Ping Pong 3(In class)

For the last few weeks in CSE we've been learning how to create a Ping Pong game. Below is the code taught to the class by Mr. Miles.

// create paddle

// create the ball

// update the screen every few milliseconds with position

// start in 1D

/* things that you can do:

ball/paddle goes off the screen, comes out the other side

paddles can't go off the screen

score - the game ends when you reach a certain amount?

balls/paddles speed up as the game goes on

balls added as game goes on

incorporate top and bottom

more than 2 players

make it pretty/add music

balls can run into each other

title screen/winning screen

create a computer opponent

fix any bugs
