Nick Players does not work :(

Hello there, this is my first thread + I´m from germany so my english isnt the best.
So i am trieng to create a nick plugin which gives a player a nother nick.
here is my current code:

Code:

        Player p = (Player) sender;
        if(cmd.getName().equalsIgnoreCase("nick")){
           
                if (args.length == 1) {
                    String name = args[1];
                    p.setDisplayName(name);
                   
                    }

            return true;
        }

and is does not work
Please help.

 

@timtower first, thank you for your fast reply in which one should i put args[0] ?
it would be nice if you could write the code snippet
because when i write that one whit that [0] in the string it just does not work in minecraft

 

in which one? Sry i coded in C# before that. I am new in Java. It would be very kind of you, if you could write the code snippet. thank you

 

@HexaCoreDesigns
see man, you have "String name = args[1];"
The Array args[] starts at 0, so if the cmd is /cmd arg arg2, the args[1] is on really "arg2", so u need to use args[0] instead of args[1] or check if the args.length is more than 2.

Edit by Timtower: removed thread hijack

 

THANK YOU <3 but how can i change the name in the online players list and the skin? isnt that possible
sry if i am annoying.,..
