Control the bat to aim the ball at the bricks

Getting ready

This example requires graphical output, so you must have a screen and keyboard attached to the Raspberry Pi or use X11 Forwarding and X server if connected remotely from another computer.

How to do it…

Create the following script, bouncingball.py.

1. First, import the tkinter and time modules, and define constants for the game graphics:

   #!/usr/bin/python3
   # bouncingball.py
   import tkinter as TK
   import time
   
   VERT,HOREZ=0,1
   xTOP,yTOP = 0,1
   xBTM,yBTM = 2,3
   MAX_WIDTH,MAX_HEIGHT = 640,480
   xSTART,ySTART = 100,200
   BALL_SIZE=20
   RUNNING=True

2. Next, create functions for closing the program, moving the paddle right and left, and for...
