Question

我试图按下按钮使图像旋转。当我点击屏幕时图像会旋转，但它会每隔五度继续复制一次，并且在运行一段时间后它也会崩溃。我确定有更好的方法来做到这一点，但我只是不知道它是什么。这是我的代码

while True:
        for event in pygame.event.get():
            '''Quit Button'''
            if event.type == pygame.QUIT:
                pygame.quit()
            elif event.type == pygame.MOUSEBUTTONUP and event.button == 1:
                screen.blit(target, targetpos)

            elif event.type == pygame.MOUSEBUTTONDOWN and event.button == 1:
                # # if mouse is pressed get position of cursor ##
                screen.blit(target1, target1pos)
            degree = 0
            while True:
                image_surf = pygame.image.load('image.png')
                image_surf = pygame.transform.scale(image_surf, (810, 810))
                image_surfpos = image_surf.get_rect()
                blittedRect = screen.blit(image_surf, image_surfpos)
                'Get center of surf for later'
                oldCenter = blittedRect.center
                'rotate surf by amount of degrees'
                rotatedSurf = pygame.transform.rotate(image_surf, degree)
                'Get the rect of the rotated surf and set its center to the old center'
                rotRect = rotatedSurf.get_rect()
                rotRect.center = oldCenter
                'Change the degree of rotation'

                screen.blit(rotatedSurf, rotRect)
                degree += 5
                if degree > 360:
                    degree = 0


                'Show the screen Surface'
                pygame.display.flip()

                'Wait 60 ms for loop to restart'
                pygame.time.wait(60)

看起来你有一个双while循环，它不会让你编写事件处理代码。也不要在每一帧真正的fps杀手

的情况下加载图像
