Looking for help on my current Java Project.

It is to create a pacman game I have most of the code done I just need help on adding the dots for the pacman to eat and then the ghosts.

Here is the program requirments

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. Then, you should have a single player that can move through the maze collecting the dots. Feel free to use the collision detection from the first three labs.

You should have 3 lives. As you collect dots, the score should continually update on the screen.

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 lose a life and the level is over after all the dots are collected.

So if anyone can help with the dots and ghosts that would be appericated.

Code follows
