Hi all,

I found out that maxlink can only send a stream of numbers and not any entire arrays. In stead I would like to send each number of an array from max rather quickly after each other. How do I make a function that places incoming numbers at certain positions in an array? i.e I have 3 numbers: 4, 6, 8, comming in from max, and I want to write them into position 0, 1, 2, in an array in processing. I looked up arrays in the reference:

int[] numbers = new int[3];

int[] numbers = { 90, 150, 30 };

numbers[0] = 90;
numbers[1] = 150;
numbers[2] = 30;

- it looks like a tedious process to individually have to position each incoming number from max into an array. How do I automize this process?

Thank you,
GR

ok, I tried to include your suggestion above in my code. I get an ArrayIndexOutOfBoundException - here's my code:


import maxlink.*;

MaxLink link = new MaxLink(this, "message_board"); // get all messages from max link object - refer to object name
public float num1, num2, num3, num4, num5;

public int out1, out2, out3;
int posX, posY;

String oldMessage = "";
String message = "";
int messageCount = 0;
// array to contain numbers an array sent from max
float [] numbers = new float[0];
float recievedNumber;


void setup() {
 size(300,300);
 background(20);
 // inlets from max to processing
 link.declareInlet("num1");
 link.declareInlet("num2");
 link.declareInlet("num3");
 link.declareInlet("num4");
 //link.declareInlet("numbers");
 link.declareInlet("recievedNumber");
 // array from max
 //recievedNumber is what you get from maxlink
 numbers=append(numbers,recievedNumber);
 
}

void draw() {
 drawMessage();

 stroke(250);
 line(20, 300, 20, num1);
 stroke(250);
 line(30, 300, 30, num2);
 stroke(250);
 line(40, 300, 40, num3);
 
 ellipseColor();
 mouseAction();
 arrayFromMax();

}



// this method must be public - if a message number is different than previous, then notice it!
public void setMessage(String newMessage) {
 messageCount++;
 link.output(messageCount);
 oldMessage = message;
 message = newMessage;
}

void drawMessage() {
 background(20);

 if (oldMessage != "") text("previous message: " + oldMessage, 37, 80);
}

// these two circles will be white if box is checked in max and grey otherwise
void ellipseColor() {
 if(num4==1) {
   fill(255);
   noStroke();
   ellipse(200, 30, 20, 20);
 } else {
   fill(100);
   noStroke();
   ellipse(200, 30, 20, 20);
 }

if(num5==1) {
   fill(255);
   noStroke();
   ellipse(200, 57, 20, 20);
 } else {
   fill(100);
   noStroke();
   ellipse(200, 57, 20, 20);
 }
 
}

// mouseClick and x/y coordinates will be sent to maxlink object in max
void mouseAction() {
 posX=mouseX;
 posY=mouseY;
 
 if(mousePressed) {
   out1=1;
 } else {
  out1=0;
 }
 link.output(1,out1);
 
 noStroke();
 fill(255);
 rect(posX, posY, 20, 20);
 //println("posX");
 out2=posX;
 out3=posY;
 link.output(2,out2);
 link.output(3,out3);
}

void arrayFromMax() {
 fill(255);
 line(numbers[0], 50, numbers[1], 50);
}

hmm, now I am just screwing around, but it seems like I can't really get to the data ... on the max side I send the array through the max object iter (iterates through the array and sends one number at a time to processing ...

Here's the code:

import maxlink.*;

MaxLink link = new MaxLink(this, "message_board"); // get all messages from max link object
public float num1, num2, num3, num4, num5;
public float [] numbers = new float[4];

public int out1, out2, out3;

public int flag1;

int posX, posY;

String oldMessage = "";
String message = "";
int messageCount = 0;
// array to contain numbers an array sent from max




void setup() {
 size(300,300);
 background(20);
 // inlets from max to processing
 link.declareInlet("num1");
 link.declareInlet("num2");
 link.declareInlet("num3");
 link.declareInlet("num4");
 link.declareInlet("num5");// array from max
 
 
 
 flag1 = -1;


 //recievedNumber is what you get from maxlink
 //numbers=append(numbers, recievedNumber);
 //}
 
}

void draw() {
 
 
 drawMessage();

 stroke(250);
 line(20, 300, 20, num1);
 stroke(250);
 line(30, 300, 30, num2);
 stroke(250);
 line(40, 300, 40, num3);
 

 
//  if (flag1 < 0) {
 //  flag1 = flag1 + 1;
//  }
//  if (flag1 > 3 | num5 > 300.0) {
//    flag1 = -1;
//  }

//      numbers[flag1] = num5;
//      print("array@"+flag1);
//      println(" = "+num5);


//    println("hello" + num5);

//  if(flag1 >= 0) {
//        numbers[flag1] = num5;
//        print("array@"+flag1);
//        println(" = "+num5);
//  }
 
 ellipseColor();
 mouseAction();
 arrayFromMax();
