Synopsis

Calls the Amazon GameLift Service StartMatchmaking API operation.

Syntax

Start-GMLMatchmaking
-ConfigurationName <String>
-Player <Player[]>
-TicketId <String>
-Force <SwitchParameter>

Description

Uses FlexMatch to create a game match for a group of players based on custom matchmaking rules, and starts a new game for the matched players. Each matchmaking request specifies the type of match to build (team configuration, rules for an acceptable match, etc.). The request also specifies the players to find a match for and where to host the new game session for optimal performance. A matchmaking request might start with a single player or a group of players who want to play together. FlexMatch finds additional players as needed to fill the match. Match type, rules, and the queue used to place a new game session are defined in a MatchmakingConfiguration. For complete information on setting up and using FlexMatch, see the topic Adding FlexMatch to Your Game. To start matchmaking, provide a unique ticket ID, specify a matchmaking configuration, and include the players to be matched. You must also include a set of player attributes relevant for the matchmaking configuration. If successful, a matchmaking ticket is returned with status set to QUEUED. Track the status of the ticket to respond as needed and acquire game session connection information for successfully completed matches. Tracking ticket status -- A couple of options are available for tracking the status of matchmaking requests:
  • Polling -- Call DescribeMatchmaking. This operation returns the full ticket object, including current status and (for completed tickets) game session connection info. We recommend polling no more than once every 10 seconds.
  • Notifications -- Get event notifications for changes in ticket status using Amazon Simple Notification Service (SNS). Notifications are easy to set up (see CreateMatchmakingConfiguration) and typically deliver match status changes faster and more efficiently than polling. We recommend that you use polling to back up to notifications (since delivery is not guaranteed) and call DescribeMatchmaking only when notifications are not received within 30 seconds.
Processing a matchmaking request -- FlexMatch handles a matchmaking request as follows:
  1. Your client code submits a StartMatchmaking request for one or more players and tracks the status of the request ticket.
  2. FlexMatch uses this ticket and others in process to build an acceptable match. When a potential match is identified, all tickets in the proposed match are advanced to the next status.
  3. If the match requires player acceptance (set in the matchmaking configuration), the tickets move into status REQUIRES_ACCEPTANCE. This status triggers your client code to solicit acceptance from all players in every ticket involved in the match, and then call AcceptMatch for each player. If any player rejects or fails to accept the match before a specified timeout, the proposed match is dropped (see AcceptMatch for more details).
  4. Once a match is proposed and accepted, the matchmaking tickets move into status PLACING. FlexMatch locates resources for a new game session using the game session queue (set in the matchmaking configuration) and creates the game session based on the match data.
  5. When the match is successfully placed, the matchmaking tickets move into COMPLETED status. Connection information (including game session endpoint and player session) is added to the matchmaking tickets. Matched players can use the connection information to join the game.
Matchmaking-related operations include:

Parameters

-ConfigurationName <String>
Name of the matchmaking configuration to use for this request. Matchmaking configurations must exist in the same region as this request.
Required?False
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
-Force <SwitchParameter>
This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?False
-Player <Player[]>
Information on each player to be matched. This information must include a player ID, and may contain player attributes and latency data to be used in the matchmaking process. After a successful match, Player objects contain the name of the team the player is assigned to.
Required?False
Position?Named
Accept pipeline input?False
-TicketId <String>
Unique identifier for a matchmaking ticket. Use this identifier to track the matchmaking ticket status and retrieve match results.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required? False
Position? Named
Accept pipeline input? False
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required? False
Position? Named
Accept pipeline input? False
-ProfileLocation <String>

Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)

If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials. Note that the encrypted credential file is not supported on all platforms. It will be skipped when searching for profiles on Windows Nano Server, Mac, and Linux platforms.

If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.

As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.

Required? False
Position? Named
Accept pipeline input? False
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.
Required? False
Position? Named
Accept pipeline input? False
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required? False
Position? Named
Accept pipeline input? False
-SecretKey <String>
The AWS secret key for the user account. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter.
Required? False
Position? Named
Accept pipeline input? False
-SessionToken <String>
The session token if the access and secret keys are temporary session-based credentials.
Required? False
Position? Named
Accept pipeline input? False
-Region <String>
The system name of the AWS region in which the operation should be invoked. For example, us-east-1, eu-west-1 etc.
Required? False
Position? Named
Accept pipeline input? False
-EndpointUrl <String>

The endpoint to make the call against.

Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.

Required? False
Position? Named
Accept pipeline input? False

Inputs

You can pipe a String object to this cmdlet for the ConfigurationName parameter.

Outputs

This cmdlet returns a MatchmakingTicket object. The service call response (type Amazon.GameLift.Model.StartMatchmakingResponse) can also be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.
