I'm trying to pause my game by pressing the 'p' key, but after it pauses it does not unpause when p is pressed again. Here are the relevant segments of my code, I'd like to know how to fix this and/or if there are better alternative methods of implementing a game pause.
pause = False
while True:
if not pause:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
#game code
keys = pygame.key.get_pressed()
#if key up
elif keys[pygame.K_p]:
pause = True #appears to work correctly, screen freezes and
#prints "PAUSED" every tick.
#more game code
pygame.display.update()
fpsClock.tick(FPS)
else:
print("PAUSED")
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
elif event.type == pygame.KEYDOWN:
if event.type == pygame.K_p:
pause = False
pygame.display.update()
fpsClock.tick(FPS)
The code below does the trick.
I have added in if not pause: ... else: section also a handler for a keypress because without it there will be no chance to come out of the pause (the part if not pause won't never ever be run without this keypress check if once paused).
import pygame
pygame.init() # start PyGame (necessary because 'import pygame' doesn't start PyGame)
colorWhite = (255, 255, 255) # RGB color for later use in PyGame commands (valueRed=255, valueGreen=255, valueBlue=255)
colorWhite = (255, 255, 255) # RGB color for later use in PyGame commands (valueRed=255, valueGreen=255, valueBlue=255)
winDisplay = pygame.display.set_mode((1024, 768)) # set PyGame window size to 1024x768 pixel
pygame.display.set_caption("Minimal PyGame Test Script")
winDisplay.fill(colorWhite)
fpsClock = pygame.time.Clock()
FPS = 15
pause = False
pauseCounter = 0
while True:
if not pause:
for event in pygame.event.get():
if event.type == pygame.KEYDOWN and event.key == pygame.K_p:
pause = not pause
#game code
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
#more game code
pygame.display.update()
fpsClock.tick(FPS)
else:
pauseCounter += 1
print(pauseCounter, "PAUSED")
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
if event.type == pygame.KEYDOWN and event.key == pygame.K_p:
pause = not pause
#more game code
pygame.display.update()
fpsClock.tick(FPS)

My pygame project consists of several parts, including global map and towns. I use one Game class to contain necessary objects. All game is shown on one screen and works properly with global map and town (in_city function), it changes the screen and shows necessary information, but when I call another function (buy), it doesn't update screen.
def buy(self):
while self.running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
self.running = False
if event.type == pygame.KEYDOWN:
return
self.screen.fill('BLACK')
pygame.display.update()
pygame.display.flip()
def in_city(self):
while self.running:
stop = False
for event in pygame.event.get():
if event.type == pygame.QUIT:
self.running = False
if event.type == pygame.MOUSEMOTION:
all_sprites.update(pygame.mouse.get_pos())
if event.type == pygame.MOUSEBUTTONDOWN:
mouse_pos = pygame.mouse.get_pos()
button_right.click(mouse_pos)
button_left.click(mouse_pos)
button_next.click(mouse_pos)
button_prev.click(mouse_pos)
if button_close.on_button(mouse_pos):
stop = True
if event.type == pygame.KEYDOWN:
self.buy()
if stop:
self.player.route = [(0, 0)]
self.player.next_move(self.maps)
self.camera.update(self.player)
return
screen.fill('WHITE')
city.render(screen)
current_text = city.enemies[city.current_enemy]
window.show(screen, current_text.get_text())
print(current_text.goods)
all_sprites.draw(screen)
pygame.display.update()
pygame.display.flip()`
Never run game loops recursively. Use the one application loop to draw the scene depending on states. You should never jump to another application loop in an event. The event should only change a state that is used to draw the scene. e.g.:
game_state = 'A'
run = True
while run:
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
if event.type == pygame.KEYDOWN:
game_state = 'B'
screen.fill('WHITE')
if game_state == 'A':
# draw scene A
elif game_state == 'B':
# draw scene B
pygame.display.flip()
I want the screen to change to all black after the enter button is pressed.
I was trying to have the screen clear here, when the enter key gets pressed:
def newScreen(self):
for event in pygame.event.get():
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_RETURN:
pygame.win.fill(self,(0,0,0))
for event in pygame.event.get():
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_RETURN:
win.fill((0,0,0))
Even this will not work if you have a bigger code that is blitting something else on the screen like a background in the while loop as it will again blit the background and black screen would be visible for a micro second thus you will need to define a variable(black_fill is my name) and set its value as False and if not black_fill: than only blit the other images and else: win.fill((0,0,0)).Also when enter is pressed( the way you tracked its clicking by events) just make black_fill as True.
win = pygame.display.set_mode((1000, 500))
black_fill = False
bg = pygame.image.load('any_bg_file')
while True:
for event in pygame.event.get():
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_RETURN:
black_fill = True
if not black_fill:
win.blit(bg, (0, 0))
else:
win.fill((0, 0, 0))
pygame.display.flip()
I'm trying to add a title screen to my game in pygame using a title_screen function but whenever I call it it doesn't actually load the title screen, what am I doing wrong?
This is my code for the title screen function:
#started
started = False
#declaring surface
window = pygame.display.set_mode((WIDTH,HEIGHT), 0, 32)
pygame.display.set_caption('Pong')
def title_screen(canvas):
canvas.fill(BLACK)
#NOT WORKING
and this is how I'm calling it + how I'm calling the rest of the code for my game
while not started:
title_screen(window)
pygame.display.update()
fps.tick(60)
init()
while True:
draw(window)
for event in pygame.event.get():
if event.type == KEYDOWN:
keydown(event)
elif event.type == KEYUP:
keyup(event)
elif event.type == QUIT:
pygame.quit()
sys.exit()
pygame.display.update()
fps.tick(60)
try to do pygame.init() before declaring window as an surface.
My collide_rect function is not working as I expect to be. The problem is when press the key 'r', it should be able to reset everything and continue the game. But when I actually press the key 'r', it does not change anything when I add in the pause statement. I want to have the game pause when two of the sprites I have(ball, obstacle) collide. After the user inputs the letter 'r', it should go back to running and reset position for both sprites. The error I am getting is when I press the key 'r', it does not change anything on the surface.
This is my while loop:
paused = False
def display_text(text):
font = pygame.freetype.Font('helvetica.ttc', 32)
text_attributed = font.render_to(gameDisplay, (300,300), text, black)
while not crashed:
time = pygame.time.get_ticks()
obstacle.change_x()
for event in pygame.event.get():
if event.type == pygame.QUIT:
crashed = True
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_UP:
ball.jump_true()
if event.key == pygame.K_SPACE:
ball.jump_true()
if event.key == pygame.K_r:
paused = not paused
if ball.collide == True:
gameDisplay.fill(white)
display_text('You Lost! type "R" to restart')
paused = True
if paused == True:
ball.reset_position()
obstacle.reset_position()
pygame.display.flip()
clock.tick(20)
else:
ball.jump()
ball.test_collision(obstacle)
gameDisplay.fill(white)
ball.update()
obstacle.update()
pygame.display.flip()
clock.tick(60)
pygame.quit()
sys.exit()
Don't overcomplicate things. You don't need multiple event loops. Use 1 main loop, 1 event loop and a state which indicates if the game is paused. e.g.:
paused = False
run = True
while run:
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_r
# Toggle pause
paused = not paused
if paused:
# "pause" mode
# [...]
else
# "run" mode
# [...]
# update display etc.
# [...]
I want to create a really simple application that starts a song while you press the SPACE bar, but when I start the application and press the space bar, I just hear a "pop" sound, and nothing starts. No music.
Here is the code:
import pygame
from pygame.locals import *
pygame.init()
backimage = pygame.display.set_mode((395, 702), RESIZABLE)
fond = pygame.image.load("background.jpg").convert()
backimage.blit(fond, (0,0))
pygame.display.flip()
pygame.mixer.pre_init(42000,-16,1,2048)
pygame.mixer.init()
musik = pygame.mixer.Sound(b'musik.wav')
continuer = 1
while continuer == 1:
for event in pygame.event.get():
if event.type == QUIT:
continuer = 0
for event in pygame.event.get():
if event.type == KEYDOWN and event.key == K_SPACE:
musik.play()
Ok, thank you so much guys ! It works perfectly now.
Here is the final code if someone has the same problem as me:
import pygame
from pygame.locals import *
pygame.init()
backimage = pygame.display.set_mode((395, 702), RESIZABLE)
fond = pygame.image.load("background.jpg").convert()
backimage.blit(fond, (0,0))
pygame.display.flip()
pygame.mixer.init()
pygame.mixer.music.load(b'musik.mp3')
pygame.event.clear()
while True:
event = pygame.event.wait()
if event.type == QUIT:
pygame.quit()
sys.exit()
elif event.type == KEYDOWN and event.key == K_SPACE:
pygame.mixer.music.play()
elif event.type == KEYUP and event.key == K_SPACE:
pygame.mixer.music.stop()
I don't know why the code doesn't work, but I know it does work if you use a mp3 file. try this:
import pygame
from pygame.locals import *
pygame.init()
backimage = pygame.display.set_mode((395, 702), RESIZABLE)
fond = pygame.image.load("background.jpg").convert()
backimage.blit(fond, (0,0))
pygame.display.flip()
pygame.mixer.init()
pygame.mixer.music.load(b'musik.mp3')
continuer = 1
while continuer == 1:
for event in pygame.event.get():
if event.type == QUIT:
continuer = 0
for event in pygame.event.get():
if event.type == KEYDOWN and event.key == K_SPACE:
pygame.mixer.music.play()
If you want to use your .wav file you can find .wav to .mp3 online
I think that you misunderstood the use for pygame.event. You should try with pygame.event.wait() :
pygame.event.clear()
while True:
# wait until new event happens - blocking instruction
event = pygame.event.wait()
if event.type == QUIT:
pygame.quit()
sys.exit()
elif event.type == KEYDOWN and event.key = K_SPACE:
musik.play()
