lean cape Aug 2, 2025, 7:19 PM

#

but now when i close the UI triggers that error
and a entry i deleted all ways of unlocking remains unlocked

You save and reload the data from PlayerPrefs so the first question is do you clear this when you want to clear the data?

lean cape Aug 2, 2025, 7:22 PM

#

wat

lean cape Aug 2, 2025, 7:22 PM

#

hardy robin You save and reload the data from PlayerPrefs so the first question is do you cl...

i dont, cuz i thought i didnt need it

#

data should go when i close the game

#

and then reappear when i test it again

#

thats why its used saving-methods, for prevent this

hardy robin Aug 2, 2025, 7:22 PM

#

player prefs is persistent so it wont go away unless YOU change it

lean cape Aug 2, 2025, 7:22 PM

#

player prefs?

hardy robin Aug 2, 2025, 7:23 PM

#

Do you not even know what its doing in ValeriaMemories.SaveUnlocks() ??

lean cape Aug 2, 2025, 7:23 PM

#

the preferences

#

oh right

#

holup lemme

#

ah yeah

#

i thought it was like a more polished way to save it pergame

#

i didnt thought would well, be permanent......

interesting...............

#

anyways
then what i should do?

lean cape Aug 2, 2025, 7:24 PM

#

hardy robin Do you not even know what its doing in ValeriaMemories.SaveUnlocks() ??

how do i access to the playerPrefab data? i suposse it may be a database, and databases are always stored somewhere

hardy robin Aug 2, 2025, 7:25 PM

#

On windows playerprefs gets stored in the registry. But if you dont want this data to be kept between game sessions just remove this code

#

It should be obvious

#

Why did you add this in the first place?

lean cape Aug 2, 2025, 7:26 PM

#

hardy robin On windows playerprefs gets stored in the registry. But if you dont want this da...

i mean, i want it to be keep between game sessions, in fact, i want other values to be kept as well

what conflicts me is, i unlocked it in a test, and now i annoying me for the testing

#

for the UX i want it to be permanent

#

for the DX

#

no

hardy robin Aug 2, 2025, 7:27 PM

#

unity has a menu option to clear player prefs for your project

lean cape Aug 2, 2025, 7:27 PM

#

really?

hardy robin Aug 2, 2025, 7:27 PM

#

so you can use that to "reset your data"

lean cape Aug 2, 2025, 7:27 PM

#

also btw, how do fully the player prefs saving works, i can save, EVERYTHING?

hardy robin Aug 2, 2025, 7:27 PM

#

I forget where it is

lean cape Aug 2, 2025, 7:27 PM

#

i mean cuz also something i been trying to investigate is, how to save

#

is a long game

#

i mean, it will be

hardy robin Aug 2, 2025, 7:28 PM

#

player prefs can hold the major core data types so it would be up to you to save what you need to restore game state later

#

its not recommended however and most people instead use something like json to save + load data.
If you wanted to release the game on steam for example and use cloud save, you would need to stop using player prefs.

lean cape Aug 2, 2025, 7:29 PM

#

ok

#

how json save works?

#

also, if i use json saves i would also have to modify this code right?

hardy robin Aug 2, 2025, 7:30 PM

#

yea you would but perhaps thats too complex for you to do at this moment

lean cape Aug 2, 2025, 7:30 PM

#

ok

lean cape Aug 2, 2025, 7:30 PM

#

hardy robin its not recommended however and most people instead use something like json to s...

and if i want to sell it on itchio?

hardy robin Aug 2, 2025, 7:31 PM

#

er probably fine there I don't think they have cloud saves right?

lean cape Aug 2, 2025, 7:31 PM

#

yeah

hardy robin Aug 2, 2025, 7:31 PM

#

its still not great because its not easy for the general user to back up/move save files if the data is in the registry

#

anyway, can you paste this error you get?

lean cape Aug 2, 2025, 7:32 PM

MissingReferenceException: The object of type 'UnityEngine.RectTransform' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object.

hardy robin Aug 2, 2025, 7:33 PM

#

everything plz including the stack trace

lean cape Aug 2, 2025, 7:33 PM

#

Huh thats not even from your code, did you destroy the scroll rect content object?

lean cape Aug 2, 2025, 7:34 PM

#

the what

hardy robin Aug 2, 2025, 7:35 PM

#

the "Content" object of Scrol rect

#

lean cape Aug 2, 2025, 7:35 PM

#

o h

#

yes it does

#

i dont know why tho

#

i think i coded something wrong

hardy robin Aug 2, 2025, 7:36 PM

#

probably your ClearContent() function

#

but that looks okay actually 🤔

lean cape Aug 2, 2025, 7:37 PM

#

i had the vertical group layout on the viewport instead on the contet

#

do it should be on the content?

#

and well, reference the content as the one with the buttons

#

instead of the viewport

hardy robin Aug 2, 2025, 7:38 PM

#

Yes it should be on the content object

lean cape Aug 2, 2025, 7:38 PM

#

good

hardy robin Aug 2, 2025, 7:38 PM

#

Content is what holds the stuff to move around in the scroll view

lean cape Aug 2, 2025, 7:40 PM

#

how i can move it

#

i mean, looks weird

#

verticall is easy, but the reason is on the right, why?

hardy robin Aug 2, 2025, 7:41 PM

#

Your content object should have the Vertical layout component + Content size fitter (with vertical set to preferred size)
You should spawn the buttons as children of the content object.

lean cape Aug 2, 2025, 7:43 PM

#

i thought it did

hardy robin Aug 2, 2025, 7:44 PM

#

I can't see your objects so Im just saying what It should be

lean cape Aug 2, 2025, 7:44 PM

#

for a weird reason when i put upper-center goes to center...but when i put upper-right goes to left
i mean, i can just put it to upper-center, but this is seems sus

#

hardy robin Aug 2, 2025, 7:47 PM

#

alignment shouldnt matter if using content size fitter (which you are not)
Why do we want this? We want the content to auto size its height to fit the buttons

#

here incase you need a demo of how to lay out correctly @lean cape

📎 ScrollViewDemo.unitypackage

#

done with unity 6
