pygame中无法旋转图像

Question

Just getting started in pygame, am trying to do something extremely simple (draw a rotated image).

import pygame
import math
screen = pygame.display.set_mode((1024,768))
helicopter = pygame.image.load('helicopter.png')
screen.blit(pygame.transform.rotate(helicopter, math.pi/2), (100,150))
pygame.display.flip()

However this only draws the unrotated version of the image. How do I fix this?

Answer 1

the rotate method use degrees ( doc ):

import pygame
screen = pygame.display.set_mode((1024,768))
helicopter = pygame.image.load('helicopter.png')
screen.blit(pygame.transform.rotate(helicopter, 90), (100,150))
pygame.display.flip()
