I am trying to move my sprite across the screen when the window starts.... It moves for a second than stops for a while than it starts back up again. its not giving me an error.... So im really not sure whats going on here.... anyway here is the code.... any info is needed!
thanks,
import pygame
from sys import exit
pygame.init()
screen = pygame.display.set_mode((800,400))
sky_surface = pygame.image.load("bg_desert.png")
snail_surface = pygame.image.load("snailWalk1.png")
snail_x_pos = 600
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
exit()
snail_x_pos -=1
screen.blit(sky_surface,(0,0))
screen.blit(snail_surface,(snail_x_pos,350))
pygame.display.update()
Your loop will only execute when there are events. When there are no events, you don't move. If you wiggle your mouse in front of the screen, for example, you'll see pretty continuous movement.
You need to use pygame.time.set_timer to force an event for you to update.
It looks like the final 4 lines you have written are designed to run on each cycle of the for loop, however they will only run when an event occurs, because they are indented a block too far.
Your new code should look like this:
import pygame
from sys import exit
pygame.init()
screen = pygame.display.set_mode((800,400))
sky_surface = pygame.image.load("bg_desert.png")
snail_surface = pygame.image.load("snailWalk1.png")
snail_x_pos = 600
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
exit()
snail_x_pos -=1
screen.blit(sky_surface,(0,0))
screen.blit(snail_surface,(snail_x_pos,350))
pygame.display.update()

I'm making a calculator in pygame but when I click the button, I want the number to stay on the screen but instead of staying on the screen, the number just appears when my mouse is clicked. When I release it, the numbers disappears. Does anyone know a solution for this?
My code:
import pygame
from sys import exit
pygame.init()
screen = pygame.display.set_mode((600,800))
pygame.display.set_caption("Calculator")
clock = pygame.time.Clock()
font1 = pygame.font.Font("c:/Users/oreni/OneDrive/Masaüstü/sprites/minecraft.ttf", 100)
one = 1
one_main = font1.render(str(one), False, "black")
one_main_r = one_main.get_rect(center = (75,100))
one_button = pygame.Surface((142.5,142.5))
one_button.fill("white")
one_button_r = one_button.get_rect(topleft = (0,160))
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
exit()
screen.fill("black")
screen.blit(one_button,one_button_r)
if event.type == pygame.MOUSEBUTTONDOWN:
if one_button_r.collidepoint(event.pos):
screen.blit(one_main,one_main_r)
pygame.display.update()
clock.tick(60)
The usual way is to redraw the scene in each frame. You need to draw the text in the application loop. Set a variable that indicates that the image should be drawn when the mouse is clicked, and draw the image according to that variable:
draw_r = False
run = True
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
if event.type == pygame.MOUSEBUTTONDOWN:
if one_button_r.collidepoint(event.pos):
draw_r = True
screen.fill("black")
screen.blit(one_button,one_button_r)
if draw_r:
screen.blit(one_main, one_main_r)
pygame.display.update()
clock.tick(60)
pygame.quit()
exit()
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()
I am making a game with pygame and I have a waiting music for the lobby. I want this to play until the game starts. It would play a beginning part and then loop the rest infinitely. I have gone back and forth on what I should use to make the game. At first I was using unity with FMOD. This is what it was like in FMOD and what I am aiming to do in python
well, you can set a countdown until the beginning part is completed and then it will start looping the middle part like this:
import pygame
from pygame import mixer
import sys
pygame.init()
screen = pygame.display.set_mode((400, 400))
clock = pygame.time.Clock()
songBeginningLength = 15
pygame.time.set_timer(pygame.USEREVENT, 1000)
mixer.music.load('BeginningPart.wav')
pygame.mixer.music.play(1) # loop 1
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
if event.type == pygame.USEREVENT:
songBeginningLength -= 1
if songBeginningLength == 0: # check if countdown is done
mixer.music.load('MiddlePart.wav')
pygame.mixer.music.play(-1, 0.0) # loop forever
clock.tick(60)
I'm new to PyGame (and python in general) and I am just trying to get a window to pop up. That's all I'm after for now. Here's my code:
import pygame
pygame.init()
win = pygame.display.set_mode((600, 600))
pygame.display.set_caption('First Game')
I am using Python 3.7.0 in Pycharm and PyGame 1.9.4.
Following Python's PyGame tutorial, your next step is to start a while loop to handle the game frames:
import pygame
pygame.init()
win = pygame.display.set_mode((600, 600))
pygame.display.set_caption('First Game')
clock = pygame.time.Clock() # Determine FPS (frames-per-second)
crashed = False
# Game loop
while not crashed:
for event in pygame.event.get():
if event.type == pygame.QUIT:
crashed = True
print(event)
pygame.display.update()
clock.tick(60)
Because you need to first put it inside a loop (so it refreshes whatever is inside it), that way it stays on until something alters the condition of that loop.
# Event loop (HERE YOU PUT IT).
while 1:
for event in pygame.event.get():
if event.type == QUIT:
return
screen.blit(background, (0, 0))
pygame.display.flip()
if __name__ == '__main__': main()
Using Python (and Pygame), I have been creating a short one-screen game and I code each part in a different window. In my Home Screen, when I blit the play button onto the screen, it doesn't appear. I am new to Python and Pygame. This is my code:
import pygame, sys
from pygame.locals import *
pygame.init()
screen = pygame.display.set_mode((1352,638))
pygame.display.set_caption("Termination: Part 1")
bg = True
playButton = pygame.image.load("Play Button.png")
mouse = pygame.mouse.get_pos()
def playButtonFunction():
if background == pygame.image.load("Home Screen.png"):
background.blit(playButton(533.5,278))
while True:
for event in pygame.event.get():
if event.type == QUIT:
pygame.quit()
sys.exit()
if event.type == KEYDOWN and event.key == K_SPACE:
bg = False
screen.blit(background,(0,0))
if bg:
background = pygame.image.load("Intro Screen.png")
else:
background = pygame.image.load("Home Screen.png")
playButtonFunction()
pygame.display.update()
As Frédéric Hamidi already said in a comment, the line
if background == pygame.image.load("Home Screen.png")
will not work as you probably expect.
You should probabkly pass a flag to that method or don't call that function at all when you don't want to show that playButton image.
Also, the line
background.blit(playButton(533.5,278))
will throw an exception, it should look like
background.blit(playButton, (533, 278))
So, change your code to
...
if bg:
background = pygame.image.load("Intro Screen.png")
else:
background = pygame.image.load("Home Screen.png")
screen.blit(background,(0,0))
if !bg:
background.blit(playButton, (533, 278))
...
Another issue that you load the images from disk every iteration of your game loop (with pygame.image.load). It's enough to load each image once.
I'm trying to run code from a tutorial I found online.
But when I run this code, my background image does not appear, even if it loaded correctly.
Why?
bif = "castle.jpg"
import pygame, sys, pygame.mixer
from pygame.locals import *
pygame.init()
screen = pygame.display.set_mode((1280,960),0, 32)
background = pygame.image.load(bif).convert()
pygame.display.set_caption("castlevania ultimate")
hit_sound = pygame.mixer.Sound("02.wav")
hit = False
if hit is True:
hit_sound.play()
sound = pygame.mixer.Sound("castlevania_1.wav")
sound.play()
while True:
for event in pygame.event.get():
if event.type == QUIT:
pygame.quit()
sys.exit()
screen.blit(background, (0,0))
pygame.display.update()
You never call pygame.display.update() in your while loop.
Python is indentation sensitive, so the loop should look like this:
while True:
for event in pygame.event.get():
if event.type == QUIT:
pygame.quit()
sys.exit()
screen.blit(background, (0,0))
pygame.display.update()
Note that pygame.display.update() is now inside the while loop.
