    Code:java
    1. if(player.getLocation().getWorld().getName().toLowerCase().equals("MyWorldName")){
    2.     player.sendMessage("You are in MyWorldName!");
    3. }

    The only way I can think of is to iterate through getOnlinePlayers() and check their world.

    Would you know how to get a list of worlds from a config file?

    structured like

    Code:
    Worlds:
  world
  world_nether
    etc

    And tell the player the listed worlds?

    Btw, I was the one to first suggest it :p
    But to get from config, use
    Code:java
    1. List<String> myList = getConfig().getStringList("Path.To.List");
    and your config.yml would look like:
    Code:
    Path:
  To:
    List:
      - world
      - world_nether
    To tell the player all the world in the list:
    Code:java
    1. String myListString = "";
    2. for(String world : myList){
    3.    myListString += " " +world;
    4. }
    5. player.sendMessage("The worlds are:" + myListString);

    To get it from a file you have to create a YAML interface. You can also get all the worlds on the server in a list Bukkit.getServer().getWorlds().

    Code:
    for(Player p : someWorld.getPlayers()) {
  p.sendMessage("hello");
}

    You did .toLowerCase() and then compared it with something that isn't lowercase...which will always return false.
    It should be
    Code:java
    1. if(player.getWorld().getName().equals("MyWorldName"))

    Here you go:

    Code:java
    1.     static void msgWorld(Player player, String msg)
    2.     {
    3.         World w = player.getWorld();
    4.         for (Player players : Bukkit.getServer().getOnlinePlayers())
    5.         {
    6.             String name = players.getName();
    7.             if(players.getWorld() == w)
    8.                 players.sendMessage(msg);
    9.         }
    10.     }
    11.  
    12.     static void msgWorld(String world, String msg)
    13.     {
    14.         World w = Bukkit.getWorld(world);
    15.         for (Player players : Bukkit.getServer().getOnlinePlayers())
    16.         {
    17.             String name = players.getName();
    18.             if(players.getWorld() == w)
    19.                 players.sendMessage(msg);
    20.         }
    21.     }


    I can't edit my message but I made some better code so here it is;

    Code:java
    1.     static void msgWorld(Player player, String msg)
    2.     {
    3.         World w = player.getWorld();
    4.         for(Player p : w.getPlayers())
    5.         {
    6.             p.sendMessage(msg);
    7.         }
    8.     }
    9.  
    10.     static void msgWorld(String world, String msg)
    11.     {
    12.         World w = Bukkit.getWorld(world);
    13.         for(Player p : w.getPlayers())
    14.         {
    15.             p.sendMessage(msg);
    16.         }
    17.     }

    How would i do this per world?, as i have tried but am out of ideas.

    Do what per world, exactly??

    And they all gave you helpful ways to get the world.

    Instead of all the replaceAll stuff you can just do this:
    Code:java
    1. line = ChatColor.translateAlternateColorCodes('&', line);
    2. ann = ChatColor.translateAlternateColorCodes('&', ann);


    Second, you've already been given the code to broadcast messages to players in specific worlds.

    I want it to get from a message<worldname>.txt (and create the txt if it doesnt exist) and broadcast those messages to people in that specific world, but im having problems on how to figure this out.

    I'm getting no errors from the current code, it broadcasts it to all worlds. But when trying to figure out how to make it different per world, i get stuck trying to figure it out.

    Honestly, I would use a YAML file instead of a TXT file for that kind of stuff. Just personal preference.

    And many people previously told you how to do it in several different ways.

    Where are you posting this code, exactly? The more you actually tell us the less I have to ask these questions and the faster the issue can be resolved, hopefully.

    Where exactly are you trying to get the worlds?

    And by the way, your lines 106-141 or so can be summed up in one or 2 lines (read up someone already mentioned it).

    Yes i fixed that.

    I haven't implemented getting worlds, as i don't understand how. Also making a int for each world? So that it can count the lines in the messages<worldname>.txt etc? I don't understand how to do this.

    Thanks,

    Dablakbandit Post your new code again. As I asked before, why are you using a text file? Use a YAML file instead.

    I'm sorry for sounding like an ass, but what's wrong with a YAML? It's a lot easier to use, and instead of calling all those methods with the .txt, you could just make a config.yml.

    Can this just be solved please? I asked how to configure my code for per world, not how to use a YAML file for it.

    Thanks,

    While you didn't ask for it, I was just trying to give you a suggestion.
    Hopefully someone else can help you, because I am unfamiliar with using txt files, in any case.
    And only you can set it to solved :)
