Code:

@EventHandler
public void onEntityDeath(EntityDeathEvent e) {
    if(e.getEntity().getType() == EntityType.PLAYER) return; {
        if(e.getEntity().getKiller().equals(EntityType.PLAYER) || e.getEntity().getKiller() != null) {
            SQLStats.addMobKills(e.getEntity().getKiller().getUniqueId().toString(), 1);
        }
    }
}

 

You have a null pointer error on line 27.

Also, instead of getting Types and comparing, you can use instanceof.

Like so: if(e.getEntity() instanceof Player) ..

 

Thanks, man.

 

@DrBooker No problem
