I'm nearing the final development stages of my first game, but have run into a problem. I've constructed 4 different levels and allow the user to select the level they want to play from a central JPanel in a Card Layout system. My problem is that once a level is completed, I can't switch the JPanel which is displayed to start the next level, since I don't know how to access the original JPanel which acts as a driver for the other panels. Any help is appreciated, and my code is posted bellow.
