Pygame MemoryError

嗨，我编写了一个简单的块收集程序，在我添加声音之前，它的工作原理还不错。然后突然我得到了MemoryError，这是我以前从未见过的东西。

我的代码与声音（wav）文件一起附加，这似乎是问题所在。任何帮助都将是非常有用的，是的，代码和声音以及大量其他程序和图片均在同一个文件夹中。

Pass in the color of the block and its x and y pos.    def __init__(self, color, width, height):            # Call the parent class (Sprite) constructor            pygame.sprite.Sprite.__init__(self)            # Create an image of the block, and fill it with a color.            # This could also be an image loaded from the disk.            self.image = pygame.Surface([width, height])            self.image.fill(color)            # Fetch the rectangle object that has the dimensions of the image            # image.            # Update the position of this object by setting the values             # of rect.x and rect.y            self.rect = self.image.get_rect()# Initialize Pygamepygame.init()winsound=pygame.mixer.Sound(''winning.wav'')collectsound=pygame.mixer.Sound(''blip.wav'')#Set width and height of screenscreen_width=700screen_height=400screen=pygame.display.set_mode([screen_width, screen_height])pygame.display.set_caption(''Block Attack!'')#List of sprites.

所以当我运行代码时我得到了错误

Traceback (most recent call last):  File "/Users/zackbaker/Desktop/PythonFolder/BlockCollecter.py", line 4, in <module>    sound=pygame.mixer.Sound(''winning.wav'')MemoryError

答案1

我认为您必须先初始化调音台，然后才能使用声音。

pygame.mixer.init(44100, -16, 2, 2048)# Read the docs to know what these numbers are
