Pygame с ввода текста Проблемы

Question

Запуск на Python 2.7 с Pygame 1.9

Моя проблема в том, что мне нужен ввод текста в маленькой игре я строил с Pygame. Итак, оглядевшись, я увидел this, что позволило пользователю вводить данные. Eztext (ссылка выше) предоставила отличный способ представить пользователю текстовую область. Но мне понадобился текст этой текстовой области, как только пользователь нажал кнопку ввода.

Итак, имея это в виду, я изменил нижнюю часть функции обновления в файле eztext, чтобы вернуть значение текстового поля.

elif event.key == K_RETURN: 
    return self.value 
    self.value = "" 

Теперь, в моем основном цикле в отдельном файле, я проверяю, не возвращает ли возвращаемое значение значение null, а затем воздействует на результат.

events = pygame.event.get() 
msgvalue = txtbox.update(events) 
if msgvalue is not None: 
    break # Out of the main loop, so the program closes. 

Однако, когда я нажимаю enter в текстовом поле, ничего не происходит. Кажется, что функция update ничего не возвращает. Вот полная модифицированная функция:

def update(self, events): 
    """ Update the input based on passed events """ 
    for event in events: 
     if event.type == KEYUP: 
      if event.key == K_LSHIFT or event.key == K_RSHIFT: self.shifted = False 
     if event.type == KEYDOWN: 
      if event.key == K_BACKSPACE: self.value = self.value[:-1] 
      elif event.key == K_LSHIFT or event.key == K_RSHIFT: self.shifted = True 
      elif event.key == K_SPACE: self.value += ' '

Answer 1

не могу поверить, что я не видел этого раньше, но если я правильно читать ваш код, обновление только путь() обнаружит K_return, если вы держите вниз сдвиг.

Попробуйте переместить применимый объект на часть условного выражения, которое является истинным, если вы не удерживаете клавишу сдвига.
