Create Timer & Point System

Hello Everybody, i am MineoxFX and i am wondering how i can create a timer that when the server reaches its maximum player limit a Timer start from 120 seconds to 0 and it broadcasts how much time is left when in: 2 minutes, 1 minute, 30 seconds, 15 seconds, 10 seconds, 5 seconds, 4 seconds, 3 seconds, 2 seconds and 1 second.

i Have this code:

Code:java

this.getServer().getScheduler().scheduleSyncDelayedTask(this, new Runnable() {
 
public void run() {
your code here
}
}, 60L);// 60 L == 3 sec, 20 ticks == 1 sec

But i dont know how to implement it.

Also i am trying to create a Poin system using the scoreboard i think this can be done using 'dummy' but i really dont know.

Regards and Thanks in Advance,
Mineox

 

Code:java

public void startCountdown() {
        countdown = 120;
        countdownTask = new BukkitRunnable() {
 
            @Override
            public void run() {
                switch (--countdown) {
                case 10:
                case 5:
                case 4:
                case 3:
                case 2:
                case 1:
                    // Do what you want on 10,5,4,3,2,1 seconds left
                    break;
                case 0:
                    this.cancel();
                    // Do whatever you want if the countdown is over
                    break;
                default:
                    if(countdown % 15 == 0) {
                        // Do something every 15 seconds
                    }
                    break;
                }
            }
        }.runTaskTimer(CaptureTheFlag.getPlugin(), 20, 20);
    }

 

Thanks but what is: }.runTaskTimer(CaptureTheFlag.getPlugin(), 20, 20);
And that wont start when the server is full

 

CaptureTheFlag.getPlugin() is my plugin reference.

runTaskTimer(Plugin, delay, repeat);

Run first after delay and repeat every repeat ticks.
