Build the "height map" of the tropical paradise of your dreams, then watch it come to life! The left and right keys change the size of your height brush; the up and down keys raise and lower the land beneath your brush; the space bar turns your height map into a picture of your island.
Our terrain generator is made from cloned sprites that each draw with the pen module. The template for this lesson is available here: https://scratch.mit.edu/projects/351654173/
