How to Rotate an Image Around Its Center in Pygame?

How do I rotate an image around its center using Pygame?

You can rotate an image around its center using pygame.transform.rotate() function. However, the rotated image will be larger than the original image, and the center of the rotated image will not be the same as the center of the original image.

To solve this problem, you need to calculate the offset between the center of the original image and the center of the rotated image. You can then use this offset to move the rotated image so that its center is in the same position as the center of the original image.

Here is an example code that shows how to rotate an image around its center:

def rotate_image(image, angle):
  """Rotates an image around its center.

  Args:
    image: The image to be rotated.
    angle: The angle of rotation in degrees.

  Returns:
    The rotated image.
  """

  # Calculate the offset between the center of the original image and the center of the rotated image.
  offset = (image.get_width() / 2, image.get_height() / 2)

  # Rotate the image around its center.
  rotated_image = pygame.transform.rotate(image, angle)

  # Move the rotated image so that its center is in the same position as the center of the original image.
  rotated_image = rotated_image.subsurface(pygame.Rect(-offset, -offset, image.get_width(), image.get_height()))

  # Return the rotated image.
  return rotated_image
