I am making a game and I want it so that if the user clicks on New Game it will clear the save file and they can start out from the beginning. How would I do that? I’ll add my save scripts for reference.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class GameInfo : MonoBehaviour
{

public int Lives = 3;
public int Score = 0;

void Start()
{
    LoadPlayer();
}

public void AddPoints()
{
    Score += 10;
}

public void LoseLive()
{
    Lives -= 1;
}

public void SavePlayer()
{
    SaveSystem.SavePlayer(this);
}

public void LoadPlayer()
{
    GameStatus data = SaveSystem.LoadPlayer();

    Lives = data.Lives;
    Score = data.Score;
}

}

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

[System.Serializable]
public class GameStatus
{
public int Lives;
public int Score;

public GameStatus(GameInfo player)
{
    Lives = player.Lives;
    Score = player.Score;
}

}

using UnityEngine;
using System.IO;
using System.Runtime.Serialization.Formatters.Binary;

public static class SaveSystem
{

public static void SavePlayer(GameInfo player)
{
    BinaryFormatter formatter = new BinaryFormatter();
    string path = Application.persistentDataPath + "/game.data";
    FileStream stream = new FileStream(path, FileMode.Create);

    GameStatus data = new GameStatus(player);

    formatter.Serialize(stream, data);
    stream.Close();
}

public static GameStatus LoadPlayer()
{
    string path = Application.persistentDataPath + "/game.data";

    if (File.Exists(path))
    {
        BinaryFormatter formatter = new BinaryFormatter();
        FileStream stream = new FileStream(path, FileMode.Open);

        GameStatus data = formatter.Deserialize(stream) as GameStatus;
        stream.Close();

        return data;
    }
    else
    {
        Debug.LogError("Save file not found in " + path);
        return null;
    }
}

}

  1. Make your SavePlayer method take a GameStatus as argument instead of a GameInfo
  2. Add a default constructor in your GameStatus class initializing Lives & Score to 0
  3. Change SaveSystem.SavePlayer(this); to SaveSystem.SavePlayer(new GameStatus(this));
  4. Call SaveSystem.SavePlayer(new GameStatus()); when the New Game button is clicked
