（Pygame）.blit在运行时不会显示

Question

所以我尝试创建一个计时器，当游戏运行时，游戏运行的秒数会显示在我的pygame窗口中。但由于某种原因，它似乎不起作用。我不太清楚到底是什么问题。你知道吗

第35-44行是定时器功能的所在。。。 第71行是显示时间的地方。。。你知道吗

import pygame

pygame.init()
pygame.font.init()

FPS = 60
fpsClock = pygame.time.Clock()

time = 10

WHITE = (255,255,255)

dimension = [936, 520]

SCREEN = pygame.display.set_mode(dimension)

font = pygame.font.Font("8-BIT WONDER.TTF",16)

gameEnd= False

#Images
blacksmith = pygame.image.load("blacksmith.png")
blacksmith = pygame.transform.scale(blacksmith,(144,144))

background = pygame.image.load("background_img.png")

#Positions
blacksmith_position = [400,275]

anvil_position = [0,0]

song = pygame.mixer.music.load("Pixelland.mp3")
pygame.mixer.music.play(0, 0.0)

#Time
get_time = True

#Clock
while get_time == True:
    time = pygame.time.get_ticks() / 1000
    pygame.time.delay(1000)

display_time = font.render(time, True, WHITE)

#Game Loop

while not gameEnd:
   for event in pygame.event.get():
      if event.type == pygame.QUIT:
          gameEnd = True



    #Player Controls

   keys = pygame.key.get_pressed()

   if keys[pygame.K_F11]:
       pygame.display.toggle_fullscreen()

   if keys[pygame.K_LEFT]:
       blacksmith_position[0] = max(95, blacksmith_position[0] - 12)

   if keys[pygame.K_RIGHT]:
       blacksmith_position[0] = min(685, blacksmith_position[0] + 12)



   SCREEN.blit(background, (0, 0))
   SCREEN.blit(blacksmith,(blacksmith_position))
   SCREEN.blit(display_time, (70,10))
   pygame.display.update()
   fpsClock.tick(FPS)

pygame.quit()
quit()

Answer 1

运行while get_time == True:可以停止一切。它一直在运行。你知道吗

您只能有一个一直运行的while循环（无限循环）-mainloop。你知道吗
