I can not get the controls to work, I try to press escape to open a menu I made but it will not open and I do not know if I am checking for events correctly, is there a way I am SUPPOSED to do it?
I tried using the functions for checking for different keys and I went to the spread-sheet that displays all the event names so you can map them at pygame.org but it will not open when I use the escape or also known as:
elif event.type == pygame.K_ESCAPE:
Frame.blit('Textures/GUI/loom.png', (0,0))
Heres the full code:
import pygame
#Textures/Blocks/loom_side.png
pygame.init()
Screen = "None"
DB = 0
Width = 800
Height = 600
Frame = pygame.display.set_mode((Width,Height))
pygame.display.set_caption("HypoPixel")
FPS = pygame.time.Clock()
def Raycast(TTR, RayXPos, RayYPos, RaySizeX, RaySizeY):
RaycastThis = pygame.image.load(TTR)
RaycastThis = pygame.transform.scale(RaycastThis,(RaySizeX,RaySizeY))
Frame.blit(RaycastThis, (RayXPos, RayYPos))
Loop = True
Raycast('Textures/Screens/Skybox/Earth.png',0,0,800,600)
while Loop == True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
exit()
elif event.type == pygame.K_ESCAPE:
Frame.blit('Textures/GUI/loom.png', (0,0))
pygame.display.update()
FPS.tick(60)
I expected to get the loom GUI that I made. Once I tried to press escape, nothing happened.
pygame.K_ESCAPE is not event type (see pygame.event), but it is a pygame.key.
First check if a key was pressed by comparing the event type to pygame.KEYDOWN:
event.type == pygame.KEYDOWN
Then check if the event.key, which cause the event, is the pygame.K_ESCAPE key:
event.key == pygame.K_ESCAPE
Furthermore, the parameter to Surface.blit() has to be a Surface object rather than a filename.
first load the image to a Surface, by pygame.image.load(), then blit the Surface:
sprite = pygame.image.load('Textures/GUI/loom.png')
Frame.blit(sprite, (0,0))
Of course the your Raycast function can be called to do so:
Raycast('Textures/GUI/loom.png',0,0,800,600)
Your code should look somehow like this:
while Loop == True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
exit()
elif event.type == pygame.KEYDOWN and event.key == pygame.K_ESCAPE:
Raycast('Textures/GUI/loom.png',0,0,800,600)

why doesn't my window close when I press the escape key:
import pygame
pygame.display.init()
pygame.display.set_mode(size=(500, 500))
pygame.display.set_caption("hi")
x = 1
while True:
if pygame.key.get_mods() & pygame.K_ESCAPE:
x = 2
if x == 2:
pygame.quit()
You need an event-loop in your while-loop like so:
import pygame
pygame.display.init()
pygame.display.set_mode(size=(500, 500))
pygame.display.set_caption("hi")
x = 1
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT: # uses the small 'x' on the top right to close the window
pygame.quit()
if event.type == pygame.KEYDOWN: # processes all the Keydown events
if event.key == pygame.K_ESCAPE: # processes the Escape event (K_A would process the event that the key 'A' is hit
x = 2
if x == 2:
pygame.quit()
pygame.display.update()
I also added pygame.display.update(), which should normally be in your code.
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'm using pygame and pyautogui to move the mouse around the screen in python 2.7. My code looks like:
import pyautogui
import pygame
pygame.init()
pygame.display.set_mode()
loop = True
while loop:
for event in pygame.event.get():
if event.type == pygame.quit:
pygame.quit()
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_a:
pyautogui.moveRel(-50,0)
My code moves the mouse to the left when I press "a" but I have to repeatedly press the button when I want to move the mouse across the screen. Is there a way to be able to press and hold a and move the mouse across the screen? I've looked at other tutorials on this topic but they seem very project specific.
Basically, what you want to do is set a variable indicating whether the key is down on keydown and update it once key is up.
Here, I updated your code to do just that as it might be easier to understand.
import pyautogui
import pygame
loop = True
a_key_down = False # Added variable
while loop:
for event in pygame.event.get():
if event.type == pygame.quit:
pygame.quit()
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_a:
a_key_down = True # Replaced keydown code with this
if event.type == pygame.KEYUP: # Added keyup
if event.key == pygame.K_a:
a_key_down = False
if a_key_down: # Added to check if key is down
pyautogui.moveRel(-50,0)
I am using a function to wait until a controller is present, but i ran into a problem. I wanted the function to stop when I press a key. Usually these events are handled just fine, but in this part it works terrible. The event seems to be added to the event queue very late or sometimes not at all. My guess is that it is because of the uninitialisation and reinitialisation of pygame.joystick. I just don't know how to solve it. I used this program to create the error:
import pygame, sys
from pygame.locals import *
pygame.init()
SCREEN = pygame.display.set_mode((500,500))
ChangeRun = False
pygame.joystick.init()
if pygame.joystick.get_count() == 0:
while pygame.joystick.get_count() == 0:
for event in pygame.event.get():
if event.type == QUIT:
pygame.quit()
sys.exit()
elif event.type in [KEYUP, KEYDOWN]:
if event.key == K_ESCAPE:
ChangeRun = True
if ChangeRun == True:
break
pygame.joystick.quit()
pygame.joystick.init()
pygame.quit()
sys.exit()
I wanted to use the escape key to end the program, but only after a lot of pressing it works. The same happens with the QUIT event. When printing the events I found that most of the time no event was found.
I use windows 8.1 and python 3.4 and pygame 1.9.2
I have no joystick so I can't test it but normally I would do this similar to mouse and I wouldn't wait for controller:
import pygame
from pygame.locals import *
pygame.init()
pygame.joystick.init()
screen = pygame.display.set_mode((500,500))
running = True
while running:
for event in pygame.event.get():
if event.type == QUIT:
running = False
elif event.type == KEYDOWN:
if event.key == K_ESCAPE:
running = False
elif event.type == JOYBUTTONDOWN:
print 'joy:', event.joy, 'button:', event.button
# the end
pygame.joystick.quit()
pygame.quit()
I'm using pygame to draw a line:
import pygame
from pygame.locals import*
import sys
pygame.init()
screen = pygame.display.set_mode((600,500))
pygame.display.set_caption("Drawing Lines")
while True:
for event in pygame.event.get():
if event.type == KEYDOWN and event.key == K_DOWN:
sys.exit()
screen.fill((0,80,0))
color = 100,255,200
width = 8
pygame.draw.line(screen, color, (100,100), (500,400), width)
pygame.display.update()
for some reason, I can't get this is work:
while True:
for event in pygame.event.get():
if event.type == KEYDOWN and event.key == K_DOWN:
sys.exit()
It doesnt show any error, it just doesnt work. I want to be able to press the down key and have it quit the program but it doesnt do that. I have to quit the idle. Any help will do. thanks.
This is because KEYDOWN is just the event that a key is pressed down, not that the down key has been pushed. To fix this, you have to first check if a KEYDOWN event has happened, and if it has, check what key that was pushed.
for event in pygame.event.get():
if event.type == KEYDOWN and event.key == K_DOWN:
sys.exit()
