[NEED HELP FAST PLEASE] NullReferenceException

Hi.
I am currently building a multiplayer game and using this asset. First off you guys did an amazing job with realistic fps prefab. Best thing you can buy for an FPS Game and MORE!
I just have one problem.
When i start my multiplayer game up and spawn into the game i keep getting an error everytime i try to pick up objects. Weapons, ammo, Health, etc

The error is:
NullReferenceException
UnityEngine.GameObject.GetComponent[FPSPlayer] () (at C:/BuildAgent/work/d3d49558e4d408f4/artifacts/EditorGenerated/UnityEngineGameObject.cs:28)
HealthPickup.PickUpItem () (at Assets/!Realistic FPS Prefab Files/Scripts/Items/HealthPickup.cs:26)
UnityEngine.Component:SendMessageUpwards(String, SendMessageOptions)
FPSPlayer:FixedUpdate() (at Assets/!Realistic FPS Prefab Files/Scripts/Player/FPSPlayer.cs:512)


Here is the code for the 1 object i want to pick up, Any help would be great. Thank you!

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class HealthPickup : MonoBehaviour {
5.     private GameObject playerObj;
6.     private Transform myTransform;
7.    
8.     public float healthToAdd = 25.0f;
9.     public bool removeOnUse = true;//Does this pickup disappear when used/activated by player?
10.    
11.     public AudioClip pickupSound;//sound to playe when picking up this item
12.     public AudioClip fullSound;//sound to play when health is full
13.    
14.     public Texture2D healthPickupReticle;//the texture used for the pick up crosshair
15.    
16.     void Start () {
17.  
18.         myTransform = transform;//manually set transform for efficiency
19.         //assign this item's playerObj value
20.         playerObj = Camera.main.transform.GetComponent<CameraKick>().playerObj;
21.     }
22.    
23.     void PickUpItem (){
24.     FPSPlayer FPSPlayerComponent = playerObj.GetComponent<FPSPlayer>();
25.    
26.         if (FPSPlayerComponent.hitPoints < FPSPlayerComponent.maximumHitPoints){
27.             //heal player
28.             FPSPlayerComponent.HealPlayer(healthToAdd);
29.            
30.             if(pickupSound){AudioSource.PlayClipAtPoint(pickupSound, myTransform.position, 0.75f);}
31.            
32.             if(removeOnUse){
33.                 //remove this pickup
34.                 Object.Destroy(gameObject);
35.             }
36.            
37.         }else{
38.             //player is already at max health, just play beep sound effect
39.             if(fullSound){AudioSource.PlayClipAtPoint(fullSound, myTransform.position, 0.75f);}      
40.         }
41.     }
42. }

 

Actually I think your problem is with FPSPlayer, can you post that code to?

 

can anyone else help me with this problem?

 

You should check if playerObj and FPSPlayerComponent are != null. I suspect one of the GetComponent<>'s is failing.

 

How can i check if they are null, Should i just put that line of code in the void.start area?

 

Code (csharp):

1.  
2.  
3.  
4. void PickUpItem (){
5. //new
6. if(playerObj){ // if player object exists
7.     FPSPlayer FPSPlayerComponent = playerObj.GetComponent<FPSPlayer>();
8.   }
9.  
10. //more new
11. if(FPSPlayerComponent) // if there is a player component
12. {
13.        if (FPSPlayerComponent.hitPoints < FPSPlayerComponent.maximumHitPoints){
14.            //heal player        
15.            FPSPlayerComponent.HealPlayer(healthToAdd);                    
16.            if(pickupSound){
17.                   AudioSource.PlayClipAtPoint(pickupSound, myTransform.position, 0.75f);
18.            }                      
19.            if(removeOnUse){              
20.                    //remove this pickup              
21.                   Object.Destroy(gameObject);
22.            }  
23.        }else{
24.            //player is already at max health, just play beep sound effect
25.            if(fullSound){AudioSource.PlayClipAtPoint(fullSound, myTransform.position, 0.75f);}    
26.        }
27. }//end new if (no player component then don't try to do anything with one)
28. } // end old function
29.  
30.
