Player Login Help

I need help with a PlayerLoginEvent, I have been trying to hide the player that joined from any players that are in my hashset I am unable to figure it out can someone please help me that would be great!

 

You could maybe just remove the Join Message and just send every player thats online in your hash map the join message ??

Maybe something like this ...

Code:

@EventHandler
    public void onJoin(PlayerJoinEvent e){
        e.setJoinMessage(null);
        Player playerjoined = e.getPlayer();
        for(Player p: Bukkit.getOnlinePlayers()){
        if(<arry list name>.contains(p.getName())){
            p.sendMessage(ChatColor.GOLD + playerjoined.getName() + ChatColor.GREEN + " Has Joined The Game!");
        }
        }
    }

 

you could create a for loop, go through all you hashsets players and than hide the player.

 

Could you give me an example CraftBang

 

HashMap<Player> players = new HashMap<Player>();

@EventHandler
public void onPlayerLogin(final PlayerLoginEvent event){
for(Player p : players){
p.hidePlayer(e.getPlayer);
}
}

 

The only thing wrong with that is I don't want the player that logged in to become invisible I only want the players in he Hashset to be invisible

 

e.getPlayer().hidePlayer(p);

 

I know how to hide players I don't know how to make it so if a player is invisible and a differnt player logs in how to make the player who is invisible invisible to the player that just logged in.

 

When a player performs the command that makes the player visible, you have to add the player in a hashmap with "invisiblePlayers.add(player);

HashMap<Player> invisiblePlayers = new HashMap<Player>();

then make a loop that checks the hashmap for all the players

for(Player p : invisiblePlayers){

p is then all the players in the hashmap that is invisible.

e.getPlayer().hidePlayer(p); will make the players in the hashmap invisible for the player that log in to the server.

 

Yeah

 

Doesn't seem to work public ArrayList<Player> hidingPlayers = new ArrayList<Player>(); used this as the player where I store the player then I
@EventHandler
public void onPlayerLogin(PlayerLoginEvent event){
Player player = event.getPlayer();
for(Player p : hidingPlayers){
player.hidePlayer(p);
}

}
and it still didnt seem to work :/
Also seem to be getting alot of error on login
