Global project variable

Let me start by saying I know that using static is the default method of using global variables. However, it doesn't work for me.

I've got this (very simple) Class:

public class GameSettings
{
    public static Boss chosenBoss;
}

Which I set from another class, depending on user input, for example:

using UnityEngine;
using System.Collections;

public class ChooseMort : MonoBehaviour
{
    public Boss mort;

    // Use this for initialization
    void Start ()
    {
    }

    // Update is called once per frame
    void Update ()
    {
    }

    void OnMouseOver(){
        if(Input.GetMouseButtonDown(0)){
            GameSettings.chosenBoss = mort;
            Application.LoadLevel("MainGame");
        }
    }
}

I then attempt to access this variable once the main scene starts like so:

// Use this for initialization
void Start ()
{
    boss = GameSettings.chosenBoss;
    PositionBoss ();
    ...
}

However, whenever I get to the boss = GameSettings.chosenBoss - It's always null.

I've also tried Singletons after researching and stumbling on to this post: Singletons

But unfortunately these didn't work for me either. I fear that I'm missing something really simple. Can anyone point out where I'm going wrong?

Thanks.

You are attempting to reference GameSettings as if it were a static class. ie..

boss = GameSettings.chosenBoss;

and

GameSettings.chosenBoss = mort;

First you need to instantiate that class in order to use it, because you're not using a static class, or singleton.. (which confuses me slightly as I'm not certain as to why you will need multiple GameSettings..)

Anyway,,

public class ChooseMort : MonoBehaviour
{
    public Boss mort;
    private GameSettings gameSettings;
    // Use this for initialization
    void Start ()
    {
        gameSettings = new GameSettings();
    }

    // Update is called once per frame
    void Update ()
    {
    }

    void OnMouseOver(){
        if(Input.GetMouseButtonDown(0)){
            gameSettings.chosenBoss = mort;
            Application.LoadLevel("MainGame");
        }
    }
}
