Where to find a better documentation of Gamelift server SDK for Unreal Engine?

Question

UpdatePlayerSessionCreationPolicy()
Updates the current game session's ability to accept new player sessions. A game session can be set to either accept or deny all new player sessions. (See also the UpdateGameSession() action in the Amazon GameLift Service API Reference).

Syntax
FGameLiftGenericOutcome UpdatePlayerSessionCreationPolicy(EPlayerSessionCreationPolicy policy)

I wan to set "Deny" policy in my unreal engine game once game starts. But how to implement it? The documentation in the website is dubious. Where can I get some tutorial on a proper implementation?

Answer

Hi,

The Unreal Engine [UpdatePlayerSessionCreationPolicy](https://docs.aws.amazon.com/gamelift/latest/developerguide/integration-server-sdk5-unreal-actions.html#integration-server-sdk5-unreal-updateplayersessioncreationpolicy) documentation has an example of how you'd invoke this particular SDK call

```
FGameLiftGenericOutcome outcome = Aws::GameLift::Server::UpdatePlayerSessionCreationPolicy(Aws::GameLift::Model::EPlayerSessionCreationPolicy::ACCEPT_ALL);
```

In terms of when to invoke it, this would have to be custom logic within the game server itself. Once the game server has started (can be identified via the `onStartGameSession` callback) and the required players have joined, the server can invoke `UpdatePlayerSessionCreationPolicy` to prevent other players from joining. This could be built into the logic which accepts (`AcceptPlayerSession`) and reports new players to GameLift.

Alternatively, if the customer has a client backend service that is routing players to GameLift servers, it can update the  `PlayerSessionCreationPolicy ` using the [UpdateGameSession](https://docs.aws.amazon.com/gamelift/latest/apireference/API_UpdateGameSession.html#gamelift-UpdateGameSession-request-PlayerSessionCreationPolicy) API call when required.

Thanks!
