Is this the kind of thing you mean?
sync on
autocam off
position camera 0,0,-100
make object sphere 1,4
set object collision on 1
make object box 2,40,10,10
set object collision on 2
make object box 3,40,10,10
set object collision on 3
gravity#=-0.002
xspeed#=0.05
x#=-50
y#=80
position object 1,x#,y#,100
position object 2,-30,30,100
position object 3,0,0,100
do
inc x#,xspeed#
inc y#,yspeed#
inc yspeed#,gravity#
if object collision (1,0)>0
inc y#,0.5
yspeed#=yspeed#*-0.8
endif
position object 1,x#,y#,100

loop
If it is, let me know if you want me to explain it.
