Question: How can you set up matchmaking using AWS GameLift?


AWS GameLift is a dedicated game server hosting solution that deploys, operates, and scales cloud servers for multiplayer games. One of its features is FlexMatch, a customizable matchmaking service. Here's how you can set it up:

  1. Create a Matchmaker - Using the Amazon GameLift console, create a new FlexMatch matchmaker. You'll need to specify rulesets for your matchmaker.

  2. Define Matchmaking Rule Sets - Matchmaking rules define the team size, player skill level, and latency policy for the matches. You specify these rules in a JSON format when creating or updating your matchmaker.

  3. Configure Regions - Under the regions tab, specify which AWS regions you want your matchmaker to consider when placing players into games.

  4. Integrate with Your Game - Your game client must make requests to FlexMatch through the GameLift SDK. The SDK provides functions for starting matchmaking, and for handling matchmaking events such as accepting or rejecting proposed matches.

Here is a code snippet showing how you could start matchmaking for a player:

import boto3 client = boto3.client('gamelift') response = client.start_matchmaking( ConfigurationName='YourMatchmakerName', Players=[ { 'PlayerId': 'player1', 'PlayerAttributes': { 'skill': { 'N': '23', }, 'latencyInMs': { 'S': '34', }, }, 'LatencyInMs': { 'us-east-1': 100, } }, ] )

The start_matchmaking function initiates a matchmaking attempt. The ConfigurationName specifies which matchmaker configuration to use, and the Players list contains the players for whom we are seeking matches.

Please note that this is a very basic example of what you can do with AWS GameLift and FlexMatch. Depending on your game's needs, you may need to use more advanced features like backfilling for games in progress, or customizing your matchmaker to handle different types of game modes.
