getWorld() Problems

Hi guys, I am having a little bit of trouble with a plugin i am making. Can someone please tell me the code to list players in THEIR world only if they type a command. Thanks

 

Create a new HashMap with key type String, and object type List<String>
Then when you wand to add the player, you can do something like this:

List<String> l = map.get(player.getWolrd().getName());
l.add(p.getName());
map.put(l);

Code:java

public Set<Player> getPlayersInWorld(Player player) {
 
    Set<Player> players;
 
    players = new HashSet<Player>();
 
    for(Player comparingPlayer:Bukkit.getOnlinePlayers()) {
 
        if(!player.equals(comparingPlayer) &&
                player.getWorld().equals(comparingPlayer.getWorld())) {
 
            players.add(comparingPlayer);
        }
    }
 
    return players;
}

 

Amgis It's just getWorld().getPlayers(). I don't see what you're all going on about.

I was under the impression that he wanted a list of players in the same world as a player but not including the player himself.

 

Amgis Then World#getPlayers().remove((Player) sender);. It's not that hard.

I see. Thanks for the correction.

Code:java

public List<Player> getPlayersInWorld(Player player) {
 
    List<Player> players = player.getWorld().getPlayers();
 
    players.remove(player);
 
    return players;
}

 

You shouldn't be storing players, use their names!
It can create a massive memory leak!

Only if not dealt with correctly

 

Chances are, most people aren't going to know that they have to unload all the data on disconnect...
