Hello,

Please format your code for readability and so we can copy it easily:
https://discourse.processing.org/faq#format-your-code

Try to cut and paste your code into Processing and you will understand.

When I hover over this code I can use the copy icon that pops up in upper right.

Example:

void setup() 
	{
  size(700, 150);
  background(0);
  fill(0, 255, 0);
  textAlign(CENTER, CENTER);
  textSize(48);
  text("Please format your code. :)", width/2, height/2-10);
	}

:)
