    So i got a class where i have a method which needs to cancel a runnable in another class thats in a method.

    This is the code with the runnable.
    public void onDeathCheck(final String ar){
            final ArrayList<UUID> listofplayer = new ArrayList<UUID>();
            final BukkitScheduler scheduler = Bukkit.getServer().getScheduler();
            scheduler.scheduleSyncRepeatingTask(main, new Runnable() {
                public void run() {
                    for (Entry<UUID, String> entry :
                    if(listofplayer.size() == 1){
                        if(listofplayer.size() == 1){
                            UUID uuid = listofplayer.get(0);
                               for(Player player : Bukkit.getServer().getOnlinePlayers()){
                                       String arenaname =;
                                       World world = Bukkit.getWorld(main.arenas.getString("arenas." + arenaname + "." + ""));
                                       Location loc = new Location(world, main.arenas.getDouble("arenas." + arenaname + "." + "egg.X")
                                            ,main.arenas.getDouble("arenas." + arenaname + "." + "egg.Y"),
                                            main.arenas.getDouble("arenas." + arenaname + "." + "egg.Z"));
                                       player.sendMessage(ChatColor.GREEN + "You are the last man standing! You have been teleported to claim your prize!");
            } , 0L, 20L);
    I made the class accesable via the main.
    Any idea how i would cancel this ?
  2. @MinecraftMart Store the Runnable number in a list. (Or a Map). Then you can use Bukkit.getScheduler().cancelTask(id);

    Huh? the above makes no sense, its like saying:
    Object a =...;
    if(a is an apple){
    //here you are sure it is an apple
    if(a is an apple){
    //here you check again if it is an apple. this is a pointless if :p


    Also why you create a clone of the arraylist in the method?
    get a set of keys as: Set ... = map.keySet();

    Aah thanks, ill check this out yeah.
    But what if more instances of the method are created?
    Like lets say i call the method twice?

    That if thing is a mistake xD and the player map has more players with a different var. the listofplayers is a list with 1 var. And for now i dont know a good way to check if the number of keys with a val equals 1. So yeah.. xD Im still learning. But so far i made an awesome lot of progress for an awesome plugin.

    @MinecraftMart Good. To fix the above prob, read about lists & maps. it normally takes about 10-20 minutes :p

    You mean the problem with listofplayers or my main problem?

    Don't store an int from scheduleTask(etc), use .runTaskTimer or similar methods, and store the BukkitTask object that is returned. Then call cancel() on that object.
