errors while geting INT from other obj script

So iam tryng to acces a script from other obj there is a bunch of threads on this and iw read them all but iam still geting this error so here i go

So there are 2 objects in hierachy enemy and damage counter

enemy has script Enemy '
and damagecounter has damgecounter script

so iam tryng to acces damagecounter script for enemy and this is the way iam tryng

on the enemy obj i add this script

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. publicclass Enemy : MonoBehaviour
5. {
6. public GameObject Dmgcounter;
7. public float damage;
8.  
9. voidStart()
10. {
11. damage = GetComponent<damgecounter>().currentdamge;
12. }
13.  
14. }

and for Dmgcounter i just drag and drop the damage counter obj

and this is the script i add to damgecounter object

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class damgecounter : MonoBehaviour
5. {
6.  
7.     public float currentdamge;
8.     public float damage =10f;
9.  
10.  
11.     void Start ()
12.     {
13.         currentdamge = damage;
14.     }
15.    
16.  
17.     void Update ()
18.     {
19.    
20.     }
21. }
22.  

 

First of all, you should read about naming conventions in C#
Then what's the error you're getting

 

First of all I am not sure why there are spaces missing after "public" and "void"

Second:
damage = GetComponent<damgecounter>().currentdamge;

This would mean that your GameObjects with an "Enemy" component also would require the Damagecounter Component.
If i understand you correctly these are on seperate GameObjects within the Scene. So you need to address the proper Gameobject first

 

NullReferenceException: Object reference not set to an instance of an object
Enemy.Start () (at Assets/Scripts/enemy/Enemy.cs:18)

 

so if i read this corectly i need both of the scripst enemy sciprt and damagecounter scrip on the same object ?

 

Well, unless you do something like:
myEnemyGameObject.GetComponent...

 

yeah it would be great if you could write some example i need to get an int from other objects script in C#

+1 actualy you made my day it was such a headache to get this thing work but that litle scene made my day thank you

 

sorry to bother you again but umm ....well i googled and i find something usefull

Code (CSharp):

1. public float damage ;
2.  
3.         GameObject damagecounterobj = GameObject.Find ("Damagecounterobj");
4.         damgecounter Damgecounterscript = damagecounterobj.GetComponent<damgecounter>();
5.         damage = Damgecounterscript.currentdamge;
6.  

it works like a charm but the problem is it only updates once on start how can i make it update all the time and how can i make the currentdamge to a reference so i can use it other actions count find it in google

 

Firs tyou should store the Damagecounterscript (BTW, still you should look at the naming conventions) in a class-level variable, then you call the damage = Damg... in the update method
