Cannot access a array in another script

Questions & Answers
1

I have 2 scripts and iam trying to acces the array thats made in script 1 but it gives me a nullreferenceexception when i press the start button (which calls Startgame()). Strangely when i use the debug.log in the first script it gives me the corrrect value 100 when i start the game. Game.current.Progress also doesnt have this problem it just works as i expected it to but this is not a array. Is this a bug? Kinda confused now. Do i have to reference a array in a different way than a normal variable?

Script 1:

    using UnityEngine;
        using System.Collections;
        
        [System.Serializable]
        public class Game { 
        	
        	public static Game current = new Game ();
        	public int Progress;
        	public float[] Scores;
        
        		
        	public Game () {
        		Progress = new int();
        		Scores = new float[2];
        		Scores[0] = 100;
        		Debug.Log (Scores [0]);
        	}
        	
        }

Script 2 :

    using UnityEngine;
    using UnityEngine.UI;
    using System.Collections;
    
    public class Menucontroller : MonoBehaviour {
    
    
    
    	void Start (){
    
    		SaveLoad.Load ();
    		foreach (Game g in SaveLoad.savedGames) {
    			Game.current = g;
    		}
    		if (Game.current.Progress == 0) {
    			Game.current.Progress = 1;
    
    		}
    	}
    
    	public void StartGame () {
    		Application.LoadLevel (2);
    		Debug.Log ((Game.current.Scores)[0]);
    
    


       	}

You need to actually gain a reference to the class instance. You can’t simply use a static class qualifier. You can “get” a reference through the other class like this if there is only one instance in the scene:

Debug.Log(FindObjectOfType<Game>().Scores[0]);

However, it’d be better to cache the reference, and use a field.

Even better, you should use the singleton design pattern.

I solved it by making a public static variable that i use as a “interface” between my objects. Since i know there will be only 1 instance of this this seemed a quite simple solution to me:

public static ItemDatabase Interface;

Awake() {
Interface = this;
}

Then i could do somescript.Interface to gain a reference to a script.

I will look in your suggestion though as i have also read there are disadvantages about static variables.
