Quick code review ;-) * Use using statements for classes that implement IDisposable (e.g. FileStream, BinaryFormatter etc.). Like previous commenters said. * Use System.IO.Path.Combine to combine paths safely. Paths are constructed differently on different OS. This avoids a lot of potential problems. * Use a helper method to convert from Vector3 to float array or better yet, make own struct that contains 3 variables and convert between these.

[@LukeAps]

Thanks man. Yeah, tutorials like this need review. Combine is a crucial thing to point out for OS compatibility.

Please, for the love of god, when you are working with a FileStream, please use a try-finally block and call "close()" in the finally clause. Otherwise, if your deserialize() fails, the file will remain open, which can lead to some super-weird and hard to debug effects.

[@chkypros]

Actually, since FileStream implements IDisposable, you could use the using statement which would effectively do the same but is cleaner. docs.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/using-statement

[@texturem0nkey]

This is a great tutorial. I found it much more useful to use lists rather than arrays for breaking up the Vector3's, however. When you save out, you can break the V3 into separate floats, and then reassemble them on load. This has been particularly helpful for me in trying to save/load multiple groups of item data in a single file, as opposed to just a single item as would be possible with the former method. Also to note it's relatively easy to go from where he has started, to a system where you can specify save/load filenames, and read out items from a directory. If anyone is interested, I can post the code for all of that.

[@hjc1710]

[@TinJ7]

hahaha good point

[@creationsmaxo]

One important thing that is missing in this tutorial is to actually separate the data (PlayerData in this instance) from its FileStream cached data. In this video, it would be a function like: public PlayerData CopyPlayerData(PlayerData From){ PlayerData To = new PlayerData(); To.level = From.level; To.health = From.health; To.position = new float[3]; To.position = From.position[0]; To.position = From.position[1]; To.position = From.position[2]; return To; } The reason for doing this is to separate the data sent to the game-usable data from the Filestream data. Remember that you cannot generate an hard copy a Serializable class (PlayerData in this case) using = . An hard copy of a Serializable class is a copy cached as its own. It can only be done by using "new". So, when you do something like SerializableClass A = SerializableClass B, you're basically add a link reference from A to B. A becomes dependent of B meaning that if B cease to exist, A becomes Null and if B becomes Read-Only, A cannot be edited anymore. This is unlike something like float A = float B which makes A equal to B. Unity, and pretty much any game engine, are NOT able to generate an hard copy a Serializable Class because it ignores what's to copy. The only way to generate an hard copy (cached) of a Serializable class is to cast it as a new one. As such, SerializableClass A = new SerializableClass(); makes sure that A is an instance of a Serializable class of its own. When doing so, the class is obviously in its Default state, hence it's at that point that you want to copy its individual values (and by copying, I mean making its values equals and not just some soft copies).

[@scriptbrix]

Quick tip: Look up how to use the using() statement in C# when working with unmanaged resources such as files. The good news with using the "using" statement is that the file stream will be guaranteed to be closed if you forget to do so yourself.

[@ArjolP]

Thank you Brackeys. I just finished my freshman year as a Computer-Engineer student. I really love programming and I am making little games (alongside from other projects) in my free time in hopes of improving my abilities. I am not extremely knowledgeable at the moment so your videos are extremely helpful. It is quite interesting to me how what I learned in University about File Handling, albeit in C and not in C#, turned out to be quite useful here. I thought Unity would use a completely different way to handle the game files. It was a nice surprise to see they are not doing that (apart from a couple of different things like _persistentDataPath). It feels really nice to know that what I am learning in University can actually be applied in what I do. I know, it is silly for me to say that, because that's what Universities are for, but sometimes it feels like I am just wasting my time there, being taught things that I will never use in everyday life.

[@alejandroh.ontoria6457]

Hey, did you end up working in Game dev?

[@colbysnodgrass3997]

This is neat and definitely one of the more understandable binary save systems out there so great job on that, loved the video. I do have one question, how would you go about extending this to say an inventory? While brainstorming, I thought you might be able to have a library of items to reference and store say an integer value as an id for each item to access it, however with large games like Skyrim I feel this could become tedious.

[@PenguiLino]

Yeah im four years late to this but for anyone with the same question now So i first defined a simple class with an id and how many you have: public class InventoryItem { public int itemID; public int Amount; } Then i make a dictionary of all the items and their corresponding Id's foreach(Item item in Items) { Items.Add(item.ItemID, item); } Then when im loading the items i can use this foreach (InventoryItem item in data.inventory) { AddItemToInventory(Items[item.itemID], item.Amount); } And in order to save the items i can do the opposite and get Ids from items In the data script I just have a list of InventoryItems: public List inventory; and just update that with the encrypted items.

[@seb4542]

Funny Fact: You can adapt Vector3 and even your own scripts for the formatter to save them to binary, it's a little bit longer, but its really useful when you need to save multiple objects and their positions

[@Black_Raven-]

How i can did it?

[@xipheonj]

In your save chain you have the SaveSystem handling the data, it's simply passed the player. In the load chain you pass the data itself back to the Player class and let that class handle the data object. You need to pick a convention. Either pass the player to the SaveSystem.LoadPlayer function as well and have that class manage the data, or pass the already formatted PlayerData object to the SaveSystem.SavePlayer function instead of the player.

[@SlayPlenty]

Cough cough sykoo

[@h4z4rd1000]

You should use the "using() {}"-statement when working with classes implementing IDisposable. using(FileStream stream = new FileStream(path, FileMode.Open)) { // Do Something with the file } This way the file handle will be closed even if an exception is raised from the code inside the curly brackets. You don't need to call .Close() or .Dispose() yourself. Also writing a binary file might be more secure than a plain text file, but in the end, locally stored progress can always be changed, we can only make it more difficult.

[@DynaZor]

For some reason it doesn't work for me... I put your lines instead of the Filestream line of Brackeys, put the PlayerData line between the brackets, then it says "Invalid initializer member declarator" on PlayerData and "Use of unassigned local var.." on stream..

[@stellarstudio5495]

There is a way to save Unity specific types like vectors, sprites, audio clips, etc. As you know, this can be done with JSON, but not be secure. So instead save the class in JSON format and then convert it into binary data. That let's us save a larger variety of fields and is nearly just as fast. Also perhaps XOR the binary with a secret key since anyone can convert binary back into original data. Or if you want to be really secure, encrypt it with AES. Good tutorial, quick and to the point. 👍

[@kas-lw7xz]

You wanna have security? RSA

[@dennisgonzales9521]

If you're concerned about being reversed engineered then I suggest using encryption to your serialized data before saving, and then using decryption after de-serializing.

[@xfata1err0rx89]

Easy enough to just manipulate the data once it's loaded into the RAM and then let the game save that data to your save file. Best security you're going to get with it is having it saved onto an external server so you can better control the data and how things are processed so their local end is synced with the server instead of the other way around. For many single player games, that's not really necessary unless you have systems that tie into an online system such as leaderboards/achievements.

[@Zethneralith]

It's a bit more manual, and you have to update the methods every time you add data that needs to be saved/loaded, but another method I like to use is a BinaryWriter: using UnityEngine; using System; using System.IO; public static class ClassThatSavesThings { public const string PLAYER_SAVE_PATH = @"C:\The\Path\To\The.file"; // The '@' automatically escapes backslashes. public static void SavePlayer(Player player) { // Using a "using" statement causes the stream to be closed automatically when exiting the using. This is important because nothing is really written to disk until the stream is closed. using (BinaryWriter writer = new BinaryWriter(File.OpenWrite(PLAYER_SAVE_PATH))) { writer.Write(player.level); writer.Write(player.health); writer.Write(player.transform.position.x); writer.Write(player.transform.position.y); writer.Write(player.transform.position.z); } } public static void LoadPlayer(ref Player player) { using (BinaryReader reader = new BinaryReader(File.OpenRead(PLAYER_SAVE_PATH))) { player.level = reader.ReadInt32(); player.health = reader.ReadInt32(); player.transform = new Vector3( reader.ReadSingle(), // "Single" is just another name for "float" in this case. It's technically the other way around, but whatever. reader.ReadSingle(), reader.ReadSingle()); } } } Of course, this is a quick and slightly dirty way to do it, but it gives you tons of control over exactly how the data is formatted in binary. The main thing to watch out for is ensuring you read/write data in the same order, otherwise you'll get wrong values for sure. You can also use a BinaryWriter to write to a MemoryStream instead of a FileStream. This is great when you want to get the binary as an array of bytes (byte[]) which can be used to convert your data into Base64. I wrote this in a plain text editor, so there may be some invalid syntax.

BinaryFormatter is insecure and can't be made secure" This video should either be taken down or have a warning.

So do I

Can you make a tutorial how to input data to google spreadsheet in unity and use the data from the google spreadsheet in unity?

[@MarioManTV]

I would use this tutorial: www.red-gate.com/simple-talk/dotnet/c-programming/calling-restful-apis-unity3d/ And adapt it for use with the Google Sheets API here: developers.google.com/sheets/api/reference/rest/

[@Diamond-yn4nu]

thank you very much for this excellent tutorial , you always provide important functions at the heart of games development, keep going.

[@bombshellgames2321]

This improved my game 10x times! Thank you!

[@badgamedevreacts3855]

14:36, bruh i spent 5 min trying to figure out what was wrong with my code then i played the video for the next 5 seconds and proceeded to facepalm

[@gigabit6226]

HAHAHAH

[@subliminalcastillo2126]

I can't count how many times I've done that. I even gave up for a couple days on a project before because of that. lmfao.

[@friidaperez3239]

didnt understan, what do you mean?

[@not_herobrine3752]

the life of a programmer is laced with painful inconveniences

[@dwaghe2444]

LMAO

[@kylewalker8907]

Hey Brackeys, I know this is an old tutorial, but I got a question: This works just fine until I build and run my project. Everything works fine in the editor but no save information carries over when ran on build... any suggestions?

[@Thomason1005]

i think Application.persistentDataPath returns a different path when buildt, this is so your editor save is separate from your buildt game save.

[@zacharywalker-liang7319]

Have you found the solution for this? I have the same issue.

[@Brian-vs9sd]

You could add an extension method to the vector3 class called ToFloatArray, that returns a float array so you don't have to worry about conversions everywhere

[@ziadmahmoud1999]

best brackeysss missed you so much come back for even vlogs only we want to see you more

[@ashir.javed6]

2:48 Has no one noticed the binary file depicted actually has Hexadecimal values written on it :3 but still jokes aside Great tutorial! thanks man!

[@Beaubacon]

need some help. This wouldnt work when I built to android

[@tommywood5337]

Love the video, super helpful, totally know what to do now, really helpful, thanks! :)

[@Karim-id3ke]

this guide saved probably many days of my life keep it up!

[@LucasWithAC]

how do you do load a save/game if there isn't one to begin with?

[@marioaviles19]

You don't, it will just return null. that was what the else{ return = null} thing was in the LoadPlayer method , I believe. But I'm pretty new to this

[@codyhusky9335]

Great to see a tutorial on this. I'll definitely use this one day. A side note though Brackeys. You should teach better C# practices... 1. Consider using the `var` keyword, this allows more flexible code, faster to write and reads and sounds better than `Stream stream = new Stream()`, so repetitive! 2. Don't be scared to throwing errors, instead of returning null, the caller should be responsible for handling errors and it doesn't know what happened if you just return null. 3. Consider using `using` statements, they encapsulate any disposable object (such as your stream) and dispose it automatically when the scope closes. 4. Use native .net functions such as Path.Combine, dont assume paths don't end with slash or even that the OS uses slashes, this function will handle that all for you. Would love to see you teaching these, just one step closer to nicer code in Unity...

[@g3ck037]

The first tip is not good in my opinion, as i wouldn't want to debug your code if you regularly use 'var' (unless it's for variables that exist only for 2 lines of code).

[@codyhusky9335]

I was doubtful too before I started using it. Turns out it's basically never a hindrance. The IDE will tell you the type if you hover over it and if you don't want to do that the initialization is usually very close by. Not to mention the name usually tells you anyway!

[@Sebastian198910]

That’s not all. From a clean code perspective there is much to improve von brackys. For me it even looks odd that he copies single lines instead of just doubling them with Ctrl + D. As someone who learned and deals with IODA architecture all the time and who only codes the whole day, I find his C# skills average as max and his .NET knowledge as basic. But when it comes to unity he simply overcomes my knowledge by the same amount at least.

[@dannehsg978]

Sebastian Kruse yeah he purposely make them as basic as possible for beginners or intermediates like me because my school just started using unity

[@lipnyCzlowiek]

I am not sure how using var is a better practice. C# is strongly typed language for a reason.

[@cubyte4640]

Great tutorial! this was very important thing for my game. thank you very much

[@ilsignorfesta7716]

thanks man, you helped me so much
