Drag a movie according to a circle

Needed this code and I found thanks to this forum and your good explanation. Also your blog is in my favourites from now.

Thanks for share.

Well, on second thought, the difference is probably too greate between
what you want and what that other article illustrates. I wrote a new blog
entry to handle your clock hand dragging. Check it out here. :)

That's what the forums are for. :)

Okay.

Aha. Well, the startDrag() function, and its MovieClip.startDrag()
method, don't much care *where* you drag a movie clip, only *that* you drag
it. Actually, both the function and the method do allow you to constrain to
a rectangle (see the optional parameters for either).

Heh, I'm sure everyone who posts a question believes it to be urgent.
;) Let's see what we can do, here. It just happens that I recently blogged
about how to constrain to a circle. I'm not sure your need is to constrain,
per se -- it sounds as if you want to drag your movie clip on the edge of a
circle only -- but if you piece through my sample code, you'll see that the
answer to what you're after can be derived from the information presented.

Hint: you'll want to forego the if() statement and simply use the part
that sets the MovieClip._x and MovieClip._y properties to the mouse's
position.
