Amy WOD: Pokemon

Part 1: The basic WOD

For this WOD you will implement Javascript classes to represent aspects of Pokemon Go.

The first class is called “Pokemon”. It has the following fields:

• name (string, Example: “Pikachu”)
• type (string, Example: “Electric”)

The second class is called “Pokedex”. It has the following fields:

• pokemon (array of Pokemon objects).

The third class is called “Trainer”. It has the following fields:

• name (String, Example: “Amy”)
• pokedex (an instance of the pokedex object)
• caughtPokemon (array of Pokemon objects).
• level (integer)

The behaviors associated with your Pokemon Go system are:

• Constructors: Each class has its own constructor to create instances. Each pokemon is initialized with its given name and type. Each pokedex is initialized with an empty array. Each trainer is initialized with its given name and pokedex, an empty array of caughtPokemon and an initial level of 1.
• myPokedex.addPokemon(pokemon): This adds a pokemon object to the list of pokemon in the pokedex.
• myPokedex.findPokemon(“Pikachu”): This finds the pokemon with the name attribute “Pikachu” in the pokedex and returns the pokemon object. (Notice that the parameter is a String, not a Pokemon object).
• myTrainer.catchPokemon(“Pikachu”): This uses findPokemon(“Pikachu”) to add a Pikachu object to caughtPokemon. (Notice that the parameter is a String, not a Pokemon object). You can assume that the caught Pokemon will always exist in the pokedex.
• myTrainer.getLevel(): Calculates and updates the this.level field to the current level associated with this Trainer, and then returns it as an integer. Trainers start at level 1. Trainers get to an additional level for each 3 Pokemon that they catch. (Hint: use Math.floor)

Here is an example set of commands that illustrate the game so far:

const pikachu = new Pokemon("Pikachu", "Electric");
const squirtle = new Pokemon("Squirtle", "Water");
const charmander = new Pokemon("Charmander", "Fire");
const magikarp = new Pokemon("Magikarp", "Water");

const myPokedex = new Pokedex();
myPokedex.addPokemon(pikachu);
myPokedex.addPokemon(squirtle);
myPokedex.addPokemon(charmander);
myPokedex.addPokemon(magikarp);

console.log(myPokedex.findPokemon("Pikachu"));
// console prints:
//  Pokemon {name: "Pikachu", type: "Electric"}
console.log(myPokedex.findPokemon("Bulbasaur"));
// console prints:
//  Bulbasaur cannot be found in the pokedex.
const amy = new Trainer("Amy", myPokedex);
amy.catchPokemon("Pikachu");
amy.catchPokemon("Squirtle");
amy.catchPokemon("Charmander");
console.log(amy.getLevel());
// console prints:
//  You are level 2

Part 2: Let’s make this interesting

Once everyone has finished the WOD, here are some enhancements to provide more interesting behavior.

Make leveling up harder

To reach level 2, the Trainer needs at least one of each kind of Pokemon. To reach level 3, the Trainer needs at least two of each type (Electric, Water, Fire) of Pokemon. And so forth. Your code should allow Trainers to reach any level.

For example,

amy.catchPokemon("Pikachu"));
amy.catchPokemon("Pikachu"));
amy.catchPokemon("Charmander"));
amy.catchPokemon("Charmander"));
amy.catchPokemon("Squirtle"));
console.log(amy.getLevel());
// console prints:
//  You are level 2
amy.catchPokemon("Pikachu"));
console.log(amy.getLevel());
// console prints:
//  You are level 2
amy.catchPokemon("Magikarp"));
console.log(amy.getLevel());
// console prints:
//  You are level 3

Making catching a pokemon harder

Use a random number generator so that when the Trainer invokes the catch Pokemon method, it only actually results in catching a pokemon half the time. (See the FreeCodeCamp exercise on random number generation if you forgot how to use random numbers.)

amy.catchPokemon("Pikachu");
// console prints:
//  Pikachu has been caught!
amy.catchPokemon("Squirtle");
// console prints:
//  Squirtle got away!
amy.catchPokemon("Bulbasaur");
// console prints:
//  Bulbasaur has been caught!
amy.catchPokemon("Magikarp");
// console prints:
//  Magikarp got away!
