I'm working on a game titled Desolate: The Rebirth and I want to have certain NPCs in the games world to have dialogue trees similar to Fallout 1 and 2 where the player can ask questions and conversate.

I am very new to the Quest system. Does anyone know how I might be able to set this up?

SHORT ANSWER = YES you can do this.

You can have multiple characters as objects that can be interacted with. You can make multiple responses to questions and swap objects with them via tasks or even questions answered etc. FLAGS are essential key words that you allocate to a character to define what response they will give to the same question.

You will be limited to :
"Ask about object or character" as your dialogue in order to provoke a response. But you can manipulate the conversations by the responses. Even a "look at character" can produce a response as well as a "ask about..." question. Also "give object to character" or "hit character" etc etc can produce a response or dialogue as you see fit.

Setup TAB :
Type : object
Name : Merlin
Type : Male character

Features TAB:
Use/Give (tick box)
Container(tick box)

Ask/Tell TAB:
Ask about ? (Have fun making "replies to questions" about objects or people etc. to this character).

*** You can use FLAGS e.g. if object "Merlin" does not have flag "riddle done": he will give different response to a question: "You have not answered my riddle". But if object "Merlin" has flag "riddle done" he may say "Well done, here is the gem stone" etc! You can also play sound effects or even put in your own small speech samples to enhance your game. But beware "THERE IS A LIMIT TO ALL SOUNDS IN MEMORY and game will be nonpunishable if you exceed the limit!"
