how to send it

mad_sir1

Hi guys!
How to send a message to all players ?? I modify my server side code like this ,but it does't work:

In LiteApplication.cs :
private static readonly HashSet<PeerBase> PEER = new HashSet<PeerBase >();
public void Remove(LitePeer peer)
{
lock (PEER)
{
PEER.Remove(peer);
}
}

public void SendWorldMessage(EventData eventd)
{
lock (PEER)
{
ApplicationBase.Instance.BroadCastEvent(eventd,PEER, new SendParameters());
}
}

protected override PeerBase CreatePeer(InitRequest initRequest)
{
LitePeer peer= new LitePeer(initRequest.Protocol, initRequest.PhotonPeer);
PEER.Add (peer);//this operation I can get the all the peer connect to the photon server
return peer;
}
:?
and then In LitePeer.cs:
case OperationCode.LobbyMessageOperation:
{
LiteApplication kk = new LiteApplication();
var informa = new Dictionary<byte, object>();
informa.Add((byte)ParameterKey.lobbymessage, info);
eventdate = new EventData((byte)EventCode.LobbyMessage, informa);
kk.SendWorldMessage(eventdate);
}
break;

but I can't receive the event on the client side ,what something else I have missed ?? or anyone can give a successfull sample code ,I have confused on it many days , anyone can help me??

The problem is that you create an instance of the LiteApplication in your peer class - the instance gets disposed immediately afterwards and does not have a chance to send out the event.

You need to pass a reference to the application into your peer:

[code2=csharp]protected override PeerBase CreatePeer(InitRequest initRequest)
{
LitePeer peer= new LitePeer(initRequest.Protocol, initRequest.PhotonPeer, this);
PEER.Add (peer);//this operation I can get the all the peer connect to the photon server
return peer;
}[/code2]

... and store the "application" reference in a local variable of your peer and use that one to broadcast the event.

Thanks Nicole ,you say store the application?? but how to use a local variable to store the application ??I don't quite understand ?can you give me some example code ?? thanks !

Please get yourself a good book about C# programming and read about variables & scope. We can't give extensive support about basic programming techniques.

[code2=csharp]public class LitePeer : PeerBase
{

private LiteApplication application;

public LitePeer(IRpcProtocol rpcProtocol, IPhotonPeer nativePeer, LiteApplication app)
: base(rpcProtocol, nativePeer)
{
this.application = app;
}
}[/code2]

Oh ,NIcole ,I sorry to tell you ,your method is the same to me ,serveral days ago ,I have try it ,I am sorry that I didn't have give you the code that I have store the application , so I just want to know you how to store the application,but your method is the same to me , this method can't get the event ,and it lead a problem that when I join the room ,the logs show ERROR Lite.Room [(null)] - System.NullReferenceException: 未将对象引用设置到对象的实例。I think I should give the all code for guys ,everyone can see it ,and what is the problem?
in the LiteApplication.cs:
public static readonly HashSet<PeerBase> PEER = new HashSet<PeerBase>();
protected override PeerBase CreatePeer(InitRequest initRequest)
{
LitePeer peer= new LitePeer(initRequest.Protocol, initRequest.PhotonPeer ,this);
PEER.Add (peer);
return peer;
}

In the LItePeer.cs:
private LiteApplication yingyong;
public LitePeer(IRpcProtocol rpcProtocol, IPhotonPeer nativePeer,LiteApplication aaaaaa)
: base(rpcProtocol, nativePeer)
{
this.yingyong = aaaaaa;

}

case OperationCode.LobbyMessageOperation:
string message1 = (string)operationRequest.Parameters[(byte)ParameterKey.lobbymessage];
var info = new Dictionary<byte, object>();
info.Add((byte)ParameterKey.lobbymessage, message1);
var informa = new Dictionary<byte, object>();
informa.Add((byte)ParameterKey.lobbymessage, info);
var eventdate = new EventData((byte)EventCode.LobbyMessage, informa);
yingyong.BroadCastEvent(eventdate,LiteApplication.PEER,sendParameters);
return;
:roll:
In the LIteLobbyPeer.cs:
public LiteLobbyPeer(IRpcProtocol rpcProtocol, IPhotonPeer photonPeer)
: base(rpcProtocol, photonPeer ,new LiteApplication() )
{

} :?:
Yes these are all my code ,Nicole ,I'm sorry that I haven't give you all the code first time ,now ,this time I give the all codes, but I can't get what problem is happen ,I can't get the event, so,anyone has advice or what server side code I should modify?? :P

Your code to broadcast the event looks fine now.

I wouldn't create a new LiteApplication object in the LiteLobbyPeer constructor, just pass the LiteLobbyApplication (it inherits from LiteApplication). But that should not be the reason for any errors.

For the NullReferenceException, please attach a debugger and step through your code, or check the line number yourself. In general, if something does not work as you expect, please try to debug yourself - check if the peer lists contain the peers you expect, etc.

Hi Nicole thanks for your quickly reply!, as the code you see ,If these code:

LitePeer peer= new LitePeer(initRequest.Protocol, initRequest.PhotonPeer );
public LitePeer(IRpcProtocol rpcProtocol, IPhotonPeer nativePeer)
public LiteLobbyPeer(IRpcProtocol rpcProtocol, IPhotonPeer photonPeer)
: base(rpcProtocol, photonPeer )

then everything is ok ,but when I add these code:

LitePeer peer= new LitePeer(initRequest.Protocol, initRequest.PhotonPeer ,this);
public LitePeer(IRpcProtocol rpcProtocol, IPhotonPeer nativePeer,LiteApplication aaaaaa)
public LiteLobbyPeer(IRpcProtocol rpcProtocol, IPhotonPeer photonPeer)
: base(rpcProtocol, photonPeer ,new LiteApplication() )
then the openlogs show System.NullReferenceException: 未将对象引用设置到对象的实例。so it means that these codes have problem ,but I have debug it ,every object isn't null , maybe some where I have lost ??or any methods to modify??if I solve the problem ,I think I can broast the event!

As I said: I wouldn't create a new LiteApplication object in the LiteLobbyPeer constructor, just pass the LiteLobbyApplication (it inherits from LiteApplication).

[code2=csharp]public LiteLobbyPeer(IRpcProtocol rpcProtocol, IPhotonPeer photonPeer, LiteApplication app)
: base(rpcProtocol, photonPeer, app) { .. }[/code2]

I can't read that chinese log message, sorry, you need to debug the NullReferenceException yourself.

Thanks Nicole ,I think I should find another way to sovle this problem ,anyway,I should thank you for your help !
by the way:未将对象设置引用到对象的实例，it means Object reference not set to an instance of an object...!
