Actionscript 3 :: Serialization Format Common To Node.js?
Feb 22, 2011
The game is written in Flash, and I plan to develop the server in node.js because (a) it would be a cool project for learning node.js, and (b) it's fast, which is important for games.The server's architecture is based on messages sent between the server and client (sort of like Minecraft's server protocol). The message format I have so far is a byte (the packet type), two bytes (the message length) and that many bytes (the message data, which is a mapping of key-value pairs). Problem is, I really don't want to develop my own serialization format (because while I probably could, implementing it would be a pain compared to using an existing solution).Unfortunately, I am having problems finding a good candidate for the message data serialization format.
ActionScript's own remoting format might work, but I don't like it much.SON has support in node.js (obviously) and in ActionScript, but it's also textual and I would prefer binary for enhanced speed.MessagePack looked like a good candidate, but I can't find an ActionScript implementation. (There's one called as3-msgpack on Google Code, but I get weird errors and can't access it.)BSON has an ActionScript implementation, but no node.js support besides their MongoDB library (and I'm planning on using Redis).
Video format that play on any browser , with play/pause/stop buttons? i have the following code for .swf but i cant get any button to control. [code]...
s it possible to read a child of an XML file and format it as HTML in flash?I'm asking this because I want to include a description text as a child of a node and I need to know if there is a way to insert a line brake in the text...
I have an AdvancedDataGrid tree with a ArrayCollection as its dataprovider. Now, for instance, i drag a leaf from one node to another node. To catch the event I'm adding a Listener to dragComplete.
[Code]...
My Problem: I want to know the new node where the leaf was dropped. Actually i would have expected that in the event there is a property like dropParent. This is not the case.
I thought this was going to be easy! I would like to search an XML file for a particular data set i.e. set of nodes depending on a passed variable. However, storing a subset of my XML file via Code:var gallery = this.firstChild; and then searching 'gallery' as you would an array-using a for()-doesn't work since this.firstChild isn't returning an array
I am trying to set up a communication between a flash client and a C# server. I would like to know if Flash allows me to perform XML serialization in the way that C# does. This is because I would like to use the XMLserialization class in C# for passing of data. If this is not possible, what other methods are available for communication?

I have been trying to test my application to make sure that all the important classes can serialize/reload themselves properly (especially those which implement IExternalizable):
[Test] public function testMyObjectSerialization():void { var myobj:MyObject = new MyObject();[code]....
And I would like to be warned when I try to serialize a strongly-typed object which does not have a [RemoteClass] set (because that almost certainly represents a bug in my code).So, is there any way to configure the AMF serializer to give warnings?Also, it seems like this might be possible using services-config.xml... But the documentation seems to imply that services-config is channel-level, and I'd really like it if my unit tests could run without talking to the server (and I'm not using LCDS, so a bunch of the services-config wouldn't apply to me anyway).
I have an actionscript class that serializes and unserializes data compatible with php's serialization functions. I expanded it to support binary data but now the unserialization does not seem to work. For example, this data is not unserialized correctly:
Another observation on serialization:Make sure that you have registered ALL classes that may be written by the writeObject() method.By 'registering' I mean using the registerClassAlias() call.Most noticeably this goes for subclasses.For example, if I write an object to the streamwith
ActionScript Code: writeObject(question) and question is an object of class MCQuestion, which is a subclass of class Question,
What is serialization support like for the new Vector class? I have a Vector.<GameMove> which I'd like to serialize into a ByteArray. GameMove is a custom class. I presume it's necesssary to call registerClassAlias() on GameMove, but do I also have to register Vector.<GameMove>? It's it it's own distinctive type, or is it kinda composed of those two types?
I have a Panel in my application which contains 2 buttons and 3 canvas components at certain posstions...now I want to store the current state of panel in some file or database...and afterwards I want to load the same panel again in my application when I come back and run the application. I tried to convert whole panel into ByteArray object using its readObject() and writeObject() methods...but when I read the ByteArray and add the panel in my application using addChild() method it doesn't add anything and there was no error or fault...
writeObject creates ByteArray that I am able to print but when i get it back and add child, I am not able to get the panel and it's children.
I recently came into a situation when sending a nested object from Java to Flex via a HashMap the Objects were null. More precisely:final Map< Integer, List<String>> tempMap = new HashMap<Integer, List<String>>();would send the keys as integers but the values were all null.But when sending the same with String keys:final Map<String, List<String>> tempMap = new HashMap<String, List<String>>();the objects came thru.Are there any restrictions in BlazeDS serialization when using complex types as keys?
Is there any way, without having the creator of the object implement any special functions (no specific serialization functions) (however, they can use annotations), to have Flash serialize a generic, possibly deep (objects within objects within objects, etc, etc, etc) object?
how to publish live video feed from webcam in h.264 format non VP6 format with FMS 3.5.2 without using Flash Media Live Encoder, and how to set all parametersto have a good quality and smooth video without interruption, i have a server with 50Mbit bandwidth output enough for a publisher and 10 clients meunderstand this thing's been months since I try but the quality ugly
I'm building a realtime action multiplayer game in Flash which is using too much bandwidth because it sends message objects as XML (as required by the Smartfox server). I'm now trying to cut down on that by serializing my objects to strings before feeding them to Smartfox. I've tried JSON but it doesn't work. Is there another serialization method that is compacter, for example that encodes numbers in Base64 instead of decimals? I don't care about human-readability in this case.
I was wondering if it is possible to do custom serialization of Arrays/ArrayCollections in as3 via amf. To be more specific, i want to be able to pool objects on the client so that im not instantiating new objects every time i make a RemoteObject call. I tried using IExternalizable but that only lets me serialize the objects myself not instantiate them. The flash player is still instantiating objects itself and them letting me set the object state via readExternal.
i need to serialize AS3 strong typed Objects, send them to a C# Application and then be able to derserialize them as Hashtables/Dictionarys or so because i have no corresponding C# Class. I then will make some changes to that Hastable and need to be able to send them back to the as3 App. I tried using JSON (see this question with bounty Typed AS3 JSON Encoder and Decoder ?) as i already got JSON serialization to Hashtables in C#. It does not work because AS3 has no support for typed JSON.
I also looked in XML and found asx3m http://code.google.com/p/asx3m/ which is strong typed in as3 but i can find a solution to serialie and deserialize this to proper hashtables in c#.
I've been looking at various questions in StackOverflow and in other sites, but I have not seen a library that a) generates actionscript code given XSDb) serializes to and deserializes from XML using the generated classes. In Java world this is JAXB. I have a set of large XSDs, based on which a web service is producing XML output. I don't want to write actionscriptclasses by hand, that'd be huge piece of work. Having source code in actionscript since writing code based on runtime binding of xml/json to objects is much more error prone compared to having proxy like classes.
I'm using BlazeDS to remote some Java objects that I'm consuming in a Flex application. I'm getting a type coercion error with one of my classes that I can't for the life of me figure out. I have other classes that are working fine using the same data types, and I've gone over my mapping a dozen times. I'm following all of the necessary conventions for getters and setters as far as I know...
Anyhow, my question is: how can I debug this problem? Running the Flex app in debug mode spits out some generic errors to the console that don't really help much (TypeError: Error #1034: Type Coercion failed: cannot convert Object@5d1d809 to valueObjects.SomeClass.).
I'm trying to use the native flex serialization/deserialization process to save/load state of a workspace in flex. In order to save or load a file I have to use my servlet, which just bounces back the bytes from the input stream to the output stream. Here's a basic outline of my Flex code:[code]So my problem here is not with the saving of the workspace. That works great. My problem is with the loading of a workspace. The event.data that I write to the byte array is not reconstituted into a MyWorkspace object even though it is exactly what I wrote to the file.There has to be a way of making a MyWorkspace object from the data, but I can't figure it out.
I want to make a textinput where a person can type in a price. I used "restrict" to only allow numbers and decimal. But the person can type in several decimals and create numbers like 11.1.1.1 or 11...11 or 1.11111
i want to restrict the entry to only one use of a decimal and only two numbers after the decimal.
any other way to format a textinput to a currency format?
Is there any library in Action Script that be able to convert any video format to .FLV?
I've been looking for it with no success. I thought that as3 had functions for that purposes but not found.
I want to give the possibility that in my site, users can upload any video, so I need to convert it to a standard and compress it to a fixed resolution.
I was using the serializing approach between Flash and PHP for the longest time before AMFPHP had its 1.0 release (wow...that was a long time ago...in 2006)!Serializing using a sepiroth's AS library paired with PHP's built in serializing functions worked and I didn't change it because it did the job.
Should I switch over to the AMF format and technology? One pro is that the data exchange is probably more efficient for AMF because it's a binary format.I've also see other scripting languages/frameworks such as Python/Django, Ruby/Rails supporting AMF. I guess AMF is also a standard format. Does each language serialize data differently?
