well, there is saveFrame() and the freshly revived AIExport library ...

... or you could talk to flash in many ways. for example:

hope this get's you started.

Obviously it was some time ago that this thread was originally posted and discussed, but I figured it couldn't hurt to put in some documentation on how Processing -> Flash can work.

The best and simplest way I have found is to create a server in Processing, and have it send the variables to Flash, which it then recieves using an XML socket object.

here is some example code using a comma as a delimiter (divides the variables being sent in the same stream)

Processing:

Code:

import processing.net.*;

int port = 9001;
Server myServer;
//variables for sending
byte zero = 0;
int total = 1;
int total2 = 2;

void setup(){
size(200, 200);
myServer = new Server(this,port);
}

void draw(){
myServer.write(total+","+total2);
//the trick is this next line that sends the "0" termination byte unaltered and alone, this way it doesn't get evaluated with the other variables being sent
myServer.write(zero);
//"zero" is the termination byte, which Flash's XMLSocket uses to figure out when a transmission stream has ended. This also means that any variables that are being sent as zero bytes need to be shifted (say +1, for example) and evaluated in Flash accordingly, or else Flash will kill the transmission there 
}
 

Flash:

Code:

//establish connection to get data
serialServer = new XMLSocket();
serialServer.connect("127.0.0.1",9001);
serialServer.onConnect = function(success){
trace("the client connected to the server");
}
serialServer.onClose = function(){
trace("the client disconnected :(");
}
serialServer.onData = gotSomething;
//what to do with data
function gotSomething(datar){
parts = datar.split(",");
//here the comma is treated as the separation between variables. Anything (except for a zero byte) can be used, so long as the code in processing is changed as well
speech = parts[0];
speech2 = parts[1];
}
 

Hooray! Hopefully this will be of some help.

Has anyone tried this recently? I had this working a year or two back for a project, but now i need it for another, and Flash 8 connects, but the XMLSocket/onData and XMLSocket.onXML event handlers don't seem to receive anything - even using the code listed below

thanks for the answer - i managed to get the XMLSocket to receive stuff in the end.

My main concern with using the Processing Server object is that if a client disconnects, the whole Processing applet falls over. I'll probably write something a bit more robust in Java instead, maybe integrate it in the processing application.

i've used OSC - with MaxMSP & Flash - a fair while ago - worked fine, no hiccups in a performance using it. MaxMSP moved on though and got it's own networking stuff - not checked that out yet properly.

Hi, i have a problem to make a caroussel menu icons spin with processing,processing conect and sent data,but i dont know the changes to make the camera act as a mouse,to spin the around the carousel,heres´s the code

<--------------PROCESSING------------------------->

import processing.net.*;

int port = 9001;
Server myServer;
byte zero = 0;
int total = 7;
int total2 = 2;
import JMyron.*;

JMyron m;//a camera object

void setup(){
 size(320,240);
 m = new JMyron();//make a new instance of the object
 m.start(width,height);//start a capture at 320x240
 m.trackColor(0,0,200,200);//R, G, B, and range of similarity
 m.minDensity(100); //minimum pixels in the glob required to result in a box
 println("Myron " + m.version());
 noFill();
 myServer = new Server(this,port);
}

void draw(){
 m.update();//update the camera view
 drawCamera();//draw the camera to the screen
 int[][] b = m.globBoxes();//get the center points
 int xi=1000, yi=1000, xf=0, yf=0;
 int xc, yc;  

 //draw the boxes
 stroke(255,0,0);
 for(int i=0;i<b.length;i++){
   if(b[i][0]<xi)
     xi = b[i][0];
   if(b[i][1]<yi)
     yi = b[i][1];

   if(b[i][0]+b[i][2]>xf)
     xf = b[i][0]+b[i][2];

   if(b[i][1]+b[i][3]>yf)
     yf = b[i][1]+b[i][3];

  // rect( b[i][0] , b[i][1] , b[i][2] , b[i][3]);
 }
if(b.length > 0)
{   rect( xi , yi , xf-xi , yf-yi);

 xc = xi + ( xf-xi)/2;
 yc = yi + ( yf-yi)/2;
 myServer.write( xc +","+ yc);
 myServer.write(zero);
 }
 
}

void drawCamera(){
 int[] img = m.image(); //get the normal image of the camera
 loadPixels();
 for(int i=0;i<width*height;i++){ //loop through all the pixels
   pixels[i] = img[i]; //draw each pixel to the screen
 }
 updatePixels();

}

void mousePressed(){
 m.settings();//click the window to get the settings
}

public void stop(){
 m.stop();//stop the object
 super.stop();
}


<-----------------------FLASH CODE---------------------->
<code>
function mover()
{
//(WHERE I GIVE THE ATTRIBUTES FOR PROCESSING??)

this._x = Math.cos(this.angle) * radiusX + centerX;  

this._y = Math.sin(this.angle) * radiusY +  centerY;

var s = (this._y - perspective) /(centerY+radiusY-perspective);

this._xscale = this._yscale = s*100;

this.angle += this._parent.speed;

this.swapDepths(Math.round(this._xscale) + 100);
}

this.onMouseMove = function()
{

speed = (this._xmouse-centerX)/2500;
}
</code>
I hope somebody give me a hand,i have read all sections and topics and didn´t find(or not see) a solution...just need to
know how to give the attributes ( processins vars)to a camera be my mouse!
Thank you
Regards

Hi guys,

Nice post.
Any way i can talk from Flash back to the Java (processing) server ?

Hi, I was reading about this matter and i used the code from fadore and yes the connection its ok, the output in flash said "the client connected to the server"  but dont send any data??? somebody know how do it?
