Player input and events to server

Development Programming & Scripting Blueprint
1

Here’s my situation:

I have a pre-defined area where I want a player to be able to do an action. However, this action needs to come from a menu on the player’s screen. Essentially, the sequence would look like this:

  1. Player moves into area
  2. Player presses a button to bring up a UMG menu on their screen
  3. Player clicks a button on the UMG screen
  4. Action triggers(for example a light turns on)

I have the individual parts generally working, but I’m not sure how to do the replication properly between the server and the clients. I think what I need to do is this:

  1. OnComponentBeginOverlap is called on the server
  2. The player controller that caused the overlap event has a variable set, which will allow the client to pop up a UMG menu on their screen.

Is this the right way to do it? If so, how do I get the player controller of the actor that caused the overlap event?

I figured out part of the problem. In order to get the player controller from the actor that OnComponentBeginOverlap gives you, you must cast it to a Pawn object(e.g. default_soldier for some of Epic’s sample projects), and then use the ‘Get Controller’ method on that pawn in order to get the player controller.

Now that I have the UMG screen popping up on command, I need to call a method on the server. I have a reliable replicated function on the server which I was able to call before in the OnComponentBeginOverlap. I have tried calling the replicated function from the OnClick event of a UMG button, but it never replicates to the server. Any ideas?
