Constrained grab

Drinking aside, get item 2 of the loc of your target object on mouseEnter. Put it into a custom prop of that object. Write a mouseMove handler that sets the loc of the target to item 1 of the mouseLoc & "," & the property.

Subject: Constrained grab


I have a "blob" that contains this script:

on mouseDown
   grab me
end mouseDown

so I can move the "blob" around . . .

HOWEVER I want to somehow constrain the GRAB so that I can only drag the 
"blob" laterally.
