[Solved] Command Blocking Problem

In my plugin BattleNight, I am adding a feature to block other plugin commands that are not whitelisted while a player is in the Battle. At the moment it is not working and would like your help.

This is what I have at the moment:

Pasted code (open) Pasted code (close)

PHP:

package me.limebyte.battlenight.core.Listeners;
 
import java.util.List;
 
import me.limebyte.battlenight.core.BattleNight;
 
import org.bukkit.command.Command;
import org.bukkit.event.EventHandler;
import org.bukkit.event.EventPriority;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerCommandPreprocessEvent;
 
public class CommandBlocker implements Listener {
 
    // Get Main Class
    public static BattleNight plugin;
    public CommandBlocker(BattleNight instance) {
        plugin = instance;
    }
    
    @EventHandler(priority = EventPriority.HIGHEST)
    public void onPlayerCommandPreprocess(PlayerCommandPreprocessEvent event) {
        if (event.isCancelled()) return;
        if (!plugin.BattleUsersTeam.containsKey(event.getPlayer())) return;
        if (!plugin.config.getBoolean("Commands.Block")) return;
        
        List<String> whitelist = plugin.config.getStringList("Commands.Whitelist");
        
        String[] cmdArg = event.getMessage().split(" ");
        Command command = plugin.getServer().getPluginCommand(cmdArg[0].trim().replaceFirst("/", ""));
        
        // Don't block BattleNight commands
        if (command.getName().equals("bn")) return;
        
        // Check if the command is listed else cancel
        if (whitelist.contains(command.getName().toLowerCase())) {
            return;
        }
        else {
            // Check if there is any aliases
            if (command.getAliases().isEmpty()) {
                // Block it
                event.setCancelled(true);
                plugin.tellPlayer(event.getPlayer(), "You are not permitted to perform this command while in a Battle.");
                return;
            }
            // Check if an alias is listed else cancel
            for (String alias : command.getAliases()) {
                if (whitelist.contains(alias.toLowerCase())) {
                    return;
                }
                else {
                    // Block it
                    event.setCancelled(true);
                    plugin.tellPlayer(event.getPlayer(), "You are not permitted to perform this command while in a Battle.");
                    return;
                }
            }
        }
    }
    
}

The event is registered, names of Players in the Battle are stored in the key of a HashMap, the whitelist is stored as a Bukkit config StringList.

No errors are logged to the console.

 

Add debugging messages everywhere and see where it stops

 

Lol, yeah just did that and found the issue .

 

Great
