how to rotate image in pygame

Comment

# first argument is the original_image
# second one is the angle by how much angle you want you image to be rotated
# third is the zoom amount here it is set to 1 because we don't need to zomm in or out

img_rotated = pygame.transform.rotozoom(original_image,angle,1)

# NOTE: you can use the pygame.transform.rotate but some times rotozoom works better
