扭曲属性错误

Question

这个问题已经给了我为什么会这样现在发生错误，我想知道如何解决这个问题。

这是 main.py 的代码

from twisted.internet import reactor
import pygame

from networking import run, construct_factory

class GameEngine(object):
    def __init__(self, client):
        pygame.init()
        self.screen = pygame.display.set_mode((640, 400))
        self.FPS = 60
        self.client = client.connectedProtocol
        reactor.callWhenRunning(self.grab_all_sprites)

    def grab_all_sprites(self):
        with open('sprites.txt') as sprites:
            for sprite in sprites:
                sprite_file = self.client.download_sprite(sprite)
                with open(r'resources\%s.png' % sprite, 'wb') as out:
                    out.write(sprite_file)


    def spin(self):
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                reactor.stop()

            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_SPACE:
                    print "spacebar!"

        #update the player
        pygame.display.flip()
        reactor.callLater((1/self.FPS), self.spin)

if __name__ in '__main__':
    client = construct_factory()    
    game = GameEngine(client)
    run(game, client)

这里是networking.py 的代码

from twisted.internet import reactor
from twisted.internet.protocol import ClientFactory
from twisted.protocols import amp
import sys

from ampcommands import TransferSprite

class GameClient(amp.AMP):
    def download_sprite(self, sprite):
        self.callRemote(TransferSprite, sprite)

class GameClientFactory(ClientFactory):
    protocol = GameClient

    def buildProtocol(self, address):
        proto = ClientFactory.buildProtocol(self, address)
        self.connectedProtocol = proto
        return proto

def construct_factory():
    return GameClientFactory()

def run(game, factory, verbose=True):

    if verbose:
        from twisted.python import log
        log.startLogging(sys.stdout)

    reactor.connectTCP("localhost", 1234, factory)
    reactor.callWhenRunning(game.spin)
    reactor.run()

我完全不知道如何在连接建立后调用 game.spin 以便 GameClientFactory .connectedProtocol。我感到困惑和疲倦，有人能找到更好的方法吗？

这看起来就像是你的问题就是你的答案。删除现有的 GameEngine 实例化代码，并将 GameClientFactory 更改为具有如下所示的 buildProtocol：

def buildProtocol(self, address):
    proto = ClientFactory.buildProtocol(self, address)
    GameEngine(proto).spin()
    return proto

将 GameEngine.__init__ 更改为也只需接受协议，因为将其传递给它比将其作为另一个对象的属性然后传递另一个对象更容易。
