What function checks if I'm currently talking to a ref / actor?

Pretty straightforward. I'm trying to make it so that when you press "E" while in front of a specific person in New Vegas, it'll show a message instead of enter dialogue mode.

Simplest way is to put a script on that NPC with an OnActivate block. This should prevent normal activation unless you manually call the Activate function.

begin OnActivate
    if (bShowMessage)
        ShowMessage SomeMessage
    else
        Activate
    endif
end

If you don't want to modify NPC scripts, you can also use an event handler

[Ladez]

Just using an event handler isn't sufficient, the normal activation event (starting dialogue) will still occur. You have to disable interaction with the NPC first, somehow.

 

With JIP LN NVSE you can use SetInteractionDisabled.

Hello me from the past and anyone who is wanting the know the same thing currently.

 

The trick is to use the function "ObjectUnderReticle" OR "GetCrosshairRef"

set GuyInFrontOfMe to GetCrosshairRef

if iscontrolpressed 5
            GuyInFrontOfMe.StartConversation Player 00Greeted
endif

This is what I did for my mod Hire And Recruit.
