Solved Disallow players to move items in their inventory

I am currently working on my own plugin, and want to make it so that players can't move the items I give them on join in their inventory. Now they can move them all around, which results in them also being able to dump them in GUIs. This is how far I got:

Code (Text):

package me.PartyProNL.PartyParks.Listeners;

import org.bukkit.event.Listener;
import org.bukkit.event.block.BlockBreakEvent;
import org.bukkit.event.block.BlockPlaceEvent;
import org.bukkit.event.inventory.InventoryInteractEvent;
import org.bukkit.event.player.PlayerDropItemEvent;
import org.bukkit.event.EventHandler;

public class Prevention implements Listener {

    @EventHandler
    public void onDrop(PlayerDropItemEvent event) {
        event.setCancelled(true);
    }
    public void onInventoryClick(InventoryInteractEvent event) {
        event.setCancelled(true);
    }
    public void onBlockPlace(BlockPlaceEvent event) {
        if(!(event.getPlayer().hasPermission("partyparks.place"))) {
            event.setCancelled(true);
        }
    }
    public void onBlockBreak(BlockBreakEvent event) {
        if(!(event.getPlayer().hasPermission("partyparks.break"))) {
            event.setCancelled(true);
        }
    }
}

This is the complete code. The anti-drop thing does work, but the one about InventoryInteractEvent does not work. They can still move the items. How can I fix this?

 

Okay, here's what I've got now:

Code (Text):

package me.PartyProNL.PartyParks.Listeners;

import org.bukkit.event.Listener;
import org.bukkit.event.inventory.InventoryClickEvent;
import org.bukkit.event.EventHandler;

public class AntiInventoryMove implements Listener {

    @EventHandler
    public void onInventoryClick(InventoryClickEvent event) {
            event.setCancelled(true);
            event.getWhoClicked().sendMessage("Event recorded!");
    }
}

But I am having other problems, which I think are stopping this from working. I have another file that has PlayerInteractEvent, and I get lots of errors from it saying it couldn't pass the event to my plugin. Here's the code for that file:

Code (Text):

package me.PartyProNL.PartyParks.Listeners;

import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerInteractEvent;

import me.PartyProNL.PartyParks.Menus.PartyParksMenu;
import me.PartyProNL.PartyParks.Menus.ProfileMenu;
import me.PartyProNL.PartyParks.Util.Color;

public class MenuOpener implements Listener{
   
    @EventHandler
    public void onPlayerInteract(PlayerInteractEvent event) {
       
        Player p = event.getPlayer();
        if(event.getPlayer().getInventory().getItemInMainHand().getItemMeta().getDisplayName().equals(Color.color("&e&lPartyParks &8>> &7Right click"))) {
            PartyParksMenu.partyparksMenu(event.getPlayer());
        }
        if(event.getPlayer().getInventory().getItemInMainHand().getItemMeta().getDisplayName().equals(Color.color("&e" + p.getName() + " &8>> &7Right click"))) {
            ProfileMenu.profileMenu(event.getPlayer());
        }
    }
}

Does any of you see anything wrong with this? I can't seem to figure it out, and I think this is what's stopping the other thing from working.

 

Okay, I managed to fix the error in the second file. I got an error due to me checking for a thing that had a possibility of not being there. Now the anti move thing does work!
