WebGL Build Error

[hot flume]

here

[late viper]

try the Windows export build , see if everything goes ok

[hot flume]

will let you know

[lime atlas]

i found this forum entry with a simular error
https://forum.unity.com/threads/error-building-webgl-in-2021-2-5f1-ebug_webgl_wasm-build-js-undefined-symbol.1214319/

[late viper]

oh wait that might be it

Notice the JS capitalization

[hot flume]

here ill check that out

[late viper]

hmm although one is SystemFile and one is FileSystem

a bit odd

[hot flume]

its just function names i reference in different scripts

its just me mixing the wording up but they all reference their own stuff

[late viper]

wait so those are ur functions?

[hot flume]

yeah

[late viper]

whats it supposed to do

[hot flume]

So each script that contains that JS_FileSystem_Sync();

Has this up at the top of the script:

        [DllImport("__Internal")]
        private static extern void Js_FileSystem_Sync();
    #endif```

and the wording is just slightly different

bassically my player prefs save between sessions but when I push an update all playerprefs get wiped. According to thsi thread: https://itch.io/t/995985/saving-data-between-webgl-sessions-and-builds

adding this will fix the issue

i believe its force pushing data to the indexedDB

[late viper]

you should not use playerprefs at all f

esp webgl

[hot flume]

yeah ive just never used anything else

[late viper]

its better application.persitentdatapath and use a file

[lime atlas]

in webgl?

[hot flume]

im just new to this sort of stuff so i wouldnt know whatss best

[late viper]

I've read something about itch.io once that mentioned this, forgot where it was

https://itch.io/t/140214/persistent-data-in-updatable-webgl-games

[hot flume]

so i just built to windows and it worked

[lime atlas]

you are correct , found a post on the forum form unity staff that thaid
"Saving to persistent data (to persistentDataPath) is implemented via IndexedDB and should work fine."

[late viper]

Idk much about itch.io so I never tried it myself

[lime atlas]

they call the sync function via this

Application.ExternalEval("_JS_FileSystem_Sync();");

[late viper]

ahh

[hot flume]

in the thread i linked?

[lime atlas]

nope in the post i liked

[hot flume]

well cause my thing uses that same wording?

am i implementing it wrong im just so confused

[lucid kestrel]

I would not trust those JS methods pre-existing and would just add my own jslib method to do this

There is bunch of code online for it

[hot flume]

do you have a link to a tutorial? just kinda ocnfused on how to do that

[hot flume]

any updates to what you guys think I should do?

[hot flume]

wait how do I view exactly which script these errors are coming from?

[late viper]

the errors are coming from ur DLL import

if WebGL #

[hot flume]

the like actual importing of the thing?
