hello everyone,
first of all i am totally new to this. i'm a graphic designer and just recently started playing around with Processing (i know, i know, needy n0obie).
i need to make a simple grid (for now), and seeing as i have specific pixel values for the lines

but i found a post here about a grid, the sketch is far too complex for my beginner skills, so i was wondering is someone knows a simple way to draw such grid (and being able to assign the pixel values) knowing that later, if i manage to learn more i would hope to make this grid interactive somehow, making the lines fall and collapse etc)
i would REALLY appreciate any help. Thanks :)

Something like this?

Code:

int nbOfHorizontalLines = 10;
int nbOfVerticalLines = 20;

void setup()
{
  size (1000,500);
}

void draw()
{
  background (100,100,100);
  stroke(255,0,0);

  float distanceBetweenHorizontalLines = (float)height/nbOfHorizontalLines;
  float distanceBetweenVerticalLines = (float)width/nbOfVerticalLines;

  for(int i = 0; i < nbOfHorizontalLines; i++)
  {
    line(0, i*distanceBetweenHorizontalLines, width, i*distanceBetweenHorizontalLines);

  }

  for(int i = 0; i < nbOfVerticalLines; i++)
  {
    line (i*distanceBetweenVerticalLines,0,i*distanceBetweenVerticalLines, height);
  }
}
