Freeze Command Not Working

Hey guys! I've been workin' on this command, but when I use it, it just returns the command back to me! It just says "/freeze". (This is my return false way of saying you failed lol.) Well this is the code, I have the class and command in the Main class, and the command in the plugin.yml, but alas, it doesn't work. Here's the code!

Code:

package com.infinity.lobby.commands;

import java.util.ArrayList;
import java.util.HashMap;

import com.infinity.lobby.main.Main;

import org.bukkit.ChatColor;
import org.bukkit.block.Block;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerMoveEvent;

public class FreezeCommand implements CommandExecutor, Listener
{
  public final HashMap<Player, ArrayList<Block>> hm = new HashMap<Player, ArrayList<Block>>();
   
  Main plugin;
  public FreezeCommand(Main instance)
 
  {
     
    this.plugin = instance;
   
  }
 
public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args)
  {
    if(!(sender instanceof Player)){
        sender.sendMessage(ChatColor.DARK_RED + "You must be a player to use this command.");
        return true;
    }
    Player p = (Player) sender;
    if(cmd.getName().equalsIgnoreCase("freeze")){
        if(p.hasPermission("lobby.fun")){
            if(args.length == 0){
                if(hm.containsKey(p)){
                    hm.remove(p);
                    p.sendMessage(ChatColor.GOLD + "You unfroze yourself.");
                }else {
                    hm.put((Player) p, null);
                    p.sendMessage(ChatColor.GOLD + "You froze yourself!");
                }
            }else if (args.length == 1){
                if(p.getServer().getPlayer(args[0]) != null) {
                    Player target = p.getServer().getPlayer(args[0]);
                    if(!hm.containsKey(target)){
                        String tname = target.getName();
                        String sname = p.getName();
                        hm.put(target, null);
                        p.sendMessage(ChatColor.GOLD + "You froze " + ChatColor.AQUA + ChatColor.BOLD + tname + ChatColor.RESET + ChatColor.GOLD + ".");
                        target.sendMessage(ChatColor.GOLD + "You were frozen by " + ChatColor.AQUA + ChatColor.BOLD + sname + ChatColor.RESET + ChatColor.GOLD + ".");
                    }else if(hm.containsKey(target)){
                        String tname = target.getName();
                        String sname = p.getName();
                        hm.remove(target);
                        p.sendMessage(ChatColor.GOLD + "You unfroze " + ChatColor.AQUA + ChatColor.BOLD + tname + ChatColor.RESET + ChatColor.GOLD + ".");
                        target.sendMessage(ChatColor.GOLD + "You were unfrozen by " + ChatColor.AQUA + ChatColor.BOLD + sname + ChatColor.RESET + ChatColor.GOLD + ".");
                    }
                }else {
                    sender.sendMessage(ChatColor.DARK_RED + args[0] + " was not found.");
                }
            }
        }else if(!(p.hasPermission("lobby.fun"))){
            p.sendMessage(ChatColor.RED + "You must be rank Minor God or higher to use this command.");
        }
    }
   
    return false; 
  }

@EventHandler
public void onPlayerMove(PlayerMoveEvent e){
    if(hm.containsKey(e.getPlayer())){
        e.getPlayer().teleport(e.getPlayer());
    }
}
 
}

Thanks for the help! Byeeeeeeeeeeeeeeeeeeeeeeee!

 

because you return false; at the end (return false = show usage of command, return true = show nothing)

wouldnt be just a List<Player> better and cancel the PlayerMoveEvent?

Aaaaaaand you can't teleport to a block which doesn't exist (you stored player, null in the hashmap)
