Problems with the "PlayerLoginEvent"

Hello,
I try to display a message when a player joins the server:

PHP:

    public void onPlayerLogin(PlayerLoginEvent event)
    {
        System.out.println("USER JOIN!");
         Player player = event.getPlayer();
        player.sendMessage(ChatColor.GREEN + "Hello, " + player.getDisplayName());
        player.sendMessage(ChatColor.GRAY + "Currently online: " + onlineUser());
    }
...
    private String onlineUser()
    {
        String onlineuser = "";
        for(Player p : plugin.getServer().getOnlinePlayers())
        {
            onlineuser += p.getDisplayName() + ",";
        }
        onlineuser = onlineuser.substring(0,onlineuser.length()-1);
        return onlineuser;
    }


But I always have an error if I join. I receive the Test ("USER JOIN!") but I can't deal with the Userdata.
Can anyone help me?

 

Can you give a little bit more of an explanation so i know what your talking about?

 

Yes, of course:
I want to display a motd if the player joins the game.
But if I try to send to him a message I receive the following exception:

Now I want to know: How can I send the player a message if he joined the game?

 

You personally or the server does it automatically?

 

AFAIK you can't. PLAYER_LOGIN is done before the actual joining the game. You can use PLAYER_JOIN wich is sent later.

 

That is true.

 

But PLAYER_JOIN isn't implemented yet, is it?

 

yes it is.

 

It is even in the javadocs.

 

I see. Thanks.

 

PLAYER_LOGIN is "this player is logging in, can they join or are they banned?".

 

Okay, thanks.
I just was wondering, why I couldn't send them a message
