Question

For this project, you will be working in on the Pacman game you created for Lab 6. See the solution to Lab 6 for starting files to this project.

 

You should be working in a group of 3 or fewer students.

 

Part 1: Inheritance

Create a new class called GameCharacter.

 

Make GameCharacter a parent class of Pacman and Ghost.

 

Make sure to move all common fields and methods from Pacman and Ghost to GameCharacter.

 

 

 

Part 2: Gameplay

Begin the game with the following configuration of character placement. (How Lab #4 begins)

 

 

Allow the player to move Pacman on the board by entering the following letters to move:

W	Up
A	Left
S	Down
D	Right

You can add additional letters/keys if you would like.

When the player moves the character, you should do the following:

1.     Make sure the position they are trying to move Pacman to is valid (i.e. within the board)

·      If an invalid position is selected, ask the player to re-enter

2.     Update Pacman’s position.

3.     Randomly move the ghosts to new positions.

·      Cannot be off board

·      Cannot be where another ghost is, but can be where Pacman is

4.     Check to see if a ghost is now where Pacman is. If the ghost is where Pacman is, the game is over.

5.     Keep track of how many times the player has moved. This will be the player’s score.

 

The game should continue until the ghosts catch Pacman.

 

 

Part 3: Displaying Info to the Player

Your game should convey the following info to the player at appropriate times:

·      How to move Pacman

·      When they have selected an invalid move

·      The position of each GameCharacter after each movement.

·      When the game is over because a ghost caught Pacman

·      The player’s score (based on their moves)

 

 

You DO NOT have to display images to the player. However, if you display images to the player with a grid and the character’s in their correct position, you will get EXTREME extra credit.
