Amazon GameLift Construct Library

This module is part of the AWS Cloud Development Kit project.

import gamelift "github.com/aws/aws-cdk-go/awscdk"

There are no official hand-written (L2) constructs for this service yet. Here are some suggestions on how to proceed:

An experimental construct library for this service is available in preview. Since it is not stable yet, it is distributed as a separate package so that you can pin its version independently of the rest of the CDK. See the package:

@aws-cdk/aws-gamelift-alpha

There are no hand-written (L2) constructs for this service yet. However, you can still use the automatically generated L1 constructs, and use this service exactly as you would using CloudFormation directly.

For more information on the resources and properties available for this service, see the CloudFormation documentation for AWS::GameLift.

(Read the CDK Contributing Guide and submit an RFC if you are interested in contributing to this construct library.)

Functions

func CfnAlias_CFN_RESOURCE_TYPE_NAME 

func CfnAlias_CFN_RESOURCE_TYPE_NAME() *string

func CfnAlias_IsCfnElement 

func CfnAlias_IsCfnElement(x interface{}) *bool

Returns `true` if a construct is a stack element (i.e. part of the synthesized cloudformation template).

Uses duck-typing instead of `instanceof` to allow stack elements from different versions of this library to be included in the same stack.

Returns: The construct as a stack element or undefined if it is not a stack element.

func CfnAlias_IsCfnResource 

func CfnAlias_IsCfnResource(construct constructs.IConstruct) *bool

Check whether the given construct is a CfnResource.

func CfnAlias_IsConstruct 

func CfnAlias_IsConstruct(x interface{}) *bool

Checks if `x` is a construct.

Use this method instead of `instanceof` to properly detect `Construct` instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the `constructs` library on disk are seen as independent, completely different libraries. As a consequence, the class `Construct` in each copy of the `constructs` library is seen as a different class, and an instance of one class will not test as `instanceof` the other class. `npm install` will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the `constructs` library can be accidentally installed, and `instanceof` will behave unpredictably. It is safest to avoid using `instanceof`, and using this type-testing method instead.

Returns: true if `x` is an object created from a class which extends `Construct`.

A CloudFormation `AWS::GameLift::Alias`.

The `AWS::GameLift::Alias` resource creates an alias for an Amazon GameLift (GameLift) fleet destination. There are two types of routing strategies for aliases: simple and terminal. A simple alias points to an active fleet. A terminal alias displays a message instead of routing players to an active fleet. For example, a terminal alias might display a URL link that directs players to an upgrade site. You can use aliases to define destinations in a game session queue or when requesting new game sessions.

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import "github.com/aws/aws-cdk-go/awscdk"

cfnAlias := awscdk.Aws_gamelift.NewCfnAlias(this, jsii.String("MyCfnAlias"), &cfnAliasProps{

	// The time span used in evaluating the resource creation limit policy.
	PolicyPeriodInMinutes *float64 `field:"optional" json:"policyPeriodInMinutes" yaml:"policyPeriodInMinutes"`
}

A policy that limits the number of game sessions a player can create on the same fleet.

This optional policy gives game owners control over how players can consume available game server resources. A resource creation policy makes the following statement: "An individual player can create a maximum number of new game sessions within a specified time period".

The policy is evaluated when a player tries to create a new game session. For example, assume you have a policy of 10 new game sessions and a time period of 60 minutes. On receiving a `CreateGameSession` request, Amazon GameLift checks that the player (identified by `CreatorId` ) has created fewer than 10 game sessions in the past 60 minutes.

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import "github.com/aws/aws-cdk-go/awscdk"

	// A collection of server process configurations that identify what server processes to run on each instance in a fleet.
	ServerProcesses interface{} `field:"optional" json:"serverProcesses" yaml:"serverProcesses"`
}

A collection of server process configurations that describe the set of processes to run on each instance in a fleet.

Server processes run either an executable in a custom game build or a Realtime Servers script. GameLift launches the configured processes, manages their life cycle, and replaces them as needed. Each instance checks regularly for an updated runtime configuration.

A GameLift instance is limited to 50 processes running concurrently. To calculate the total number of processes in a runtime configuration, add the values of the `ConcurrentExecutions` parameter for each ServerProcess. Learn more about [Running Multiple Processes on a Fleet](https://docs.aws.amazon.com/gamelift/latest/developerguide/fleets-multiprocess.html) .

A CloudFormation `AWS::GameLift::GameServerGroup`.

*This operation is used with the Amazon GameLift FleetIQ solution and game server groups.*

Creates a GameLift FleetIQ game server group for managing game hosting on a collection of Amazon EC2 instances for game hosting. This operation creates the game server group, creates an Auto Scaling group in your AWS account , and establishes a link between the two groups. You can view the status of your game server groups in the GameLift console. Game server group metrics and events are emitted to Amazon CloudWatch.

Before creating a new game server group, you must have the following:

- An Amazon EC2 launch template that specifies how to launch Amazon EC2 instances with your game server build. For more information, see [Launching an Instance from a Launch Template](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-launch-templates.html) in the *Amazon EC2 User Guide* . - An IAM role that extends limited access to your AWS account to allow GameLift FleetIQ to create and interact with the Auto Scaling group. For more information, see [Create IAM roles for cross-service interaction](https://docs.aws.amazon.com/gamelift/latest/fleetiqguide/gsg-iam-permissions-roles.html) in the *GameLift FleetIQ Developer Guide* .

To create a new game server group, specify a unique group name, IAM role and Amazon EC2 launch template, and provide a list of instance types that can be used in the group. You must also set initial maximum and minimum limits on the group's instance count. You can optionally set an Auto Scaling policy with target tracking based on a GameLift FleetIQ metric.

Once the game server group and corresponding Auto Scaling group are created, you have full access to change the Auto Scaling group's configuration as needed. Several properties that are set when creating a game server group, including maximum/minimum size and auto-scaling policy settings, must be updated directly in the Auto Scaling group. Keep in mind that some Auto Scaling group properties are periodically updated by GameLift FleetIQ as part of its balancing activities to optimize for availability and cost.

A CloudFormation `AWS::GameLift::GameSessionQueue`.

The `AWS::GameLift::GameSessionQueue` resource creates a placement queue that processes requests for new game sessions. A queue uses FleetIQ algorithms to determine the best placement locations and find an available game server, then prompts the game server to start a new game session. Queues can have destinations (GameLift fleets or aliases), which determine where the queue can place new game sessions. A queue can have destinations with varied fleet type (Spot and On-Demand), instance type, and AWS Region .

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.

	DestinationArn *string `field:"optional" json:"destinationArn" yaml:"destinationArn"`
}

A fleet or alias designated in a game session queue.

Queues fulfill requests for new game sessions by placing a new game session on any of the queue's destinations.

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import "github.com/aws/aws-cdk-go/awscdk"

destinationProperty := &destinationProperty{
	destinationArn: jsii.String("destinationArn"),

type CfnGameSessionQueue_FilterConfigurationProperty 

type CfnGameSessionQueue_FilterConfigurationProperty struct {
	// A list of locations to allow game session placement in, in the form of AWS Region codes such as `us-west-2` .
	AllowedLocations *[]*string `field:"optional" json:"allowedLocations" yaml:"allowedLocations"`
}

A list of fleet locations where a game session queue can place new game sessions.

You can use a filter to temporarily turn off placements for specific locations. For queues that have multi-location fleets, you can use a filter configuration allow placement with some, but not all of these locations.

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import "github.com/aws/aws-cdk-go/awscdk"

filterConfigurationProperty := &filterConfigurationProperty{
	allowedLocations: []*string{
		jsii.String("allowedLocations"),
	},
}

type CfnGameSessionQueue_PlayerLatencyPolicyProperty 

type CfnGameSessionQueue_PlayerLatencyPolicyProperty struct {
	// The maximum latency value that is allowed for any player, in milliseconds.
	//
	// All policies must have a value set for this property.
	MaximumIndividualPlayerLatencyMilliseconds *float64 `field:"optional" json:"maximumIndividualPlayerLatencyMilliseconds" yaml:"maximumIndividualPlayerLatencyMilliseconds"`
	// The length of time, in seconds, that the policy is enforced while placing a new game session.
	//
	// A null value for this property means that the policy is enforced until the queue times out.
	PolicyDurationSeconds *float64 `field:"optional" json:"policyDurationSeconds" yaml:"policyDurationSeconds"`
}

The queue setting that determines the highest latency allowed for individual players when placing a game session.

When a latency policy is in force, a game session cannot be placed with any fleet in a Region where a player reports latency higher than the cap. Latency policies are only enforced when the placement request contains player latency information.

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import "github.com/aws/aws-cdk-go/awscdk"

playerLatencyPolicyProperty := &playerLatencyPolicyProperty{

type CfnGameSessionQueue_PriorityConfigurationProperty 

type CfnGameSessionQueue_PriorityConfigurationProperty struct {
	// The prioritization order to use for fleet locations, when the `PriorityOrder` property includes `LOCATION` .
	//
	// Locations are identified by AWS Region codes such as `us-west-2` . Each location can only be listed once.
	LocationOrder *[]*string `field:"optional" json:"locationOrder" yaml:"locationOrder"`
	// The recommended sequence to use when prioritizing where to place new game sessions.
	//
	// Each type can only be listed once.
	//
	// - `LATENCY` -- FleetIQ prioritizes locations where the average player latency (provided in each game session request) is lowest.
	// - `COST` -- FleetIQ prioritizes destinations with the lowest current hosting costs. Cost is evaluated based on the location, instance type, and fleet type (Spot or On-Demand) for each destination in the queue.
	// - `DESTINATION` -- FleetIQ prioritizes based on the order that destinations are listed in the queue configuration.
	// - `LOCATION` -- FleetIQ prioritizes based on the provided order of locations, as defined in `LocationOrder` .
	PriorityOrder *[]*string `field:"optional" json:"priorityOrder" yaml:"priorityOrder"`
}

Custom prioritization settings for use by a game session queue when placing new game sessions with available game servers.

When defined, this configuration replaces the default FleetIQ prioritization process, which is as follows:

- If player latency data is included in a game session request, destinations and locations are prioritized first based on lowest average latency (1), then on lowest hosting cost (2), then on destination list order (3), and finally on location (alphabetical) (4). This approach ensures that the queue's top priority is to place game sessions where average player latency is lowest, and--if latency is the same--where the hosting cost is less, etc. - If player latency data is not included, destinations and locations are prioritized first on destination list order (1), and then on location (alphabetical) (2). This approach ensures that the queue's top priority is to place game sessions on the first destination fleet listed. If that fleet has multiple locations, the game session is placed on the first location (when listed alphabetically).

Changing the priority order will affect how game sessions are placed.

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import "github.com/aws/aws-cdk-go/awscdk"

priorityConfigurationProperty := &priorityConfigurationProperty{
	locationOrder: []*string{

A CloudFormation `AWS::GameLift::MatchmakingConfiguration`.

The `AWS::GameLift::MatchmakingConfiguration` resource defines a new matchmaking configuration for use with FlexMatch. Whether you're using FlexMatch with GameLift hosting or as a standalone matchmaking service, the matchmaking configuration sets out rules for matching players and forming teams. If you're using GameLift hosting, it also defines how to start game sessions for each match. Your matchmaking system can use multiple configurations to handle different game scenarios. All matchmaking requests identify the matchmaking configuration to use and provide player attributes that are consistent with that configuration.

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.

A CloudFormation `AWS::GameLift::MatchmakingRuleSet`.

Creates a new rule set for FlexMatch matchmaking. A rule set describes the type of match to create, such as the number and size of teams. It also sets the parameters for acceptable player matches, such as minimum skill level or character type.

To create a matchmaking rule set, provide unique rule set name and the rule set body in JSON format. Rule sets must be defined in the same Region as the matchmaking configuration they are used with.

Since matchmaking rule sets cannot be edited, it is a good idea to check the rule set syntax.

A CloudFormation `AWS::GameLift::Script`.

The `AWS::GameLift::Script` resource creates a new script record for your Realtime Servers script. Realtime scripts are JavaScript that provide configuration settings and optional custom game logic for your game. The script is deployed when you create a Realtime Servers fleet to host your game sessions. Script logic is executed during an active game session.

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import "github.com/aws/aws-cdk-go/awscdk"

cfnScript := awscdk.Aws_gamelift.NewCfnScript(this, jsii.String("MyCfnScript"), &cfnScriptProps{
