⁠Simple Game Server (Go)

A very simple game server designed to demonstrate and test running a game server on the Unity Multiplay platform⁠.

The container image release is ready for you to upload to Multiplay to try out the service without writing a single line of code!

The capabilities of this sample are as follows:

• Handling of the Multiplay allocation lifecycle⁠
  • When allocated, the sample starts a TCP server on the port defined in the server.json file
  • When de-allocated, this TCP server is stopped
• Dynamic server query results
  • Data such as number of players, map name, etc. are handled appropriately
  • sqp and a2s query protocols supported over the query port defined in the server.json file
• Backfill allocation keep alive
  • If "enableBackfill"="true" is set on the server.json then the server will support keeping alive a backfill ticket in the matchmaker
  • If you are not using the production matchmaker gateway URL (https://matchmaker.services.api.unity.com), then you can change this location by setting the matchmakerUrl parameter in your build configuration settings⁠
    • e.g. "matchmakerUrl": "https://matchmaker-stg.services.api.unity.com"
  • Please see the Matchmaker docs on configuring backfill⁠ for more information on backfill
• Client simulation
  • A game client can be simulated by opening a TCP connection once the server is allocated
    • The server should be allocated first by invoking the server allocations API⁠
    • A TCP connection can be opened with a netcat command: nc <ip> <port>. Once the connection is opened, this connection represents a player - as such, the 'Concurrent Users' count will be updated in the dashboard
