Andreas Schlegel has written the oscP5 library for OSC from Processing. It's definitely in the forum, try "search"...

Did someone test the osc library under 0.93/0.95 ? Here on Mac OsX (10.3.9) osc is just working under version 0.91.

hi acady,
i just did a test on osx 10.3.9 with oscP5 running processing 0095 beta and sending/receiving worked for me. i tested with processing and supercollider. is it giving you errors or does it just not work?

hm,
do you have the draw() method in your sketch?
can you post code?

Finally, i got it, now this code works in all versions. I think by going not that deep inside right now, the problem is somewhere between simpleOSCMessage and the version with the object.

//the code
import osc.*;
import oscP5.*;
// oscP5 instance for the osc communication
OscP5 oscP5;
int receiveAtPort;
int sendToPort;
String host;
String oscP5event;

void initOsc() {
       receiveAtPort = 12500;
       //sendToPort = 57120;
       sendToPort = 12000;
       host = "127.0.0.1";
       oscP5event = "oscEvent";
       oscP5 = new OscP5(
               this,
               host,
               sendToPort,
               receiveAtPort,
               oscP5event
               );
     mouseMoved();

}


void oscEvent(OscIn oscIn) {
       println("received ...");
}



void setup(){
       background(0);
       size(400, 400);  
       initOsc();

}

void draw()
{
 background(204);
 line(mouseX, 20, mouseX, 80);
}

void mouseMoved() {
OscMessage oscMsg = oscP5.newMsg("/test");
Object[] mObj;
       mObj = new Object[] {new Integer(12), new Float(34.55), "meins"};
String mousePos = str(mouseX);
oscP5.sendMsg(mousePos,mObj);
}
