Press the green flag, then click three points to have the project create a curve between them.
This project was pretty much just a test to see if I could make a Bézier curve on scratch. The script is based entirely on the animations for it I saw on the wikipedia page like this one https://upload.wikimedia.org/wikipedia/commons/thumb/3/3d/B%C3%A9zier_2_big.gif/240px-B%C3%A9zier_2_big.gif So far this only really makes Quadratic Bézier curves, any higher order ones appear to use recursion. If someone could tell me how to recursively program something on scratch that would be wonderful.
