I have my class[code]...
MyClass is made for serializing but problem is that data property is Object which is not serializable. I have data property because I need to put some simple variables (data.id, data.name ...) in it and I needed to be serialized as anonymous object.
I'm about to implement
public function writeExternal( output:IDataOutput ):void {...}
public function readExternal( input:IDataInput ):void {...}
to make a set of object serializable.
Although I'm pretty sure, that I implemented all correctly, readExternal(..) at a certain point complains about too few data left to read:
RangeError: Error #2006: The supplied index is out of bounds.
at flash.filesystem::FileStream/readObject()
I wonder, if I have a circular object network like
A = { left -> B, right -> B }
B = { father -> A }
And I call
writeObject( a )
Will Flex serialize the hole object network and each object once and only one?
I did this:
Declared type annotations like this: [RemoteClass(alias="model.MyClass")]
Implemented parameter-free constructors
Declared all classes using implements IExternalizable
SharedObject's send() method is guaranteed to send each object once and only once.
Additional infos:
Reading and writing a ByteArray
Using Remote Object Components
IExternalizable interface
Currently, I do serialize my model object to the SharedObject instance:
try {
var mySo:SharedObject = SharedObject.getLocal("sig");
mySo.clear();[code]....
Likewise, I load the saved model using the SharedObject instance. Works great.Ultimately, I'd like to serialize it to a file - which fails. Here is how:
var fp: File = File.applicationStorageDirectory;
fp = fp.resolvePath( PREFS_FILENAME );
var _prefsStream:FileStream;[code]....
The complementing read operation suddenly breaks and reports missing bytes.In fact, I can't image how FileStream / _model.writeExternal() is able to serialize, since it needs to somehow know, that a new serialization operation is about to start. If it doesn't know, it won't be able to determine, which object instances are left to serialize.Thus, I image that my concept is completely wrong or I missed how to initialize the serialization operation.I'd be happy to read the raw ByteArray from the shared object and write it to a file. Unfortunately, I didn't find a method to retrieve from a SharedObject a ByteArray of a certain property, in my case mySo.data.model.My question is loosely related to this one: Why does delete( DictionaryInstance[ key ] ); fail?
How can I serialize XML(meaning convert < to < and > to > etc...) using AS3. is there any build-in functionality or I have to use some regular expression to make global changes?
View 1 RepliesI'm new in JSON, but now I need to use JSON for my Flash ActionScript 3.0. So I found one lib for JSON and I have seen the terms Deserialize & Serialize what does that means.

I want to serialize an object to AMF, and I want the result to be exactly the same as if it is serialized by NetConnection.call(). So, I use ByteArray.writeObject(), and the output bytes are usually the same as bytes sent by NetConnection.call(), but sometimes couple of bytes are different.
I found this in AMF3 spec: "Note that ByteArray.writeObject uses one version of AMF to encode the entire object. Unlike NetConnection, ByteArray does not start out in AMF 0 and switch to AMF 3 (with the objectEncoding property set to AMF 3)." It explains that differences.
We are developing an app with a Flex frontend and a C# backend, connected through web services. We are using the FLex Builder 3's Web Service Manager to autogenerate the webservice classes. The problem araise when Flex serialize our objects, for example, when we have a Number property with no value, this is serialized as NaN, and our backend doesn't know about NaN. Another example is when we serialize a cyclic reference, we get a stack over flow exception. I know in java, for example, you can configure the way xstream work with cyclic reference... So, the question is, can we change the way Flex serialize the objects so C# can work with this frontend? Is there any issue we should know about how flex serialize objects?
View 4 RepliesIs it possible to serialize (or equivalent) a Flash movie clip object or graphic object? I'm trying to find out if it's possible to send such an object via XMLSocket.send.
View 3 RepliesCan a Flash graphic symbol instance be serialized (or equivalent) for use in an XML.send or an XMLSocket.send call?
View 3 RepliesAt the moment it seems I've tried every trick in the book trying to get this to work. I need some way of encoding AMF requests and then decoding the responses. At this point I don't care what language it's in, as long as it's doable and free (as in to me), however I would prefer PHP.I don't know what other information is needed
View 2 RepliesI'm having some troubles with the use of interface and inheritance in AS3. I've done lots of OOP in the past and what I'm trying to do seems obvious to me, but doesn't work in AS3. The question is : Is it possible to override a function that return an Object of class A, and make it return an Object of Class B which extends A ? It seems not to be possible, since I'm getting a signature error in Flash, when compiling. For example, the following set of class do not compile (the code in function definition doesn't matter):

I have a class CoverPoint extends Pointwith some extra function.except for that ther is no difference. I would like to use the functions of Point with a return value of Point, to calculate those CoverPoints.Can i turn the return value into CoverPoint (since all the vars are the same, there shouldn't be a problem with that, right?), so that it can be stored in my var cP:CoverPoint;
View 2 RepliesIf I have three classes:
public class Example {
public function Example () {
}[code]............
You can see that the two last classes extend the first one, and both have the 'variable' property. In case that I have an instance of Example and I am sure it is also an ExtendedExample OR AnotherExtendedExample instance, is there some way to access the 'variable' property? Something like
function functionThatReceivesAnExtendedExample (ex:Example):void {
if(some condition that I may need) {
ex.func()
Using Flash CS5 Professional I have created a symbol, dragged it onto the stage, and given it an instance name of GreenLight1. If I want to make this visible from the document class, I can simply do the GreenLight1.visible=true; and poof it's good to go when I test the file. As long as I stay in the document class I am good to go, but now I'm trying to move to another class and hitting ALL kinds of trouble just trying to get Flash to allow me to access this simple object. All I am looking to do is have this GreenLight1 go invisible (visible=false) when a certain condition occurs in this new class and Flash just won't let me access GreenLight1 at all. Things I've tried thus far:
stage is passed to the class and is referenced by _stage and is working just fine when I do _stage.addchild or anything like that. So I have tried "_stage.GreenLight1.visible=false;" and I get "ReferenceError: Error #1069: Property GreenLight1 not found on flash.display.Stage and there is no default value." My document class extends Sprite, so I figured I'd try the root function. So I tried "Sprite(root).GreenLight1.visible=false;" and I get "1119: Access of possibly undefined property GreenLight1 through a reference with static type flash.display:Sprite." I tried to create the Resource class as described therein. To which I came across the same problem that I started with in that it doesn't know what GreenLight1 is to begin with so I got "1120: Access of undefined property GreenLight1." Here is my code for Resource.as (am I supposed to pass something to this class from the document class?)

I have question regarding removing instantiated objects. Let's say i have a main class in which i instantiate a custom video player (or whatever) class:
[Code]...
From my experience, if i don't destroy for example event listeners from my VideoPlayer class and just remove VideoPlayer class the way described they still get fired with null exception messages etc. This is something that's bugging me for a while so i would really like to know what's best thing to do here?
When I use MouseEvent.MOUSE_OUT the target is [object MovieClip], but when I use MouseEvent.ROLL_OUT I get [object Bildspel] - and Bildspel is my class. The thing is that when I use ROLL_OUT I'm not able to delete the targets ENTER_FRAME event.
[Code]...
Ok. So heres what I am trying to do. I want one movie clip to follow another one that I move around with actions on the main timeline.The problem is that the follower clip is linked to a class file and I cannot find a way to find the players position.

I found myself loading a new XML file every day and so decided to create a small class that will load the xml file and return it.The class is loading the file but when i try to return it to a new xml object in the document class it doesnt load it.I think that it's something to with the return being in a nested function but i tried a few ways and non seems to work.

I have created a class, call it Class1, that has various objects drawn on the stage (drawn in the IDE). It also has a function, called setColour, for changing the colour of those objects. The function works fine if I call it from within Class1.
Now I have another class, call it testClass1, that imports Class1 and calls the setColour function. First of all, none of the stage objects from Class1 are visible. Secondly, when setColour tries to modify the colour of an object, I get the error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
This is the code for testClass1:
ActionScript Code:
package
{
import flash.display.*;

So, what is the problem? Is it possible to change objects that are drawn on the stage of an imported class?

View 3 RepliesThe following is that long only because I gave examples of what I want to know, not because it is complex .I have three basic questions regarding AS 3.0 classes.
1. How can I make a class object interact with an object on stage?
For example, when I have a square (mc_Square) with class "square" attached to it and I want it to trace "Colliding!" and print the X and Y of the mc_Box on contact with an on-stage *hollow* box (mc_Box) that has no class attached to it.how to do it vice-versa would also be awesome .
2. How can I make a class object interact with the same class object? For example, when I have two squares (mc_Square) that both have the class "square" attached to it and when they collide, it prints the X and Y of both of them.
3. How can I make a class object interact with a different class object?
For example, when I have two squares mc_Square1 with class "square1 (that also has a variable Primary=true written in it)" and a mc_Square2 with class "square2"; When they collide, the one with Primary=true would be removed and it's X,Y position traced.

I'm new to Flash AS3. I started making a game and I am a bit confused. Let's assume that I want to create a game that has multiple levels/modes, how can I do this in an object orientated way?

In Flex, say I have a Class object. How do I get a string for the class it represents?
e.g.:
