Vanish setCanPickUpItems

So I am making a vanish plugin and I put player.setCanPickupItems(false); it does not work

Full code:

Code:

package me.max.commands;

import java.util.ArrayList;
import me.max.MainCore;

import org.bukkit.Bukkit;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.event.Listener;

public class Vanish implements CommandExecutor, Listener{
   
    public Vanish(MainCore mainCore) {
        // TODO Auto-generated constructor stub
    }
    public ArrayList<Player> vanish = new ArrayList<Player>();

    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args) {
    if(!(sender instanceof Player)) {
        sender.sendMessage("You must be a player");
    }
   
    Player player = (Player) sender;
   
    if(commandLabel.equalsIgnoreCase("v") || commandLabel.equalsIgnoreCase("vanish")) {
        if(!vanish.contains(player)) {
            for (Player online : Bukkit.getOnlinePlayers()) {
                online.hidePlayer(player);
               
            }
            vanish.add(player);
       
            player.sendMessage(MainCore.TAG + "You have now vanished");
           
            player.setAllowFlight(true);
            player.setFlying(true);
            player.setCanPickupItems(false);
        } else {
            for (Player online : Bukkit.getOnlinePlayers()) {
                online.showPlayer(player);
               
            }
            vanish.remove(player);
            player.setAllowFlight(false);
            player.setFlying(false);
            player.sendMessage(MainCore.TAG + "You are no longer vanished");
        }
       
    }
    return true;
           
   
    }

    }


   

 

@MaxNatural The setCanPickUpItems method it's inside LivingEntity, it's used to mobs (like Zombies) to know if they can pick up items or not, it does not work for players.

You need to listen for PlayerPickupItemEvent and cancel it or make the player not collide with entities.

 

@Konato_K how would I do that. Sorry i'm a little new

 

Create a "PlayerPickupItemEvent" and cancel it.

 

@MaxNatural Read this

 

just use the PlayerPickupItemEvent and check if the ArrayList "vanish" contains the player
if so, cancel the event
