如何在pygame的这个输入框程序中允许大写? [英] How to allow caps in this input box program for pygame?

问题描述

我在互联网上找到了这个输入框模块，但它只允许小写不能大写.那么有人可以告诉我在模块中进行哪些更改以允许大写，因为我正在创建一个小型多人游戏并且我需要登录系统和聊天框.

I found this input box module on the internet but it only allows lower case no upper. So could someone tell me what to change in the module to allow caps as im creating a small multiplayer game and i need login system and chatbox.

这是我正在使用的代码示例

Here is the code example I am working with

# 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！

推荐答案

如果将对应的代码改为:

If you change the corresponding code to:

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.
