Code not running

I am glad to hear that.

And welcome to the forum, great to have you here!

Example 1

here is an example WITHOUT setup(), in so called static mode

size(640, 360);  // Size should be the first statement

float y = 180;

background(0, 255, 0);  // Set the background to Green

line(0, y,width, y);
line(100, y+66,width, y+66);

Example 2

and a complex Sketch with setup() and draw() which is a dynamic Sketch:



float y = 180;

// The statements in the setup() function
// run once when the program begins
void setup() {
  size(640, 360);  // Size should be the first statement in setup()
  stroke(255);     // Set stroke color to white
}

// The draw() function runs on and on
void draw() {
  background(0);  // Set the background to black

  line(0, y, width, y);
  y = y - 1;
  if (y < 0) {
    y = height;
  }
}

Warm regards,

Chrisir
