OSCp5 Help!
Jan 17th, 2008, 5:35pm  
Hey there

I am currently working on a project which uses max/msp to detect pitches and then uses the OSCp5 library in order to receive these pitches from max. The problem i am having at the moment is that i cant seem to beable to use the message sent in any way...EG i get the values into my comment box ok but when i try to implement them i cant seem to use them...im looking to beable to say //if(new value >47.8 && new value < 48.2);

Obviuosly not like that but that overall idea. I probably have made a stupid mistake somewhere but any help would be much appreciated here is my sketch:

import oscP5.*;
import netP5.*;

OscP5 oscP5;
NetAddress myBroadcastLocation;

Notes start,stop;
Notes [] n;
PImage bg;
int a;

PFont font;

void setup()
{
 size(1440,900);
 frameRate(30);
 /* start oscP5, listening for incoming messages at port 12000 */
 oscP5 = new OscP5(this,12000);
 
 /* myRemoteLocation is a NetAddress. a NetAddress takes 2 parameters,
  * an ip address and a port number. myRemoteLocation is used as parameter in
  * oscP5.send() when sending osc packets to another computer, device,
  * application. usage see below. for testing purposes the listening port
  * and the port of the remote location address are the same, hence you will
  * send messages back to this sketch.
  */
 myBroadcastLocation = new NetAddress("143.117.78.67",12000);

  start = new Notes(200,500);
 n = new Notes[1];
 
 // The background image must be the same size as the parameters
 // into the size() method. In this program, the size of "milan_rubbish.jpg"
 // is 200 x 200 pixels.
 bg = loadImage("LCM-SCALES.jpg");
 
 font = loadFont("Maestro-96.vlw");
 textFont(font);
 fill(300);
}

void draw()
{
 
  background(bg);
  start.draw();

}

class Notes{
float x1,y1,x2,y2;
Notes(float x, float y) {
 x1 = x;
 y1 = y;

}


void draw() {
fill(0);
  text("q",x1,y1);
  textSize(120);
}

}


/* incoming osc message are forwarded to the oscEvent method. */
void oscEvent(OscMessage theOscMessage) {
 /* get and print the address pattern and the typetag of the received OscMessage */
 println("### received an osc message with addrpattern "+theOscMessage.addrPattern()+" and typetag "+theOscMessage.typetag());
 theOscMessage.print();
}



thanks

Reply #2 - Jan 18th, 2008, 4:17pm  
assuming your address pattern is /sinusoids and it has one float as argument (reading from your max patch), then you could do the following:

(1) in oscEvent()
Code:

void oscEvent(OscMessage theOscMessage) { 
  if(theOscMessage.checkAddrPattern("/sinusoids")==true) {
    float f = theOscMessage.get(0).floatValue();
    if(f>47.8 && f< 48.2) {
	// do something.
    }
  }
}


(2) or you can use oscP5.plug()
in setup() after you have created oscP5, add
Code:

oscP5.plug(this,"sinusoids","/sinusoids");

then add the following function to your code
Code:

public void sinusoids(float theValue) {
  if(theValue>47.8 && theValue< 48.2) {
    // do soemthing.
  }
}


you can also check the examples oscPlug or oscParsing
best,
andi
