Countdown Problems

I was trying to make a countdown from 30 to 0 and when it reaches 0 the game state is set to "started" but the problem is that when it reaches 1, nothing happens next.

Code:

//Counting Down code
    public void start(){
        this.state = ArenaState.COUNTING_DOWN;
        for (Sign s : signs){
            s.setLine(3, getState().toString());
            s.update();
        }

        new Countdown(
                30,
                "Game starting in %t seconds!",
                this,
                30,
                20,
                10,
                5,
                4,
                3,
                2,
                1
                ).runTaskTimer(Elementalers.getPlugin(), 0, 20);
    }

Code:

//The class

    private class Countdown extends BukkitRunnable{
        private int timer;
        private String msg;
        private Arena a;
        private ArrayList<Integer> countingNums;

        public Countdown(int start, String msg, Arena a, int...countingNums){
            this.timer = start;
            this.msg = msg;
            this.a = a;
            this.countingNums = new ArrayList<Integer>();
            for (int i : countingNums) this.countingNums.add(i);
        }

        public void run() {
            if (timer == 0){
                for (PlayerData pd: data){
                    pd.getPlayer().teleport(spawnPoint);
                    cancel();
                }

                MessageManager.getInstance().broadcast(MessageType.GOOD, "The game has started!");
                a.state = ArenaState.STARTED;
            }

            if (countingNums.contains(timer)){
                MessageManager.getInstance().broadcast(MessageType.INFO, msg.replace("%t", timer + ""));
            }

            timer--;
        }
    }

}

 

This^ cancels the task when the for runs so it will terminate the for as well.

 

@mine-care So I should remove them?

 

@Geekhellmc the cancel yes, add it right before the closure of the if.

 

@mine-care Stil nothing changed :/

Code:

        public void run() {
            if (timer == 0){
                for (PlayerData pd: data){
                    pd.getPlayer().teleport(spawnPoint);
                }

                MessageManager.getInstance().broadcast(MessageType.GOOD, "The game has started!");
                a.state = ArenaState.STARTED;
                cancel();
            }

            if (countingNums.contains(timer)){
                MessageManager.getInstance().broadcast(MessageType.INFO, msg.replace("%t", timer + ""));
            }

            timer--;
        }
    }

}

 

Then the only thing you need to do is debug
