Timers

Hey,

I want to create a timer like this.

Timer that loops every seconds
{
if (seconds == 0)
{
//stop timer
}
seconds--;
}

How can I do this the best way? I like to have it in the same class, but it's not a problem if thats not possible or something

 

Use a BukkitRunnable :- )
http://wiki.bukkit.org/Scheduler_Programming

 

Moved to Plugin Development,

 

@mine-care
Thanks, but which one on that page should I use, cause I don't find it really clear, which one repeats and I can cancel inside the runnable (if heard several problems with that when I was looking for this).

 

@stefvanschie use an int outside the runnable with the times it should repeat (or seconds) then everytime the runnable goes the int will decrease by 1. then when it reaches 0 you can cancel the event from within.. what I did in such situations is a delayed task and I recall the method if it needs to be repeated and just don't recall when it ends. don't forget to decrease the value of the int each time with the task otherwise you have an infinite loop.

 

@guitargun That's a usefull trick! Didn't think of that, but I'll try tomorrow. I have good hope.

It doesn't remove the seconds and it starts at zero, while in my config it says timer: 300
What am I doing wrong here?

Code:

   
int seconds = config.getInt("timer");
public void timer()
    {
        BukkitScheduler scheduler = Bukkit.getServer().getScheduler();
        scheduler.scheduleSyncDelayedTask(this, new Runnable()
        {
            @Override
            public void run()
            {
                Bukkit.broadcastMessage(seconds + "");
                if (seconds == 60 || seconds == 30 || seconds == 15 || (seconds >= 1 && seconds <= 10))
                {
                    for (Player pl : players)
                    {
                        pl.sendMessage(ChatColor.GOLD + "You have " + seconds + " seconds left!");
                    }
                }
                else if (seconds == 0)
                {
                    for (Player pl : players)
                    {
                        pl.sendMessage(ChatColor.GOLD + "The time to build is over!");
                    }
                    String worldstr = arenas.getString("main-spawn.world");
                    World world = getServer().getWorld(worldstr);
                    int x = arenas.getInt("main-spawn.x");
                    int y = arenas.getInt("main-spawn.y");
                    int z = arenas.getInt("main-spawn.z");
                    Location location = new Location(world, x, y, z);
                    players.clear();
                    for (Player pl : players)
                    {
                        pl.teleport(location);
                        pl.sendMessage(ChatColor.GOLD + "Game done!");
                    }
                    players.clear();
                }  
                seconds--;
                timer();
            }
        }, 20L);
