NetworkManager网络通讯_NetworkManager（二）
本文主要来实现一下自定UI（实现HUD的功能），并对Network Manger进行深入的讲解。
1）自定义manager
创建脚本CustomerUnetManger，并继承自NetworkManger，并对相关虚函数进行重载，并简单写了几个外部调用方法。完整脚本在文末，部分截图如下：
其中LogInfo为debug用，完整脚本在文末
2）UI脚本CustomerUnetMainMenu
编写脚本，实现自定义新建Server client 以及host，再次着重说一下原NetworkMangerHUD脚本中的第四个方法，即NetworkManger中的matchmaker。matchmaker通过unity提供的网络服务，建立游戏，然后通过你自己生成的exe就可以获取到建立的游戏列表，然后可以加入游戏：
首先开启matchmaker
/// <summary> /// UI调用,MatchMaker /// </summary> public void StartMatchMaker_() { if (!IsClientConnected() && !NetworkServer.active && matchMaker == null) { StartMatchMaker(); matchMode = true; } }
然后建立游戏
/// <summary> /// UI调用，创建比赛 /// </summary> public void CreateMatch_() { if (matchMaker != null) { matchMaker.CreateMatch("LLMatch", 3, true, "", "", "", 0, 0, OnMatchCreate); } }
获取游戏列表（获取列表并UI显示时需要脚本match Button）
matchMaker.ListMatches(0, 5, "", true, 0, 0, OnMatchList);
加入游戏
/// <summary> /// 加入指定的比赛 /// 对于建立比赛的player，本身已经在游戏中，所以不能再次加入（已经生成host） /// 对于建立比赛的player，在加入其他游戏时先取消比赛（DestroyMatch） /// 对于加入比赛的player，只能加入一次，不能重复加入（已经生成client） /// 对于加入比赛的Player，在重复加入或者加入其他游戏之前先断开连接（DropConnection） /// 本程序为demo，上述问题不做处理 /// </summary> /// <param name="jointMatch"></param> public void JoinMatch(MatchInfoSnapshot jointMatch) { if (matchMaker == null) StartMatchMaker(); matchMaker.JoinMatch(jointMatch.networkId, "", "", "", 0, 0, OnMatchJoined);//调用此方法时生成client }
3）此部分到此基本结束没有太大问题，一些注意事项已经在代码中注释，至于如何退出比赛等会再下一篇LobbyManager中进行解释，下边时此工程的所有脚本文件。再次说明一下，玩家预制体等均采用上一篇。此工程为demo，所以UI简陋，可能会有不友好的操作或者逻辑bug
