Unity Save System

Slot-based save system for Unity with built-in JSON serialization and encryption.

This system allows you to easily save, load, copy, delete, and manage save slots using strongly typed data classes.

How to use

1. Create a serializable data class

using System;

[Serializable]
public class PlayerData
{
  public int coins;
  public int level;
  public float health;
}

2. Save data

PlayerData data = new()
{
  coins = 150,
  level = 5,
  health = 72.5f
};

SaveSystem.SaveDataInSlot(data, 0);

3. Load data

PlayerData data = SaveSystem.LoadDataFromSlot<PlayerData>(0);

if (data != null)
  Debug.Log($"Coins: {data.coins}");

Basic operations

Check if exists

bool doesExists = SaveSystem.DoesSlotExist(0);

Delete slot

SaveSystem.DeleteSlot(0);

or

SaveSystem.DeleteAllSlots();

Copy slot to

SaveSystem.CopySlot(0, 1);

Retrive all active slots

List<int> slots = SaveSystem.FindAllSavedSlots();

Notes

Save files are stored inside Application.persistentDataPath.

Each file follows this format:

save0.save
save1.save
save2.save
