processing and SC3 via oscP5
May 12th, 2005, 11:34am  
Hi,
I just started with processing, and am attempting to communicate with SC3. I can send messages OK, (
that is

println("you have received a message "+
               oscIn.getAddrPattern()+
               "   argument 2 = "+arg2+"   argument 3 = "+arg3
        )Wink

works, and the args+message are printed out on the screen.
However trying to create a shape object, such as a small rectangle fails (that is, nothing happens). I am just attempting to use the oscP5_receive.pde straight out of the box. The SC3 code which sends three integers to pass as values to fillrect(int, int, int) is below. Could someone please explain to me why this fails, and what I may do to fix it?

sincerely,
vesa.

///////////////////////////////
/*SC3 code*/
(

var process, r;
process = Server.new("aServer", NetAddr("localhost", 12000));

r = Routine.new({
     //5.wait;
     5.do({arg a;
           process.sendMsg("/test", 30, 20, 55);
           1.wait;
           });
     1.wait;
     "done".postln;
});
SystemClock.play(r);
)

hi vesa,

try this. worked for me with your sc script. sending the 3 integers will fill the frame with the 3 integers as rgb values.

import oscP5.*;

OscP5 oscP5;
int receiveAtPort;
int sendToPort;
String host;
String oscP5event;

void initOsc() {
       receiveAtPort = 12000;
       sendToPort = 57120;
       host = "127.0.0.1";
       oscP5event = "oscEvent";
       oscP5 = new OscP5(
               this,
               host,
               sendToPort,
               receiveAtPort,
               oscP5event
               );
}


void oscEvent(OscIn oscIn) {
       println("received ...");
       if(oscIn.checkAddrPattern("/test")) {
         int r = oscIn.getInt(0);
         int g = oscIn.getInt(1);
         int b = oscIn.getInt(2);
         fillrect(r,g,b);
       }
}

void fillrect(int theR, int theG, int theB) {
 fill(theR,theG,theB);
 rect(0,0,400,400);
}


void setup(){
       size(400, 400);
       background(255);
       initOsc();
}

void draw() {
}

i'm a newbie and i've downloaded a vvvv patch that communicates with processing via osc to make blobtracking. the problem is in the sketch:

i get an error on oscIn.getDataList().size()  ---> no accessible method found...what is the problem? isn't it a correct method?

thank you

Pietro

hi piede828,
you are probably using the new version of oscP5. i made quite a few syntax changes to this version. to get the size of the data list which is the list of arguments sent to oscP5 try using the following method in your sketch

void oscEvent(OscMessage theOscMessage) {
 println(theOscMessage.arguments().length);
}

which will give you the size of the arguments (the data list). the return type of theOscMessage.arguments() is of type Object[]  

best,
andi
