Solved Getting offlinePlayer UUID

In my plugin, every player has their own yml file to store data of them in.
The file is named <uuid of player>.yml

For one of the commands, I need to be able to access an offlinePlayer's file.

However, when I try and use getUniqueId().toString on an OfflinePlayer, I get a NullPointerException, so I'm guessing you can't get the uuid of offline players like that.

What is the quickest and most efficient way to get the uuid of an offlineplayer?

 

OfflinePlayer#getUniqueId() shouldn't throw an NPE. Show us your code.

 

Code:

OfflinePlayer oTarget = Bukkit.getServer().getPlayer(args[0]);

if (!isInt(args[1])){

    sender.sendMessage(PunishUtil.daysNumber);
    return true;
}

int days = Integer.parseInt(args[1]);

String reason = "";

for (int i = 2; i < args.length; i++){
    reason += args[i] + " ";
}

reason = reason.trim();

File file = new File("plugins//MasCore//Punish//Mutes//" + oTarget.getUniqueId().toString() + ".yml");

NPE given on line 19 of above

That is all the code starting where the player variable is assisgned, ending with the line that gives the error

EDIT: I know I shoudln't hardcode the file location, I am getting round to fix this all in one go later, since I have done it many other times in my project. I am 99% sure this isn't the problem.

 

@ItsMas_ I could've swore that you've had a problem like this before, try replacing all "//" with File.separator on line 19 then test, from what I remember this changed your error.

Remember "plugins//MasCore//Punish//Mutes//" should mean "plugins/null/MasCore/Punish/null/Mutes/null/"

 

Or just the getter for retrieving the plugin data folder and the right Constructor for File. I have never needed to use File.separator.

 

@Xerox262
Changed it to this:

Code:

file = new File(plugin.getDataFolder() + File.separator + "Punish" + file.separator + "Mutes" + file.separator + oTarget.getUniqueId().toString() + ".yml");

Still get an NPE on that line

 

@ItsMas_ Damn, didn't realize sooner, you're using Bukkit.getPlayer(String); rather than Bukkit.getOfflinePlayer(String); that would only get the offline player for people that're actually online

 

Thank you so much!
