pygame image rotate continuously

We can know by searching that the method of image rotation in pygame is pygame.transform.rotate(), but in actual use, we will find that if we want to continuously rotate an object, simplyUsing this method will cause the image to be distorted and completely lose its original appearance.

After research, it is found that the reason for the image distortion is that after each rotation using the above method, the center point of the image will change, so our solution is to set the rotation center to remain unchanged every time it rotates.The code is as follows:

x = 0y = 0# import original imageimage_raw = pygame.image.load("your image").convert_alpha()# set the center of rotationcore = (x,y)# Set the angle (0~360)angle = 60# rotate the imageimage = pygame.transform.rotate(image_raw, angle)# Draw the image and set the center position, note that the center here must be a tuple tupleself.screen.blit(image, image.get_rect(center=tuple(core)))

If we need to rotate continuously and change the position of the rotation center, just adjust the values ​​of core and angle.Note that the range of angle uses the angle system (0~360)
