20 minute countdown timer

Questions & Answers

Hey guys,
I have a countdown timer but am unsure of how to make it twenty minutes?
I would appreciate any help.
Thanks :slight_smile:

public Text timerText;

private float time = 1200;

void Update() {
	time += Time.deltaTime;

	var minutes = time / 60; 
	var seconds = time - 60;
	var fraction = (time * 100) % 100;

	//update the label value
	timerText.text = string.Format ("{0:00} : {1:00} : {2:000}", minutes, seconds, fraction);
}

}

Try the following. It uses less CPU cycles as well.

public Text timerText;
private float time = 1200;

void Start ()
{
    StartCoundownTimer();
}

void StartCoundownTimer()
{
    if (timerText != null)
    {
        time = 1200;
        timerText.text = "Time Left: 20:00:000";
        InvokeRepeating("UpdateTimer", 0.0f, 0.01667f);
    }
}

void UpdateTimer()
{
    if (timerText != null)
    {
        time -= Time.deltaTime;
        string minutes = Mathf.Floor(time / 60).ToString("00");
        string seconds = (time % 60).ToString("00");
        string fraction = ((time * 100) % 100).ToString("000");
        timerText.text = "Time Left: " + minutes + ":" + seconds + ":" + fraction;
    }
}

float totalTime = 120f; //2 minutes

        private void Update()
        {
            totalTime -= Time.deltaTime;
            UpdateLevelTimer(totalTime );
        }

        public void UpdateLevelTimer(float totalSeconds)
        {
            int minutes = Mathf.FloorToInt(totalSeconds / 60f);
            int seconds = Mathf.RoundToInt(totalSeconds % 60f);

            string formatedSeconds = seconds.ToString();

            if (seconds == 60)
            {
                seconds = 0;
                minutes += 1;
            }

            timer.text = minutes.ToString("00") + ":" + seconds.ToString("00");
        }
