如何旋转图像pygame的口罩

Question

嗨，我在旋转旋转掩码的对象面罩上遇到麻烦，仍然与原始图像相同。关键是要在赛道上移动面膜形式碰撞。

    def __init__(self, x, y , height , width):
        self.x = x - width / 2
        self.y = y - height / 2
        self.height = height
        self.width = width
        self.car_img = pygame.image.load('img/auticko.png').convert_alpha()
        self.car_rect = self.car_img.get_rect()
        self.car_mask = pygame.mask.from_surface(self.car_img)
        self.surface = pygame.Surface((height, width),pygame.SRCALPHA)

        self.surface.blit(self.car_img, (0, 0))
        self.angle = 0
        self.speed = 2
    def draw(self,screen):  # 3
        self.car_rect.topleft = (int(self.x), int(self.y))
        rotated = pygame.transform.rotate(self.surface, self.angle)
        #rotated.set_colorkey((0, 0, 0))
        surface_rect = self.surface.get_rect(topleft=self.car_rect.topleft)
        new_rect = rotated.get_rect(center=surface_rect.center)
        screen.blit(rotated, new_rect.topleft)

我试图从表面制作新面具，但它不起作用 正如您在图像上看到的那样，转动汽车不应该是 在此处输入图像描述

您无法旋转蒙版，但可以在旋转图像后创建新蒙版：

rotated = pygame.transform.rotate(self.surface, self.angle)
self.car_mask = pygame.mask.from_surface(rotated)
