I started using pygame and I want to do simple game. One of the elements which I need is countdown timer.
How can I do the countdown time (eg 10 seconds) in PyGame?
Another easy way is to simply use pygame's event system.
Here's a simple example:
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)
On this page you will find what you are looking for http://www.pygame.org/docs/ref/time.html#pygame.time.get_ticks
You download ticks once before beginning the countdown (which can be a trigger in the game - the key event, whatever).
For example:
start_ticks=pygame.time.get_ticks() #starter tick
while mainloop: # mainloop
seconds=(pygame.time.get_ticks()-start_ticks)/1000 #calculate how many seconds
if seconds>10: # if more than 10 seconds close the game
break
print (seconds) #print how many seconds
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. The ids for the user events have to be between pygame.USEREVENT (24) and pygame.NUMEVENTS (32). In this case pygame.USEREVENT+1 is the event id for the timer event.
To disable the timer for an event, set the milliseconds argument to 0.
Receive the event in the event loop:
running = True
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
elif event.type == timer_event:
# [...]
The timer event can be stopped by passing 0 to the time parameter.
See the example:
import pygame
pygame.init()
window = pygame.display.set_mode((200, 200))
clock = pygame.time.Clock()
font = pygame.font.SysFont(None, 100)
counter = 10
text = font.render(str(counter), True, (0, 128, 0))
timer_event = pygame.USEREVENT+1
pygame.time.set_timer(timer_event, 1000)
run = True
while run:
clock.tick(60)
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
elif event.type == timer_event:
counter -= 1
text = font.render(str(counter), True, (0, 128, 0))
if counter == 0:
pygame.time.set_timer(timer_event, 0)
window.fill((255, 255, 255))
text_rect = text.get_rect(center = window.get_rect().center)
window.blit(text, text_rect)
pygame.display.flip()
pygame.time.Clock.tick returns the time in milliseconds since the last clock.tick call (delta time, dt), so you can use it to increase or decrease a timer variable.
import pygame as pg
def main():
pg.init()
screen = pg.display.set_mode((640, 480))
font = pg.font.Font(None, 40)
gray = pg.Color('gray19')
blue = pg.Color('dodgerblue')
# The clock is used to limit the frame rate
# and returns the time since last tick.
clock = pg.time.Clock()
timer = 10 # Decrease this to count down.
dt = 0 # Delta time (time since last tick).
done = False
while not done:
for event in pg.event.get():
if event.type == pg.QUIT:
done = True
timer -= dt
if timer <= 0:
timer = 10 # Reset it to 10 or do something else.
screen.fill(gray)
txt = font.render(str(round(timer, 2)), True, blue)
screen.blit(txt, (70, 70))
pg.display.flip()
dt = clock.tick(30) / 1000 # / 1000 to convert to seconds.
if __name__ == '__main__':
main()
pg.quit()

time_left = 90 #duration of the timer in seconds
crashed = False
font = pygame.font.SysFont("Somic Sans MS", 30)
color = (255, 255, 255)
while not crashed:
for event in pygame.event.get():
if event.type == QUIT:
crashed = True
total_mins = time_left//60 # minutes left
total_sec = time_left-(60*(total_mins)) #seconds left
time_left -= 1
if time_left > -1:
text = font.render(("Time left: "+str(total_mins)+":"+str(total_sec)), True, color)
screen.blit(text, (200, 200))
pygame.display.flip()
screen.fill((20,20,20))
time.sleep(1)#making the time interval of the loop 1sec
else:
text = font.render("Time Over!!", True, color)
screen.blit(text, (200, 200))
pygame.display.flip()
screen.fill((20,20,20))
pygame.quit()
sys.exit()
This is actually quite simple. Thank Pygame for creating a simple library!

I'm having a hard time with pygame blitting text onto the screen. Right now before quitting I just want to have a message show up for 2 seconds, then have the game quit. To do this I use time.sleep(2). However, and I believe most other people don't have this issue from questions I've looked up on Stackoverflow, the text just doesn't show up until what seems to be the last moment before the window closes. Rather, the screen remains white after pressing the close button. My code is below. Please note that this is not a duplicate of this question.
import pygame
import time
pygame.init()
white = (255,255,255)
black = (0,0,0)
red = (255,0,0)
display_width = 800
display_height = 600
gameDisplay = pygame.display.set_mode((display_width,display_height))
clock = pygame.time.Clock()
FPS = 30
font = pygame.font.SysFont(None, 25)
x = False
while not x:
for event in pygame.event.get():
if event.type == pygame.QUIT:
x = True
gameDisplay.fill(white)
pygame.display.update()
clock.tick(FPS)
screen_text = font.render('Test', True, red)
gameDisplay.blit(screen_text, (0, 0))
pygame.display.update()
time.sleep(2)
pygame.quit()
I ended up using the pygame.time.set_timer workaround #CodeSurgeon mentioned.
This worked for me - replacing time.sleep(2), with:
pygame.time.set_timer(pygame.USEREVENT, 2000)
should_quit = False
while not should_quit:
for event in pygame.event.get():
if event.type == pygame.USEREVENT:
should_quit = True
I actually have the exact same problem and found that if I moved time.sleep(2) directly after pygame.quit() it worked as intended. I'm new to pygame and not sure why this works
screen_text = font.render('Test', True, red)
gameDisplay.blit(screen_text, (0, 0))
pygame.display.update()
pygame.quit()
time.sleep(2)
You could try replacing time.sleep(2) with
for i in range(0, 200, 1):
time.sleep(0.01)
This can be useful in other situations with long sleeps if you want to be able to use CTRL-C to stop the program. It also might be more convenient to use a function:
def MySleep(duration, resolution=10):
"""Sleep, without freezing the program. All values in ms"""
for i in range(0, int(duration), int(resolution)):
time.sleep(resolution / 1000)
for some reason, stdlib time.sleep() does not work in pygame.
However, pygame does have its own time function.
Here is the code I wrote to print out a message, character by character.
message = ""
font = pygame.font.Font("freesansbold.ttf", 32)
message_text_x = 0
message_text_y = 550
message_text_speed = 35
inF = open("chapter_1.txt")
lines = inF.readlines()
def write_message(char, x, y):
# first render the value as text so it can be drawn on the screen using screen.blit
message_text = font.render(char, True, (0, 0, 0))
screen.blit(message_text, (x, y))
running = True
while running:
for line in lines:
for char in line:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_q:
running = False
if event.key == pygame.K_SPACE:
message_text_speed = 10
message += char
write_message(message, message_text_x, message_text_y)
pygame.event.pump()
pygame.time.delay(message_text_speed)
pygame.display.update()
clock.tick(60)
When spacebar is clicked the speed of the text becomes faster

The best way to do this would be to make them into classes and give them a run method, and then instantiate each one on a timer and call its run method to do what it needs to do.
