1.参考官方文档
https://www.pygame.org/docs/ref/key.html#pygame.key.set_repeat
2.实现功能代码
pygame.key.set_repeat(pygame.KEYDOWN,10) # 实现重复按下的功能，间隔10毫秒
3.案例代码
wasd键控制方向
import sys, pygame
pygame.init()
size = width, height = 500, 400
black = 0, 0, 0
screen = pygame.display.set_mode(size)
ball = pygame.image.load("intro_ball.gif")
ballrect = ball.get_rect()
pygame.key.set_repeat(pygame.KEYDOWN,10) # 实现重复按下的功能，间隔10毫秒
while 1:
for event in pygame.event.get():
if event.type == pygame.QUIT:
sys.exit()
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_a:
ballrect = ballrect.move([-5,0])
if event.key == pygame.K_d:
ballrect = ballrect.move([5,0])
if event.key == pygame.K_w:
ballrect = ballrect.move([0,-5])
if event.key == pygame.K_s:
ballrect = ballrect.move([0,5])
screen.fill(black)
screen.blit(ball, ballrect)
pygame.display.flip()
