how to make a billiard table

[hain]

i'm a beginner.like the topic,I want to make a billiard game.But i found i don't know how to make a billiard table.
how to make Friction on the body's surface.As I understood,Collision will happen between two or more bodys.But the billiard balls are moved up the table always.
how to simulate them?

You need to use a specially configured constraint to simulate the rolling friction between the table and the balls. See the Tank demo for an example.
