Player's syncRepeatingTask

Hello Everyone,

I have a question,
I want to create a syncrepeatingtask when a player joins. So for example:

- Player1 joins
- Creates syncrepeatingtask with name: "Player1repeatingtask"
- Player2 joins
- Creates syncrepeatingtask with name: "Player2repeatingtask"
- Staartvin joins
- Creates syncrepeatingtask with name: "Staartvinrepeatingtask"

Something like that. Is this possible? If so, could you be so kind to tell me?

Thank you in advance,
Staartvin

 

Of course it is. Just start a new one I'm just not sure how you want to name the threads, because the only thing you can get back is an int, representing the Bukkit Thread ID for that thread.

 

That's the problem. I know Java can do this, but I don't know how. I thought it was called Dynamic Programming where the value of an object is the name you can create things with. The problem is I can't find any tutorials about it, nor do I understand them So I hope for more luck!

 

You can't use names, so save the int (id of the task) for your specific player using a HashMap.

 

Code:java

LookItsATask task = new LookItsATask(plugin, player.getName());
task.setPid(plugin.getServer().getScheduler().scheduleSyncRepeatingTask(task, 20L, 20L));

Code:java

public class LookItsATask implements Runnable
{
    private final YourPlugin plugin;
    private final String name;
    private int pid;
    private count = 0;
 
    public LookItsATask(YourPlugin plugin, String name)
    {
        this.plugin = plugin;
        this.name = name;
    }
 
    public void setPid(int pid)
    {
    this.pid = pid;
    }
 
    public Player getPlayer() // Just in case you want to use the class out of the BukkitScheduler, too, and need to get the name...
    {
    return plugin.getServer().getPlayerExact(name);
    }
 
    public void run()
    {
        Player player = getPlayer();
        if(player == null)
            plugin.getServer().getScheduler().cancelTask(pid);
        else
            player.sendMessage("You're online for "+(++count)+" seconds now!");
    }
}

Where's the problem...?

 

Yeah.. That doesn't work. I get error in Eclipse about here:

LookItsATask task = new LookItsATask(plugin, player.getName());
task.setPid(plugin.getServer().getScheduler().scheduleSyncRepeatingTask(task, 20L, 20L));

 

What error and where exactly? <.<

 

Whoops forgot to mention error, Sorry!


Error:

The method scheduleSyncRepeatingTask(Plugin, Runnable, long, long) in the type BukkitScheduler is not applicable for the arguments (Broadcaster.LookItsATask, long, long)
at:

task.setPid(plugin.getServer().getScheduler().scheduleSyncRepeatingTask(task, 20L, 20L));

 

so change it to
task.setPid(plugin.getServer().getScheduler().scheduleSyncRepeatingTask(plugin, task, 20L, 20L));
...

 

It gives me a nullpointer.. on this line:
task.setPid(plugin.getServer().getScheduler().scheduleSyncRepeatingTask(plugin, task, 20L, 20L));

What could be null?

plugin is null.
Remove this:

Code:java

private Broadcaster plugin;

this:

Code:java

public void Players2(Broadcaster plugin)
{
this.plugin = plugin;
}

and change every "plugin." to "this."
