NullReferenceException error

I am trying to follow a tutorial trying to get bullet holes to work but it says there is an NullReferenceException error on line 49. Here is my code.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5.  
6. public class WeaponHandler : MonoBehaviour
7. {
8.     public Gun[] loadout;
9.     public Transform weaponParent;
10.     public GameObject bulletholePrefab;
11.     public LayerMask canBeShot;
12.  
13.     private GameObject currentWeapon;
14.  
15.     void Start()
16.     {
17.        
18.     }
19.  
20.     void Update()
21.     {
22.         if (Input.GetKeyDown(KeyCode.Alpha1)) Equip(0);
23.  
24.         if (currentWeapon != null)
25.         {
26.             if(Input.GetMouseButtonDown(0))
27.             {
28.             Shoot();
29.             }
30.         }  
31.     }
32.  
33.     void Equip(int p_id)
34.     {
35.         if (currentWeapon != null) Destroy(currentWeapon);
36.  
37.         GameObject t_newWeapon = Instantiate(loadout[p_id].prefab, weaponParent.position, weaponParent.rotation, weaponParent) as GameObject;
38.         t_newWeapon.transform.localPosition = Vector3.zero;
39.         t_newWeapon.transform.localEulerAngles = Vector3.zero;
40.  
41.         currentWeapon = t_newWeapon;
42.     }
43.  
44.     void Shoot()
45.     {
46.         Transform t_spawn = transform.Find("Cameras/JimmyCamera");
47.  
48.         RaycastHit t_hit = new RaycastHit();
49.         if(Physics.Raycast(t_spawn.position, t_spawn.forward, out t_hit, 1000f, canBeShot))
50.         {
51.             GameObject t_newHole = Instantiate(bulletholePrefab, t_hit.point + t_hit.normal * 0.001f, Quaternion.identity) as GameObject;
52.             t_newHole.transform.LookAt(t_hit.point + t_hit.normal);
53.             Destroy(t_newHole, 10f);
54.         }
55.     }
56. }
57.  

Can anyone please help me fix this error

 

Looks like Line 46 isn't finding

JimmyCamera

. You can check this by adding

print(t_spawn);

just after Line 46. Post a screencap of your scene's hierarchy. I'm guessing

JimmyCamera

isn't where this code thinks it is.

(Bit of a leap on my part, but try replacing Line 46 with

t_spawn = GameObject.Find("Cameras/JimmyCamera");

. Might work.)

 

Some notes on how to fix a NullReferenceException error in Unity3D
- also known as: Unassigned Reference Exception
- also known as: Missing Reference Exception

The basic steps outlined above are:
- Identify what is null
- Identify why it is null
- Fix that.

Expect to see this error a LOT. It's easily the most common thing to do when working. Learn how to fix it rapidly. It's easy. See the above link for more tips.

 

I replaced line 46 with your version but it says "t_spawn doesn't exist in current context"

 

Oops. Use this instead:

Transform t_spawn = GameObject.Find("Cameras/JimmyCamera");

 

Thank you but now it says that it can't implicitantly convert type UnityEngine.GameObject to UnityEngine.Transform

 

Yup. My bad again. Use this:

Transform t_spawn = GameObject.Find("Cameras/JimmyCamera").transform;

 

Awesome thank you
