So I have been trying to create a game timer that is displayed in the UI and tells the player how much time is left and Im building it all in blue prints.
I’m not entirely sure where to put the timer so that if some one joins the game they will get the server current time left for the game so there timer will sink with everyone else.

Right now I have the timer in the player controller. I recall hearing somewhere though the player controller is not replicated? If so where should I put this timer?

Also Im not even sure if Im doing the timer correctly, how might you go about setting up a timer so that when it ends the game restarts for everyone connected to the game?

This should be pretty straightforward. You are correct, each client only has their own playercontroller.

The AGameState class is the perfect candidate for your timer. I would have the server set an int value for “time in seconds” and then set that value to replicate. All clients will get that class and that variable. Each UI can just grab the value and draw it. Leave the timer on the server and update it there.

The only drawback is replication time might make the 7…6…5 not “second accurate”, but it is good enough. You can have the client use this value and decrement it on its own timer as well for “more client side accuracy”, but still let the server overwrite it. They would compete.

You might see 7…6…7…6…5… but only in laggy circumstances. You wouldn’t be happy with a client at 0 but nothing happening either, but at least in the server authoritative way it is correct.
