Setting scoreboard to one player equals all players in the server?

Hello, I am doing that simple checking and setting the scoreboard, but it still sets to everyone in the server...

Code:

            for (Player onlinePlayers : Bukkit.getOnlinePlayers()) {
                if (onlinePlayers.getWorld() == Bukkit.getWorld("arena")) {
                    onlinePlayers.setScoreboard(plugin.Scoreboard1);
                }
            }

 

use .equals instead of ==

 

Thanks, but it didn't affect anything. :/
Current code:

Code:

           for (Player onlinePlayers : Bukkit.getOnlinePlayers()) {
               if (onlinePlayers.getWorld().equals(Bukkit.getWorld("arena")))) {
                   onlinePlayers.setScoreboard(plugin.Scoreboard1);
               }
           }

 

The for loop will return ALL online players, not just one player. If you want ONE player, create a player object. Also, checking to see what world they are in, won't affect that the for loop calls ALL online players on the server... So thats why @FishyLP's suggestion didn't change.

 

@OfficerDeveloper
... Youre not right I think
He looped through every onlinePlayer.
Then he checked if the current Player in the loop is in the world. The code after it will only run, if the if-condition is true

 

Compare the world name instead.

 

@IconByte Do what @RainoBoy97 said. You need to do player.getWorld().getName

 

@FisheyLP I am right, that check will return all the players in that world, not one specific player. So thats why it is not working the way he wants it to.
