January 16, 2017
The second stop on our journey toward a one-room demo takes us to processing actions. In this article I built out a simple table that's used to respond to player actions based on the game state. Multi-page dialogs and default object description text were also built along the way.

I decided to focus on turning this crazy experiment into a simple one-room demo that contains all the basic mechanics of an adventure-like game. The first part of this involves supporting an arbitrary number of NPCs than can be moved between locations.

After a few iterations I have a sprite that moves around but has no place to go so it's time to try scrolling the map. Along the way I added a little more scenery and created another handy little tool.
