Crash when mod is exported

[lofty swift]

also im wondering how i can completly redo the main menu

[upbeat sparrow]

When does the error happen?

It's telling you that this.client is null in some screen class btw

[lofty swift]

on launch

[upbeat sparrow]

Do you perhaps have another mod loaded?

[lofty swift]

nope just fabric api that is required

[upbeat sparrow]

Also you'ld probably get more help if you actually linked the sources of your mod

How's anyone supposed to guess what the issue is from that brief error message. What about the game log/ crash report etc.

[lofty swift]

how

[upbeat sparrow]

Is your mod on GitHub?

By the way, are you making a cheat client?

[lofty swift]

no

[lofty swift]

im making a client

@upbeat sparrow u there?

[upbeat sparrow]

Yea but you didn't respond to most of what I wrote

[lofty swift]

I didnt use any other mods than my mod and fabric api
the version is 1.21
my mod is not open source for github
the crash happens on launch
i dont know what is the issue so i just put some general info so if someone decides to help me they can ask for more info

[upbeat sparrow]

What about the crash report or logs?

[upbeat sparrow]

Ah, well. In that case it's probably one of your mixins at fault

[lofty swift]

that is strange because i exported it before with the same mixins and it worked :/

all i changed since that is the path to my accesswidener that i forgot to put in

also this

[upbeat sparrow]

Well, it's certainly a weird issue, but idk what causes it. Look at the main menu or loaging screen mixin it you have one. Maybe it's an issue with initialization order

[lofty swift]

could that happen if i forgot to list a mixin in the mixins of mod.json

[upbeat sparrow]

I guess it could but that's unlikely

[lofty swift]

ye i did forget to list one but it wasnt that

[mortal portal]

Based on the class/function names, you are using an instance of the Screen class before the MinecraftClient is ready. Since you wish to provide nothing more, this is as far as I will help you too.

[lofty swift]

how could i change that?

sorry im late i was watching the olympics opening

[mortal portal]

Unless you provide code, there is no way to tell, except just use a debugger 🤷‍♂️
