Multiple Command Arguments

Hello,
How can I make a command allow multiple arguments for it, for example:
/mr chicken pop
What method can I use to make this possible?
Thanks,

Happy crafting,

If your plugin was to listen for the command "/hello" and
would not check for any arguments, if you typed "/hello there" it would
do the same thing as before.

That is because, if you want to have arguments in your command, you don't have to declare them.

In your onCommand method, there is a String[] array passed, usually called something like args.
It is located in the fourth spot:

Code:

public boolean onCommand(CommandSender sender, Command cmd, String label, [B]String[] args[/B]) {
    return false; // -> your code
}

Now that args array contains all the arguments you as a player have passed.
For example, if you were to type "/hello there stranger", args[0] = "there" and args[1] = "stranger".

I hope I was able to help you.

Just to give you a basic example of how one would add the arguments to the command, I will use your example

Code:java

public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
    if (sender instanceof Player) {
        player = (Player) sender;
    }
    if (cmd.getName().equalsIgnoreCase("hello")) {
        if (args.length == 2) {
            if (args[0].equalsIgnoreCase("there")) {
                if (args[1].equalsIgnoreCase("stranger")) {
                    //Do something, perhaps send them a message?
                    player.sendMessage("Hello to you too!");
                    return true;
                }
            }
        }
    }
    return false;
}

 

wow! This is really helpfull thank you guys!!

 

Thanks helped me too !

 

I understand this, but how do i have a string then an int?
Example:
/heal <Player> [amount]

 

Code:java

 
public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        if (sender instanceof Player) {
            Player p = (Player) sender;
            if (cmd.getName().equalsIgnoreCase("heal")) {
                if (args.length == 2) {
                    Player target = Bukkit.getServer().getPlayer(args[0]);
                    if (target == null) {
                        p.sendMessage("That player isn't online");
                    } else {
                        if (isInt(args[1]) == true){
                            target.setHealth(20);
                            target.sendMessage("You have been healed");
                            p.sendMessage("You have healed " + target.getName());
                        } else {
                            p.sendMessage("That is not a valid health value");
                        }
                    }
                }
            }
        } else {
            sender.sendMessage("You must be a player");
        }
        return false;
    }
 
    public boolean isInt(String s) {
        try {
            Integer.parseInt(s);
            return true;
        } catch (NumberFormatException e) {
            return false;
        }
    }
 

I like to use this integer parser boolean for more than one thing.

 

Thanks for that! I will be updating one of my plugins soon because of this!

 

One change, if you want it to set the health of the amount instead of

Code:java

target.setHealth(20);

use

Code:java

target.setHealth(args[2]);

 

Ditto!

 

You need to parse the int/double/float whatever. It's still a string, and to my knowledge, setHealth only takes a double.

Code:java

target.setHealth(Double.parseDouble(args[2]));

 

Yeah, wrote this a while ago, you are correct.

 

lol i watched ur utube videos and now i see u commenting on thread XD
