Hi, I am using metaplay with photon and i would like to cache what rooms players are in inside metaplay. I am currently using ephemeral entities and sharding by photon region. In a more traditional server setup not using akka I would probably have looked to a redis to cache this type of information. Feels like this is not required and I am wondering wether you could give me some guidance about how to implement this type of in-memory cache. I am trying to shard, have a regular c# data structure and rely on the single threading of the entity to ensure data integrity. Is this the right approach? Are there more suitable libraries I should be using? What about Entity type and replication? Should I have a write instance and then replicas? Thanks for any advice Andre

Hi everyone! We have recently stumble upon an issue in our game and I'm wondering how other people and teams handle it. tl;dr: How do you tackle config version across multiple client versions? In our case, we a few different areas that the players need to fix before progressing to the next one, each of these fixes cost an certain amount of Coins to purchase. Let's say on

Config v1

we have

table: 100 coins

, but we've done some changes and improvements and want to change

Config v2

to

table: 200 coins

. The issue is, we can't guarantee when players will update the client to get those changes. And, at the same time, we want to publish the config so the player that do update get the new values. Is there a way to make sure that older clients are served

Config v1

while they are on that client, and are only provided with

Config v2

after they update the client?

"is it possible to create in game offer or offer group that will be purchased with in game currency?" as a response it gave following

Yes, this is possible, but it depends on how you've implemented your offers.

Metaplay's offer and offer group systems are data-driven and primarily define:

what is being sold,
when it is available,
who can see it,
purchase limits,
targeting, scheduling, etc.
The framework itself does not require every offer to be purchased via an app store IAP. While the built-in cookbook focuses on real-money purchases and receipt validation, the offer system is extensible and can support other payment methods through your own game logic.

I do not see anywhere in the documentation how to change offers to not require IAP but it would be very useful to be able to utilize the system for use with in game store. Is there a way to do that? is there a guide how to do that?

Hey everyone! 👋 I've been working on enabling Google Authentication for the Google Play Store in my project. Here's what I have done so far: 1.- Added the following options to the base YAML: GooglePlayStore: EnableGoogleAuthentication: true GooglePlayOAuth2ClientCredentialsPath: "kube-secret://user-google-play-creds#creds.json" GooglePlayApplicationId: [HIDDEN] 2.- Created the necessary Kubernetes secret for user-google-play-creds. When I tested this configuration locally, everything worked perfectly, and Google Authentication showed as enabled. However, when I deployed it to the Metaplay environment, the Google Authentication does not seem to work show has disabled on the OPS panel. I'm not sure what might be going wrong here. Has anyone faced a similar issue or could point me toward what could be missing in the setup? Any suggestions would be greatly appreciated! Thanks in advance for your help! PD: I set Gamecenter too and it works without issues, but on this case looks like something related that doesn't find the Credential.

Hey! I recently got the Metaplay Production plan for our legacy project. This doesn't support Metaplay CLI. So after some consideration, I'd like to deploy the current/old server to dev/staging/prod environments as first step. So we'll have functional baseline no matter what. After that's done, I will move forward with Metaplay SDK update, as it becomes less of a risk and we can always fallback to old version for our upcoming test. However, my pipelines are running into IAM/OIDC issues. Any way to get past those so can I deploy my servers without the CLI at this time?

We want to publish a demo version (as well as the production version) on Steam to allow users to play a limited version of our game. Both versions should point to the same server environment so demo players can maintain their progress in case they choose to purchase the game later. Also they should be able to play together with friends that might have purchased the game. A demo version on Steam will get its own AppId but it seems currently only one

AppId

is supported in

SteamOptions

. Is it possible to support 2 versions currently? If not, is there any other solution than to modify the MetaplaySDK or roll our own implementation? Many thanks beforehand for any insights into this matter!

So I just have had an conversation with the metaplay documentation AI agent about that, you can see it here https://chatgpt.com/share/6992d780-7944-8007-91c3-1aead0dac03e I am not great with AI yet as you can see but what struck me is that at the end it told me to use metaplay cli; now we are already using metaplay cli to build and deploy our server images, however the gameconfig subcommand does not seem to exist so question is; is it just an AI halucynating what I would like to hear? is it in progress and lastly - maybe it should be added to CLI it would definielty make our life very much easier 🙂 we are already able to build the ocnfig archive files on our CI it is just uploading them to the environment that I need solved

What would be the best way to implement a custom analytisc for IAP if we implmemnted our store throuh Metaplay SDK - I am looking to integrate our chosen MMP sdk and other then capturing Analytics events on the client and then reinterpreting them and resending to our MMP I do not see a nice way and that seem a bit hacky

Hi, Is it possible to split the 15 sheets we have in a single google doc into 2 documents with say 10 and 5 sheets each. I'd like to separate "operational" config from game balancing and avoid potential incorrect changes. I tried adding another spreadsheet but if i try to build it it says there are missing sheets (which there clearly are as I have removed them). Thanks Andre

Hi there, We've configured our game systems to work both on Crazygames (WebGL) and mobile platforms. However, when finishing setting up Metaplay for WebGL, we've encountered an issue on redirection, as it does not work as is with Websocket. The documentation indicates to change the port server port to 9380, https://docs.metaplay.io/feature-cookbooks/unity-sdk-features/webgl doing so in the Client Compatibility Settings makes the redirection work for WebGL, but it no longer works on other platforms. What can we do to solve this? Using Websocket for all platforms seems to be the only option. EDIT: does setting "WebSockets: Enabled: true" only seems to be effective for WebGL builds

Hello, we're using Metaplay SDK 32.3 with the pre-built dashboard. It has been working so far okay, but we'd like to start building a custom dashboard now. When following these instructions (https://docs.metaplay.io/liveops-dashboard/developing-the-liveops-dashboard#getting-started), the automated initialization fails for some reason. This is the console output:

>metaplay init dashboard

Metaplay CLI 1.8.0, interactive mode

Would anyone be able to assist in this?

Hello guys! I'm wondering, do the offers support scheduling? I'm trying to implement the "Preview/Review" phases for the offers, but it seems like MetaOfferGroups.GetActiveStates is not returning the offers in these states I was able to implement only the EndingSoon state, with GetActivationEndingSoonStartsAtTime, But I didn't find any "GetActivationPreviewStartsAtTime" or so. Thanks!

Hi, After migrating to SDK v35.2 and either deploying or starting a local server, I get this error: Unhandled exception. MySqlConnector.MySqlException (0x80004005): Table 'AuditLogEvents' already exists I'll post the full log in a comment. I've followed every step of the migration process and it is revertable, but I'd like to solve this.

Hi, I'm looking at implementing a Friend request/accept flow for players to be able to connect in game. I was thinking of using the In-game mail as a way to send this type of request. When I went to the docs i realised the intention of the system is more for CRM type activity. Just wondering if you have any recommendations? Can it be used for infrequent player to player request like friendships or maybe gifting (not planned but as an example). Thanks Andre

Right after doing the SDK init from CLI, in Unity I get this compile error.

MetaplaySDK\Client\Core\Base\MetaplayCore.cs(327,17): error CS0103: The name 'Generated' does not exist in the current context

This immediately blocks following the tutorial, and any integration for that matter, I would think.

So, rather at the very beginning of the tutorial my progress halts at a roadblock. Example code has the following lines that refer to missing members (not found in inherited class or implemented interfaces (MonoBehaviour, IMetaplayLifecycleDelegate, IPlayerModelClientListener):

ConnectionEstablished?.Invoke();

await InitUnityServices();

Neither the ConnectionEstablished event, nor the InitUnityServices() method can be found anywhere in the SDK, even if I do a plain-text search through the entire solution, so this does not seem like a case of missing "using" statement (and Visual Studio would've suggested a fix for that anyway). Any help, explanation, ETA for a fix/update (of either SDK or documentation)?

Hey, we had a little bit problems when we tried to deploy staging servers. One of our PersistentEntityActors kept crashing at the start since it’s data model had changed. I had raised the server version a few times while having the NukeOnVersionMismatch flag enabled. It still didn’t work. I found a workaround but would like to understand why this happened on staging server but on dev or local server this same situation doesn’t cause any problems. Is there some differences on how database nuking works on staging vs dev servers? Here is the error when deploying:

[all-0] [16:57:43.421 ERR TeamManager] Entity TeamManager:0000000000 (status=Starting, numPendingMessages=0) crashed due to MetaWireDataTypeMismatchDeserializationException 'Failed to deserialize TeamManagerModel.BotTeam, did you change the type?

Hi, just wondering if there is a way in the client to detected which Platform I have successfully connected to. i.e. which social platform in in "Account attached" state. I can see it connected in the liveops console. I am creating a connector for Discord Social SDK. Thanks Andre

Hi, are there any plans to add support for login from the Epic Games store in the future, like with Steam?

Hey, can I report an error from SharedCode/PlayerModel in a way that is shown in the Dashboard without throwing an exception?

Hi, right now we had in our SharedCode assembly some enums and classes that were used by our gameplay too, but that means the gameplay assembly needs to reference the sharedcode/metaplay assemblies, which it makes no sense from an architecture perspective and also makes recompiling times much longer. So we though about doing a new assembly, that contains this classes and enums, and both shared code assembly and gameplay assembly reference this assembly. The issue with this is we don't have access to the required Metaplay attributes. What patterns do you recommend here? Only Idea I had is have the same 2 Enums duplicated in both assemblies and cast them, but that doesn't sound like a good approach...

Hi, I'm going through the following documentation: https://docs.metaplay.io/game-logic/how-to-guides/implementing-cheat-proof-randomization.html#overview I have some questions to understand why this is the approach that was chosen. 1. I was thinking the roll could also be ask/response type interaction. The ask handler could execute the random pcg and then invoke and action to grant the item and then return the result in the response. 2. Alternatively if we wanted a queue of unclaimed rolls we could have an entity CastMessage which requests a roll and similar to above that would populate a pending queue or results. I am wondering. What are pros and cons of using the Messaging vs executing an action with a server listener to invoke some server side logic? Thanks Andre

I would like to call an event on the ClientListener from a subclass serialized within a PlayerModel, e.g (with dumb names, sorry in advance): - I have a method that handles adding Coins (AddCoins) in a PlayerCoinsModel - Within the OnPackBoughtAction, I call player.PlayerCurrenciesModel.AddCoins(X) - I want AddCoins() to call player.ClientListener.OnCoinsAdd(amount) so that I don't have to add it manually alongside each player.PlayerCurrenciesModel.AddCoins calls. Thus, I need my subclasses to "know" their parent PlayerModel. What would be the best pattern within Metaplay constraints to that?

is there a way to append configuration signature or version from runtime build in an error log or display it on screen so that it is visible in screenshot - that would be usefull for bug reporting and debugging as well as for our internal testing to avoid confusion

Is there any way to have ScriptableObjects as GameConfig that can be published and deployed like you do with the google sheets config? Some data is easier to setup on unity with custom built tools.

Hi, how can I input the data in the google sheets so later it can get serialized/deserialized?

There is no way to know from within MetaOfferPerPlayerStateBase derived class to know what offer got its activation Finalized, No offerInfo no offer ID even is passed to the finalization. Only way to pass any other information would be to override the and pass offerId to the custom OnActivationFinalized

protected override void OnFinalizedActivation(MetaOfferGroupId groupId, IPlayerModelBase player)
        {
            MetaOfferGroupModelBase group = TryGetState(groupId);

            foreach ((MetaOfferId offerId, MetaOfferPerGroupStateBase offerPerGroup) in group.OfferStates)
            {
                if (offerPerGroup.IsIncludedInGroupActivation(group.CurrentActivationIndex))
                {
                    if (OfferStates.TryGetValue(offerId, out MetaOfferPerPlayerStateBase offerPerPlayer))
                        offerPerPlayer.OnActivationFinalized(player, group.LatestActivation.Value.EndAt.Value);
                }
            }
        }

of PlayerMetaOfferGroupsModelBase and cast

offerPerPlayer

to derived per player state type. or am I missing something?

Hi, ran into a problem where I managed to lock/corrupt my player login credentials that I was using in the Unity Editor. We're using GameConnectionDelegate.SlotOverride to get different accounts for Editor and desktop builds by default. Clearing the credentials in Unity Editor doesn't work in this case properly as the cleared credentials never take the slot into account. My suggestion is for you to change the function in CredentialsStore.cs that clears the credentials to accept the Slot string as a variable like this: /// /// Deletes stored credential for Editor. This requires no SDK init. /// public static void ClearCredentialsInEditor(string slot = "") { ClearLegacyCredentials(); ClearFileCredentials(slot); } Then we can have the control to do our own Editor script to clear whatever slot we're using inside Unity. I have now modified the source code to achieve this, but would be helpful if this made it in to a future release so I don't have to fix it every time we update the SDK in the future!

Are there any plans to add "repeat" functionality for live-ops events? I.e as soon as an event finishes a new one starts.

Hi, we are still in development and doing a lot of schema changes. We are using our production environment for playtest. We realized the MasterVersion change was not causing a db reset of production so had a hunt around in the cli and ran metaplay db reset with all the confimation flags. We have deployed the new version but the production environment is not starting and we are getting Table 'my.env.name.GlobalStates' doesn't exist. I assumed the deploy would recreate the table. Is there a way for us to recover this or do we need support for this? Thanks Andre
