Solved How to get ID of a specific Sync Task?

I need to find the ID of the task that has a 600 tick delay, none of the others, so that I can remove that task if there are no players in that arena. Here's the code:

Code:

for(int derpy = 5; derpy <= 600; derpy += 5)
                                {
                                    final int de = derpy;
                                    Bukkit.getServer().getScheduler().scheduleSyncDelayedTask(this, new Runnable()
                                    {
                                        @Override
                                        public void run()
                                        {
                                            if(players.get(arenaname) == 0)
                                            {
                                                Bukkit.getScheduler().cancelAllTasks();
                                            }else
                                            {
                                                    for(int x = 660; x <= 710; x++)
                                                    {
                                                        for(int y = 220; y <= 270; y++)
                                                        {
                                                            for(int z = 461; z <= 511; z++)
                                                            {
                                                                Location loc = new Location(Bukkit.getWorld("world"), x, y, z);

                                                                    Sign s = (Sign) loc.getBlock().getState();
                                                                    if(s.getLine(1).equalsIgnoreCase(arenaname))
                                                                    {

                                                        }
                                                    }
                                                if(de == 600)
                                                {

                                        }
                                    }, derpy);
                                }

 

Make an int like "int task;" and then do

Code:

public class Test extends JavaPlugin implements Listener {
   
    int task;
 
    @Override
    public void onEnable() {
        PluginManager pm = this.getServer().getPluginManager();
 
        pm.registerEvents(this, this);
       
        task = Bukkit.getServer().getScheduler().scheduleSyncDelayedTask(this, new Runnable()
        {
            @Override
            public void run()
            {
                if(somthing){
                    Bukkit.getScheduler().cancelTask(task);
                }
            }
        }, 0L);
    }
 
    @Override
    public void onDisable() {
       
       
    }

 

Burnett1 Oh ok, I'm trying it now.

 

piano9uber
Bukkit has a new way of doing tasks. Instead of what Burnett1 suggested, create a BukkitTask and use runTaskLater or runTaskTimer.

Code:

BukkitTask task = getServer().getScheduler().runTaskLater(this, new Runnable() {
    @Override
    public void run() {
        // task
    }
}, 1L);

task.cancel() will cancel the task.

 

hockeygoalie5 Thanks! I got it fixed.
