Determining left or right movement in a mouseMove handler

[Mark Schonewille]

Hoping I didn't mix up the x's and y's, I believe the script you need 
looks like this:

local myOldX,myOldY
on mouseMove theNewX,theNewY
   if myOldX < theNewX then put
     "right" into myMovement
   else
     put "left" into myMoveMent
   end if
   if myOldY > myNewY then put
     "down" into myMoveMent
   else
     put "up" into myMoveMent
   end if
   // do something with right, left,
   // up and down here.
   put theNewX into myOldX
   put theNewY into myOldY
   pass mouseMove
end mouseMove


Kind regards,
