我正在嘗試為我的 pygame 游戲中的每個對象繪制一個碰撞箱，但碰撞箱沒有顯示。這是我定義hitbox和敵人其他方面的類。class Enemy:    def __init__(self, y, width, height):        self.width = width        self.height = height        self.vel = 1.5        self.y = y        self.x = random.randrange(screen_width - 64 * 2)        self.index = random.choice(number)        self.hitboxes = [(self.x + 68, self.y + 68, self.width - 10, self.height - 14),                         (self.x + 38, self.y + 47, self.width + 20, self.height - 5),                         (self.x + 18, self.y + 12, self.width + 32, self.height + 30),                         (self.x + 20, self.y + 32, self.width + 16, self.height + 5),                         (self.x + 4, self.y + 7, self.width - 24, self.height - 31)]  # hitbox list        self.hitbox = self.hitboxes[self.index]  # selecting hitbox from list      def draw(self, win):        win.blit(asteroids[self.index], (self.x, self.y))        pygame.draw.rect(win, (255, 0, 0), self.hitbox, 2)  # trying to draw the hitbox 這是re_draw功能def re_draw():    win.fill((0, 0, 0))    [...]    for a in asteroids_on_screen:        a.draw(win)  # this is where I draw the object     [...]    pygame.display.update()這是主循環和與我想在其上顯示 hitbox 的敵人/對象關聯的變量。asteroids = [pygame.image.load('rock0.png'), pygame.image.load('rock1.png'), pygame.image.load('rock2.png'),             pygame.image.load('rock3.png'), pygame.image.load('rock4.png')]number = [0, 1, 2, 3, 4]asteroids_on_screen = []rock = Enemy(-140, 64, 64)[...]run = Truewhile run:    last = pygame.time.get_ticks()    for event in pygame.event.get():        if event.type == pygame.QUIT:            run = False        elif event.type == my_event_id:            x = random.randrange(screen_width - 64 * 2)            index = random.choice(number)            asteroids_on_screen.append(Enemy(rock.y, rock.width, rock.height))
