title: How to ensure RPC was sent successfully in Photon Unity?
body: <p>I am building a multiplayer game using Photon and Unity3D engine.
  I am using photonView.RPC to send data and values between clients. But sometimes due to network problem, a sent RPC failed to execute in the clients.</p>
  
  <p>Is there any way that I can check from the client (who sent the RPC) that the RPC was sent successfully, if not, then again sent the RPC?</p>
