Here's some code to show you how you can minimise the amount an object bounces:
` switch ground plane on and start physics
phy set ground plane 1
phy start
` set program properties
autocam off
sync on
sync rate 60
color backdrop 0
` make a new material and set resitution to 0
phy make material 1, "no bounce"
phy set material restitution 1, 0.0
phy build material 1
` make a sphere and give it the material
make object sphere 1, 1
position object 1, 0, 10, 0
phy make rigid body dynamic sphere 1, 1
` position camera
position camera 0, 5, -15
` main loop
do
phy update
sync
loop
