Question by SARWAN · Dec 17, 2013 at 06:15 AM · c#classfunctionsaccessing

Accessing Normal Class from another class which derives from Monobehaviour

Hi,

I Created an Normal .CS Script for getting the instance whenever i called the particular function in following script.

 public class Indexer
 {
     private static Indexer instance = null;
     
     public static Indexer GetInstance()
     {
           if(instance == null)
       {
         instance = new Indexer();    
       }
       return instance;
     }
 }

Trying to call GetInstance() in to the Class which derives Monobehaviour like below:

 private Indexer index;
 public class Model : Monobehaviour
 {
     void Start ()
     {
     index = Indexer.GetInstance ();
     }
 }


I am doing this process when user swithces from one scene to antoher scene.(say, Menu to Game scene).

But, because of this line [index = Indexer.GetInstance ();] it hangs and crahses unity many times.

Can anyone help to solve this issue. . ?

The posted code seems in order. It must be something in the constructor of your Indexer that crashes Unity.

Also, making the Indexer a sole public class in your Normal.cs file could help.

That code has a few errors and would not compile.

1: You can not have global variables in C#, the line "private Indexer index;" needs to be inside the Model class.

2: MonoBehaviour is written with an upper case B.

It should work after that though.

Yeah, you're right. I assumed he already got it to compile and the issues are just typos that were introduced when posting the example here. It's good you're pointing them out, though. I didn't notice them at all at first.
