Displaying

The next step is to make the game display a list of heroes to the player. The actions of displaying an interface and displaying the heroes list are two different contexts. We’ll learn how to separate them. First, let’s create the heroes list by creating the heroes.ex file in the lib/dungeon_crawl folder. Our directory structure should look like this:

Let’s build the module in heroes.ex:

Press + to interact
defmodule DungeonCrawl.Heroes do 
  alias DungeonCrawl.Character
  def all, do: [ 
    %Character{
      name: "Knight",

      max_hit_points: 8,
      damage_range: 6..10,
      attack_description: "a fireball"
    },

      description: "Rogue has high variability of attack damage.", hit_points: 12,
      max_hit_points: 12,
      damage_range: 1..12,
      attack_description: "a dagger"
    }, 
  ]
end

We’ve made a list of heroes using the DungeonCrawl.Character struct. The first line of ...
