NPE with getting a Double from the Config

Hello, I am working with Configs and what not, and I'm getting the following error:

Code:

Not quite sure why, but here are my classes:

My MEZombieListener Class (The first 30 or so lines, it only mentions up to 26 in the Stack Trace)

Code:

package com.etriacraft.MobEffects.Listeners;
 
import org.bukkit.entity.Entity;
import org.bukkit.entity.Player;
import org.bukkit.entity.Zombie;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.entity.EntityDamageByEntityEvent;
import org.bukkit.potion.PotionEffect;
import org.bukkit.potion.PotionEffectType;
 
import com.etriacraft.MobEffects.Config;
import com.etriacraft.MobEffects.MobEffects;
 
public class MEZombieListener implements Listener {
 
    public MobEffects plugin;
 
    @EventHandler
    public void ZombieBlindness(EntityDamageByEntityEvent event) {
        Entity e = event.getEntity();
        Entity damager = event.getDamager();
        String world = e.getWorld().getName();
        double rand = Math.random();
        boolean dodged = false;
        if (rand <= plugin.getConfig().getDouble("Zombie.Blindness.DodgeChance") / 100) {
            dodged = true;
        } if ( plugin.getConfig().getBoolean("Zombie.Blindness.Enabled", true) && damager instanceof Zombie && e instanceof Player && plugin.getConfig().getStringList("Worlds").contains(world) && !dodged) {
            Player player = (Player) e;
            player.addPotionEffect(new PotionEffect(PotionEffectType.BLINDNESS, plugin.getConfig().getInt("Zombie.Blindness.Time"), plugin.getConfig().getInt("Zombie.Blindness.Power")));
        }
    }

and lastly, my config (This one is quite long, so I'll just show you the part in question again)

Code:

Zombie:
  Blindness:
    Enabled: false
    Power: 0
    Time: 500
    DodgeChance: 10.0

If someone could help me figure out what is wrong here, I would greatly appreciate it.

Thanks in advance

bump.

I'm pretty sure there is an easier way to make configs...
http://wiki.bukkit.org/Configuration_API_Reference

 

Why does nobody search? Plugin is null. You need a constructor to assign a value to it.
I start to have a internal FAQ (just a text file on my desktop) which has a question and a answer for you:
Question: How to use a constructor?

Oh I've since fixed it. I have made the config in a much simpler way, not sure why I didn't before.

Thanks V10lator. I forgot to update the thread to solved.
