Hack-n-Slash (python) ported to Ruby !

Question

Here is the code I ported to play this game from the python Object Oriented Programming course. Hope it is useful.

module Combat

    def combat_initialize
        @atk_limit = 8
        @dodge_limit = 5
    end        

    def dodge
        roll = rand(1..@dodge_limit)
        return true if roll > 4
        return false
    end

    def attack
        roll = rand(1..@atk_limit)
        return true if roll > 4
        return false
    end

end

require "./Combat.rb"

COLORS = ["yellow", "green", "red", "blue"]

module Monster
    include Combat
    attr_accessor :hitpoints, :experience, :name

    def monster_initialize
        @min_hitpoints ||= 1
        @max_hitpoints ||= 1
        @min_exp ||= 1
        @max_exp ||= 1
        @weapon ||= "sword"
        @sound ||= "roar"
        @name = self.class

        @hitpoints = rand(@min_hitpoints..@max_hitpoints)
        @experience = rand(@min_exp..@max_exp)
        @color = COLORS.sample

        combat_initialize
    end

    def to_s
        "#{@color.capitalize} #{self.class}, HP: #{@hitpoints}, XP: #{@experience}"
    end

    def battlecry
        "#{@sound.upcase}!"
    end

end

class Goblin
    include Monster

    def initialize
        @max_hitpoints = 3
        @max_exp = 3
        @sound = "groar"
        monster_initialize
    end
end

class Troll
    include Monster

    def initialize
        @min_hitpoints = 3
        @max_hitpoints = 5
        @min_exp = 2
        @max_exp = 4
        @sound = 'growl'
        monster_initialize
    end
end

class Dragon
    include Monster

    def initialize
        @min_hitpoints = 5
        @max_hitpoints = 10
        @min_exp = 4
        @max_exp = 10
        @sound = 'rooooooar'
        monster_initialize
    end
end
