我一直试图在使用中围绕其中心旋转图像,pygame.transform.rotate()但它不起作用.特别是挂起的部分是rot_image = rot_image.subsurface(rot_rect).copy().我得到了例外:

ValueError: subsurface rectangle outside surface area

以下是用于旋转图像的代码:

def rot_center(image, angle):
    """rotate an image while keeping its center and size"""
    orig_rect = image.get_rect()
    rot_image = pygame.transform.rotate(image, angle)
    rot_rect = orig_rect.copy()
    rot_rect.center = rot_image.get_rect().center
    rot_image = rot_image.subsurface(rot_rect).copy()
    return rot_image
