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 scriptsA piece of code that allows you to create your own Components, trigger game events, modify Component properties over time and respond to user input in any way you like.

See in Glossary
. 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:

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.

        networkMatch = gameObject.AddComponent<NetworkMatch>();
