There are any number of ways to do this thing. Try giving this script to the
object you want to move:
local DisX, DisYlocal GridSize = 20-- if grid uses different sizes for X and Y,
make GridSizeX and GridSizeYlocal OriginGridX = 10local OriginGridY = 10
on mouseDown send "TrackDaMouse" to meend mouseDown
on TrackDaMouse put the mouseLoc into Fred put GridSize * ((item 1 of Fred -
OriginGridX) div GridSize) + OriginGridX into DisX put GridSize * ((item 2 of
Fred - OriginGridY) div GridSize) + OriginGridY into DisY set the loc of me to
Fred if the mouse is down then send "TrackDaMouse" to me in 20 msec else
move me to (DisX, DisY) in .5 seconds end ifend TrackDaMouse
