The most advanced Pokémon game, ever.

Exercise

Implement a Pokémon game with three different Pokémon:

Pokémon
Name	Bulbasaur	Charmander	Squirtle
Type	Grass	Fire	Water
HP	100	100	100
Strength	10	10	10

• Each Pokémon has 10 points of strength, which means that when they attack another Pokémon, they deal 10 damage points.
• Each Pokémon has 100 health points.
• Some Pokémon types do extra damage to other types, see chart below

Pokemon damage chart

type	Grass	Fire	Water
Grass	1x	1x	2x
Water	1x	2x	1x
Fire	2x	1x	1x

• Fire Pokémon do double damage to Grass Pokémon
• Water Pokémon do double to Fire Pokémon
• Grass Pokémon do double damage on Water Pokémon

Game rules

This Pokémon game can be played in Ruby, based on the following instruction:

• Each Pokémon is created by instantiating a class with the type of Pokémon (eg, squirtle = Squirtle.new)
• To attack, a Pokémon uses its method attack on another Pokémon (eg, squirtle.attack(bulbasaur))
• You can check how many HP's are left by calling hp on a Pokémon (eg, squirtle.hp)
• When a Pokémon is KO'd, its HP's stay at 0, they can't be negative.

squirtle = Squirtle.new
squirtle.hp
# => 100

bulbasaur = Bulbasaur.new
bulbasaur.hp = 100

squirtle.attack(bulbasaur)

bulbasaur.hp
# => 90
squirtle.hp
# => 100

bulbasaur.attack(squirtle)

bulbasaur.hp
# => 90
squirtle.hp
# => 80

How would you implement this?

You may run rspec in the root of this directory to run a basic test suite that will verify that your game respects the rules.
