Question by meme2sin · Apr 15, 2019 at 06:18 PM · referencemelee attack

Why is my melee attack not working?

I went ahead and watched a video on how to do 2D melee attacks and copied most of his code but for me it magically doesn't work. As soon as I attack it gives me this error message: NullReferenceException: Object reference not set to an instance of an object PlayerMelee.Update () (at Assets/Character/Script/PlayerMelee.cs:27)

From this I figured out that the error was where I subtracted health from the enemy and I tried making multiples references but it always failed when I try to change its health. The weirdest thing is that this worked in the video.

Here is my code:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class PlayerMelee : MonoBehaviour
 {
     public float StartTimeBtwAttack;
     private float TimeBtwAttack;
 
     public Transform AttackPosition;
     public Vector2 AttackRange;
     public LayerMask WhatIsEnemy;
 
     public float damage;
 
     // Update is called once per frame
     void Update()
     {
         if (TimeBtwAttack <= 0)
         {
             if (Input.GetKeyDown(KeyCode.M))
             {
                 TimeBtwAttack = StartTimeBtwAttack;
                 Collider2D[] EnemiesToDamage = Physics2D.OverlapBoxAll(AttackPosition.position, AttackRange, WhatIsEnemy);
                 for (int i = 0; i < EnemiesToDamage.Length; i++)
                 {
                     EnemiesToDamage[i].GetComponent<Enemy>().health -= damage;
                 }
             }
         }
         else
         {
             TimeBtwAttack -= Time.deltaTime;
         }
     }

And here is the video: video link
