create_game_session#

GameLift.Client.create_game_session(**kwargs)#

Creates a multiplayer game session for players in a specific fleet location. This operation prompts an available server process to start a game session and retrieves connection information for the new game session. As an alternative, consider using the Amazon GameLift game session placement feature with StartGameSessionPlacement , which uses the FleetIQ algorithm and queues to optimize the placement process.

When creating a game session, you specify exactly where you want to place it and provide a set of game session configuration settings. The target fleet must be in ACTIVE status.

You can use this operation in the following ways:

  • To create a game session on an instance in a fleet’s home Region, provide a fleet or alias ID along with your game session configuration.

  • To create a game session on an instance in a fleet’s remote location, provide a fleet or alias ID and a location name, along with your game session configuration.

  • To create a game session on an instance in an Anywhere fleet, specify the fleet’s custom location.

If successful, Amazon GameLift initiates a workflow to start a new game session and returns a GameSession object containing the game session configuration and status. When the game session status is ACTIVE, it is updated with connection information and you can create player sessions for the game session. By default, newly created game sessions are open to new players. You can restrict new player access by using UpdateGameSession to change the game session’s player session creation policy.

Amazon GameLift retains logs for active for 14 days. To access the logs, call GetGameSessionLogUrl to download the log files.

Available in Amazon GameLift Local.

Request Syntax

response = client.create_game_session(
    FleetId='string',
    AliasId='string',
    MaximumPlayerSessionCount=123,
    Name='string',
    GameProperties=[
        {
            'Key': 'string',
            'Value': 'string'
        },
    ],
    CreatorId='string',
    GameSessionId='string',
    IdempotencyToken='string',
    GameSessionData='string',
    Location='string'
)
Parameters:

  • FleetId (string) – A unique identifier for the fleet to create a game session in. You can use either the fleet ID or ARN value. Each request must reference either a fleet ID or alias ID, but not both.

  • AliasId (string) – A unique identifier for the alias associated with the fleet to create a game session in. You can use either the alias ID or ARN value. Each request must reference either a fleet ID or alias ID, but not both.

  • MaximumPlayerSessionCount (integer) –

    [REQUIRED]

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

  • Name (string) – A descriptive label that is associated with a game session. Session names do not need to be unique.

  • GameProperties (list) –

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

    • (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) – [REQUIRED]

        The game property identifier.

      • Value (string) – [REQUIRED]

        The game property value.

  • CreatorId (string) –

    A unique identifier for a player or entity creating the game session.

    If you add a resource creation limit policy to a fleet, the CreateGameSession operation requires a CreatorId. Amazon GameLift limits the number of game session creation requests with the same CreatorId in a specified time period.

    If you your fleet doesn’t have a resource creation limit policy and you provide a CreatorId in your CreateGameSession requests, Amazon GameLift limits requests to one request per CreatorId per second.

    To not limit CreateGameSession requests with the same CreatorId, don’t provide a CreatorId in your CreateGameSession request.

  • GameSessionId (string) –

    This parameter is deprecated. Use IdempotencyToken instead.

    Custom string that uniquely identifies a request for a new game session. Maximum token length is 48 characters. If provided, this string is included in the new game session’s ID.

  • IdempotencyToken (string) – Custom string that uniquely identifies the new game session request. This is useful for ensuring that game session requests with the same idempotency token are processed only once. Subsequent requests with the same string return the original GameSession object, with an updated status. Maximum token length is 48 characters. If provided, this string is included in the new game session’s ID. A game session ARN has the following format: arn:aws:gamelift:<region>::gamesession/<fleet ID>/<custom ID string or idempotency token>. Idempotency tokens remain in use for 30 days after a game session has ended; game session objects are retained for this time period and then deleted.

  • GameSessionData (string) – A set of custom game session properties, formatted as a single string value. This data is passed to a game server process with a request to start a new game session. For more information, see Start a game session.

  • Location (string) – A fleet’s remote location to place the new game session in. If this parameter is not set, the new game session is placed in the fleet’s home Region. Specify a remote location with an Amazon Web Services Region code such as us-west-2. When using an Anywhere fleet, this parameter is required and must be set to the Anywhere fleet’s custom location.
