sound when bouncing

how do I make a rigidbody object with the bouncy material set on its collider play a noise every time it bounces? where would I do this or is there a specific function such as rigidbody.hit I can call for that?

recommand unity help

OnCollisionEnter

or

OnTriggerEnter

the help section does provide a working code for that

Collider.OnCollisionEnter

in short you need the following script attached to your gameobject and also a sound attached to the same gameobject.

function OnCollisionEnter(collision : Collision) {

 audio.Play();
}
