Hello i'm trying to help a student with one of her projects, but we can't seam 
to get it to work. 

this is the procedure that she is currently using in her project
to scratch
clean
pd
fill
setpos [-366 212]
setc 84
seth 90 
fd 732
seth 180
fd 424
seth 270
fd 732
seth 0
fd 424
end

What she wants is for the page to be filled in and then be able to scratch it 
off so in the end it reveals a picture.

The fill procedure works only if it doesn't have a picture on the background, 
otherwise it only fills in a part or section of the picture but not the whole 
scene. is there anyway to fix it or is it even possible in microworlds?

  • To save an attachment to your computer, PC users should right-click (Mac users, click and hold the mouse button) on the link and then choose 'save target as' from the pop-up menu. A window will then pop up in which you can choose a location for the file.
