Help Please :- Common Snapping Distance

[Logic Writer]

Hi all,

I have a lot of sprites on stage which represent magnets. All these sprites
have the same height but different widths. I want to write a program in
which when two sprites come close to each other at a specific distance they
must snap to each other.
Now my main problem is that since each sprite have different widths it is
difficult to fix a single value for the distance within which they should
snap to each other. Also it is also possible that any sprite can come close
to another sprite from any side. So the script should check for the distance
from any side. Please suggest some ways in which I can establish a common
distance between the sprites which have different widths.

Looking forward to suggestions. Thanks a lot.

Regards,
LW J

The approximate alogorithm in pseudocode:

if left edge of sprite > right edge of other sprite then
if:
sprites overlapping
OR right edge of other sprite - left edge of sprite < snap range
then
snap
end if
else <do the same in reverse for other side>

repeat for top & bottom as well as left & right. You can easily get the
edges of the sprites by checking the .rect property instead of just .loc;
you can also use .height, .width and loc together with the regpoint to get
the same values.
