How to use a reset button Java arkanoid game

Question

So this is part of my game panel for my game. I got my start button to work, and created a reset button but I don't know how to reset the game every single time it is pressed. Does anyone know how to reset the game to its original position after you press "Reset"? Right now it will display the words "You have died", but it doesn't do anything when I press Reset.

Thank you so much!!!

Answer 1

Right now, you have a single Listener class and two buttons that have registered against the listener (sbutton and rbutton). It'd be easier if you had different classes that implemented ActionListener, but let's move past that for now.

You need to make modifications to your actionPerformed method such that:

1. You can differentiate the source of the action - i.e. which button was pressed - Reset or the Start? Hint: use the getSource() method from ActionEvent
2. If the button pressed was the Reset button, you need to reset the GUI to its initial state
