You are in a dark forest with a map and see a light north. Looking at the map is not understood. Looking around reveals a deserted field with a sharp rock. This appears to be a text-based adventure game with basic interactions like looking and moving between locations controlled by user input. The game architecture involves a main loop that asks for user input, performs the requested action, and continues until the game ends or the player dies.

185. Game architecture
WARNING: I am not an expert!

186. # not real code, don’t judge me
playing = true
while playing
ask “What do you want to do next?”
parse user input
perform action based on user input
if user dies or game ends
playing = false
end
end

187. def play
puts "Welcome to #{@map.title}"
puts "What would you like to do? (Enter 'help' to see
a list of commands)"
parse_choice(gets.chomp)
while @playing
break if !@playing
puts "What now?"
choice = gets.chomp
parse_choice(choice)
end
end

188. fn main() {
let player = player::Player::new(vec![], 1, 1);
let map = map::Map::new("Great Rust Adventure",
rooms);
let mut game = game::Game::new(player, map, true);
while game.playing {
game.play();
}

193. this might seem like a weird
simile, but…

196. Ruby is great.
Rust is great.
In different ways.
