What is, how to?

We worked on building a roguelike game where we print a board and there's a character that can move around on it.

To run it, do ruby rogue.rb

Works on Windows and Mac at least!

Notes

To do

• ~game board - 2d grid
• ~character that can move in cardinal directions
• ~treasures
• obstacles
• scrolling map
• some way to win
• status display

Design

layering discussion: n-tier design

• data (bank accounts or board & player position)
• logic - check the data to see if you're allowed to/what should happen next (can I create a transaction? or can I go to this cell in this game?)
  • translates user actions into data changes - makes decisions about what's allowed/how
  • prepares data for presentation layer
• display - doesn't make decisions, just input/outputs (check out this transaction or print out the board game state)
  • does make decisions about how the display looks

What responsibilities go where?

• data:
  • board (where gold is, where walls are, what kind of terrrain is in each square)
  • character (current position, stats like health/#gold pieces)
• logic layer:
  • check with board: can the character move to a new position? update the character's position, update the board as needed, update character's stats as needed
  • move all the monsters
• presentation layer:
  • ask for initial setup
  • event loop
  • asks logic layer for data to print -
    • in this position, what kind of terrain should I print?
    • in this position, is the character there? - what is the character's current position?
  • accepts input to pass to logic layer
