Ok I have three files, the first is my Pacman game (File is called Game.java), that deals with displaying the main interface of the game (pacman animation, etc). I am trying to keep track of the number of food bits remaining in the maze. So I have the second file responsible for receiving the variable FOOD_COUNTER from Game.java, and then paint the value on the screen ( This file is called Score.java). See the codes below.
Now the third file is a layout manager that uses GridBag layout, and is suppose to
add the two above files to the main interface.
The problem I have with running the files, is that when the value of the FOOD_COUNTER is updated in Game.java (ie when pacman eats a bit food in the maze), the new value is not painted to the screen in Score.java. HOWEVER, if I minimize the window and maximize it again, I see the new value of the FOOD_COUNTER painted on the screen. I can't figure out how to sort this problem. (if I try to add repaint() to the paintComponent() method in Score.java the program runs, but it slows down horribly).
Can you please help me?
Thanks
Here are the codes
This code is responsible for Pacman animation, adding the food to the maze etc.
