This video explains how clones let one sprite make many temporary copies of itself.

  1. Why use clones instead of drawing many separate sprites by hand?
  2. What happens to a clone when it's deleted?
  3. What kind of project (raindrops, enemies, confetti) would clones be useful for?

Quick work-a-long

Words to know: clone, create clone, delete this clone.

Try it: Add a "create clone of myself" block inside a loop and watch how many copies of the sprite appear.
