    void Update ()
    {
        if(Input.GetButtonDown("Fire1"))
        {
            Rigidbody rocketInstance;
            rocketInstance = Instantiate(rocketPrefab, barrelEnd.position, barrelEnd.rotation) as Rigidbody;
            rocketInstance.AddForce(barrelEnd.forward * 5000);
        }
    }
}
```

## **RocketDestruction**

```csharp
using UnityEngine;
using System.Collections;

public class RocketDestruction : MonoBehaviour
{
    void Start()
