STEP 1: Let's add the starting line and allow objects to move on and off the stage!

Disable walls will allow objects, like car sprites, to enter and leave the stage.

  • Add a Rectangle and name it start_ground.
  • Position the rectangle at (0, -250). Make it 500 pixels wide and 50 pixels high. Make the color "lightgreen".
  • Go to and drag Disable Walls into the program.

To navigate the page using the TAB key, first press ESC to exit the code editor.
