在Python中向内置类添加属性？（用于检测tic tac toe中的win）

Question

我正在用Pygame用Python编写一个tic-tac-toe游戏。我需要在我的循环中检查是否有任何赢家（连续3个或对角3个）。我使用for循环和矩形位置（Pygame中的内置类）绘制零和十字

是否可以将我自己的属性设置为内置类（pygame.rect），例如

sq1.isFull = True

…即使这不是rect的内置方法

如果不是，如果我所有的方块和圆圈都是在for循环中生成的，我将如何检查赢家

代码如下所示：

import pygame

# initialize pygame
pygame.init()

# window setup
screen = pygame.display.set_mode((550, 550))
pygame.display.set_caption('Tic Tac Toe by Donnaven')

# squares
sq1 = pygame.draw.rect(screen, (255, 255, 255), (25, 25, 150, 150))
sq2 = pygame.draw.rect(screen, (255, 255, 255), (200, 25, 150, 150))
sq3 = pygame.draw.rect(screen, (255, 255, 255), (375, 25, 150, 150))

sq4 = pygame.draw.rect(screen, (255, 255, 255), (25, 200, 150, 150))
sq5 = pygame.draw.rect(screen, (255, 255, 255), (200, 200, 150, 150))
sq6 = pygame.draw.rect(screen, (255, 255, 255), (375, 200, 150, 150))

sq7 = pygame.draw.rect(screen, (255, 255, 255), (25, 375, 150, 150))
sq8 = pygame.draw.rect(screen, (255, 255, 255), (200, 375, 150, 150))
sq9 = pygame.draw.rect(screen, (255, 255, 255), (375, 375, 150, 150))

square_list = [sq1, sq2, sq3, sq4, sq5, sq6, sq7, sq8, sq9]

# game loop
pTurn = True  # Whose turn it is.
# True = Rectangle, False = Circle
running = True

while running:
    pygame.time.delay(100)

    # checking for events
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

        if event.type == pygame.MOUSEBUTTONUP:
            mouse_pos = pygame.mouse.get_pos()

            for square in square_list:
                if square.collidepoint(mouse_pos):
                    square_x = square.x
                    square_y = square.y

                    # draw shape inside of square
                    if pTurn:  # rectangle player turn
                        pygame.draw.rect(screen, (255, 0, 0), (square_x + 25, square_y + 25, 100, 100))
                        pTurn = False
                    elif not pTurn:  # circle player turn
                        pygame.draw.circle(screen, (0, 255, 0), (square_x + 75, square_y + 75), 60)
                        pTurn = True

    # update frame (DONE LAST!)
    pygame.display.update()

如果要向类添加属性，请使用Inheritance。创建具有子类pygame.Rect的类MyRect：

class MyRect(pygame.Rect):
    def __init__(self, x, y, w, h, isFull = True):
        super().__init__(x, y, w, h)
        self.isFull = isFull

但是，您也应该考虑创建一个用于聚集^ {< CD2>}：

的块的类。

class MyTile:
    def __init__(self, x, y, w, h, isFull = True):
        self.rect = pygame.Rect(x, y, w, h)
        self.isFull = isFull

这将允许您使MyTile成为^{}的子类：

class MyTile(pygame.sprite.Sprite):
    def __init__(self, x, y, w, h, isFull = True):
        super().__init__()
        self.rect = pygame.Rect(x, y, w, h)
        self.isFull = isFull
        self.image = pygame.Surface(self.rect.size)
        self.image.fill((255, 0, 0)) # just for example

Answer 2

不是直接的，但是您可以创建一个包装类，a-la组合

class Tile:
    def __init__(self, square):
        self.square = square
        self.is_full = False

square_list = [Tile(sq1), ... Tile(sqn)]

for tile in square_list:
    square = tile.square
    if square.collidepoint(mouse_pos) and not tile.is_full:
        ...
        tile.is_full = True
