CreateMatchmakingConfiguration

Defines a new matchmaking configuration for use with FlexMatch. A matchmaking configuration sets out guidelines for matching players and getting the matches into games. You can set up multiple matchmaking configurations to handle the scenarios needed for your game. Each matchmaking ticket (StartMatchmaking or StartMatchBackfill) specifies a configuration for the match and provides player attributes to support the configuration being used.

To create a matchmaking configuration, at a minimum you must specify the following: configuration name; a rule set that governs how to evaluate players and find acceptable matches; a game session queue to use when placing a new game session for the match; and the maximum time allowed for a matchmaking attempt.

To track the progress of matchmaking tickets, set up an Amazon Simple Notification Service (SNS) to receive notifications, and provide the topic ARN in the matchmaking configuration. An alternative method, continuously poling ticket status with DescribeMatchmaking, should only be used for games in development with low matchmaking usage.

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

Note

In the following list, the required parameters are described first.

AcceptanceRequired

A flag that determines whether a match that was created with this configuration must be accepted by the matched players. To require acceptance, set to TRUE.

Type: Boolean

Required: Yes

GameSessionQueueArns

Amazon Resource Name (ARN) that is assigned to a GameLift game session queue resource and uniquely identifies it. ARNs are unique across all Regions. These queues are used when placing game sessions for matches that are created with this matchmaking configuration. Queues can be located in any Region.

Type: Array of strings

Length Constraints: Minimum length of 1. Maximum length of 256.

Pattern: [a-zA-Z0-9:/-]+

Required: Yes

Name

A unique identifier for a matchmaking configuration. This name is used to identify the configuration associated with a matchmaking request or ticket.

Type: String

Length Constraints: Maximum length of 128.

Pattern: [a-zA-Z0-9-\.]*

Required: Yes

RequestTimeoutSeconds

The maximum duration, in seconds, that a matchmaking ticket can remain in process before timing out. Requests that fail due to timing out can be resubmitted as needed.

Type: Integer

Valid Range: Minimum value of 1. Maximum value of 43200.

Required: Yes

RuleSetName

A unique identifier for a matchmaking rule set to use with this configuration. You can use either the rule set name or ARN value. A matchmaking configuration can only use rule sets that are defined in the same Region.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 256.

Pattern: [a-zA-Z0-9-\.]*|^arn:.*:matchmakingruleset\/[a-zA-Z0-9-\.]*

Required: Yes

AcceptanceTimeoutSeconds

The length of time (in seconds) to wait for players to accept a proposed match. If any player rejects the match or fails to accept before the timeout, the ticket continues to look for an acceptable match.

Type: Integer

Valid Range: Minimum value of 1. Maximum value of 600.

Required: No

AdditionalPlayerCount

The number of player slots in a match to keep open for future players. For example, assume that the configuration's rule set specifies a match for a single 12-person team. If the additional player count is set to 2, only 10 players are initially selected for the match.

Type: Integer

Valid Range: Minimum value of 0.

Required: No

BackfillMode

The method used to backfill game sessions that are created with this matchmaking configuration. Specify MANUAL when your game manages backfill requests manually or does not use the match backfill feature. Specify AUTOMATIC to have GameLift create a StartMatchBackfill request whenever a game session has one or more open slots. Learn more about manual and automatic backfill in Backfill Existing Games with FlexMatch.

Type: String

Valid Values: AUTOMATIC | MANUAL

Required: No

CustomEventData

Information to be added to all events related to this matchmaking configuration.

A human-readable description of the matchmaking configuration.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 1024.

Required: No

GameProperties

A set of custom properties for a game session, formatted as key-value pairs. These properties are passed to a game server process in the GameSession object with a request to start a new game session (see Start a Game Session). This information is added to the new GameSession object that is created for a successful match.

Type: Array of GameProperty objects

Array Members: Maximum number of 16 items.

Required: No

GameSessionData

A set of custom game session properties, formatted as a single string value. This data is passed to a game server process in the GameSession object with a request to start a new game session (see Start a Game Session). This information is added to the new GameSession object that is created for a successful match.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 4096.

Required: No

NotificationTarget

An SNS topic ARN that is set up to receive matchmaking notifications.

Type: String

Length Constraints: Minimum length of 0. Maximum length of 300.

Pattern: [a-zA-Z0-9:_/-]*

Required: No
