In this project you are tasked with developing the basis for a text-based role-playing game. You'll be creating a hierarchy of classes which will ultimately become assets for your game.

Players should be able to choose between different character classes and then fight various monster types. Players and monsters will each have unique abilities based on their type, such as a dragon breathing fire or a wizard casting a healing spell. Each entity in the game has a number of stats as well, such as health points or attack power.

Fork this repository and clone it to your local machine. Create a new branch named develop and switch to it.

You must implement the inheritance hierarchy displayed in the image above.
Hint: Remember to Use the correct inheritance keyword for each file type. GameObject is an interface while Monster and Player are abstract classes.

Below you can find a list of all the classes you must implement. It is up to you to determine the datatype for each attribute and how to declare each method. You can add more variables, methods, and classes where you see fit.

• GameObject:
  Each entity in the game is called a Game Object. That three methods declared in this Interface are used by both monsters and players.
  
  

  • attack() is called whenever an entity wants to attack another entity (target) with their base attack power. This attack function is separate from the special abilities different classes may have.
  • takeDamage() is called whenever an entity takes damage from another one, reducing their health points by the amount of damage received.
  • die() is called when an entity's health reaches 0.
    
    

• Monster:
  Each monster must have the following attributes: health, attackPower. You can add isAlive as an attribute to keep track of a monster's current state.
  
  

  • Goblin: The Goblin class is the most basic enemy type encountered in the game. It has no unique attributes or abilities. It can only deal damage to players via basic attacks.
    
  • Dragon: The dragon monster class has the special ability to breathe fire. Using this ability damages multiple players simultaneously. You must define a fireDamage attribute to determine the fire attack's damage.
    
  • Skeleton: The Skeleton class has the unique ability to revive itself after dying (only once), resetting its health back to the full amount. One method of implementing this would be to create a deathCount attribute to keep track of its deaths.
    
    

• Player:
  Each player must have the following attributes; playerName, health, attackPower.
  
  

  • Assassin: This character class is focused on stealth and dealing critical damage, it has the unique attributes isInvisible and criticalMultiplier.
    The assassin has the ability to go invisible. Attacking while invisible breaks the invisibility but triggers a critical hit, dealing extra damage (attackPower * criticalMultiplier).
    
  • Knight: This character class focuses on damage reduction and blocking attacks. You must define the unique attribute armor. Any damage the knight receives is reduced by the amount of armor it has.
    Hint: You must override the takeDamage() method and reduce the damage done based on the knight's armor value.(Optional) The Knight can also use the ability to block incoming attacks, halving the damage received while blocking. You must define the attribute isBlocking for this purpose.
    
  • Wizard: (Optional) This character class focuses on casting spells to either damage enemies or heal allies. You must define the following unique attributes for it: mana, healSpellPower, healSpellCost, damageSpellPower, damageSpellCost
    The wizard can use mana to cast spells. Each spell has a mana cost and a power. Casting the healing spell will heal a chosen player based on the spell's power. Casting the damaging spell damages an enemy based on the spell's power. The wizard should not be able to cast spells if it doesn't have enough mana.
    
    

Pro Tip 1: Don't Repeat Yourself (DRY). Use inheritance to implement methods in the parent classes and only override them where necessary.

Pro Tip 2: Even though Monster and Player are abstract classes, you can implement methods in them. These methods can later be used or overridden by subclasses.

Pro Tip 3: Remember that you can use Super() to call the constructor of the superclass. You can use this to simplify the constructor of a child class.

Note: Every time a player or a monster performs an action, you should print the action's corresponding message in the terminal. For example, if a player uses a basic attack against a monster it could be:

Arthur attacked Dragon!
Dragon took 25 damage!
Dragon has 75 health

Use what you've learned of inheritance and polymorphism to create instances of player and monster classes and test them. You can create a list of all game objects, or a list of all players and a list of all monsters. Use App.java for this purpose. You are allowed to change all the code in this class.

Allow users to create a character and choose their class, then randomly generate monsters for the player to fight. You should also design a menu in the CLI to allow players to interact with the game. Here are a few ideas for a more complex combat system:

• Allow users to create multiple characters and send all of them (as a party) to fight monsters.
• Create new monster and character classes to diversify the combat encounters.
• Implement a dice-rolling system (like a D20) to add some elements of randomness to fights.
• Build a PvP game mode where two players can combat each other.

You are in charge of designing the game using the available tools, so get creative!

You can add more attributes to the existing classes, such as experience points, levels, gold, loot, weapons, spells, merchants, etc. Defining more complex systems might require additional interfaces and abstract classes.

Have fun & good luck :)
