Set config value through command

I was wondering if there was a way to set a value in the config through a command. For example, /example <message> would set the config value 'money', so when you go to the config, you see money set to whatever <message> was.

Yes there is a way.

Try to make it and if you get stuck post here :}

This works, thanks. http://wiki.bukkit.org/Introduction_to_the_New_Configuration#Setting_Values

I'm thinking about this before I actually write the code. The config value that the command will be setting in my plugin would contain multiple words, with spaces. How do I get it to think that the multiple words are one argument?

You put them back together.

Code:

// in your command

int startArg = 0; // start from first argument, you can change this tough...

if(args.length <= startArg)
    return false; // less args than required ?

StringBuilder str = new StringBuilder(args[startArg]);

for(int i = startArg + 1; i < args.length; i++)
{
     str.append(' ').append(args[i]);
}

String message = str.toString(); // all arguments from startArg blend together in one string

Code:

if (commandLabel.equalsIgnoreCase("money")){
    if (args.length >=1) {
       String money = args[1];
       int moneyamount = Integer.parseInt(money);
       this.getConfig().set("Money",moneyamount);
       this.saveConfig();
       sender.sendMessage("MoneyAmount has been changed to "    + moneyamount);
       return true;
    }
}

is how i would do it

Your code makes the 2nd argument into an integer an sets it into the config... but:

I now have this:

Code:

if(sender instanceof Player) {
        if(cmd.getName().equalsIgnoreCase("ad")) {
            Player player = (Player) sender;
            int startArg = 0;
            if(args.length <= startArg)
                return false;
            StringBuilder str = new StringBuilder(args[startArg]);
            for(int i = startArg + 1; i < args.length; i++)
            {
                str.append(' ').append(args[i]);
            }
            String message = str.toString();
            if(args.length != 1) {
                player.sendMessage("[" + ChatColor.AQUA + "Newspaper" + ChatColor.RESET + "] " + ChatColor.RED + "Incorrect usage! Type /ad <message>");
            } else if(args.length == 1) {
                this.getConfig().set("path.to.string", message);
            }
        }
    } else {
        sender.sendMessage("[" + ChatColor.AQUA + "Newspaper" + ChatColor.RESET + "] " + ChatColor.RED + "This command can only be executed by players.");
    }

It doesn't work, it returns 'if(args.length != 1)'. Why, though?

You're checking if command doesn't have exacly 1 argument...

You need to move that message before my "return false", that's where it checks if it has at least 1 argument.

Still, if you need all arguments, this might seem simplier:

Code:

if(args.length == 0)
{
    sender.sendMessage("You must type a message.");
    return true;
}

StringBuilder str = new StringBuilder(args[0]);

for(int i = 1; i < args.length; i++)
{
    str.append(' ').append(args[i]);
}

getConfig().set("node", str.toString());

Also, why do you limit that command to players, why can't it also be used from console ?

I can't let it be used from console because of a problem with my vault integration.
EDIT: Thanks, this works, and I'm happy

Ehh... and that's your fix, limiting features ? That's a poor fix.

You should fix your vault integration and allow command to be used from console.

That's what I really want to do, and I'm working on it. Also, does you or anyone else know a way to fix it? I used the code that you showed me, but the string is only set until the server reloads or restarts. After I typed in the command, I looked at the config before reloading the server, and it was still the string that was there before I typed /ad <message>.

this.saveConfig();
