Hi,

I am pretty new to processing and I am trying to create circles evenly spaced over an entire square surface that randomly change color. I've achieved everything but the evenly spaced part. We need to keep the code relatively simple as per the requirements of our assignment in class. I've tried to use what I know (like using boolean statements and state machines) but I am failing. Here's a look at my code, could you help me out?

float r;

float g;

float b;

float a;



float diam;

float x;

float y;

int endCircle;

int len;

int spacing;


void setup() {

  size(200,200);

  background(255);

  smooth();   

}



void draw() {

  // Each time through draw(), new random

  // numbers are picked for a new ellipse.

  r = random(255);

  g = random(255);

  b = random(255);

  a = random(255);

  diam = 20;

  x = random(10,190);

  y = random(10,190);
 

  // Use values to draw an ellipse

  noStroke();

  fill(r,g,b,a);

  ellipse(x,y,diam,diam);
 
  x = x + 20;
  y = y + 20;
 
 
}

Thanks!

I am taking a college course using processing and I have an assignment due tomorrow that is just killing me. Could someone look at my code here and tell me why they think it isn't working?

Much appreciated, thanks:

void setup (){
  size(400,400);
  smooth();
  frameRate(30);
}
    if (mouseX < width/2) {
      draw ();
    background(0,30,200);
    stroke(0);
    fill(30,200,0);
    rect(0,200,400,200);
