I am getting the above mentioned error on executing this code . This is a example to understand the clock in pygame. Any suggestions how to remove this error
Here is the code
import pygame, sys
from pygame.locals import *
def myquit():
pygame.quit()
sys.exit(0)
def main():
# Initialize Pygame
pygame.init()
# Set up screen
SCREEN_WIDTH = 600
SCREEN_HEIGHT = 480
window = pygame.display.set_mode((SCREEN_WIDTH, SCREEN_HEIGHT))
pygame.display.set_caption('Game Clock') # Set the window bar title
screen = pygame.display.get_surface() # This is where images are displayed
# Set up font
font = pygame.font.Font(None, 36)
# Set up clock
clock = pygame.time.Clock()
FPS = 30
seconds = 0
pygame.time.set_timer(USEREVENT + 1, 1000) # Used to correctly implement seconds
while True: # for each frame
clock.tick(FPS)
screen.fill((255, 255, 255))
time_display = font.render("Time: " + str(clock.get_time()), 1, (0, 0, 0))
rawtime_display = font.render("Raw Time: " + str(clock.get_rawtime()), 1, (0, 0, 0))
fps_display = font.render("FPS: " + str(clock.get_fps()), 1, (0, 0, 0))
pygame_total_ticks_display = font.render("Pygame Ticks (total): " + str(pygame.time.get_ticks()), 1, (0, 0, 0))
seconds_display = font.render("Seconds: " + str(seconds), 1, (0, 0, 0))
screen.blit(time_display, (10, 10))
screen.blit(rawtime_display, (10, 35))
screen.blit(fps_display, (10, 60))
screen.blit(pygame_total_ticks_display, (10, 85))
screen.blit(seconds_display, (10, 110))
for event in pygame.event.get():
if event.type == QUIT:
quit()
elif event.type == KEYDOWN:
if event.key == K_ESCAPE:
myquit()
elif event.type == USEREVENT + 1:
seconds+=1
pygame.display.flip()
main()
