How to create an HUD in a multiplayer game?

[feuef]

@jwatte

The PlayerController class runs for the local player on the player’s machine, and for every player on the server.

Ok I know that

@jwatte

However, the server doesn’t have a GUI.

​​​​But the host do right? I mean if the server is hosted by a player, this player have an GUI right? (also, GUI = HUD no?)

@jwatte

So, the right thing to do is to set up the HUD class to a user widget blueprint of your choice.

So in the HUD, I do the following? (see the picture)

@jwatte

In the HUD, the Player Controller will be that of the local player, on the local player’s machine.
Cast the player controller to your player controller class, and use that to read out things like hitpoints or whatnot.

I don’t get this part sorry if you can explain it differently ^^

@jwatte

It’s important to realize that you should remove all input key controls from the player pawn/character class. Instead, just have input variables for “amount of running” and “amount of turning” and such, and update the movement component inputs inside Tick(), rather than on controller input events. Move all the controller input event stuff to the Player Controller.
Without the clear Pawn / Controller distinction, you’ll be fighting the networking system and the already-existing systems for the engine, instead of benefitting from them.

Oh ok, thanks for the advice
