This is java.

Goal is to create a pacman type game. I have most of the code done just need to add in ghosts score dots etc.

Attached is the assignment, and after the assignment is my current code.

Lab 5 Now that you had a chance to create players that move on the screen, mazes, and items to collect, you are going to create a Pacman clone. You are going to use the maze from Lab 4 and recreate that maze. Then, instead of blank spaces, you are to put dots in there. You must have at least 3 levels Then, you should have a single playerthat can move through the maze collecting the dots. Feel free to use the collision detection from the first three labs or the 4th lab. You should have three lives. As you collect dots, the score should continually update on the screen. Once you collect all the dots, you should move to the next level Finally, you should have a couple of "monsters" that follow you around the screen autonomously. Remember, they are unable to move through walls. However, if they hit you, you lose a life, and the monsters should increase in speed in each level. Specifics for Lab 5: 1. Come up with a class diagram of how you would approach a system like this 2. Design an inherited structure for the affecting factors (players, monsters, dots) 3. Outline all the attributes and methods. 4. Create a Use case diagram for your program -this means, write a description of how the simulation will play out. (i.e. User starts a game, the monsters move, the user moves and collects dots, etc.) 5. Create all the stub code for your design (do not fully implement; i e. method should not do a thing). Extra Credit: Provide Power Pellets that turn the monsters into a blue monsters that can be eaten for a certain amount of time.
