How to Create a Countdown Timer in Pygame?

Countdown Timers in Pygame

Pygame is a popular library for creating games in Python. One useful feature to include in games is a countdown timer. This can be achieved using several methods, one of which employs Pygame's event system.

Example:

Here's a simple example of creating a countdown timer in Pygame:

import pygame
pygame.init()
screen = pygame.display.set_mode((128, 128))
clock = pygame.time.Clock()

counter, text = 10, '10'.rjust(3)
pygame.time.set_timer(pygame.USEREVENT, 1000)
font = pygame.font.SysFont('Consolas', 30)

run = True
while run:
    for e in pygame.event.get():
        if e.type == pygame.USEREVENT: 
            counter -= 1
            text = str(counter).rjust(3) if counter > 0 else 'boom!'
        if e.type == pygame.QUIT: 
            run = False

    screen.fill((255, 255, 255))
    screen.blit(font.render(text, True, (0, 0, 0)), (32, 48))
    pygame.display.flip()
    clock.tick(60)

This code sets up a 10-second countdown timer and displays the remaining time in a text box. The pygame.USEREVENT event is used to trigger the countdown and decrement the counter. The counter is then formatted and displayed on the screen. When the counter reaches zero, the text "boom!" is displayed instead.
