hi, where you find that?

first you need to learn how to post code here at the forum,  
-a- it should be running ( complete ) code what can be copy pasted to PDE

-b- it should be formatted, in PDE using [ctrl][t]  
here using the `</> Preformatted text ` button from the forum editor

* * *

for a beginner also use short examples from  
[https://processing.org/reference/](https://processing.org/reference/)  
or examples or tutorials  
not like that.

* * *

i rewrite it to a ?similar? but readable and functional code

```auto
int floors = 60;
float pointAngle = 360.0/floors;
float x, y,radius = 100, off = 0; // later play with different off settings

void setup() {
  size(300, 300);
  stroke(0, 0, 100);
  strokeWeight(2);
}

void draw() {
  background(200, 200, 0);
  translate(width/2, height/2);
  for (float angle = 0; angle < 360.0; angle += pointAngle) {
    x = cos(radians(angle)) * radius;
    y = sin(radians(angle)) * radius;
    line(x/2, y/2+off, x+off, y);
  }
}

```

now you try again to understand
