While you are waiting for getting help, here are some tips to improve your experience:

Code is much easier to read if posted with syntax highlighting and proper formatting.

If nobody is calling back, that usually means that your question was not well asked and hence nobody feels confident enough answering. Try to use your time to elaborate, provide details, context, more code, examples and maybe some screenshots. With enough info, someone knows the answer for sure.

Don't forget to close your thread using the command </help-thread close:1027500463647621170> when your question has been answered, thanks.

Oh thats cool

It deleted my whole message bc i added a file

Oh Well Just wait a few minutes

Here is the Code

It doesnt light up a random squares as it should do

It might something very obvious but im a begginner

Chess.pde

import java.util.Random;

final int WIDTH = 400;
final int HEIGHT = 400;
final int BLOCKX = WIDTH / 8;
final int BLOCKY = HEIGHT / 8;
 
void setup() {
  size(400, 400);
  noLoop(); 
  noStroke();
}
 
void draw() {
  for (int i = 0; i < 8; i ++) {
    for (int j = 0; j < 8; j ++) {
      if ((i + j + 1) % 2 == 0) {
        fill(255, 255, 220); // white
      } else {
        fill(63, 33, 4); // black
      }
      rect(i * BLOCKX, j * BLOCKY, (i + 1) * BLOCKX, (j + 1) * BLOCKY);     
    } 
  }
}


void mousePressed() {
  if (mousePressed) {
    Position p = new Position();
    Random r = new Random();
    p.letter = (char)(r.nextInt(8) + 'a');
    p.number = r.nextInt(8) + 1;
    p.lightUp();
  } 
}
