Try this

1. size(121, 121);
2. rect(0, 0, 40, 40);
3. for(int x = 0; x < width; x+=40) {
4.   for ( int y = 0; y < height; y+=40) {
5.      pushMatrix();
6.      translate(x, y);
7.      rect(0, 0, 40, 40);
8.      popMatrix();
9.    }
10. }

The translate is cummaltive so it is neccessary to save the transformation matrix before drawing each rect and then resetting after

Those transformations are cumulative. Use resetMatrix() @ each end of loop iteration round:

size(121, 121);

final byte DIM = 40;

for (int x = 0; x < width; x += DIM)
  for ( int y = 0; y < height; y += DIM) {
    translate(x, y);
    rect(0, 0, DIM, DIM);
    resetMatrix();
  }

It is better to practice use push/pop matrix rather than reset matrix as it gives you greater control over drawings especially when you have shapes made from several rectangles/ellipses etc.

In my understanding, push/popMatrix() is for complex deep transformation layers,
which need to return to a previous modified matrix state rather than the default matrix.
Otherwise, it's just a waste of key typing, performance execution and redundancy, in my opinion! 

In your version, all that pushMatrix() is doing is saving the default matrix.
And popMatrix() is recovering that default matrix again.
I don't see much logic on that, since we already have resetMatrix() available!

I believe more than 90% of usage of push/popMatrix() examples I've seen so far,
a simple resetMatrix() would be enough!
Even none of them at all, since canvas matrix is reset after each draw() calls anyways!

wow great thanx for the fast reply...I'll try it in the rest of my code!
Probably see you later ;)

ok... the rectangle works fine...but what I want to do is a little more complex...
In every rectangle there should be a little drawing of connecting points...
But with this translate() every little drawing is layered on each other and copied in every square...

this is the code I have so far (please don't laugh :) I'm trying ):

really hope you can help! I really want to finish this !

It's full of mistakes I guess...but I want to learn!

You are right it is full of mistakes but don't worry. All programmers no matter how skilled have made the same sort of mistakes during their learning process.

Here are my comments.

• In your code you just have 1 cell but actually you want 9 cells. I have created a 3x3 array of cells the idea is that each cell will draw its own pattern.
• In your code the loading of the numbers was done in the display code of the cell. This is not desirable because it will be repeated everytime we draw a cell. I have moved this to setup and use each line in turn when a cell is created (line 11)
• When a cell is created the x,y attributes are now set to the top-left pixel coordinates were the cell is to be drawn
• the cell display will save the current matrix (pushMatrix) then translate the drawing to (x,y) - see previous comment - which means all the drawing code will be inside a rectangle (0,0)-(40,40) for ALL cells, then finally restore the matrix with popMatrix
  
• when the cell is created the a and b arrays are set according to the single line of numbers passed as a string. I have not altered all the if statments because I am not sure what the pattern for each cell is supposed to be, at the moment thereoutput is obviously not what you want but we are getting there.

THANKS ALOT QUARKS!!!

This really really helps me! I can go further now!
The code you gave was almost right for the result I was looking for!
Just changed a little thing and then it was fine! (commented it)

void display() {
    pushMatrix();
    translate(x, y);
    stroke(0);
    noFill();
    rect(0, 0, w, h);
//    translate(x, y);
//    rect(x, y, w, h);
          line ( xgrid[0], ygrid[0], a[0], b[0] );
          line ( xgrid[1], ygrid[0], a[1], b[1] );
          line ( xgrid[2], ygrid[0], a[2], b[2] );
          line ( xgrid[0], ygrid[1], a[3], b[3] );
          line ( xgrid[1], ygrid[1], a[4], b[4] );
          line ( xgrid[2], ygrid[1], a[5], b[5] );
          line ( xgrid[0], ygrid[2], a[6], b[6] );
          line ( xgrid[1], ygrid[2], a[7], b[7] );
          line ( xgrid[2], ygrid[2], a[8], b[8] );
    popMatrix();
  }
}

Thanks alot!!!

Well spotted on the extra lines - I have corrected the code I posted because it might help others. Good luck with the project.

Hello again,

This time I added 9 more lines of data (that makes 18 lines), and I thought that I just had to adjust the cols and rows number, but it give a blank result...as there are 18 lines I was thinking cols = 3 and rows = 6 as 3 * 6 = 18, but it doesn't work. Or maybe I just don't understand 2D arrays?

What I really wanted to do was cols = width and rows = height, as i want to ad alot of string lines .

Ow yeah: I changed the previous code a bit: I changed the sudCell  into cols  and rows

The code:

Cell[][] cells;
String[] numbers;
int cols = 3;
int rows = 6;

void setup() {
  size(240, 120);
  numbers = loadStrings("numbers.txt");
  cells = new Cell[cols][rows] ;
  int cn = 0;
  for(int i = 0; i < cols; i++) {
    for(int j = 0; j < rows; j++) {
    cells[j][i]  = new Cell(j*40 , i*40 , 40, 40, numbers[cn]);
    cn++;
     }
  }
  noLoop();
}

void draw() {
  background(255);
  for (int i = 0; i < cols; i++) {
    for (int j = 0; j < rows; j++) {
    cells[j][i] .display();
    }
  }
}



data:
4 9 7 1 5 3 6 2 8
2 1 3 8 9 6 4 5 7
8 6 5 4 2 7 3 9 1
7 4 9 2 6 1 3 8 5
5 6 8 3 7 4 1 2 9
2 1 3 9 5 8 7 4 6
5 3 6 9 7 2 8 1 4
7 4 2 6 8 1 9 3 5
1 8 9 5 3 4 6 7 2
6 3 2 4 8 7 5 1 9
7 8 1 5 9 6 2 4 3
9 4 5 2 1 3 8 7 6
8 6 4 7 5 1 2 9 3
3 5 2 9 6 8 1 7 4
7 9 1 3 2 4 6 5 8
9 4 5 1 7 6 3 2 8
6 3 7 8 2 5 4 1 9
1 8 2 4 3 9 5 6 7

When I run this it says ArrayIndexOutOfBoundsException: 3
and I don't understand why...

Thanks!

This post here is just to publish the current state of the total overhaul I'm doing to your previous code!
Only thing left is to define a "real" useful class Cell to represent the data of 1 cell unit:

// http://forum.processing.org/topic/translate-in-a-for-loop

final static String FILE_NAME = "numbers.txt";
final static color  BG = -1, FG = #004080;
final static short  GRID = 010, DIM = 0140, MARGIN = 010; 

final static byte[] posX = {
  MARGIN, DIM>>1, DIM - MARGIN
}
, posY = posX.clone();

final static int POS_LEN = posX.length;

byte[] endX, endY;

// JAVA2D, P2D, P3D, OPENGL
final static String ENGINE = JAVA2D;

void setup() {
  size(GRID*DIM + 1, GRID*DIM + 1, ENGINE);
  noLoop();
  smooth();

  noFill();
  stroke(FG);
  background(BG);

  createCellLines();
}

void createCellLines() {
  final String[] numbers = loadStrings(FILE_NAME);
  final int NUM_ROWS = numbers.length;
  println(numbers);

  endX = new byte[NUM_ROWS];
  endY = new byte[NUM_ROWS];

  for (int row = 0; row < NUM_ROWS; row++) {
    setLineCoords( int(split(numbers[row], ' ')) );
    renderLineCoords(NUM_ROWS);
  }
}

void setLineCoords(final int[] elements) {
  final int NUM_COLS = elements.length;

  for (int col = 0; col != NUM_COLS; col++)
    for (int x = 0, y = 0, value = NUM_COLS; value != 0;) {
      if (elements[col] == value--) {
        endX[col] = posX[x];
        endY[col] = posY[y];
        break;
      }

      y += (x = (x+1) % POS_LEN) == 0 ? 1:0;
    }
}

void renderLineCoords(final int NUM_COLS) {
  /*
  for (int i = 0; i < width; i += DIM)
   for (int j = 0; j < height; j += DIM, resetMatrix()) {
   translate(i, j);
   */

  rect(0, 0, DIM, DIM);

  for (int x = 0, y = 0, col = 0; col != NUM_COLS; col++) {
    line(posX[x], posY[y], endX[col], endY[col]);
    y += (x = (x+1) % POS_LEN) == 0 ? 1:0;
  }
  //}
}

A 2D array is an array of arrays - the important thing is not to get the idexes mixed which is what you have done in line 13  which should be

cells[i][j]  = new Cell(j*40 , i*40 , 40, 40, numbers[cn]);

1. Cell[][] cells;
2. String[] numbers;
3. int cols = 3;
4. int rows = 6;
5. 
   
6. void setup() {
7.   size(240, 120);
8.   numbers = loadStrings("numbers.txt");
9.   cells = new Cell[cols][rows] ;
10.   int cn = 0;
11.   for(int i = 0; i < cols; i++) {
12.     for(int j = 0; j < rows; j++) {
13.     cells[j][i]  = new Cell(j*40 , i*40 , 40, 40, numbers[cn]);
14.     cn++;
15.      }
16.   }
17.   noLoop();
18. }

great!!
Thanx everybody!!
