Hello, I created custom service on Game Lift for my game(I use Linux instance) and all works fine, but I also want to use some assets from cloudFront(s3) and it works when I try locally on my machine(PC), but when I create my fleet with my build(linux) I got some errors: System.Exception: Unable to load ContentCatalogData from location https://*****.cloudfront.net/catalog_2022.******.json on second attempt. System.Exception: Failed to load content catalog. OperationException : ChainOperation failed because dependent operation failed System.Exception: Failed to load content catalog. UnityWebRequest result : ProtocolError : HTTP/1.1 403 Forbidden ResponseCode : 403, Method : GET url : https://*******.cloudfront.net/catalog_2022.******.json Are there any additional settings so I can access the cloudfront from my instance on gamelite? Thanks in advance!

Hi, I'm looking into scaling options for my fleet and wanted to try target-based scaling (as the simplest option) first. I set the buffer size to 50% (just for the sake of testing) but that doesn't seem to do anything. My fleet has a minimum of 2 instances and a maximum of 12. I would expect this setting to keep 6 instances spun up at all times. Again, this is not my production target, I'm just trying to get a feel for the feature so that I know whether it satisfies our requirements. Am I misunderstanding how this setting works? Thanks in advance

Assume my Gamelift Matchmaking can provide only max. 2 Game sessions. And assume I have a playerID "P1" and he has already a playersession with status "COMPLETED" for the only existing game sessions "G1" and "G2". What can I do, in order that start_matchmaking() creates a new playersession for player "P1" for the game sessions "G1" or "G2", so that he can join a game again? The only way I can think about is, to change the argument for "PlayerId" when calling start_matchmaking() again. But this sounds wrong. Alternatively there is function called CreatePlayerSession(). But for this I would need to store the GameSessionID beforehand, which makes it even more complicated than it should be.

Why are GameLift EC2 instances more expensive than regular EC2 instances? For example, a GameLift EC2 on-demand instance m5.large costs 0,146 USD per hour in eu-central-1. The same instance on EC2 costs 0,115 USD per hour in eu-central-1 So the GameLift service on top of EC2 makes the instance 27% more expensive. Is there anything included in the GameLift pricing that I would have to pay separately if I would build everything manually with EC2? Or is the GameLift API that saves me some programming the only reason for the increase of the instance price? I would like to evaluate if I can save a considerable amount of money by building a master server myself that is responsible for everything that GameLift can do for me, or if I would basically end up with the same running costs because I am missing the insight that I would be charged extra for some service when using EC2 manually that are already included in the GameLift calculation. Thanks in advance

Hello! I have a player session still ACTIVE after both players disconnected from the game. It's causing issues when I attempt to connect new clients to the server, saying that the match is full and they're being rejected. Is it possible for me to terminate this existing player session? I haven't found any documentation on this. Thanks in advance!

Does AWS have any equivalent product to Azures PlayFab?

I am using the unity plugin for gamelift and it failing to deploy the sample cloud formations. When I look at the event log in the cloud formation rollout I see the following: Resource handler returned message: "Error occurred during operation 'AWS::GameLift::Fleet'." (RequestToken: ..............., HandlerErrorCode: GeneralServiceException) Now, the page for the AWS gamelift unity plugin does say that this can occur for scenarios 4 and 5 if you are outside of your service limit due to billing concerns. However, this occurs for me on EVERY sample cloud formation, and its on an account that has been paying amazon and is in good standing. Further, when I check the gamelift service limits page it shows that I am inside my limits for the types of instances in the cloud formation. Any ideas on how I can get around this or what to do?

Hello, Here is my setup: * Using GameLift to host custom server for my game * Server is a headless Unity app * Server (and, therefore, client) uses Photon Fusion for simulation * I've integrated the SDKs, and everything works when testing with GameLift Local My problem: When I create a build and deploy it on a GL fleet, the server app fails to start the Fusion server with the following error: EntryPointNotFoundException: nanosockets_address_set_ip Of course, I've asked Photon for support first. They said that this error means that either the nanosocket .dlls are missing from my build or the executable can't access them. Since both .dlls are present in the correct locations, it seems like the app just can't access them. The weird part is that they're both inside the C:\Game folder (2 or 3 levels down in subfolders, but still). From what I've read in the AWS docs, the app should be sandboxed but have access to its own folder (C:\Game). Does anyone have an idea why my app wouldn't be able to access the Fusion .dlls? My team has been stuck on this issue for days, so any help or pointers would be appreciated. Thanks in advance!

I followed the documentation for setting up CloudWatch logging on a linux fleet and used an existing script from the docs, and even sshd in and tested it all out and it works when manually inputting each command. But no matter what I do it fails to find the install.sh and fails to initialize the fleet so I can't even debug it anymore. I'm using a ue4 linux server build if that matters. A little surprised the only other reference I've found is 5 years old where the problem never seemed to be resolved.

I get the following exception during **runtime** on android: `MissingMethodException: Default constructor not found for type Amazon.Util.Internal.PlatformServices.NetworkReachability` The code below is executed: ``` var client = new AmazonGameLiftClient( "<accesskey>", "<secret>", new AmazonGameLiftConfig { UseAlternateUserAgentHeader = false, RegionEndpoint = RegionEndpoint.USEast1 } ); ``` I didn't have any issues running the game client on windows and the server running on linux.

Hi there. Is there any way to create some sort of shared game bundle and items that can be accessible across all users? Let's say I want to store the info about our game title, game season title, default round length etc. and I want to read it when launching the game using gamekit. How can it be implemented at the moment? User bundles works great and provided sample helped a lot, but it would be nice to know how can I read some sort of global game data. Thanks a lot.

Hello, atm I'm testing with just one gamesession. And if one player leaves the session, I do GameLiftServerAPI.RemovePlayerSession(playerSessionId) and the player gets the status "Completed". But then he can't join this session anymore, even so the session is still up & running. What do I have to change, that the player can join the session again? PS: My configs: * Backfill mode: Automatic * FlexMatch mode: WITH_QUEUE * Matchmaking Ruleset algorithm: { "balancedAttribute" : "skill", "strategy" : "balanced", "batchingPreference": "largestPopulation" },

Any expert that is familiar with the AI topics for QA Automation and Rendering optimization?

Does a collection of GameLift service samples exist? I'm developing a Battle Royale game in Unity using the Unity Plugin for GameLift and I have the basics functioning.. starting with CloudFormation template deployment, FlexMatch with game session queue, and automatic backfill. Now I'm starting to build a Lobby system, where a player can create/join/apply to join/invite to join other online clients. This seems like something that should exist in sample code (CloudFormation template, Lambda files, DynamoDB tables, SNS Topic Event Handlers, etc.). Does it? I may have it built and working by the time I get a response here, but here's what I'm thinking. LobbyTable LobbyId PlayerId # lobby owner TicketId # matchmaking ticket id PlayerLobbyTable PlayerId LobbyId Lambda functions to handle setting up a table items when a player: creates a lobby # creates LobbyTable item for PlayerId as owner application/invitation is accepted # creates PlayerLobbyTable item for PlayerId leaves/booted from lobby # deletes PlayerLobbyTable item of leaving PlayerId, picks new lobby owner and assigns if anyone remains in lobby or deletes LobbyTable for LobbyId if no players remain change lobby owner # changes LobbyTable PlayerId to new lobby owner update matchmaking ticket id # when FlexMatch MatchmakingSucceeded event, add IpAddress, Port, DnsName, etc. attributes to LobbyTable item, send message to all players in lobby that the matchmaking succeeded. Thank you.

AWS GameKit is now extended to support Android, iOS, and MacOS games developed with Unreal Engine. AWS GameKit, [launched on March 23, 2022](https://aws.amazon.com/about-aws/whats-new/2022/03/aws-gamekit-unreal-engine/), gives game developers a powerful tool set to quickly and easily build AWS powered game features directly from the Unreal Editor. With today's update, the AWS GameKit plugin for Unreal Engine now supports developers who are building games for Win 64, Android, iOS, and MacOS. Game developers can use the AWS GameKit plugin for Unreal Engine to integrate the following cloud-based game features: Identity and Authentication, Achievements, Game State Cloud Saving, and User Gameplay Data. With this release, these features can now be configured and packaged into games that run on mobile devices and PC. AWS GameKit includes complete solution for each game feature and an architecture design based on the [AWS Well-Architected Framework](https://aws.amazon.com/architecture/well-architected/?wa-lens-whitepapers.sort-by=item.additionalFields.sortDate&wa-lens-whitepapers.sort-order=desc). Each feature comes with an AWS CloudFormation template for the backend architecture, plugin controls to manage the backend from the Unreal Editor, and sample C++ code and Blueprint assets to help you integrate the feature into your game. AWS CloudFormation templates provision all of the AWS resources needed to power each game feature and can be set up with just a few clicks and no prior experience with AWS tools and services. After the game backend is configured, simply add cloud-based feature functionality to the game client by calling the AWS GameKit API. AWS GameKit is a powerful tool set for game developers who want to self-manage a game's cloud resources. Each feature is fully customizable and runs in the developer's AWS account. Get started fast with the core AWS GameKit solutions, and customize and extend build to meet the needs of your game. AWS GameKit provides access to the source code to give visibility into each game feature and the ability to customize. With AWS GameKit, you can deploy backend services for your game to any of 17 AWS Regions, depending on resource availability for each of the game features. These AWS Regions include: US East (Ohio, N. Virginia), US West (Oregon, N. California), Canada (Central), South America (Sao Paulo), EU (Ireland, London, Paris, Frankfurt), Europe (Stockholm), Asia Pacific (Tokyo, Seoul, Mumbai, Singapore, Sydney), Middle East (Bahrain).

I cant seem to get access to my linux gamelift instance, when I call gamelift get-instance-access from aws CLI using fleetid and instance id, i am getting timed out. This is a different experience when i do this in a windows gamelist instance. error is An error occurred (InternalServiceException) when calling the GetInstanceAccess operation (reached max retries: 2): Timeout waiting for reply Why? This is a freshly created instance, deployed a build, created a fleet, and nothing special done. following tutorials and documentations on how to access an instance fleet, everything is correct and followed on the dot, but cannot get the instance access in CLI because of the timing issue i described above.. This is getting frustrating

Is it possible to use the AWS GameKit SDK, CloudFormation templates and back end features in custom game engines?

Is the Unreal Engine plugin extensible so that a game developer can take the plugin and add to it to meet their use case to build their own backend features?

Once a GameKit feature is deployed, can game developers add additional features to the back end services within their console? For example, could you add DynamoDB Global Tables?

While setting up the Environment and Project Settings in the Unreal Plugin, can a game developer use STS tokens to get the Key, Secret and Token?

Are there plans to have iOS / Android SDK for GameSparks? Is it possible to access FlexMatch through GameSparks CloudCode? - if yes, how? - if no, then how to use FlexMatch in iOS/Android?

Hey! I've created a blank project and configured all 4 features (tested on a sample map) and wanted to package the project for windows. I've tried both develop and shipping configuration. I've followed provided packaging guide by adding GameKitConfig into Additional Non-Asset Directories to Copy (as it's been told in here https://docs.aws.amazon.com/gamekit/latest/DevGuide/awsgamekit-dg.pdf) But on packaging I'm getting following errors (they are actually differs based on what build configuration is selected.

How is AWS GameKit integrating Facebook login, does it use inbuilt browser for opening an Amazon Cognito link or using Facebook's C++ SDK? How does this work on Android?

We are in the process of testing GameLift for our game. We have created an Amazon Linux 2 VM under Virtual Box and have a working sample server form Github working and also have GameLiftLocal running on the machine. We run Gamelift running the following command: ``` [ec2-user@vm_gamelift3 GameLiftLocal-1.0.5]$ java -jar GameLiftLocal.jar ``` This seems to result in a successful startup: ``` 05:22:54,823 INFO || - [SocketIOServer] main - Session store / pubsub factory used: MemoryStoreFactory (local session store only) 05:22:59,344 WARN || - [ServerBootstrap] main - Unknown channel option 'SO_LINGER' for channel '[id: 0x88185e57]' 05:22:59,353 INFO || - [SDKConnection] main - GameLift SDK server (communicates with your game server) has started on http://localhost:5757 05:22:59,390 INFO || - [SocketIOServer] nioEventLoopGroup-2-1 - SocketIO server started at port: 5757 05:22:59,450 INFO || - [SdkWebSocketServer] WebSocketSelector-13 - WebSocket Server started on address localhost/127.0.0.1:5759 05:22:59,655 INFO || - [StandAloneServer] main - GameLift Client server (listens for GameLift client APIs) has started on http://localhost:8080 05:22:59,705 INFO || - [StandAloneServer] main - GameLift server sdk http listener has started on http://localhost:5758 ``` We also get a good connection when starting up the game server sample locally.

I'm attempting to use GameLift Custom Server FlexMatch MatchMaking Configuration with a game session placement queue. The Matchmaking Event Handler Lambda first receives a MatchmakingSearching event, then a PotentialMatchCreated event. The Game Session Queue Placements Started event shows up in the Queue metrics section, but it will then timeout (after 5 minutes). The GameLift Game Session is being created, but the instance process' OnStartGameSession(GameSession gameSession) is NOT being called.. Can someone please help me figure out how to get the OnStartGameSession to be called in the fleet instance process? Before attempting to use FlexMatch, I was able to start the placement manually and the game session was being created on the game server, and the game was playable, but I'm unable to get to that step using the automated FlexMatch matchmaking system. Thank you.

Is it safe to give my AWS account credentials to AWS GameKit in the game engine? (Access Key ID and Secret Access Key)

Does AWS GameKit integrate with OAuth 2.0? (if not, when will it be supported?)

from [this image](https://drive.google.com/file/d/1bdWuDc0BITyey8AZKKidYbgjHQsudlhT/view?usp=sharing), we can see that the game session, 53E1A6ED-EB5B-418A-89E8-D773682B70AB in the fleet fleet-76e80f57-a589-444f-ba49-664672c2f9e6 didn't call process ending before terminate the process. But when I check the logs in auxproxy.log in /local/whitewater/Logs/, [here](https://drive.google.com/file/d/1FNdQBaqWtTGv75phG0z6cXsocyA4MgX4/view?usp=sharing), we can see the game session 53E1A6ED-EB5B-418A-89E8-D773682B70AB is the process fb528fcf-ac19-45d0-9750-a28bebf4da11 in the fleet instance. But from [here](https://drive.google.com/file/d/1tBr5YfWx26eGc8I-2jbPs3GXwRqrQZx2/view?usp=sharing), we do see the it has received the process ending message for process fb528fcf-ac19-45d0-9750-a28bebf4da11. And the process is closed hundreds milliseconds after "Marking process fb528fcf-ac19-45d0-9750-a28bebf4da11 as unavailable for game sessions" log is printed. it only happens on UE5.0.1 release. Can you tell me how it determine the process closed without calling process ending? is there any other condition except process ending is called or not? thanks.

I'm not post this for this account. But if I post with newly create aws account, you guys will think I'm a beginner and ask me to increase service limit and tell me my resource usage is minimal. I have reported this issue many times since two or three months ago via email, support case and feedback, but you guys didn't realize it's actually a bug. **So please, supporter, please don't use your manual book when you see this post, just report it to the real developer team.** All newly created aws account's gamelift service limit will return 0 now in all regions and all instance types, which should be anything other than 0 (1 or 20, normally). which make all new account can't even create its first fleet. You can ask the developer team to create a new account to try and confirm it yourselves, it's very easy to reproduce.

Hi, I am wondering if there is any way that a game server can activate itself without receiving the `onStartGameSession` event? The scenario I am looking at is roughly like this: I am using a 3rd part matchmaking library; This library allows the game server starts a session and wait for the players. I am planning to make the stand-by game servers create their sessions and wait until a player connects to them; At this point I want to make a call to a GameLift api like `ActivateGameSession` to tell the GameLift the server is activated so that it adds another game server to stand-by pool. The problem I have here is that in the documentation it is mentioned that the `ActivateGameSession` should be called in response to the `onStartGameSession` event. Is the scenario I described possible to implement with the GameLift? If it is, how could I do it? Are there any caveats? Look forward to hearing from you. Regards, Aydin

REMOVEDUPLOAD as described in the title, i succesfuly made a match and used DescribeMatchmakingCommand to check on the status of a ticket, after i forced a match during my test, the status is COMPLETED, but there is no gamesession created and response.TicketList[0].GameSessionConnectionInfo is undefined. What did I do wrong and how to fix it?

Hi, --- When I attempted to create my first fleet, I got this error: "Error! Cannot create the fleet. Reason: Current limit of fleets of 0 have been reached.." I tried several ways to solve it, but failed: Change regions or reload builds doesn't work. Change Quotas of fleet doesn't work. --- Anyone can help?

When trying to create a new gamelift fleet, the following error occurs: "An error occurred (LimitExceededException) when calling the CreateFleet operation (reached max retries: 2): Current limit of fleets of 0 have been reached." This happens independently of instance type. On the service quota dashboard, the limit is 20. Does anyone have any idea on what could be causing this issue? We have been using gamelift for over a year and this is the first time anything like this has occurred.

Why can we not terminate a GameSession from the GameLift backend? Testing while setting up the GameLift features can sometimes mean that GameSessions do not shutdown from alone. GameSession costs easily pass the two digit barrier in a single day - even when just idling with no players. A feature to shutdown a GameSession is needed for developers, to help avoid costs which are not necessarily considered usual costs associated with GameLift. **What developers want and some consider a basic feature, is a free GameLift testing environment.**

Hi, I have enabled "automatic backfill" in my matchmaking configuration per the instructions in the docs: "Turn on automatic backfill" section of [https://docs.aws.amazon.com/gamelift/latest/flexmatchguide/match-backfill.html](https://docs.aws.amazon.com/gamelift/latest/flexmatchguide/match-backfill.html). The backfilling itself works well. Calls from my client service to "StartMatchmaking" will, when expected, return a match to an existing game session. The problem I'm trying to solve now is that I don't want players to be backfilled into a game that's almost over. Item #4--"Turn off automatic backfill for a game session"--doesn't seem to work when I try to implement it on my game server: > **4. Turn off automatic backfill for a game session**. You can opt to stop automatic backfill at any point during an individual game session. To stop automatic backfill, add code to your game client or game server to make the GameLift API call StopMatchmaking. This call requires a ticket ID. Use the backfill ticket ID from the latest backfill request. You can get this information from the game session matchmaking data, which is updated as described in the previous step. What confuses me here is that I want to stop backfilling near the end of the game regardless of whether the game session has backfilled any players yet. The line "Use the backfill ticket ID from the latest backfill request" doesn't make sense if no backfill tickets have been received in the game session. Intuitively, it feels like there should just be some API I can call that opts a particular game session out of future backfill requests but I'm not seeing it. Any help would be greatly appreciated.

**Hello!** I am trying to deploy the Gamelift test suite, but am getting the following error: **Current limit of fleets of 0 have been reached..** We are a video game development company and we want to deploy our games on your infrastructure. Please get in touch with us. If there is someone who can give us support in **Spanish**, it would be the best option. **Thanks.**

Hi, In order to notify gamelift that players are accepted by my server, I have to call AcceptPlayerSession with a player session id. To obtain this player session id, I am using DescribePlayerSessions with the connecting player id as parameter. 1)I am wondering whether DescribePlayerSessions is the prefered method to obtain player session ids. If not do I have other ways? 2) Am I guaranted that by the time a player connects (which means that flexmatch successfully placed the player), DescribePlayerSessions will actually return the player session id or do I have to periodically poll? To add some context, I'm using both Gamelift and Flexmatch. Thanks, Nicolas.

I tried it earlier and there are a few errors I am planning on working through but was wondering if anyone else has already done this?

Hello! Whenever I attempt to create a new fleet, I get this error: `Error! Cannot create the fleet. Reason: Current limit of fleets of 0 have been reached..` Was working fine last week, and I have no fleets currently running. Any ideas?

Things were working fine last week, now whenever I try to create a fleet it gives this error: Error! Cannot create the fleet. Reason: Current limit of fleets of 0 have been reached.. I have 0 fleets, and in the limits section it says I can have up to 20. This seems to be happening to others as well. I only have 2 more days to finish my project so this is very unfortunate for me. 😦

How can I add 3P identity providers to the Identity & Auth feature on AWS GameKit?

hi. I tried to make freet, “Current limit of fleets of 0 have been reached…” I keep getting an error message. Currently, the number of fleets generated is zero. In the past, there was no problem with generating fleets several times. Is there a if process required to delete it? It's been more than 3 days since the problem lasted. Can you solve this problem on your own? thanks

Today we are releasing AWS GameKit, a new solution that allows game developers to deploy and customize game backend features directly from Unreal Engine. AWS GameKit comes with AWS CloudFormation templates for each feature that follows AWS Solution Architect designs. AWS GameKit also comes with an integration code between the game backend features and Unreal Engine. AWS GameKit is for game developers looking to build AWS-powered game features directly from Unreal Engine with just a few clicks. With this release, developers have access to four game backend features: Identity and Authentication, Achievements, Game State Cloud Saving, and User Gameplay Data. AWS GameKit uses AWS CloudFormation templates to provision and connect all the necessary AWS resources together into a cohesive solution to power these features. Each feature follows the AWS well-architected framework to provide a secure, high-performing, resilient, and efficient infrastructure deployment that is fully customizable and runs in the developer's own AWS account. AWS GameKit also provides Unreal Engine Blueprints, C++ code, libraries, documentation, and sample UIs for each of the four game features. The provided AWS CloudFormation templates automatically configure cloud resources that allows game developers to programmatically apply AWS best practices with common abstractions. This leads to the rapid creation of cloud-connected game features without being an AWS expert. AWS GameKit can be used to deploy cloud-connected game backend features in 17 AWS Regions where applicable, dependent on feature requirement of available AWS primitives: US East (Ohio, N. Virginia), US West (Oregon, N. California), Canada (Central), South America (Sao Paulo), EU (Ireland, London, Paris, Frankfurt), Europe (Stockholm), Asia Pacific (Tokyo, Seoul, Mumbai, Singapore, Sydney), Middle East (Bahrain). Learn more and download AWS GameKit from the [AWS GameKit website](https://aws.amazon.com/gamekit/) or our [GitHub Repository](https://github.com/aws/aws-gamekit-unreal/releases).

I have checked with support and confirmed this is not a payment issue. Yesterday, I was able to create new fleets in AWS Gamelift without a problem. In the past, I have gotten a similar error once I have 5 fleets, "Current limit of fleets of 5 have been reached.." Currently I have 2 active fleets, and am unable to make a third.

Hello! I'm trying to migrate my current dedicated server from playfab to gamelift, and Playfab had an event for session closing, that I could catch in cloud code. I've used this to handle reconnecting of players who had some network issues/crashing. So far I've found nothing similar in gamelift. Is there a way to get an event out to lambda or SNS every time a game session closes (for any reason, ended, crashed, terminated, all need to be caught)? Thank you!

We are listening to FlexMatch notifications using SNS to Lambda and writing session info to a DynamoDB table. Our game runs on iOS through Unity and our backend exposes a REST API. We currently have the client poll our API after starting matchmaking but we want to switch to some kind of a push mechanism. What is a good AWS based solution for pushing matchmaking updates to the client? Looks like AppSync has some kind of a pub-sub tech but might require adapting to a GraphQL paradigm & writing a .NET wrapper to the AppSync iOS library. Maybe APNs with silent notifications through SNS? Is APNs reliable enough for anyone's experience?

Hello! I've started getting this error when calling aws gamelift create-game-session for GameLiftLocal `"ERROR || - [GameLiftHttpHandler] Thread-36 - No available process."` This is the full command I'm using. Previously this hasn't given me any issues: `aws gamelift create-game-session --endpoint-url http://localhost:9080 --maximum-player-session 8 --fleet-id fleet123` Any ideas why this would suddenly give me issues? Have tried restarting my PC multiple times.

based from here https://docs.aws.amazon.com/gamelift/latest/flexmatchguide/match-server.html GameLift sends an onStartGameSession() for new game session, in the matched game, is this automatically called or should the client application still have to issue create Game session command? Ive been following the code samples here: https://github.com/BatteryAcid/unity-custom-gamelift-client though it doesnt use flexmatch, it calls CreateGameSessionAsync() and in turn calls onStartGameSession in the custom gamelift server. I cant seem to find example codes in unity that uses flexmatch in client side that has a complete process from, starting/looking for match, accepting match and starting a gamesession from that match. I dont get the process and sequence in the client side and process. Anyone can recommend a good resource?

I'm having trouble with one particular piece of code that is supposed to be sending a message to a client. Both pieces of code below are from my Realtime Server Script: ``` function onPlayerAccepted(player) { logger.info("..New player accepted: " + player.peerId); const newPlayerMessage = session.newTextGameMessage(OP_CODE_PLAYER_ACCEPTED, session.getServerId(), JSON.stringify(galaxyAndLocalPlayerState)); session.sendReliableMessage(newPlayerMessage, player.peerId); } ``` The above block within my realtime server script runs when a player is accepted, and the message is successfully received by the client (Unity). On the client side, logs show that OnDataReceived() **is called**. RTS Logs for above call: 02 Mar 2022 03:59:32,191 [INFO] (ManhuntServerScript.js) 96: ..New player accepted: 1 02 Mar 2022 03:59:32,191 [INFO] (index.js) 333: Received custom game message from sender: -1 with opCode: 100, targetPeerId: 1, targetGroupId: 0 ``` function onMessage(gameMessage) { switch (gameMessage.opCode) { case OP_CODE_TRAVEL_REQUEST: logger.info("..Travel Request Received from Peer " + gameMessage.sender + " to PlanetId: " + gameMessage.getPayloadAsText()); const travelResponseMessage = session.newTextGameMessage(OP_CODE_TRAVEL_BEGIN, session.getServerId(), JSON.stringify(playerStates)); session.sendReliableMessage(travelResponseMessage, gameMessage.sender); break; default: logger.info("..Unrecognized Op Code received: " + gameMessage.opCode); break; } } ``` The above block shows the message is being sent in the server logs, but is not received by the Unity client. I have ensured the op codes match. On the client side, logs show that OnDataReceived() **is NOT called**. RTS logs for above call: 02 Mar 2022 03:59:36,628 [INFO] (index.js) 333: Received custom game message from sender: 1 with opCode: 200, targetPeerId: -1, targetGroupId: 0 02 Mar 2022 03:59:36,628 [INFO] (ManhuntServerScript.js) 136: ..Travel Request Received from Peer 1 to PlanetId: 2 02 Mar 2022 03:59:36,629 [INFO] (index.js) 333: Received custom game message from sender: -1 with opCode: 102, targetPeerId: 1, targetGroupId: 0 --- The only thing I can think of is that possibly a realtime server can't send a message within onMessage() but that seems silly to me. Thanks in advance for any insight!

Arent all multiplayer game realtime? im going thru all the "getting started" documents and tutorials but I cant grasps the difference between the two Custom game servers https://docs.aws.amazon.com/gamelift/latest/developerguide/gamelift-integration.html Realtime game servers https://docs.aws.amazon.com/gamelift/latest/developerguide/realtime-plan.html

Hello everyone, I've been a software and game developer for well over a decade, and I feel very at home with C, C++ and C#/.NET. I've done a lot of programming with DirectX SDKs and Unity, as well as desktop and mobile development. However, I don't really know much at all about the web and networking. But now I'm becoming very interested in what kinds of things I can do with AWS in game development, as well as with blockchain, AI/ML and cloud computing power. There seems to be more AWS services and packages than I can count though, and I'm really not sure which ones I should be pursuing and trying to learn more about and which ones are irrelevant to me and my job. The list of services, SDKs and packages is as impressive and inspiring as it is overwhelming and confusing! I'd like to be able to deploy some .NET applications to AWS to provide remote APIs for games and applications. To start with and get the hang of it, I just want to make a little minigame that lives on a server that a Unity or Unreal game can interact with through http requests. And I'll incrementally add some features to it as I start to get the hang of it. I'd also like to do some experimentation with blockchain software and services and see what kinds of interesting things can be accomplished with it. And beyond that, I'd eventually like to get into using AI/ML to accomplish goals in games and apps, harness cloud-based CPU/GPU processing power for heavy-lifting and even setup some real-time multiplayer game servers. I just don't know what tools/services/packages I need to dive into and start figuring out. I've found [the Visual Studio 2022 AWS package here](https://marketplace.visualstudio.com/items?itemName=AmazonWebServices.AWSToolkitforVisualStudio2022&ssr=false#overview), as well as [this AWS GitHub page](https://github.com/aws/dotnet) for .NET. I've also heard about Lambda. I really have no idea which ones are relevant to me or where I should start with this. To begin with, I want to run a .NET application on a server that applications can query and interact with and have it store and supply data for them, offer some remote APIs and requests, etc. I'd also potentially be interested in running some native C/C++ modules on servers. Can someone point me in the right direction and tell me what I need to set up and dive into first? I'm doing this in my free time when I'm not working on projects for work, so my time is very limited and researching and learning the wrong things would be a big setback for me. Any help or guidance is greatly appreciated!

Hi, The documentation for backfill implies that it is useful for starting sessions with less than idea number of players and then ramping up to more players as the session goes on. It's unclear how this is accomplished when using Flexmatch in Standalone mode at the moment. Suppose a situation where I have three tickets in the pool. The ruleset specifies that a match's team (for the sake of argument we'll say there is only one team here) can have between five and ten players. Ticket A has 3 players. Tickets B and C have 2 players. The expected outcome is that A, B and C can all fit into a match. Given the ruleset, it's not unexpected that only A and B make it in on the regular matchmaking process, leaving C out. If I submit this match back into the pool as a backfill, my expectation is that C then makes it in, as that would put the match count to 7, which is within the range. However, what I've observed in test is that C never gets in. It seems like, because the session is valid (5-10 players, five are in), Flexmatch never considers adding C to it. I'm wondering if this is a limitation of Flexmatch in Standalone mode? Thanks, Hannah

I can remote into my server, see that the logs exist there, but when I try to use the CLI Console to download the logs at locations /local/game/GameName/Saved/Logs/GameName.log it tells me it cannot be found. Any ideas?

We are using the following matchmaking ruleset with a standalone configuration ``` { "name": "MatchmakingRuleset", "ruleLanguageVersion": "1.0", "algorithm": { "backfillPriority": "high", "batchingPreference": "random", "strategy": "exhaustiveSearch" }, "playerAttributes": [ { "name": "tournamentDefinitionID", "type": "string" }, { "name": "skill", "type": "number", "default": 0 } ], "teams": [ { "name": "player", "minPlayers": 0, "maxPlayers": 1, "quantity": 4 } ], "rules": [ { "name": "SameTournament", "description": "Match players to play in the same tournament type", "type": "comparison", "operation": "=", "measurements": ["flatten(teams[*].players.attributes[tournamentDefinitionID])"] } ] } ``` Since minPlayers is 0 for all teams, that means that when there are no other players matchmaking at the moment and no backfilling tickets, players can get a successful match with just their own ticket, in which event we create a new game, and the player enters this game alone. We then call startMatchBackfill with the same configuration and repeat the process until the game is full. This mean that at any given moment, any submitted ticket "should" always result in a MatchmakingSucceeded callback, so theoretically there should be no waiting for matchmaking. For some reason we are experiencing wait times of 5-10 seconds from when we call startMatchmaking until our matchmaking event listener lambda is called (wired through EventBridge), is there any way to speed this up? Is this a technical constraint? Is FlexMatch waiting for more tickets to enter the pool, and is there a way to configure this?

Hi, After an unfortunately long time trying to debug why my rules were not working on Flexmatch, I discovered that Rule validation doesn't spot if you mistype a measurement. I.e. if you mistype **"measurements": ["flatten(teams[*].players.attributes[gameMode])"]** as **"measurements": ["flatten(teams[*].players.attributes[gameMode]"]** (note the missing closing bracket) then the rule will silently fail despite validation saying it's fine.

In addition to my earlier issue (see AWS Gamelift Fleet Instance Capacity not updating on terminated fleet), I'm now having an issue where I have zero builds visible, and if I upload a build it does not appear. Any ideas?

I'm testing build compatibility with the free tier for Gamelift. Deleted a fleet and am now receiving a too many instances error when I try to build another one. My fleet console shows empty, but the CLI Describe-fleet-capacity shows me as having an active fleet nor active instances.

Hello GameLift devs, Today, the GameLift team is excited to announce three updates to FlexMatch. The updates expand existing matchmaking functionality that will allow you to create more evenly matched players teams with greater precision. The three updates are as follows: * **Support for compound rules**. Today, the behavior in a FlexMatch [matchmaker rule set](https://docs.aws.amazon.com/gamelift/latest/flexmatchguide/match-rulesets.html) is that all of the rules must hold true to form a match. Effectively this means that all rules use the “AND” logical operator. With compound rules, more complex constructs are possible. FlexMatch now supports the following additional logical operators in addition to “AND”: “OR”, “NOT”, and “XOR”. * **Longer string lists**. FlexMatch allows you to pass in different [player attributes](https://docs.aws.amazon.com/cli/latest/reference/gamelift/start-matchmaking.html) to FlexMatch, e.g., numbers, strings, or a list of strings. String lists are currently limited to 10 strings. With today’s update, that limit is increased to 100. One common use case is to use the string list as a “blocklist” for players. Now, instead of blocking only 10 players, you can block up to 100. * **More flexible team selection**. FlexMatch “[property expressions](https://docs.aws.amazon.com/gamelift/latest/flexmatchguide/match-rules-reference-property-expression.html)” are used to perform logical operations with player attributes regarding team selection. Previously, they were limited to apply to one or all teams, only. With today's update, you can use property expressions to target more than one team without having to target all teams. We’re excited to see what you can do with this greater flexibility with FlexMatch rules logic. For more information, please refer to the following links. [Compound rules](https://docs.aws.amazon.com/gamelift/latest/flexmatchguide/match-rules-reference-ruletype.html) [Property expressions](https://docs.aws.amazon.com/gamelift/latest/flexmatchguide/match-rules-reference-property-expression.html) [API reference for string list attribute](https://docs.aws.amazon.com/gamelift/latest/apireference/API_AttributeValue.html#gamelift-Type-AttributeValue-SL) Mark Choi, GameLift PM

Hey! My server listens on 2 ports and uses port 7777 for client connection and port 7787 for beacon connection. When starting a game session, if any of these ports are busy, IpNetDriver increments the port numbers and starts listening. This could be, for example, "7778 and 7788" or "7780 and 7791". There are no dependencies. The beacon client can only connect to the expected beacon port, but it changes every new game session. Is there a way to get the gaming session beacon port together with the server's IP and port as a search result?

Hi everyone, I want to create some matchmaking request thar will include players from local network. Did somebody did that, or have some ideas how to do that.

I'm still quite new to gamelift services and spending considerable time testing and learning at my own pace. I'd like to use my free tier hours for this learning stage but if I leave a fleet running for hours during which I'm not tinkering around, it would basically be eating away at those free hours... is there a way to avoid this without having to wait for a fleet to activate every time I want to do some actual online testing (not using gamelift local)? So far I tried to create a fleet of type spot and manually set the instances to 0, however I could still log into game sessions from the client. I think it had to do with having protection set to "full" but I wanted to get some solid direction on here before I get to trying this again. If anyone can point me in the right direction I would appreciate it, perhaps there is an easier way through CLI commands as well?

I have a Java Client I am attempting to integrate with GameLift. I am able to use it to search for Active Fleets, Search Game Sessions, Create Game Sessions and Create Player Sessions. I do not know where to go from there. What API or Java method is used to communicate with the Server. I have the example Server setup and running. The example server code is shown here: https://docs.aws.amazon.com/gamelift/latest/developerguide/realtime-script.html The Java code I have written: //////////////////////////////////////// AmazonGameLift gameLift = AmazonGameLiftClientBuilder.standard() .withCredentials(new AWSStaticCredentialsProvider(credentials)) .withRegion("us-east-2") .build(); DescribeFleetAttributesRequest dfar = new DescribeFleetAttributesRequest(); DescribeFleetAttributesResult describeFleetResult = gameLift.describeFleetAttributes(dfar); CreateGameSessionRequest cgsRequest = new CreateGameSessionRequest().withFleetId(describeFleetResult.getFleetAttributes().get(0).getFleetId()) .withName("Sim Game") .withMaximumPlayerSessionCount(MAX_PLAYERS); CreateGameSessionResult cgsResult = this.gameLift.createGameSession(cgsRequest); byte[] array = new byte[[PLAYER_ID_LENGTH]]; // length is bounded by PLAYER_ID_LENGTH new Random().nextBytes(array); String playerID = new String(array, Charset.forName("UTF-8")); CreatePlayerSessionRequest cpsRequest = new CreatePlayerSessionRequest().withGameSessionId(cgsResult.getGameSession().getGameSessionId()) .withPlayerId(playerID); CreatePlayerSessionResult cpsResult = this.gameLift.createPlayerSession(cpsRequest); //////////////////////////////////////////////////////////////////////////////////////// I am assuming there is a way to communicate using to the Server using some call to cpsResult. My theory is to use cpsResult.getPlayerSession().marshal() But I do not understand how to use the marshall function. void marshall(ProtocolMarshaller protocolMarshaller) I am also not sure that is even the correct function to use. If anyone can point me in the right direction to start attempting Server communication I would be very grateful.

The GameLift Reference guide shows information on actions available using the C# SDK. It shows methods for "NewMessage" and "SendMessage". I am building my client with Java, and I can't seem to find any equivalent function in Java to send a message to the Server from the Client. Does anyone know what the equivalent methods in Java are for sending messages to a RealTime server? Thank you. https://docs.aws.amazon.com/gamelift/latest/developerguide/realtime-sdk-csharp-ref-actions.html

Hi guys, good morning! I'm having a problem and I'm confused... When I'm trying to connect two users in a dedicated server from my build project, the message sended from amazon is this: REMOVEDUPLOAD However, after a few seconds, it returns me to the join the game screen instead of traveling to the third person example map. REMOVEDUPLOAD I went to the virtual machine to see the logs and this is what returns it... REMOVEDUPLOAD When I made all this sequence, my game sessions are created, so I have to delete modifying scaling parameters of my fleet REMOVEDUPLOAD Btw, you look that? 2 player sessions has been created and can't use them... I don't understand what's happening...

Hello!) I have an issue with client/server connection. I created a game session, reserved a player session, got the URL for a client. But when the UE4 client calls ClientTravel("ip+port+?+PlayerSessionId=...), the server's game mode doesn't fire either Login() or PreLogin() functions. Because of that, I can't get a PlayerSessionId from the "Options" argument and validate the PlayerSesssion on the server and Gamelift closes it after 1 minute. When I run a server locally without Gamelift, "Login()" fires as expected. Gamelift health check works great in the server's game mode as well. Please help!

Is it possible to get a copy of the .proto files used by the Realtime client SDKs? I want to port the SDK to JVM, but I am having trouble decompiling the protobuf generated code from the C# SDK.

Steps to reproduce: 1. Open gamelift dashboard in us-west-1 2. Click "create fleet" 3. Populate the fleet creation fields 4. Click initialize fleet Expected: The UI loads briefly then shows provisioning details such as logs. The fleet should be visible in the list of fleets, perhaps in a provisioning state. Actual: The fleet creation UI closes and is replaced with the amazon loading icon (two arrows that form a circle, spinning). This has persisted for over an hour. I've tried different fleet details such as spot vs on-demand to no avail. There are no errors/logs present to suggest a failure. Any ideas? Thanks!

Guys, good afternoon! I wanted to know a little more about all this architecture to close some ideas and I have some (a little silly) questions that I want to ask. When you create a fleet of instances in Amazon GameLift, what does the game session represent? Is it an instance of the instances given by the fleet? And the player session? Is it another extension but given by the game session? I'm right?

I have created a game fleet for my game. In Fleet Setting, i set concurrent process to 10. REMOVEDUPLOAD Here is my game fleet status. I see that there are 4 active instances. But when client send request to create new game session, sometime i got this exception: REMOVEDUPLOAD What's the reason? I don't see anything wrong with my fleet setting. Why no active and available server processes found on my fleet? How to fix that error? Please help me beacuse my project gonna to launch into production. Thank you very much!

Hello again guys! Good Morning. I was thinking about a dedicated server manager and I want to share it. What about a dedicated server administrator? I was learning how to host a dedicated server using UE4 and Amazon Gamelift, but does Amazon have everything ready with this functionality? Because, i really don't know... I mean a manager who will create a dedicated server for a match when a player searches for a game. And he closes it when the game is over. I don't know if I'm practically recreating a wheel with this, so I wanted to ask about it. Thank you!

Hi guys! I'm starting to use Amazon GameLift with Unreal Engine, learning about dedicated servers, so I was reading documentation but I don't understand when billing starts or if I can do this practice using some free tier. So if someone with experience in Amazon GameLift billing can provide me with any information, I'll appreciate it. Thanks!

Hi - I understand there are specific events fired for certain FlexMatch matchmaking events (https://docs.aws.amazon.com/gamelift/latest/flexmatchguide/match-events.html). Is there anything fired (that we can capture through SNS, for example) when a GameLift fleet triggers a scaling event? Thanks. -Steve

Hi. According to documentation: https://docs.aws.amazon.com/gamelift/latest/developerguide/queues-best-practices.html#queues-design-spot >* When configuring priorities for a queue with Spot fleets, place cost near the top of the list. This will ensure that locations on Spot fleets will always take precedence over locations on On-Demand fleets, when available. Also: https://docs.aws.amazon.com/gamelift/latest/developerguide/tutorial-queues-spot.html > Prioritize the fleets in your queue. Fleet prioritization determines where the queue looks first when searching for available resources to host a new game session. You might choose to prioritize by Region, instance types, fleet type, and so on. When working with Spot fleets, we recommend either of the following approaches: > * If your infrastructure uses a primary Region with fleets in a second Region for back-up only, you want to prioritize fleets first by region, and then by fleet type. With this approach, all fleets in the primary Region are placed at the top of the list, with Spot fleets followed by On-Demand fleets. > * If your infrastructure uses multiple Regions equally, you want to prioritize fleets by fleet type, placing Spot fleets at the top of the list. I have a setup with 10 fleets (5 per region): 1 x On-Demand - c5.xlarge 4 x Spot - c5.xlarge, c5.2xlarge, r5.xlarge, m5.xlarge I've placed the On-Demand fleets last in the Queue and still the players are routed to those two On-Demand fleets instead of Spot ones. We are making the placements based on reported player latency. What am I missing? What is the explanation for this behavior? Thank you.

Hi there, https://docs.aws.amazon.com/gamelift/latest/developerguide/realtime-howitworks.html The RealTime Servers documentation said > Communication between a Realtime server and connected game clients uses two channels: a TCP connection for reliable delivery and a UDP channel for fast delivery. When creating messages, game clients choose which protocol to use depending on the nature of the message. Message delivery is set to UDP by default. If a UDP channel is not set up or not available, all messages are sent using TCP as a fallback. It didn't mention if the UDP is a [Reliable UDP](https://en.wikipedia.org/wiki/Reliable_User_Datagram_Protocol) implementation or not. If not, is there a plan to introduce a RUDP protocol in the future?

Hi folks, Just want to share some knowledge on how to iterate game server development quickly with a single fleet. The best practice is still to test out your server SDK integration with [GameLift Local](https://docs.aws.amazon.com/gamelift/latest/developerguide/integration-testing-local.html) first, to make sure you can successfully respond to a heartbeat. Otherwise, your fleet might go into ERROR if you deploy an untested build. However, GameLift Local is quite limited currently and doesn't support all features obtainable from Server SDK, so, sometimes it might be necessary to test in the actual GameLift EC2 environment. But there is another problem, uploading an updated build build and getting a new fleet to go ACTIVE takes a long time (20-40 minutes depending on your build) and is not viable for quick iteration. GameLift is currently working on revamping this process, in the mean time, here is a workaround: 1. Create a fleet with port 22 open. It's always a good idea to open port 22 for development, in case fleet is stuck in ACTIVATING and you cannot modify port settings until fleet is ACTIVE. Sample command: ``` aws gamelift create-fleet --region us-west-2 \ --name "TestFleet" --ec2-instance-type c5.large \ --ec2-inbound-permissions FromPort=6250,ToPort=6280,IpRange="0.0.0.0/0",Protocol=TCP FromPort=22,ToPort=22,IpRange="0.0.0.0/0",Protocol=TCP \ --build-id <build-id> \ --runtime-configuration ServerProcesses="[{LaunchPath="/local/game/gamelift-test-app",Parameters='port:6251 gameSessionLengthSeconds:10',ConcurrentExecutions=1},\ {LaunchPath="/local/game/gamelift-test-app",Parameters='port:6252 gameSessionLengthSeconds:10',ConcurrentExecutions=1}]" ``` 2. Once the fleet is ACTIVE, run the following script (you can also do this after the fleet has been ACTIVATING for a while, or is stuck in ACTIVATING, so that EC2 instance is created) ``` if [ "$#" -ne 1 ]; then echo "Usage: ./sshhost.sh fleetid" exit 1 fi FLEET_ID=$1 echo Fleet Id is $FLEET_ID aws gamelift update-fleet-****** INSTANCE_ID=$(aws gamelift describe-instances --fleet-****** echo Instance Id is $INSTANCE_ID IP_ADDRESS=$(aws gamelift describe-instances --fleet-****** echo IP Address is $IP_ADDRESS rm -rf /tmp/gamelift.pem aws gamelift get-instance-access --fleet-****** chmod 400 /tmp/gamelift.pem echo SSHING to host at $IP_ADDRESS ssh -i /tmp/gamelift.pem gl-user-remote@$IP_ADDRESS ``` 3. Run "`sudo su`" to assume the root access 4. Run "`rm -rf /local/game/``<FILES IN THE BUILD>` ” to unlink and delete the old build (it’s important to run rm instead of mv to unlink the running process, see stack overflow post: https://stackoverflow.com/questions/1712033/replacing-a-running-executable-in-linux) 5. Upload the new build to "/local/game" using SCP, sample command: ``` scp -i <path-to-gamelift.pem> <path-to-new-build> \ gl-user-remote@<ec2-ip-or-dns-name>:/local/game/<path-to-old-build> ``` 6. Run “`chown gl-user-server:gl-user ` `<FILES IN THE NEW BUILD>`” , need to use “`--resursive`” if you have directories, this will set the new files to the right permission so that the GameLift onbox process manager ("AuxProxy") can read them. 7. Run "`ps -efww | grep "sudo -H -E -u gl-user-server`” to get the running process ids 8. Run “`kill -9 ` `<PID>`” to kill the running processes, GameLift onbox process manager ("AuxProxy") will try to spin up a new process afterwards 9. Poll “`ps -efww | grep "sudo -H -E -u gl-user-server`” until a new process shows up 10. Create game sessions and connect the client to the new server build to test! 11. Repeat step 4-10 to iterate on the server builds.

Hi. I'm trying to find a way that will result in deploying a new version of GameServer (C#) without downtime and less GameLift infra management (builds, fleets, queues etc) and also to be able to support multiple GameServer (and clients) versions in parallel, without launching a new set of GameLift infra (builds, fleets, queues etc). This ideea consists in using the GameServer binary (server process) to load the required version code from a DLL. The versioned DLLs will be stored in S3 together with a JSON index file. The advantage is that for a new version I just need to upload the new DLL to S3 and update the JSON index file, then the server process will pick up the changes and do the rest. Actual flow: When the GameServer EC2 instance launches, will start the 50 processes that will check-in with GameLift as part of the InitSDK and then will wait for a GameSession/onStartGameSession. The server process gets the version DLL that should load, from GameSession data and downloads it from S3. Then, the server process runs the onStartGameSession callback function. When ready to accept player connections, the server process calls ActivateGameSession() and waits for player connections. Will this flow work? Thank you.

Hi everyone! Since GameLift has a limit of up to 50 game sessions per hardware node, I am trying to find anyway, how can I run more than 50 sessions per node (since the limit of 50 game sessions per node is a REALLY huge waste of resources for my lightweight game). The suggested way was to manage set up FleetIQ manually with EC2 machines (possibly with some built-in autoscaling mechanism). This way should work for us, except for one thing - in this case, we need to run raw binaries instead of containers. If we use simple binaries, we need to work somehow with monitoring, logging, implementing blue-green or canary deployments, and so on. All these concerns can be solved in an easier way by using containers. With the "containers" word I mean Docker container in this case. But running containers on raw EC2 instances seems like is not convenient enough: implementing things like blue-green or canary deployments is not really trivial, etc. I am thinking about the way with AWS ECS, based on EC2 instances. In this case, I can run 1 game session per container as much per node as I can. Fargate is not applicable in my case since the minimal limits for Fargate tasks are too huge for us and it will be a waste of computing resources again. My question is: Can I use GameLift with ECS at the same time? Why I want to use GameLift: it provides more robust Spot instances and these instances will be more suitable for the game. P.S. I also thought about AWS EKS with something like Agones but it's overkill for us, and managing EKS for us is too complex a task. @REDACTEDUSER

Hi Game Devs, Today, we are excited to announce an update to Amazon GameLift that increases coverage for developers and enhances seamless, low-latency gameplay experiences for players in Japan. This update adds Asia Pacific (Osaka) Region to GameLift and enables our game developer customers to place servers in their multi-region fleets closer to players’ actual regional locations in Japan with Asia Pacific (Osaka) and Asia Pacific (Tokyo) regions. We are also happy to introduce that GameLift FleetIQ now supports next-generation [AWS Graviton2 processors](https://aws.amazon.com/ec2/graviton/). You can now use Graviton2-hosted game servers, based on the Arm-based processor architecture, in FleetIQ to achieve increased performance at a lower cost when compared to the equivalent Intel-based compute options. To learn more about this update, please visit [our blog post](https://aws.amazon.com/blogs/gametech/now-available-new-asia-pacific-osaka-region-and-graviton2-support-for-amazon-gamelift/). In summary, this GameLift update will: * **Deliver lower player latency from increased global coverage.** Now with 23 regions with the launch of Osaka region, game developers can place players closest to where they are playing to ensure a smooth experience using GameLift’s multi-region fleet. * **Better performance at lower cost.** GameLift FleetIQ now supports Graviton2-powered instances, including c6g, m6g, r6g instance families. Available regions are Asia Pacific (Mumbai), Asia Pacific (Seoul), Asia Pacific (Singapore), Asia Pacific (Sydney), Asia Pacific (Tokyo), Canada (Central), Europe (Frankfurt), Europe (Ireland), Europe (London), South America (Sao Paolo), US East (N. Virginia), US East (Ohio), and US West (N. California), US West (Oregon). Best, Yi-Min GameLift Product Manager

Hi! I have problem in unity server build. Instance AmazonLinux. I use unity 2021.2. Because it's have new feature "dedicated server" target build. Settings: IL2CPP, .net framework. How can I fix this? ``` cant resolve internal call to "System.Runtime.InteropServices.Marshal::GetIUnknownForObjectInternal(object)" (tested without signature also) Your mono runtime and class libraries are out of sync. The out of sync library is: /local/game/GameServer_Data/Managed/mscorlib.dll When you update one from git you need to update, compile and install the other too. Do not report this as a bug unless you're sure you have updated correctly: you probably have a broken mono install. If you see other errors or faults after this message they are probably related and you need to fix your mono install first. cant resolve internal call to "System.Runtime.InteropServices.Marshal::GetHRForException_WinRT(System.Exception)" (tested without signature also) ```

So i created a fleet on console it shows its status as Active, Instances 1, Servers active 1 But on my Unity Client application when i call ListFleet it shows as if there's none, here's my call: ``` Debug.Log("Request fleet list"); var fleetsListRequest = new ListFleetsRequest(); var fleetListTask = _amazonGameLiftClient.ListFleetsAsync(fleetsListRequest); ListFleetsResponse __listResponse = await fleetListTask; Debug.Log("Total fleets " + __listResponse.FleetIds.Count); if(fleetListTask != null) { Debug.Log("Display fleets"); foreach (var __fleet in __listResponse.FleetIds) { Debug.Log(__fleet); } } ``` Also when i try to create a new CreateGameSession i get the expection saying that the fleetID requested for my userID does not exist. I don't know why is not finding my fleet, i checked the logedin id in a Debug.Log and it's correct, i also checked cognito console and shows the user login. Does anyone have a clue as to what might be going on?

We have a number of different accounts, A1, A2, AN, ("tiers", dev, test, live, etc) and they all contain builds and fleets, which then get instantiated in AWS managed accounts B1, B2, BN. I've tried manually assuming the fleet-****** I can get EC2 instance meta-data, so I can figure out the account ID of B1-Bx, but since I never know these up-front, I can't easily create a mapping back to A1-Ax, which makes it impossible to determine a) which role I can assume, and also b) which backend tier to connect to, without making individual builds for each tier. I tried using tags, but the instance role has no access, and I don't know if any of the build or fleets tags get applied to the EC2 anyway. If I defer things to after servers have started up, I could theoretically make a late binding from server IP to instance, but it happens a bit later than I would prefer. Cheers!

I am currently writing a server using the C# SDK. I would ideally like to retrieve the DNS Name and Port of the process before calling ProcessReady(), as there is some initialization I would to do with that information. Is this possible? Am I misunderstanding a part of the process? Thanks for the help!

We have a CloudFormation GameLift Fleet template with this multi-location setting: ``` .... "Locations": [ { "Location": "us-east-1", "LocationCapacity": { "DesiredEC2Instances": 1, "MinSize": 0, "MaxSize": 10 } }, { "Location": "us-west-2", "LocationCapacity": { "DesiredEC2Instances": 0, "MinSize": 0, "MaxSize": 10 } }, { "Location": "eu-west-1", "LocationCapacity": { "DesiredEC2Instances": 0, "MinSize": 0, "MaxSize": 10 } } ], ... ``` After stack deployment, the fleet has the correct locations and respective min/max instances, but desired instances is set to 1 for all locations. I am able to fix it in the AWS console post-deployment, but obviously this isn't ideal. Have I misunderstood how this CloudFormation property works? Or is this a known bug?

Hello GameLift devs, Today, the GameLift team is excited to announce the general availability of the GameLift Plug-in for Unity. With this update, you can use native Unity user interfaces and workflows to access GameLift APIs and deploy AWS CloudFormation templates for common gaming scenarios. The GameLift Plug-in for Unity provides everything you need to access GameLift APIs. After downloading and installing the plugin package into your Unity development environment, you can use the native plugin UI to configure their plugin settings, perform local testing of builds of their game server, and import and run a sample Unity game. The GameLift Unity plugin also includes five pre-built CloudFormation sample scenarios that you can customize for their game, making it easier to integrate GameLift with AWS. The five deployment scenarios include: * **Auth Only** - this scenario create a game backend service that performs player authentication. * **Single-Region Fleet** - this scenario creates a game backend service with a single GameLift fleet. * **Multi-Region Fleets with Queue and Custom Matchmaker** - in this scenario, GameLift queues are used in conjunction with a customer matchmaker. The custom matchmaker forms matches by taking the oldest players in the waiting pool. When there are enough players for a match, the AWS Lambda handler starts a queue placement. * **SPOT Fleets with Queue and Custom Matchmaker** - this scenario is the same as Multi-Region Fleets with Queue and Custom Matchmaker except it configures three fleets. Two of the fleets are SPOT fleets containing nuanced instance types. * **FlexMatch** - this scenario uses GameLift FlexMatch, a customizable matchmaking service for multiplayer games. You can deploy these five scenarios from the GameLift Plug-in for Unity. Get stated now by visiting our GitHub page: https://github.com/aws/amazon-gamelift-plugin-unity. For more information, please refer to our [Release Notes](https://docs.aws.amazon.com/gamelift/latest/developerguide/release-notes.html#release-notes-summary) and [What’s New](https://aws.amazon.com/about-aws/whats-new/2021/09/aws-amazon-gamelift-plug-in-aws-cloudformation-templates-unity/) post.

I'm making multiplayer game using Unity Mirror and GameLift. I have uploaded my build, create gamefleet, create queue and want to create game session using StartGameSessionPlacementAsync method. In the documentation, I have to set up event notification for game session placement. ( link: https://docs.amazonaws.cn/en_us/gamelift/latest/developerguide/queue-notification.html ) so following this guide, I have set up an SNS topic. But then? How my unity client subscribe to that topic and get notification when game session placement state is changed to FULFILLED ? I can't find any tutorial about that. Please help me! Thank you very much!
