Your task

This project is broken up into three parts. To find out what you need to do for each part, simply search for “TODO: PART X” in the code, and replace X for what part that you are on. You should be able to run the Battle.java to have a complete battle sequence at any individual checkpoint (aka before part 1, after part 1, after part 2, or after part 3).

Some hints:

• If you ever see a comment that says {@inheritDoc}, you can hover your cursor over it to see what it means. It will make VS Code look at the interfaces and parent classes to get the appropriate documentation.
• Look at “RandomUtil.java” as it will have some really helpful methods.

Overall game description

We are implementing a battle between humans and aliens. Each battle is 4 humans vs 4 aliens in a text battle game. Each team (see HumanTeam and AlienTeam) consists of:

• Two fighters: Human fighters are called soldiers; Alien fighters are called warriors.
• One special fighter: Human special fighters are called spies; Alien special fighters are called mind warpers.
• One healer: Human healers are called medics; Alien healers are called mages.

The first team to eliminate the other team’s fighters (including special fighters) is the winner.

Class Hierarchy

Differences between Human and Alien classes

The only real difference between these two classes is that humans have a home town and aliens have a home world. The rest of the mechanics are the same.

Fighter classes: Soldier and Warrior

These classes simply have the ability to attack an opponent. Each fighter has a health value, a max health value, and an attack power. The health value must stay between 0 and their max health, inclusively. When attacking, they do a random amount of damage between half of their attack power and their full attack power. They are unable to damage the Healer classes.

SpecialFighter classes: Spy and MindWarper

These classes are like the Fighter classes above except for two main differences:

1. When attacking, they do a random amount of damage between 0 and their full attack power.
2. They have the ability to infiltrate an opponent. This means:
   • 20% of the time, the special fighter does 0 damage and is disabled (unable to do anything) for 5 turns.
   • 50% of the time, the special fighter causes the opponent to damage themselves for twice of the opponent’s attack power.
   • 30% of the time the special fighter does 0 damage

Healer classes: Medic and Mage

These classes are much different than the other classes in the game. They don’t take damage. They don’t cause damage. Each healer has two moves:

• They can heal, which heals a teammate a random number between half of their healing power and their full healing power.
• They can sacrifice, which heals a teammate to 100% health, but disables (unable to do anything) themselves for 5 turns.

Challenge questions if you finish early

• What would you change to make the characters more balanced?
• There are a couple of keywords in the code that we haven’t shown you. What are they and what do they mean?
• Create your own additional class with a different set of moves and add them to the battle.
• Explain what you like and what you don’t like about the class/interface structure and what you would change.
• Why did we use interfaces for some things and classes for other things?
