我收到以下错误。TypeError：参数1必须是pygame.Surface，而不是str
我一直在看我如何格式化图像，似乎没有什么错。无论如何，这是我的代码：

顺便说一下，这些图像显然不会为您加载，因此，如果要运行它，只需获取任何jpeg图像并将其命名为“ blue-car-hi.png”或其他名称，以在其中显示图像地点。
您在方法self.image中将汽车的设置为，但这是一个字符串，而不是pygame.Surface。该有同样的问题。CAR_IMAGE_RIGHTmove_car_rightmove_car_left
CAR_IMAGE_RIGHT = "blue-car-hi.png"
def move_car_right(self):
self.rect.x+=4
self.image = CAR_IMAGE_RIGHT # Now self.image is a string instead of a surface.
游戏开始时加载图像，然后在游戏中重新使用它们。
# Load the images in the global scope and use the convert
# or convert_alpha methods afterwards to improve the performance.
CAR_IMAGE_RIGHT = pygame.image.load("blue-car-hi.png").convert_alpha()
CAR_IMAGE_LEFT = pygame.image.load("blue-car-hi copy.png").convert_alpha()
