[Flashcoders] bytesAvailable, readUTF() and ProgressEvent.SOCKET_DATA
Hello,
I have multiplayer game, which reads XML data from the server:
_socket = new Socket();
_socket.addEventListener(ProgressEvent.SOCKET_DATA, handleTcpData);
.
private function handleTcpData(event:Event):void {
while (_socket.bytesAvailable) {
var str:String = _socket.readUTF();
updateGUI(str);
}
}
In most cases it works ok, but sometimes users complain that
the game hangs for them. They are able to send in commands to
the server, but from their descriptions I suspect, that the function
above doesn't work well for them and the updateGUI() stops being called.
This issue is difficult to debug... I think my server (in Perl/C,
non-forking, uses poll()) works well, I must be doing something
wrong at the Flash side.
Is it a good idea to call readUTF() here? It could well be that
only part of the UTF string arrives and then the Flash movie
would freeze in readUTF(), wouldn't it? (I've never seen that though)
Regards
Alex

Re: [Flashcoders] bytesAvailable, readUTF() and ProgressEvent.SOCKET_DATA
Doing anything but copying the data from the event to your own bytearray buffer object is a disaster waiting to happen. TCP is a stream based protocol, you can get chunks of any length each time the event is reviced. Assume that the chunks are random length and piece them together in a buffer of your own. Then, once you know that you have a full logical unit, process the data. ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

Re: [Flashcoders] Finding and Removing a Sprite
Hi Theodore, When you say 'addChild(mySprite)' mySprite *is* the child of something: the instance you call addChild on (addChild(mySprite) is equal to this.addChild(mySprite)) To remove mySprite you have to call removeChild(mySprite) on the same instance. From the error it seems that myChild is not a child of the instance you call removeChild on. Did you trace mySprite.parent to see if mySprite is actually a child of an instance? (traces null if mySprite is not a child of anything, traces the parent if mySprite is added as a child) parentName.removeChild(mySprite) does the trick then.

RE: [Flashcoders] Event.COMPLETE Question
I presume my removeEventListener works.
You should be sure. So check it:
trace(e.currentTarget.hasEventListener(Event.COMPLETE)); //true
e.currentTarget.removeEventListener(Event.COMPLETE, loaded);
trace(e.currentTarget.hasEventListener(Event.COMPLETE)); //false
So, how do I pass new values to fn loaded?
Just increment the vars.
// Cascade layout
displayObject.x = myX + 31;
displayObject.y = myY + 31;
myX += 20;
myY += 20;
Have you considered putting your url strings into an array instead of using
that awkward switch statement?
I would also recommend writing a function that creates and returns
BevelFilter. Set 'myBevel' once (rather than running through the code
repeatedly) then apply it where appropriate.
var myBevel:BevelFilter = createBevel();
function createBevel():BevelFilter{
var bf:BevelFilter = new BevelFilter();
bf.type = BitmapFilterType.OUTER;
bf.distance = 10;
bf.highlightColor = 0xFF;
bf.shadowColor = 0x00;
bf.blurX = 20;
bf.blurY = 20;
return bf;
}
// apply Bevel filter
displayObject.filters = [myBevel];

[Flashcoders] accessing event dispatchers in a loosely-coupled, modular design
Following the discussion about root yesterday, it got me thinking about a constant problem I face. Object-A needs to listen to events coming from objects B, C and D, but only if and when these objects actually exist. There's no guarantee that any of the objects B, C and D will be instantiated before or after A is instantiated. So, what's the proper way for A to add itself as a listener to B, C and D? What I'm currently do is this: The event dispatchers (B, C, D etc) implement a singleton interface. Within the target (A), I set up a Timer event to repeatedly check for instances of the dispatchers. Once a dispatcher is found, the target adds itself as a listener, and a pointer to the dispatcher is created so that the target can later remove itself. I'm not very happy with this design, but it's the best that I've been able to come up with.

RE: [Flashcoders] accessing event dispatchers in a loosely-coupled, modular design
If an instance of those classes has been created, then it will eval to true, otherwise it will be null, so this should work for that part of the problem: if(_myinstance) _myInstance.addEventListener(myEvent, myHandler); However, if you're creating A after B, C, and D, then you'll want to call the code above from say, a Controller class whenever A is created. Once A is created, then that's a trigger to add the listeners to the other classes if they exist. Make sense?

I presume my removeEventListener works.
You should be sure. So check it:
trace(e.currentTarget.hasEventListener(Event.COMPLETE)); //true
e.currentTarget.removeEventListener(Event.COMPLETE, loaded);
trace(e.currentTarget.hasEventListener(Event.COMPLETE)); //false
Thanks. Traced true.
So, how do I pass new values to fn loaded?
Just increment the vars.
// Cascade layout
displayObject.x = myX + 31;
displayObject.y = myY + 31;
myX += 20;
myY += 20;
How is that? I'm not iterating over that function, I call it as needed, so
myX, myY would be reset every time.
Have you considered putting your url strings into an array instead of using
that awkward switch statement?
This worked. Thanks:
public function thePic(x:int,
y:int)
{
var paths:Array = new Array(images/bracelet.jpg,
images/brooch.jpg,
images/chain.jpg,
images/earring.jpg,
images/necklace.jpg,
images/ring.jpg);
var path:String = new String();
path = paths[counter];
var req:URLRequest = new URLRequest(path);
var loaderArray:Array = new Array();
loaderArray[counter] = new Loader();
loaderArray[counter].load(req);
loaderArray[counter].contentLoaderInfo.addEventListener(Event.COMPLETE,loaded);
}
I would also recommend writing a function that creates and returns
BevelFilter. Set 'myBevel' once (rather than running through the code
repeatedly) then apply it where appropriate.
var myBevel:BevelFilter = createBevel();
function createBevel():BevelFilter{
var bf:BevelFilter = new BevelFilter();
bf.type = BitmapFilterType.OUTER;
bf.distance = 10;
bf.highlightColor = 0xFF;
bf.shadowColor = 0x00;
bf.blurX = 20;
bf.blurY = 20;
return bf;
}
Thanks.
// apply Bevel filter
displayObject.filters = [myBevel];
No:
displayObject.filters = [createBevel()];
TIA,

Re: [Flashcoders] Finding and Removing a Sprite
Hi Theodore,
var mySprite:Sprite;
Do this:
function createBar(dfile:String):void {
...
mySprite = new Sprite();
function createGraph():void {
mySprite.graphics.
addChild(mySprite);
}
}
You declared mySprite inside the function, so it's not accessible
outside that function.
Declaring mySprite outside the function makes it accessible to other
functions.

maybe you shouldn't ignore thrown errors: AFAIK if the UTF8-data is not

will throw an EOFError error. so if you handle this error correctly, you

You declared mySprite inside the function, so it's not accessible outside

Hi Theodore,
When you say 'addChild(mySprite)' mySprite *is* the child of
something: the instance you call addChild on (addChild(mySprite) is
equal to this.addChild(mySprite))
To remove mySprite you have to call removeChild(mySprite) on the same
instance.
From the error it seems that myChild is not a child of the instance
you call removeChild on.
Did you trace mySprite.parent to see if mySprite is actually a child
of an instance? (traces null if mySprite is not a child of anything,
traces the parent if mySprite is added as a child)
parentName.removeChild(mySprite) does the trick then.

In other words: Create a Controller class before creating any other classes. Any instances that need to know when potential event dispatchers are created should listen to the Controller class. When dispatchers are created, the Controller class should dispatch an event. This way I won't need to use a Timer to repeatedly look for the dispatchers.

Once A is created, then that's a trigger to add the listeners to the other classes if they exist. Make sense?

something like bar.name = String(bar_ + i); but personally i'd use an
array like so...
var bars:Array = [];

{
var bar:Sprite = new Sprite();

addChild(bar);
bars.push(bar);

then you can get at the bars later to do stuff with them or remove them...

RE: [Flashcoders] accessing event dispatchers in a loosely-coupled, modular design
Sort of - but I wouldn't have the controller dispatch anything. I would only have it listen to the view(s) (your other classes with a visual presence). The controller first creates an instance of A (what determines when that happens, I don't know because I don't know what A or your app is all about). When it does, it also creates listeners for B, C, D if they are present in the view. Controller also of course has the handler that tells whatever else to do what it has to do (now I'm just guessing because I don't know what you're ultimately trying to accomplish). If something needs to happen when something changes data-wise in the model, then you would listen to the model which dispatches events and have the controller respond, perhaps by telling the view to change. IMO, the Controller is the most ambiguous part of the MVC pattern. View and Model are pretty straightforward (esp. the Model). Different people have different ways of using the controller, but this is how I use it. It listens to other parts of your app, and then tells other parts of your app to do something. It's the central nervous system to use a methaphor - at least how I use it. AS3 Frameworks get more broken down than that, using things like Command classes, Mediators, and Facades and junk for even better OOP development and control, but there can be a steep learning curve to most of those frameworks.

And add each newly created bar to the array.
Afterwards, say in another function, you can reference the array
indexes.
Something like:
myBarsArray = new Array();
function createBars():void
{
for (var i:int=0; itotalbars; i++)
{
var bar:Sprite = new Sprite();
...
addChild(bar);
myBarsArray.push(bar);
{
}
function removeBars(i:uint):void
{
removeChild(myBarsArray[i]);
//don't remove the bar from the array
}

Re: [Flashcoders] Finding and Removing a Sprite: PART II
Inside your loop, you can add the sprite to a movieclip and give each movieclip
a name using the variable in your loop like:
mcName.name = mc+i; //or whatever your for loop var is
And then remove it by getChildByName(mc#);

How is that? I'm not iterating over that function, I call it as needed, so myX, myY would be reset every time. Uses the addition assignment (+=) operator. No: displayObject.filters = [createBevel()]; You are missing the point. Why run this function repeatedly when you can set 'myBevel' once and just use that? displayObject.filters = [myBevel]; Regards, Keith Reinfeld Home Page: http://keithreinfeld.home.comcast.net ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

RE: [Flashcoders] Finding and Removing a Sprite: PART II
I agree with Mr. Tom Rhodes. Storing references to your buttons in an
array is far better than trying to create and use dynamic instance
names like bar+i. You can tack on data properties to the buttons as
well, so they have information about themselves that travels with them.

Glad you got it fixed. I'm late to the discussion, so didn't
contribute anything yet--but I will now :-)
Do yourself a favor now. One of the real advantages of AS3 is
eliminating timeline code--you have to do that eventually to take
advantage of AS3's OOP capabilities.
Make a backup of your .fla before you do this, in case something goes wrong.
In the same folder where your .fla file is, create an ActionScript
file called Main.as. Inside it, use this:
package
{
public class Main extends Sprite
{
//functions go here
}
}
Now cut and paste all your code from the timeline and put it after the
line //functions go here. You can overwrite that line--just keep your
functions in between the inner set of curly brackets.
In the .fla file, in the Properties window, set your document class to
Main. Remember, ActionScript is case sensitive.
It should compile and run the same as before, but you will have taken
a good first step towards utilizing AS3's power.
Cordially,

Re: [Flashcoders] Finding and Removing a Sprite: PART II
I think it depends on the circumstances:
If you are not manipulating the child sprites in any way, just adding
them at the start, removing at the end and possibly listening for events
on them, why would you want to use more memory by storing the sprite
instances in an array or a vector when you already have a storage medium
for them - the parent container?
If I was needing to move things around, or juggle the display order, or
manipulate sprites in the container, I may want to store a reference to
them, but if they are just display elements, it's even simpler just to
add them to a container sprite then iterate through the container when
you are done with them if you need to remove listeners.
Obviously this is purely down to coding preferences, but why waste
arrays, when your DisplayObjectContainer does it for you...

You can use the addChildAt method and tell it where to add the object in the

addChildAt(objectName, 0); will add the objectName to the bottom of the display

RE: [Flashcoders] Finding and Removing a Sprite: PART II
IMO, an array is hardly a waste of space, and allows for expanding your
app easier if need be, but you're right, could come down to coding
preferences in that case. More often though I think, the benefits of
storing them in an array outweigh the benefits of dynamic naming.

We're talking about only nine instances here. It would be a different matter if it were tens or hundreds of thousands, but even then the additional memory required to store another reference to them would be insignificant compared to the memory the Sprites themselves would use, and performance would be the far bigger issue. So, a descriptively named collection has a higher benefit, for readability alone. Preferably a Vector, so casting isn't necessary even when the Sprites for the bars become a proper Bar class, as they probably should. I'd still put them in their own container, though. Then the container goes on top of another with the lines. ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

Re: [Flashcoders] Event.COMPLETE Question
When loading bitmaps, your loader will NEVER be eligible for cleanup by the
Garbage Collector unless you do ALL of the following in this order:
var bitmap:Bitmap = new Bitmap(Bitmap(loader.content).bitmapData.clone(),
auto, true);
Bitmap(loader.content).bitmapData.dispose();
loader.unloadAndStop(true);
try {
loader.close();
} catch (e:Error) {}
// remove all event listeners from loader
This means that if you want the Bitmap from the loader, you should extract it
using bitmapData.clone(), or your Bitmap will be gone when the loader goes away
or the loader will not go away because there's still a reference to its BitmapData.
If you're pulling a Bitmap out of an anonymous loader by saying
addChild(loader.content) you will never have another opportunity to get rid of
the loader. That may be ok for your purposes, but this is a very good reason to
addChild(loader) so you maintain a reference to the loader itself.
Unless you have a specific reason for not using addChild(loader) you should use
the code block above.
It's important to note that you won't see your memory go down unless you force
the GC to run after you null out all references to the loader. In AIR you can
say System.gc(). In Flash, you have to use the unsupported LocalConnection hack.

Re: [Flashcoders] Finding and Removing a Sprite: PART II
yeah, horses for courses... if you want to better encapsulate stuff, i find it easier to work with arrays (in fp10 vectors) and pass them around if needs be. tying your code to specific timelines gives you more work to do if you want to reuse that code imho. for something quick and dirty in timeline code though that you know you don't want to reuse then whatever's clever.

Re: [Flashcoders] bytesAvailable, readUTF() and ProgressEvent.SOCKET_DATA
I've come up with this, but still have a flaw there:
private function handleTcpData(event:Event):void {
var len:uint;
if (0 == _socket.bytesAvailable)
return;
try {
_socket.readBytes(_ba, _ba.bytesAvailable,
_socket.bytesAvailable);
// read the length of the UTF string to follow
while (_ba.bytesAvailable = 2) {
len = _ba.readUnsignedShort();
// invalid length - reset

_ba.position = 0;
_ba.length = 0;

}
if (_ba.bytesAvailable = len) {
var str:String = _ba.readUTFBytes(len);
updateGUI(str);
// copy the remaining bytes
// (does it work? can it be improved?)
var newBA:ByteArray = new ByteArray();
newBA.readBytes(_ba);
_ba = newBA;
}
}
} catch(e:Error) {
trace('XXX ' + e);
_ba.position = 0;
_ba.length = 0;
return;
}
}
- when there are too many bytes available, for example 800
and my messages are only 400 bytes long, then it stucks.
Also I wonder, if copying remaining bytes could be
improved (i.e. without allocating a new ByteArray each time)?

var str:String = _ba.readUTFBytes(len);
updateGUI(str);
// copy the remaining bytes
// (does it work? can it be improved?)

- the newBA.length stays zero.
Please help me with this little bit.
My problem is that when I read many bytes into my _ba
(i.e. if I read several messages at once) and then
process one message (with the updateGUI() above),
how do I get rid of those processed bytes?
I suppose I must somehow cut those processed
bytes away from the beginning of the _ba,
that is why I introduced copying into a newBA above,
but this doesn't work.

so then why did you start with posting code here (pasted below) that
didn't contain any exception catching? that's the crucial point: you
have to catch the exception, otherwise you would either get corrupted
UTF strings or and be caught in an infinite loop (because you used
while instead of if!).
here the code you had posted (that is quite different to mine):
_socket = new Socket();
_socket.addEventListener(ProgressEvent.SOCKET_DATA, handleTcpData);

When it does, it also creates listeners for B, C, D if they are present in the view. Controller also of course has the handler that tells whatever else to do what it has to do (now I'm just guessing because I don't know what you're ultimately trying to accomplish). If something needs to happen when something changes data-wise in the model, then you would listen to the model which dispatches events and have the controller respond, perhaps by telling the view to change. IMO, the Controller is the most ambiguous part of the MVC pattern. View and Model are pretty straightforward (esp. the Model). Different people have different ways of using the controller, but this is how I use it. It listens to other parts of your app, and then tells other parts of your app to do something. It's the central nervous system to use a methaphor - at least how I use it. AS3 Frameworks get more broken down than that, using things like Command classes, Mediators, and Facades and junk for even better OOP development and control, but there can be a steep learning curve to most of those frameworks.

Object-A needs to listen to events coming from objects B, C and D, but only if and when these objects actually exist. There's no guarantee that any of the objects B, C and D will be instantiated before or after A is instantiated. So, what's the proper way for A to add itself as a listener to B, C and D? What I'm currently do is this: The event dispatchers (B, C, D etc) implement a singleton interface. Within the target (A), I set up a Timer event to repeatedly check for instances of the dispatchers. Once a dispatcher is found, the target adds itself as a listener, and a pointer to the dispatcher is created so that the target can later remove itself. I'm not very happy with this design, but it's the best that I've been able to come up with.

[Flashcoders] How to remove bytes from the beginning of a ByteArray?
Hello, sorry, but I'll try to start another thread to explain my problem. I read data from a socket into a ByteArray _ba and keep inspecting it. When there is enough data, I'd like to extract and process it and remove the processed bytes from the _ba. Here is how I try to do the removal, but it doesn't work (newBA is empty) var newBA:ByteArray = new ByteArray(); newBA.readBytes(_ba); _ba = newBA; My complete code is at: http://pastebin.com/esz4As6D Thank you Alex ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

Ok, here your suggestion again:
private function handleTcpData(event:Event):void {
if(_socket.bytesAvailable) { // USE IF, NOT WHILE!
try{ // CATCH THE EXCEPTION
var str:String = _socket.readUTF();
updateGUI(str);
}catch(e:Error){}
}
}
The problem is that you read an UTF string with prefixed length just once.
But since it's TCP sockets, data can arrive in different amounts.
And in fact I see that sometimes not just one,
but several UTF strings with prefix will arrive.
But your if-code will process just the 1st one.
And another problem with that code:
if a half of a string arrives, then it will throw an EOFError,
then go into the empty catch branch and just lose that data.
Regards
Alex

Re: [Flashcoders] bytesAvailable, readUTF() and ProgressEvent.SOCKET_DATA
After some thought... the 2nd case (not enough data arrived)
is not a problem for your code, because the handleTcpData()
will get called again - once the rest of the data arrived.
But for the 1st case (several UTF strings arrived at once)...
Maybe I should try the following (and don't need a ByteArray):
private function handleTcpData(event:Event):void {
// KEEP EXTRACTING UTF-STRINGS
while(_socket.bytesAvailable) {
try{
var str:String = _socket.readUTF();
updateGUI(str);
}catch(e:Error){
// INCOMPLETE STRING, WILL BE READ LATER
return;
}
}
}

yes, I think that might be a good idea: the problem I saw peviously was
that if bytesAvailable0, but for some reason the try-statement fails
(and therefor bytesAvailable isn't set to 0), you would be caught in an
infinite loop, because I don't think the socket data will be updated
from outside while you are inside such an endless repeat-loop.
but by adding this return statement that leaves the loop this can't
happen anymore. good luck :-)

Re: [Flashcoders] How to remove bytes from the beginning of a ByteArray?
Hi, You've got the source / destination backwards. readBytes reads *from* the object on which the method is called. And it writes *to* the ByteArray you pass in the first parameter. So this: var newBA:ByteArray = new ByteArray(); newBA.readBytes(_ba); _ba = newBA; Is copying data *from* newBA *to* _ba. You want the opposite, so it should read: var newBA:ByteArray = new ByteArray(); _ba.readBytes(newBA); _ba = newBA; You can also do the read / write in place. It's a just bit more contrived but I'm not sure if it's worth it (it's less readable, I think). Here's how you'd do it, anyway: // let's assume for brevity that you've read 6 bytes from your original buffer and you still have data left (i.e., len 6) var offset:int = 6; // how much to read? All of the remaining data, which is the current length, minus your current position (we said it was 6) var newLen:int = _ba.length - offset; // Read the data starting at current position and write it to the same buffer, starting to write at the first byte. // 0 is the offset in the *destination*. We want to copy the 6th byte into the 0th position, that's why we pass 0. // the third parameter tells the method how much to read from the *source* // for what you want you don't actually need to pass these two last parameters, since by default readBytes will write to *dest* at offset 0 // and will read from *source* all available data (i.e. from current position to length -1) _ba.readBytes(_ba,0,newLen); // you do need to set this since this read/wirte is in place and you want to shrink the buffer. Othewise, you'll end up with garbage after at the end of the byte array. _ba.length = newLen; And that's it. Hope it helps.

Re: [Flashcoders] Event.COMPLETE Question
If you call close() on a Loader and it fails for any reason, it will throw a runtime error that you can do nothing about. To avoid this, you should wrap it in a try catch. The code block comes straight from Flex and it works. If you test it a bunch and close() never fires an error, then you can remove it. It's really not that much overhead to keep it in unless you're doing hundreds of iterations per second. ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
Re: [Flashcoders] How to remove bytes from the beginning of a ByteArray?
FWIW, flush() does nothing in AS3. Bytes written to the Socket are sent immediately. Anyone who tells you otherwise has never tested it and you can safely ignore them! :) Adobe has acknowledged this as a documentation bug (whatever that means).
