I've never knew that it was that easy to actually save and load using JSON... Thank you so much for this excellent tutorial! Your KZbin Channel is a blessing for every developer.

[@DanPos]

Glad it was helpful!

[@WakingDragon]

Really high quality tutorial! Got me to my goal in one video :)

[@calebadkins1828]

You absolutely saved my game making, it took me a minute to make this work for my game but it worked. You are a beautiful man. I tried several different options and this is the only one that actually did anything, including just creating a save path!

[@DanPos]

Glad I could help 😃

[@graytreegames6151]

I've really been enjoying your inventory/saveload tutorials. The only issue I've run into is missing using statements, which isn't always clear in the videos what using statements were added. I did manage to figure out those, but as a bit of a new game dev student, it would have been helpful to highlight additions to those. Thanks for creating such a great series of tutorials.

[@DanPos]

Hey thanks for the feedback! That's a good point, my IDE will add them for me as I go usually so sometimes I forget to mention them.

[@therendeath4886]

@@DanPos What IDE do you use? (It's lookin pretty darn awesome)

[@DanPos]

@@therendeath4886 I use Rider :)

[@lxs030]

Your the best, thank you

[@DanPos]

My pleasure!

[@322ss]

Thanks for the video. AFAIK concatenating path part strings should be done using Path Combine, not using plus symbol - IIRC Combine takes care of using proper separator character for each platform.

[@GameBob]

will this work on a bunch of instantiated objects? I've been looking everywhere for a way to save creations the player makes.

[@GameBob]

I wouldn't mind just being pushed in the direction of a tutorial on this that works for what I'm talking about. I've tried so many different methods and the only one I found that resembled what I need unfortunately didn't work because the video was missing context (not yours)

[@DanPos]

Check out my base building tutorial, I cover saving and loading player made bases in that

[@Tobiman12]

also the files of that project aint in your patreon but keep up the good job u r doing importent videos for our community

[@DanPos]

Thanks, they should be up there though! I'll have to look when Im back from vacation

[@charlieelane2047]

I’m following your Inventory System Tutorial and I’ve implemented all the save stuff and it all works (yay!) but how would I add the load button to my Start Menu Scene? So I’m on the start menu scene, I click load and it takes me to my save (which is in a different scene).

[@charlieelane2047]

I'm halfway there with this, I got it all to work but I can't figure out how to load my save scene. I have got my current scene name to save in the save data but can't get it to load!

[@AA-ik7jq]

Hi did you ever figure it out? I think that might be to do with saving between scenes

[@aeozithzene]

Will not allow me to put var dir:string = Application.persistentDataPath + SaveDirectory; . Gives me the errors CS1513, CS1001, CS1002, and CS0818. I'm not sure how you typed it and it auto correct into that line. Won't do it for me, could you explain how you did it, do I need to download something for my VS? Thank you.

[@DanPos]

You've put var dir:string, should it not just be var dir, where's the : come from?

[@watercat1248]

To by honest I'm working is multiplayer game and the only reason I want save system is for the setting and player settings if use json I will able to save those data ? And because this for the settings I will perfer if the load happened automatic wean the player enter the game

[@DanPos]

Yeah that will be fine as long as you don't mind them editing the file. To load just make it load in a gamemanager or something when you start the game

[@watercat1248]

@@DanPos I don't I will by problem because like saying this for the setting and the player settings for example If Saman chenge the default sensetivity or resolution with the own it's his dision not mine I don't think I have problem with that is kind the opiset in because I will have able set up custom resolution if the want to Like Said the only thing I will by able to chenge is the setting and the player settings Not position and not such so the are very limited the stuff that I will able to changed

[@DanPos]

@@watercat1248 youre probably just best using PlayerPrefs for that sort of stuff

[@calebadkins1828]

I hope you will see this comment very soon, at 11:55 you set a temporary string. I am not understanding how this is done. I see you write string and then it immediately disappears when you write var, is there a hotkey you a pressing to do this?

[@calebadkins1828]

Sorry, 11:50

[@DanPos]

With rider you can hit alt+enter but just either use var or string doesn't matter which

[@AnthonyMerlyn]

Hey I Love your Inventory Tutorials! Could you do a Video, or tell me if its already exists... about accessing the toolbar with the keys 1-0? and maybe with that a using function? f.e. healing or equiping ?

[@TapeStixxy]

Hey, I'm thinking about doing the same thing soon, so if I find a way to do it, I'll make sure to share it with you (Although it probably won't be nearly as efficient or as clean as if Dan were to do it! )

Tells me path is denied. HELP

[@DanPos]

At which point does it tell you the path is denied?

[@PeterMilko]

I fixed it by doing using FileStream stream = File.Create(Application.persistentDataPath);

[@LJ_Dev]

@@PeterMilko Same here. UnauthorizedAccessException: Access to the path 'C:\Users\USERNAME\AppData\LocalLow\COMPANY\PROJECT\SaveData\' is denied. I solve this already. In my case, my problem was that I was missing the [SerializeFIeld] in the SaveData class properties. But it was NOT a folder permission or access stuff... That drove me crazy.-

How to save scriptable objects?

[@DanPos]

You can't save changes to Scriptable Objects by default, you would need to make a save data struct for the information you want saved and then save / load that into the scriptable object when appropriate
