Hi,
can you explain what you mean by "asnchronous"?
usually, you want to synchronize PlayMaker variables synchronously, so that the value is the same on all machines.
sending RPC events will only provide a communication system for granular data, I don't recomand using RPC events to continously send information, for this, prefer synchronizing variables.
So, if you could explain your use case, I'll be able to point you in the right direction hopefully.
Bye,
Jean
