Integration using Unity’s High-Level API

To integrate Unity Multiplayer Services using the Networking High-Level API, you must use the NetworkMatch class directly in your scripts. To use it, you have to call the functions in NetworkMatch manually and handle the callbacks yourself.

Below is an example of how you can create a match, list matches, and join a match using only the NetworkMatch, NetworkServer and NetworkClient classes.

This script sets up the matchmaker to point to the public Unity matchmaker server. It calls the NetworkMatch functions for creating, listing, and joining matches:

• CreateMatch to create a match
• JoinMatch to join a match
• ListMatches for listing matches registered on the matchmaker server

Internally, NetworkMatch uses web services to establish a match, and the given callback function is invoked when the process is complete, such as OnMatchCreate for match creation.

public class HostGame : MonoBehaviour
{
    List<MatchInfoSnapshot> matchList = new List<MatchInfoSnapshot>();
    bool matchCreated;
    NetworkMatch networkMatch;

    void Awake()
    {
        networkMatch = gameObject.AddComponent<NetworkMatch>();
    }

    void OnGUI()
    {
        // You would normally not join a match you created yourself but this is possible here for demonstration purposes.
        if (GUILayout.Button("Create Room"))
        {
            string matchName = "room";
            uint matchSize = 4;
            bool matchAdvertise = true;
            string matchPassword = "";

            networkMatch.CreateMatch(matchName, matchSize, matchAdvertise, matchPassword, "", "", 0, 0, OnMatchCreate);
        }

        if (GUILayout.Button("List rooms"))
        {
            networkMatch.ListMatches(0, 20, "", true, 0, 0, OnMatchList);
        }

            {
