我在线找到了这个pygame程序，代码如下：
import sys, pygame, random
class Breakout():
def main(self):
xspeed_init = 6
yspeed_init = 6
max_lives = 5

batrect = bat.get_rect()
ball = pygame.image.load("ball.png").convert()
ball.set_colorkey((255, 255, 255))
ballrect = ball.get_rect()
pong = pygame.mixer.Sound('Blip_1-Surround-147.wav')
pong.set_volume(10)
wall = Wall()
wall.build_wall(width)
# Initialise ready for game loop
batrect = batrect.move((width / 2) - (batrect.right / 2), height - 20)

# check if ball has gone past bat - lose a life
if ballrect.top > height:
lives -= 1
# start a new ball
xspeed = xspeed_init
rand = random.random()
if random.random() > 0.5:
xspeed = -xspeed
yspeed = yspeed_init
ballrect.center = width * random.random(), height / 3
if lives == 0:
msg = pygame.font.Font(None,70).render("Game Over", True, (0,255,255), bgcolour)
msgrect = msg.get_rect()

else:

ypos += self.brickheight
self.brickrect.append(self.brick.get_rect())
self.brickrect[i] = self.brickrect[i].move(xpos, ypos)
xpos = xpos + self.bricklength
if __name__ == '__main__':
br = Breakout()
br.main()
该代码工作正常，但是如何在该代码中添加秒表代码？我有一个秒表代码，如下所示：
import pygame
import pygame.freetype
def main():
pygame.init()
screen=pygame.display.set_mode((400, 300))
clock=pygame.time.Clock()
font=pygame.freetype.SysFont(None, 34)
font.origin=True
while True:
for e in pygame.event.get():
if e.type == pygame.QUIT: return
screen.fill(pygame.Color('grey12'))
ticks=pygame.time.get_ticks()
millis=ticks%1000
seconds=int(ticks/1000 % 60)
minutes=int(ticks/60000 % 24)
out='{minutes:02d}:{seconds:02d}:{millis}'.format(minutes=minutes, millis=millis, seconds=seconds)
font.render_to(screen, (100, 100), out, pygame.Color('dodgerblue'))
pygame.display.flip()
clock.tick(60)
if __name__ == '__main__': main()
我应该在哪里将此代码添加到主游戏中，以便玩家可以知道他/她玩了多长时间了。我还是这个python程序的新手。还在学习。
答案 0 :(得分：0)
您只需将计时器插入main类的Breakout方法中即可。
import pygame.freetype
font = pygame.freetype.SysFont(None, 34)
class Breakout():
def main(self):
# Other code omitted ...
while 1:
clock.tick(60)
for event in pygame.event.get():
# ...
ticks = pygame.time.get_ticks()
millis = ticks%1000
seconds = int(ticks/1000 % 60)
minutes = int(ticks/60000 % 24)
out = f'{minutes:02d}:{seconds:02d}:{millis}'
# In the drawing section before pygame.display.flip gets called.
font.render_to(screen, (10, 30), out, pygame.Color('dodgerblue'))
pygame.display.flip()
如果您想在游戏结束后重置计时器，请查看以下计时器之一：Countdown timer in Pygame
