I am trying to get user keyboard input using pygame. However, the problem is that after I run my code on IDLE, the keyboard input is never read by the program, and whatever I type is shown on the shell. Same issue if I run my code on PyCharm. Any idea? Below is my code:
pygame.init()
screen = pygame.display.set_mode((800, 600))
running = True
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
elif event.type == KEYDOWN and event.key == pygame.K_w:
print("Yup!")
pygame.display.flip()
I'm having the exact same issue, also on a Mac using Pycharm and python 3.6. I'm printing the events and only MouseMotion events are recorded, rather than KeyDown.
Edit: apparently it's a known issue: Window does not get focus on OS X with Python 3
This is my code, and it also should work:
while not crashed:
for event in pygame.event.get():
print(event)
if event.type == pygame.QUIT:
crashed = True
# get current list
pressed = pygame.key.get_pressed()
if pressed[pygame.K_UP]:
print("UP")
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_1:
print('this DOES work! :)')
elif event.key == pygame.K_LEFT:
x_change = -5
elif event.key == pygame.K_RIGHT:
x_change = 5
elif pressed[pygame.K_UP]:
print("UP")
if event.type == pygame.KEYUP:
if event.key == pygame.K_LEFT or event.key == pygame.K_RIGHT:
x_change = 0
pygame.display.flip()
x += x_change
gameDisplay.fill(black)
ship(x, y)
pygame.display.update()
clock.tick(60)
This code works perfectly for me
import pygame
pygame.init()
windowSize = width,height = 800,600
screen = pygame.display.set_mode(windowSize)
running = True
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
quit()
elif event.type == pygame.KEYDOWN:
if event.key == pygame.K_w:
print("Yup!")
pygame.display.flip()

color = (128,255,0)
pygame.draw.rect(bg, color, pygame.Rect(x,y,50,50))
pygame.display.flip()
I think the error was due to the function, but IDK because of a pygame import error.
Please help me make the controls thing into a loop.
I've recently started Python and I'm learning from a book but I think the book either uses an old version or it's not made very well. Using some code I tried to create a simple moving character.
#!/usr/bin/python3
import pygame
from pygame.locals import *
pygame.init()
running = True
gamewindow=pygame.display.set_mode((800, 600))
pygame.display.set_caption("Game")
black=(0, 0, 0)
white=(255, 255, 255)
img=pygame.image.load("/home/leo/Downloads/pixel.png")
def sprite(x,y):
gamewindow.blit(img, (x,y))
x=(800*0.2)
y=(600*0.735)
xchange=0
imgspeed=0
while running:
for event in pygame.event.get():
if event.type==QUIT:
running = False
if event.type == pygame.KEYDOWN:
if event.type == pygame.K_LEFT:
xchange=-5
elif event.type == pygame.K_RIGHT:
xchange=5
if event.type==pygame.KEYUP:
if event.type==pygame.K_LEFT or event.key==pygame.K_RIGHT:
xchange=0
x= x + xchange
gamewindow.fill(white)
sprite(x,y)
pygame.display.update()
pygame.quit()
Using this code, the character doesn't move and I think it may be due to the wrong functions in this section:
while running:
for event in pygame.event.get():
if event.type==QUIT:
running = False
if event.type == pygame.KEYDOWN:
if event.type == pygame.K_LEFT:
xchange=-5
elif event.type == pygame.K_RIGHT:
xchange=5
if event.type==pygame.KEYUP:
if event.type==pygame.K_LEFT or event.key==pygame.K_RIGHT:
xchange=0
x= x + xchange
Is the book completely wrong or is there just a few small things I have to change. Thank you!
You check type of event instead of the event key. For example you should use event.key == pygame.K_LEFT instead of event.type == pygame.K_LEFT etc.
How do you think event.type can be equal pygame.K_LEFT and pygame.KEYDOWN in the same time?
See How to use pygame.KEYDOWN for the correct example.
I started watching a youtube video series on learning pygame by sentdex.
I have been following all his steps and i got to the point where i had a car(the image) and it was on a white screen. But, when i put in the functions to be able to move the car. Next time i ran it I could not see my car. I noticed that I could see it for a split second when i closed the screen.I have tried searching this question every way that i could think of. It is probably a small stupid mistake on my part. Thank you in advance

Your indentation is messed up. Everything from for event in pygame.event.get(): to clock.tick(60) should be indented to show that it fits inside the while not crashed: loop. Also, crashed = True should be indented to show that it is inside the if event.type == pygame.QUIT: statement. In addition, the pygame.KEYDOWN and pygame.KEYUP comparisons should be inside your for event in pygame.event.get(): loop. Finally, you can improve speed by changing some of the ifs to elifs. This is the corrected version of the last section of your code:
while not crashed:
for event in pygame.event.get():
if event.type == pygame.QUIT:
crashed = True
elif event.type == pygame.KEYDOWN:
if event.key == pygame.K_LEFT:
x_change = -5
elif event.key == pygame.K_RIGHT:
x_change = 5
elif event.type == pygame.KEYUP:
if event.key == pygame.K_LEFT or event.key == pygame.K_RIGHT:
x_change = 0
x += x_change
gameDisplay.fill(white)
car(x, y)
pygame.display.update()
clock.tick(60)
pygame.quit()
quit()
I am trying to make a fun program with a guy who opens his mouth whenever a press space. The problem is he only opens it for .1 seconds and then it closes again. I want to make it so that the mouth is open whenever i hold space.
Code:
import pygame
pygame.init()
display_width = 800
display_height = 600
gameDisplay = pygame.display.set_mode((display_width,display_height))
pygame.display.set_caption("Open The Mouth")
clock = pygame.time.Clock()
faceImg = pygame.image.load("face_shut.png")
faceOpenImg = pygame.image.load("face_open.png")
def face(x,y):
gameDisplay.blit(faceImg,(face_x,face_y))
def faceOpen(x,y):
gameDisplay.blit(faceOpenImg,(faceOpen_x,faceOpen_y))
faceOpen_x = (1)
faceOpen_y = (1)
face_x = (1)
face_y = (1)
programRunning = True
while programRunning:
for event in pygame.event.get():
if event.type == pygame.QUIT:
programRunning = False
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_SPACE:
faceOpen(faceOpen_x,faceOpen_y)
pygame.display.update()
if event.type == pygame.KEYUP:
if event.key == pygame.K_SPACE:
face(face_x,face_y)
pygame.display.update()
face(face_x,face_y)
pygame.display.update()
clock.tick(60)
pygame.quit()
quit()
The issue appears to be here:
while programRunning:
for event in pygame.event.get():
if event.type == pygame.QUIT:
programRunning = False
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_SPACE:
faceOpen(faceOpen_x,faceOpen_y)
pygame.display.update()
if event.type == pygame.KEYUP:
if event.key == pygame.K_SPACE:
face(face_x,face_y)
pygame.display.update()
# Here, always drawn closed at the end of the while
face(face_x,face_y)
pygame.display.update()
clock.tick(60)
Regardless of what's being set in the while, you are redrawing the face as closed at the end.
How about this instead:
# Drawn before the loop starts
face(face_x,face_y)
pygame.display.update()
while programRunning:
for event in pygame.event.get():
event_occurred = True
if event.type == pygame.QUIT:
programRunning = False
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_SPACE:
faceOpen(faceOpen_x,faceOpen_y)
pygame.display.update()
if event.type == pygame.KEYUP:
if event.key == pygame.K_SPACE:
face(face_x,face_y)
pygame.display.update()
clock.tick(60)
I am kinda stuck with a supposed to be simple code to check if the user has pressed "w" or "s".
Below you can see my code:
import pygame
pygame.init()
while True:
for event in pygame.event.get():
if event.type == pygame.KEYDOWN and event.key == pygame.K_w:
print('Forward')
elif event.type == pygame.KEYDOWN and event.key == pygame.K_s:
print('Backward')
Am I forgetting something here?
Thanks!
A window needs to be created to receive key presses, the following works.
import pygame
import sys
pygame.init()
pygame.display.set_mode((100, 100))
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
sys.exit()
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_w:
print('Forward')
elif event.key == pygame.K_s:
print('Backward')
This is what seems to me the most simple and understandable way to do it:
import pygame
pygame.init()
pygame.display.set_mode((300, 300))
running = True
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
pygame.quit()
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_w:
print('Forward')
elif event.key == pygame.K_s:
print('Backward')
Instead of using the sys.exit() method I prefer to just use pygame.quit()
it is no good to ask the gamer to keep hitting w to get the response. If you want to read the "pressed" state. You could consider the followings:
from pygame import *
import time
flag = False # The flag is essential.
DONE = False
screen = display.set_mode((500,500)) # 1180, 216
count=0
while not DONE:
event.pump() # process event queue
keys = key.get_pressed() # It gets the states of all keyboard keys.
#print("%d"%count,keys)
count+=1
if keys[ord('w')]: # And if the key is K_DOWN:
print("%d w down"%count)
if keys[ord('s')]: # And if the key is K_DOWN:
print("%d s down"%count)
time.sleep(0.1)
Try this:
import pygame
pygame.init()
key = pygame.key.get_pressed()
while True:
for event in pygame.event.get():
if event.type == KEYDOWN and event.key == pygame.K_w:
print('Forward')
elif event.type == KEYDOWN and event.key == pygame.K_s:
print('Backward')
Sample code to understand how key press events work.
import pygame
from pygame.locals import *
def main():
pygame.init()
pygame.display.set_caption("Move Box With Arrow Keys")
wndsize = (320, 240)
display = pygame.display.set_mode(wndsize)
x = 5
y = 5
black = (0, 0, 0)
white = (255, 255, 255)
rectpos = (x, y)
rectdim = (50, 50)
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
quit()
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_RIGHT:
x += 5
print("K_RIGHT")
if event.key == pygame.K_LEFT:
x -= 5
print("K_LEFT")
if event.key == pygame.K_UP:
y -= 5
print("K_UP")
if event.key == pygame.K_DOWN:
y += 5
print("K_DOWN")
# Don't allow coords below 0
if 0 > x:
x = 5
if 0 > y:
y = 5
# Don't allow overflow
if x + rectdim[0] > wndsize[0]:
x = wndsize[0] - rectdim[0] - 5
if y + rectdim[1] > wndsize[1]:
y = wndsize[1] - rectdim[1] - 5
rectpos = (x, y)
display.fill(white)
rect = pygame.draw.rect(display, black, ((rectpos), (rectdim)))
pygame.display.update()
main()
This might work:
from pygame import *
init()
if key.get_pressed()[K_w] == True:
print('Forwards')
if key.get_pressed()[K_s] == True:
print('Backwards')`
