Solved Saving player name to config help plz and get prize

When someone kills the boss enderdragon. He earns a certain amount of money.
And his name is saved to the config.
But it is not working ;-;

Code:

Prize: 10000
Winner:

My config

Code:java

 @EventHandler
  public void onEntityDeathEvent(EntityDeathEvent event)
  {
  if (event.getEntity().getKiller() instanceof Player)
  {
  Player player = (Player) event.getEntity().getKiller();
  EntityType type = event.getEntityType();
 
  // Example for checking damaged mob
  if (type == EntityType.ENDER_DRAGON)
  {
  Bukkit.broadcastMessage(ChatColor.DARK_PURPLE + "§l "+ player.getName() + ChatColor.GOLD + " §lKilled enderdragon and won the fearless tag!");
  Bukkit.getServer().dispatchCommand(Bukkit.getServer().getConsoleSender(), "newtag clear " + getConfig().getString(player.getName(), "Winner."));
  Bukkit.getServer().dispatchCommand(Bukkit.getServer().getConsoleSender(), "newtag set &c&lFearless " + player.getName());
  EconomyResponse r = econ.withdrawPlayer(player.getName(), getConfig().getInt("Prize."));
  getConfig().set(player.getName(), "Winner.");
  }
  }
  }
 
}

Code.

 

To check if the entity is something:

Code:java

 
if(type instanceof EnderDragon)
 

The give money is deposit, now withdraw.
Also, it's better if you use vault economy so the plugin works with every big economy plugin.
You will have to set the PLAYER to the string. In this case you set the path "playername" to "Winner."

Code:java

 
Use getConfig().set("Winner", player.getName());
