You can replicate events by creating a custom event and setting it to replicate and then choosing which machine it runs on (server, owner’s client, or multicast)

To run on server the target must be a playercontroller or other connection owning class.  
To run on a specific client it must likewise use a specific player controller as target.  
Multicast is to the server AND all clients and works best from a gamestate.

Within the event you can run your function and it will happen on that machine.  
Events can pass parameters along just like functions can.
