code:

Code:

    @EventHandler
    public void playerDeath(EntityDeathEvent event) {
        if ((event instanceof PlayerDeathEvent)) {
            Player player = (Player) event.getEntity();
            System.out.print("KILLED:" + player.getKiller().getDisplayName());
        }
    }

 

That would happen if the player fell, or was killed by any other means that was not another player.

I've also never used getKiller(), so I don't know its behaviour.

 

Code:

if (player.getKiller() instanceof Player) { }

 

Thank you! This resolved my issues.
