need help with brick breaker (breakout)
I am completing brick breaker (breakout) as my project in computer class and I need some help in creating an Arraylist of bricks. I am also trying to figure out exactly how to create separate object classes for the bricks and maybe the paddle and balls. This is what I have. Code:
import java.applet.*;
import java.awt.*;
import java.awt.geom.*;
import java.awt.event.*;

MouseListener, MouseMotionListener

private int balls;
private int numberOfLives = 3;
private boolean gameOver;
private boolean clickStart;
//Thread controls the animation.
private Thread brickAnimator;
//delay(in milliseconds) will control the step by step
// animation time.
private int delay = 15;
private int counter = 0;
private AudioClip gameMusic;
private AudioClip gameOverMusic;
//This sets the size of the paddles and the ball and determines the
// max points for the game (a.k.a. what a player must reach to win).
