In part 1 of this series, we achieved a simple proof-of-concept for a single-player text adventure game. In part 2, we added support for multiple players, but things got considerably more difficult and foreshadowed headaches with code organization. In this article, we are going to examine more closely the nascent problems from our previous attempts, and I will share with you the code and lessons learned from crafting a terminal UI that can support real-time interactions such as chatting with other players in the game. Onward!
