How to pass data between scenes in Unity

Question

How can I pass score value from one scene to another?

I\'ve tried the following:

Scene one:

void Start () {
    score = 0;

There are various way, but assuming that you have to pass just some basic data, you can create a singelton instance of a GameController and use that class to store the data.

and, of course DontDestroyOnLoad is mandatory!

public class GameControl : MonoBehaviour
{
    //Static reference
public static GameControl control;

//Data to persist
public float health;
public float experience;

void Awake()
{
    //Let the gameobject persist over the scenes
    DontDestroyOnLoad(gameObject);
    //Check if the control instance is null
    if (control == null)
    {
        //This instance becomes the single instance available
        control = this;
    }
    //Otherwise check if the control instance is not this one
    else if (control != this)
    {
        //In case there is a different instance destroy this one.
        Destroy(gameObject);
    }
}
