im making a car game were the player car collides with an enemy car and destroys it. in level 1 it’ll have 2 cars that can be destroyed. when there are no enemy cars remaining, which will load a new level.

public var explosionPrefab : GameObject;
var beep : AudioClip;

function OnCollisionEnter(col: Collision){
if (col.gameObject.tag == “Player”){
Instantiate(explosionPrefab,col.gameObject.transform);//trigger explosion
Destroy(col.gameObject);
audio.PlayOneShot(beep);
}
}

This is the error:

(6,20): BCE0023: No appropriate version of ‘UnityEngine.Object.Instantiate’ for the argument list ‘(UnityEngine.Transform, System.Object)’ was found.

I dont know whats wrong because it has never happened before that i got this error, ive had a common add a “;” in this or that line. what is wrong what this script?

public var explosionPrefab : GameObject;
var beep : AudioClip;

    function OnCollisionEnter(col: Collision)
    {
    if (col.gameObject.tag == "Player")
    { 
    Instantiate(explosionPrefab,col.gameObject.transform, transform.rotation);
   //trigger explosion 
   Destroy(col.gameObject); 
   audio.PlayOneShot(beep); 
   }
}
A Instantiate function needs 3 variables. What to instantiate, where it should 
Instantiate and what rotation the instantiated object has. You only gave it 2 variables.
