How to access variables from another scene

Unity Courses Ask
#1

I’ve used a different scene for the game over screen in the quiz section. How do i access the score from the previous scene?
Is it even worth it to use a different scene for game over?

You can’t ‘just access’ scores from the previous scene. Those no longer exist. But there are some options;

  • Keep a ScoreManager type object where the score is stored. Put this object in DontDestroyOnLoad. It will persist across scenes
public vlass ScoreManager : MonoBehaviour
{
    private int _score = 0;

    private void Awake()
    {
        // how many objects do we have?
        int count = FindObjectsOfType<ScoreManager>().Length;
        if (count == 1)
        {
            // only one, put it in the DDoL
            DontDestroyOnLoad(gameObject);
        }
        else
        {
            // too many. destroy this one
            Destroy(gameObject);
        }
    }

    public void SetScore(int score)
    {
        _score = score;
    }
    public int GetScore()
    {
        return _score;
    }
}

Now you can set and get the score using FindObjectOfType<ScoreManager>().

  • Save the score to PlayerPrefs and then just read it again on the next scene
// Save the score
PlayerPrefs.SetInt("Score", _score);

// Read the score
int _score = PlayerPrefs.GetInt("Score", 0); // 0 is returned if no score was saved

These are a few that should help

What is playerprefs?

#4

It’s a built in mechanism for storing player preferences. Small things like score
