For this assignment, you will implement the class described by the UML diagram below along with a game that makes use of objects from the class.
Accept the assignment invitation from your instructor and create a new IntelliJ project from version control to clone the repository onto your computer.
Prior to the end of lab you must have the
completely implemented. The
Die class represents a die
with a specified number of sides (selected by passing an integer to
the constructor). The die must have at least two sides and no more than 100.
If a value outside of this range is attempted, the die should default to
having six sides. The current value of the die should be set to an integer
between one and the number of sides the die has, chosen at random when
the die object is constructed and whenever the
roll() method is called.
For example, for a six sided die, the current value must be set to one of
the following values with equal likelihood: 1, 2, 3, 4, 5, or 6.
The UML class diagram for the
Die class, as well as the other classes
required for your assignment, are shown below.
Your code must conform to the design specified in the UML class diagram above;
however, you may add additional attributes and methods to the classes as long
as they are declared as
private. The Git repository has starter code for
several of these classes.
Dieclass first and then move on to the
MugwumpTestclass in the
testspackage should be used to help focus your attention on the specifics of the
By building and testing each class incrementally, it will be easier build up to the final solution.
Battle Simulator 3000
The program simulates an epic battle between a Valiant Warrior (human player) and an evil Mugwump (computer player). Using rules from some generic tabletop game, the player will attempt to vanquish the evil scourge and save the kingdom.
A battle consists of a sequence of attacks which alternate between the two combatants.
Starting a Battle
Each player begins with a number of Hit Points. As long as the player has a positive number of Hit Points, they have not lost the battle.
- The Valiant Warrior uses four 10-sided dice (d10) to calculate their starting Hit Points.
- The Mugwump uses six d10 to calculate their starting Hit Points.
The battle consists of a number of attack rounds.
An Attack Round
Each attack round consists of an opportunity for each player to mount an attack (unless the second attacker is eliminated prior to their turn). To determine the first attacker for the round, both the Mugwump and the Valiant Warrior will roll a d10. Whoever rolls higher gets to attack first. In the case of a tie, both re-roll.
The attacker chooses an attack strategy and attempts to hit their opponent by rolling the die. If a hit is made, they roll the appropriate die/dice to determine the damage, and then deducts that damage from the opponent's Hit Points.
The Valiant Warrior has two possible attacks: Their Trusty Sword and their Shield of Light. The user must decide which to use in each attack.
- Their Trusty Sword hits the Mugwump on a roll of 12 or greater on a 20-sided die (d20) and rolls two 8-sided dice (d8) for damage.
- Their Shield of Light hits the Mugwump on a roll of 6 or greater on a d20 and rolls a 4-sided die (d4) for damage.
The evil Mugwump also has two possible attacks: Their Razor-Sharp Claws and their Fangs of Death.
- Their Razor-Sharp Claws hit on a roll of 13 or greater on a d20 and rolls two 6-sided dice (d6) for damage. The Mugwump uses this attack 60% of the time.
- Their Fangs of Death hit on a roll of 16 or greater on a d20 and rolls three d6 for damage. The Mugwump uses this attack 25% of the time.
If the Mugwump does not use either of their attacks, they lick their wounds and heal themself! Roll one d6 and add the result to the Mugwump's Hit Points, not exceeding their starting Hit Points.
After each attack, the attack strategy, resulting damage (or healing), and the Hit Points remaining for each combatant must be displayed.
The battle ends when one combatant's Hit Points goes to zero or below
- If the Valiant Warrior succeeds, an appropriately exultant message is displayed.
- If the Valiant Warrior fails, they are mocked by the evil Mugwump.
After each battle completes you will ask the user if they would like to battle.
- They should be able to enter any of the following to indicate yes: y, Y, yes, and Yes.
- If they do not enter any of the above, the game should exit.
Welcome to Battle Simulator 3000! The world's more low tech battle simulator! You are a Valiant Warrior defending your humble village from an evil Mugwump! Fight bravely, or the citizens of your town will be the Mugwump's dinner! You have your Trusty Sword, which deals decent damage, but can be tough to hit with sometimes. You also have your Shield of Light, which is not as strong as your sword, but is easier to deal damage with. Let the epic battle begin! Warrior HP: 29 Mugwump HP 51 The Mugwump attacks first! The Mugwump snaps at you and misses! How would you like to attack? 1. Your Trusty Sword 2. Your Shield of Light Enter choice: 1 You swing your sword and miss the foul creature! Warrior HP: 29 Mugwump HP 51 . . . Warrior HP: 2 Mugwump HP 1 The Warrior attacks first! How would you like to attack? 1. Your Trusty Sword 2. Your Shield of Light Enter choice: 2 You hit the Mugwump with your Shield of Light for 2 points of damage! The citizens cheer and invite you back to town for a feast as thanks for saving their lives (again)! Would you like to play again? (yes/no) no Thank you for playing Battle Simulator 3000!
