Hi,
I'm following Play's manual to create websockets, using actors. I got it
working that the actor "echoes" incoming messages but struggling to find
how to push arbitrary messages to it. With the synchronous version I can
store a reference to `out`:
def socket: WebSocket[String, String] =
WebSocket.acceptWithActor[String, String] { request => out =>
// can store out to send msgs to it
TmpActor.props(out)
}
But I can't do this with the asynchronous version:
def socket: WebSocket[String, String] =
WebSocket.tryAcceptWithActor[String, String] { request =>
val props = TmpActor.props _
Future(Right(props))
}
I tried adding `out` parameter like in the synchronous version but can't
get it to compile. I'm also not sure if this is the right approach to store
references to the actors. And I can't find anything to write to the socket
itself. This is to build functionality similar to a chatroom... I found
e.g. this project https://github.com/JAVEO/clustered-chat/ but still can't
find how to send a server-triggered message...
Thanks,
Ivan
