Creating a server application

Let's create a new server application. Upon receiving any message, it will simply get an echo, a confirmation that it has received the message (an acknowledgement).

Creating a class library

Create a new class library project called PhotonAckServer. I have put mine in the src-server directory.

Now, we'll add three references to our project. These can be found in the libs directory of the Photon Server:

• ExitGamesLibs.dll

• Photon.SocketServer.dll

• PhotonHostRuntimeInterfaces.dll

With these added, create a new PhotonAckServer class. This will inherit from ApplicationBase, code for the same is as follows:

using Photon.SocketServer;

public class PhotonAckServer : ApplicationBase
{
  protected override PeerBase CreatePeer( InitRequest initRequest )
  {
  }

  protected override void Setup()
  {
  }

  protected override void TearDown()
  {
  }
}

And we'll also create a new PhotonAckPeer class as follows:

using Photon.SocketServer;
using PhotonHostRuntimeInterfaces;

class...
