按住键时如何移动精灵

Question

目前，每次按键时，精灵仅移动1个像素。按住左右键时，如何使水暖工精灵不断移动？

while running:
    setup_background()
    spriteimg = plumberright

    screen.blit(spriteimg,(x1, y1))

    for event in pygame.event.get():
         if event.type == pygame.QUIT:
             running = False
         elif event.type == pygame.KEYDOWN:
             if event.key == pygame.K_UP:
                 x1 = x1 + 0
                 y1 = y1 - 1
             elif event.key == pygame.K_DOWN:
                 x1 = x1 + 0
                 y1 = y1 + 1
             elif event.key == pygame.K_LEFT:
                 x1 = x1 -1
                 y1 = y1 + 0
             elif event.key == pygame.K_RIGHT:
                 x1 = x1 + 1
                 y1 = y1 + 0

    pygame.display.flip()
    clock.tick(120)

您可以使用pygame.key.get_pressed来做到这一点。

例：

while running:
    keys = pygame.key.get_pressed()  #checking pressed keys
    if keys[pygame.K_UP]:
        y1 -= 1
    if keys[pygame.K_DOWN]:
        y1 += 1
