Pygame Displaying text while paused
<p>I am writing a simple game that could shuffle and display 5 cards from 52 poker when I press "space bar". Everything is working except I want to render a text on screen indicating whether the cards are shuffling or it is the result... Here are the code:</p>

<pre><code>import pygame,sys
from pygame.locals import *

my_clock = pygame.time.Clock()
pygame.init()
color =(200,0,0)
surface_sz = 480
surface = pygame.display.set_mode((surface_sz, surface_sz))
card=pygame.image.load("sprite_sheet_playing_cards.png")
card_width = 73

all_cards=[]
paused=False
text=["Shuffling Cards","Result"]
text_posn=0
my_font = pygame.font.SysFont("Courier", 20)

while True:

    for event in pygame.event.get():

        if event.type == QUIT:
            pygame.quit()
            sys.exit()
        elif event.type == KEYDOWN:
            if event.key == K_SPACE:

                #Shift the text_posn
                text_posn+=1
                text_posn= text_posn%2

                paused = not paused

    surface.fill(color)

    #create 5 crad objects and store them in list
    for card_no in range(5):

        hand_card=cards(card,(50+card_no*card_width,240))
        all_cards.append(hand_card)

    # Start the shuffling
    hand_card.start_shuffle(all_cards,surface)

    #draw the text to surface
    the_text = my_font.render(text[text_posn],True, (0,0,0))
    surface.blit(the_text, (120, 90))

    if paused:
        continue # skip this iteration if paused

    #put everything on display
    pygame.display.flip()

    my_clock.tick(10)
</code></pre>

<p>And here my cards class:</p>

<pre><code>class cards(pygame.sprite.Sprite):
    def __init__(self,img,tar_posn):

        pygame.sprite.Sprite.__init__(self)
        self.image = img
        self.posn = tar_posn
        self.x = 0
        self.y= 0

    def start_shuffle(self,all_cards,target_surface):
        #shuffle the card and draw it on screen
        for one_card in all_cards:
            one_card.shuffle()
            one_card.draw(target_surface)

    def shuffle(self):
        import random
        self.x = random.randint(0,12)
        self.y = random.randint(0,4)


    def draw(self,target_surface):

        patch_rect = (self.x * 73, self.y*98,
                   73, 98)
        target_surface.blit(self.image, self.posn, patch_rect)
</code></pre>

  <p>The word " Shuffling Cards" stuck even I pressed space and changed <code>text_posn</code>.(<code>text_posn</code> did shift between 0 and 1 when pressed space bar) </p>
</blockquote>

<p>I know that the problem is when I paused, I skipped the <code>pygame.display.flip()</code> so I could never update the changed text on screen. Any ideas how I could pause the screen and update the text msg at the same time? Thanks.</p>
