My Command:

Code:

        {

 

            if(args.length == 0){
                p.setHealth(0);

            }
            if(args.length == 1){
                Player player2 = getServer().getPlayer(args[0]);

                player2.setHealth(0);
 
                player2.sendMessage("You have been killed by " + p.getName() + ".");
            }      

Please help me, thanks(sorry for my bad english, i am from germany)

 

Is this in onCommand? If so, it needs to return a value (true on success, false on failure)

Furthermore, you should check for the existence of the player specified as the argument before attempting to set their health:

Code:

if (args.length == 1) {
  Player player2 = (getServer().getPlayer(args[0]) instanceof Player) ? getServer().getPlayer(args[0]) : null;
  if (player2 == null) { player.sendMessage("invalid arguments"); return false; }
  // execute your kill code here
}

 

Thanks. But when i type "/tot" the error occurred. "/tot <name>" works fine! I want to whom I enter /tot, that I will be killed

//EDIT: And yes, it is in onCommand.
//EDIT2: onCommand:

Code:

  public boolean onCommand(CommandSender sender, Command cmd, String cmdLabel, String[] args) {
  
        Player p = (Player) sender;

        if (cmd.getName().equalsIgnoreCase("tot"))
        {
 
            if (args.length == 1) {
                  Player player2 = (getServer().getPlayer(args[0]) instanceof Player) ? getServer().getPlayer(args[0]) : null;
                  if (player2 == null) { p.sendMessage("invalid arguments"); return false; }
                    Player player4 = getServer().getPlayer(args[0]);

                    player4.setHealth(0);
 
                    player4.sendMessage("You have been killed by " + p.getName() + ".");
                }
            if(args.length == 0){
                p.setHealth(0);

            }
 
            return true;
        }

        return false;
    }

 

Code:

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



            if(args.length == 0){
                p.setHealth(0);
                return true;
            }
            if(args.length == 1){
                Player player2 = getServer().getPlayer(args[0]);

                player2.setHealth(0);

                player2.sendMessage("You have been killed by " + p.getName() + ".");
            }      

Try that. All I did was added "return true;" below the p.setHealth(0);

 

Thanks It works.

Wounderful Community.

Code:

 return true;

that it was.

//EDIT: Okay here the same Problem, why? I have the Permissions.
//EDIT2: Okay solved. :')

Code:

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


            if (canUseAdminHeal((Player) sender)) {
            String root = "variable.heal";
            String user = args[0];
            Player userp = this.getServer().getPlayer(user);
            if ( args.length == 0 )
            {
                p.setHealth( 20 );
                p.sendMessage( ChatColor.AQUA + "[y00uBasic] Du hast dich geheilt." );
                return true;
            }

            if (args.length == 1) {
                  Player player2 = (getServer().getPlayer(args[0]) instanceof Player) ? getServer().getPlayer(args[0]) : null;
                  if (player2 == null) { p.sendMessage("invalid arguments"); return false; }
                //Player target = (Player) this.getServer().getPlayer( args[0] );
 
                userp.setHealth( 20 );
                userp.sendMessage( ChatColor.AQUA + "[y00uBasic] Du wurdest von " + ((Player)sender).getName() + "geheilt." );
                p.sendMessage("[y00uBasic] Du hast" + userp + "geheilt.");

            }
 
            config.setProperty( root, (healed + 1) );
            config.save();
            } else {
                Player s = (Player) sender;
                s.sendMessage(ChatColor.RED + "You don't have permisson to do that.");
                p.sendMessage("");
            }
            return true;
        }
