i use LocalConnection between two swf in the same page.
What i'm trying to do is to use a String sent from one swf to the other, as variable into my URLRequest...
So i can trace "myVar" into the function chemin, but i didn't find how to use it into URLRequest
thank's for your help
swf that receive the var :
var lc:LocalConnection=new LocalConnection();
lc.client=this;
lc.connect("callBig");
function chemin(myVar:String){
trace(myVar)
}
var chargementXML:URLLoader = new URLLoader();
var fichier:URLRequest = new URLRequest(myVar);
Some references to help you out.
URLRequest.data: http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/net/URLRequest.html?filter_flex=4.1&filter_flashplayer=10.2&filter_air=2.6#data
URLVariables: http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/net/URLVariables.html
So, if you want to pass some variables in your request, you do the following:
Create new URLVariables() object
Assign it's reference to URLRequest.data field.
var fichier:URLRequest = new URLRequest();
var urlVars:URLVariables = new URLVariables();
urlVars["myVarName"] = myVar;
fichier.data = urlVars;
This way your server side app will recieve a variable myVarName with value of myVar.
var lc:LocalConnection=new LocalConnection();
lc.client=this;
lc.connect("callBig");
var receivedVar:String = "";
// somewhere else
function chemin(myVar:String){
receivedVar = myVar;
}
// later
var chargementXML:URLLoader = new URLLoader();
var vars:URLVariables = new URLVariables();
vars.myVar = receivedVar;
chargementXML.data = vars;
var fichier:URLRequest = new URLRequest(myVar);

I have a game, I want to write score in my database when the game is over. This is the urlloader function:
public function gameFinished(){
var urlLoader:URLLoader = new URLLoader();
var req:URLRequest = new URLRequest("/../../sendScoreUnit4.php");
var requestVars:URLVariables = new URLVariables();
requestVars.score = total_score_hard;
req.data = requestVars.score;
req.method = URLRequestMethod.POST;
urlLoader.load(req);
}
My sendScoreUnit4.php file tries to get the score like so :
$score = (int)$_GET['score'];
but when I echo it I get 0 every time.
Any help would be appreciated.
I have an problem to convert AS3 to AS2
Here is my AS3 code
submit.addEventListener("mouseDown", sendData);
function sendData(evt:Event)
{
//for those using PHP
var students:URLRequest = new URLRequest("http://localhost/phpflash/new_student.php");
students.method = URLRequestMethod.POST;
var posts:URLVariables = new URLVariables();
posts.Fullname = Fullname.text;
students.data = posts;
var loader:URLLoader = new URLLoader();
loader.dataFormat = URLLoaderDataFormat.VARIABLES;
loader.load(students);
}
Like #VC.One said, you must learn AS3, AS2 was dropped and actually Flash CC does not support it.
I do not code in AS2 since many, many years. So this code could contain some errors:
submit.onMouseDown = sendData;
function sendData():Void
{
var vars:LoadVars = new LoadVars();
vars.Fullname = Fullname.text;
var target:Object = new Object();
target.onLoad = function(){
trace("vars sended");
}
vars.sendAndLoad("http://localhost/phpflash/new_student.php", target, "POST");
}
How can I load external swf into bytearray with adobe flash AS3..
Here is my code..
var my_url1:URLRequest = new URLRequest("SWF/Lesson1.swf");
my_url1.method = URLRequestMethod.GET;
my_url1.contentType = "application/x-shockwave-flash";
var urlloader:URLLoader = new URLLoader(my_url1);
var myByteArray:ByteArray = new ByteArray();
urlloader.data = myByteArray;
It not works well. But it isn't give any error. How can I fix this problem?
You should listen for COMPLETE event and set the data format to BINARY:
var my_url1:URLRequest = new URLRequest("SWF/Lesson1.swf");
var urlloader:URLLoader = new URLLoader(my_url1);
urlloader.dataFormat = URLLoaderDataFormat.BINARY;
urlloader.addEventListener(Event.COMPLETE, function(event:Event):void
{
var myByteArray:ByteArray = URLLoader(event.target).data as ByteArray;
trace(myByteArray.length);
});
I have found Firebase, and it looks excellent for javascript / HTML5 usage.
But I was wondering if there is also an Actionscript API?
E.g
var myRootRef = new Firebase('https://myprojectname.firebaseIO-demo.com/');
myRootRef.set('Hello World!');
var dataRef = new Firebase('https://SampleChat.firebaseIO-demo.com/users/fred/name/first');
dataRef.on('value', function(snapshot) {
alert('fred’s first name is ' + snapshot.val());
});
So to set data and have listeners for updated data etc.
Thanks for any help

Doesn't look like there is an AS3 api available but the good news is that they have a rest api which is cross platform that you can write an AS3 wrapper around. (https://www.firebase.com/docs/rest-api.html) That is what I plan to do. I Want to use it with GameBuilder Studio.
If you are planning on embedding your application inside a web page (that you create) you could use an external javascript interface and communicate to firebase through that.
I'm planning on doing this myself to see how it turns out.
Connecting to Firebase using ActionScript 3 only requires the use of URLRequest and URLLoader. The following examples cover the 4 basic operations (CRUD).
To read data from an specific node from your Firebase database:
private function loadNews():void
{
var request:URLRequest = new URLRequest("https://<YOUR-PROJECT-ID>.firebaseio.com/<Node_to_read>.json");
var loader:URLLoader = new URLLoader();
loader.addEventListener(flash.events.Event.COMPLETE, newsLoaded);
loader.load(request);
}
private function newsLoaded(event:flash.events.Event):void
{
trace(event.currentTarget.data);
var rawData:Object = JSON.parse(event.currentTarget.data);
}
To insert data to a specific node:
private function saveEntry(title:String, description:String):void
{
var myObject:Object = new Object();
myObject.title = title;
myObject.description = description;
myObject.timestamp = new Date().getTime();
var request:URLRequest = new URLRequest("https://<YOUR-PROJECT-ID>.firebaseio.com/<Node_to_insert>.json");
request.data = JSON.stringify(myObject);
request.method = URLRequestMethod.POST;
var loader:URLLoader = new URLLoader();
loader.addEventListener(flash.events.Event.COMPLETE, entrySent);
loader.load(request);
}
private function entrySent(event:flash.events.Event):void
{
trace(event.currentTarget.data);
}
To delete a specific node:
private function deleteEntry():void
{
var header:URLRequestHeader = new URLRequestHeader("X-HTTP-Method-Override", "DELETE");
var request:URLRequest = new URLRequest("https://<YOUR-PROJECT-ID>.firebaseio.com/<Node_to_delete>.json");
request.method = URLRequestMethod.POST;
request.requestHeaders.push(header);
var loader:URLLoader = new URLLoader();
loader.addEventListener(flash.events.Event.COMPLETE, entryDeleted);
loader.load(request);
}
private function entryDeleted(event:flash.events.Event):void
{
trace(event.currentTarget.data);
}
To update/modify data to a specific node:
private function updateEntry(title:String, description:String):void
{
var header:URLRequestHeader = new URLRequestHeader("X-HTTP-Method-Override", "PATCH");
var myObject:Object = new Object();
myObject.title = title;
myObject.description = description;
var request:URLRequest = new URLRequest("https://<YOUR-PROJECT-ID>.firebaseio.com/journal/<Node_to_modify>.json");
request.data = JSON.stringify(myObject);
request.method = URLRequestMethod.POST;
request.requestHeaders.push(header);
var loader:URLLoader = new URLLoader();
loader.addEventListener(flash.events.Event.COMPLETE, entryUpdated);
loader.load(request);
}
private function entryUpdated(event:flash.events.Event):void
{
trace(event.currentTarget.data);
}
If you want further information I have written detailed Firebase REST guides and examples on how to use ActionScript 3 and Firebase.
Here is my code. What I m trying to achieve is to be able to capture an image from the the camera and upload it onto a media server but so far I have not been able to encode it succesfully .Can someone please point me in the right direction.
Here is the code
var imagePromise:MediaPromise = event.data;
imageLoader = new Loader();
imageLoader.contentLoaderInfo.addEventListener( Event.COMPLETE, asyncImageLoaded );
imageLoader.addEventListener( IOErrorEvent.IO_ERROR, cameraError );
imageLoader.loadFilePromise( imagePromise );
function asyncImageLoaded(event:Event):void
{
var destination:String = "upload.php";
var now:Date = new Date();
var fileName = "IMG" + now.fullYear + now.month + ".jpg";
var image:Bitmap = Bitmap(imageLoader.content);
var bitmapData:BitmapData = image.bitmapData;
var j = new JPGEncoder(80);
var bytes:ByteArray = j.encode(bitmapData);
}
This is the error I get when i try to encode the image
TypeError: Error #1009: Cannot access a property or method of a null object reference.
which line? 1009 means you're trying to access a variable of something that is NULL. I'm guessing in this case, it's probably the line:
var image:Bitmap = Bitmap(imageLoader.content);
Try adding this:
if (imageLoader.content is Bitmap) {
var image:Bitmap = Bitmap(imageLoader.content);
} else {
throw new Error("What the heck bob?");
}
If it's an error, I bet the content was not decoded properly (which could mean a mime-type that wasn't image/jpg)
Additionally, you could probably use the native jpeg encoder for speed: (flash 11 i believe?)
var byteArray:ByteArray = new ByteArray();
bitmapData.encode(new Rectangle(0,0,640,480), new flash.display.JPEGEncoderOptions(), byteArray);
