在 while 循环中从服务器接收数据显示 window 没有响应
Receiving data from server in while loop Shows window not responding
我正在制作一个初学者在线多人游戏 Tic Tac Toe 游戏，它在本地服务器上运行。我的 code.I 有 2 个问题已将我的游戏文件夹分成 6 个 python 文件：
Client1.py:- 这个文件是输出文件，客户端 have.I 有一些这个文件中的问题。当玩家正在等待其他玩家移动时处于 while 循环中，如果此客户端已播放，它将发送 PLAYED 到服务器，如果服务器正在等待其他玩家移动，它将发送 W 给该客户端，否则它将发送玩家移动 number.While 这个 .py 文件正在等待回复它从服务器获取的消息是 W 然后 window 显示 Not Responding。两个客户端都参考了 Clientsupport.py 和 Network.py。这两个文件仅用于支持客户
import pygame
from Network import network
from clientSupport import GameHelp
n=network()
pt=n.getpos()
g=GameHelp()
g.Display_Start_Up(pt)
if pt==0:
run1=True
run2=False
elif pt==1:
run1 = False
run2 = True
while True:
while run1:
num = None
num=g.Input()
out=n.send(num)
print(out,"hrl")
if out =='Y':
print(num,pt,'hey')
g.Placing(num,pt)
run2=True
break
else:
pass
while run2:
opp=n.send('PLAYED')
print(opp,'loop2')
if opp=='W':
pygame.time.delay(500)
else:
print('here is',opp)
if pt==0:
op=1
elif pt==1:
op=0
g.Placing(opp, op)
print(opp,op,'hello')
run1=True
break
Client2.py:-这个文件是 Client1.py 的精确副本。但这两个文件都是有同样的问题。这是 第二个问题 当两个客户端都连接时，X 和 O 图像仅在加入服务器的第一个客户端上被 blit。对于第二个客户端，它的空白 window 只有板，但输入和其他一切都正常。
Server.py:- 这从另一个文件 Game.py 获取参考。服务器使用此文件来检查谁赢得了什么分数和其他参数。 Pt 服务器中的变量基本上是playertag 发送0 并且1.the 先加入的玩家获得0 并且是X 玩家否则玩家是O 玩家。

pygame.display.update()
Network.py:-关于这个文件没什么好说的，这个文件只连接并向服务器发送消息并工作非常好。
最终调试帮助:- 有 2 个问题:
- 等待对手移动时 Windows 显示无响应
- 总是作为玩家 O 的客户端没有得到图像 blit 认为它接受输入并发送它
到服务器。
A Pygame window 期望它的事件队列总是被处理。典型的 PyGame 程序如下所示：
### Do some initialisation
[...]
### Main Loop
while not exiting:
### handle every event in the queue
for event in pygame.event.get():
if ( event.type == pygame.QUIT ):
exiting = True
elif ( event.type == [ ... ] ):
### Update all the game logic, sprites, network comms, whatever
if ( networkDataArrived( server_socket, server_rx_buffer ) ):
handleNetworkData( server_rx_buffer )
game_sprites.update()
### paint the screen
window.fill( WHITE )
paintGameBoard( window )
game_sprites.draw( window )
### Hopefully do nothing for the rest of the frame-time
clock.tick( FPS )
不正常只是停止超过一秒钟。如果您正在等待套接字数据到达，则需要检查是否有数据到达，如果没有立即继续。如果您正在等待键盘输入，则不能仅调用 input()... 它 破坏 事件模型。
要处理网络通信，您必须进行非阻塞读取。 一种方法 是使用 select.select() function。这允许您在套接字缓冲区 "peek" 查看是否有任何内容到达。如果数据已经到达，您可以读取确切的数量而不会阻塞。否则你就回到你的主循环。请注意，还有其他方法可以做到这一点，但是 select() 在所有操作系统（至少对于套接字）上都可用，并且在大多数编程语言中都可用，因此了解它是一个很好的功能。
请考虑 networkDataArrived() 的准~伪代码:
def networkDataArrived( server_socket, socket_buffer ):
""" Read from the socket, stuffing data into the buffer.
Returns True when a full packet has been read into the buffer """
result = False
socks = [ server_socket ]
input,output,excep = select.select( socks, [], [], 0.01 ) # tiny read-timeout
### has any data arrived?
if ( input.count( server_socket ) > 0 ):
socket_buffer.append( server_socket.recv( MAX_PACKET_SIZE ) )
### do we have a full packet?
if ( len( socket_buffer ) >= MAX_PACKET_SIZE ):
result = True
return result
