Question

我正在为我的游戏导入背景图片，但是我一直收到此错误：

"File "/Users//PycharmProjects/Platformer/levels.py", line 75, in __init__
self.background.set_colorkey(constants.WHITE)
AttributeError: 'SpriteSheet' object has no attribute 'set_colorkey'".

我已将名为spritesheet_functions.py的文件导入到我正在使用的文件中。但是，我确定我的set_colorkey类中有一个SpriteSheet命令，因此有人可以解决此问题吗？

import pygame
from os import path
import constants

img_dir = path.join(path.dirname(__file__), 'IMG')


class SpriteSheet(object):
    """ Class used to grab images out of a sprite sheet. """

    def __init__(self, file_name):
        """ Constructor. Pass in the file name of the sprite sheet. """

        # Load the sprite sheet.
        self.sprite_sheet = pygame.image.load(path.join(img_dir, 
                                             file_name)).convert()

    def get_image(self, x, y, width, height):
        """ Grab a single image out of a larger spritesheet
             Pass in the x, y location of the sprite
            and the width and height of the sprite. """

        # Create a new blank image
        image = pygame.Surface([width, height]).convert()

        # Copy the sprite from the large sheet onto the smaller image
        image.blit(self.sprite_sheet, (0, 0), (x, y, width, height))

        # Assuming black works as the transparent color
        image.set_colorkey(constants.BLACK)

        # Return the image
        return image


class Level01(Level):
     """ Definition for level 1. """

     def __init__(self, player):
    """ Create level 1. """

        # Call the parent constructor
        Level.__init__(self, player)

        self.background = SpriteSheet('background_01.png')
        self.background.set_colorkey(constants.WHITE)
        self.level_limit = -2500

您在

中以错误的方式使用set_colorkey

self.background = SpriteSheet('background_01.png')
self.background.set_colorkey(constants.WHITE)

完整的错误消息应该显示它。

self.background是类SpriteSheet的实例，不是具有Surface

的set_colorkey的实例

可能您必须在set_colorkey的{{1}}上使用SpriteSheet.sprite_sheet

Surface

如何解决：“ AttributeError：'SpriteSheet'对象没有属性'set_colorkey'”？
