Python Pygame在曲面内旋转矩形

我在跟踪两个矩形时遇到了问题，在旋转曲面后，我将它们点到曲面上。 有三个矩形绘制在表面上，代表玩家。按下左键和右键时，所有矩形都会围绕中心点正确旋转。 按下空格键时，“灯光”应打开和关闭，但它们始终在曲面底部重新绘制。 你能告诉我我做错了什么吗

按下键时不要旋转播放器表面，而是将属性

angle

添加到类

player

，该属性存储表面的当前角度。
按下

K_RIGHT

或

K_LEFT

键时，更改

角度

职业玩家（pygame.sprite.sprite）：
高度=48
宽度=48
颜色=（30144255）
定义初始化（自）：
超级（玩家，自我）。\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu（）
# [...]
自转角=0
def更新（自我更新，按键）：
如果按键==pygame.K_RIGHT：
自转角=（自转角-90）%360
如果按下键==pygame.K_左键：
自转角=（自转角+90）%360
# [...] 

这将导致原始曲面永远不会更改，而更改“灯光”将始终有效

创建一个旋转曲面，该曲面由
Player.angle
和
blit
旋转曲面旋转：

rotSurf=pygame.transform.rotate（Player.surf，Player.angle）
screen.blit（rotSurf，Player.rect）

按下键时不要旋转播放器表面，而是向类
