Unity 5.3 Api in Unity 5.4 Network Match Example script (Unity Docs Out-Of-Date)

Unity Engine

Hi,
I believe I found an out-of-date example in the unity docs, as I am fairly beginner-ish to unity I have been looking for basic matchmaking code which i could adapt. I found the example here and I have since copied it into a script to try get it working but I am getting errors which I believe are due to CreateMatchRequest() being out-of-date (I’m sure there is some better code term). Hence I have tried to look it up and have found nothing in the unity 5.4 docs but I did find it in the unity 5.3 docs (here). So I believe the unity example in the NetworkMatch class documentation is out-of-date.

  • How can I fix this script so it work in 5.4?
  • Should I report this to unity?
  • Simply what do you think about this?

Thanks this allowed me to adapt the script as below -

Original Script (5.3)

using UnityEngine;
using UnityEngine.Networking;
using UnityEngine.Networking.Match;
using UnityEngine.Networking.Types;
using System.Collections;

public class SimpleMatchMaker : MonoBehaviour
{
    void Start()
    {
        NetworkManager.singleton.StartMatchMaker();
    }

    //call this method to request a match to be created on the server
    public void CreateInternetMatch(string matchName)
    {
        CreateMatchRequest create = new CreateMatchRequest();
        create.name = matchName;
        create.size = 4;
        create.advertise = true;
        create.password = "";

        NetworkManager.singleton.matchMaker.CreateMatch(create, OnInternetMatchCreate);
    }

    //this method is called when your request for creating a match is returned
    private void OnInternetMatchCreate(CreateMatchResponse matchResponse)
    {
        if (matchResponse != null && matchResponse.success)
        {
            //Debug.Log("Create match succeeded");

            MatchInfo hostInfo = new MatchInfo(matchResponse);
            NetworkServer.Listen(hostInfo, 9000);

            NetworkManager.singleton.StartHost(hostInfo);
        }
        else
        {
            Debug.LogError("Create match failed");
        }
    }

    //call this method to find a match through the matchmaker
    public void FindInternetMatch(string matchName)
    {
        NetworkManager.singleton.matchMaker.ListMatches(0, 20, matchName, OnInternetMatchList);
    }

    //this method is called when a list of matches is returned
    private void OnInternetMatchList(ListMatchResponse matchListResponse)
    {
        if (matchListResponse.success)
        {
            if (matchListResponse.matches.Count != 0)
            {
                //Debug.Log("A list of matches was returned");

                //join the last server (just in case there are two...)
                NetworkManager.singleton.matchMaker.JoinMatch(matchListResponse.matches[matchListResponse.matches.Count - 1].networkId, "", OnJoinInternetMatch);
            }
            else
            {
                Debug.Log("No matches in requested room!");
            }
        }
        else
        {
            Debug.LogError("Couldn't connect to match maker");
        }
    }

    //this method is called when your request to join a match is returned
    private void OnJoinInternetMatch(JoinMatchResponse matchJoin)
    {
        if (matchJoin.success)
        {
            //Debug.Log("Able to join a match");


            MatchInfo hostInfo = new MatchInfo(matchJoin);
            NetworkManager.singleton.StartClient(hostInfo);
        }
        else
        {
            Debug.LogError("Join match failed");
        }
    }
}
