hi i’m a beginner in blueprint specially networking so sorry if the question seemed dumb 
my question is … how do i call a multicast function by pressing any key on the client. i tried running the function on server but it didn’t work and it always runs it on the client only. i’m trying to make a client press a key and call a function on everyone to destroy an item. thank you.
From my mind, this is the way to do
on server, manage physical stuff, moving pawn, and so on. If your actors/pawn have replicate checkbox check, it will propagate automatically to each client.
If you want, some specific stuff running on each client like particle effect, ui, and so on, go through multicast.
