自定义的配对回调

When using the Network Manager with the Network Manager HUD, the NetworkManager.StartMatchmaker method enables matchmaking, and populates the NetworkManager.matchMaker property with a NetworkMatch object. Once this is active, the Network Manager HUD uses it and calls methods on NetworkManager to let you perform simple matchmaking.

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); }
    }
}
