Tasks...

Hi guys, i made a restart script:

Code:java

 if (cmd.getName().equalsIgnoreCase("restart2")) {
          if (sender.hasPermission("tschagg.restarting")) {
            if (args.length == 0) {
                countRestart = 10;
                BukkitTask task = plugin.getServer().getScheduler().runTaskTimerAsynchronously(plugin, new Runnable() {
                        @Override 
                        public void run() {
                            Bukkit.dispatchCommand(Bukkit.getConsoleSender(), "Say Restart in: " + countRestart + "...");
 
                            if (countRestart == 0) {
                                Bukkit.dispatchCommand(Bukkit.getConsoleSender(), "Say Restart Now!");
                                Bukkit.dispatchCommand(Bukkit.getConsoleSender(), "restart now");
                            }
                            countRestart--;
                          }
                    }, 20L, 20L);
            }
          }
      }

2 Questions to it:
Eclipse say me that the task named "task" is unused, how i fix that?
how i cancel this task? i tried task.cancel() but this give me an eclipse error too.

thanks!

 

If there is a message in eclipse saying xyz variable is unused it means that you never use this variable again in your source code.

If you have unused variables, check your code whether you really need them. Otherwise you can use the Annotation: SuppressWarnings

Code:java

 
@SuppressWarnings("unused")
BukkitTask task =.....
 

See also: http://docs.oracle.com/javase/7/docs/api/java/lang/SuppressWarnings.html

If you would not use the variable "task" anymore you also can write it like this:

Code:java

 
plugin.getServer().getScheduler().runTaskTimerAsynchronously(plugin, new Runnable() { .... }
 

But you need it again to cancel your task so:

Code:java

 
plugin.getServer().getScheduler().cancelTask(task.getTaskId());
 

 

what is the eclipse 'error' when you try to invoke the cancel() method
