// Play a sound when we hit an object with a big velocity
var audio: AudioSource;
function Start() {
	audio = GetComponent.<AudioSource>();
}
function OnCollisionEnter(collision: Collision) {
	if (collision.relativeVelocity.magnitude > 2)
		audio.Play();
}

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
	AudioSource audio;
 
	void Start() {
		audio = GetComponent<AudioSource>();
	}
 
    void OnCollisionEnter(Collision collision) {
        if (collision.relativeVelocity.magnitude > 2)
            audio.Play();
