RPC problem

I'm trying to call a static member function via rpc:

Code (csharp):

1.  
2.  
3. public class QNet : MonoBehaviour
4. {
5.   [RPC]
6.   public static void SetSendRate(float sr)
7.   {Network.sendRate = sr;}
8.  
9.   void FixedUpdate()
10.   {
11.     if(state == State.Hosting  prevSendRate != Network.sendRate)
12.     {
13.     prevSendRate = Network.sendRate;
14.     networkView.RPC("QNet.SetSendRate", RPCMode.AllBuffered, Network.sendRate);        
15.     }
16.   }
17.  
18.  
19. }

But this complains that QNet sendrate does ont exist in any attached script. Any suggestions?

 

I don't think calling a static RPC will work, since the RPCs are sent to a NetworkView (addressed by the NetworkViewID) which is a specific object. So, if you need the method to be static, you could have it called from within the RPC, something like:

Code (csharp):

1. public class QNet : MonoBehavior {
2.     public static SetSendRate(float sr) { ... }
3.  
4.     [RPC()]
5.     public void RPCSetSendRate(float sr) {
6.         QNet.SetSendRate(sr);
7.     }
8. }
9.  

The QNet there is obviously optional (in particular as this is within QNet), but I think it's nice to add this there to make it obvious that this is a call to a static method (I also use this.Method and base.Method a lot because I think it makes the code more readable ... JavaScript fans might consider this insane ;-) ).

If you need the possibility to call the method "statically", i.e. someone calls that method without knowing the object, and then it's distributed via the network, I'd recommend using a Singleton pattern instead of using static methods (there's a "special Unity singleton pattern" which doesn't construct objects because that doesn't work with MonoBehaviors).

That would be the other way round then ;-)

Thank you, Jashan. I didn't need it to be static, but it didn't work the other way for some reason, and I figured a static method would be easier for the RPC to find.

I took the static out and it works!
