为什么自变量在播放器类中不更新

我当时正在使用python进行游戏，我想添加一个功能，每当按下某个键时，就会根据该键旋转玩家图像，但该self.rotation变量永远不会更新

播放器类代码：

import pygame
from physics import Movement

class Player():
    def __init__(self, x, y, width, height, skin):
        self.x = x
        self.y = y
        self.rotation = 0
        self.width = width
        self.height = height
        self.rect = (x, y, width, height)
        self.speed = 3
        self.skin = skin

    def draw(self, win, skin):
        self.rotation = Movement.rotate(self, self.rotation)
        print(self.rotation)
        player = pygame.transform.rotate(skin.convert_alpha(), self.rotation)
        win.blit(player, self.rect)

    def move(self):
        keys = pygame.key.get_pressed()

        if keys[pygame.K_LEFT] or keys[pygame.K_a]:
            self.x -= self.speed

        if keys[pygame.K_RIGHT] or keys[pygame.K_d]:
            self.x += self.speed

        if keys[pygame.K_UP] or keys[pygame.K_w]:
            self.y -= self.speed

        if keys[pygame.K_DOWN] or keys[pygame.K_s]:
            self.y += self.speed

        self.update()

    def update(self):
        self.rect = (self.x, self.y, self.width, self.height)

物理类代码：

import pygame

class Movement():

    def rotate(self, rotation):
        self.rotation = rotation
        keys = pygame.key.get_pressed()

        if keys[pygame.K_RIGHT] or keys[pygame.K_d]:
            if self.rotation < 90 and self.rotation > 0:
                self.rotation += 5

        if keys[pygame.K_DOWN] or keys[pygame.K_s]:
            if self.rotation < 180 and self.rotation > 90:
                self.rotation += 5

        if keys[pygame.K_LEFT] or keys[pygame.K_a]:
            if self.rotation < 270 and self.rotation > 180:
                self.rotation += 5

        if keys[pygame.K_UP] or keys[pygame.K_w]:
            if self.rotation < 360 and self.rotation > 270:
                self.rotation += 5

        return self.rotation

游戏代码：

import pygame
from Network import Network

pygame.font.init()
pygame.init()

width = 700
height = 600
fps = 60
current_id = 0
img = pygame.image.load('game_background.png')
win = pygame.display.set_mode((width, height))
pygame.display.set_caption("Astro party")
info_font = pygame.font.SysFont("Verdana", 26)

player_list = {}
player_count = 0
loaded_skins = {}

n = Network()
name = 'Player'
NAME_FONT = pygame.font.SysFont("comicsans", 24)

def redrawWindow(win, players, id):
    global player_count
    win.blit(img.convert(), (0, 0))

    for player in players:
        p = players[player]
        if player_count < len(players):
            skin = pygame.image.load(p['skin'])
            loaded_skins[player] = skin
        p['player'].draw(win, loaded_skins[player])
        text = NAME_FONT.render(p["name"], 1, (0,0,0))
        win.blit(text, (p['player'].x - text.get_width()/2, p['player'].y - text.get_height()/2))
    player_count = len(players)


def main(name):
    global win, width, height
    run = True
    n = Network()
    clock = pygame.time.Clock()
    current_id = n.connect(name)
    player_list = n.send("get")

    while run:
        clock.tick(fps)

        player_list = n.send("get")

        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                run = False
                pygame.quit()

        player_list[current_id]['player'].move()
        data = player_list
        n.send(data, pick=True)

        redrawWindow(win, player_list, current_id)
        pygame.display.update()

    n.disconnect()
    pygame.quit()
    quit()

main(name)

因此，我试图在玩家单击特定键时批准玩家图像，并且尝试打印self.rotation，但它从未更新。
