This book will show you, by example, how to write arcade style games for your Apple computer using the Applesoft BASIC language.

Computer Fundamentals

Even if you don’t already know BASIC, this book will give you all you need to know to create your very own games. First it reviews the Apple computer fundamentals: how to start up the computer, load in diskettes, and run and save your programs.

Shapes, Sound And Color

Then “Apple Graphics Games” will tell you how to draw shapes on the screen, how to make them move and how to add color and sound to your programs. Games paddles and joysticks can make the games you write even more realistic and exciting. You’ll find out how to use them too.

Programming

You will learn many game programming techniques as you type in the game called “Appleflight” that is developed in this book.

To use this book you will need an Apple microcomputer with 48K of memory, a disk drive and a display screen.

The glossary at the back will give you the meaning of some of the more common computer terms.

Bug Out!! Debugging Your Program

No one is a perfect typist. Chances are good that you’ll make at least one mistake when entering the program lines. You’ll discover this (and any other bugs) when you enter RUN and nothing happens. When this occurs you should see an “error message” on the screen – or you may have to type TEXT first, and then the error message will be displayed.
