Amazon GameLift Service
Welcome to the Amazon GameLift API Reference. Amazon GameLift is a managed Amazon Web Services (AWS) service for developers who need a scalable, server-based solution for multiplayer games. Amazon GameLift provides setup and deployment of game servers, and handles infrastructure scaling and session management. For more information about the GameLift service, including a feature overview, getting started guide, and tutorial, see the accompanying Amazon GameLift Developer Guide.

This reference describes the low-level service API for GameLift. You can call this API directly or use the AWS SDK for your preferred language. The AWS SDK includes a set of high-level GameLift actions multiplayer game sessions. Alternatively, you can use the AWS command-line interface (CLI) tool, which includes commands for GameLift. For administrative actions, you can use the Amazon GameLift console.

- Method Detail
  - setEndpoint
```
void setEndpoint(String endpoint)
```
    Overrides the default endpoint for this client ("https://gamelift.us-east-1.amazonaws.com"). Callers can use this method to control which AWS region they want to work with.
    Callers can pass in just the endpoint (ex: "gamelift.us-east-1.amazonaws.com") or a full URL, including the protocol (ex: "https://gamelift.us-east-1.amazonaws.com"). If the protocol is not specified here, the default protocol from this client's ClientConfiguration will be used, which by default is HTTPS.
    For more information on using AWS regions with the AWS SDK for Java, and a complete list of all available endpoints for all AWS services, see: http://developer.amazonwebservices.com/connect/entry.jspa?externalID= 3912
    This method is not threadsafe. An endpoint should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.
    
    Parameters:
    endpoint - The endpoint (ex: "gamelift.us-east-1.amazonaws.com") or a full URL, including the protocol (ex: "https://gamelift.us-east-1.amazonaws.com") of the region specific AWS endpoint this client will communicate with.
  - setRegion
```
void setRegion(Region region)
```
    An alternative to setEndpoint(String), sets the regional endpoint for this client's service calls. Callers can use this method to control which AWS region they want to work with.
    By default, all service endpoints in all regions use the https protocol. To use http instead, specify it in the ClientConfiguration supplied at construction.
    This method is not threadsafe. A region should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.
    
    Parameters:
    region - The region this client will communicate with. See Region.getRegion(com.amazonaws.regions.Regions) for accessing a given region. Must not be null and must be a region where the service is available.
    See Also:
    Region.getRegion(com.amazonaws.regions.Regions), Region.createClient(Class, com.amazonaws.auth.AWSCredentialsProvider, ClientConfiguration), Region.isServiceSupported(String)
  - createAlias
```
CreateAliasResult createAlias(CreateAliasRequest createAliasRequest)
```
    Creates an alias for a fleet. You can use an alias to anonymize your fleet by referencing an alias instead of a specific fleet when you create game sessions. Amazon GameLift supports two types of routing strategies for aliases: simple and terminal. Use a simple alias to point to an active fleet. Use a terminal alias to display a message to incoming traffic instead of routing players to an active fleet. This option is useful when a game server is no longer supported but you want to provide better messaging than a standard 404 error.
    
    To create a fleet alias, specify an alias name, routing strategy, and optional description. If successful, a new alias record is returned, including an alias ID, which you can reference when creating a game session. To reassign the alias to another fleet ID, call UpdateAlias.
    
    Parameters:
    createAliasRequest - Represents the input for a request action.
    
    Returns:
    Result of the CreateAlias operation returned by the service.
    
    Throws:
    
    UnauthorizedException - The client failed authentication. Such requests should not be retried without valid authentication credentials.
    
    InvalidRequestException - One or more parameters specified as part of the request are invalid. Please correct the invalid parameters before retrying.
    
    ConflictException - The requested operation would cause a conflict with the current state of a service resource associated with the request. Please resolve the conflict before retrying this request.
    
    InternalServiceException - The service encountered an unrecoverable internal failure while processing the request. Such requests can be retried by clients, either immediately or after a back-off period.
    
    LimitExceededException - The requested operation would cause the resource to exceed the allowed service limit. Please resolve the issue before retrying.
  - createBuild
```
CreateBuildResult createBuild(CreateBuildRequest createBuildRequest)
```
    Initializes a new build record and generates information required to upload a game build to Amazon GameLift. Once the build record has been created and is in an INITIALIZED state, you can upload your game build.
    
    To create a build, use the CLI command upload-build, which creates a new build record and uploads the build files in one step. (See the Amazon GameLift Developer Guide for more details on the CLI and the upload process.) Call the CreateBuild action only if you have your own Amazon Simple Storage Service (Amazon S3) client and need to manually upload your build files.
    
    To create a new build, optionally specify a build name and version. This metadata is stored with other properties in the build record and is displayed in the GameLift console (but not visible to players). If successful, this action returns the newly created build record along with an Amazon S3 storage location and AWS account credentials. Use the location and credentials to upload your game build.
    
    Parameters:
    createBuildRequest - Represents the input for a request action.
    
    Returns:
    Result of the CreateBuild operation returned by the service.
    
    Throws:
    
    UnauthorizedException - The client failed authentication. Such requests should not be retried without valid authentication credentials.
    
    InvalidRequestException - One or more parameters specified as part of the request are invalid. Please correct the invalid parameters before retrying.
    
    ConflictException - The requested operation would cause a conflict with the current state of a service resource associated with the request. Please resolve the conflict before retrying this request.
    
    InternalServiceException - The service encountered an unrecoverable internal failure while processing the request. Such requests can be retried by clients, either immediately or after a back-off period.
  - createFleet
```
CreateFleetResult createFleet(CreateFleetRequest createFleetRequest)
```
    Creates a new fleet to host game servers. A fleet consists of a set of Amazon Elastic Compute Cloud (Amazon EC2) instances of a certain type, which defines the CPU, memory, storage, and networking capacity of each host in the fleet. See Amazon EC2 Instance Types for more information. Each instance in the fleet hosts a game server created from the specified game build. Once a fleet is in an ACTIVE state, it can begin hosting game sessions.
    
    To create a new fleet, provide a name and the EC2 instance type for the new fleet, and specify the build and server launch path. Builds must be in a READY state before they can be used to build fleets. When configuring the new fleet, you can optionally (1) provide a set of launch parameters to be passed to a game server when activated; (2) limit incoming traffic to a specified range of IP addresses and port numbers; (3) set game session protection for all instances in the fleet, and (4) configure Amazon GameLift to store game session logs by specifying the path to the logs stored in your game server files. If the call is successful, Amazon GameLift performs the following tasks:
    - Creates a fleet record and sets the state to NEW.
    - Sets the fleet's capacity to 1 "desired" and 1 "active" EC2 instance count.
    - Creates an EC2 instance and begins the process of initializing the fleet and activating a game server on the instance.
    - Begins writing events to the fleet event log, which can be accessed in the GameLift console.
    Once a fleet is created, use the following actions to change certain fleet properties (server launch parameters and log paths cannot be changed):
    - UpdateFleetAttributes -- Update fleet metadata, including name and description.
    - UpdateFleetCapacity -- Increase or decrease the number of instances you want the fleet to maintain.
    - UpdateFleetPortSettings -- Change the IP addresses and ports that allow access to incoming traffic.
    Parameters:
    createFleetRequest - Represents the input for a request action.
    
    Returns:
    Result of the CreateFleet operation returned by the service.
    
    Throws:
    
    InternalServiceException - The service encountered an unrecoverable internal failure while processing the request. Such requests can be retried by clients, either immediately or after a back-off period.
    
    NotFoundException - A service resource associated with the request could not be found. Such requests should not be retried by clients.
    
    ConflictException - The requested operation would cause a conflict with the current state of a service resource associated with the request. Please resolve the conflict before retrying this request.
    
    LimitExceededException - The requested operation would cause the resource to exceed the allowed service limit. Please resolve the issue before retrying.
    
    InvalidRequestException - One or more parameters specified as part of the request are invalid. Please correct the invalid parameters before retrying.
    
    UnauthorizedException - The client failed authentication. Such requests should not be retried without valid authentication credentials.
  - createGameSession
```
CreateGameSessionResult createGameSession(CreateGameSessionRequest createGameSessionRequest)
```
    Creates a multiplayer game session for players. This action creates a game session record and assigns the new session to an instance in the specified fleet, which activates the server initialization process in your game server. A fleet must be in an ACTIVE state before a game session can be created for it.
    
    To create a game session, specify either a fleet ID or an alias ID and indicate the maximum number of players the game session allows. You can also provide a name and a set of properties for your game (optional). If successful, a GameSession object is returned containing session properties, including an IP address. By default, newly created game sessions are set to accept adding any new players to the game session. Use UpdateGameSession to change the creation policy.
    
    Parameters:
    createGameSessionRequest - Represents the input for a request action.
    
    Returns:
    Result of the CreateGameSession operation returned by the service.
    
    Throws:
    
    ConflictException - The requested operation would cause a conflict with the current state of a service resource associated with the request. Please resolve the conflict before retrying this request.
    
    InternalServiceException - The service encountered an unrecoverable internal failure while processing the request. Such requests can be retried by clients, either immediately or after a back-off period.
    
    UnauthorizedException - The client failed authentication. Such requests should not be retried without valid authentication credentials.
    
    InvalidFleetStatusException - The requested operation would cause a conflict with the current state of a resource associated with the request and/or the fleet. Please resolve the conflict before retrying.

  - putScalingPolicy
```
PutScalingPolicyResult putScalingPolicy(PutScalingPolicyRequest putScalingPolicyRequest)
```
    Creates or updates a scaling policy for a fleet. An active scaling policy prompts GameLift to track a certain metric for a fleet and automatically change the fleet's capacity in specific circumstances. Each scaling policy contains one rule statement. Fleets can have multiple scaling policies in force simultaneously.
    
    A scaling policy rule statement has the following structure:
    
    If [MetricName] is [ComparisonOperator] [Threshold] for [EvaluationPeriods] minutes, then [ScalingAdjustmentType] to/by [ScalingAdjustment].
    
    For example, this policy: "If the number of idle instances exceeds 20 for more than 15 minutes, then reduce the fleet capacity by 10 instances" could be implemented as the following rule statement:
    
    If [IdleInstances] is [GreaterThanOrEqualToThreshold] [20] for [15] minutes, then [ChangeInCapacity] by [-10].
    
    To create or update a scaling policy, specify a unique combination of name and fleet ID, and set the rule values. All parameters for this action are required. If successful, the policy name is returned. Scaling policies cannot be suspended or made inactive. To stop enforcing a scaling policy, call DeleteScalingPolicy.

    Throws:
    
    NotFoundException - A service resource associated with the request could not be found. Such requests should not be retried by clients.
    
    ConflictException - The requested operation would cause a conflict with the current state of a service resource associated with the request. Please resolve the conflict before retrying this request.
    
    InternalServiceException - The service encountered an unrecoverable internal failure while processing the request. Such requests can be retried by clients, either immediately or after a back-off period.
    
    UnauthorizedException - The client failed authentication. Such requests should not be retried without valid authentication credentials.
    
    InvalidGameSessionStatusException - The requested operation would cause a conflict with the current state of a resource associated with the request and/or the game instance. Such requests should not be retried by clients without resolving the conflict.
    
    InvalidRequestException - One or more parameters specified as part of the request are invalid. Please correct the invalid parameters before retrying.
  - shutdown
```
void shutdown()
```
    Shuts down this client object, releasing any resources that might be held open. This is an optional method, and callers are not expected to call it, but can if they want to explicitly release any open resources. Once a client has been shutdown, it should not be used to make any more requests.
  - getCachedResponseMetadata
```
ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)
```
    Returns additional metadata for a previously executed successful request, typically used for debugging issues where a service isn't acting as expected. This data isn't considered part of the result data returned by an operation, so it's available through this separate, diagnostic interface.
    Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing a request.
    
    Parameters:
    request - The originally executed request.
    
    Returns:
    The response metadata for the specified request, or null if none is available.
