Esc key. A
close event
is either the user clicking the close cross on the window or the operating
system telling the program to quit because it is going to shut down. If your program sees any
of those events, it calls a
terminate
function that prints out a message. hen it quits
pygame
to release any memory it grabbed, and it exits to the operating system.
Getting the Code to Do More
Well, that was not very exciting, was it? Let's get the code to do a little more. Take a look at
Listing 11-2.
