can't send RPC function since no connection was started

I am retrofitting my code with RPC calls and Unity isn't allowing me to call them when I'm not connected which is a problem as I am testing everything non connected. What's the work around ?

 

I'm bumping this one before I start coding around this bug/limitation ...
(aren't RPC folding back to sendmessage behavior when no network connection exist?)

 

I'm going to Necro this thread since I found it while googling solutions for a simular problem.

A simple hack I quickly came up with was to simply create a server inside the script's awake function if we're neither client or server currently.

This allows for simple non-networked scene testing of some functionality:

Code (csharp):

1. private void Awake ()
2. {
3.     // Create a fake server if we are neither client nor server so the RPC calls will function
4.     if (!(Network.isServer || Network.isClient))
5.     {
6.     Network.InitializeServer(1, 25000, false);
7.     }
8. }

 

that's a really handy tip for checking if you have a connection! thx

 

That is indeed a great tip. Certainly during development.

You're ultimately probably better to wait until the connection, with something like `OnPlayerConnected`,

but again this is a great tip especially during development. Avoids the crash in the first few seconds while everything gets connected!

 

This question asked a decade ago was for the previous networking API, not Unet.

 

Quite true Joe ! But this trick still works when you're using RPC functions in 2018 !
