I'm starting to learn how communicate with Max/MSP and Processing. I've discovered first MaxLink libraries to do it, i've tried it and i found that it is now outdated and still unsupported so i'll go out with OSC (udpsend object) and oscP5 library in Processing to do the same things. So i've tried to learn how use Processing replicating and converting some easy examples of MaxLink libraries to oscP5, in particular the "shape_sketch" one, which send from max/msp a "bang" from /drawCircle, /drawSquare, /clear message objects to generate randomly 2D shapes in Processing, but i'm still newbie and i can't understand what is not working with oscP5, because, after i click that message objects in max/msp, in Processing nothing happens.

I'm asking if Processing can see a "bang" from max (like a string?), or i have to declare it in an other way. The idea anyway is to use something that hit an ON value to "bang" an action, without use a streams of int or float values.

// declare the variable name and the setter function name

link.plug(this, "drawCircle", "/drawCircle");

link.plug(this, "drawSquare", "/drawSquare");

ellipse(random(width), random(height), r, r);

rect(random(width), random(height), w, w);

void setup() {
  size(300, 300);
  background(250);
  noStroke();
  smooth();
  OscP5 link = new OscP5(this, 8080);
 

 // declare the variable name and the setter function name
  link.plug(this, "drawCircle", "/drawCircle");
  link.plug(this, "drawSquare", "/drawSquare");
  link.plug(this, "clear", "/clear");
}

void draw() {
  // must define draw function to
  // allow accurate future drawing
}

// these methods must be public
public void drawCircle() {
  fill(0, 0, 240, 200);
  float r = random(50) + 5;
  ellipse(random(width), random(height), r, r);
}

public void drawSquare() {
  fill(50, 240, 50, 200);
  float w = random(50) + 5;
  rect(random(width), random(height), w, w);
}

public void clear() {
  background(250);
}

Hi to all,

Hi Alaghast. I have done some projects that connect Max and Processing in this way. However, I am not familiar with this syntax:

Maybe it is newer? Instead, I have implemented an oscEvent method like this

Inside the method, you can do whatever parsing is necessary for your messages. But remember, OSC is a standard requires the identifying address at the beginning. You could NOW send just a raw bang message, but you could send something like:

if (message_in.checkAddrPattern("/drawCircle") == true) {

String temp = message_in.get(0).stringValue();

}

Thank you for your answer, i didn't know oscEvent. Anyway i've solved the problem comunicating both with this method and with plug.

I find plug anyway more simple to write, i share here an example how it works with max patch example, i hope this help someone else go in stuck with it:

void setup(){
oscP5 = new OscP5(this,12000);

/* You define there with "/test" the message that come from Max,
like an object [prepend /test].
With "result" you define a name to construct a function inside Processing */

// The function must be public 
public void result(int valueA, float valueB, String valueS) {

 /*The cool thing is that you can send from [prepend /test] three message,
inside a pack object for example, that have three different "type" of values*/

 println("The three result will be: " + valueA + ", " + valueB +" ," + valueS);
}

And there a max patch example to comunicate with it:

I find plug anyway more simple to write, i share here an example how it works with max patch example, i hope this help someone else go in stuck with it:

import oscP5.*;
OscP5 oscP5;

Thank you very much!!! I've searched for it for a long time !!

I get the following error in the Processing sketch :( HELP ME PLEASE!

I get the following error in the Processing sketch :(   HELP ME PLEASE!

You have typed wrong "import", it isn't import"e" <--- This final "e" is wrong.

Just try to copy and paste to Processing sketch the code that i've previously attached.

thanks for your valuable post. Really helpful. if ever stuck with any query relating with processing of OSC you can go to 

 and know how it works and communicate in other systems.

Is it possible to do something similar in p3 on a local network?
