Adding a restart button, and showing score

Saucebosser

Hi there! Just a quick question. So in my game of pong, when the ball falls through, i am trying to change it so that your score is shown after the "Text" of (Your Score:). Also, underneath that, I am attempting to implement a button that asks the user if they'd like to play again. Could someone please help me out?

                 int state=0;
    import ddf.minim.*; 
    Minim minim; 
    AudioPlayer song; 
    AudioPlayer song2;
    AudioPlayer song3;

    float x, y, diameter, vx, vy, a;
    int score = 0;
    float playSong = 0;

    PFont font;

    color d = (#1BCE3A);
    boolean b1, b2, b3;
    color c1= (#1BCE3A);
    color c2 = (#1BCE3A); 
    color c3 = (#1BCE3A);



    void setup() {
      font = createFont("Harrigton-48", 48);//Title font
      font2 = createFont("ArialNarrow-48", 48);//Sound button font
      size(1300, 800);
      state = 1;
      textAlign(CENTER);
      minim = new Minim(this);
      song = minim.loadFile("stilldre.mp3");

You need a 5th screen which is a gameOver or gameWon state
