Setting UUID from Player Name [Command]

Hey guys, I've bee stumped on 1 little part. I've been trying to make a command where you set the player as a premium player. (/setpremium <playername>) But I'm stuck on being able to get the players uuid from the name you type in.

The player has a time limit (as a trial) and when that time is up, the player cant player no more. Unless, you type a command (/setpremium), and that will have them be able to play and do whatever.

I'd like to be able to have this work with buycraft or enjin when donating... There would be a command for it which is /setpremium {Name} but it has to work when the player is also offline. Everything is set into a config.

I'm just stuck at the OfflinePlayer part. Heres my code:

Code:java

if(cmd.getName().equalsIgnoreCase("setpremium")) {
if(args.length == 0) {
MessageManager.getInstance().msg(player, ChatColor.RED + "/setpremium <player>");
return true;
} else if(args.length == 1) {
String playerName = args[0];
 
Methods.setPremium(/*WhatName?*/);//This is the part I need help with
 
MessageManager.getInstance().msg(player, ChatColor.GREEN + "Set player " + ChatColor.RED + playerName + ChatColor.GREEN + " to be Premium!");
}
}

This is my "setPremium" method:

Code:java

public static void setPremium(OfflinePlayer pName) {
Files.users.set(pName.getUniqueId() + ".premium", true);
stopTimer();
Files.saveUsers();
}

All help is appreciated!
If you need any other info, just let me know and I'll provide as much as I can!

 

Epicballzy What do you mean by premium?

Code:java

OfflinePlayer offline = Bukkit.getOfflinePlayer(name)

 

Epicballzy Oh right okay. You'll want to look at the getOfflinePlayer() method - that can take a player's name

When I do:

Code:java

public static void setPremium(OfflinePlayer pName) {
        Files.users.set(pName.getUniqueId() + ".premium", true);
        Files.saveUsers();
    }

Command:

Code:java

String playerName = args[0];
                @SuppressWarnings("deprecation")
                OfflinePlayer oPlayer = Bukkit.getPlayer(playerName);
                Methods.setPremium(oPlayer);

I get a nullpointer on lines 45 and 32.
45: Files.users.set(pName.getUniqueId() + ".premium", true);
32: Methods.setPremium(oPlayer);
I think its because its not finding the players name I'm typing in? I really have no clue

 

When im on my computer im gonna look at it, but at line 32 you must use Bukkit.Getofflineplayer(playerName)

Two things:

1. You're invoking all of this code in a static context. Does it need to be static? Why not create one instance of the class somewhere and invoke the methods in a non-static context through the instance.
2. Either your OfflinePlayer (pName and oPlayer) or users is null.
