Save and Load - FROM FILE in binary format [Tutorial][C#] - Unity tutorial 2019

We drop that Playerprefs stuff, and instead save and load our game from a binary file directly in our folder, whatever you do with that file is now in your hands, will put it on your server? Will you store it in your server's database. Many possibilities, does anyone even read these.

Support us on Patreon, this will unlock many perks, from mention in the videos, project files, experience boost on our website and help with your work!

Want the files? You can find everything on the website!

Our team will help you make your project come to life, drop us a message and let's talk.

Join our community, chat with other developers, share your progress and ask a couple of questions

If anyone gets the IOException: Sharing violation error message - I've listed some possible solutions below:
1. Close any folders you have open containing data.ss
2. Close any programs that have data.ss open
3. Run Unity as admin
4. (This one worked for me) Use the using keyword when declaring your file variables in both Save() and Load()

// example of Save()
using (var file = new FileStream(saveFileName, FileMode.OpenOrCreate, FileAccess.Write))
{

formatter.Serialize(file, State);
file.Close();
}

this is awesome, i would've loved to see a more of encrypted and extremely hard to decrypt/break type of save/load system, you might think that its safe but a lot of people nowadays know how binary works and can manage to edit it after trying a little.

I have a question if I wanted to use this save system, and I have multiple objects with similar data that were saved. How can I only get the information about one for the objects?

Hi bro, can you help me make "save load" to this inventory, i tried many times but without success, i hope you could do it


This is the inventory script

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.EventSystems;
using UnityEngine.UI;

public class Slot : MonoBehaviour, IPointerClickHandler
{
private GameObject inventory;

public enum property { usable, displayable, empty};
public property ItemProperty { get; set; }

private string displayImage;
public string combinationItem { get; private set; }

void Start()
{
inventory = GameObject.Find("Inventory");
}


public void eventData)
{
=
().currentSelectedSlot;
= this.gameObject;
Combine();
if (ItemProperty == Slot.property.displayable) DisplayItem();
}

public void AssignProperty(int orderNumber, string displayImage, string combinationItem)
{
ItemProperty = (property)orderNumber;
this.displayImage = displayImage;
this.combinationItem = combinationItem;
}

public void DisplayItem()
{

=
Items/" + displayImage);
}

void Combine()
{

().combinationItem
== &&
().combinationItem!= "")
{
Debug.Log("combine");
GameObject combinedItem =
("Combined Items/" + combinationItem));



ClearSlot();
}
}

public void ClearSlot()
{
ItemProperty = Slot.property.empty;
displayImage = "";
combinationItem = "";
=
Items/empty_item");
}
}

AND THIS IS THE SLOTS SCRIPT

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.EventSystems;
using UnityEngine.UI;

public class Slot : MonoBehaviour, IPointerClickHandler
{
private GameObject inventory;

public enum property { usable, displayable, empty};
public property ItemProperty { get; set; }

private string displayImage;
public string combinationItem { get; private set; }

void Start()
{
inventory = GameObject.Find("Inventory");
}


public void eventData)
{


().previousSelectedSlot
().currentSelectedSlot;
= this.gameObject;
Combine();
if (ItemProperty == Slot.property.displayable) DisplayItem();
}

public void AssignProperty(int orderNumber, string displayImage, string combinationItem)
{
ItemProperty = (property)orderNumber;
this.displayImage = displayImage;
this.combinationItem = combinationItem;
}

public void DisplayItem()
{

=
Items/" + displayImage);
}

void Combine()
{

().combinationItem
== &&
().combinationItem!= "")
{
Debug.Log("combine");
GameObject combinedItem =
("Combined Items/" + combinationItem));



ClearSlot();
}
}

public void ClearSlot()
{
ItemProperty = Slot.property.empty;
displayImage = "";
combinationItem = "";`enter code here`
=
Items/empty_item");
}
}
