How to access a variable from another C# script in Unity

Question

I am working on a simple game project, and have a problem. The problem is accessing the variable from one script to another.

For example :-

I have 2 Scenes (Game Scene and Game Over Scene), Game Scene has a Player Game Object , who has a int Variable Score.

using UnityEngine;
using System.Collections;

public class Game_Scene_Script : MonoBehaviour 
{
     private int Score ;

     // Use this for initialization
     void Start () 
     {
          Score = 0 ;
     }

     // Update is called once per frame
     void Update () 
     {
          // Let us assume some one played the game
          // And Now the Score is 207
          Score = 207 ; 
     }
}

Now I want to access that int Variable Score in Game Over Scene which a Game Object.

So how can I access that int Variable from that script?

I searched for, but couldn't find any proper answer I wanted. Even-though some answers are in JavaScript , some are in Unity 4.x etc.

Answer 1

You can't, it's private.

Now, that's not the end of things, as I suspect that wasn't really your question.

Firstly, you need a reference to this script. Which you can get from a reference to the game object this script is attached to. GameObject.Find() works sometimes, I don't recommend it, but none the less, once you have the GameObject reference...

Game_Scene_Script sceneScript = gameObj.GetComponent<Game_Scene_Script>();
int score = sceneScript.GetScore();

Of course, that still means you need to either make the Score public or provide an accessor function, GetScore().

public int GetScore() {
    return Score;
}
