Watch the lines go all over the place! Variables: Pen down makes the lines trace a line. Pen: erase all erases all pen markings. NOTE: If Pen Down is not working, make sure Pen: Erase All is on 0.
I started this project a few months ago, but gave up since I was not as experienced with Scratch as I am now. Now, I continued it and reshared it. Thanks to you for watching this and silver31415 for programming!
