It looks like in pygame, screen command, like in screen.fill() is not in pygame. How do I set the background color?
Here is the code if needed:
pygame.display.set_mode([800, 600])
run = True
while run:
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
screen.fill((0, 0, 0))
pygame.display.update()
screen is not a built-in variable. It seems that in your case screen should be the pygame.Surface object associated with the display. This pygame.Surface is returned when the Pygame window is created with pygame.display.set_mode():
screen = pygame.display.set_mode([800, 600])
The other option is to get the display Surface with pygame.display.get_surface()
screen = pygame.display.get_surface()
screen.fill((0, 0, 0))

I'm currently trying to follow the Introduction to Pygame tutorial and I'm stuck on one step where the speaker makes the surface. His surface is bright red while my surface isn't visible at all.
Here's the code:
import pygame
from sys import exit
pygame.init()
screen = pygame.display.set_mode((800, 400))
pygame.display.set_caption('Runner')
clock = pygame.time.Clock()
test_surface = pygame.Surface((100, 200))
test_surface.fill('Red')
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
exit()
screen.blit(test_surface, (0, 0))
pygame.display.update()
clock.tick(60)
I've already tried starting from the very beginning, my code and the steps I make are identical to his. I've also tried deleting python and pygame. I've installed Python version that the speaker has (3.9), but nothing helps.
It is a matter of indentation. You have draw the scene and update the display in the application loop:
import pygame
from sys import exit
pygame.init()
screen = pygame.display.set_mode((800, 400))
pygame.display.set_caption('Runner')
clock = pygame.time.Clock()
test_surface = pygame.Surface((100, 200))
test_surface.fill('Red')
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
exit()
# INDENTATION
#<------|
screen.blit(test_surface, (0, 0))
pygame.display.update()
clock.tick(60)
(i followed a yt tut so idk) my code: idk if i put code in wrong place
import pygame
white = (255,255,255)
black = (0,0,0)
orange = (255,165,0)
player_sprite = pygame.image.load("will smith.png") .convert_alpha
pygame.init()
display = pygame.display.set_mode((850,850))
pygame.display.set_caption('Conners Game')
exit = False
while not exit:
for event in pygame.event.get():
if event.type == pygame.QUIT:
exit = True
print(event)
display.fill(white)
pygame.display.update()
pygame.quit()
quit()
not really sure why it does this, im new to python so idk
There are multiple things that needs to fixed. First of all to you actually need to blit the image on the screen.
while not exit:
for event in pygame.event.get():
#...[block of code]
display.fill(white)
display.blit(player_sprite, (100,100)) # BLIT IMAGE TO SCREEN
.convert_alpha() is a method and you need to call it after you initialize pygame and set the video mode.
You can read more about convert_alpha() here
pygame.init()
display = pygame.display.set_mode((850,850))
pygame.display.set_caption('Conners Game')
#converting it after init and setting game mode
player_sprite = pygame.image.load("will smith.png").convert_alpha()
Here's the final working code
import pygame
white = (255,255,255)
black = (0,0,0)
orange = (255,165,0)
pygame.init()
display = pygame.display.set_mode((850,850))
pygame.display.set_caption('Conners Game')
player_sprite = pygame.image.load("will smith.png").convert_alpha()
exit = False
while not exit:
for event in pygame.event.get():
if event.type == pygame.QUIT:
exit = True
# print(event)
display.fill(white)
display.blit(player_sprite, (100,100))
pygame.display.update()
pygame.quit()
quit()
You have to blit the image in the application loop, after clearing the display and before updating the display:
display.blit(player_sprite, (100, 100))
convert_alpha is function. You missed the parentheses
player_sprite = pygame.image.load("will smith.png").convert_alpha
player_sprite = pygame.image.load("will smith.png").convert_alpha()
Also, you cannot call a pygame function before you initialize pygame. pygame.init() should be the very first pygame function called.
Complete example:
import pygame
white = (255,255,255)
black = (0,0,0)
orange = (255,165,0)
pygame.init()
display = pygame.display.set_mode((850,850))
pygame.display.set_caption('Conners Game')
player_sprite = pygame.image.load("will smith.png").convert_alpha()
exit = False
while not exit:
for event in pygame.event.get():
if event.type == pygame.QUIT:
exit = True
print(event)
display.fill(white)
display.blit(player_sprite, (100, 100))
pygame.display.update()
pygame.quit()
quit()
The typical PyGame application loop has to:
limit the frames per second to limit CPU usage with pygame.time.Clock.tick
handle the events by calling either pygame.event.pump() or pygame.event.get().
update the game states and positions of objects dependent on the input events and time (respectively frames)
clear the entire display or draw the background
draw the entire scene (blit all the objects)
update the display by calling either pygame.display.update() or pygame.display.flip()
Whenever I try to include "screen.fill(insert value here)" to my pygame code, the window instantly crashes. I can comment it out and my code works just fine. I'm really not sure why.
I've tried moving the line around, using other people's code in part - no luck.
import pygame
pygame.init()
win = pygame.display.set_mode((1000, 800))
pygame.display.set_caption("Tetris")
img=pygame.image.load("C:\\Users\\Charlotte\\Desktop\\tetris_grid.png")
win.blit(img,(450, 150))
running = True
while running:
screen.fill(0, 0, 0)
pygame.display.update()
pygame.time.delay(100)
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
pygame.quit()
When I run the code with that line in it, the window opens and then it instantly closes.
If you are trying to fill the screen with black, the color must be passed as a tuple:
win.fill((0, 0, 0))
Also, you never assign screen, maybe you intended to use win?
The doc for Surface.fill.
The color parameter to fill() has to be either a single grayscale value or a tuple of 3 RGB or 4 RGBA components. So it has to be either:
win.fill(0)
or
win.fill((0, 0, 0))
Further you've to blit() the image in the main loop. To continuously draw the scene in the main application loop, you've to:
handle the events
clear the window
draw the scene (blit the image)
update the display
Furthermore I recommend to use tick() of pygame.time.Clock rather than pygame.time.delay() tpo control the frames per second.
import pygame
pygame.init()
win = pygame.display.set_mode((1000, 800))
pygame.display.set_caption("Tetris")
clock = pygame.time.Clock()
img=pygame.image.load("C:\\Users\\Charlotte\\Desktop\\tetris_grid.png")
running = True
while running:
clock.tick(60)
# handle the events
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
# clear the display
win.fill(0)
# draw the scene
win.blit(img,(450, 150))
# update the display
pygame.display.update()
pygame.quit()
I've just started working with pygame and all the sample (getting started) code I have run, gives me a blank screen. Including the space invaders example which play the sound but shows only the grey blank screen as shown below.
grey blank screen
I am getting no errors in my terminal, I have tried with both python3 and python2.7. I have also tried with many different scripts but still I am getting the grey blank screen. Below is an example script I have tried to run. Any help would be great, thanks.
import pygame
from pygame.locals import *
yellow = (255,255,0) # RGB color tuple
# initialize screen
pygame.init()
screen = pygame.display.set_mode((350, 250))
pygame.display.set_caption('Basic Pygame program')
# fill background
background = pygame.Surface(screen.get_size())
background = background.convert()
background.fill(yellow)
# display some text
font = pygame.font.Font(None, 36)
text = font.render("Hello from Monty PyGame", 1, (10, 10, 10))
textpos = text.get_rect()
textpos.centerx = background.get_rect().centerx
background.blit(text, textpos)
# blit everything to the screen
screen.blit(background, (0, 0))
pygame.display.flip()
# event loop
while True:
for event in pygame.event.get():
if event.type == QUIT:
raise SystemExit
screen.blit(background, (0, 0))
pygame.display.flip()
It's a matter of Indentation. You have to draw the background and update the display in the application loop rather than the event loop:
while True:
for event in pygame.event.get():
if event.type == QUIT:
raise SystemExit
# INDENTATION
#<--|
screen.blit(background, (0, 0))
pygame.display.flip()
My code runs with no errors, but the background image does not display and neither does the caption at the top of the window. I have checked that my script is importing the correct pygame module, and tried different images. I have Python 3.6.2 on a Mac.
import pygame
pygame.init()
gameDisplay = pygame.display.set_mode((400, 433))
pygame.display.set_caption('Pac Man')
clock = pygame.time.Clock()
background = pygame.image.load('/Users/MyMacbook/Desktop/pac-man/background.png')
gameDisplay.blit(background, (100, 0))
run = True
while run:
gameDisplay.blit(background, (0, 0))
pygame.display.update()
pygame.quit()
quit()
Yeah it appears that #skrx is correct, there's something blocking by not clearing the event buffer. This code works for me:
import pygame
pygame.init()
gameDisplay = pygame.display.set_mode((400, 433))
pygame.display.set_caption('Pac Man')
clock = pygame.time.Clock()
background = pygame.image.load('/Path/To/Background.png')
gameDisplay.blit(background, (100, 0))
run = True
while run:
for e in pygame.event.get():
if e.type == pygame.QUIT:
run = False
gameDisplay.blit(background, (0, 0))
pygame.display.update()
pygame.quit()
quit()
