The Amazon GameLift Plugin for Unity contains libraries and native UI that makes it easier to access GameLift resources and integrate GameLift into your Unity game. You can use the GameLift Unity Plugin to access GameLift APIs and deploy AWS CloudFormation templates for common gaming scenarios. Auth Only, this scenario creates a game backend service that performs only player authentication and no game server capability. It creates a Cognito user pool to store player authentication information, as well as an API gateway REST endpoint backed up AWS Lambda handlers to start a game and view game connection information. The Lambda handler always returns a 501 Error (Unimplemented). Single-Region Fleet, this scenario creates a game backend service with a single GameLift fleet. After player authenticates and starts a game (with a POST request to /start_game), a AWS Lambda handler searches for an existing viable game session with an open player slot on the fleet.
