Java中的多人游戏。将客户端（玩家）连接到其他客户端创建的游戏
摘要: 服务器可以将它们发送给所有客户端（您不需要点对点网络就可以让客户端B向客户端A发送一些数据），因此客户端A能够在客户端B的位置绘制字符图块，我在这篇文章的结尾添加了一个Java示例;Socket socket = listener.accept();try;writerChannel.flush();System.out.println(line)listener.close()
如何解决Java中的多人游戏。将客户端（玩家）连接到其他客户端创建的游戏？
另一个客户端由于其防火墙而无法连接到客户端A。
您可以创建两种主要的网络：
服务器客户端
点对点
但是客户端可以将一些数据保存到服务器，服务器可以将它们发送给所有客户端（您不需要点对点网络就可以让客户端B向客户端A发送一些数据）。
示例：客户端B将其地图位置发送到服务器，服务器将数据发送给所有客户端，因此客户端A能够在客户端B的位置绘制字符图块。
要将两台PC连接在一起，您需要将端口从服务器的调制解调器转发到用作服务器的PC，然后从用作服务器的PC的防火墙打开该端口。
您还可以在这里看看如何使用python创建一个多人游戏，我举了一个示例，其中客户端可以将它们与IRC连接在一起，并可以玩井字游戏（因此您不必管理服务器） ）。我在这篇文章的结尾添加了一个Java示例。

我无法为您提供对等网络的示例，因为我从未这样做过。这确实很困难，您必须在互联网上进行大量研究。

您需要一个多线程服务器来处理许多不同的连接。
提示-我已经回答了一些类似的问题。 即使编程语言有时有所不同，我也会为您提供链接，但逻辑总是相同的，因此可以为您提供帮助：

解决方法
我正在开发多人游戏，无法找出如何将其他客户端连接到所创建的游戏。我的意思是客户端A创建与服务器的套接字连接，其他客户端（A，B
…）如何连接到客户端A？有人可以帮我吗？
PS我是网络编程的新手，因此，如果您可以举一些例子，我将不胜感激。
