describe_game_session_placement#

GameLift.Client.describe_game_session_placement(**kwargs)#

Retrieves information, including current status, about a game session placement request.

To get game session placement details, specify the placement ID.

This operation is not designed to be continually called to track game session status. This practice can cause you to exceed your API limit, which results in errors. Instead, you must configure configure an Amazon Simple Notification Service (SNS) topic to receive notifications from FlexMatch or queues. Continuously polling with DescribeGameSessionPlacement should only be used for games in development with low game session usage.

Response Structure

  • (dict) –

    • GameSessionPlacement (dict) –

      Object that describes the requested game session placement.

      • PlacementId (string) –

        A unique identifier for a game session placement.

      • GameSessionQueueName (string) –

        A descriptive label that is associated with game session queue. Queue names must be unique within each Region.

      • Status (string) –

        Current status of the game session placement request.

        • PENDING – The placement request is in the queue waiting to be processed. Game session properties are not yet final.

        • FULFILLED – A new game session has been successfully placed. Game session properties are now final.

        • CANCELLED – The placement request was canceled.

        • TIMED_OUT – A new game session was not successfully created before the time limit expired. You can resubmit as a new placement request as needed.

        • FAILED – Amazon GameLift is not able to complete the process of placing the game session. Common reasons are the game session terminated before the placement process was completed, or an unexpected internal error.

      • GameProperties (list) –

        A set of key-value pairs that can store custom data in a game session. For example: {"Key": "difficulty", "Value": "novice"}.

        • (dict) –

          This key-value pair can store custom data about a game session. For example, you might use a GameProperty to track a game session’s map, level of difficulty, or remaining time. The difficulty level could be specified like this: {"Key": "difficulty", "Value":"Novice"}.

          You can set game properties when creating a game session. You can also modify game properties of an active game session. When searching for game sessions, you can filter on game property keys and values. You can’t delete game properties from a game session.

          For examples of working with game properties, see Create a game session with properties.

          • Key (string) –

            The game property identifier.

          • Value (string) –

            The game property value.

      • MaximumPlayerSessionCount (integer) –

        The maximum number of players that can be connected simultaneously to the game session.

      • GameSessionName (string) –

        A descriptive label that is associated with a game session. Session names do not need to be unique.

      • GameSessionId (string) –

        A unique identifier for the game session. This value isn’t final until placement status is FULFILLED.

      • GameSessionArn (string) –

        Identifier for the game session created by this placement request. This identifier is unique across all Regions. This value isn’t final until placement status is FULFILLED.

      • GameSessionRegion (string) –

        Name of the Region where the game session created by this placement request is running. This value isn’t final until placement status is FULFILLED.

      • PlayerLatencies (list) –

        A set of values, expressed in milliseconds, that indicates the amount of latency that a player experiences when connected to @aws; Regions.

        • (dict) –

          Regional latency information for a player, used when requesting a new game session. This value indicates the amount of time lag that exists when the player is connected to a fleet in the specified Region. The relative difference between a player’s latency values for multiple Regions are used to determine which fleets are best suited to place a new game session for the player.

          • PlayerId (string) –

            A unique identifier for a player associated with the latency data.

          • RegionIdentifier (string) –

            Name of the Region that is associated with the latency value.

          • LatencyInMilliseconds (float) –

            Amount of time that represents the time lag experienced by the player when connected to the specified Region.

      • StartTime (datetime) –

        Time stamp indicating when this request was placed in the queue. Format is a number expressed in Unix time as milliseconds (for example "1469498468.057").

      • EndTime (datetime) –

        Time stamp indicating when this request was completed, canceled, or timed out.

      • IpAddress (string) –

        The IP address of the game session. To connect to a Amazon GameLift game server, an app needs both the IP address and port number. This value isn’t final until placement status is FULFILLED.

      • DnsName (string) –

        The DNS identifier assigned to the instance that is running the game session. Values have the following format:

        • TLS-enabled fleets: <unique identifier>.<region identifier>.amazongamelift.com.

        • Non-TLS-enabled fleets: ec2-<unique identifier>.compute.amazonaws.com. (See Amazon EC2 Instance IP Addressing.)

        When connecting to a game session that is running on a TLS-enabled fleet, you must use the DNS name, not the IP address.

      • Port (integer) –

        The port number for the game session. To connect to a Amazon GameLift game server, an app needs both the IP address and port number. This value isn’t final until placement status is FULFILLED.

      • PlacedPlayerSessions (list) –

        A collection of information on player sessions created in response to the game session placement request.

This information includes the player ID, provided in the placement request, and a corresponding player session ID.

        • (dict) –

          Information about a player session. This object contains only the player ID and player session ID. To retrieve full details on a player session, call DescribePlayerSessions with the player session ID.

      • MatchmakerData (string) –

        Information on the matchmaking process for this game. Data is in JSON syntax, formatted as a string. It identifies the matchmaking configuration used to create the match, and contains data on all players assigned to the match, including player attributes and team assignments. For more details on matchmaker data, see Match Data.
