"Null reference"

Hello, I'm trying to learn how to script and encountered a null reference error. I know what it indicates, but I cannot figure out what I'm missing. I made another one that works and used its code as a template, but in doing so I created the error. The script is attached to the object that I'm referencing, which as I understand is the object that is supposed to be referenced. Could anyone please offer suggestions as to things that I could look at or even spot an oversight in the code?

Code (CSharp):

1. using UnityEngine;
2.  
3. public class ShootPowerUp : MonoBehaviour
4. {
5.     public GameObject pickupEffect;
6.     PlayerShooting playerShooting;
7.     public int DamageBoost = 25;
8.  
9.     void OnTriggerEnter(Collider other)
10.     {
11.  
12.         if (other.CompareTag("Player"))
13.         {
14.             ShootPowerPickup(other);
15.         }
16.     }
17.  
18.     void ShootPowerPickup(Collider player)
19.     {
20.         Instantiate(pickupEffect, transform.position, transform.rotation);
21.  
22.         PlayerShooting power = player.GetComponent<PlayerShooting>();
23.         power.damagePerShot = power.damagePerShot + DamageBoost; // [B]Null reference[/B] [B]error for this line[/B]
24.         // Debug.Log("ShootPowerPickup");
25.  
26.         Destroy(gameObject);
27.     }
28. }
29.  

 

What is the exact error message and what line referenced in it?

 

that error is saying that the power variable which is your PlayerShooting script, is null. Something is going wrong on your player.GetComponent<PlayerShooting>(); line. Make sure the player object has the PlayerShooting script on it.

 

Or pickupEffect is unassainged

 

Nope it would only be the player object or the GetComponent call, as you're not referencing the pickupEffect object.

 

Line 20?
