Solved Config.yml doesn't save ??? :(

Hi there,
I'm using a config.yml file in my Plugin ,which should save the uuid of a Player , but when I open the config it's not written in it.... Could anybody help my with that???

MainClass

Code:java

package me.Nico4898;
 
import java.io.File;
 
 
 
import org.bukkit.configuration.file.FileConfiguration;
import org.bukkit.plugin.Plugin;
import org.bukkit.plugin.java.JavaPlugin;
 
 
public class MainVillagerPvP extends JavaPlugin {
 
File newConfig;
FileConfiguration newConfigz;
 
private static MainVillagerPvP plugin;
public static Plugin getPlugin() {
 
JavaPlugin plugin = MainVillagerPvP.plugin;
 
return plugin;
 
}
 
public void onEnable(){
plugin = this;
new quitev(this);
System.out.println("VillagerDrop aktiv!");
loadConfig();
}
 
 
public void onDisable(){
System.out.println("VillagerDrop inaktiv!");
}
 
 
 
private void loadConfig() {
final FileConfiguration cfg = this.getConfig();
cfg.options().copyDefaults(true);
this.saveConfig();
}
}
 

Adds it to Config

Code:java

 
Player p = Bukkit.getPlayer(event.getEntity().getCustomName().toString());
String uuid = p.getUniqueId().toString();
if(!cfg.getStringList("Logouts").contains(uuid)){
cfg.getStringList("Logouts").add(uuid);
MainVillagerPvP.getPlugin().saveConfig();
MainVillagerPvP.getPlugin().reloadConfig();
}

Removes it from Config

Code:java

if(cfg.getStringList("Logouts").contains(uuid)){
cfg.getStringList("Logouts").remove(uuid);
MainVillagerPvP.getPlugin().saveConfig();
MainVillagerPvP.getPlugin().reloadConfig();
}

config.yml

Code:java

Logouts: 

 

What if the player doesn't have a custom name?...
Your path would be 'null'; there's nothing to save.
I also believe that players cannot have a custom name. They can only have a Display Name.

Also, since you are using Bukkit.getPlayer(), it's best to use OfflinePlayer instead of Player because they might not be online.
Alternatively, use Bukkit.getOfflinePlayer();

 

I'm using this code in an enetity death Event and it gets the customname of the Mob , it it has one.

 

you nowhere change any settings in your config

 

Using getStringList().add doesn't actually change the value in the config. What you need to do is:
1. Get the list with getStringList(path)
2. Change the list (add, remove)
3. Save the list with set(path, list)

 

Still doesn't work...

Code:java

List<String> Logout = cfg.getStringList("Logout");
 
if(!Logout.contains(uuid)){
Logout.add(uuid);
cfg.set("Logout", Logout);
MainVillagerPvP.getPlugin().saveConfig();
MainVillagerPvP.getPlugin().reloadConfig();
}

EDIT: Fixed it now
