I'm working in an educational software, mostly developed using Flash AS3, and we have a chronometer which shows different values through different users. Example: Two users starting the chronometer at same time, but along some minutes of usage, they have different values.
The current implementation uses Timer class, causing this to happen, obviously due the different average speed of each computer.

What is the most efficient way to create this real time application ?Flash ? Long polling ? Http Streaming ? or anything else ?
I want to design a web page that will display a visual aid representing real time data. Real time for me means updating at least every few seconds, or literally realtime/event based if that is possible. The data displayed will be displayed in a rather visual/graphical way rather than simple text or a table.
I do not have a lot of knowledge of web development other than a little knowledge of HTML, so I do not know what options are available to create a web page that does what I want. My search has seemed to point towards Flash as being the technology best suited to do this, but I have also seen several articles which caution against flash (but mention no alternative).
The main alternative contender instead of Flash seems to be Comet style programming which I understand would likely utilize (in my case at least) a system called "long polling" to update data regularly. This could work, however the nature of the way I would like the information displayed leads me to believe that flash might be better than this as it sounds like longpolling is well suited for simple display of text inofrmation based on results, whereas I will need certain details of the visual display to change as well depending on results.
My research has also lead me to believe that an ASP.NET or PHP page would almost do what I want, but my understanding is that these two frameworks'/ languages' purpose is more along the lines of generation of a unique web page when loading rather than updating it as someone is looking at it.To make sure it is clear: communiciation is COMPLETELY one way in my imaginary web page. the user's display needs to update but they in no way send data back.What tools are best suited to create a webpage which will update/display (in a visual manner) data in real time in as someone is viewing it?
edit:
after finding this article: How does facebook, gmail send the real time notification?, I am thinking Comet could still be a really good option as I can just use it really as the messenger of events rather than having the direct result displayed as text or something. Still looking for advice on which way may be easier though due to my impression that Flash may be easier to program the graphics in a dynamic way.
When someone clicks in my flash activity, sometimes it triggers a lot of computation. If the user clicks again (e.g. a double click), this event gets queued and dispatched after the heavy computation is complete. If I clicked many times, the problem is just compounded -- if clicked fast enough, the queued heavy computation finishes up to ten seconds later, with each clickEvent slowly dribbling out the next task.
I have two questions. First: how can I get the accurate time for when the click took place? In the example below, I am getting the dispatch of rapid click events long after the click was clacked (sp?).
Second: what is a good design pattern for collecting every click? Off the top of my head I suppose I should

We're currently building a fairly big dynamic website, and I was wondering if there was a way to have an animation that updates and move in real time as there's action on the site. Ex. red bulbs light up each time a user posts something on the forum or whatever. It'd be all related to the mysql database.
View 1 RepliesI'm looking to create something within Flash that I've not yet seen done.It will be a shared, real-time interactive session. What I want to know is, is it possible to create an individual, private session within Flash that is synchronized between two or more computers? I am doing this for the medical profession, but I can also see this would have benefits in the gaming community as well. I'm trying to create something that two specific users can interactively share in real time.
For example,a coloring book.Two players,or as many as you want, log in together and share a private coloring session. They will be able to interactively see anything that the other person is coloring in real time.The other people would also be able to color and let everyone else see their work.
I want to do a flash that changes based on the time of day. For example to load right .swf on container MC at the right time of the day.
View 1 RepliesFlash can use the RTMP protocol to exchange data between a server and a client. How do you typically access this functionality in AS2 or AS3/Flex? For example to use sockets you use the XMLSocket (AS2) or Socket (AS3) classes. Does the server-side RTMP software use Sockets under the covers? or is it HTTP with tunneling?
The Real-Time Messaging Protocol (RTMP) was designed for high-performance transmission of audio, video, and data between Adobe Flash and a server. RTMP is now available as an open specification to create products and technology that enable delivery of video, audio, and data in the open AMF, SWF, FLV, and F4V formats compatible with Adobe Flash Player.
One thing that's really frustrating me about Flash is that the info panel doesn't display real-time width or height values.So if I'm drawing a rectangle, I can't just draw it out as do in Photoshop to say 400 X 200. I'll need to set this manually after I draw a small box.

I am creating a game where I have some red balls on the screen and some blue balls on the screen and I would like to draw a polygon around all balls of the same color and have this polygon automatically fill as soon as the polygon shape is closed. How to achieve this as I haven't really done much with the drawing API before. My current code will allow me to draw a polygon and for it to fill when I release the mouse but what I would like it to do is automatically fill as soon as the shape is closed.
Here is my code so far
Code:
var graphix = new MovieClip();
addChild(graphix);
var points:Array = [];
stage.addEventListener(MouseEvent.MOUSE_DOWN, startDrawing);

The timer class seems to accrue a lot of error over time so I'm wondering what other solutions people have come up with for a more accurate Timer.
View 4 RepliesI'm trying to playback some sample data through the new real-time audio capabilities of Flash Player 10. I started with the example given at the bottom of this page on livedocs, which seems to work fine and plays a crystal clear tone.I assume that the two writeFloat's in the example write to the left and right audio channels respectively and that the data being written is 32 bit (because of the float).
However. I seem to be having trouble converting my old 8 bit audio data to a format that is understood by this interface. When I playback my sample data I can vaguely hear the sound I'm expecting but it is massively distorted. My sample data consists of raw 8 bit samples that ranges from 0..255 where 127 is silence.
I've been trying different conversion formulas but I seem to be missing some vital information regarding this conversion.
UPDATE:The correct formula turns out to be:
f = (sample.data.readByte() - 127) / 255
Here is my problem: We are broadcasting sportevents live to the internet via flash media encoder.At the event locations we mostly have just 2 mbit upstream. So at the moment we are streaming with about 1mbit rate.But we need also streams for mobile-devices and a stream for users without fast internet. So we want 2 more streams with lower-bitrates,but we can't get this through the 2mbit...I am looking for a solutiuon which can transcode about a 1mbit(and may be in the future a 1.5mbit) livestream in to two (or more)lower-bitrate streams.The solution should be scalable,because sometimes we have 7 events at one day on different locations,so there could be 7 input-streams.I've searched the net for hardware transcoders, but didn't find a stable solution and I've tested also transcoding with ffmpeg, but it seems to get problems with timing and key-frames for bitrate switching.
View 3 RepliesI am developing a non-real time browser RPG game (think Kingdom of Loathing) which would be played from within a Flash app. At first I just wanted to make the communication with server using simply URLLoader to tell PHP what I am doing, and using $_SESSION to store data needed in-between request. I wonder if it wouldn't be better to base it on a socket connection, an app residing on a server written in Java or Python.
The problem is I have never ever written such an app so I have no idea how much I'd have to "shift" my thoughts from simple responding do request (like PHP) to continuously working application. I won't hide I am also concerned about the memory and CPU usage of such Server app, when for example there would be hundreds of users connected. I've done some research. So, considering the fact I don't need real time data exchange, will it be wise to develop the server side part as socket server, not in plain ol' PHP?
I am looking for a watch expression debugger for Flash AS3 (not flex). I have found this: demonsterdebugger but the refresh is not in real time (like the trace does), it has a lag of 3 seconds. It is important because i am developing a flash box2d game so I need the coordinates while playing.I've tried also KapInspect with the Digiex pluging, but it gets down the framerate and it is embebbed. So it is not good for me. Can you please tell me one good debugger? I am using Flash Builder 4 (it has not whach expression inspector)
View 1 RepliesI'm attempting to code a system to handle real-time refraction and reflection of light in 2 dimensions (on an x, y Cartesian plane, basically) and I'm hitting my head against the wall even figuring out where to start on this. My concept for how this should behave goes like this: There is an object that shoots a ray of light (a laser beam or something) toward a target object. When the ray intersects with the surface of the target, somehow I need to find the normal vector to the surface of the shape at the point of intersection and apply some equations from first year physics to alter the path of the ray appropriately. The same refraction effect takes place as the ray exits the object. At the moment, I'm grasping for straws. I'm not even sure what kinds of objects exist in Flash's libraries that will work for me with this. The existing libraries for shapes won't let me create lenses like I want to, and I'm not sure what I'll need to make for an adequate "light" projectile or line to take on this behaviour.

View 1 RepliesI'm currently using the Graphics library to draw bands of color across an image (bitmap).So, I draw a square of colored bands, and mask it with the bitmap image. Unfortunately, when I use a mask (or even set the blend mode to .LAYER, OR use a shader filter) the FPS drops to un-usable levels.Is there some way that I can draw the bitmap shape I want without killing the FPS? I was thinking that I could like, draw the bitmap on top of the sqaure of Graphics, and then make a certain color transparent.

View 6 RepliesI have a C executable (named myprogram). When I run it by ./myprogram I get some output statements on the standard output of my Linux shell. I used run.php to get access to whatever is being printed to the standard output:
#run.php
<?php
$output = shell_exec('./myprogram');
echo $output;
?>
Then I called an HTTPService having id="service" to access this run.php file and I also set the text attribute of a TextArea to {service.lastResult}. When I run my Flex app, the interface kind of halts for a moment and then the TextArea displays all the 20 lines at once. But if program is run from Linux shell they appear one by one. Is there a way by which I can display a line as soon as it gets printed to standard output? This will then make the TextArea show the output in real time.
Or is Flex unable to do this? Rather how can a PHP program achieve such effect i.e. showing, whatever is being printed on standard output, concurrently in the browser in real time? Myprogram outputs 20 lines each after some microseconds. I want only the first line of standard output to appear in TextArea of Flex or in the browser (but in real time) while the program may then continue running the program.
I have a Flex/AIR application communicating with a PHP server application. Recently my client requested real-time-like connectivity between the applications to replace what we currently have; refresh buttons which have to be clicked to refresh data.So effectively the server needs to push data to the client when something changes. I can write the code that detects when something changes, but I'm not sure about the push side of things.
