hey, so when i try and use the code below to destroy my cloned bullet it doesnt destroy, it doesnt even fire the onCollisionEnter event so i am very confused. the bullet has a collider and a rigidbody so i am very confused. any help is appreciated.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class shootScript : MonoBehaviour
{
    public Rigidbody projectile;
    public Transform barrelEnd; 


    // shoot the gun *bang*
    void Update()
    {
        if (Input.GetMouseButtonDown(0)) {
            projectile = Instantiate(projectile, barrelEnd.position, barrelEnd.rotation);
            projectile.velocity = transform.TransformDirection(-30, 0, 0);

            Destroy(projectile.gameObject, 10);

        }

    
    }

    // destroy the bullet on enemy impact
    private void OnCollisionEnter(Collision collision)
    {
        Debug.Log("test");

        if (collision.gameObject.tag == "enemy") {
            Destroy(gameObject);
        }
    }
}

The OnCollisionEnter function will be triggered on the GameObject that actually collides with something.
So your “bullet” gameobject needs a script with said OnCollisionEnter function.
Then this will work as intended.
Currently you basically listen for collisions of the gameobject that this “shootScript” is on.
