Question

this constructor takes no arguments 错误

class PlatformSprite(Sprite): def __init__(self, game, photo_image, x, y, width, height): Sprite.__init__(self, game) self.photo_image = photo_image self.image = game.canvas.create_image(x, y, image=self.photo_image, anchor='nw') self.coordinates = Coords(x, y, x + width, y + height)TypeError: this constructor takes no arguments
self.coordinates = Coords(x, y, x + width, y + height)
TypeError: this constructor takes no arguments

关于Coords:
class Coords:
def __int__(self, x1=0, y1=0, x2=0, y2=0):
self.x1 = x1
self.y1 = y1
self.x2 = x2
self.y2 = y2

Answer 1

self.__init__() 和Coords应该不需要输入argument的吧，否则这个error说不通，只有可能argument不应该被输入。arguement输入的数量不同会有别的提示的。

Answer 2

你确定sprite类的构造函数需要传入参数？
