Send message to all players with a certain permission

    I'm attempting to have a plugin I'm making broadcast a message to all players on the server that have a certain permission (like, for example, plugin_name.*, or a child, plugin_name.alert).

    I tried the simple option and went with
    if(player.hasPermission("plugin_name.alert")) {
        player.sendMessage("You'll see this if you have that permission node!");
    However, that appears to not be the way to go about it. So how would I do that? For some reason, I'm thinking of a hashmap of all players that have either of those permissions, but I've read through the bukkit API tutorial. So far what they have there isn't really helping me translate my idea into working code.

    However, I'm not exactly great at Java. If anyone could help, I'd be much obliged.
  2. Code:java
    2. bukkit.broadcast("Message here", "Permission here");

    this will broadcast a message to everyplayer with the your chosen permission

    for(World w : getServer().getWorlds()){
        for(Player p : w.getPlayers()){
    Sorry for typos, made it on my iPad!
  4. you dont need the world for loop just do:
            for(Player p Bukkit.getOnlinePlayers()){

    Yes, but i like it like that, more failproof in my opinion! :)

    Actually, with the loops over all worlds, I imagine more maps being checked, causing a (somewhat) longer processing time.

    Hmm, i make this as a method in my main class, mainly as a broadcastStaff... I have never experienced a longer process time :p

    Nah, it's barely noticable. It's like milliseconds :)

    ^ While everybody was talking about for loops, everyone ignored this guy! ^

    Ah, I had seen the bukkit.broadcast command, but I wasn't aware that you could filter it by permission too. Awesome. Thanks for the help, everyone!

    Oh, but question. If I'm calling this in my playerListener class, as opposed to my main class, how do I tell it what "bukkit" means?

    Just import 'Bukkit' in your class ;)
