Hello, I’m creating kind of role playing game, with simple mechanics but with expanded dialogues. Is in Unreal 4 engine implemented any dialogue system? Do you have any tutorial or documentation how to make for example simple conversation with npc?
See these. Maybe they will help you out. 
Thank you, second address is new for me (first one is easy to find by google). Unfortunately I have non at all experience with blueprints. Time to start learn, but I was hoping to make something based on step by step tutorial first (before learning how whole blueprints work) or at least see what UE4 is capable to do.
If you are new to Blueprint i suggest you to read this: Getting Started: Blueprint References - Blueprint Visual Scripting - Unreal Engine Forums
