I'm creating a server to host multiple game rooms, for that I have to use "rpc_id" to make calls just to the peers in a specific room like this:
for clientInLobby in clientsPerLobby[lobbyID].keys():
rpc_id(clientInLobby,"some_remote_func", some_data)
I'm worried about performance, is rpc_id an async call?, or every call waits for the peer?
Thanks.
