title: Edited joystick code not receiving inputs
body: <p>I am trying to use a ps4 controller with a raspberry pi to generate inputs. I have sucessfully connected the controller and when i try and run the following code found on the pygame website everything is working fine. </p>
  
  <pre><code>import pygame
  
  
  BLACK    = (   0,   0,   0)
  WHITE    = ( 255, 255, 255)
  
  
  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() 
  size = [500, 700]
  screen = pygame.display.set_mode(size)
  pygame.display.set_caption("My Game")
  
  
  done = False
  
  clock = pygame.time.Clock()
  
  
  pygame.joystick.init()
  
  
  textPrint = TextPrint()
  
  
  while done==False:
  
      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
  
         JOYBUTTONUP JOYHATMOTION
          if event.type == pygame.JOYBUTTONDOWN:
              print("Joystick button pressed.")
          if event.type == pygame.JOYBUTTONUP:
              print("Joystick button released.")
  
  
  
      screen.fill(WHITE)
      textPrint.reset()
  
      joystick_count = pygame.joystick.get_count()
  
      textPrint.print(screen, "Number of joysticks: {}".format(joystick_count) )
      textPrint.indent()
  
  
      for i in range(joystick_count):
          joystick = pygame.joystick.Joystick(i)
          joystick.init()
  
          textPrint.print(screen, "Joystick {}".format(i) )
          textPrint.indent()
  
          name = joystick.get_name()
          textPrint.print(screen, "Joystick name: {}".format(name) )
  
          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: {:&gt;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 {:&gt;2} value: {}".format(i,button) )
          textPrint.unindent()
  
  
          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()
  
  
  
      pygame.display.flip()
  
  
      clock.tick(20)
  
  pygame.quit ()
  </code></pre>
  
  <p>So yeah when i run the above code everything works fine, however i didn't want to generate a game at all, and i'm only interested in getting the inputs from the d pad or the hats. in order to do this i wrote my own code based  off the code above</p>
  
  <pre><code> import pygame
      pygame.joystick.init()
      while True:
          joystick = pygame.joystick.Joystick(0)
          joystick.init()
          hat = joystick.get_hat(0)
          print(str(hat))
  </code></pre>
  
  <p>When i run the above code it runs and there are no syntax errors, however it continuously prints(0,0) regardless of what buttons of the d-pad i have pressed. The controller is still connected, which suggests to me that for some reason my new code isn't recieving inputs.</p>
  
  <p>Thank you for taking the time to read this long post, any help would be much appreciated.</p>
  
  <p>Kind regards</p>
