Save Game via Scriptable Object, possible?

Unity Engine
1

Hello,

Im currently working on an inventory system and would like to save the inventories contents at runtime and load the saved contents on new startup of a Standalone / Android / iOS build.

Question: Can this be achieved via Scriptable Objects? Or do I have to create a custom serialization/deserialization/load configurations system on my own?(hope not)

Additional Info: Im planning to use instaces of scriptableobjects to handle an item’s behaviour. It would be great if overriding those instances would be possible somehow. Otherwise i think a better solution would be to use scriptableobject instances just as item prefabs and load those via ID from custom serialization.

No, I’m not going to use Playprefs :hushed:

Thanks in advance,

Apprentice

Found a quick way for saving on local harddrive.

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

[System.Serializable]
public class SaveGame
{
	[SerializeField]
	public Inventory inventory;
	public static int SaveSlot = 0;
	
	public SaveGame ()
	{
		inventory = new Inventory ();	
	}
	
	public void Save ()
	{
		FileStream myStream; 
		string savep = Application.dataPath + "/SavedGames/SaveGame" + SaveSlot.ToString () + ".saveGame";
		myStream = new FileStream (savep, FileMode.Create); 
		BinaryFormatter binFormatter = new BinaryFormatter (); 
		binFormatter.Serialize (myStream, this); 
		myStream.Close ();
	}
	
	public static SaveGame Load ()
	{
		SaveGame oldObj; 
		BinaryFormatter binFormatter = new BinaryFormatter (); 
		string directory = Application.dataPath + "/SavedGames/";
		string savep = directory + "SaveGame" + SaveSlot.ToString () + ".saveGame";
		if ((directory.Length > 0)  (!Directory.Exists (directory))) {
			Directory.CreateDirectory (directory);
		}
		FileStream fs;
		try {
			fs = new FileStream (savep, FileMode.Open);
			if (fs != null) {
				oldObj = (SaveGame)binFormatter.Deserialize (fs);
				return oldObj;
			}
		} catch (FileNotFoundException e) {
			Debug.Log ("There is no savegame!! " + e.Message);	
		}
		
		return null;
	}



}

To make it work all referenced instances(inside savegame class, e.g. Inventory class) that need to be saved have to use [System.Serializable] above class definition and [SerializeField] on above any field that you want to store?

Edit: Is there maybe a way around the try catch?
