Hi i'm using pygame for a school project but it seems to not work correctly. First of all i try to use it with a gamepad and to make it return me joystick position but even when i use their own program
import pygame
# Define some colors
BLACK = ( 0, 0, 0)
WHITE = ( 255, 255, 255)
# This is a simple class that will help us print to the screen
# It has nothing to do with the joysticks, just outputing the
# information.
class TextPrint:
def __init__(self):
self.reset()
self.font = pygame.font.Font(None, 20)
def print(self, screen, textString):
textBitmap = self.font.render(textString, True, BLACK)
screen.blit(textBitmap, [self.x, self.y])
self.y += self.line_height
def reset(self):
self.x = 10
self.y = 10
self.line_height = 15
def indent(self):
self.x += 10
def unindent(self):
self.x -= 10
pygame.init()
# Set the width and height of the screen [width,height]
size = [500, 700]
screen = pygame.display.set_mode(size)
pygame.display.set_caption("My Game")
#Loop until the user clicks the close button.
done = False
# Used to manage how fast the screen updates
clock = pygame.time.Clock()
# Initialize the joysticks
pygame.joystick.init()
# Get ready to print
textPrint = TextPrint()
# -------- Main Program Loop -----------
while done==False:
# EVENT PROCESSING STEP
for event in pygame.event.get(): # User did something
if event.type == pygame.QUIT: # If user clicked close
done=True # Flag that we are done so we exit this loop
# Possible joystick actions: JOYAXISMOTION JOYBALLMOTION JOYBUTTONDOWN JOYBUTTONUP JOYHATMOTION
if event.type == pygame.JOYBUTTONDOWN:
print("Joystick button pressed.")
if event.type == pygame.JOYBUTTONUP:
print("Joystick button released.")
# DRAWING STEP
# First, clear the screen to white. Don't put other drawing commands
# above this, or they will be erased with this command.
screen.fill(WHITE)
textPrint.reset()
# Get count of joysticks
joystick_count = pygame.joystick.get_count()
textPrint.print(screen, "Number of joysticks: {}".format(joystick_count) )
textPrint.indent()
# For each joystick:
for i in range(joystick_count):
joystick = pygame.joystick.Joystick(i)
joystick.init()
textPrint.print(screen, "Joystick {}".format(i) )
textPrint.indent()
# Get the name from the OS for the controller/joystick
name = joystick.get_name()
textPrint.print(screen, "Joystick name: {}".format(name) )
# Usually axis run in pairs, up/down for one, and left/right for
# the other.
axes = joystick.get_numaxes()
textPrint.print(screen, "Number of axes: {}".format(axes) )
textPrint.indent()
for i in range( axes ):
axis = joystick.get_axis( i )
textPrint.print(screen, "Axis {} value: {:>6.3f}".format(i, axis) )
textPrint.unindent()
buttons = joystick.get_numbuttons()
textPrint.print(screen, "Number of buttons: {}".format(buttons) )
textPrint.indent()
for i in range( buttons ):
button = joystick.get_button( i )
textPrint.print(screen, "Button {:>2} value: {}".format(i,button) )
textPrint.unindent()
# Hat switch. All or nothing for direction, not like joysticks.
# Value comes back in an array.
hats = joystick.get_numhats()
textPrint.print(screen, "Number of hats: {}".format(hats) )
textPrint.indent()
for i in range( hats ):
hat = joystick.get_hat( i )
textPrint.print(screen, "Hat {} value: {}".format(i, str(hat)) )
textPrint.unindent()
textPrint.unindent()
# ALL CODE TO DRAW SHOULD GO ABOVE THIS COMMENT
# Go ahead and update the screen with what we've drawn.
pygame.display.flip()
# Limit to 20 frames per second
clock.tick(20)
# Close the window and quit.
# If you forget this line, the program will 'hang'
# on exit if running from IDLE.
pygame.quit ()
It detect the gamepad but doesn't return me anything buttons/hats/joystick all the value stays at 0.
Even when i try it with my keyboard it detect the device but always return me 0 even when keys are pressed with pygame.key.get_pressed()
The problem is that i dont have a gamepad to experiment most of the time, so i tried with my keyboard to detect key which are pressed but i doesn't work either. My program was :
import pygame
import time
pygame.init()
while True:
print(pygame.key.get_pressed())
time.sleep(3)
But it doesn't matter which keys are pressed the value remains to 0 for all of them

Try going through and initializing all the joysticks only once outside of the loop and then remove the code that initializes them that's currently inside the loop. It may be that when you do that it clears-out some sort of input buffer giving you zeroed-out values. But without having a gamepad on hand to test this theory, this is just my guess.
