How to save coins and update them?

Question

Unity

I need to save the coins, but when changing the location or restarting the level, the coins are saved once and are not updated, I don’t know how to fix this, please help. I do everything in Unity. here is the code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System;
using System.IO;
public class money : MonoBehaviour
{ public GameObject Money;
private Save sv = new Save ();
private string path;
public static int score = 0;
private void OnTriggerEnter2D(Collider2D collision)
{ score++;

Destroy(Money);

}

// Start is called before the first frame update
private void Start()
{
path = Path.Combine(Application.dataPath, "Save.json");

if (File.Exists(path)) {

sv = JsonUtility.FromJson(File.ReadAllText(path));

}
}

private void OnApplicationQuit()
{sv.score = score;

File.WriteAllText(path, JsonUtility.ToJson(sv));

}
// Update is called once per frame
void Update()
{

}
[Serializable]
public class Save {

public int score;}
}

Answer 1

Alternatively, you can try writing them in PlayerPrefs. But, according to your description, it is not entirely clear when they should be saved. Between launches of levels or between launches of the application itself?

Answer 2

Rename the method OnApplicationQuittoOnDestroy
