The only code is;

Code:

    public void enable(Plugin plugin)
    {
        taskID = Bukkit.getServer().getScheduler().scheduleAsyncRepeatingTask(plugin, new Runnable()
        {
            public void run()
                {
                    for(Player p : Bukkit.getOnlinePlayers())
                    {
                        List<Entity> allEntitys = p.getNearbyEntities(10, 10, 10);
                        System.out.println(allEntitys);
                        if(allEntitys.size() == 0)
                        {
                            System.out.println("Nichts gefunden");
                        }
                        else
                        {
                            for(Entity e : allEntitys)
                            {
                                if(e instanceof Animals)
                                {
                                    List<Entity> allAround = e.getNearbyEntities(50, 10, 50);
                                    if(allAround.size() != 0)
                                    {
                                        for(Entity f : allAround)
                                        {
                                            if(f.getClass() == e.getClass())
                                            {
                                                Animals hey = (Animals) f;
                                                System.out.println(hey);
                                            }
                                        }
                                    }
                                }
                            }
                            System.out.println("Geht");
                        }
                    }
                }
        },100,100);
    }

it is wondering me that it dosen´t throw the error directly ,only after a random amount of time :/

 

If there is noone online... you know he won't find any entities nearby... xD right?

 

It shouldn't run if there is no-one online, I think.

 

When no one is only nothing happen
Only when i join and wait a bit the error appears after some repeats

 

dont use the async task, you creating the bugs byy lakking o fthread safety

 

Not to be rude, but do you write with your toes?

 

Thanks work now

 

I sometimes have times that I type faster than I want and making much of spelling mistakes, but the main part is, he understand it.
