STEP 13: Something's not right about these cars! Let's fix that and start moving our turtle.

  • From the toolkit, drag Disable Walls to the bottom of the program. It should not be indented!
  • Click Run. Do the cars still bounce off the walls?

stage.disable_all_walls() allows the cars to continue on their roads and stops them from bouncing off the walls.
