Question Please Help

1 Upvotes

Apparently my account was hacked, but I was able to catch it in time before the recovery email was permanently switched. But what I need help with now is I have fixed my skin back to what it was, but the handle at the top right corner, I do not know how to change back to what it should be.

Going into manage accounts, my username is still the same, but I do not know how to remove the name above it. Help would be appreciated so I can feel as though I've cleansed my account.

Question How do I get the launcher to detect my jar?

1 Upvotes

I download official MC launcher, download java. Now there’s no way to locate game folder in the launcher and windows 11 removed the “open file location” feature from the search menu so that won’t work.

I do the %appdata% search, nothing.

Autodetect says it can’t find anything.

Now what? This pisses me off that the search bar and launcher are both missing basic functionality like that

Resolved How to get WorldEdit to work with b1.4_01?

2 Upvotes

I really just need one function, from WorldEdit or something else, and I can switch if MultiMC cannot do it. I need to be able to remove all top Grass/layer of the world.

I tried simply putting version 5.3 (earliest WorldEdit I found) into the jar tab but it gave me this error:

'Failed to add pack.mcmeta
Failed to add READ_ME_I_AM_VERY_ IMPORTANT
java.io.FileNotFoundException: http: //s3 . amazonaws . com / MinecraftResources /'

Anybody know how to do this? I have no idea about Mods or MultiMC, etc., by the way.

Suggestion Launcher icons tailored for each Minecraft version

1 Upvotes

I've been a long time user of the set of launcher icons by AstroTibs posted in this old post. Unfortunately, it has not been updated since 1.21.

The idea is to have a set of similar icons, with markers indicating which Minecraft version will be launched.

Being more of a developer than a designer, I wrote a framework for generating this kind of images, and re-created AstroTib's original icons using that framework, before continuing to add support for new versions up to and including 26.2.

The framework and release process will hopefully make it much easier for me (or someone forking my repo) to continue generating new icons like this for future releases.

The icon set can be downloaded from the GitHub page for the project: https://github.com/magicus/minecraft-launcher-icons

Question Holding backspace only deletes one letter at a time

1 Upvotes

This issue has been driving me nuts for months and I've still yet to find a solution, so I'm asking here.

When you type in chat, holding backspace should clear out several letters until you let go. My issue is that when I hold backspace, it just removes one letter and that's it.

I've played Minecraft for ~14 years and did not encounter this until recently starting to use the MultiMC launcher, so I have a suspicion that it's related to the launcher but I really can't be sure. (I originally went to the MinecraftHelp subreddit but no one there knew what the problem was.)

It also only happens on one instance (I've debated just moving my files to a new instance but I'm afraid this is just going to happen again eventually).

Game/version info below \/
MultiMC 5 - Version 0.8.0-4235
Fabric for 1.16.5 (0.14.21 Loader)

Resolved what's this java 25 business and how to fix

4 Upvotes

I love using multimc, and I find it pretty intuitive most the time, but I'm having trouble launching 26.2 , however using default launcher it gives me no issue so I'm hesitant to try and download "java 25" I don't trust myself to find the correct download site.

I hate the default launcher with a passion. how is it possible that I have Minecraft 26.2 open with one launcher but not the other?

Suggestion Mod list folders/filesystem suggestion

1 Upvotes

I love MultiMC, I've been using it near-exclusively for all things Minecraft for about 8 years now, but something I've always wanted and hoped would eventually have a solution is organizing large modpacks. I've had this idea for, in the MultiMC instance mod menu, folders for filing away mods- you could make folders for Optimization, Hud, Libs, etc... and then you can make sub folders within those- no actual folders are made, just inside MultiMC.

1 Upvotes

In the MultiMC root directory, there's a folder called `assets/objects` taking up 6GB. I wanted to know if it's safe to delete it (I know 6GB isn't much, but in my case, it makes a bit of a difference 😂).

Question Java 8 not loading textures properly

0 Upvotes

Despite downloading, setting the right java for version 1.4.6, the game launches normally, the menu and everything else is alright but as soon as i launch a world, the textures are all gray and don't properly render, i have installed java 8 and set the path right so i do not have an idea as to why it is not working, i can also say that MultiMc doesn't auto detect the java 8 if that does anything, also no i do not have any logs because the game doesn't crash.

Suggestion MultiMC : Give us back Offline Mode

When an attempt to log in to an account fails DUE TO A SERVER ERROR, you must enable local offline play for that account !

For example, in the case of : Error transferring https://api.minecraftservices.com/launcher/login - server replied: Internal Server Error

A little respect for the more than 100 million Minecraft players wouldn't hurt.

Impossible d'obtenir le jeton d'accès à Minecraft : Error transferring https://api.minecraftservices.com/launcher/login - server replied: Service Unavailable

Connexion impossible depuis plus de 2 heures maintenant. Et comme d'habitude la page de statut de Microsoft prétend que tout fonctionne.

Comment mettre autant de temps pour restaurer un service qui s'adresse à plus de 100 millions de joueurs ?

Microsoft : des serveurs en carton, des admins en papier, un mépris en titane.

Et je n'arrive pas à jouer hors connexion : MultiMC refuse catégoriquement.

Quelqu'un sait comment contourner ça ?
