自定义的配对回调

将 Network Manager 与 Network Manager HUD 结合使用时，NetworkManager.StartMatchmaker 方法支持进行配对，并使用 NetworkMatch 对象来填充 NetworkManager.matchMaker 属性。在激活此属性后，Network Manager HUD 将使用此属性并调用 NetworkManager 上的方法，让您执行简单配对。

NetworkManager 上有一些虚拟函数，您可以通过从 NetworkManager 派生自己的类来自定义这些虚拟函数。然后，可以自定义新的 NetworkManager 类对 Matchmaker 回调的响应方式。

下面显示了这些回调及其默认实现。如果重写这些回调，有些方法会要求您调用基本实现，否则 Network Manager HUD 的功能将中断。例如，OnMatchCreate 的默认实现（用于启动主机）。

using UnityEngine;
using UnityEngine.Networking;
using UnityEngine.Networking.Match;

public class CustomManager : NetworkManager {

    public override void OnMatchCreate(bool success, string extendedInfo, MatchInfo matchInfo) {
        if (LogFilter.logDebug) { Debug.LogFormat("NetworkManager OnMatchCreate Success:{0}, ExtendedInfo:{1}, matchInfo:{2}", success, extendedInfo, matchInfo); }
        if(success)
            StartHost(matchInfo);
    }

    public override void OnMatchJoined(bool success, string extendedInfo, MatchInfo matchInfo) {
        if (LogFilter.logDebug) { Debug.LogFormat("NetworkManager OnMatchJoined Success:{0}, ExtendedInfo:{1}, matchInfo:{2}", success, extendedInfo, matchInfo); }
        if(success)
            StartClient(matchInfo);
    }

    public override void OnMatchList(bool success, string extendedInfo, List<MatchInfoSnapshot> matchList) {
        if (LogFilter.logDebug) { Debug.LogFormat("NetworkManager OnMatchList Success:{0}, ExtendedInfo:{1}, matchList.Count:{2}", success, extendedInfo, matchList.Count); }
        matches = matchList;
    }

    public override void OnDestroyMatch(bool success, string extendedInfo) {
        if (LogFilter.logDebug) { Debug.LogFormat("NetworkManager OnDestroyMatch Success:{0}, ExtendedInfo:{1}", success, extendedInfo); }
    }

    public override void OnDropConnection(bool success, string extendedInfo) {
        if (LogFilter.logDebug) { Debug.LogFormat("NetworkManager OnDestroyMatch Success:{0}, ExtendedInfo:{1}", success, extendedInfo); }
    }

    public override void OnSetMatchAttributes(bool success, string extendedInfo) {
        if (LogFilter.logDebug) { Debug.LogFormat("NetworkManager OnDestroyMatch Success:{0}, ExtendedInfo:{1}", success, extendedInfo); }
    }
}
