        getCommand("show").setExecutor(this);
               
               
             
            }
    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args)
      {
        if (cmd.getName().equalsIgnoreCase("hide"))
        {
          if (!(sender instanceof Player))
          {
            sender.sendMessage("Run this command in the game.");
            return true;
          }
          Player player = (Player)sender;
          Location loc = player.getLocation();
          if (args.length == 0)
          {
          player.playSound(loc, Sound.ENDERMAN_TELEPORT, 1, 1);
          player.sendMessage(ChatColor.translateAlternateColorCodes('&', getConfig().getString("HideMessage")));

          }
          if (args.length == 1)

            }
            else
            {
             Player name = target.getPlayer();
             String name1 = name.getName();
              player.sendMessage(ChatColor.translateAlternateColorCodes('&', getConfig().getString(ChatColor.YELLOW + name1 + "OnlyHide")));
              player.playSound(loc, Sound.ENDERMAN_TELEPORT, 1, 1);
              player.hidePlayer(target);
            }
          }
          return true;
        }
        

        if (cmd.getName().equalsIgnoreCase("show"))
        {

          Player player = (Player)sender;
          Location loc = player.getLocation();
          if (args.length == 0)
          {
          player.playSound(loc, Sound.ENDERMAN_TELEPORT, 1, 1);
          player.sendMessage(ChatColor.translateAlternateColorCodes('&', getConfig().getString("ShowMessage")));
          for (Player allplayer : getServer().getOnlinePlayers()) {
            if (!allplayer.isOp()) {
              player.showPlayer(allplayer);
            }
          }
          return true;
          }
          if (args.length == 1)
          {
            Player target = getServer().getPlayer(args[0]);
         
            if (target == null)

              player.sendMessage(ChatColor.translateAlternateColorCodes('&', getConfig().getString(ChatColor.YELLOW + str + "PlayerIsnt")));
            }
            else
            {
                Player name = target.getPlayer();
                 String name1 = name.getName();
              player.sendMessage(ChatColor.translateAlternateColorCodes('&', getConfig().getString(ChatColor.YELLOW + name1 + "OnlyShow")));
              player.playSound(loc, Sound.ENDERMAN_TELEPORT, 1, 1);
              player.showPlayer(target);
            }
          }
          return true;
        }
        return false;
      }
}

 

this is a plugin.yml

Code:

name: HideAndShow
version: 1.0
main: cream.sun.HideAndShow
author: Cream_sun
default-permissions: NOT_OP

commands:
  HideAndShow:
    usage: /hide [show]
    default: true

this is a config.yml

Code:

HideMessage: '&6&lPlayer is hiding.'
ShowMessage: '&a&lPlayer is showing.'
PlayerIsnt: '&6&l isn't.'
OnlyHide: '&6&l is hiding.'
OnlyShow: '&6&l is showing.'

I wrote a this plugin, but don't run thier command. (/hide & /show)
Where am I wrong? Please tell me.

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

Could you tell me more?
Sorry, I'm a biginner.

 

Is this correct?

Code:

commands:
  hide:
    default: true

 

Thank you very much!!
But, it becomes error when I run their commands.

 

Oh, sorry. I forgot to put a photo.

like thier.

 

Sorry, i don't understand that you say.

 

Should I show config.yml?

Code:

HideMessage: '&6&lPlayer is hiding.'

ShowMessage: '&a&lPlayer is showing.'
PlayerIsnt: '&6&l isn't.'
OnlyHide: '&6&l is hiding.'
OnlyShow: '&6&l is showing.'

my config.yml

 

Code:

    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args)
      {
        if (cmd.getName().equalsIgnoreCase("hide"))
        {
          if (!(sender instanceof Player))
          {
            sender.sendMessage("Run this command in the game.");
            return true;
          }
          Player player = (Player)sender;
          Location loc = player.getLocation();
          if (args.length == 0)
          {
          player.playSound(loc, Sound.ENDERMAN_TELEPORT, 1, 1);
          player.sendMessage(ChatColor.translateAlternateColorCodes('&', getConfig().getString("HideMessage")));
          for (Player allplayer : getServer().getOnlinePlayers()) {
            if (!allplayer.isOp()) {
              player.hidePlayer(allplayer);
            }
          }
          return true;

here?

 

I do not know what I should fill in in front of this line.
Could you write an example what value I should put?

 

In other words print the value of the strings when I run </hide>. Right?

 

Well, why will an error be given?
Error contents: An error is given when I run </hide> or </show>.
But,

Code:

player.playSound(loc, Sound.ENDERMAN_TELEPORT, 1, 1);

This code is run.

 

I posted.
Because I did not know where I should do, I copied all it for the time being.

Sorry, Should I post getConfig().getString("HideMessage") to the console?

 

I think I found the error:

Should be:

Code:

player.sendMessage(String.format(ChatColor.translateAlternateColorCodes('&', getConfig().getString("PlayerIsnt")),str));

And in your config:

Code:

PlayerIsnt: '&6&l%s is not hidden.'

You were trying to get the String "§ePlayerName PlayerIsnt" which is null.
You did this not only at this line of code.

 

Thank you everyone.
But, there is a new trouble!
A file isnt made when I reloaded it.
