has loaded and catch it in the parent class.
WebServiceController:
public function postUrlData(u:String, p:Object):void
{
url=u;
post=p;
var urlReq:URLRequest = new URLRequest (url);
var i:int=0;
for(var key:String in post)
{
//trace(key +" = " + post[key]);
if(i==0)
{
// urlVars.key = post[key];
postVariable=postVariable+""+key+"="+post[key];
}
else
{
//urlVars.key = post[key];
postVariable=postVariable+"&"+key+"="+post[key];
}
i++;
}
//trace(postVariable);
var urlVars:URLVariables = new URLVariables(postVariable);
//trace(urlVars);
// Add the variables to the URLRequest
urlReq.data = urlVars;
urlReq.method = URLRequestMethod.POST;
// Add the URLRequest data to a new Loader
//loader.load(urlReq);
// Set a listener function to run when completed
loader.addEventListener(Event.COMPLETE, onLoaderComplete);
// Set the loader format to variables and post to the PHP
loader.dataFormat = URLLoaderDataFormat.VARIABLES;
loader.load(urlReq);
}
private function onLoaderComplete(event:Event):void
{
// We can pass the event on like this
dispatchEvent(event);
}
Parent class:
public function initWebServiceController():void
{
var wb:WebServiceController = new WebServiceController();
wb.addEventListener(Event.COMPLETE, onWebServiceControllerDataLoaded);
wb.postUrlData(url, post);
}
private function onWebServiceControllerDataLoaded(event:Event):void
{
// The event target is the URLLoader instance. We can
// access the loaded data via its data property
trace(URLLoader(event.target).data);
}
I develop my own way of doing this simple task. However, I'm now wondering if there is a better way to do it.
The buttons:
var menuBtnEscrit:MovieClip = new MovieClip();
var mbe:btnEscritorio = new btnEscritorio();
menuBtnEscrit.addChild(mbe);
menuBtnEscrit.val = "escrit";
menuBtnEscrit.x = 80;
menuBtnEscrit.addEventListener(MouseEvent.CLICK, novoCont);
dMenu.addChild(menuBtnEscrit);
var menuBtnPublic:MovieClip = new MovieClip();
var mbp:btnPublic = new btnPublic();
menuBtnPublic.addChild(mbp);
menuBtnPublic.val = "public";
menuBtnPublic.x = 244;
menuBtnPublic.addEventListener(MouseEvent.CLICK, novoCont);
dMenu.addChild(menuBtnPublic);
And I can keep going, or create buttons trough some algorithm, and put more properties and take advantage of a MovieClip.
The handler:
private function novoCont(e=null){
if(e!=null) selecCont = new String(e.target.parent.val);
clearDisplay(dSubMenu);
clearDisplay(dConteudo);
var func:String = "cont_"+selecCont;
this[func]();
}
As you can see, there is some common task for all buttons.
If I click the first button, it will call cont_escrit() function. This mechanics works, but it is the best practice? Is there a way of optimize it?
public class BaseButton extends Button {
private var _func:Function;
public function get handler():Function {
return _func;
}
public function set handler(value:Function):void {
_func = value;
}
}
So hero you can create mbe like this
mbe = new BaseButton ();
mbe.hanler = cont_escrit;
The event hanler would be
private function novoCont(e=null){
if(e!=null) {
var selecContent:BaseButton = e.targe as BaseButton ;
var handler:Function = selecContent.handler;
handler();
}
}
Here is an example.
var menuBtnEscrit:MovieClip = new MovieClip();
var mbe:btnEscritorio = new btnEscritorio();
menuBtnEscrit.addChild(mbe);
//menuBtnEscrit.val = "escrit";
menuBtnEscrit.func = this.cont_escrit;
menuBtnEscrit.x = 80;
menuBtnEscrit.addEventListener(MouseEvent.CLICK, novoCont);
private function novoCont(e=null){
if(e!=null) {
var mc:MovieClip = e.target as MovieClip;
var func:Function = mc.func;
func();
}
clearDisplay(dSubMenu);
clearDisplay(dConteudo);
}
