Pygame Program That Can Get Keyboard Input With Caps

I have a Pygame program that needs text input. The way it does this is to get keyboard input and when a key is pressed it renders that key so it is added to the screen. Essentially

Solution 1:

I can use the 'event.unicode' attribute to get the value of the key typed.


Solution 2:

Adding this class to your code should do the trick. To get the character the user presses call the getCharacter function from the class. You can alter the if keyPress >= 32 and keyPress <= 126: statement to allow non letter characters to work with shift.

# The pygame module itself...
import pygame

class controls:

    def getKeyPress(self):
      for event in pygame.event.get():
         if event.type == KEYDOWN:    
             return event.key
         else:
             return False


    def getCharacter(self):

      # Check to see if the player has inputed a command
      keyinput = pygame.key.get_pressed()  

      character = "NULL"

      # Get all "Events" that have occurred.
      pygame.event.pump()
      keyPress = self.getKeyPress()

      #If the user presses a key on the keyboard then get the character
      if keyPress >= 32 and keyPress <= 126:
      #If the user presses the shift key while pressing another character then capitalise it
          if keyinput[K_LSHIFT]: 
              keyPress -= 32

          character = chr(keyPress)

      return character 

Solution 3:

I dig in this question. Every keyboard event in pygame has not only scancode, but the unicode representation. Which not only allow input of capital letters, but also respects multilingual keyboards with language switch.

Here simple 'input/print' example for pygame:

#!/usr/bin/python

import pygame

pygame.init()
screen_size=(800,60)
disp=pygame.display.set_mode(screen_size, pygame.DOUBLEBUF)
msg=u""
clock=pygame.time.Clock()
default_font=pygame.font.get_default_font()
font=pygame.font.SysFont(default_font,16)

disp.fill((240,240,240,255))
pygame.display.flip()
while(not pygame.event.pump()):
    for event in pygame.event.get():
        print event
        if event.type == pygame.QUIT:
            pygame.quit()
            break
        if event.type == pygame.KEYDOWN:
            msg+=event.unicode
            disp.fill((240,240,240,255))
            disp.blit(font.render(msg,True,(30,30,30,255)),(0,0))
            pygame.display.flip()
    clock.tick(24)

Solution 4:

It looks like subtracting 32 should get you what you want, looking at the ASCII table. Make sure you're really dealing with a lowercase letter first though, or you'll get some weird characters. I'm not sure what you mean that capitalization works only on letters:

>>> '1234;!@#abcd'.upper()
'1234;!@#ABCD'

Solution 5:

I wrote a function that converts the strings after getting not enough help. It converts everything manually.
