Hi, i’m saving data in binary files, is my first time doing this, and i have a problem, when i compile the game, in my computer save and load data correctly, but in other compuers not work. I don’t know whats happen, someone can help me?, thanks so much.

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

[Serializable]
public class SaveData
{
    public bool[] isActive;
    public int[] highScores;
    public int[] stars;
}

public class GameData : MonoBehaviour
{
    public static GameData gameData;
    public SaveData saveData;

    // Start is called before the first frame update
    void Awake()
    {
        if (gameData == null)
        {
            DontDestroyOnLoad(this.gameObject);
            gameData = this;
        }
        else
        {
            Destroy(this.gameObject);
        }
        Load();
    }

    void Start()
    {
        
    }

    public void Save()
    {
        //Create a binary formatter which can binary files
        BinaryFormatter formatter = new BinaryFormatter();

        //Create a route from the program to the file
        FileStream file = File.Open(Application.persistentDataPath + "/GameData.dat", FileMode.Create);

        //Create a copy of my save data
        SaveData data = new SaveData();
        data = saveData;

        //Actually save the data in the file
        formatter.Serialize(file, data);

        //close the data stream
        file.Close();

        Debug.Log("Saved Data");
    }

    public void Load()
    {
        //Check if the save gmae file exists
        if (File.Exists(Application.persistentDataPath + "/GameData.dat"))
        {
            //Create a Binary Formatter
            BinaryFormatter formatter = new BinaryFormatter();
            FileStream file = File.Open(Application.persistentDataPath + "/GameData.dat", FileMode.Open);
            saveData = formatter.Deserialize(file) as SaveData;
            file.Close();
            Debug.Log("Loaded Data");
        }
    }

    void OnApplicationQuit()
    {
        Save();
    }

    void OnDisable()
    {
        Save();
    }
}

That’s why you should never mess with any kind of path strings manually by concatenating string fragments. You should always use System.IO.Path.Combine(). It should work properly on on all systems (linux, mac, android == forward slash, windows == backslash). It also should deal with potential leading or trailing slashes automatically.

So in your case:

string fileName = System.IO.Path.Combine(Application.persistentDataPath, "GameData.dat");
