startTimer(fiveMinutes, display); However if you want a more accurate timer that is only slightly more complicated: (version with a start/stop button here) var start = Date.now(), diff, minutes, seconds; function timer() {. // get the number of seconds that have elapsed since. // startTimer() was called.

What I want is when the user clicks the start button, it begins and displays the countdown. But although the timer kinda worked, it didn't continuously display the timer when I clicked the button once, instead, I need to click the start button many times to see the countdown number or the timer display will not change. Here's the code.

The timer is neither high-resolution or high-priority. There will be drift - I had to fix this exact bug in code because in CPU-starved situations the drift is painfully noticeable. You need to fetch a start time and calculate remaining time (e.g. by using Date()).

How would I make it so that each element of the countdown is shown in a separate label. So I would have a label that shows the number of days, a label to show the number of hours, a label to show the number of minutes and a label to show the number of seconds.

In standard C# 4 I'd use a System.Windows.Forms.Timer. To start the countdown: var minutes = 3; //countdown time var start = DateTime.UtcNow; // Use UtcNow instead of Now endTime = start.AddMinutes(minutes); //endTime is a member, not a local variable timer1.Enabled = true; In the timer handler you write:

In pygame exists a timer event. Use pygame.time.set_timer() to repeatedly create an USEREVENT. e.g.: timer_interval = 500 # 0.5 seconds timer_event = pygame.USEREVENT + 1 pygame.time.set_timer(timer_event , timer_interval) Note, in pygame customer events can be defined. Each event needs a unique id.

I don't see a way of refreshing the text in a message box. If I had to do this I would probably pop up another form with a label and use a timer that refreshes the text of the label on each tick. Here is a code example to use a potential starting point:

Similar principle as furas's solution already posted, but using a StringVar: import Tkinter def button_countdown(i, label): if i > 0: i -= 1 # schedule next call first to avoid time drifting away from 1s after many calls root.after(1000, lambda: button_countdown(i, label)) label.set(i) else: close() def close(): root.destroy() root = Tkinter.Tk() counter = 10 button_label = Tkinter.StringVar ...

It is simple to countdown with Java. Lets say you want to countdown 10 min so Try this. int second=60,minute=10; int delay = 1000; //milliseconds. ActionListener taskPerformer = new ActionListener() {. public void actionPerformed(ActionEvent evt) {. second--; // put second and minute where you want, or print..

I am trying to create a countdown timer that is in min:sec format which uses a variable taken from a text document and uses it as the finish time and uses the current time (time the .bat was started) as the start time. Currently I have this code which works and gets the time from the text document but I can't seem to figure out how to use get it to work.
