我正在编写一个简单的游戏,当我按下“空格键”时,它可以洗牌并显示 52 张扑克中的 5 张牌。一切正常,除了我想在屏幕上呈现一个文本,指示牌是在洗牌还是结果......这是代码:
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)
这里是我的卡片类:
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)
即使我按空格键并更改,“洗牌”一词也会卡住
text_posn
。(text_posn
按空格键时确实在 0 和 1 之间移动)
我知道问题是当我暂停时,我跳过了,pygame.display.flip()
所以我永远无法更新屏幕上更改的文本。有什么想法可以暂停屏幕并同时更新文本消息吗?谢谢。
