Get Second Command?

I am trying to make a plugin. And to make that I need to know how to get a second command (sub-command). Can someone tell me the easiest way to get the second command. I want to make it like this.

A player types:

Code:

/<command> <second command>

And the <second command> converts into a string. And then I can use the string. I know that I on some way most split the command by space. But I cant get it to work

 

args[1] if you use onCommand().

 

Thanks, but why aint this working then? :

Code:

@Override
    public boolean onCommand(CommandSender sender, Command command, String commandLabel, String[] args) {
        String[] split = args;
        String commandName = command.getName().toLowerCase();
            if (sender instanceof Player) {
                Player player = (Player) sender;

                // If using the command /MyDesc
                if(commandLabel.equalsIgnoreCase("startnew")){
                    System.out.println(args[1]);
                }
            }
            return true;
        }

error code:

Code:

Here is a example code, hope you understand it

Code:

@Override
public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
    if (sender instanceof Player) {
        Player player = (Player)sender;

	if (args.length == 0) {
            System.out.println(args[0]);

            return true;
        } else {
            String subCommand = args[0];

            if (subCommand.equalsIgnoreCase("argumentcommandhere")) {
                // Do something here.

                return true;
            }
        }
    }

    return false;
}

 

because array starts at 0 and to at 1

 

Thanks for your patiens But I cant get it to work. How do i do if I... let say, wants to make a plugin that when you write:

Code:

/iwrote Hej 

A broadcast Message run that broadcasts.

Code:

Playername wrote Hej

How do I do that? I knows how to broadcast and get playername but how do i load "Hej" into a string-variable? Can someone give me an example? Thanks for everything so far

 

That would be:

Code:

@Override public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
    if (sender instanceof Player) {
        Player player = (Player)sender;

        if (args.length == 0) {
            // Main command

             return true;
        } else {
            String subCommand = args[0];

            if (subCommand.equalsIgnoreCase("iwrote")) {
                player.sendMessage(player.getName() + " wrote " + args[1]);
                return true;
            }
        }
    }

    return false;
}

 

The only thing that happens when I type:

Code:

/iwrote hej

Is that it sends information from the plugin.yml, it say like this into the chat:

Code:

/iwrote <subcommand>

How should the plugin.yml file be. I have it like this for the moment:

Code:

name: FirstOne
main: com.bukkit.TryToGuess.NumberOne.NumberOne
version: 1.0
commands:
  iwrote:
    description: Writes out text
    usage: /<command> <subcommand>

What is wrong? :/

 

Do you use a CommandExecutor?

 

Code:

@Override public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
     if (sender instanceof Player) {
         Player player = (Player)sender;
          if (args.length == 0) {
             // Main command
               return true;
         } else {
             String subCommand = args[0]; // subCommand now contains the first argument to the /iwrote command
              if (subCommand.equalsIgnoreCase("iwrote")) { // if subcommand is iwrote (so /iwrote iwrote )
                  player.sendMessage(player.getName() + " wrote " + args[1]); // send the player a message with the second argument in "/iwrote iwrote ____"
                 return true;
             }
         }
     }
      return false; // send the yml stuff to the sender
 }

I commented up the code. Note that if you use the command '/iwrote iwrote' with no args[1] this will cause a NPE.

 

Okey, thanks Now its working. But I dont understand why I have to type:

Code:

/iwrote iwrote hej

instead of:

Code:

/iwrote hej

Thanks anyway. Thanks!

 

That's just how the code is written. You can change the code.
