Hi there. Here's an easy way to do that.
autocam off
sync on
for i= 1 to 5
make object sphere i,5
position object i,10*i,0,0
next i
position camera 20,0,-70
point camera 20,0,0
a#=1
do
set cursor 0,0:print "SELECT WITH MOUSE MOVE WITH UP/DOWN KEY"
if mouseclick()
for i= 1 to 5
color object i,rgb(255,255,255)
if pick object(mousex(),mousey(),i,i) then a#=i
next i
endif
if object exist (a#) then color object a#,rgb(255,0,0)
if upkey() then move object up a#,0.01
if downkey() then move object down a#,0.01
sync
loop
Cheers.
