Getting audio to play on collision

Question

I'm fairly new to Unity 3D and game programming (high school class so few months of slow pace and self-teaching under my belt). I tried to "make" a game outside of the classroom( um its TornadoTwin's Worminator Tutorial game except I wanted to tweak it a little bit to make it my own)...and it isn't WORKING If you haven't seen the tutorials then just know that turrets and the worm shoot a sphere from the spawnPoint in front of their head tagged as fireBall and/or wormProjectile. It has a Sphere Collider and has isTrigger checked as well as a rigid body. I am trying to get an audio clip (a crackling fire sound) to play when the turrets get destroyed by my worm's fireball. Note: the OnFire script has // b/c it kept giving me compiler errors, they weren't working, etc. That script is also is a little jumbled so not everything is connected. Some of it is there b/c I know it can get audio to play but don't know how to use them/slash wouldn't work with the function. Here are my scripts: TurrentCollision (JavaScript)

 var explosion: Transform;
 
 (added separately from TornadoTwins for audio to work)
 
 var gotHit: AudioClip;
 
 function OnTriggerEnter( hit : Collider )   
 {
 if(hit.gameObject.tag == "wormProjectile")
 {
 
 Destroy(hit.gameObject);
 
 var exp = Instantiate(explosion, gameObject.transform.position, Quaternion.identity);
 
 (me/separate from Tornado)
 
 audio.PlayOneShot(gotHit);
 
 Destroy(gameObject);
 }
 }
 
 OnFire (JavaScript) (other attempt b4 I realized I could just use the Turret Collission Script)
 
 var fire: AudioClip;
 
 function OnTriggerEnter( hit : Collider) 
 {
 if(hit.gameObject.tag == "fireBall")
 {
 audio.PlayOneShot(fire);
 }
 }
 // Play impact audio clip when colliding with something
 //var impact : AudioClip;
 
 <p>//function OnCollisionEnter (collision : Collision) </p>
 
 <p>//{
 //if(collision.gameObject.tag =="wormProjectile")</p>
 
 <p>//{</p>
 
 <p>//for (var impact : ContactPoint in collision.contacts) </p>
 
 <p>//{</p>
 
 <p>//audio.PlayOneShot(fire);
 //audio.Play();
 //}
 //}
 //}</p>
 
 <p>//{
 //var impact = true;
 //audio.Play();
 //audio.PlayOneShot(fire);
 //function OnTriggerEnter( hit : Collider) 
 //{
 //if(hit.gameObject.tag == "wormProjectile")
 //{
 //  audio.PlayOneShot(impact); 
 //}</p>
 
 <p>//}</p>

I figured it out! =D
Turret Collision:

var explosion: Transform; var expSound: AudioClip; var fireSound : AudioClip;

function OnTriggerEnter( hit : Collider)
{

     if(hit.gameObject.tag == "wormProjectile")
     {
         AudioSource.PlayClipAtPoint(fireSound, Vector3 (1.995417,2.282711,-1.524732));
         AudioSource.PlayClipAtPoint(expSound, Vector3 (1.995417,2.282711,-1.524732));
         Destroy(hit.gameObject);
         var exp = Instantiate(explosion, gameObject.transform.position, Quaternion.identity);
         Destroy(gameObject);    
     }

}

Hey I had same problem, I know it is a long time you post this. I found this post on google, I did not like that you had to give all your turrets vector 3 position. I have lot of them in my game. Here is better way of doing this, you just delay the time after sound and before the explosion.

var explosion : Transform;

var sfxHit: AudioClip;

function OnTriggerEnter ( hit : Collider) {

if(hit.gameObject.tag == "wormProjectile") 
{
    audio.PlayOneShot(sfxHit);
    yield WaitForSeconds (0.4);
    Destroy(hit.gameObject);
    var exp = Instantiate(explosion, gameObject.transform.position, Quaternion.identity);
    Destroy(gameObject);
}

}

For those using c#

To play audio on collision with a destroyed object

     public AudioClip coindAudio;
 
     
     
     
     
     void OnTriggerEnter(Collider cc) 
     {
     
     
 
             if(gameObject.tag == "coin")
             {
                 codeGUI.coin++;
                 AudioSource.PlayClipAtPoint(coindAudio,gameObject.transform.position);
             }
             
         
         }
     }
