The simplest thing to do would be to create a couple graphic objects
on top of where the students should click (over those objects) , then
set their ink to noop so they're transparent. Then you could just
stick some script into the graphics' mouseup handler.
However, if there's some need for the clickloc, you can change the
clickloc to what it is compared to the entire group by doing
something like this:
put the mouseLoc into quickLoc
add the hscroll of group "myGroup" to item 1 of quickLoc
add the vscroll of group "myGroup" to item 2 of quickLoc
Now quickLoc will hold where on the entire image they clicked... for
instance, let's say on the screen they clicked at 150,200. But if it
was scrolled 10 pixels to the left and 20 pixels down, the location
for the entire image would be 160,220. Kinda get it? Hope I didn't
confuse you too much! :)
