Re: FLASH: drag and drop with a PIVOT point

[Gregg Caines]

There might be some kind of way to do it with some crazy algebra

but I think if I were you, I'd do it with minimal actionscript:


Create a movie clip that contains the needle arm in its start position

and tween it until it's at it's last position.  Put a stop action in the

first frame and then put that clip on the main stage where you would

want the needle arm to go.


Next create a bunch of invisible buttons along the needle's path.  In

the 'on dragover' event of those buttons target the needle MC and tell

it to gotoandstop at the frame that would best show where the needle

should be at that time.  The quality of the drag effect will be higher if

you have a high number of frames in your MC and a high number of

invisible buttons on your stage.


If you want, you can even add some actionscript to ensure that the

user goes from the start to the end in the correct sequence (rather than

dragging over an invisible button in the middle and skipping to the

middle of the movie clip).
