Play Framework as WebSocket client
I am using Play 2.3, checking the documentation for using Akka as a WebSocket server. However, they did not specify in the documentation whether Play can connect to existing WebSocket servers. I am mainly interested in being a WebSocket client that will receive messages from the WebSocket server. The My Play app will make a bi-directional request / response with this WebSocket server and then finally I start shutting down.
Is this possible with playing with Akka?

Not the way it is. It currently acts only as a server.
What you can do is use a client like jetty websocket from within the game itself and then process the data as you see fit.

Checkout http://backchatio.github.io/hookup/
import io.backchat.hookup._
new DefaultHookupClient(HookupClientConfig(new URI("ws://localhost:8080/thesocket"))) {
def receive = {
case Disconnected(_) ⇒
println("The websocket to " + uri.toASCIIString + " disconnected.")
case TextMessage(message) ⇒ {
println("RECV: " + message)
send("ECHO: " + message)
}
}
connect() onSuccess {
case Success ⇒
println("The websocket is connected to:"+this.uri.toASCIIString+".")
system.scheduler.schedule(0 seconds, 1 second) {
send("message " + messageCounter.incrementAndGet().toString)
}
case _ ⇒
}
}
