Raspberry Pi for Python Programmers Cookbook - Second Edition

Overview of this book

Raspberry Pi cookbook for Python Programmers is a practical guide for getting the most out of this little computer. This book begins by guiding you through setting up the Raspberry Pi, performing tasks using Python 3 and introduces the first steps to interface with electronics. As you work through each chapter you will build up your skills and knowledge and apply them as you progress throughout the book, delving further and further into the unique abilities and features of the Raspberry Pi. Later, you will learn how to automate tasks by accessing files, build applications using the popular Tkinter library and create games by controlling graphics on screen. You will harness the power of the built-in graphics processor by using Pi3D to generate your own high quality 3D graphics and environments. Connect directly to the Raspberry Pi’s hardware pins to control electronics from switching on LEDs and responding to push buttons right through to driving motors and servos. Learn how to monitor sensors to gather real life data and to use it to control other devices, and view the results over the Internet. Apply what you have learnt by creating your own Pi-Rover or Pi-Hexipod robots. Finally, we will explore using many of the purpose built add-ons available for the Raspberry Pi, as well as interfacing with common household devices in new ways.

Creating an overhead scrolling game


By using objects and images in our programs, we can create many types of 2D graphical games.

In this recipe, we will create a treasure hunt game where the player is trying to find buried treasure (by pressing Enter to dig for it). Each time the treasure has not been found, the player is given a clue to how far away the treasure is; they can then use the cursor keys to move around and search until they find it.

Dig for treasure in your own overhead scrolling game!

Although this is a basic concept for a game, it could easily be extended to include multiple layouts, traps, and enemies to avoid, perhaps even additional tools or puzzles to solve. With a few adjustments to the graphics, the character could be exploring a dungeon, a spaceship, or hopping through the clouds collecting rainbows!

Getting ready

The following example uses a number of images; these are available as part of the book's resources. You will need to place the nine images in the same directory...
