my name is Shane and i am stumped. My teacher Ms. Andrea and i are trying to
figure out how to make a turtle stop at a line it draws. How can I make it
react to a line that it go back over after it draws it. So far I've tried
using colorunder but it detects the color right away. I also tried using
programming the colors but nothing is working. Please help.
One solution would be to start detecting the color using "colorunder" *after*
you draw the line. Not right away.
If the project is not too big you can send it to
