旋转Rect对象Pygame

Question

我写了一些代码，允许汽车的图像指向并移向鼠标光标。我设法使所有的三角函数都能正常工作，程序也可以运行。 （即使它有点笨拙）但是如果我用矩形替换图像，我将如何旋转它？

import sys, pygame, math
from pygame.locals import *
pygame.init()

SCREEN = pygame.display.set_mode((800, 600))
CrossHair = pygame.image.load('Crosshair.png').convert_alpha()
image = pygame.image.load('Car.png').convert_alpha()

pygame.display.set_caption('Car')
pygame.display.set_icon(image)
CLOCK = pygame.time.Clock()
pygame.mouse.set_visible(False)

def Quit():
    '''Shuts down the game if it's closed'''
    for event in pygame.event.get():
        if event.type == QUIT:
            print('Quit the game...')
            pygame.quit()
            sys.exit()
        if event.type == KEYDOWN:
            if event.key == K_ESCAPE:
                print('Quit the game...')
                pygame.quit()
                sys.exit()

carX, carY = 400, 300
angle = 0
speed = 0

while True:
Quit()
    SCREEN.fill((225, 255, 255))

    pos      = pygame.mouse.get_pos()
    angle    = 360 - math.atan2(pos[1] - carY, pos[0] - carX) * 180 / math.pi
    rotimage = pygame.transform.rotate(image, angle)
    rect     = rotimage.get_rect(center = (carX, carY))

    if pygame.mouse.get_pressed()[0]:
        speed += 1
    if pygame.mouse.get_pressed()[2]:
        speed -= 0.2

    speed *= 0.95    
    carX  += speed * math.cos(math.radians(angle))
    carY  -= speed * math.sin(math.radians(angle))

    SCREEN.blit(rotimage, rect)
    SCREEN.blit(CrossHair, (pos))

    pygame.display.update()
    CLOCK.tick(30)
