Porting a .net to unity: NullReferenceException: Object reference not set to an instance of an objec

Hi folks,

I have a running .net program, that works on console. Now I want to port it over and I am kinda a newbie in Unity.

Code (CSharp):

1. NullReferenceException: Object reference not set to an instance of an object

Here is the code:

This script is the entry point and is attached to an empty GameObject in the editor:

Code (CSarp):

1.  
2. using UnityEngine;
3. namespace QuickstartClient
4. {
5.    
6.     public class Test : MonoBehaviour
7.     {
8.         // Start is called before the first frame update
9.         void Start()
10.         {
11.             QuickStart.SubscribeQAUpdate();
12.         }
13.         // Update is called once per frame
14.         void Update()
15.         {
16.         }
17.     }
18. }
19.  

and it calls that function in the class QuickStart:

Code (CSharp):

1.  
2. namespace QuickstartClient
3. {
4.      private static LServer ls;
5.      class QuickStart : MonoBehavior
6.      {
7.         public static void SubscribeQAUpdate()
8.         {
9.             Debug.Log("... Starting Subscription!");
10.  
11.             Subscription qa_updates = new Subscription("MERGE");
12.             qa_updates.Fields = new string[7] { "timestamp", "message", };
13.             qa_updates.Items = new string[1] { "QA-Updater" };
14.             qa_updates.addListener(new QA_Listener());
15.  
16.             Debug.Log("... " + qa_updates.Fields[0]);
17.            ls.subscribe(qa_updates); \\------>Error
18.  
19.             Debug.Log("... Starting Subscription done!");
20.             }
21.  

ls.subscribe is from a .dll and the fileds are not empty.

Please, what should I do?
Thanks,Slarti

 

Where does "ls" come from ?

 

Code (CSharp):

1. namespace QuickstartClient
2. {
3.      private static LServer ls;
4.      class QuickStart : MonoBehavior
5.      {
6.         public static void SubscribeQAUpdate()
7. ...
8.  

and this is an external .dll that works.

must have dropped out by editing. I re-edited the post

 

ok then you have to instantiate this somewhere / somehow dont you ?

 

Oh gees ... yes thanks.

ls = new LServer(x, y);

Thanks for helping a nooby
