I'm just trying to avoid rolling my own dragging functionality. Does anyone know of any libraries out there that have a startDrag() equivalent where you can use, say, a circular radius for the drag bounds, rather than a rectangular box?
(For circular drag area) - What you need to do is:
a) Mouse_down: Store start position. Start listening to Enter_frame.
b) Enter_Frame: Check distance from mouse position of mouse to start pos (use pythagoras)
c) only move your object if the distance is less than x
d) Mouse_up: Stop listening to enterframe
