mattmawhinney / ContinentSize.rb
Created June 13, 2013 14:38
A paired down method for figuring out the size of a continent inspired by the game Civilization III. This is borrowed almost verbatim from "Learn to Program 2.0" by Chris Pine. It just contains a small addition that prevents the program from crashing when counting 'tiles' that are at the 'edge of the world'.
# Method from Chris Pine for figuring out
# continent size in Civilization III
# with added return conditional for spots at the 'edge of the earth'
M = 'land'
o = 'water'
world = [[M,o,o,o,o,o,o,o,o,o,o],
[M,o,o,o,M,M,o,o,o,o,o],
