What's the different between SendEvent() and SendOperationResponse()?
Options
Hello
SendEvent() and SendOperationResponse() seem the same to me. And I can't find more info in Photon's doc.
I tried them in my unity3D project.
the client side
=========================================================
void Update ()
{
peer.Service();
if (!connected)
return;
if(Input.GetKeyDown(KeyCode.O))
{
var parameters = new Dictionary { { 0, "send OP please" } };
peer.OpCustom(1, parameters, true);
}
if (Input.GetKeyDown(KeyCode.E))
{
var parameters = new Dictionary { { 0, "send event please" } };
peer.OpCustom(2, parameters, true);
}
if (Input.GetKeyDown(KeyCode.D))
{
var parameters = new Dictionary { { 0, "send data please" } };
peer.OpCustom(3, parameters, true);
}
}
public void OnEvent(EventData eventData)
{
reciveCode = eventData.Code;
reciveString = (string)eventData.Parameters[1];
}
public void OnOperationResponse(OperationResponse operationResponse)
{
reciveCode = operationResponse.OperationCode;
reciveString = (string)operationResponse.Parameters[1];
}
public void DebugReturn(DebugLevel level, string message)
{
Debug.Log(level + ": " + message);
}
=========================================================
the server side
=========================================================
protected override void OnOperationRequest(OperationRequest operationRequest, SendParameters sendParameters)
{
string message = "";
if(operationRequest.OperationCode == 1)
{
message = "You said \"" + (string)operationRequest.Parameters[0] + "\"";
var response = new OperationResponse(operationRequest.OperationCode, new Dictionary { { 1, message } });
this.SendOperationResponse(response, sendParameters);
}
else if(operationRequest.OperationCode == 2)
{
message = "You said \"" + (string)operationRequest.Parameters[0] + "\"";
EventData @event = new EventData(5, new Dictionary { { 1, message } });
SendEvent(@event, sendParameters);
}
else if (operationRequest.OperationCode == 3)
{
byte[] b = { 7, 8 };
//message = "You said \"" + (string)operationRequest.Parameters[0] + "\"";
SendData(b, sendParameters);
}
}
=========================================================
My questions are
1.I can use both SendEvent() and SendOperationResponse() to send message to client. What's the different between them?
When should I use SendEvent() and when should I use SendOperationResponse()?
2.If I use SendData(), unity's will get a message "ALL: No regular operation UDP message : 7".
How to use SendData()?
Any help will be great.
Thank you.

For the most part, the SendEvent and SendOperationResponse methods are pretty similar, in that they are both designed to do roughly the same thing: send a message to the client. The difference is a little bit more to do with the design of Photon, and how it sets up a nice environment for you to work in.
Note a few basics:
- from the client, you are not able to send an event to the server. You will notice that the PhotonPeer class (of which you use to create a peer on the client-side) only has the method OpCustom, for sending messages to the server, of which sends an operation. We know this, because we can see the message being received on the server-side within the OnOperationRequest method of the PeerBase class, which you use to create a peer on the server-side.
- from the server, you are able to SendEvent and SendOperationResponse within your PeerBase class, of which you use to create a peer on the server-side.
So, from this, we can assume that the idea behind events and operations is that:
- operations tend to be initiated on the client-side, and can optionally be responded to by the server (allowing you to do a question-answer type communication)
- events tend to be initiated on the server-side, sometimes as the result of an operation initiated by the client (for example, when you send a Join operation to the server, it sends an operation response to you, and send an event to other peers)
There is a little bit more to it than that, but that should get you started.5 -
To answer your second question, SendData is mostly used internally by Photon. Personally I would suggest to avoid it as it is very unlikely you'll find a use for it within your code.5
