I don't even know what is wrong...

Code:

package us.lupusbikkit.Freeze;
 
import java.util.ArrayList;
 
import org.bukkit.ChatColor;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;

import org.bukkit.plugin.java.JavaPlugin;
 
public class Freeze extends JavaPlugin implements Listener {
    public void onDisable(){
       
        System.out.println(this + " is now disabled!");
    }
    static ArrayList<Player> frozen = new ArrayList<Player>();
    @Override
        public void onEnable(){
        getServer().getPluginManager().registerEvents(this, this);
    }
    public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
            if (command.getName().equalsIgnoreCase("freeze") && sender.hasPermission("freeze.freeze")) {
                Player target = getServer().getPlayer(args[0]); 
                if (!target.hasPermission("freeze.exempt"))       
                    frozen.add(target);
                    sender.sendMessage(ChatColor.GREEN + target.getName() + " has been frozen.");
                    target.sendMessage(ChatColor.RED + sender.getName() + "has frozen you!");
                    return true;
                }
                   
                    else sender.sendMessage(ChatColor.RED + "Cannot freeze that player!");
                    return false;
    }
                                 
            if (command.getName().equalsIgnoreCase("unfreeze") && sender.hasPermission("freeze.unfreeze")) {
                if (args.length != 0) {
                    Player target = getServer().getPlayer(args[0]);
                    frozen.remove(target);
                    sender.sendMessage(ChatColor.GREEN + target.getName() + " has been unfrozen.");
                    target.sendMessage(ChatColor.GREEN + sender.getName() + " has unfrozen you!");
                    return true;
                }
                return false; // This should send the usage message automatically
            }
            return false;
    }
    @EventHandler
    public void onBlockPlace(BlockPlaceEvent event) {
    Player player = event.getPlayer();
    if (frozen.contains(player)) {
        event.setCancelled(true);
    }
    }
    @EventHandler
    public void onBlockBreak(BlockBreakEvent event) {
        Player player = event.getPlayer();
        if (frozen.contains(player)) {
            event.setCancelled(true);
        }
    }
    @EventHandler
    public void onPlayerMove(PlayerMoveEvent event) {
        Player player = event.getPlayer();
        if (frozen.contains(player)) {
            event.setTo(event.getFrom());
        }
       
    }
}

I am getting numerous errors in the if statement for the unfreeze command. Help?

 

What You put:

Code:JAVA

 
if (!target.hasPermission("freeze.exempt"))       
                    frozen.add(target);
                    sender.sendMessage(ChatColor.GREEN + target.getName() + " has been frozen.");
                    target.sendMessage(ChatColor.RED + sender.getName() + "has frozen you!");
                    return true;
                }
 

Should be:

Code:JAVA

 
if (!target.hasPermission("freeze.exempt"))       
                    frozen.put(target);
                    sender.sendMessage(ChatColor.GREEN + target.getName() + " has been frozen.");
                    target.sendMessage(ChatColor.RED + sender.getName() + "has frozen you!");
                    return true;
                }
 

 

It's an ArrayList, not a Map

 

*should learn to read* XD

 

What are your errors? Can we see them?

 

Code:

if (!target.hasPermission("freeze.exempt"))     
                    frozen.add(target);
                    sender.sendMessage(ChatColor.GREEN + target.getName() + " has been frozen.");
                    target.sendMessage(ChatColor.RED + sender.getName() + "has frozen you!");
                    return true;
                }
                 
                    else sender.sendMessage(ChatColor.RED + "Cannot freeze that player!");
                    return false;

I think you're missing some brackets.
