It seems I'm geometry-challenged today -- I know this should be simple, but
I'm stumped:


I can draw a line object from the loc of one object to the loc of another.
But if I want to draw only in the space _between_ objects rather than
intersect them, how do I get the points for the location where a line object
would meet the edge of the other objects if drawn all the way to their
centers, as indicated by the "X"s below:



----------------- | | | button1 | | \ | ----------X------ \ \ ------X---------- | \ | | button2 | | | -----------------


Try something like this:


on mouseUp
  put item 1 of loc of button 2 - item 1 of loc of button 1 into tDeltaX
  put item 2 of loc of button 2 - item 2 of loc of button 1 into tDeltaY
  put atan2(tDeltaY, tDeltaX) into tRadianAngle
  put tRadianAngle * (180/pi) into tDegreeAngle
  put tDegreeAngle into field 1

put ((width of button 1/2) * cos(tRadianAngle)) + item 1 of loc of button 1 into tNewX
put ((height of button 1/2) * sin(tRadianAngle)) + item 2 of loc of button 1 into tNewY
set loc of graphic 1 to tNewX,tNewY
put cr & tNewX & ":" & tNewY after field 1
end mouseUp


You will need to add a buffer into tNewX and tNewY to get outside the button
