[OfflinePlayer] Can't get real UUID! (Online Mode)

I can't get the real UUID of the OfflinePlayer using:

Code:java

UUID uuid = OfflinePlayer.getUniqueID();

Isn't it supposed to return the real UUID? Currently it returns random ones. The server is in Online Mode. Is this supposed to work, or do I need an external API (Fishbans)?

Off-line players don't have a real UUID...

 

I don't think you understand OfflinePlayer. It refers to a Player, that is currently not online, not a Player in Offline Mode. According to this tutorial, it is possible to get the UUID of an OfflinePlayer.

Have they joined the server before? If not then you can't get their UUID.

 

Yes they have.

 

I have same issue. My plugin broke just for this offlinePlayer code,
example:

Code:java

scores.put(p, o.getScore(Bukkit.getServer().getOfflinePlayer(ChatColor.GREEN + "Hits Left:")));

 

Looks like a bug then.

 

OHQCraft
Did you do "Player offlinePlayer = Bukkit.getOfflinePlayer("name");" and try and get the UUID that way. (Yes I know the "bukkit.getOfflinePlayer()" method is deprecated)

 

Code:java

Bukkit.getServer().getOfflinePlayer(ChatColor.GREEN + "Hits Left:");

That's definitely not going to work, unless the player's name is "Hits Left:". I think what you're looking for is:

Code:java

Bukkit.getOfflinePlayer("PlayerName")

As for deprecation, only the Bukkit.getOfflinePlayer(string) method is deprecated. Bukkit.getOfflinePlayer(UUID) isn't deprecated and is the recommended way of getting offline players in 1.7.9.

 

That is for scoreboard, I need to have "Hits left" to show it on scoreboard. This UUID completely broke it and I have no idea how to use it. Example of if player has perm, then he can see repair cost:

Code:java

if(p.hasPermission("ecorep.repair")){
          repair.put(p, o.getScore(Bukkit.getServer().getOfflinePlayer(ChatColor.GREEN + "Repair cost:")));
          } 

Code worked fine untill I added new development build

 

Yes.

 

Sorry, I use to get a UUID ( From online player ) is the following:

Code:java

String uuid = p.getUniqueId().toString(); // p = Player but what you have there depends on your Event ( Command,JoinEvent,... )

 

JoeyDevs Does OfflinePlayer.getUniqueID() work for you? The confusing thing about the bug is, is that they are both the same functions. Both Player and OfflinePlayer get the .getUniqueId() function as they extend AnimalTamer.

 

I will check tomorrow here it's time to sleep for me. So i will check tomorrow but i don't know because how can the server get a UUID from a player that don't exist in the server. I think that shouldn't work by UUID!

 

What about this?

Code:

UUID uu = java.util.UUID.nameUUIDFromBytes(("OfflinePlayer:" + playerName).getBytes(Charsets.UTF_8));

This prints off my UUID just fine.
'Charsets' is com.google.base

 

I'm talking about getting the UUID from the actual Mojang Servers. OfflinePlayer.getUniqueId() is supposed to work, but doesn't.

Can't OfflinePlayer be for online players aswell?

 

Your player name is still not "repair cost:" so I don't see how it would ever work.

 

I made this code for getting UUID from playername. That will work even when player is online and offline. But if the play haven't played before it might throw a HUUGE error.

Code:

@SuppressWarnings("deprecation")
    public static UUID getID(String name)
    {
        Player player;
        OfflinePlayer oplayer;
        UUID ID;
        if((Bukkit.getPlayer(name)) != null){
            player = Bukkit.getPlayer(name);
            ID = player.getUniqueId();
        }
        else {
            oplayer = Bukkit.getOfflinePlayer(name);
            ID = oplayer.getUniqueId();
        }
        return ID;
    }

 

Yes, but I only want to get the UUID.

I used that method but it returns random UUIDs.

OHQCraft Well. Most safe way of doing this would be to use @evilmidget 's UUIDFetcher, which you can find here.

 

It World for me. It probably doesn't if your local server runs in offline mode. (I made that failure earlier)

 

That's, actually, an older version. Newest, and most efficient, version is here

 

FerusGrim Ah yeah, you're right, still had the link to the old version, thanks for telling me.

 

if I'm right Bukkit.getOfflinePlayer(name) would work though however you may get troubles with UpperCase and LowerCase casing plus if the player has never played before it will do probably a lookup request to the site of mojang which may or not freezes the server.

but ive to admit I'm not updated what in the latest commits is changed so I can be mistated also I'm not 100% sure the latest part is true.

but I know that it could be very hard adding offlineplayers to scoreboards again atleast ive seen increasing messages about that.

 

Yeah, it's just a bug.
