How to show score another scene ? And reset the score when the restart scene?

Well, I’m beginner in unity and I am using this script to the score and record . When my character dies he carries the Game Over Scene , and only shows the record , the score is reset. As for the score appears on the scene Game Over? And how do I score zero when the “Play” scene restart ?

using UnityEngine;
using System.Collections;
using UnityEngine.UI;

public class Manager : MonoBehaviour {
	
	public Text		Highscore;
	public Text		Score;
	public int		score = 0;
	
	
	// Use this for initialization
	void Start () {
		Highscore.text = " " + PlayerPrefs.GetInt ("Highscore");
		Score.text = " " + score;
	}
	
	// Update is called once per frame
	void Update () {
		if (score > PlayerPrefs.GetInt ("Highscore")) {
			PlayerPrefs.SetInt("Highscore", score);
		}
		Score.text = " " + score;
	}
}

Not excactly sure what you are looking for.

When you start your gamescene you set score to 0;

void Start()
{
score = 0;
}

When your game is complete you compare score with highscore. As you did already.

//attach your script to empty game object and make it prefab & add it to any scene you want to show your score in

public class Manager : MonoBehaviour {
public static Manager man; //make the class static you can access any where.

void Awake () //add this to your script
	{
		if (man == null) 
		{
			DontDestroyOnLoad(gameObject);
			man = this;
		}
		else if (man != this)
		{
			Destroy(gameObject);
		}
	}
//now in the button wher you reset the scene or in start
Manager.man.score = 0;
