python 游戏网络库

Python 游戏网络库是开发游戏网络服务真个强大工具。可使用它创建游戏服务器，实现真实时间多人游戏，使游戏更加有趣。

Python 游戏网络库具有众多优点，例如：

• 易于学习和使用
• 强大的网络支持，可以处理大范围并发连接
• 稳定性高，具有完善的毛病处理机制
• 可扩大和定制性强，可以根据需求编写自定义的协议和处理函数

下面是一个简单的 Python 游戏网络库实例。

import socket
import select
HOST = '10.0.0.1'
PORT = 8877
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
server_socket.bind((HOST, PORT))
server_socket.listen(5)
sockets_list = [server_socket]
clients = {}
print(f'Listening for connections on {HOST}:{PORT}...')
def receive_message(client_socket):
try:
message_header = client_socket.recv(1024)
if not len(message_header):
return False
message_length = int(message_header.decode('utf⑻'))
return {'header': message_header, 'data': client_socket.recv(message_length)}
except:
return False
while True:
read_sockets, _, exception_sockets = select.select(sockets_list, [], sockets_list)
for notified_socket in read_sockets:
if notified_socket == server_socket:
client_socket, client_address = server_socket.accept()
user = receive_message(client_socket)
if user is False:
continue
sockets_list.append(client_socket)
clients[client_socket] = user
print(f'Accepted new connection from {client_address[0]}:{client_address[1]}, username: {user["data"].decode("utf⑻")}')
else:
message = receive_message(notified_socket)
if message is False:
print(f'Closed connection from {clients[notified_socket]["data"].decode("utf⑻")}')
sockets_list.remove(notified_socket)
del clients[notified_socket]
continue
user = clients[notified_socket]
print(f'Received message from {user["data"].decode("utf⑻")}: {message["data"].decode("utf⑻")}')
for client_socket in clients:
if client_socket != notified_socket:
client_socket.send(user['header'] + user['data'] + message['header'] + message['data'])
for notified_socket in exception_sockets:
sockets_list.remove(notified_socket)
del clients[notified_socket]

在这个例子中，我们使用了 select() 函数来监听多个套接字，并用一个while循环来不断接受和发送消息。

Python 游戏网络库是游戏开发中非常重要的工具，它可以简化网络编程，下降开发难度，提高开发效力。
