I use global or local variables 
for the *similar* tasks, I do not
write the games.

For example:

integer obj_1_x, obj_1_y
integer obj_2_x, obj_2_y
------- and so on

Or

global sequence things
things={{x1,y1},{x2,y2},{x3,y3},{0,0},{0,0},{0,0}}
------- and so on

Then you can just use things[1][1] for
not fixed x coordinate of the 1st thing
and things[1][2] for not fixed y coordinate
of the 1st thing.

You drag this thing with mouse and reassign
the current mouse's coordinates to
that your variable. These variables are
global or local, not private, so they keep
new coordinates outside procedures and
functions.

Local - for include file's procedures and
functions (or for main file's procedures
and functions).
Global - for all after the point of
declaration.
(refman.doc 2.4.2 Scope section)

If you then drag the box full of the things,
you just add box's coordinates to all
things' coordinates.

If me understand your question well,
this method must work.
