使用坐标的Python Pandas3D渲染

Question

我遇到了一个错误，我试图使用字符的坐标来呈现字符，然后使用代码reparentTo（render），但是我得到了以下错误：“TypeError:必须是string或buffer，而不是None”。在

服务器代码：

import socket

import pickle
import select
def broadcast(sock, message):

    for socket in CONNECTION:
        if socket != server_socket and socket != sock :

            except :
                # broken socket connection may be, chat client pressed ctrl+c for example
                socket.close()
                CONNECTION.remove(socket)




HOST = ""
PORT = 8303

RECV_BUFFER = 4096 
maxclients = 5

print "Online Server started on port " + str(PORT)  
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_socket.bind(('',PORT))
server_socket.listen(maxclients)
CONNECTION.append(server_socket)
