Solved Getting a UUID from a username

Since I couldn't find one via Bukkit Java Docs, I was wondering if there is a method that I could use to fetch a player's UUID by using their username as an argument. For example: SomeUUIDClass.getUUID(playerName);

I'd like to stay away from using getPlayer(string) then player.getUniqueID(), since the whole reason I want to get the UUID is to not use a deprecated method.

Thanks in advance.

 

pookeythekid No need to be afraid of getPlayer(string) being deprecated, its only like that to alert plugin devs about the change to the UUID system. In 1.8, Bukkit will remove the deprecation on getPlayer(string).

 

Gamecube762 But with 1.8 comes username changing, doesn't it? Isn't that a big problem with getPlayer(string)?

 

evilmidget38 has a couple of classes that handles these very well;

UUIDFetcher - "...for retrieving the UUID of a player given their userame"

NameFetcher - "...for retrieving the username of a player given their UUID"

Use getPlayer(String s) for session. Use UUID if you want to store persistent data to the player (names are no longer unique).

 

CeramicTitan Cool, thanks.

 

pookeythekid

Code:java

Bukkit.getServer().getPlayer(player.getName()).getUniqueId();

or this if you have the player already.

Code:java

player.getUniqueID();

 

That makes no sense, why would use use getPlayer() and input the player object's getName() String, just use player.getUniqueId().

 

KingFaris11 xD Yeah, quite redundant.

JustinsCool15 I said that I wanted to stay away from using getPlayer(string) because in 1.8 player names will no longer be unique.

 

pookeythekid But the name will be unique while they're on the server. It won't change while they're on your server. Right?

 

JustinsCool15 I don't know, but I'm taking the safe path.

Wait a minute... Wouldn't even getting the UUID of a player's username be worthless with 1.8 name changing? I'd think it's as good as getting an OfflinePlayer by using their username.

Edit: Or will players have to change their name to a username that hasn't already been taken?

That is why I linked you to those two resources. They connect to the Minecraft Servers, where thy interact with the data.

 

pookeythekid A situation where name -> UUID would be useful: Say you have an economy that stores based on UUID, the admin wants to give PlayerA money. Rather then the Admin having to get the player's UUID, you simply fetch it (though, locally storing would be better on Mojang servers)

 

xTigerRebornx Haha, funny you say that. I am making an economy plugin that stores by UUIDs. And yes, I do locally store the UUIDs.

CeramicTitan Ohh I get it. Alright, thanks.

Edit: Wait no, I still have a question: If usernames are no longer unique, that means there can be duplicates (go figure). So if you search "pookeythekid" (that's also my MC username) in the Minecraft servers, you may be presented with two pookeythekids. That would mean you could get the wrong UUID, wouldn't it?

 

You are going to have the same UUID regardless of what you change your name to. Also if a name is taken, you probably wont be allowed to take it.

 

CeramicTitan Ah, so there still won't be duplicates. That makes sense now. So, is getPlayer(username) going to become obsolete because it may lead to plugins treating the same players like newbies?

 

What? If Player A joins the server and he is op. If they change their name and join the server, depending how you go about it, they should still be op when the join the server. I don't really see how it will impact.

 

CeramicTitan Never mind, I'll save confusion and leave it at "there won't be duplicates". That's all I needed to know.

 

i use this way, maybe is what you are looking for

Code:java

 
String playername = "eriosgamer"; //Here you can receive the name from a command with something like args[0]
OfflinePlayer offPlayer= Bukkit.getServer().getOfflinePlayer(playername);
UUID id = offPlayer.getUniqueId();
String uuid = offPlayer.getUniqueId().toString();
 

 

There is still a major use case for Bukkit.getPlayer(String), namely user friendly commands.

 

fireblast709 Mm. Good point.

eriosgamer I suppose that'd work, but then it's exactly what I was trying to find an alternative for. It wouldn't work out best with the context in which I'm using it.
