This is a very basic "Hello World" application. Click right button to see the source codes.

click here.As you can see it is very easy to communicate to the server with just 2 components. (ServerCommunication and Room)
<Communication:ServerCommunication id="client" onConnected="OnConnected(event)"
ExpansionID="TestExpansion" />
<Rooms:Room id="room" ServerComm="{client}" onRoomJoined="OnJoinedRoom(event)"
onRoomLeft="OnLeftRoom(event)" onRPC="OnRPC(event)" RoomID="HelloWorldTestRoom" />
Below you see the code where we handle some events raised by the room component.
import Lib.Communication.ParameterCollection;
import Lib.Communication.Events.RPCEvent;
import Lib.Communication.Events.RoomEvent;
import Lib.Communication.Rooms.Room;
import Lib.Communication.Events.CommunicationEvent;
import Lib.Communication.Events.ServerEvent;
protected function ApplicationComplete():void
{
this.client.Connect();
}
// Server event handlers
protected function OnConnected(event:ServerEvent):void
{
this.client.LoginUser("guest", null, null, null, null);
}
// Room event handlers
protected function OnJoinedRoom(event:RoomEvent):void
{
this.textPublic.text = event.UserName + " has joined.\n" + this.textPublic.text;
}
protected function OnLeftRoom(event:RoomEvent):void
{
this.textPublic.text = event.UserName + " has left.\n" + this.textPublic.text;
}
protected function OnRPC(event:RPCEvent):void
{
this.textPublic.text = event.RpcParameters.FetchParameterValue("userName") + " said \"Hello World\".\n" + this.textPublic.text;
}
// Button event handler
protected function btnClick():void
{
var params:ParameterCollection = new ParameterCollection();
params.AddParameter("userName", this.client.LoggedInUser.UserName);
this.room.MakeRoomRPC("HelloWorld", params);
}
Note that proper namespaces should be included in the flex application tag.
Example:
xmlns:Communication="Lib.Communication.*"
xmlns:Rooms="Lib.Communication.Rooms.*"
These will be automatically added when you start writing code and don't copy and paste it.
