I want to ensure only 1 collision happens

Questions & Answers

So when I shoot my bullets and an enemy it sometimes causes 2, or even 3 collisions to happen before the bullet gets destroyed.
code:

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

public class EnemyHealth : MonoBehaviour {

    public float hp;
	void Start () {
		
	}
	
	// Update is called once per frame
	void Update () {
		
	}
    void OnCollisionEnter(Collision col)
    {
        

        if (col.gameObject.tag == "Bullet")
        {
            Destroy(col.gameObject);
            hp -= 1f;
        }

        if (hp < 0.1f)
        {
            Destroy(gameObject);
        }
    }
}

and also if there is a better way to tell if the enemy is dead it would be useful. Thanks in advance

Maybe the collision script should be on the bullet, so when the bullet collides with the enemy it destroys itself. i think the issue is maybe because the enemy health script is accessing the bullet gameobject which doesn’t happen instantaneously. Its what id try next anyways
