python - 颜色参数无效

Question

我想向基本游戏的背景添加颜色，但我不断收到无效的颜色参数

我尝试完全删除 bg_color 但仍然给出相同的错误

def run_game():
  pygame.init()
  ai_settings = Settings()
  screen = pygame.display.set_mode((ai_settings.screen_width, ai_settings.screen_height))
  pygame.display.set_caption("First Game")
  ship = Ship(screen)
  bg_color = (230, 230, 230)

  while True:
      check_events(ship)
      ship.update()
      screen.fill(ai_settings, bg_color)
      ship.blitme()
      pygame.display.flip()
      for event in pygame.event.get():
          if event.type==pygame.QUIT:
              sys.exit()
      screen.fill(ai_settings.bg_color)
      ship.blitme()
      pygame.display.flip()
run_game()

screen.fill(ai_settings, bg_color)
TypeError: invalid color argument

Answer 1

fill 仅接受一个参数。并且bg_color不是ai_settings的属性。您需要将线路更改为:

screen.fill(bg_color)
