我收到以下错误。 TypeError：参数1必须是pygame.Surface，而不是str
我一直在研究如何格式化图像，似乎没有任何错误。无论如何，这是我的代码：

顺便说一句，这些图片显然不会为你加载，所以如果你想运行它，只需获取任何jpeg图像并命名为＆＃34; blue-car-hi.png＆＃34;或其他名称，以显示图像。
答案 0 :(得分：1)
您在self.image方法中将汽车的CAR_IMAGE_RIGHT设置为move_car_right，但它不是pygame.Surface的字符串。 move_car_left有同样的问题。
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.
在游戏开始时加载您的图片并在游戏中重复使用。
# 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()
