Hi, I need to send the Health variable to the HUD when it’s changed on the server. How can I do this?
The easyest way whould be to use a callback method on the replicated variable.
UPROPERTY(ReplicatedUsing=OnRep_Health) float Health; UFUNCTION() void OnRep_Health();
When the value changes server side, OnRep_Health gets called.
And you can do what you need to do when the value is updated from the server and replicated to the client.
Yes, but how can I send that variable to the player’s HUD?
Its hard for me to say with out knowing how your HUD is setup/ working.
Are you using Canvas, Slate or UMG for the HUD?
Basicly the execution chain whould go something like this.
Server Changes Health > Healt Replicated To Client > Callback method called on client > Update HUD veriable for health > Update/ Redraw HUD.
Since most of these values are extracted by the functions bound to the various HUD elements, I have found it easier to just get owning pawn, cast and get direct access to values from the HUD BP in stead…
Yes that will do it i just assumed OP was trying to do it in code.
I want to create a Widget Blueprint HUD but I don’t know how to create the widget in MyCharacter.cpp. With the blueprints I can use this:
but what I have to do in C++?
I wrote this a time back.

Let me know if something is not clear.
Visual Studio gives this error:
We really need a hand with this issue. It’s breaking our workflow
Solved. I used the function CreateWidget to create a Widget based on the Widget Blueprint.
