Arguments problem with my commands

Hey everybody.

I got some trouble with my commands.
Since last time, I don't exactly know, but today it really started annoying me.
I have this Error message when trying to use a command, but the arguments are not exactly, what is needed:

In the plugin.yml my commands are listed like the following:

Code:

commands:
  thecommand:
    description: mydescription
    usage: /<command> <args[1]> //here i use for every command <command> as the first argument and the seccond or so is named otherwise (not args[1])

Well. I will now post an example of my /kill command...
When i use it with the right arguments, the command works, but when i only type "/kill" i get the Error message i posted above.

Code:

        if (cmd.getName().toLowerCase().equals("kill"))
        {
            Player target = this.getServer().getPlayer(args[0]);
            
            if (p.isOp() == false)
            {
                p.sendMessage("Du musst Admin sein um den Befehl zu nutzen!");
                return true;
            }
            else
            {
                if (checkPlayer(target) == false)
                {
                    p.sendMessage("Der Spieler existiert nicht!");
                    return true;
                }
                else
                {
                    target.setHealth(0);
                    p.sendMessage("Du hast " + target.getName() + " gekillt!");
                    target.sendMessage(p.getName() + " hat dich gekillt!");
                }
            }
            
            return true;
        }

I really hope that you can help me :S

BTW: i'm german, so the /kill command is documented in german.

Do this:

Code:

if (cmd.getName().toLowerCase().equals("kill") && args.length>0)

Now if you use /kill nothing happens

The problem was, even without args[0] you were doing the:

Code:

 Player target = this.getServer().getPlayer(args[0]);

 

Okay thanks
Now: is it possible to show the usage when a command isnt used the right way?

Example:
/kill
-> Usage: /kill <name>

And this without coding it into every single Command but with the plugin.yml

 

You could check if either args[0] equals an empty string ("") or check if the array length of args[] is greater than 0, but you have to see which one works.

 

But its still the same thing. The command will just be skipped but there is no message with the description or something like that...

 

Sure you can, just do an if like this one:

Code:

if (args.length <=0){
return false;
}

 

Okay thanks mate.
Works for almost all my commands.
But i think the remaining errors (same Errormessage) are depending on something else.
