In this exercise, you will create dialogue for an RPG (Role Playing Game).
To generate this dialogue define a Character
struct with a :name
, :class
, and :weapon
keys. Enforce that the :name
key must have a value.
classDiagram
class Character {
name*: string
class: string
weapon: string
}
Example solution
defmodule Character do
@enforce_keys [:name]
defstruct @enforce_keys ++ [:class, :weapon]
def introduce(character) do
"My name is #{character.name}."
end
def attack(character) do
"I attack with my #{character.weapon}!"
end
def class(character) do
"I am a #{character.class}"
end
def war_cry(character) do
"My name is #{character.name} and I am a #{character.class}!"
end
def defeat(character1, character2) do
"My name is #{character1.name} and I have defeated the #{character2.class} #{character2.name}!"
end
end
Then implement the Character
functions to generate dialogue according to the documented examples below.
defmodule Character do
@moduledoc """

%Character{name: "Frodo", weapon: nil, class: nil}

iex> %Character{name: "Frodo"}

defstruct []

Introduce the character by name.

"My name is Gimli."
iex> Character.introduce(%Character{name: "Aragorn"})

"""
def introduce(character) do

"I attack with my sword!"

def defeat(character1, character2) do

Bind three variables aragorn
, gandalf
, and gimli
to an instance of a Character
struct with the following information.
classDiagram
class aragorn {
name: "Aragorn"
class: "ranger"
weapon: "sword"
}
class gandalf {
name: "Gandalf"
class: "wizard"
weapon: "staff"
}
class gimli {
name: "Gimli"
class: "warrior"
weapon: "axe"
}
You may use these three structs to test your Character
functions.
Example solution
aragorn = %Character{name: "Aragorn", class: "ranger", weapon: "sword"}
gandalf = %Character{name: "Gandalf", class: "wizard", weapon: "staff"}
gimli = %Character{name: "Gimli", class: "warrior", weapon: "axe"}
# Example Testing
Character.introduce(aragorn)
