python - ' bool 对象不可调用'pygame

Question

尝试重新分配实例的 x 和 y 值时出现“bool object is not callable”错误。我不相信我正在调用一个“bool”对象。唯一的可能性是将 self.selected 重新分配给 False，但我试图摆脱那条线并得到同样的错误。怎么了？

报错的函数:

    class Pawns(Pieces):
        def __init__(self, x, y, image):
            Pieces.__init__(self, x, y, image)
            self.upgrade = False


        def move(self):
            if self.selected:
                if self.x+80 > cursor[0] > self.x and self.y-80 > 
    cursor[1] > self.y and click[0]:
                    self.y -= 80
                    self.selected = False

函数在这里被调用。我将实例按类存储为列表，这就是为什么我有嵌套循环。

    for pawn in wpawns:
            pawn.move()

    for character in characters:
        for piece in character:
                piece.draw(win)

错误:

请询问是否需要任何说明。感谢您的帮助。

在您的 pieces 类中，您将 move 设置为 bool 值。

因为 Pawns 继承自 Pieces 它接收此属性。

class Pieces:
    def __init__(self, x, y, image):
        self.x = x
        self.y = y
        self.image = image
        self.isAlive = True
        self.selected = False
        self.move = False
        self.hitbox = (self.x, self.y, 80, 80)

另外，因为您从 Pawns 调用了 super 方法 init，所以这些属性也在 Pawns 中实例化。

class Pawns(Pieces):
    def __init__(self, x, y, image):
        Pieces.__init__(self, x, y, image)
        self.upgrade = False

将它从 __init__ 中移除，它应该可以工作。
