Changing invalid command message

I'm trying to change the invalid command message, so for example if they typed /releport instead of /teleport it sends the message "TMod - Invalid command"; nothing happens when I do an invalid command, here is the code;

Code:java

package Commands;
 
import java.text.MessageFormat.Field;
 
import org.bukkit.Server;
import org.bukkit.command.SimpleCommandMap;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerCommandPreprocessEvent;
import org.bukkit.plugin.SimplePluginManager;
 
import Core.Core;
import Core.F;
 
public class Unknown implements Listener
{
 
    public void UnknownCommand() throws NoSuchFieldException, SecurityException, IllegalArgumentException, IllegalAccessException
    {
        getCommandMap(Core.plugin.getServer());
    }
 
    public SimpleCommandMap getCommandMap(Server server) throws NoSuchFieldException, SecurityException, IllegalArgumentException, IllegalAccessException
    {
        if(server.getPluginManager() instanceof SimplePluginManager)
        {
            java.lang.reflect.Field f = SimplePluginManager.class.getDeclaredField("commandMap");
            f.setAccessible(true);
            return (SimpleCommandMap) f.get(server.getPluginManager());
        }
        return null;
    }
 
    public static boolean commandExists(String name)
    {
        return Core.getPlugin().getCommand(name) != null;
    }
 
    @EventHandler
    public void onPlayerCommand(PlayerCommandPreprocessEvent event)
    {
          Player player = event.getPlayer();
            String cmd = event.getMessage();
            if(cmd.charAt(0) == '/') cmd = cmd.replaceFirst("/", "");
            cmd = cmd.split(" ")[0];
            if(commandExists(cmd))
            {
                event.setCancelled(true);
                player.sendMessage(F.M("TMod", "Invalid command"));
            }
    }
 
}
 

 

couldnt you just make a boolean and just make it when they type the command releport or any others, send them that message?

 

MooshViolet I'm pretty sure he means to change the message sent when you use a command not listed in the plugin.yml. In which case, is fairly difficult to do.

I've fiund a tutorial on how to override default bukkit commands: http://forums.bukkit.org/threads/tutorial-how-to-override-default-command.165052/

 

wrong
if(cmd.isRegisterd() == false){//meh}

Why in the world would you compare a boolean to false in an if-statement...?

 

MajorSkillage

Code:java

boolean absurd = true == false;
 
//What are you going to do now? Make another boolean?
if(absurd == false)
{
    //Laughs. Just do: if(absurd)
}
 
 

 

Technically it would be;

Code:java

if(!absurd){
}

since you're only running the if statement when it's false >

 

well you got what i ment lol oh and also what if you compared boolean to null ;p null is false to

 

MajorSkillage If you compare a boolean to null, that's when you get compilation errors.
