How to get keyboard input in pygame?

What all things happens inside pygame when I press a key? When to use pygame.event==KEYDOWN
(1 answer)
Closed 2 years ago.
I have installed vs code and added pygame snippets to use pygame library. My big problem is, every time I try to use any key option of pygame, like pygame.KEYDOWN or pygame.QUIT it tells me that QUIT is not a function of pygame. Can someone help me?
Everything else seems to work, like display or surface
even pygame.key.get_pressed() don’t make problems.
import pygame, random, sys
from pygame.locals import *
from pygame.key import *
def set_Background():
screen = pygame.display.set_mode((500,500))
surface = pygame.image.load('Background.png')
surface = pygame.transform.scale(surface, (500, 500))
screen.blit(surface, (0,0))
pygame.display.update()
return screen
def set_Enemy():
enemy = pygame.image.load('Enemy.png')
enemy = pygame.transform.scale(enemy, (50, 50))
return enemy
def set_Player():
player = pygame.image.load('Player.png')
player = pygame.transform.scale(player, (70, 70))
return player
RUNNING = True
while RUNNING:
background = set_Background()
enemy = set_Enemy()
player = set_Player()
enemy_rect = enemy.get_rect()
player_rect = player.get_rect()
e_x = random.randint(10,450)
e_y = random.randint(10,450)
background.blit(enemy, (e_x, e_y))
pygame.display.update()
for event in pygame.event.get():
key = pygame.key.get_pressed()
if event.type == key[pygame.K_ESCAPE]:
#module pygame has no K_ESCAPE member
sys.exit()
if event.type == pygame.QUIT:
#says module pygame has no QUIT member
sys.exit()
pygame.key.get_pressed() shouldn't be in the event loop, but in the main while loop. In the event loop you need to check if the event type is pygame.QUIT and then set the running flag to False.
Here's a fixed version:
import pygame
pygame.init()
screen = pygame.display.set_mode((500,500))
clock = pygame.time.Clock()
running = True # Uppercase names are for constants not variables.
while running:
# The event loop.
for event in pygame.event.get():
# If a pygame.QUIT event is in the queue.
if event.type == pygame.QUIT:
running = False
# To check if it was a `KEYDOWN` event.
elif event.type == pygame.KEYDOWN:
# If the escape key was pressed.
if event.key == pygame.K_ESCAPE:
running = False
# Use pygame.key.get_pressed to see if a key is held down.
# This should not be in the event loop.
key = pygame.key.get_pressed()
if key[pygame.K_UP]:
print('up arrow pressed')
screen.fill((30, 30, 30))
pygame.display.flip()
clock.tick(60)
Add from pygame.locals import * at the top of your code.
You are mixing two types of key presses in one go. You should instead either
for event in pygame.event.get():
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_SOMEKEY:
do_something()
or
keys = pygame.key.get_pressed()
if keys[pygame.K_somekey]:
do_something()
so the code above with the pygame.key.get_pressed() should not be in the event loop

How to get keyboard input in pygame?

Closed last month.
I'm trying to create a game in pygame where the character moves while animating, I tired using sprites but got the same results, however I did notice that pygame wasn't detecting that I pressed the right arrow key, I tried to get it to work but alas.
here's my code
:
import pygame
from sys import exit
def player_animation():
global player_current_sprite, player_frames, player_image
player_current_sprite += 0.01
player_image = player_frames[int(player_current_sprite)]
if player_current_sprite >= 1.3:
player_current_sprite = 0.7
pygame.display.set_caption('pausing has consequences')
pygame.init()
screen = pygame.display.set_mode((1000, 700))
clock = pygame.time.Clock()
player_frame_1 = pygame.image.load('graphics/player_frame_1.png')
player_frame_2 = pygame.image.load('graphics/player_frame_2.png')
player_current_sprite = 0
player_frames = [player_frame_1, player_frame_2]
player_image = player_frames[player_current_sprite]
player_rect = player_image.get_rect(center=(450, 250))
move = False
background_surface = pygame.image.load('graphics/background.png')
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
exit()
if event.type == pygame.KEYDOWN:
move = True
if event.type == pygame.K_RIGHT and move == True:
player_rect.x += 10
if event.type == pygame.KEYUP:
move = False
screen.blit(background_surface, (0, 0))
player_animation()
screen.blit(player_image, player_rect)
pygame.display.flip()
clock.tick(60)
The x value does not change when I pressed the button, I did notice that pygame did not detect my button press

In this I want the program to close when they hit the quit button but if I enable my Check_Key_Press() function, the Close() function does not work however If I comment out the Check_Key_Press() function then it works again.
import pygame
pygame.init()
width, height = 500,500
win = pygame.display.set_mode((width, height))
pygame.display.set_caption("Tic Tac Toe(GUI)")
clock = pygame.time.Clock()
white = (255,255,255)
red = (255,0,0)
green = (0,255,0)
blue = (0,0,255)
Tile_dime = 59
Diff = (Tile_dime+1)/2
board_det = [['-',(width/2-3*Diff,height/2-3*Diff)],['-',(width/2-Diff,height/2-3*Diff)],['-',(width/2+Diff,height/2-3*Diff)],
['-',(width/2-3*Diff,height/2-Diff)],['-',(width/2-Diff,height/2-Diff)],['-',(width/2+Diff,height/2-Diff)],

def draw_board():
for i in range(len(board_det)):
pygame.draw.rect(win, white, [board_det[i][1], (Tile_dime, Tile_dime)])
def Close():
global run
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
def Check_Key_Press():
for event in pygame.event.get():
if event.type == pygame.KEYDOWN:
pass
if event.key == pygame.K_LEFT:
pass
run = True
while run:
clock.tick(60)
draw_board()
Check_Key_Press()
Close()
pygame.display.update()
pygame.event.get() get all the messages and remove them from the queue. If pygame.event.get () is called in multiple event loops, only one loop receives the events, but never all loops receive all events. As a result, some events appear to be missed.
Get the events once and use them in multiple loops or pass the list or events to functions and methods where they are handled:
def Close(event_list):
global run
for event in event_list:
if event.type == pygame.QUIT:
run = False
def Check_Key_Press(event_list):
for event in event_list:
if event.type == pygame.KEYDOWN:
pass
if event.key == pygame.K_LEFT:
pass
run = True
while run:
clock.tick(60)
event_list = pygame.event.get()
draw_board()
Check_Key_Press(event_list)
Close(event_list)
pygame.display.update()
I am making a new game in pygame and the blit function just is not working for me, it should be simple but I just don't know what's wrong.
import pygame
import sys
pygame.init()
clock = pygame.time.Clock()
game = True
WIDTH = 160
HEIGHT = 144
screen = pygame.display.set_mode((WIDTH, HEIGHT), pygame.FULLSCREEN)
level = pygame.image.load('RBYG/Level.png')
def redrawGameWindow():
screen.blit(level, (0, 0))
while game:
screen.blit(level,(0, 0))
for event in pygame.event.get():
print(event)
if event.type == pygame.QUIT:
sys.exit()
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_ESCAPE:
sys.exit()
redrawGameWindow()
clock.tick(60)
You're missing pygame.display.flip(), you have to do that after you blit or nothing will happen. Your redrawGameWindow() function should flip the display. Also, you're calling screen.blit(level, (0, 0)) twice in your main loop, which may be unnecessary; try just keeping one of them (just make sure to flip() after).
Whenever I try to run my program it freezes up and crashes. I'm not a master pygame coder, but I'm almost sure its something to do with my main loop. It's supposed to allow the user to move left and right using arrow keys. I've tried adding a clock and changing the size of the screen but that didn't work. Here is the code:
import pygame
import sys
import random
import time
pygame.init()
screen = pygame.display.set_mode((500,500))
events = pygame.event.get()
clock = pygame.time.Clock()
x = 50
y = 50
game_over = False
while not game_over:
for event in events:
if event.type != pygame.QUIT:
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_RIGHT:
x += 5
elif event.key == pygame.K_LEFT:
x -= 5
else:
sys.exit()
screen.fill((0,0,0))
pygame.draw.rect(screen, (255,255,255), (x,y,50,50))
clock.tick(30)
pygame.display.update()
The code needs to process the event queue continuously, otherwise your operating environment will consider your window to be non-responsive (locked up). Your code is almost there, except it only fetches the new events once, but this needs to be done every iteration of the main loop.
import pygame
import sys
pygame.init()
screen = pygame.display.set_mode((500,500))
clock = pygame.time.Clock()
x = 50
y = 50
game_over = False
while not game_over:
events = pygame.event.get() # <<-- HERE handle every time
for event in events:
if event.type != pygame.QUIT:
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_RIGHT:
x += 5
elif event.key == pygame.K_LEFT:
x -= 5
else:
sys.exit()
screen.fill((0,0,0))
pygame.draw.rect(screen, (255,255,255), (x,y,50,50))
clock.tick(30)
pygame.display.update()
You cant do foe event in events, as when you call pygame.events.get(), you are updating them, you are updating them once and looping over them every frame, you need to use for event in pygame.event.get(): so you are calling the function every frame and updating the events every frame
unless you were trying to do this?
events = pygame.event.get
...
for event in events():
which does the same as above

Closed 2 years ago.
this code is supposed to go to a different function which clears the screen when you hit z, and it does do that, but whenever I let go of z it switches back to the title function and redraws everything.
I'm trying to use it as a "hit this key to go to a new window" type thing and the screenfill is just a fill-in for now, so you can see why that's a problem. for the record I'm using python 3.6.
I've also already tried putting global start in the top of the title function, but then the z key does nothing. please and thanks!
