Description
Monster Fighter
Create a program that generates new Enemies for the user to fight. The user will attack
the enemy, and if the enemy is still alive, it will attack the user back. Keep track of the
user’s hit points (hp), if the user’s hit points reaches 0, then the game ends. Keep a count
of the number of enemies the user has slain and report that total when the game ends.
Implement the program using the following UML diagram:
Classes:
1. Enemy:
a. Has instance variables for the name and the hp.
b. Has two constructors:
i. one passes in name and hp, initialize the hp and maxHp to the
same starting value.
ii. the other one is a copy constructor for the prototype.
c. Has two get methods for name and hp.
d. Method takeDamage passes in an amount of damage to subtract from the
hp. The hp should not go below 0, if it does, set it back to 0.
e. Method attack() – returns a random amount of damage that the enemy
does. You can choose the range (ex. 1-5).
f. Method toString() – return the name and hp (ex. Orc 2/5 hp)
g. Method clone() – creates and returns a copy of the enemy by calling the
copy constructor.
2. EnemyGenerator:
a. Has an ArrayList of template enemies.
b. Constructor reads in a file (enemyList.txt) of template enemies and stores
them in the ArrayList.
i. Format of file is ‘name,maxHp’ and has one enemy per line.
c. Method generateEnemy – chooses a random enemy from the ArrayList
and creates a copy of it to return.
3. Main:
a. Create an EnemyGenerator object and integers for the user’s hp and
counter to keep track of the number of enemies slain. You can start the
user’s hp at any value you like (ex. 25).
b. Create an Enemy object and prompt the user to attack (you can include
multiple types of attacks that each do a different amount of random
damage for the user to choose from). Do a random amount of damage to
the enemy, and if the enemy’s hp is greater than 0, then it can attack back.
Repeat until the enemy’s hp is 0. Once it is 0, then increment the counter
and generate the next enemy to attack.
c. Repeat until the user quits or runs out of hp.
Notes:
1. The enemy should not be able to attack back if it doesn’t have any hp.
2. The user should not be able to attack the enemy if the user doesn’t have any hp.
3. Only generate a new enemy after the previous one is slain (ie. you’ll need an
additional loop for this).
4. You should not return an Enemy directly from the ArrayList. You should always
make a clone of it first.
a. The reason for this is that if you return one of the template enemies, and
the user does damage to it, when that enemy is chosen again later, then it
will still have 0 hp, rather than the full hp it should start with. Calling
clone will make sure that the template enemies are never touched (test this
out by not calling clone and seeing that respawned enemies have 0 hp).
5. Error check the user’s input for the menu.
