stepping on pressure plate

i'm trying to make a plugin where you step on a pressure plate (which is on top of a redstone block), and it traps you. I started out making it so when you do /freeze it traps you, and that worked. Then I tried to put in the pressure plate part and it doesn't work. Heres my code:

Code:

package me.reece.Bukkit;

import java.util.logging.Logger;

import org.bukkit.Location;
import org.bukkit.Material;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.block.Action;
import org.bukkit.event.player.PlayerInteractEvent;
import org.bukkit.plugin.PluginManager;
import org.bukkit.plugin.java.JavaPlugin;

public class Bukkit extends JavaPlugin implements Listener{
    public static Bukkit plugin;
    public final Logger logger = Logger.getLogger("Minecraft");
    public boolean freeze = false;
    public final BukkitListener bl = new BukkitListener(this);
   
    @Override
    public void onDisable(){
        this.logger.info("Disabled!");
    }
   
    @Override
    public void onEnable(){
        this.logger.info("Enabled!");
        PluginManager pm = this.getServer().getPluginManager();
        pm.registerEvents(bl, this);
        getConfig().options().copyDefaults(true);
        saveConfig();
    }
   
   
    @EventHandler
    public void onPlayerInteract(PlayerInteractEvent event) {
        if (event.getAction().equals(Action.PHYSICAL)) {
            if (event.getClickedBlock().getType().equals(Material.STONE_PLATE)) {
                Location location = event.getClickedBlock().getLocation();
                location.setY(location.getY()-1);
                if(location.getBlock().getType().equals(Material.REDSTONE_BLOCK)){
                    Player player = event.getPlayer();
                    player.sendMessage("You are on a stone pressure plate on a redstone block.");
                if(!freeze){
                freeze = true;
                }
                else{
                    freeze = false;
                }
            }
        }
    }
   
   
    }
   

}

Code:

package me.reece.Bukkit;

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

public class BukkitListener implements Listener{
   
    public static Bukkit plugin;
   
    public BukkitListener(Bukkit instance){
        plugin = instance;
    }

    @EventHandler
    public void onPlayerMove(PlayerMoveEvent event){
        if(plugin.freeze){
            Player player = event.getPlayer();
            player.teleport(player);
        }
    }
   
}

 

@rhunter Stop abusing static
Stop making fields public
You didn't register your listener (the main class one)

 

I'm not sure what you mean. Where am I supposed to do that?

 

In the onEnable.

You need to register all the classes that implement Listener.
