在Pygame中移動時替換圖片

Question

我在Pygame中移動屏幕時可以看到這個圖片。我想要做的是每隔一段時間輪換一次。因此，我希望它以image1.png開頭，然後在頁面中移動，在human1.png和human2.png之間切換，然後在image1.png上完成。這可能嗎？

我的代碼是：

if (human1_position.left <= 555): 
    human1_position = human1_position.move(2, 0) # move first human 
    pygame.display.update() 
else: 
    move = STOP 
screen.blit(human1, human1_position) 

感謝

這裏是一個可能的解決方案：

# Before main loop 
human_files = ["human1.png", "human2.png"] 
human_sprites = [pygame.image.load(filename).convert_alpha() for filename in human_files] 
human1_index = 0 

... 

# During main loop 
if (human1_position.left <= 555): 
    human1_position = human1_position.move(2, 0) # move first human 
    human1_index = (human_index + 1) % len(human_sprites) # change sprite 
else: 
    move = STOP 
    human1_index = 0 
human1 = human_sprites[human1_index] 
screen.blit(human1, human1_position) 
pygame.display.update() 

我感動的更新（）調用，它應該會出現每幀只有一次畢竟已被繪製。
