import pygame个
pygame.init()
screen = pygame.display.set_mode((700, 700))
pygame.display.set_caption('Checkers')
while True:
screen.fill((114,157,224))
pygame.display.update()
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
elif event.type == pygame.KEYDOWN:
if event.key == pygame.K_a:
screen.fill((70,44,133))
pygame.display.update()
我试着把pygame.KEYDOWN改成pygame.key.get_pressed()，但什么都没变.
您应该更新每一帧中的显示，但当按下按钮时，您必须将显示使用的Color更改为fill:
clock = pygame.time.Clock()
fillColor = pygame.Color(114,157,224)
run = True
while run:
clock.tick(100)
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
elif event.type == pygame.KEYDOWN:
if event.key == pygame.K_a:
fillColor = pygame.Color(70,44,133)
screen.fill(fillColor)
# draw scene
# [...]
pygame.display.update()
pygame.quit()
典型的PyGame应用程序循环必须:
pygame.time.Clock.tickpygame.event.pump()或pygame.event.get()来处理这些事件.blit个所有对象)pygame.display.update()或pygame.display.flip()更新显示屏
