Not dropping certain items on death

Does anyone know how to prevent certain items from dropping on death?

I.E. Preventing people from dropping a special sword on death...

 

@Daffeh Check the drops, and remove what needs to be removed.

Well, how do you convert an item stack to an item drop?

 

@Daffeh The drops already are itemstacks

 

I'm sorry, I didn't realize that, by the way, I'm trying to also save the items that aren't being dropped and if I do that along with getting rid of the items that I don't want dropped. An error occurs... It's not a NullPointerException, so that means that it's probably not because I'm grabbing the item drop after I delete it...

If you wanna see the class that's handling all this here it is:

Code:

public class SoulboundDetection implements Listener {

    ItemDataStorage ids = new ItemDataStorage();
    Map<UUID, List<ItemStack>> soulbound = new HashMap<UUID, List<ItemStack>>();
    List<ItemStack> soulbounditems = ids.getSoulBoundItems();

    @EventHandler
    public void SoulBoundCheck(PlayerDeathEvent e) {
        Player player = e.getEntity();
        List<ItemStack> inventory = e.getDrops();
        List<ItemStack> soulbounditems = new ArrayList<ItemStack>();
      
        for (ItemStack item : inventory) {
            if (item.hasItemMeta()) {
                if (item.getItemMeta().getLore().contains("Soulbound")) {
                    soulbounditems.add(item);
                }
            }
        }
      
        soulbound.put(player.getUniqueId(), soulbounditems);
    }

    @EventHandler
    public void SoulBoundGive(PlayerRespawnEvent e) {
        Player player = e.getPlayer();
      
        if (soulbound.containsKey(player.getUniqueId())) {
            List<ItemStack> soulboundstuff = soulbound.get(player.getUniqueId());
            for (ItemStack item : soulboundstuff) {
                player.getInventory().addItem(item);
            }
            soulbound.remove(player.getUniqueId());
        }
      
    }
  
    @EventHandler
    public void noDrop(PlayerDropItemEvent e) {
        for (ItemStack item : soulbounditems) {
            if (item.isSimilar(e.getItemDrop().getItemStack())) {
                e.getPlayer().sendMessage(ChatColor.DARK_GRAY + "You just can't seem to let go of something this precious...");
                e.setCancelled(true);
            }
        }
    }
}

EDIT: I intentionally didn't put in the drop removal because it was causing errors (as stated above.)

 

@Daffeh You never clear the soul bound items from the drop. Also if 2 people die the first one to respawn will get all their soul bound stuff and the other persons stuff. Look into maps

 

Couldn't you save the items you want to keep in an array list?

 

@Liam Townsley He is doing that but what if 2 people die, that's 2 peoples stuff in the list then the first to spawn will hey everything

 

EDIT: Well, Hout not killing them make it so when their health is less than 0.01 TP them to their spawn location then removing anything that is not soulbound.

 

@Liam Townsley Or just add to a map, much simpler.

 

@bwfcwalshy I never thought of that.
