Carrot, Rabbit, Wolf World in Elixir

Background

I listened to a couple different podcasts where Francesco Cesarini talked about a college programing class covering Erlang where the students were assigned a project to model a world where

1. Carrots grow on the board
2. Rabbits travel around the board, eating carrots, and reproducing
3. Wolves travel around eating rabbits and reproducing

I don't know if this is part of the story, but I also have

1. Rabbits move towards carrots nearby
2. Wolves move towards rabbits nearby

What it looks like

How to run

1. Clone the repo
2. iex -S mix
3. CarrotWorldServer.sip

And the world starts printing to the terminal.

Changing the world settings

carrot_patch.ex, rabbit.ex, wolf.ex all have settings you can change like

rabbit.ex

@carrots_in_belly_before_reproduce 1
@day_can_live_without_carrots 10

wolf.ex

@rabbits_in_belly_before_reproduce 5
@day_can_live_without_rabbits 50

carrot_patch.ex

@carrot_growth_points_required 100

Change the board size

Look for start_in_production and you can set the board_size
