Solved Help with code!

Why does it crash the server?

Code:java

Any stack trace of an error?
And why are you cancelling the task of id num? what is num exactly as you seem to be decreasing it all the time?

 

just gonna throw this out there, it looks like your canceling a task for the integer num, but then in a different scheduler your changing num around.

Code:

 
this.getServer().getScheduler().runTaskLater(this, new Runnable()
{
 
public void run()
{
bluep.getServer().getScheduler().cancelTask(num); <--- HERE
bluep.getInventory().clear();
restoreInventory(bluep);
 
}
 
}, 10000);
 
this.getServer().getScheduler().scheduleAsyncRepeatingTask(this, new Runnable()
{
 
public void run()
{
if(num != -1)
{
if(num != 0)
{
Location bl = bluep.getLocation();
bluep.getPlayer().getWorld().playEffect(bl, Effect.MOBSPAWNER_FLAMES, 1);
num--; <--- HERE
}
else
{
bluep.getServer().getScheduler().cancelTask(num);
bluep.getWorld().setTime(1000);
num--; <--- HERE
}
}
 
}
}, 0L, 10L);

you may also want to use BukkitRunnables. try using this for timers

Code:

new BukkitRunnable() {
@Override
public void run() {
}
}.runTaskTimer(this, 0L, 10L);

The only difference as far as i can tell is that the BukkitRunnable class provides some methods to run a Runnable with the bukkit scheduler. https://github.com/Bukkit/Bukkit/bl...java/org/bukkit/scheduler/BukkitRunnable.java

 

The problem was probably that you were using an Async task instead of a Sync task

 

Now when launch the start command it crashes the server

EnderPilot105
What is the start command exactly? And what errors do you get at crash?
Btw, I suggest you cancel the repeating task once it has finished what it should do.

 

This. Use .scheduleSyncRepeatingTask instead of .scheduleAsyncRepeatingTask

 

Problem: The console stops working and just freezes, the server freezes too there are no errors

How can you stop a tasks?

When you create the task, the function returns an object of the task. Store that in a global static(?) variable (haven't used tasks in a long time) and then when the task is done doing it's job, do a cancel function on that object.

Since the server freezes along with the console, I believe that it's either stuck on a VERY long loop, maybe a Thread.sleep, or out of memory

 

This, except the variable should not be static nor global unless it absolutely must be. If you're cancelling the task from the same class as you created it, you can just store its ID in a private variable.

 

I have made progress it crashes with error - doesnt freeze!
I changed the runnable() to BukkitRunnable()
and .scheduleSyncRepeatingTask to .scheduleAsyncRepeatingTask
it says null pointer exeption coasterman10 alex123099 Traks

 

Please post error and full code and/or on what line the null pointer occurs, also don't use async tasks when you use Bukkit methods in them

 

I ment AsyncTask to synctask

What is on line 826 of the Youtube class?

 

EnderPilot105
Your isset list is null

 

a.sendMessage("" + ChatColor.GREEN + "<Battle Dome> "

 

I fixed the problem - i was setting the potion effects amplifier and duration to Integer.MAX_VALUE
