Solved Making a playerName.yml for each player upon logging in, error.

I'm currently trying to make a configuration file for each player that logs in, to store things such as their home position, their last seen date, and the sorts.

It's all working as planned, it will make a plugins/GoximoBasic/players/MrCyberMonkey.yml
Except, the error is that it won't load the default configuration options, in this case test.test2.

Code:

package me.goximo.net;
 
import java.io.File;
import java.io.IOException;
import java.util.HashMap;
import java.util.Map;
import java.util.Map.Entry;
import org.bukkit.configuration.file.YamlConfiguration;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerLoginEvent;
import org.bukkit.plugin.java.JavaPlugin;
 
public class PlayerFileHandler implements Listener{
 
public PlayerFileHandler(JavaPlugin plugin) {
}
public File folder = new File("plugins/GoximoBasic/players/");
 
@EventHandler
public void onFirstLogin(PlayerLoginEvent event) {
if(!folder.exists()) {
folder.mkdir();
}
File playerFile = new File(folder, event.getPlayer().getName() + ".yml");
if(!playerFile.exists()) {
try {
playerFile.createNewFile();
} catch (IOException e1) {
e1.printStackTrace();
}
}
 
YamlConfiguration playerYaml = YamlConfiguration.loadConfiguration(playerFile);
 
final Map<String, Object> defParams = new HashMap<String, Object>();
playerYaml.options().copyDefaults(true);
// This is the default configuration
defParams.put("test.test2", "yes");
 
// If config does not include a default parameter, add it
for (final Entry <String, Object> e : defParams.entrySet())
if (!playerYaml.contains(e.getKey()))
playerYaml.set(e.getKey(), e.getValue());
 
//Save the config
this.saveConfig();
}
 
}

Here is the error:

Looks like you cut something out of your code or added something (comments?).

 

Code:

try {
    if(!playerFile.exists()) {
        playerFile.createNewFile();
    }
} catch (IOException e1) {
    e1.printStackTrace();
}

EDIT: looking at it again, i'm not sure what i wanted to achieve with this

 

Thanks for all of the help, but after I noticed I was attempting to save the default config, I realized that I'm a dunce...

 

MrCyberMonkey, you realise you made the first thing with goximo, I searched it and top result

-not about codes
