create-game-session

Description

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 GameLift game session placement feature with

with StartGameSessionPlacement , which uses FleetIQ algorithms 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 fleet must be in ACTIVE status before a game session can be created in it.

This operation can be used 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.

If successful, a workflow is initiated to start a new game session. A GameSession object is returned containing the game session configuration and status. When the status is ACTIVE , game session connection information is provided and player sessions can be created 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.

Game session logs are retained for all active game sessions for 14 days. To access the logs, call GetGameSessionLogUrl to download the log files.

Available in Amazon GameLift Local.

Options

--fleet-id (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.

--alias-id (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.

--maximum-player-session-count (integer)

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.

--game-properties (list)

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 ).

(structure)

Set of key-value pairs that contain information about a game session. When included in a game session request, these properties communicate details to be used when setting up the new game session. For example, a game property might specify a game mode, level, or map. Game properties are passed to the game server process when initiating a new game session. For more information, see the GameLift Developer Guide .

Key -> (string)

The game property identifier.

Value -> (string)

The game property value.

Shorthand Syntax:

Key=string,Value=string ...

JSON Syntax:

[
  {
    "Key": "string",
    "Value": "string"
  }
  ...
]

--creator-id (string)

A unique identifier for a player or entity creating the game session. This parameter is required when requesting a new game session on a fleet with a resource creation limit policy. This type of policy limits the number of concurrent active game sessions that one player can create within a certain time span. GameLift uses the CreatorId to evaluate the new request against the policy.

--game-session-id (string)

This parameter is no longer preferred. Please 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.

--idempotency-token (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.

--game-session-data (string)

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 ).

--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 .

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.
