[Any] [SOLVED] Get UUID


Bektor

Recommended Posts

Hi,

 

I'm currently wondering how to get the UUID of the player, as there are several methods which return a UUID,

like

player.getGameProfile().getId()
player.getPersistentID()
player.getUniqueID()
player.getUUID(player.getGameProfile())
player.getOfflineUUID(username)

 

As there are so many different methods, I am wondering which one I should use to store the owner of a block in the tileentity, so that only this owner can access the block.

I would also like to know the difference between all those methods and how those methods handle stuff like for example offline mod when you don't have a internet connection.

 

Thx in advance.

EntityPlayer.getUUID(GameProfile) returns the UUID of the profile if present, otherwise reroutes to EntityPlayer.getOfflineUUID(String).

EntityPlayer.getOfflineUUID(String) returns a UUID generated from a username provided prefixed with OfflinePlayer.

Entity::getPersistentID and Entity::getUniqueID both return the same in case of EntityPlayer - and that would be the result of EntityPlayer.getUUID(GameProfile).

GameProfile::getId returns the UUID of the profile, or null if it is not present(could not connect to Mojang's servers).

 

So there are really 2 cases:

  1. The player is logged in and in that case return the UUID from Mojang's servers 
  2. The player is not logged in and in that case return a UUID generated based on their name.

So all I have to do is call either Entity::getPersistentID or Entity::getUniqueID?

Also, in case of EntityPlayer, those methods return the same, but what would be the difference if it is no player?

Yes, that would be the best way as you can't get null with that method.

Depends on the entity in question. Default implementation provided by Entity returns the same in both of these methods and the default implementation is the only one used by vanilla as far as I am aware. Entity::getUniqueID is used everywhere by vanilla and Entity::getPersistentID is only used by forge. Both of those methods can be overriden, so I can't tell how different mods use/override them.

    • Hi, you guys are probably all tired of having to deal with the same topic everytimes. I want to play mods, but forge doesn't want me to. And after days of videos and forum, i have no choices to ask before giving up.. The classic Error code 1 ( here's my debug.log : https://paste.ee/p/0WMSP). I tryed everything. The Forge version fit the mod version. I have java jdk 17 and the path to java is set. My mods folder is empty. My Minecraft luncher path has been changed. Java, Minecraft and Forged has been reinstalled 3 times. I tryed with the curseforge luncher. The only thing i didn't do, and I think it might be the problem, is updating my graphic card drivers. For the only reason that my computer is an Ace Magician ( Tiny pc) that don't have a graphic card. But then I went with Fabric. And it works just fine.  Anyway I can't find anything so thank you for your help. Sorry for my english if there's any mistake. Razziel.  
    • I am trying to make my own modpack and at the moment it crashes before I can get to the main menu. I have been trying to google and figure it out myself but would really appreciate some help. I've been using CurseForge to install mod and think I've gotten all the dependencies but I'm not 100% sure. I hope I got the paste.ee thing right Thanks in advance! https://paste.ee/p/NXdSO
