Synopsis

Invokes the StartGameSessionPlacement operation against Amazon GameLift Service.

Syntax

Start-GMLGameSessionPlacement
-GameSessionName <String>
-DesiredPlayerSession <DesiredPlayerSession[]>
-GameProperty <GameProperty[]>
-GameSessionData <String>
-GameSessionQueueName <String>
-MaximumPlayerSessionCount <Int32>
-PlacementId <String>
-PlayerLatency <PlayerLatency[]>
-Force <SwitchParameter>

Description

Places a request for a new game session in a queue (see CreateGameSessionQueue). When processing a placement request, Amazon GameLift searches for available resources on the queue's destinations, scanning each until it finds resources or the placement request times out. A game session placement request can also request player sessions. When a new game session is successfully created, Amazon GameLift creates a player session for each player included in the request. When placing a game session, by default Amazon GameLift tries each fleet in the order they are listed in the queue configuration. Ideally, a queue's destinations are listed in preference order. Alternatively, when requesting a game session with players, you can also provide latency data for each player in relevant regions. Latency data indicates the performance lag a player experiences when connected to a fleet in the region. Amazon GameLift uses latency data to reorder the list of destinations to place the game session in a region with minimal lag. If latency data is provided for multiple players, Amazon GameLift calculates each region's average lag for all players and reorders to get the best game play across all players. To place a new game session request, specify the following:
  • The queue name and a set of game session properties and settings
  • A unique ID (such as a UUID) for the placement. You use this ID to track the status of the placement request
  • (Optional) A set of IDs and player data for each player you want to join to the new game session
  • Latency data for all players (if you want to optimize game play for the players)
If successful, a new game session placement is created. To track the status of a placement request, call DescribeGameSessionPlacement and check the request's status. If the status is FULFILLED, a new game session has been created and a game session ARN and region are referenced. If the placement request times out, you can resubmit the request or retry it with a different queue. Game-session-related operations include:

Parameters

-DesiredPlayerSession <DesiredPlayerSession[]>
Set of information on each player to create a player session for.
Required?False
Position?Named
Accept pipeline input?False
-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
-GameProperty <GameProperty[]>
Set of developer-defined properties for a game session, formatted as a set of type:value pairs. These properties are included in the GameSession object, which is passed to the game server with a request to start a new game session (see Start a Game Session).
Required?False
Position?Named
Accept pipeline input?False
-GameSessionData <String>
Set of developer-defined game session properties, formatted as a single string value. This data is included in the GameSession object, which is passed to the game server with a request to start a new game session (see Start a Game Session).
Required?False
Position?Named
Accept pipeline input?False
-GameSessionName <String>
Descriptive label that is associated with a game session. Session names do not need to be unique.
Required?False
Position?1
Accept pipeline input?True (ByValue, )
-GameSessionQueueName <String>
Name of the queue to use to place the new game session.
Required?False
Position?Named
Accept pipeline input?False
-MaximumPlayerSessionCount <Int32>
Maximum number of players that can be connected simultaneously to the game session.
Required?False
Position?Named
Accept pipeline input?False
-PlacementId <String>
Unique identifier to assign to the new game session placement. This value is developer-defined. The value must be unique across all regions and cannot be reused unless you are resubmitting a canceled or timed-out placement request.
Required?False
Position?Named
Accept pipeline input?False
-PlayerLatency <PlayerLatency[]>
Set of values, expressed in milliseconds, indicating the amount of latency that a player experiences when connected to AWS regions. This information is used to try to place the new game session where it can offer the best possible gameplay experience for the players.
Required?False
Position?Named
Accept pipeline input?False

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 GameSessionName parameter.

Outputs

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