Play Audio Clip sound

I have a “point” prefab. This prefab has a sound and i put it in a Audio Clip for reuse. But the Unity generate this error…

MissingComponentException: There is no ‘AudioSource’ attached to Point… there is my code…

using UnityEngine;
using System.Collections;

[RequireComponent(typeof(AudioSource))]
public class PointScript : MonoBehaviour {

	public int value;

	public AudioClip audioPoint;

	void OnTriggerEnter2D(Collider2D other) {
		PlayerScript playerScript;
		if( playerScript = other.GetComponent<PlayerScript> ()){
			playerScript.addScore (value);
			die ();
		}
	}

	public void die(){
		audio.PlayOneShot(audioPoint);
		Destroy (gameObject);
	}


}

You need to add an audio source to whatever object is playing the sound. Highlight the game object/prefab and click Component/Audio/Audio Source.

audio.PlayOneShot(audioPoint);
Destroy (gameObject);

it’s been destroyed when it just started singing!
