The Amazon GameLift plugin for the Unreal and Unity game engines provides tools and workflows that streamline your steps to getting a game up and running with Amazon GameLift. Amazon GameLift is a fully managed cloud hosting service that game developers can use to manage and scale dedicated game servers for session-based multiplayer games.

The latest plugin versions offer the following enhancements:

  • Guided workflow for hosting with Managed Containers. This workflow walks you through the steps to set up a container image with your game server software, and deploy a cloud-based hosting solution for your game server. The workflow offers two different deployment scenarios: a simple deployment and a more complete deployment with a game session placement queue and a FlexMatch matchmaker. Each scenario generates Amazon GameLift container fleets and supporting AWS resources.

  • Improved process for setting up AWS user profiles and managing AWS access credentials for plugin use. You can maintain multiple profiles to work with different AWS accounts, account users, and regions.

  • Additional functionality to update existing container fleets. You can deploy new container images (such as for game server version updates) and change fleet configuration settings without having to start from the beginning.

  • Improved workflows for hosting with Amazon GameLift Anywhere fleets and Managed EC2. Improvements based on customer feedback include better guidance with tips and links to helpful resources.

The deployment scenarios for Managed Containers and Managed EC2 solutions use AWS CloudFormation templates to create and deploy the AWS resources for each scenario. These templates are included in the Amazon GameLift plugin download and are editable. You can use them as is or modify them for your game.

Updated SDK versions:

  • AWS SDK 1.11.445

  • Server SDK, version 5.2.0 (all languages)

Amazon GameLift releases for general availability a new hosting solution for containerized game server workloads. With this release, game developers can now take advantage of the benefits of containerization including consistent, secure environments, a simplified deployment process, and optimized resource utilization.

Managed container fleets use Amazon EC2 instances that are managed by Amazon GameLift on your behalf and based on your configurations. You build a custom container architecture for your game and provide container images by storing them in a Amazon Elastic Container Registry (Amazon ECR) repository. Container fleets are available for Linux-based game servers only. Game servers must be integrated with Server SDK 5.2.0 or greater.

With managed container fleets, you get the same benefits as with managed EC2 fleets. This includes support for On-Demand and Spot instance types, intelligent capacity scaling, game session placement with queues, and matchmaking. You also get the same metrics as other fleet types along with some new ones for containers. Other features for container fleets include:

  • Alignment with serverless experience for containerized workloads. Run one game server process per container and pack many containers onto each fleet instance for optimal resource usage. If you prefer to have containers with multiple game server processes, you can use the Amazon GameLift Agent for automated host management.

  • Streamlined fleet creation. Container fleets are designed to require minimal deployment configuration settings, with sensible suggested/default values. You can quickly deploy a working fleet, and then customize individual settings as needed.

  • Versioning tools for container architecture. You can now update a container group definition (which is similar to a container "task"), maintain multiple versions, and specify which version to deploy to a fleet..

  • Fleet update tools. With container fleets, you no longer need to create a new fleet when you want to release a game server version update. Instead, you can now update your container image and deploy the updates to existing fleets.

You can build Amazon GameLift container fleets in any AWS Region where Amazon GameLift supports multi-location fleets, and you can deploy container fleet instances to any supported remote location. For more details, see Amazon GameLift service locations. Managed containers is not currently available in AWS China Regions.

Updated SDK versions:

C++ Server SDK, version 5.1.3

  • New logging capabilities. You can now access SDK request logs.

  • Improved SDK message transmission reliability. The SDK now uses more robust reconnection mechanisms to recover in the event of network interruptions or random message drops.

Updated plugin versions:

Amazon GameLift plugin for Unreal Engine, version 1.1.2

  • Upgraded to support the latest version of the C++ server SDK 5.1.3.

  • In the Amazon GameLift plugin for Unreal Engine, when browsing for a server build executable for a fleet, you now have the option to browse All Files.

C++ Server SDK Plugin for Unreal, version 5.1.2

  • Upgraded to support the latest version of the C++ server SDK 5.1.3.

Based on customer feedback, we've clarified the Amazon GameLift workflow for creating a managed EC2 fleet and getting it ready to host game sessions. Improvements include:

  • We've provided more specific and accurate descriptions of each phase of the fleet creation process. This improved visibility makes it easier to pinpoint and resolve issues faster.

  • The Building and Activating phases better separate instance deployment tasks (building) from tasks to start game server processes and connect to the Amazon GameLift service (activating). This change makes it easier to recognize the likely cause of issues. In addition, you can now remotely connect to fleets when they're in the Activating phase.

  • Two new fleet creation events communicate the success or failure of game server install scripts. If you're game server build includes an install script, Amazon GameLift attempts to run the script and emits one of the following new events:

    • FLEET_CREATION_COMPLETED_INSTALLER

    • FLEET_CREATION_FAILED_INSTALLER

Learn more:

Based on customer feedback, we've made the following updates to the Amazon GameLift console experience:

  • Your display preferences for pages are now automatically saved to your AWS account user and applied whenever you return to the page. Display preferences let you choose what information to include in a table display, such as on the Fleets listing page. Customize your display preferences by using the Gear icon representing settings or configuration options. icon in the upper right corner of a table.

  • The Create Fleet workflow for managed EC2 fleets has been streamlined to combine the selection of fleet locations and instance types. We've made it easier for you to find the right instance type for your fleet, even when you change your locations selections.

With Amazon GameLift managed hosting, you can now deploy game server resources in Nigeria, West Africa, and extend the reach of your games to players throughout Africa. Use AWS Local Zones to place game servers geographically closer to your players to reduce latency and significantly improve gameplay.

To immediately begin hosting game sessions in Nigeria, add the new Nigeria Local Zone as a remote location to a new or existing multi-location fleet. If your game uses Amazon GameLift FlexMatch, update fleets in your matchmaking queue to include the new Local Zone. With multi-location fleets, you can directly manage hosting capacity in each location.

The parent AWS Region for the Lagos, Nigeria Local Zone is the Africa (Cape Town) Region (af-south-1), which Amazon GameLift also supports as a remote location. The Nigeria Local Zone name is af-south-1-los-1.

The Amazon GameLift console now offers a player session lookup tool that lets you retrieve player session information by game session ID, player session ID, or player ID. Games that use FlexMatch matchmaking automatically generate player sessions for every matched player. For all other games, player sessions are an optional feature.

You can find the player session lookup tool in the main navigation for the Amazon GameLift console. View individual player sessions or compare data across multiple player sessions. You can also open player session data when viewing a game session detail page.

Amazon GameLift is now offering a preview of container fleets, which give you improved portability, scalability, fault tolerance, and agility.

In container fleets, Amazon EC2 instances host one or more of your containers. These containers include your game server along with whatever it requires, including dependencies and configurations. Examples of dependencies include SDKs and software packages. After you upload your container to your private Amazon Elastic Container Registry, Amazon GameLift populates your fleet with the container.

To function in a container fleet, your game server must run in Linux and be integrated with Server SDK 5.x. In a container fleet, you have fine-tuned control of hosting resources so that you can optimize consumption of resources such as CPU units and memory. You can also host multiple game servers in a container to reduce the use of resources.

In a container fleet you get many of the same benefits that other types of fleets have such as On-Demand instance types, scaling (automatic and manual), queues, and matchmaking. You also get the same metrics as other fleet types along with some new ones for containers. Container fleets give you global reach to players in these locations regions:

  • ap-northeast-1

  • ap-northeast-2

  • ap-southeast-2

  • eu-central-1

  • eu-west-1

  • us-east-1

  • us-west-2

To reach even more regions and local zones, create multi-location containers fleets.

You've already been able to set game properties when creating game sessions, and to search game sessions for specified properties. Now you can also add and update these properties in an active game session.

For example, your players vote on a map that they want to play on. Your game client calls UpdateGameSession to modify a GameProperty value to {"Key": "map", "Value":"jungle"}. Your game then implements the new map for the players in the game session.

Game administrators can also retrieve useful data from game properties by using the SearchGameSessions operation. For example, administrators can list game sessions that have a Status value of ACTIVE and this game property: {"Key": "map", "Value":"desert"}.

You can now manage your entire Amazon GameLift resource stack using Infrastructure as Code (IaC) tools. These tools include AWS CloudFormation, and also third-party tools such as Terraform and Pulumi. With this added support, you can now focus on building your game, and leverage DevOps strategies to take care of resource management, CI/CD, and deployment to your customers.

You can also now provision and configure all Amazon GameLift resources types by using the AWS Cloud Control API. You can continue to work with resources using the Amazon GameLift APIs or the AWS CloudFormation templates for Amazon GameLift.

For details about the Amazon GameLift resources available through IaC, see the Amazon GameLift resource type reference Amazon GameLift resource type reference.

In addition, you can now automatically scale your fleets using AWS CloudFormation templates or the AWS Cloud Control API by using the new Fleet property: ScalingPolicies.

The Cloud Control API gives developers a standard set of APIs to create, read, update, delete, and list resources (CRUDL) across hundreds of AWS services and multiple third-party tools like Terraform and Pulumi.

Updated SDK versions: AWS SDK 1.11.193

The new Amazon GameLift shared credentials feature allows applications that are deployed on managed EC2 fleets to interact with other AWS resources. This update affects applications that you bundle and deploy along with game server binaries integrated with server SDK version 5.x or later. (Game server executables can already request credentials using the server SDK 5.x GetFleetRoleCredentials() action.)

For example, if you want to deploy your game server build with an Amazon CloudWatch agent to collect EC2 instance metrics and other data, the agent needs permission to interact with your CloudWatch resources. To do this, you must first set up an AWS Identity and Access Management IAM) role with permissions to use the CloudWatch resources, and then configure a fleet with the IAM role and shared credentials enabled. When Amazon GameLift deploys your game server build to each EC2 instance, it generates a shared credentials file and stores it on the instance. All applications on the instance can use the shared credentials. Amazon GameLift automatically refreshes the temporary credentials throughout the life of the instance.

You can enable shared credentials when you create a managed EC2 fleet using the following methods:

  • In the Amazon GameLift console fleet creation workflow.

  • When calling the Amazon GameLift service API operation CreateFleet using the new parameter InstanceRoleCredentialsProvider.

  • When calling the AWS CLI operation aws gamelift create-fleet with the parameter instance-role-credentials-provider.

Amazon GameLift managed hosting is now available in 21 AWS Regions. The new Regions are Cape Town (af-south-1), Bahrain (me-south-1), Hong Kong (ap-east-1), Milan (eu-south-1), Paris (eu-west-3), and Stockholm (eu-north-1).

With the new Amazon GameLift multi-location fleets feature, you can now set up a single fleet to host your game servers in any or all of 20 Amazon GameLift-supported Regions (Beijing Region excepted). This feature aims to significantly reduce the work required to set up and maintain Amazon GameLift hosting resources globally. Multi-location fleets can be created in the following AWS Regions: us-east-1 (N. Virginia), us-west-2 (Oregon), eu-central-1 (Frankfurt), eu-west-1 (Ireland), ap-southeast-2 (Sydney), ap-northeast-1 (Tokyo), and ap-northeast-2 (Seoul). In all other Regions, you can continue to set up single-location fleets as needed. All fleets that were created before this release are single-location fleets. Using multi-location fleets does not affect your hosting costs. Amazon GameLift pricing is based on the type, location, and volume of instances that you use. (For more information, see Amazon GameLift pricing.) AWS CloudFormation support for multi-location fleets will be available soon.

Note

Multi-location fleets are not available in the China Regions. Amazon GameLift resources that reside in China Regions cannot interact with or be used by resources in other Amazon GameLift Regions.

Updated SDK versions: AWS SDK 1.8.95

Amazon GameLift FlexMatch is a customizable matchmaking service for multiplayer games. Initially designed for users of Amazon GameLift managed hosting, FlexMatch can now be integrated into games that use other hosting systems, including peer-to-peer, proprietary on-premises computing, and cloud compute primitive types. Games that use Amazon GameLift FleetIQ for game hosting on Amazon EC2 can now implement matchmaking with FlexMatch.

FlexMatch provides a robust matchmaking algorithm and rules language that gives you wide latitude to customize the matchmaking process so that players are matched together based on key player characteristics and reported latency. In addition, FlexMatch offers a matchmaking request workflow that supports features such as player parties, player acceptance, and match backfill. When you use FlexMatch with Amazon GameLift managed hosting or Realtime Servers, the matchmaker automatically uses Amazon GameLift to find hosting resources and start a new game session for newly formed matches. When using FlexMatch as a standalone service, the matchmaker delivers match results back to your game, which can then start a new game session using your hosting solution.

API operations for FlexMatch are part of the Amazon GameLift service API, which is included in the AWS SDK and the AWS Command Line Interface (AWS CLI). This release includes these updates to support standalone matchmaking:

  • The API resource MatchmakingConfiguration has the following changes:

    • New property, FlexMatchMode indicates whether the matchmaker is being used with Amazon GameLift managed hosting or as standalone matchmaking.

    • Property GameSessionQueueArns is not required when FlexMatchMode is set to standalone.

    • These properties are not used with standalone matchmaking: AdditionalPlayerCount, BackfillMode, GameProperties, GameSessionData.

  • The automatic backfill feature is not available with standalone matchmaking.

Updated SDK versions: AWS SDK 1.8.95

The list of Amazon EC2 instance types supported by Amazon GameLift now includes three new instance families: C5a, M5a, and R5a. These families consist of AMD compute-optimized instances that are powered by AMD EPYC processors running at frequencies up to 3.3. GHz. The AMD instances are x86 compatible; games that are currently running on Amazon GameLift can be deployed to AMD instance types without alteration. The new instances are available in the following AWS Regions: US East (N. Virginia and Ohio), US West (Oregon and N. California), Central Canada (Montreal), South America (Sao Paulo), EU Central (Frankfurt), EU West (London and Ireland), Asia Pacific South (Mumbai), Asia Pacific Northeast (Seoul and Tokyo), and Asia Pacific Southeast (Singapore and Sydney).

Updated SDK versions: Amazon GameLift Server SDK 4.0.2

The new Server SDK version 4.0.2 fixes a known issue with the API operation StartMatchBackfill(). This operation now returns a correct response to a match backfill request.

The issue did not affect the match backfill process, and there is no change to how this feature works. The issue may have impacted log messaging and error handling for match backfill requests.

Download the latest version of the Amazon GameLift Server SDK at Amazon GameLift getting started.

FlexMatch users can now adjust the following default behaviors for the matchmaking process. These customizations are set in a matchmaking rule set. There are no changes to the Amazon GameLift SDKs.

  • Prioritize backfill tickets: You can choose to raise or lower how match backfill tickets are prioritized when searching for acceptable matches. Prioritizing backfill tickets is useful when the auto-backfill feature is enabled. Use the algorithm property backfillPriority.

  • Pre-sort to optimize match consistency and efficiency: Configure your matchmaker to pre-sort the ticket pool before batching tickets for evaluation. By pre-sorting tickets based on key player attributes, your resulting matches tend to have players who are more similar in those attributes. You can also boost efficiency in the evaluation process by pre-sorting on the same attributes that are used in match rules. Use the algorithm property sortByAttributes with the strategy property set to "sorted".

  • Adjust how expansion wait times are triggered: Choose between triggering expansions based on the age of the newest (default) or oldest ticket in an incomplete match. Triggering on the oldest ticket tends to complete matches faster, while triggering on the newest ticket leads to higher match quality. Use the algorithm property expansionAgeSelection.

Updated SDK versions: AWS SDK 1.7.249

You can now take advantage of AWS resource management tools with Amazon GameLift resources. In particular, all key Amazon GameLift resources—builds, scripts, fleets, game session queues, matchmaking configurations, and matchmaking rule sets—are now assigned Amazon Resource Name (ARN) values. A resource ARN provides a consistent identifier that is unique across all AWS Regions. They can be used to create resource-specific AWS Identity and Access Management (IAM) permissions policies. Resources are now assigned an ARN and also the pre-existing resource identifier, which is not Region-specific.

In addition, Amazon GameLift resources now support tagging. You can use tags to organize resources, create IAM permissions policies to manage access to groups of resources, customize AWS cost breakdowns, etc. When managing tags for Amazon GameLift resources, use the Amazon GameLift API actions TagResource(), UntagResource(), and ListTagsForResource().
