Not sure if that was the right wording for this question but hopefully you guys understand. I’m trying to save my score value in game so that I can display it on the death screen. Thanks in advance!!

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
 public class Score : MonoBehaviour
{
    int scriptScore = 0;
    public Text score;
    int timeUntil = 5;
    public static int Otherscore;

    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
     if (PlayerDeath.isAlive == true)
        {
            score.text = "Score: " + scriptScore;
            timeUntil--;
        }
     if(timeUntil == 0)
        {
            scriptScore++;
            timeUntil = 5;
        }
        Otherscore = scriptScore;
    }
    
}

That’s the script for the score in game. And below is my attempt at displaying it on the death screen.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using TMPro;

public class HighScore : MonoBehaviour
{
    public TextMeshProUGUI highScore;

    void Start()
    {
        highScore.text = PlayerPrefs.GetInt("HighScore", 0).ToString();
    }

    public void displayScore()
    {
        if(Score.Otherscore > PlayerPrefs.GetInt("HighScore", 0))
        {
            PlayerPrefs.SetInt("HighScore", Score.Otherscore);
            highScore.text = Score.Otherscore.ToString();
        }
    }

}

As I don’t know your game logic, I can only make asumption but I think your HighScore and Score components are not called from the same Scene OtherScore is then set to 0 since a new scene have been loaded and every objects destroyed.

However, for many reasons, using a static is not the good approach. You should instead write the HighScore PlayerPref when the game stops instead of when you display scores.

public class Score : MonoBehaviour
{
    // ...

    private void Update()
    {
        if (PlayerDeath.isAlive == true)
        {
            // ...
        }
        else
        {
            EndGame();
        }
    }

    private void EndGame()
    {
        int currentScore = scriptScore; // Mandatory, I don't like the actual name
        int maxScore = PlayerPrefs.GetInt("HighScore", 0);

        if (currenttScore > maxScore)
        {
            PlayerPrefs.SetInt("HighScore", currentScore);
        }
    }
}

Then, in your HighScore class, you can just write the current score.

public class HighScore : MonoBehaviour
{
    public TextMeshProUGUI highscore;

    public void displayScore()
    {
        highScore.text = PlayerPrefs.GetInt("HighScore", 0);
    }
}
