*   Enemy Breakout is a very simple clone of Atari 2600's Super Breakout.

*   Creating breakout is a good exercise in basic collision detection, and

*   trigonometry. The objective is simple, score as many points as you can by

*   breaking coloured bricks before all your lives run out. 

*

*   Destory all bricks to advance to the next level. Each time you clear a

*   level, you gain an extra life. I've hard-coded 5 unique stages, which do

*   repeat.  These stages are stored in the levelMaps array.  

*   

* -={ Build and Installation }

*

*   Building Enemy Breakout requires Java2 SE SDK 1.4 or greater, java.sun.com. 

*   	command: javac Breakout.java

*

* 	To play, place this inside HTML document or use appletviewer on this file:

* 		<applet code="Breakout.class" width="640"  height="480"></applet>

*

* -={ G a m e p l a y }=-

*

*   1. To begin game, click the mouse button.

*   

*   2. At the beginning of each round, you serve the ball by clicking the

*   mouse button. The serve goes straight upwards. 

*

*   3. Score points by breaking colored bricks. Green and blue bricks become

*   yellow and magenta, respectively after begin hit. So these take two hits

*   to break:

*

*            Yellow  = 1 point.  

*            Magenta = 3 points.  

*            Green   = 5 points.

*            Blue    = 7 points.

*   

*

*   4. The angle at which the ball deflects off the paddle depends where on

*   the paddle the ball touches.  The ball will also speed up every 7 hits off

*   the paddle.

*

*   5. If the ball touches the back wall ( breaks through ) the paddle will

*   shink to half size.  The paddle size will be restored next level or life.

*

*

* -={ G a m e  D e s i g n }=-

*   

*   I use a 2D integer array to represent the brick wall. There are several

*   brick types identified by integers. The wall has a maximum of 11 columns

*   and 5 rows. Each brick type has a specific color and point values. Some

*   bricks take more hits to break than others. 

*

*   I use two functions, gridToScreen() and screenToGrid() that let me convert

*   (x,y) screen coordinates to column/row indices in the array, and

*   vice-versa. I use these to determine where to draw a brick, and  when the 

*   ball is touching a brick. 

*

*   The ball will deflect at an angle that depends on which of the 8 sections 

*   of the paddle it touches.  This behavior makes the paddle appear concave.

*   These deflection angles are stored in the array deflectionAngles[] in the

*   hitBall() function. As for walls and bricks, the ball simply reflects at

*   a 45 degree angle. Like in Pong.

*

*   Oh, what else? ... yeah, BLOODY EYE-SEARING RED! Everywhere. And I'll do it

*   again, for sure.

*

* -={ F i n a l  N o t e s }=-

*

*   I originally incorporated the concept of "chaining" where you could

*   rack-up bonus points by breaking multiple bricks of the same color in a

*   row. I removed it because it gave less insentive for players to use a more

*   balanced play strategy.

*

*   The MIDI sequence, for those who want to know, is a remix of Capcom's Mega

*   Man 2, Clash Man's stage by Anthony Bellissimo <twon@ici.net> from

*   Vgmusic.com.  Vgmusic.com has a lot of MIDI's of your favorite games, made

*   by the fan community. Unfortunately, Java's default installed sound bank

*   is terrible. So one has to careful in choosing which midi sequence to use.

* 

*   I tried to make this game enjoyable, while keeping the code simple and

*   small. I also made plenty of comments so that new programmers should be

*   able to read it. 

*

*

*   Enjoy,

*
