Message from GameMode to Players(Controllers)

Hi. I have some problem with understanting this topic.
I have GameMode which decide when to run Warm-Up for example.
PlayerController have event with that information. How can I run this event on all clients when GameMode will decide?
I even tried to make for loop, but only server can see what happended.
Anyway thanks for help.

sounds like you don’t know about replication or RPCs.
Specifically Multicast is probably what you need to learn about.

With normal flow i don’t have problem with replication. Let me explain. I have PlayerController which has event to show information on the screen. When GameMode decide i want to run this event on every controller, but i can not setup it properly. Maybe do you have some examples how to do it?

Ok, something was wrong with the game mode set-up. I just reloaded all classes and it normal works. I am sorry for the spam. Thank you anyway.

if you need to replicate a variable or event to all clients, put it in the Game state and not in the Game mode. gamemode only concerns the server and does not replicate.
