I have built a music community website, obviously members can sign up for an account, and upload mp3 files to their accounts.Once registration is complete, the php script creates a folder in the members directory on my server with their unique id, then when they go and upload an mp3, it uploads it to their folder and automatically creates a playlist.xml file for the song(s) I have a prebuilt flash mp3 player that I got from developphp.com, his as3 code calls for a static directory for the audio and xml, now since the flash player will live in the root, and the xml and audio will live in the members/$id folders, I am told to use flashvars and loaderinfo.parameters to do what I need, and that is to load the xml and mp3 files into the player for the profile that is being viewed at that moment, so lets look at what I've put into the html object and embed.
lets use profile #7
<param name="movie" value="flplayer.swf?<?php print"$id/playlist.xml" ?>"> <embed src="flplayer.swf?<?php print "$id/playlist.xml" ?>"> (please tell me if I have done this incorrectly)
now if we go to the profile.php?id=7 page, thius is what the page source looks like:
now here is where I am stuck, as I said the flash mp3 player urlLoader and URLRequest, and I have been searching for days to figure out what I am supposed to do to get the player to pick up on the flash vars, here is the top part of the as3 code where it calls for the mp3 and the xml.
stop(); var myFormat:TextFormat = new TextFormat(); myFormat.color = "0xFFFFFF"; list.setRendererStyle("textFormat", myFormat);
That is part of the source in the LoaderExample.swf. And all I get is a "Parameter text must be non-null" error. I've alternatively tried the FlashVars method using additional <param> and <object> tags but i get the same error. What is going on with Actionscript 3? is this a bug? What am I doing wrong? Do the 5 or 6 tutorials i've read leave some important detail out ?
Flash gives access to query-string parameters via calling loaderInfo.parameters() method.And I couldn't delete the field on the object. IS it possible to delete some fields in the object? how can I do this?
I have a problem with Flex module. I want to access url variables by this.loaderInfo.url, i call a function in createionComplete handler of module and sometimes it works and sometimes it doesn't. (Can't access... null). Any suggestions?
This function is called in creationComplete handler of module. And although it throws error window, the alert with url shows and contains url of module.
private function checkModuleUrl():void { var url:String = this.loaderInfo.url; Alert.show(url); }
I have a class that loads a handful of external swfs, and a preloader class to handle them all as a single object.I was having some strange problems with the loading process and tried tracing the urls to see which file was bugging. For my surprise, almost all loaderInfo objects reported theirs url as null.With a bit of testing I came to the conclusion that they only report some url when the file is almost completely loaded. The docs say something about "possibly wrong urls" before progress events, but that would be in cases where redirect happen, and everything here is local with simulate download option. Also, "event.target.url" inside the very progress event handler reports null unless the target's loading is almost done. Unfortunately I don't have any piece of code with less than a hundred lines to show. But is there any undocumented behavior, known bug or common coding error that generates such situation?
I've coded this small snippet to show what I'm not understanding:

Shouldn't I be able to read loaderInfo inside the creationComplete handler? I'm trying to pass a string from the html to my flash component, that's why I have to get loaderInfo working.
I am changing the flashvars variables v1=value&v2=value ect then after the flash movie runs I am changing the variables externally by javascript, so far so good.when flash first loads it reads the vars correctly.when I try to read them ( after the change ) it keeps reading the old values.[code]everything works except I cannot seem to read the changed FlashVars.
I am trying to use FlashVars to pass a parameter that will determine which graphic to load into my movie. The test actionscript code uses a dynamic text field called dText and is coded as follows (testing the FlashVars by passing them to a dynamic text field):
function loaderComplete(myEvent:Event){ var flashVars=this.loaderInfo.parameters; dText.text=flashVars.userName; } this.loaderInfo.addEventListener(Event.COMPLETE, loaderComplete);
In my html code I am adding: <PARAM NAME=FlashVars VALUE="userName=SamG" /> FlashVars="userName=SamG" // added to the embed tag
trying to cut text field to single letters and then do some animations on each letter. But, how do I know where to place (position) the letters? I tried using getCharBoundaries but once it reaches 3rd line, it keeps returning null values. Anybody knows why that happens
I've got an object inside an object. The child object basically loads a variable from SQL into one of it's own public variables. The SQL works 100%, because it traces out correctly.Now I've wrote a function from the child.as
Code: public get_var() : String { return var_yes_friggin_work;[code].....;
Of course the files arn't called Parent.as and Child.as I've just had to rename them because our work is monitored though checking the internet and I can't delete this form.The FilePathOriginal doesn't output anything unless the string is manually set from the child, does anyone know where I'm going wrong here? (I can't upload all my code because of the monoriting process)
how can i get values of parameters name1 and name2 in embed tag as following HTML code using AS 3.0 but not using FlashVars (because of i need to suite with all embed code of older version AS 2.0)
I have an ArrayCollection with following structure (when viewed in debug mode): [0] - [0] -- src - [1] -- src src is the path to an image.
I need to get all of the src's out of the arraycollection. However because of the first (unnamed) node I can't take them in. I've tried ArrayCollection[0].children and save the result in another ArrayCollection, however the new ArrayCollection has 2 Objects in it but no 'src'. There are just 2 null objects firstArrayCollection is filled with the data as described above. secondArrayCollection.addItem(firstArrayCollection[0].children);
When viewing the content of secondArrayCollection i see following structure (and data): [0] null [1] null
I'm trying to implement Gravity from GraniteDS. I did everything like in example from GraniteDS website, but when I'm trying to get gravity from servlet context, ravityManager.getGravity returns null. Here is the code: Gravity gravity = GravityManager.getGravity(contextManager.getServletContext());What can be the reason of this error?
I have created a Composite Pattern type structure, with TreeNodes and TreeLeaf Objects.I works fine, except when I seach in the treestructure for TreeNodes and TreeLeafs in a resurve function with a loop, the function returns null - even on a successfull match.
public function traceTree(inComponent : TreeComponent = null) : TreeComponent{ var parentComponent : TreeComponent = inComponent; if(inComponent == null){
ActionScript Code: public function draw():Card{ return deck.pop(); //deck = array of Card } Does not work. Firstly it runs an error which says "cannot convert [] to Card"... Shouldn't it pop() return just ONE element?
Then I correct like this ActionScript Code: public function draw():Card{ return deck.pop() as Card; //deck = array of Card }
And now I get no errors but the function returns null.... why? If I try this: ActionScript Code: public function draw():void{ trace(deck.pop()); //deck = array of Card } It prints [Object Card] which is how it should be ....
I'm making a list of alarms to pick from. I've googled for answers the past two days but I cannot figure out what my problem is with this batch of code.
I've got 7 items in the menu and the dropdown works good as long as you do not select the item that is already displayed in the menu. You can select another item and then reselect the original item, but I get error "Cannot access a property or method of a null object reference." from
I have a small issue, which is important for my project though. Namely my global var returns null when I need it. I have a global var class: Code: package { public class Global { public static var premiseGlobalName:String = new String(); }}
In another class I'm setting this var like so: Code: public function onButtonRollOver (event:MouseEvent):void { Global.premiseGlobalName = "My home"; this.addChild(premiseMenu); }
The second line in the method calls another class to the stage which uses the global var. I trace the global var: Code: public function initPremiseMenu():void { trace("GLOBAL: " + Global.premiseGlobalName); } But it returns an empty value.
I want to use the global var in a textfield like so: Code: premiseTip.text = Global.premiseGlobalName;
private function getFriends(thisSession:Facebook):void { getFr = new GetFriends(); var thisCall:FacebookCall; thisCall = thisSession.post(getFr); [Code] .....
I have an app where I am looking to make the enter key act like a tab key. I can easily capture the keypress event and setFocus to a textinput field. The problem is figuring out which textinput field to give focus to. I have this code
trace(this.window.focusManager); //returns TheWindow86.focusManager trace(this.window.focusManager.getNextFocusManagerComponent()); //returns null //This is what I was hoping would work this.window.focusManager.getNextFocusManagerComponent().setFocus();
The code is in a controller class and "this.window" references an instance of a nativeWindow mxml file "TheWindow.mxml". The first trace works as expected, but the second one gives null.
I am trying to create a custom object in AS3 to pass information to and from a server, which in this case will be Red5. In the below screenshots you will see that I am able to send a request for an object from as3, and receive it successfully from the java server. However, when I try to cast the received object to my defined objectType using 'as', it takes the value of null. It is my understanding that that when using "as" you're checking to see if your variable is a member of the specified data type. If the variable is not, then null will be returned.
This screenshot illustrates that I am have successfully received my object 'o' from red5 and I am just about to cast it to the (supposedly) identical datatype testObject of LobbyData:
I'm starting a facebook app using iframe method.I am using flex and so far I am able to connect to fb (login and out). Now I am trying to retrieve current logged in user name. In the document I see this function is what I need. Facebook.getSession().A tutorial in adobe site uses desktop api and it works for desktop (AIR app) but not for web app. (yes, i fixed Facebook.getSession() instead of FacebookDesktop.getSession(); Also, I am able to see the uid but not the user. User returns null. uid is a string and user is an object. But on the desktop app,FacebookDesktop.getSession().user.name returns the name perfectly. but on the web, it does not.
I'm currently working on a Flash application that has a sibling AIR equivalent. From inside the Flash application I would like to install the sibling AIR App. Adobe has provided an air.swf (which is also used in the Badge sample) to aid us with the install. I've managed to mimic the behavior of the Badge app butgetApplicationVersion always returns null. Note that I do not have a publisherId. Here's the documentation provided by Adobe: Installing and running an AIR applications from a web page
Air application XML: < id >MyAirApplication< /id > ...
I did a separate levelData class to be able to flexibly add levels. I was happy with it until my supervisor ordered me to convert my levelData into XML. I did an XML version of the levelData's data (question, answers, correct answer...). I used the old class and converted it so that it fetches the XML.
All seems well, I did traces of my answers array and it printed nicely...
But the headache started when I tried this.
// This code appears in a different class with // currentLvl:LevelData initialized in the constructor. quizHolder.ansA.ansHud.text = currentLvl.choices[1];
Adobe page for LoaderInfo states: The two sources of parameters are: the query string in the URL of the main SWF file, and the value of the FlashVars HTML parameter (this affects only the main SWF file). We would like to accept only FlashVars parameters and ignore the ones passed in as parts of Query String.
