In this video I'll explain how to upload your multiplayer game build to Unity Gaming Services (UGS) Multiplay, which will act as a scalable dedicated hosting platform with minimal setup. Next, we'll discuss Matchmaker, a way to easily connect players and organize a match.

Before uploading to UGS Matchplay, we need to create a Dedicated Linux Server build of our game in Unity. To do this, we create a script to read the command line arguments passed to the game and determine if the build is the server. It is also recommended to set the target frame rate and disable v-sync.

In UGS we will then create a build, a build configuration with our starting parameters, a fleet that will determine where our server will run, and then test it with a test assignment. We also use Matchmaker within our project. Then back to Unity, we write some basic code to connect our game to UnityGamingServices via the IP address passed in the port, and then find a matchmaker assignment that spins up a server. We also enable replenishment to support players who join the match after it has started. On the client side, we write a separate script where the client logs in anonymously, enables UnityGamingServices, and then attempts to fill out their matchmaking ticket to be assigned to the match. At the end of the video we also fix some bugs that become apparent when hosting the game on the UGS dedicated server platform.
