Toggle Players via command

If you are wanting to make a command that will allow you to have your players disable and enable your plugin for them, use this handler. It's fast, safe , and efficient.

Code:

 
  public static Vector<String> disabled_users;
 
 
public static void toggleUser(Player player)
        {
            // make sure the player is real
            if(player == null) { return; }
           
            // initialize vector if not already intialized
            if(disabled_users == null) {  disabled_users = new Vector<String>(); }
           
            // see if the user is already disabled
            int indexOfPlayer = disabled_users.indexOf(player.getName());
            if(indexOfPlayer > -1)
            {
                // remove the player from list
                 disabled_users .remove(indexOfPlayer);
                // tell the player
                player.sendMessage(ChatColor.RED + "------------------ " + ChatColor.GRAY + "" + Main.plugin.Name() + "" + ChatColor.RED + " ---------------------");
                player.sendMessage("  " + ChatColor.GOLD + "You enabled " + Main.plugin.Name() + ".");
            }
            else
            {
                // add the player to the list
                disabled_users .add(player.getName());
                // inform the player
                player.sendMessage(ChatColor.RED + "------------------ " + ChatColor.GRAY + "" + Main.plugin.Name() + "" + ChatColor.RED + " ---------------------");
                player.sendMessage("  " + ChatColor.GOLD + "You disabled  " + Main.plugin.Name() + ".");
            }
        }

Add that to a class such as PlayerManager.class then call it with PlayerManager.toggleUser((Player) sender);

Then just do something such as

Code:

if(PlayerManager.disabled_users.contains(event.getPlayer().getName())
{
//do something
}

 

You should change your Vector to a Set since the order of the players doesn't matter.
Also you can initialize the field directly, you don't have to check whether it is null every time:

Code:

  public final static Set<String> disabled_users = new HashSet<String>();
 
public static void toggleUser(Player player)
        {
            // make sure the player is real
            if(player == null) { return; }
         
            // see if the user is already disabled
            if(disabled_users.contains(player.getName()))
            {
                // remove the player from list
                disabled_users.remove(player.getName());
                // tell the player
                player.sendMessage(ChatColor.RED + "------------------ " + ChatColor.GRAY + "" + Main.plugin.name() + "" + ChatColor.RED + " ---------------------");
                player.sendMessage("  " + ChatColor.GOLD + "You enabled " + Main.plugin.name() + ".");
            }
            else
            {
                // add the player to the list
                disabled_users.add(player.getName());
                // inform the player
                player.sendMessage(ChatColor.RED + "------------------ " + ChatColor.GRAY + "" + Main.plugin.name() + "" + ChatColor.RED + " ---------------------");
                player.sendMessage("  " + ChatColor.GOLD + "You disabled  " + Main.plugin.name() + ".");
            }
        }
