Dialogue Plugin

is it possible for some lower level beginner tutorials for working with events and conditions? i am having a problem doing anything with the plugin as far as dialogue events go.things i want to do
when a answer is chosen (examine) do a fly around of the npc. i am guessing this will be using the sequencer but not to worried about this one currently…
the other thing is i have made my npc’s all randomly generate stats. and i have these stats displaying on a widget and i wish to show this widget for the specified npc but cant figure how to reference it from the event dialogue blueprint you instruct in tutorial for creating events… some handy small tutorials would be great to give me a idea on some things… i am only 3-4 months into unreal so excuse my lack of knowledge i am trying to learn all that i can
on another note i notice when you create a dialogue event is has considering player and npc actor nodes on override event
what are these for?
