Pygame NameError：名称“图像”未定义

Question

我正在修改我在网上找到的一个程序，我正在尝试加载一个 .png 而不是以前的块精灵，但我认为我在尝试加载它时编码不正确。代码如下：

class Player(pygame.sprite.Sprite):
    """
    This class represents the bar at the bottom that the player controls.
    """

    # -- Methods
    def __init__(self):
        """ Constructor function """

        # Call the parent's constructor
        super().__init__()

        # Create an image of the block, and fill it with a color.
        # This could also be an image loaded from the disk.
        image.self.pygame ("Sprite-01.png")

        # Set a referance to the image rect.
        self.rect = self.image.get_rect()

        # Set speed vector of player
        self.change_x = 0
        self.change_y = 0

        # List of sprites we can bump against
        self.level = None

这是错误：

Traceback (most recent call last):

    player = Player()

    image.self.pygame ("Sprite-01.png") 
NameError: name 'image' is not defined

Answer 1

image.self.pygame ("Sprite-01.png")

将该行更改为：

self.image = pygame.image.load("Sprite-01.png").convert_alpha()

如果图像没有透明部分，则只需 .convert()。

我还建议在程序启动之前将图像加载到全局范围或其他模块中，然后重用它们而不是再次加载它们。从硬盘读取速度很慢。
