Cancel a BukkitRunable

Hii,
I got an issue on my plugin. I don't know how to stop an event when a player leave an arraylist.
Can anyone help me?

Code:

public class Start extends BukkitRunnable implements Listener{
  
    private int timerstart = 10;
    private Main main;
  
    public Start(Main main) {
        this.main = main;
    }
  
    @Override
    public void run() {
      
        for(Player pls : main.getPlayers()) {
            pls.setLevel(timerstart);
        }
        if(main.getPlayers().size() <= 1) {
        Bukkit.getScheduler().cancelTasks(main);
        }
      
        if(timerstart == 10 || timerstart == 5 || timerstart == 4 || timerstart == 3 || timerstart == 2 ) {
            Bukkit.broadcastMessage("Le jeu démarre dans " + timerstart + " secondes");
            Bukkit.getOnlinePlayers().forEach(t -> t.sendTitle("Le jeu commence dans", timerstart + " secondes"));
          
        }
        if(timerstart == 1) {
            Bukkit.broadcastMessage("Le jeu démarre dans " + timerstart + "seconde");
            Bukkit.getOnlinePlayers().forEach(t -> t.sendTitle("Le jeu commence dans", timerstart + " seconde"));
        }
      
      
        if(timerstart == 0) {
            if(main.getPlayers().size() == 2) {
            Bukkit.broadcastMessage("Lancement du jeu");
            main.setState(Status.SEARCHING);
            cancel();
              
            }

        }
      
        timerstart --;
    }
  

}

Can anyone help me ?

 

Try checking at intervals if the player is still there, if not cancel the bukkitrunnable. To cancel it:
you save the return value of runTaskTimer (which is a BukkitTask) in a variable and call the cancel() method.

Also looking at your code, shouldn't you jsut have a PlayerQuitEvent somewhere that will automatically remove the player from arraylist?

Or am I not understading your problem? Please elaborate.

 

Maybe you can use "your-arraylist.contains(player)" to judge whether a player is still in the list. Then use"this.cancel()"
to cancel the task which the code in. Or use task.cancel() to cancel other bukkit tasks. (task = other bukkit task /runable)
