here is my player script… like i said when i start the game and click on the enemy i want to attack i get a null ref on line 23 of game manager which is line 23 is player.mytarget = hit.transform, and when i click outside of the enemy anywhere in the game i get another null ref on game manager line 27 which is line 27 is player.mytarget = null; im going to post some scripts and hopefully someone can point me in the right direction. if you need more info please let me know… ive been coding for like 2 months.

if (hit.collider != null)
{
player.MyTarget = hit.transform;
}
else
{
player.MyTarget = null;
}
}
}
}
here is my spell script:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Spell : MonoBehaviour
{
private Rigidbody2D myRB;
[SerializeField]
private float speed;
public int damage;
public GameObject damageNumber;
private HealthSystem healthSystem;
public GameObject damageBurst;
public Transform hitPoint;
private Transform target;
// Start is called before the first frame update
void Start()
{
myRB = GetComponent<Rigidbody2D>();
target = GameObject.FindGameObjectWithTag("Target").transform;
}
// Update is called once per frame
void OnTriggerEnter2D(Collider2D other)
{
if (other.transform == target)
{
Destroy(gameObject);
Instantiate(damageBurst, target.position, target.rotation);
var clone = (GameObject)Instantiate(damageNumber, other.transform.position, Quaternion.Euler(Vector3.zero));//creating obj for use in game,
clone.GetComponent<floatingNumbers>().damageNumber = damage;
}
}
}
like i said im very new to coding so if someone could please help me out that would be awesome!
