Problem solved, working code is:
GraphDSL.create(connectionActorSource) { implicit builder =>
connectionActorSource =>
import GraphDSL.Implicits._
val connectionActor = builder.materializedValue.map {
playerConnection =>
connectionManager ! ConnectionManagerActor.Register(nickname,
playerConnection)
}
val decodeFlow = builder.add(decode)
val encodeFlow = builder.add(encode)
val userActorSink =
Sink.actorRef[WsMessage](createUserActor(nickname), Logout(nickname))
connectionActor ~> Sink.ignore
decodeFlow ~> userActorSink
connectionActorSource ~> encodeFlow
FlowShape(decodeFlow.in, encodeFlow.out)
}
