Ecco a voi lo script (scusate per i nomi strani) : using UnityEngine;
using System.Collections;

public class vitapermoneta : MonoBehaviour {
GameObject moneta;
GameObject nemico;

// Use this for initialization
void Start () {
moneta = GameObject.FindWithTag ("moneta");
nemico = GameObject.FindWithTag ("nemico");
}

// Update is called once per frame
void Update () {


}
void OnCollisionEnter2D(Collision2D collisione)
{

if(collisione.gameObject.tag == "Player")

Destroy(nemico);
}


}
