Instructions

In this exercise you're playing a role-playing game named "Wizard and Warriors" with your best friends. You are the Game Master, the person tasked with making the game world come alive for the players. A key aspect of this is describing the game to the players: what is a character's status, what the town they're visiting looks like, etc.

You have five tasks that have you describe parts of the game to the players.

1. Describe a character

Each character has a class, level and number of hit points and is described as: "You're a level <LEVEL> <CLASS> with <HIT_POINTS> hit points.". Implement the (static) GameMaster.Describe method that takes a Character as its sole parameter and returns its description.

var character = new Character();
character.Class = "Wizard";
character.Level = 4;
character.HitPoints = 28;

GameMaster.Describe(character);
// => "You're a level 4 Wizard with 28 hit points."

2. Describe a destination

Each destination has a name and a number of inhabitants and is described as: "You've arrived at <NAME>, which has <INHABITANTS> inhabitants.". Implement the (static) GameMaster.Describe method that takes a Destination as its sole parameter and returns its description.

var destination = new Destination();
destination.Name = "Muros";
destination.Inhabitants = 732;

GameMaster.Describe(destination);
// => "You've arrived at Muros, which has 732 inhabitants."

3. Describe the travel method

Characters can travel to a destination using one of two options:

• Walking, described as: "You're traveling to your destination by walking."
• On horseback, described as: "You're traveling to your destination on horseback."

Implement the (static) GameMaster.Describe method that takes a TravelMethod as its sole parameter and returns its description.

GameMaster.Describe(TravelMethod.Horseback);
// => "You're traveling to your destination on horseback."

4. Describe a character traveling to a destination

When a character is traveling to a destination, this is described as a combination of the individual descriptions: "<CHARACTER> <TRAVEL_METHOD> <DESTINATION>". Implement the (static) GameMaster.Describe method that takes a Character, a Destination and a TravelMethod as its parameters and return its description.

var character = new Character();
character.Class = "Wizard";
character.Level = 4;
character.HitPoints = 28;

var destination = new Destination();
destination.Name = "Muros";
destination.Inhabitants = 732;

GameMaster.Describe(character, destination, TravelMethod.Horseback);
// => "You're a level 4 Wizard with 28 hit points. You're traveling to your destination on horseback. You've arrived at Muros, which has 732 inhabitants."

5. Describe a character traveling to a destination without specifying the travel method

In the majority of cases, characters are traveling to a destination by walking. For convenience, players are allowed to omit mentioning their travel method, in which case walking will be assumed to be the travel method. Implement the (static) GameMaster.Describe method that takes a Character and a Destination as its parameters and return its description.

var character = new Character();
character.Class = "Wizard";
character.Level = 4;
character.HitPoints = 28;

var destination = new Destination();
destination.Name = "Muros";
destination.Inhabitants = 732;

GameMaster.Describe(character, destination);
// => "You're a level 4 Wizard with 28 hit points. You're traveling to your destination by walking. You've arrived at Muros, which has 732 inhabitants."
