Solved Remove drops

Hey, i'm currently working on a plugin, and one part of it i can't seem to figure out . When you throw a snowball and it hits the ground it explodes, giving poison to any player standing within a radius of 10 blocks for 10 seconds.
The part that is causing difficulties is that i would like to remove the item drops caused to drop by the explosion.

Any ideas?

My Code:

Code:

public class BombListener implements Listener {

    @EventHandler
    public void onProjectileHit(ProjectileHitEvent e) {

        Projectile po = e.getEntity();
        if ( !(po instanceof Snowball) ) return;

        Snowball so = (Snowball) po;

        so.getWorld().createExplosion(so.getLocation(), 2.0F);

        for (Entity en : so.getNearbyEntities(10, 10, 10)) {

            if (en instanceof Player) {

                Player p = (Player) en;

                p.addPotionEffect(new PotionEffect(PotionEffectType.POISON, 120, 1));

                // TODO: Add item drop remove
            }
        }
    }
}

Perhaps try setting the explosion yield to 0, and damage the players manually. Or listen for EntityExplodeEvent, and clear the block list.

 

Do you want the explosion to create a griefing explosion? There is actually a method that creates an explosion with damage that doesn't grief. createExplosion(x, y, z, power, false, false); Otherwise, you can grab the blocks and it's drops and in a delayed task; grab all nearby entities and see if they are items and see if the items are similar enough as the block drops before the explosion.

 

@Agentleader1 , @Assist thanks for the tips. I actually combined the suggestions.
I grabbed the entities in the range of the explosion and than placed them in a list( List<Entity> ), checked if they where items, and removed them.

New code:

Code:

package me.markototh.kit;

import org.bukkit.entity.*;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.entity.ProjectileHitEvent;
import org.bukkit.potion.PotionEffect;
import org.bukkit.potion.PotionEffectType;

import java.util.List;

public class BombListener implements Listener {

    @EventHandler
    public void onProjectileHit(ProjectileHitEvent e) {

        Projectile po = e.getEntity();
        if ( !(po instanceof Snowball) ) return;

        Snowball so = (Snowball) po;

        so.getWorld().createExplosion(so.getLocation(), 2.0F);

        for (Entity en : so.getNearbyEntities(10, 10, 10)) {

            if (en instanceof Player) {

                Player p = (Player) en;

                p.addPotionEffect(new PotionEffect(PotionEffectType.HARM, 3, 2));

                p.addPotionEffect(new PotionEffect(PotionEffectType.POISON, 120, 1));

                // clear entities

                List<Entity> entList = en.getNearbyEntities(10, 10, 10);

                for(Entity current : entList) {

                    if (current instanceof Item) {

                        current.remove();
                    }
                }
            }
        }
    }
}
