我有一个小游戏,有一个小客户端,游戏从服务器接收数据。客户端在一个模块中,而游戏在另一个模块中。问题是客户端从服务器接收数据,但是为了在游戏中执行操作,客户端需要访问游戏的方法(类MyGame),使用这样的代码我得到一个错误:
模块客户端:
class MyClient:
#receives data from the server
#It is a task, always listening
def readerConnection:
#if a data arrives from the server...
if newData:
#call dataOnScreen of class MyGame
...dataOnScreen()
模块游戏:
from client import MyClient
class MyGame:
def _init_(self, client):
#begin to receive data from the server
self.c = client
#print data received from the server on screen
def dataOnScreen(self):
............
#the game begins
MyGame(MyClient())
当然,发生错误是因为在MyClient类中没有定义dataOnScreen方法。 如果我做以下事情,事情就好了(把客户写入游戏):
class MyGame:
def _init_(self):
.........
#receives data from the server
#It is a task, always listening
def readerConnection:
#if a data arrives from the server...
if newData:
#call dataOnScreen
self.dataOnScreen()
#print data received from the server on screen
def dataOnScreen(self):
............
#the game begins
MyGame()
但这不是我想要的。我想要的是让游戏和客户在不同的班级。
感谢您的帮助。

也许您可以执行诸如将函数或MyGame对象传递到客户端之类的操作,因此它知道在接收数据时该怎么做。
像
这样的东西class MyGame:
def _init_(self, client):
#begin to receive data from the server
self.c = client
client.game = self
class MyClient:
#receives data from the server
#It is a task, always listening
def readerConnection:
#if a data arrives from the server...
if newData:
#call dataOnScreen of class MyGame
self.game.dataOnScreen()
有点像客户端的上下文或传入函数时的回调。
