Hi Emilio,
About snap an object to a predefined position, just set the loc (or
another property as the topLeft, the bottom, etc.) of this object
when the user releases the mouse.
As for drag and drop, you might be interested by my How-To stack #010

(It's the same way of doing with objects)

Hi all,
I want to create a simple screen that allows a user to drag a
button from the center of the screen to one of three hotspots and
then run some function.
The problem I am having is the interaction between object that I
use to define the hotspot (an image) and the button I want the user
to move around. I thought it would be best to use an image with a
fixed size to define a portion of the card to accept a "drop".
However, the messages don't seem to move as I would expect. That
is, i can drag the button around no problem, but to detect whether
some portion of the button is over the image is proving odd. For
example, you I release the mouse outside the image object *on
mouseUp* fires correctly and *is within* correctly returns false.
However, when I drag the button over the image and release while
over the image, *on mouseUp* doesn't fire at all. The
functionality I'm looking to create is a snap-to mechanism that
detects whether the button is over any part of the image and then
snap the button to a position relative to the image. The end
result is that I need to know which buttons were dragged into the
three hot zones so I can store that information.
Any suggestions is greatly appreciated.
Cheers,
Emilio
