如何允许在pygame的这个输入框程序中使用大写字母

Question

我在网上找到了这个输入框模块，但它只允许小写而不允许大写。所以有人能告诉我在模块中改变什么，以允许caps作为我创建一个小型多人游戏，我需要登录系统和聊天框。

下面是我正在使用

的代码示例

# by Timothy Downs, inputbox written for my map editor
# This program needs a little cleaning up
# It ignores the shift key
# And, for reasons of my own, this program converts "-" to "_"
# A program to get user input, allowing backspace etc
# shown in a box in the middle of the screen
# Called by:
# import inputbox
# answer = inputbox.ask(screen, "Your name")
#
# Only near the center of the screen is blitted to
import pygame, pygame.font, pygame.event, pygame.draw, string
from pygame.locals import *
def get_key():
  while 1:
    event = pygame.event.poll()
    if event.type == KEYDOWN:
      return event.key
    else:
      pass
def display_box(screen, message):
  "Print a message in a box in the middle of the screen"
  fontobject = pygame.font.Font(None,18)
  pygame.draw.rect(screen, (0,0,0),
                   ((screen.get_width() / 2) - 100,
                    (screen.get_height() / 2) - 10,
                    200,20), 0)
  pygame.draw.rect(screen, (255,255,255),
                   ((screen.get_width() / 2) - 102,
                    (screen.get_height() / 2) - 12,
                    204,24), 1)
  if len(message) != 0:
    screen.blit(fontobject.render(message, 1, (255,255,255)),
                ((screen.get_width() / 2) - 100, (screen.get_height() / 2) - 10))
  pygame.display.flip()
def ask(screen, question):
  "ask(screen, question) -> answer"
  pygame.font.init()
  current_string = []
  display_box(screen, question + ": " + string.join(current_string,""))
  while 1:
    inkey = get_key()
    if inkey == K_BACKSPACE:
      current_string = current_string[0:-1]
    elif inkey == K_RETURN:
      break
    elif inkey == K_MINUS:
      current_string.append("_")
    elif inkey <= 127:
      current_string.append(chr(inkey))
    display_box(screen, question + ": " + string.join(current_string,""))
  return string.join(current_string,"")
def main():
  screen = pygame.display.set_mode((320,240))
  print ask(screen, "Name") + " was entered"
if __name__ == '__main__': main()

谢谢!

如果将对应的代码更改为:

elif inkey <= 127:
    if pygame.key.get_mods() & KMOD_SHIFT or  pygame.key.get_mods() & KMOD_CAPS: # if shift is pressed  or caps is on
        current_string.append(chr(inkey).upper()) # make string uppercase
    else:
        current_string.append(chr(inkey)) # else input is lower 

应该可以。
