如何在 PyGame 中加载多个图像？

我需要在 pygame 中加载大约 200 个图像，以便在游戏中的各个点进行位块传输。我尝试为此编写一个函数，但总是回来NameError: name 'tomato' is not defined.

所有图像名称都是加载图像的变量存储的名称：tomato = pygame.image.load("tomato.png")

使用数组会更好吗，如果是的话我该怎么做？

代码：

def load(image):
    imagename = image
    imagetitle = str(imagename)+".png"
    image = pygame.image.load(imagetitle)
    return image

load("tomato")

def blit_f(fruit):
    gamedisplay.blit(fruit,(0,0))
    pygame.display.update()

fruitlist = []        

running = False
while not running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = True

        if event.type == pygame.MOUSEMOTION:
            mouse = pygame.mouse.get_pos()
            color = screen.get_at(mouse)

            if color == (209,0,0,255):
                blit_f(tomato)
                fruitlist.insert(0,"tomato")

        if event.type == pygame.MOUSEBUTTONDOWN:

            if fruitlist[0] == "tomato":
                gamedisplay.blit(tomato,(0,0))
                pygame.display.update()

仅当导致位块传送的条件时，才会发生 NameErrortomato.png满足：当我将鼠标悬停在番茄图像上时，即红色

如果我写load(tomato)而不是与""，当我运行代码时，NameError 就会出现，并突出显示load(tomato)代替gamedisplay.blit(tomato)至于与load("tomato").

如果你想加载这么多图像，请使用os.listdir https://docs.python.org/3/library/os.html#os.listdir并将目录中的所有图像放入字典中。另外，使用convert or convert_alpha加载图像后以提高性能。

def load_images(path_to_directory):
    """Load images and return them as a dict."""
    image_dict = {}
    for filename in os.listdir(path_to_directory):
        if filename.endswith('.png'):
            path = os.path.join(path_to_directory, filename)
            key = filename[:-4]
            image_dict[key] = pygame.image.load(path).convert()
    return image_dict

如果您还想加载子目录中的所有图像，请使用os.walk:

def load_images(path_to_directory):
    """Load all images from subdirectories and return them as a dict."""
    images = {}
    for dirpath, dirnames, filenames in os.walk(path_to_directory):
        for name in filenames:
            if name.endswith('.png'):
                key = name[:-4]
                img = pygame.image.load(os.path.join(dirpath, name)).convert()
                images[key] = img
    return images
