    Hi :)
    I gat this PlayerDeathEvent and i get this error when it's not a player that is the killer.

    Here is the code i use:
    Code:
        @EventHandler
        public void playerdeath(PlayerDeathEvent e) {
            Player pk = e.getEntity().getKiller();
            Entity ek = e.getEntity();
            Player pd = e.getEntity().getPlayer();
            e.getDrops().clear();
            e.setDroppedExp(0);
            String killername = pk.getDisplayName();
           
            if (!(ek instanceof Player)) {
                Bukkit.broadcastMessage("bims");
                return;
            }
           
            int lvl = cf.getData().getInt("Lvl." + pd.getName() + ".lvl");
            pd.setLevel(lvl);
           
            pk.giveExp(+17);
            pk.setHealth(20D);
            pd.sendMessage(ChatColor.RED + killername + " dræbte dig!");
        }

    And here is the error:
    I used the command: /kill for this

    a) Wrong section
    b) You are using spigot....
    c) The error occurs here:
    Where is line 38?

    But the reason (I*m just guessing) is: pk can be null, but you are calling
    Code:java
    1. pk.getDisplayName();

    Check if pk is null :)

    Check if pk is null. It is when the player is not killed by another player. Do check the Cause of the event and see if it was player-inflicted damage.
