Playing some Pong!

Getting the project ready.

Make a new Eclipse Project
Download pong
Import pongai.jar
When importing pongai.jar it will ask if you if you want to overwrite a couple of files, just click yes or yes to all

Make some modifications!

How can we change the text in the game to say something other than Pong?
How can we make the ball a different size?
How can we make the ball go faster or slower? [Hint: look in ProjectileTracker.java]
How can we make the ball simulate gravity?
How can we make the paddles rectangles instead of circles?
How can we add another ball?
Only one ball makes the game change colors when it hits the title, how do we make the other one do it?
Make a sound when a ball hits a paddle?
Make the ball our own custom sprite?

Adding some AI: Find in the code where there is the line "// Computer AI code goes here!" The following should go right below that line. Step 1:

    paddles[ 1 ].setLocation( paddles[ 1 ].getLocation( ).x, ball.getLocation( ).y ) ;

Step 2 (get rid of the line above and put the below in its place):

double speed = .015 ;
if( Math.abs( paddles[ 1 ].getLocation( ).y - ball.getLocation( ).y ) > speed )
{
	if( paddles[ 1 ].getLocation( ).x > ball.getLocation( ).x )
	{
		if( paddles[ 1 ].getLocation( ).y < ball.getLocation( ).y )
		{
			paddles[ 1 ].translate( 0, speed ) ;
		}
		else
		{
			paddles[ 1 ].translate( 0, -speed ) ;
		}
	}
	else
	{
		if( paddles[ 1 ].getLocation( ).y < ball.getLocation( ).y )
		{
			paddles[ 1 ].translate( 0, -speed ) ;
		}
		else
		{
			paddles[ 1 ].translate( 0, speed ) ;
		}
	}
}
