This is what I needed! Thank you. However can you show or explain how you would save a list? For example, I want to save a list of characters who are in my party and they have stats like hp, mana etc.
Your channel is very helpfull,theres few content on youtube about this part of development and you do a lot of stuff about it,thank you for producing it
I don't get why your film isn't first in search, better knowledge and way more modular. I watch it once and i already have idea how can i implement it after some modification in my game. more "how to" films shows they way to save, made on specific subject, which need to get more info about they sampled project, here i get info how it works and how i can use it without spending time on getting in to creators way of thinking. great job!
I have a problem. When I add ""public SaveObject so;"" on TestObject it gives me an error like it can't be recognized... Some idea? Thanks for the tutorial.
i'm still stuck on this but I'm keeping at it. I feel like your video is much easier to follow than Brackeys as he names all of his variables the same damn thing -__- I am laughing hard at the auto generated closed captions though XD "the freeze will create one more private static poo directory" hahaha
Yeah man, keep practicing! No one gets it first time over Brackeys is 100% a great source. I learned a lot from him myself but there are a few flaws imo And yeah, I've seen a few of the captions it generates for me, TH-cam must really have a hard time with my accent 😂 Keep up the good work my dude, you'll be a pro in no time!
@@comp3interactive Definitely not trying to speak badly of Brackeys, I owe most of my knowledge to him :D I finally got the code working I'm happy to say, i missed the last part where you added in the new directory if there wasnt one. Now its just figuring out how to get the values in my game to save to this script :P
@@flaviokonti5522 It does make a lot of sense though, with the current script. If I use it the way it is. My game would be broken. When you're setting items in a scene based off of this save data. If you return it null you of course get a null reference exception. Ex. My game starts up for the first time and attempts to load, file exist returns false and sets my saveobject to null. Which in turn now breaks every single thing that is set of off this data.
I want to use this system to store the data on the amazon s3 bucket , for all my players game state , but the really problem that is bothering me , what if I want to add new features to my game , how shall the file schema change can be implemented upon the existing binary files , plz someone reply
@@flaviokonti5522 I am using database for stats , but its more kind game , there are going to be lot of data related to grid map ,positioning , buidling levels , troop etc , so i am thinking about saving all this state info in files , am I wrong ?
@@sandeeproy3126 I would avoid using files for anything except basic savedata or scriptable objects and only localy on device, but thats me personally! Try and see how it works, maybe it works great then comeback here and let us know.
Hmm I'm not sure then man. If you remove this script then does it work again? Because this doesn't use anything called Graph so I can only assume it's an error with a package you may have in the project?
You can tweak it to use inheritance 100%. That's the way I often use it myself, this way was a slightly simpler way as an intro to binary Serialization. In this method I just use SaveObject as the literal object and throw all my savable variables in there though
@@comp3interactive Thanks for the resposne :) I wonder if formatting works with arrays and lists too? since I plan to save Savable GameObjects in the scene.
Good news. Lists and Arrays are serializable! Game Object however, arent. You'll neetocrrate a cusm class that holds position, rotation etc and save thag
Some great content on your channel but would have to disagree about Binary format. For one you can not serialize monobehaviours with out creating an extension method or arrays of floats ect. Also binary is no safer than xml or json as long as you know your lives/health/score values these can be simply found in a hex editor with a simple decimal search.
Thanks for your comment. When it comes to serializing MonoBehaviour scripts I wouldn't see a benefit of doing that anyway? A MonoBehaviour relies on being in the game scene to be really viable, if its transform data you're wanting to save then this is where ScriptableObjects come in handy. I'd still argue that binary is more secure than XML as its not in a plain-English format, you can definitely edit it with a hex editor (as I do mention in the video) but that requires knowledge about that which, if we're being honest, not many casual gamers do
This is fine if you work in 2d but if you want to track/respawn or mange anything to do with positions in a 3d world having a float array with 7 options for a quaternion does not seem practical when you can use json/xml with vector2/3/quaternion ect.. then a simple pass with Aes or any encryption will stop anyone from from reading your data. As for scriptable objects if done well your data manger is effectively a scriptable object anyway everything can talk to the data manger and be decoupled from each other. I am not out to cause an argument as i said i like your content i just disagree with bin format. Don't underestimate the youth of today when it comes to cracking stuff either they are clever little sods.

I will happily be implementing this tomorrow thanks to you my friend 🤙
Glad to be helping!
Amazing channel! Subscribed :D
Thanks man! Appreciate it!
Said it before, said it again: excellent tutorial!
Perfect Im gonna suscribe to this channel
this bro helped me a lot, thank you!
Sorry for asking again but, I am interested of 9:50 how to create a new save object right there where we have return null; ?
Thank you for the great & clear video!
So great. Thank you for the learning.
awesome thank you finally a clear tutorial :)!
I have a problem. When I add ""public SaveObject so;"" on TestObject it gives me an error like it can't be recognized... Some idea? Thanks for the tutorial.
How to delete game data in Binary
U saved my life again :D
Thank you so much !
Awesome!
I try the code but I got unauthorized access exception: error
How would you generate a backup just in case the original file get corrupted

What if you private your variable how would you save it if it's multiple data, even arrays
😀 !! You have a Brilhant brain !!!
Binary Formatter got tagged as unsecure, unsafe and untrusted by Microsoft. You should learn XOR encryption or Binary Writer class instead.
It's unsecure for data transfer and shouldn't be used for networking paxkages, using it locally for a game's save file is perfectly fine
Hey I struggle with: if there is no save data to load, instead of return null, how to create a new file?
Thank you in advance :)
If theres no save data to load you just inform user theres no load data and return, why would you want to create save file on Load, makes no sense

I got this strange Error message :

@@comp3interactive Found it ! SaveObject was still a MonoBehaviour i didnt chage that. Thx for Help and Best Tutorial on Earth !
Do I inherit from the save object class to put add other variables i want from another object?

Yeah I know man. No arguments here, everyone has their preferential way of doing things. Not everything will work for every situation in ever case
While this tutorial is among the best I’ve seen, binary serialization is NOT safe for use. Use an alternative like JSON if possible!
