我正在用pygame制作赛车游戏。当汽车撞到其中一堵墙时，应该显示“ YOU CRASHED”消息。它正在执行此操作，但是只显示了不到一秒钟，然后重置了游戏，您不得不再次玩。我发出命令来显示文本的地方是def_crash()。
这是游戏的代码：
import time

pygame.init()
display_width = 800
display_height = 600
black = (0,0,0)
white = (255,255,255)

bright_red = (255,0,0)

car_width = 86
gameDisplay = pygame.display.set_mode((display_width,display_height))
pygame.display.set_caption("Racing Game")
clock = pygame.time.Clock()
carImg = pygame.image.load("download.png")
carImg = pygame.transform.scale(carImg,(100,160))
def things_dodged(count):
font = pygame.font.SysFont(None, 25)
text = font.render ("Dodged: "+str(count), True, black)
gameDisplay.blit(text,(0,0))
def things(thingx, thingy, thingw, thingh, color):
pygame.draw.rect(gameDisplay, color, [thingx, thingy, thingw, thingh])
def car(x,y):
gameDisplay.blit(carImg, (x,y))
def text_objects(text, font):

gameDisplay.blit(TextSurf, TextRect)

Please help if possible. If you can tell me what's wrong and tell me how to fix it that would be great.

一种快速而肮脏的方法是做这样的事情。我所做的只是您的crash函数，并在调用它的位置添加了一些代码。我还删除了display_message中的某些行。
import pygame
import time
pygame.init()
display_width = 800
display_height = 600
black = (0,0,0)
white = (255,255,255)
red = (255,0,0)
car_width = 86
gameDisplay = pygame.display.set_mode((display_width,display_height))
pygame.display.set_caption("Racing Game")
clock = pygame.time.Clock()
carImg = pygame.image.load("download.png")
carImg = pygame.transform.scale(carImg,(100,160))
def car(x,y):
gameDisplay.blit(carImg, (x,y))
def text_objects(text, font):
textSurface = font.render(text, True, black)
return textSurface, textSurface.get_rect()
def message_display(text):
largeText = pygame.font.Font("freesansbold.ttf",100)
TextSurf, TextRect = text_objects(text, largeText)
TextRect.center = ((display_width/2),(display_height/2))
gameDisplay.blit(TextSurf, TextRect)
# Don't do any of these.
# pygame.display.update()
# game_loop()
# time.sleep(2)
def crash_scene(x, y):
sceneExit = False
time = 2000 # 2000 milliseconds until we continue.
while not sceneExit:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
quit()
gameDisplay.fill(white)
car (x,y)
message_display ("YOU CRASHED")
pygame.display.update()
passed_time = clock.tick(60)
time -= passed_time
if time <= 0:
sceneExit = True
def game_loop():
x = (display_width * 0.45)
y = (display_height * 0.72)
x_change = 0
gameExit = False
while not gameExit:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
quit()
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_LEFT:
x_change = -5
if event.key == pygame.K_RIGHT:
x_change = 5
if event.type == pygame.KEYUP:
if event.key == pygame.K_LEFT or event.key == pygame.K_RIGHT:
x_change = 0
x += x_change
gameDisplay.fill(white)
car (x,y)
if x > display_width - car_width or x < -10:
crash_scene(x, y)
# Reset car
x = (display_width * 0.45)
y = (display_height * 0.72)
x_change = 0
pygame.display.update()
clock.tick(60)
game_loop()
pygame.quit()
quit()
基本上，当您需要更改事件的处理方式，游戏对象的更新方式或绘制方式时，请为此创建一个自己的小函数。其他示例是菜单，暂停屏幕或过场动画。在上面的示例中，我做了绝对的起步，因此代码存在一些问题，但是应该可以。
