Getting Player by UUID

[wind urchin]

I wanted to create a leaderboard system. Using player UUIDs who may not be on the server at the time. Is there a built in function in fabric or would I need to request off the api.

[merry rock]

it has to exist within minecraft itself, as offline mode is a thing

[wind urchin]

Wym

Do you mean there is no way to store the UUIDs and retrieve the username and info on the player?

[merry rock]

no, player data is stored by uuid, and since those uuids still work in offline mode minecraft has to have something to convert that

hmm

though that might be because the client sends its uuid along with its name when joining

[stiff moon]

Yep. If you want you can check out my mod's source code since I'm storing player UUID to username.

Check out https://github.com/Xexplotion/Offline-Players/blob/1.21.1/src/main/java/net/xexplotion/offline_players/mixin/PlayerManagerMixin.java (particularly the disconnect method) and https://github.com/Xexplotion/Offline-Players/blob/1.21.1/src/main/java/net/xexplotion/offline_players/StateSaverAndLoader.java for saving the data persistently

You can't get player server side

like check for players that way.

On Player Join (Server) -> logs UUID and info

[stiff moon]

What?

[stiff moon]

Assuming the player had joined once you can get their username and if they haven’t you can easily make a lookup method to get it form their uuid with mojang api

[wind urchin]

I was just saying your using a mixin. But couldn't I just have the server get the player UUID, Username and then access that. Since it seems that their is not actually method todo this I'd need to create an api request to mojang?

Cause I also wanna pull their face texture

[stiff moon]

The mixin is basically the same thing as a PlayerJoinEvent, I didn’t understand what you meant sorry. If you just want to fetch their face texture it’s a “simple” request to the mojang api.

I even have some code that does exactly what you are trying to do (I think) that I could find lol

[wind urchin]

Do I need to use a mixin for the join event?

[merry rock]

you could, and then store the uuids in a map of playername & uuid somewhere

[wind urchin]

or is there just an event the server could use? Since this mod really only works with a server its intended for multiplayer use

[merry rock]

this is the simplest I can come up with

[stiff moon]

Did you read any of the code I linked? Mixins aren’t required but since I already mixined into the class I use one but you only need the player join event

[wind urchin]

I did

I may of overlooked I thought I saw a code linked to a mixin lol

[stiff moon]

Also if I correctly understand what you want then do you even need usernames?

[stiff moon]

.

[wind urchin]

I am going to display username, face texture and use uuid as the way to pull their information up

[stiff moon]

Ah

[wind urchin]

Also what reference is type? I check'd yours and didn't see a Type class with any of your imported namespaces.
