I cannot see my way to sorting an array of points using a simple float comparison. Here’s the essence of what I’m seeking to do: import java.util.Collections; void setup(){ ArrayList<Point> points = new ArrayList(); PVector p0 = new PVector(100, -100); PVector p1 = new PVector(-130, 65); …

Can you post the rest of your sketch for the second example? From what you’ve posted so far, the one thing that stands out to me is it feels a little weird for the Point class to also be a Comparator for Point- I would expect Point to be a Comparable, and a Comparator to be a separact class. But I …

Thank you as always GoToLoop! The original code example now works with a new understanding of comparators gleaned from your examples (and some doc research). import java.util.Comparator; void setup(){ ArrayList<PVector> points = new ArrayList(); PVector p0 = new PVector(100, -100); PVector …
